Sexual Education

It was a lazy Sunday evening, and Clair Williams was relaxing on the couch in her living room when she thought she heard her mother Sally yelling down to her from the second floor. Pausing the funny animals compilation video she was watching on her phone, Clair brushed her shoulder-length blonde hair back behind her ear and pulled out one of her air pods to listen. Sure enough, a moment later, her mother called her name again, so Clair ditched the earphones, got up off the couch, walked to the stairs, and called up, “Mom?”

The call came back, “Clair, come upstairs please. We’re going to have a family talk.”

Ever the obedient child, Clair stuffed her phone in the waistband of her leggings and headed to the second floor to see what the fuss was about. Her mother was standing outside the open door to Clair’s room and gestured for her to go in.

Upon entering, Clair frowned at the sight of her brother Blake lying sprawled out on her twin-sized mattress with a shit-eating grin on his face. Her other brother, Jimmy (who preferred to be called James now, not that the family ever bothered to do so), was sitting in the wheeled chair at Clair’s desk, twiddling one of Clair’s hair pins in his hand. Blake and Jimmy could almost be mistaken for twins, but Clair knew they had been born fifteen months apart. Both were muscular and tall (dude-bros as she sometimes referred to them), but Blake was usually more cocky and Jimmy was usually more reserved. Both brothers called her a doormat because she rarely ever stood up to them (or anyone else for that matter), but that suited them just fine; they were happy to have a pushover sibling if it allowed them to get away with things. For her own part, Clair considered herself a pacifist and rarely fought anybody about anything.

Stepping to her bed, Clair glanced down at Blake and whispered a quiet, “Move, please.”

Ever the ass, Blake moved two inches to his right and raised his eyebrows as if to ask, Good enough? Clair just rolled her eyes and sat with half of her butt cheeks on the free edge of her bed. Laughing at her discomfort, Blake finally rolled to the side slowly, as if to demonstrate that he moved only when and if he wanted to, before standing up and stretching languidly. Looking down at his frowning sitting sister with a teasing smirk, he moved to pass her and allow her access to her bed. With Clair sitting and only at 5’0″ even while standing, the towering 6’3″ Blake eclipsed her, and she had to lean her head back to glare at him. Moving to sit fully on her newly vacated bed, Clair looked over at Jimmy to see if he was going to harass her too, as she was used to her brothers working as a team, but she only received a shrug back from his direction.

While this exchange was occurring, her mother had disappeared for a moment from her place at the doorway, but as Clair was settling in, Sally came back to the room, now carrying the family’s digital video camera, usually used to film Christmases and other holiday events, on its tripod. Clair sent a questioning glance to each of her brothers, but this only resulted in another set of shrugs rounding the room. Sally fiddled with the camera in silence for a moment, setting it up at the foot of the bed facing towards where Clair was currently sitting. Unsure what was going on, Clair got up and moved to stand next to Jimmy on the side of the room, avoiding the camera. Meanwhile, all of the kids watched their mother check the picture and angle before finally standing back to break the ice.

“As you know, Clair here turned eighteen last week. I was having a talk with your aunt Diane about her latest failed relationship, and we realized that our parents missed out on teaching us some very important lessons. I recognize now that, just like my mother failed Diane and me, I have been failing you all as well. Not because I’m not there or that I don’t love you but because I haven’t prepared you all for one very important aspect of your upcoming lives properly. Well, that ends today. Your father is working late tonight and can’t join us for this, so I’m going to have to run this first talk solo. I’m recording everything we do so we can review it if necessary and so that we can make sure he approves in the morning.”

Another round of glances between the siblings and another round of shrugs ended with Blake asking, “Mom, what is this all about?”

Sally replied, “Simply put, It’s time for us to talk about the birds and the bees.”

Clair gawked at her mother at this declaration and saw that Blake and Jimmy were doing the same.

Sally glanced between her children and added, “You know… the sex talk. Our school system is failing you kids big time, so I’m going to give you all a firsthand class in sexual education. We’re all going to go through this together so we make sure none of you miss any of this important information.”

Clair saw Jimmy and Blake both cracking up, thinking surely their mother was joking. They were nineteen and twenty respectively, after all. Clair knew that both had had their share of fooling around with girls while they were in high school, though they had never let on to their sheltered parents that they were anything other than perfectly chaste little angels.

Clair, on the other hand, was mortified; her mother would never pull a stunt like this for laughs. It would be so far out of character to make a joke like this that the mere thought of the possibility was a joke itself. No, her mother had to be serious about her declaration. The idea of sitting in a room with her pervy older brothers while her mother talked about bedroom matters was terrifying. Clair had not yet allowed a boy into her life and wasn’t about to anytime soon. This was her final semester of high school, and her grades were first and only priority. Getting good enough reviews from her piano and band teachers to get into a good conservatory in the fall was the driving force in her life; she couldn’t afford to lose focus to go play kissy face behind the school bleachers. With these thoughts swirling through her head, Clair had almost worked up enough nerve to raise an objection to her mother’s premise while the boys continued to laugh, but Sally pulled everyone’s attention back with a snap of her fingers.

“Listen up! I am as serious as you’ve ever seen me right now. From my discussion with Diane, we both realized that our parents never gave us ‘the talk,’ and we both ended up afraid of sex and married to the first guys who talked us out of our pants. I ended up having three kids before I was 21 because I had no idea what I was doing. That’s the age range you kids are right now. While I love your father dearly, I know I got lucky, and I sometimes regret having made such adult mistakes when I was your age. Diane didn’t get so lucky, and that’s why she just divorced her third husband, has three kids from three different men who don’t want to talk to her, and always ends up with the wrong sort of guy! I will not let that happen to my children! Do you understand?”

Clearly in a huff, Sally looked each of her children in the eye, and when it was her turn, Clair gulped and nodded back.

Her mother nodded in approval and then moved to the side of the bed and pointed to the left-foot corner. “Okay, let’s move on, then. Blake, you stand here.”

Pointing at the right-foot corner, she added, “Jimmy, you stand here.”

Patting the center of the bed, she finished, “Clair, you sit here.”

Clair and her brothers moved to take their spots. Once everyone was in their designated position, her mother pulled a stack of notecards out of her pocket and began to read, running through a full clinical description of male / female sexual dimorphism, anatomy, the function of chromosomes, gender, gender identity, and a lot more as Clair felt herself grow more red faced, now consciously working to avoid the eyes of her sibling. Anxious to alleviate the embarrassment of hearing her mother speak on these taboo subjects, Clair found herself purposefully allowing her mind to wander, her fingers tapping out scores she was practicing or reviewing important music theory in her head. Each time one of Clair’s brothers tried to speak, Sally would silence them with an angry glare and say something to the effect of, “There’s a lot of material to get through here. Your questions can wait until the end.”

After a lengthy, but very dry, description of the particulars of male and female genitalia, Clair’s mother paused for a moment to make sure she had the undivided attention of her three pupils. It wasn’t until Sally rolled her eyes and snapped loudly that Clair’s attention was brought back to the lesson.

“That was the theoretical side. Next, we’ll do the practical bit. Remember, everything from here on out is for educational and demonstration purposes only, so don’t worry if some of the things we’ll be doing seem strange or uncomfortable. You all have to learn sometime, and I’m making that time right now. Okay, everyone, off with your clothes.”

Clair looked up at her mother, doe-eyed and stunned. Had she just said…?

When nobody moved a muscle in response to her command, Sally yelled, “I said take off your clothes, dammit! This is hard enough as it is. We don’t need to take all night with this.”

Blake called out, “Mom! Jimmy and I haven’t told you everything. We’ve both experimented with girls. We know how things work…you know, down there. You don’t have to go through all this with us!”

While Clair continued to stare at her mother in shock, Blake and Jimmy continued trying to object, each speaking louder and louder to talk over each other. After a few seconds of this, Sally put two fingers in her mouth and gave a shrill whistle, causing Clair to jump with fright.

“Zip it. We’ve got a lot of awkward material to cover, and I don’t want to hear crap from you guys at every step of the way. All right, you boys have some experience under your belt. That’s fine. I doubt either of you have done more than fumble around in the back seat of a car or some awkward humping in some girl’s bedroom while her parents weren’t home, right?”

When neither brother spoke up, Sally continued. “And have you considered how your sister is going to get along in the real world? She’s so damn shy, she blushes at a breeze. Look at her now, sitting there with her mouth hanging open at the mere mention of our subject matter!”

When her mother and brothers turned to stare at her, Clair realized how she looked and closed her mouth before dropping her eyes and beginning to blush harder.

Her mother pointed to her and said, “See? There are guys out there who would chew her up and spit her out. If you boys already think you know everything I have to teach you, then help me teach your sister too. Maybe you guys think you understand this sort of thing, but I can guarantee you don’t know everything.”

With Sally staring at them, Blake and Jimmy mumbled their agreement, and their mother continued.

“It’s a moot point anyway; as long as you want to keep living under our roof, you will live by our rules, and there are just some things you need to learn about life. Your father and I aren’t going to keep paying to send you to college when you’re probably just going to get some girl pregnant at a frat party and black hole your life like we did.”

Sally directed another glare at each of Clair, Blake, and Jimmy in turn and then said acidicly, “Okay, then. Back to the lesson. Get naked, now, or you can get jobs, pay rent, and pay for your own damn college.”

With another gulp, Clair looked to her brothers to see if they were going to continue to argue. They all knew that their mother was a bit OCD with her planning; once she started down a path, it was unlikely that she would be diverted from it by anything short of a natural disaster. Just the previous year, the family’s expensive week-long European vacation had been ruined because the kids had argued that they would rather go and do some sightseeing on their own rather than sticking to the list of family activities for the week that Sally had already organized down to the minute. A simple argument had turned into a screaming match, ending up with the entire family sitting in the hotel for seven long days while their mother glared at them.

Now with their already irritated mother demanding that they all get naked for her crazy educational purposes, Clair saw that her brothers had come to the same conclusion she had: it would only get worse if they argued with her, so there was nothing left to do but comply.

All three kids were barefoot already, as was their habit around the house. Clair watched in helpless fascination as Blake and Jimmy both stripped out of their T-shirts before standing awkwardly, both staring at the other, neither obviously wanting to go first to drop their track shorts.

“Hurry up,” Sally snipped, and the two boys bent down to pull down their shorts and step out of them. Clair shrank back in mute silence as everyone turned to stare at her; the sight of her two brothers standing over her in nothing but their boxer shorts dominated her vision. Perpetually shy her entire life, the idea of revealing herself to her mother and brothers panicked her, but Clair’s frozen state was not long lived as her mother stepped over and grabbed the bottom of her tight T-shirt and started to pull it up, tersely adding, “We haven’t got all day, Clair. Off with it.”

Faced with a dilemma between modesty and obedience, Sally’s urging helped obedience to win out, and with downcast eyes, Clair took the hem of her shirt and lifted it over her head before completely removing it. Mortified to be sitting in front of her brothers in just her bra, Clair folded her arms over top of her breasts, but her mother was having none of it. Again rolling her eyes, Sally reached out to tug on the waistband of Clair’s leggings, causing the cell phone that had been stuffed into it to fall out onto the bed.

With her exposed cleavage and chest glowing red, Clair hesitantly removed her hands from her chest and grabbed the waistband of her leggings along with her mother. Together, the two slowly pulled her tight leggings down, eventually yanking to extract her feet from the ends. Clair took care during the process to keep her legs together and her knees to one side so as to not put her white cotton panties on display for the crowd. Once her pants were completely removed, her mother took both the shirt and leggings, along with the clothes from the boys, and tossed them all in a pile in the corner near the head of the bed. Putting her fallen phone on her bedside table, Clair turned away from the group, using the opportunity to hide her assets for a little longer.

This escape didn’t last long, however, and she soon found herself facing the group once again, only she found herself suddenly less worried about being seen and more concerned about what she would see. In front of her were her two brothers, both toned and fit from years of high school sports, each wearing only a pair of dark cloth boxers–navy blue for Blake and black for Jimmy. Though she knew she shouldn’t be looking, Clair’s eyes couldn’t help but to drift down to stare at the front of those boxers and to the prominent bulges they concealed. Clair had just enough knowledge in such matters to know that it was the sight of their stripping sister, herself, that had caused those bulges.

Despite being a deep musical nerd, Clair knew that she had a naturally lithe body and feminine charms that had blossomed over the last few years. Though she told herself she didn’t have time for such base concerns, her band friends had tried many times to convince her that her youthful assets combined to give her a killer figure and that she could get any boy she wanted if she only opened up a bit. The idea that her brothers were currently being turned on by a direct viewing of her body, only barely concealed by a pair of pure white cotton brief-style panties and a matching C-cup underwire bra, made Clair shiver.

It was her mother’s loud snapping fingers that once again interrupted Clair’s line of thought. When Sally added, “Come on, hurry up, off with the rest,” Clair froze again.

This was it: she was going to have to reveal everything of herself to her mother and brothers. Knowing this made her shudder and ignited a fire that she had not expected in her lower belly. Blushing furiously and still darting glances to the distracting bulges, Clair unclasped her bra and, after a few seconds of hesitation, let it drop into her lap. To delay her inevitable exposure for a tiny bit longer, she turned around on the bed and crawled to the head to toss her bra into the pile of clothes her mother had made in the corner.

After a few seconds of lingering there and staring at her discarded garment, a stern “Ahem” from her mother prompted her to turn back around and crawl to the spot she was originally sitting. Reluctantly, she returned to her original position, but when she finally raised her eyes to glance at her family again, she found herself unceremoniously presented with her first ever view of a naked penis. Two penises in fact, belonging to each of her brothers, and each standing at half attention at the sight of its owner’s half-naked sister. Apparently her siblings had dropped trou while she was relieving herself of her brassier. Clair was so shocked at the lewd display presented to her that she didn’t even consider using her arms to cover her now naked breasts from the view of the group. The twitching of the penises demonstrated that her brothers were not upset by this fact.

As Clair sat stunned on the end of the bed, her neck began to involuntarily swivel back and forth so that her eyes were forced to bounce back and forth between the tumescent members in front of her. She heard her mother mutter quietly, “Oh for God’s sake…” before she felt a pair of hands grasp the sides of her single remaining article of clothing. With a yank, Clair’s mother pulled Clair’s panties down to her knees, forcing her legs to straighten and her knees to fall on the edge of the foot of the bed. Squeaking involuntarily in response, Clair reached down and immediately covered her vagina as her mother wrestled her last shred of dignity down her ankles and off her feet.

After tossing the offending garment to the side, her mother gave her no time to recover, stepping back and instructing, “Now we can proceed. Jimmy, Blake… Let’s start with you. Come over here and let Clair inspect your penises.”

Vacillating back and forth between succumbing to the shock of what she was seeing versus the shame of her nudity, Clair could only watch helplessly as the first two naked men she had ever seen came to stand just inches from her own reclined and revealed form. A glint seen out of the corner of her eye caused her to turn her head to stare directly into the unblinking eye of the family video camera. The blush burning on Clair’s chest began to crawl from her chest up her neck and down her stomach, and the fire in her loins began to burn harder.

Her mother came and stood on the opposite side of the bed from the camera and instructed, “Clair, please take your brothers’ penises in your hands and see how they feel.”

Glowing red in embarrassment, Clair scooted her butt forward until she was sitting on the end of the bed. Knees tightly together and hunched forwards in the hope of hiding her chest from their direct view, Clair tentatively reached up to comply with her mother’s command, though perhaps with a tad less trepidation than she had expected of herself. Having just recently recognized that her brothers, jerks that they were, were also both fairly attractive, athletic young men, the novelty of feeling a half-hard male sex organ in each of her hands for the first time was getting to Clair, and she felt an embarrassing wetness developing down below. Sally nodded slightly to approve of her actions and continued.

“Your brothers are both half-flaccid right now. The first part of our practical lesson is going to be how to arouse a man. I hate to admit it, but your father has performance issues sometimes, so I can say firsthand that this is a critical skill for any woman to have. First of all, let’s fix your positioning.”

As Clair’s hands were full, she felt her mother reach down to push back on her shoulders until Clair was leaning back slightly, arms fully extended so as to not lose her grip. Next, Clair felt her mother put a hand on each of her knees, pushing them wider and wider apart. With her butt already on the edge of the bed, Clair found her thighs moved until they were almost parallel with the end of the bed, causing her to have to push her belly forward slightly and to raise up on her tiptoes to maintain balance.

Looking down at her body, Clair realized that these changes had the effect of both thrusting her young breasts up and forward and spreading her sparsely haired vaginal lips apart to present an obscene picture of her femininity. As she felt another wave of shame-induced arousal course through her body at her forced lewd display, Clair felt both of the penises in her hands jump as all of her taboo charms were laid out for her brothers’ viewing pleasure. The potent cocktail of shame, curiosity, excitement, and arousal was now thrumming its way through Clair’s bloodstream, and she had no idea how to react to the chemical onslaught she began to experience. Fear of getting yelled at again and losing her college aspirations combined with a semi desperate need to know what might happen next kept her silent.

Leaving Clair with precious little time to consider or object to her new position, Sally reached down to enclose her hand around Clair’s right fist, currently gripping Blake’s growing penis, before starting both of their hands slowly moving up and down the boy’s shaft. Sally repeated the process with Clair’s left hand on Jimmy’s member as well, guiding both of Clair’s fists for a moment before gently removing her own hands after making sure that Clair would continue stroking both boys without her mother’s assistance. Clair felt and saw that both her brothers were now sporting growing erections as she continued to work her hands up and down their shafts. As she looked up at their faces, both had looks of confused anticipation, obviously happy to be felt up but hesitant as to the feeling party.

Demonstrating her awareness as to the reluctance of her students, Sally continued lecturing. “Arousal can involve all the senses. The sight of a hot guy, or the smell of an aroused woman, or the words of a willing partner… Any of these can all play a role. That’s why I have Clair sitting as she is and why I have Blake’s and Jimmy’s penises right in front of her. Even though you’re all hesitant about this learning opportunity, you can see that you’re all getting aroused by the sensations. Blake and Jimmy, why don’t you reach down and explore your sister’s body and see how she reacts? We’ve already covered the technical terms here. You should all recognize your sister’s vulva, labias minora and majora, mons, and clittoris. Pay special attention to that last one; it plays a crucial role in any type of intercourse with a woman.”

Clair’s hands froze midstroke, and she gasped loudly as her brothers both leaned down to eagerly caress her sensitive breasts, stopping to circle and pinch her nipples. At the first squeeze, Clair felt her toes ball up and her head involuntarily rolled back. Blake was the first to reach lower and, with two fingers, spread apart Clair’s virgin vagina, causing Clair to jump at the rough touch. Unfortunately, with her hands full and her body positioned as it was, she didn’t have anywhere to squirm, and Blake’s hand on her hip stopped any further attempts to wiggle away. Despite the rough, fumbling quality of the touches, Clair felt herself succumbing to her own rampant arousal and stopped attempting to evade the exploring hands, relaxing and leaning her head back in an unintentional display of surrender.

After a moment, Blake swapped his fingers around and pushed back Clair’s clitoral hood to lightly brush against her previously untouched clitoris. At the feeling of the first person other than herself to caress her most intimate spot, all the muscles in Clair’s body stiffened and her eyes closed tightly. Both brothers leaned in for a closer inspection of their sister’s forbidden fruits as Clair continued to shudder under their touch.

Sally’s voice pulled Clair abruptly up and up and out of her morass of new sensations. “Clair, keep those eyes open and hands moving. You’re supposed to be learning here, not spacing out. Blake, Jimmy… What would you say the state of your sister’s nipples is?”

While Clair lifted her head and resumed the motion of her hands, Jimmy drew another moan from her lips when he used both hands to tweak her erect nipples at the same time before responding.

“They’re rock hard, Mom.”

Her mother turned to Blake and asked, “And what is the state of her vagina? Is there any wetness? Are her labia engorged and spread?”

Clair felt Blake briefly remove the hand he had been using to play with her sex and saw it glimmering in the light from the cieling lamp. He said, “Her pussy is definitely super wet and her lips are wide open. Clair is definitely begging to get fucked.”

Sally reached up and smacked Blake on the back of the head. After a pause, she smacked him again. “You don’t refer to a woman’s vagina as a pussy unless she asks you to. More importantly, you respect women. Always. Got it?”

Sally waited for Blake, who was now rubbing his head where his mother had smacked it, to nod before continuing.

“All right, then. Hardened nipples and a lubricated vagina mean Clair is aroused, which means sex would be easier; she’s not ‘begging’ for anything. The willingness of the body has nothing to do with whether it’s okay to have sex with someone. You should always obtain consent from a potential partner prior to any sexual exchange. For example, Clair, tell Blake and Jimmy that they are clear to participate in sexual activities with you.”

Clair looked wide-eyed from her mother to Blake and then to Jimmy, realizing that this next step wasn’t a big one physically, but it was major symbolically, and she had no idea how wide the door that she was officially unlocking would be opened during the rest of the lessons. Despite (or maybe because of?) her fists still stroking her brothers’ hardening penises and their hands still fondling her sensitive breasts and sex, she struggled to find her voice. After a prod from her mother, Clair at last cleared her throat and quietly announced, “It’s okay. You guys can do whatever.”

Eyes rolling at the feeble effort, her mother responded, “Ideally, you would be a bit clearer with your potential partners in the future, but that will do for now, so let’s just forge on ahead. Like I said, all sensations can contribute to arousal, so learning to talk dirty can definitely help ‘grease the wheels,’ so to speak, if it’s ever necessary. It looks like Clair is reaching a point of suitable arousal but you boys are both still only halfway there. Let’s work on that.”

After riffling through the stack of index cards, her mother pulled one out from the middle and thrust it in Clair’s direction, stating simply, “Read, outloud.”

Blake had just returned his hand to Clair’s vagina and was wiggling the tip of one of his fingers in her opening while his thumb strummed on her clit. Eyes half focused and mind severely distracted by having her first sexual encounter at the hands and penises of her own brothers, Clair looked at the card and began to mindlessly speak the words written on it.

“Do you like my kitty? Can you feel how wet and open she is for you? She wants your hard dicks. She wants your spurting cum. Please, give my little pussy what she wants. She wants you to fuck her hard and put her away wet. Don’t you want to get hard and fuck me? I’m ready for you. I want it!”

Halfway through, Clair realized the extremely perverted nature of the things that she was saying and exactly who it was that she was saying them to but couldn’t quite stop herself from reading aloud each new line on the card. The rapid beating of her heart could be felt directly as throbbing from her fondled sex, and this drove her forward like a war drum, feeling intoxicated and out of control. The degeneracy of the presented speech on top of the action already in progress was like a brand-new drug coursing through her veins against which she had no defense. Because of her stroking and the dirty things she was being made to say, both her brothers were now rock hard and their precum was starting to leak down her hands and wrists. As Clair finished reading what was on the card, her mother stepped in once again.

“That sort of crude language has no place in regular life, but in the bedroom, it can be useful and effective. Note that it did the job and both Blake and Jimmy are now fully erect. I would need a ruler to say for sure, but it looks like Blake measures about eight inches and is about average in diameter. Jimmy is slightly shorter at about six inches, but it looks like he has above average girth; that’s going to be a tight fit for most women without some foreplay. Both boys should be proud, as they are packing more than enough equipment to please any woman in bed.”

Clair turned to watch as her mother walked to the head of the bed and rearranged the pillows there to place one at the top corner before beckoning to her. “For this next part, Clair, you need to be lying down. You can stop what you’re doing and move up here.”

As Clair let go of her brother’s penises, she felt a wetness on both of her hands and looked down to find a sticky mess on each of her palms. Noticing this, Sally stepped forward to take Clair’s right hand in her own, holding it up to the group and noting, “This is pre-ejaculate, also known colloquially as precum. Precum is a natural lubricant produced by the penis when it gets excited. As we discussed earlier, a man’s ejaculate contains semen; precum also contains semen, though in lower numbers.”

Reaching down, Sally wiped her index finger on Clair’s wrist and gathered up a bit of the fluid and then moved her hand in front of Clair’s face. “Here, taste this.”

Clair’s face screwed up into a grimace of disgust, and she looked at her mother to object to the disgusting request. Just as she began to protest, however, she saw her mother roll her eyes once again, and suddenly the proffered finger was thrust into her open mouth, causing Clair to momentarily sputter and gag. After a stern gaze from her mother, a cowed Clair settled down and obediently sucked on the finger. When the unexpected taste of the sharp and salty flavored goo hit her tongue, however, another involuntary shudder ran through Clair’s body as she fully processed the fact that she was licking her erect brother’s precum off her mother’s finger while sitting naked in her bed in front of all of them. It suddenly felt as if her mind was starting to float away.

After patiently waiting for Clair to fully clean the finger, Sally extracted the digit and explained, “There’s no use being shy now. At one time or another in your life, you’re almost certainly going to get sperm in your mouth, and you should learn how to handle such a scenario ahead of time so you’re prepared when it happens.”

Moving back to the head of the bed, Sally once again patted the pillow, indicating for the now numb Clair to lie down as previously indicated. Once Clair had crawled up and lay down as directed with her head on the pillow at the top right corner of the bed, her mother once again began to pull her limbs to reposition her as she saw fit. Clair was struck by the distant thought that, for the moment, she was nothing more than an obedient doll for her family to use in whatever way they desired, and this idea was met with a surge of shame and a sharp tingling between her legs. Mute compliance seemed to serve Sally’s purpose for the moment, however, as she continued arranging her daughter for the next part of the lesson.

First, she pulled Clair’s hips right to the edge of the bed. Next, Clair’s right ankle was pulled off the bed and lowered down so that her powder blue painted toenails were pointing to just barely touch the floor. Clair’s arms were laid flat by her sides and then, walking around to the other side of the bed, her mother pulled Clair’s left leg across so the foot was stretching out to rest just a few inches from the far edge. Looking down at herself, Clair realized that her swollen labia and vagina were now as widely spread and on display for her observers as they had ever been in her life. Meanwhile, her chest and breasts were heaving with ragged breaths as she tried to process the heady barrage of sensations that were bombarding her. Glancing up, she found both of her brothers were blinklessly ogling her debauched display, their erections still leaking sticky precum onto the corners of her bedsheets.

Sally continued to direct, and now Jimmy was motioned to stand directly over Clair on the right side of the bed, once again picking up Clair’s right hand and placing it on Jimmy’s hardened member. Sally stared pointedly at Clair until she realized what was expected of her and began stroking her brother’s dick, as the card had called it, once again.

“Our next item on the agenda is the male orgasm. Jimmy, you can feel free to explore Clair’s body as before; reciprocation is crucial in any sexual exchange. Clair, I want you to improvise some dirty talk. Don’t worry about potty mouth in the bedroom; it doesn’t get more intimate than a sexual encounter between two consenting adults, and trust here is essential.”

As Clair slowly stroked her brother, Jimmy reached down to tweak her nipples with one hand, causing Clair to let out an involuntary moan. When Jimmy moved his other to brush against his sister’s damp and waiting sex, Clair moaned louder and found her back arching off the bed. Assaulted by the powerful new sensations being thrown at her, Clair’s inexperienced mind seemed to dissolve and she began to babble in the hopes of satisfying her mother’s instructions. Ideas and words she never knew she was capable of expressing floated up from the depths of her subconscious and flowed out from her mouth like a waterfall.

“Oh fuck, that feels good. You’re fingering me, Jimmy. My older brother is fingering me, and I don’t want him to stop. Ooooh, if you tried to fuck me right now, I’m not sure I would be able or willing to stop you. Jesus, brother.”

Fueled by the taboo nature of their situation and the dirtiness of the things that Clair was confessing, both Jimmy and Clair were speeding up their ministrations on each other, each silently urging the other to go faster and harder. With Clair’s hand, lubricated by ample precum, flying up and down Jimmy’s steel hard member, it wasn’t long until Jimmy started to groan and Clair felt his dick begin to throb. She continued to encourage him.

“You’re going to cum for me, aren’t you, bro? Look at your slutty sister, my titties and pussy naked and on display. Begging for a fuck, like Blake said. Don’t you want to cum for me? Just let go. Let it all out, James. Oh God! Keep working my clit, James. That’s it. I’ll cum with you, bro. Come on. Just a little more! You’re almost there!”

Clair watched helplessly from her own perch on the edge of sexual satisfaction as Jimmy’s hands stilled in their motion. The powerful combination of Clair’s perverted begging and her fervent stroking of his steel hard shaft had unfortunately overwhelmed Jimmy’s defenses before he could help Clair to join him over the finish line. With a loud bellow, Jame’s body seemed to tense and his dick shot its first rope of thick, white cream out over Clair’s breasts. Attempting to avoid the spray, Clair quickly pushed her stroking hand down to point the firing cannon towards the bed rather than at her vulnerable body, but she was surprised when her mother quickly stepped in and grabbed her arm, forcing the erupting penis to take unsteady aim at Clair’s naked upper body.

Six strong shots fired out before the flow slowed and turned into a dribble, frosting Clair’s breasts, neck, chin, hands, and stomach in lines of sticky cum. Clair found herself shuddering, breathing raggedly, and eyes wide in shock over what had just occurred, having gone from nearly over the edge of orgasm to being painted in sperm by her mother’s and brother’s combined efforts in just a few seconds, causing her inexperienced and unprepared mind to melt down as it tried to process.

While Clair’s mind spun its wheels ineffectually, Sally gently let go of Clair’s arm and reached down to run a finger through the cum on Clair’s chest. “Six strong, full shots of ejaculate. That’s more than average, I’d say. See what a bit of dirty talk and a naked girl can do to a guy? Here, Clair, you should also try the real thing.”

Without waiting for acquiescence, Sally scooped up a healthy amount of sperm and once again stuck her finger into Clair’s gaping mouth. Still in shock from the circumstances and aching for an orgasm, Clair absentmindedly closed her lips and began to suckle on the finger, licking and sucking until it was clean. Once all the cum was gone, Sally drew her hand back and moved on. Clair looked over and realized she was still tightly clutching Jimmy’s softening member and let her hand fall limply down to the side of the bed.

“That was the male orgasm, as you can all see. Clair, sorry you had to get spunked there, but this is another one of those situations where, sooner or later, a guy is going to cum on you and you need to be ready to deal with it. We’ll get you cleaned up once the lesson is done. Next up, we’re covering female anatomy, which includes the female orgasm, so I’m sure you’re fine with waiting.”

Clair felt herself being repositioned again and didn’t bother to resist. The pillow was yanked out from behind her head and moved to the center of the bed, so Clair wiggled her body, scooting over to follow. As she raised her head and hips to slide, some of the lines of cum on her chest ran together and pooled in the divot just below her breasts but above her stomach. Once her head was on the pillow at the center of the bed, without waiting for prompting from her mother, Clair again spread her legs widely so that her ankles were now hanging just off the corners of the foot of the bed before looking to her mother for approval.

Sally looked back with a critical eye and nodded before holding up a finger and leaving the room. After a moment, she returned with two pillows from the master bedroom. “We’ll need for everyone to be able to see what’s going on here, so I am going to raise Clair’s pelvis off the bed for visibility.”

As her mother spoke, she put a hand under Clair’s butt and pressed up, which Clair took as an indication to lift her hips up, so she did, barely noticing the casual touching on her naked behind. First one, then both of the pillows were shoved under Clair’s hips, causing her pelvis to rise a good six inches off the bed; Clair idly noted that the cum on her stomach had now run together with the cum from her chest to form a sizable lake at her sternum. Fascinated by the sight and texture, Clair started to curiously trace her fingertips through the pool, watching the milky goo ooze and flow as her mother continued to lecture. With the distraction of the cum and the sensations of the last few minutes still fresh in her mind, Clair was barely aware that she was more now even widely on display for her brothers and mother than ever before.

Apparently satisfied with Clair’s positioning, Sally had Blake and Jimmy come to the end of the bed to continue the lesson. “Women are a bit more complex than men in terms of what stimulates them and how they orgasm. Some women can orgasm simply from penetration, some from clittoral stimulation, and some require a mix of both or something else entirely.”

Turning towards Clair, her mother asked pointedly, “Clair, have you ever masturbated before?”

Blushing fiercely at yet another line to be crossed and another privacy to be removed forever, Clair looked up at her mother with wide eyes, darting glances to the faces of her brothers and then down to their dripping penises and mewled, “Do we have to talk about this in front of Blake and Jimmy?”

Sally delivered another impatient eye roll and snapped, “That’s the entire point! You’re all here to learn, from me and from each other. There’s no need to be embarrassed about what we’re discussing; learning about the ins and outs of sex and your bodies is the goal of this conversation. Besides, you’re naked in front of them already, so it’s not exactly as if any of you have anything to hide. Now, answer the question, hup hup.”

Purposefully keeping her eyes low to avoid the gaze of her family, Clair gave a small nod in response to her mother.

“Okay, so you have masturbated before. Please tell us how you’ve masturbated and how often.”

Squeezing her eyes shut in the hopes that the world might disappear if she couldn’t directly see it, Clair quietly responded, “I’ve only done it a few times. A couple of the girls at school have pointed me to naughty videos to watch, and I’ve tried, just, like, touching myself down there…rubbing around outside and watching porn. I feel gross when I do it though… Like I’m doing something I shouldn’t be or something.”

“Well, feeling gross about pleasuring yourself is an issue that education can solve; there is absolutely nothing wrong with masturbation as part of a healthy lifestyle. Pornography is a bit trickier but, as long you as understand that it is for entertainment purposes only, has no basis in reality, and you use it in moderation, is perfectly okay for someone your age to enjoy. Have you ever had an orgasm from your masturbation? If it’s just external rubbing, I’m guessing no.”

Blushing even deeper, Clair just shook her head, prompting her mother to give a resigned sigh before continuing.

“Diane was right. I waited way too long to give you three this talk. My daughter is an eighteen-year-old virgin who thinks it’s gross to touch herself and who has never gotten herself off. I suppose some mothers would be proud of your restraint, but really, I’m just disappointed in myself that I didn’t teach you better. Oh well, nothing left to do but to give you the education you’ve been missing up until now. Okay, Clair, please spread your vagina open for us; just stick a finger from each hand in and pull it apart. Just fingertips only. I want to show your brothers what an intact hymen looks like.”

The rapid subject change threw Clair even further off balance, and she found herself shuddering at the thought of manually spreading herself open for her family. On brief reflection, it made sense as a logical next step, since she was already spread as wide as she could without human intervention, but it felt like the indignities would never stop being laid upon her. Forcing herself to take a deep breath to calm down, she averted her eyes from the group standing above her and brought her hands down from her chest to her crotch to do as her mother said. As she used her fingers to manipulate her labia and her vaginal opening, her mother seemed to take a sudden and direct interest in the activity and bent down to inspect closer. While Clair was pulling apart her outer lips and manipulating her opening, she felt a bit of lubrication building up, which was making things more slippery down below.

With her face just inches from Clair’s vagina, Sally asked, “Clair, were you using your hands to play with Jimmy’s cum on your chest?”

Still actively attempting to spread herself open, Clair distractedly responded, “Uh, yeah, I guess.” As she spoke, she finally managed to get the tips of her index fingers inside her vaginal opening and started trying to pull. It took a few attempts of inserting her fingers and slipping out before she could get proper purchase, but she fairly quickly was able to begin opening herself up as her mother asked. As she did so, she felt the lubrication that had pooled around her elevated entrance slide inside.

Pinching the bridge of her nose in obvious frustration, Sally pointed out, “So you just took your fingers…that were covered in your brother’s potent semen…and wiped them on the outside of your elevated vagina…then pried yourself open to let it run into your newly opened vaginal canal? With the angle of your hips, where do you think that semen is going to go? It’s going to go straight down inside you, that’s where! Dammit, Clair! When was your last period?”

Confused at the seemingly random change in subject, Clair continued fishing around inside herself with her fingers, attempting to get enough grip to open herself wider, and answered, “Period? Uh, maybe a couple of weeks ago, maybe? Why?”

Standing over her, Blake and Jimmy exchanged a sharp glance at this, and her mother stood up and paced a few times before shaking her head and saying, “Clair, you’re probably ovulating right now or close to it! Weren’t you paying attention to anything I told you about internal anatomy and reproduction at the start of this?”

Confused at her mother’s scolding, Clair tried to think back to the theoretical part of the lesson but could only remember the haze of embarrassed thoughts that had been running through her head and her fervent attempts to distract herself. Looking up at her mother helplessly, Clair was unable to determine what she had done wrong.

Sally was shaking her head with a disgusted look on her face. “Bah, the damage is already done now. If you don’t want to pay attention when I try to teach you these important life lessons, maybe we’ll just let nature run its course for a few weeks and see if you’ll learn your lesson from real life. I’ll bet you’ll be a lot more receptive towards my help if you have to deal with the consequences of your actions.”

The sound of snickering brought Clair’s attention back to her brothers at the foot of the bed; they seemed amused by this pronouncement, which confused Clair even further.

After a moment, her mother calmed down and returned to business. “Okay, pay attention everybody. Hopefully you can all learn at least a few things today. For now, boys, can you see inside your sister?”

Blake craned his neck but shook his head. “Looks like Clair is pretty tight down there and not spread enough.”

Leaning in closely, Sally examined her daughter and confirmed this was the case. “Clair, you’ve barely got the tips of your index fingers in. I don’t have a speculum on hand, so you’ll have to get more fingertips in to spread yourself wider.”

Despite having strong fingers from a decade of playing piano, Clair found it difficult to insert multiple fingers into her virgin vagina to pull herself open any wider. A self-proclaimed perfectionist who never allowed herself to fail at any task, Clair redoubled her efforts. After a few moments of struggling without making any progress, she frustratedly pulled her hands away from her sex, reached down to her chest to the only source of lubricant she had readily available, and made sure to cover her index, middle, and ring fingers on each hand with an ample supply of cum. Reaching back up to her raised pelvis, she made a concerted effort to force three fingertips from each hand inside herself to pry apart the walls of her tiny opening.

Had she been watching the faces of her mother or brothers, she would have found them mouths agape, in shock at her actions. Sally slapped her hand to her forehead as Clair continued with her work, unwittingly transferring a much larger second helping of her brother’s semen into herself. Clair, on the other hand, was now finally making progress; with more lubrication and more fingers, she finally managed to pull her opening as wide as she could. Though she felt sore and stretched, when Blake and Jimmy leaned forward to stare in amazement, she knew that she had achieved success.

Clair’s triumphant face seemed to break her mother out of her shock. Still shaking her head and muttering to herself, Sally walked to the other side of the bed to pick up the camera. Clicking a button to turn on the bright LED light on the front, she pointed it into Clair’s spread hole from a straight angle and commented, “Well, we would be able to see your sister’s hymen if there wasn’t now a copious amount of Jimmy’s ejaculate covering it up. We’re going to need to remove that pesky barrier to continue the lesson anyway, so we should just get rid of it now. Clair, you can stop stretching yourself open; instead, I want you to take your right palm and lay it flat on your mons pubis with your middle finger resting between the lips of your labia with the tip over the entrance to your vagina. In a moment, you’re going to insert that finger into yourself as deep as possible. I’ll be right back.”

Knowing she was going to be sliding it up into herself, Clair took her middle finger and gathered up the scattered remnants of Jimmy’s cum from her stomach while her mother was gone and then positioned her hand over her opening as her mother had directed. She had just begun to slide the gooey finger up into herself with an audible squelching noise when her mother returned with a damp washcloth and continued instructing.

“Good, now keep sliding your middle finger deeper. Soon you’re going to encounter a membranous barrier with the tip of your finger. Do you feel that?”

Grunting at the feeling of her first ever penetration, Clair arrived at the barrier her mother had described and nodded.

“Alright, this next part is going to be painful, but every woman has to go through it at some point, so don’t be afraid and know that the pain will fade quickly, especially after we continue the lesson. I want you to take your left hand and put it on top of your right. Yes, just like that. Now, I want you to use both hands and push as hard and fast as you can to force your middle finger as deep as it can go and then bend the finger like you’re making a ‘come here’ gesture several times. You’ll want to do this quickly, as it will likely sting, so be brave and go fast.”

Clair followed her mother’s instruction and layered her hands then got ready to shove. With a loud grunt and a grimace, she forced her middle finger through the barrier and felt a brief tearing sensation but didn’t allow herself to stop until her finger was in as far as it could go. Bending her finger caused a further burst of pain, but not as much as the initial shove. Waggling her finger several times, Clair was just beginning to feel the balance of sensation transitioning from pain to pleasure when her mother indicated for her to extract her digit. Clair looked down in amazement to find the finger covered in a mixture of blood, semen, and her own fluids.

Cooing gentle words of congratulation and comfort, her mother gently used the washcloth to wipe down Clair’s hand and the area around her still slightly gaped vaginal hole. Once the cleanup was complete, her mother continued. “Great job, honey. I’m proud of you. I know this is painful, but it’s a right of passage that every girl needs to go through to become a woman. There is an upside here, though. Now comes the reward for your bravery: it’s time for you to have an orgasm.”

Clair was already positioned with her head on a pillow, her back on the bed, two pillows under her butt, and her legs spread wide towards the edges of the foot of the bed. Lifting Clair’s right ankle up and back, Sally pushed it to a spot above Clair’s right shoulder and told Jimmy to grab it and hold it there. Repeating the same motion on the left side, the other ankle was handed to Blake. Looking down, Clair found that, between the new position and her previous manipulations, the glistening opening to her most private place was now winking open, a smear of white goo still visible around the edges, facing almost directly upwards.

Sally checked her positioning to make sure it was correct and then continued. “Clair, go ahead and spread your vagina all the way open again so we can see inside again.”

At her mother’s command, Clair dutifully reached down again with her fingers, many still damp with her brother’s semen, and ran them between her labia and into her opening to pick up more lubrication. She then once again use three fingertips on each hand to pull apart the opening of her sex. The insertion and spreading was much easier this time, thanks to the previous spread, the removal of her hymen, and the copious amount of cum in and around her hole. Her mother used the camera to peer inside again and then gestured for her brothers to lean forward and take a deeper look before continuing.

“As you can see, Clair’s hymen is no longer blocking the view deeper into her vagina. There’s still quite a bit of sperm inside, but that’s all resting at the back of her vaginal canal now where it’s pooled against her cervix. If the fluid wasn’t present, you would be able to see her cervix, which looks kind of like a pink, doughnut-shaped opening from Clair’s vagina into her uterus, or womb. Normally, a fertile eighteen-year-old girl who wasn’t trying to get pregnant wouldn’t want to find herself on her back with her hips raised and her cervix pasted with fresh sperm, but since Clair had already inseminated herself several times now”–Sally paused to shake her head–“we’re not going to worry about that for today, and for the purposes of our demonstration, we’re going to power through. Clair, you can pull your fingers out for now.”

Clair pulled her hands away from her sex, but thanks to her recent activities, her hole was still visibly dilated. Leaning her head back and dropping her arms, she allowed herself to relax for the first time in several minutes and looked around. Jimmy’s face was a mask of lust as he stared with laser focus at her gaped sex; he didn’t even notice her staring at him in disbelief. Looking down, she found that his penis was once again fully erect with clear fluid dripping from the end down onto her bedspread. Traveling sideways, her gaze found the same look of unbridled passion and dripping member sported by her brother Blake as well.

In that moment, the singleminded concentration of the last few minutes shattered and the realization hit home in Clair’s mind that she had just lewdly spread her sex and taken her own virginity in front of the watching eyes of her brothers, her mother, and a camera. A shiver traveled over Clair’s sweltering skin, and a moan involuntarily crept its way up from her throat to escape from her barely opened mouth. Her toes squeezed tightly together in involuntary excitement, and in front of the watchful eyes of her family, the mortified girl saw her gaped sex spasm shut for just a moment, forcing out a small dollop of errant sperm and her own lubrication, which then ran in a small river down her pelvis, across her hip, and to the bedspread below.

Full body once again blazing red in embarrassment, Clair tightly closed her eyes but realized that she could not hide in her current position with her brothers holding her legs. Feeling that she was drowning in feelings of shame, arousal, desire, curiosity, determination, and a million other confusing emotions, Clair’s stubborn perfectionist nature automatically took over. Giving herself no choice but to doggedly continue on and finish what she had started, Clair decided to embrace the ridiculousness of her current situation and forced herself to open her eyes and look up at her family with a wan smile. Clair read from their astonished faces that they were wondering at her internal drama as it had unfolded but knew there was nothing she could do about it but carry on.

After a moment, her mother cleared her throat and said, “Well, the next step was going to be making sure that Clair was properly aroused and lubricated, but I think we can all agree that step won’t be necessary for this session.”

This bit of out of place humor brought a round of nervous laughter from the group, and the tension of the moment seemed to defuse slightly. Sally gently took Clair’s right hand and once again returned it to her upturned vagina.

“Believe me, honey, you’re going to like what’s coming up next. This is the fun part. Now we’re going to learn what gets you off. Like we discussed previously, it’s likely going to be some combination of insertion into your vagina, stimulation around the entrance, stimulation of your g-spot, which is an inch or two in and on the top side, or stimulation of your clittoris. I’d like you to try a few of these things out, and let’s see what gets your motor running.”

Unsure where to start, Clair thought about what Jimmy had been doing to her before he covered her with his cum. With one hand, Clair began to rub up and down her outer labia, and with the other she reached up to cup and squeeze her breasts, making sure to pay plenty of attention to her still diamond hard nipples. Assuming that she was expected to talk dirty through her own orgasm, similar to how she had been instructed to help get her brother off, Clair began to say whatever came to the top of her mind, unable to focus much on anything but the movements of her hands and the sensations they were generating below.

“I can’t believe I’m jilling off in front of my mom and brothers. I just popped my own cherry, and now I’m fucking my own hands in front of my family. Jimmy already sprayed his nasty cum all over my body, and now I’m using it to masturbate with. Blake has been dripping onto my bedspread for the last half hour… I bet he’s wishing he could fuck me like one of his high school skanks. I’m so horny, I think I would let him. God, I feel like such a slut.”

Experimenting with penetration, Clair gingerly inserted her index finger into herself; first the tip, but eventually half her finger. Finding that she liked the sensation, she pulled it out and slowly pressed it in again. After a few repetitions, Clair found a rhythm and started pumping the finger in and out faster, now shoving it in up to the second knuckle, while using the thumb of her same hand to flip her clitoral hood up and down.

Meanwhile, her left hand was squeezing and kneading her breasts so hard that, in the back of her mind, she wondered if she was going to leave bruises, but her animal urge to cum was more powerful than her sense of self preservation at this point. Despite knowing that her mother and brothers were standing just inches away from her and that a camera was recording all of her words she was saying, she found herself unable to care about anything other than her impending climax. The shame of knowing her perverted display was being observed just drove her along faster, compelling her to fuck herself harder, so she pulled her index finger out of herself and replaced it with her middle and ring fingers twisted together, using her wrist to drive her hand in and out, in and out, over and over again while she continued to babble.

“I am one. I am a slut. A normal girl doesn’t end up on her back between two naked guys, finger-fucking her own brother’s cum into her pussy. And it is a pussy, Blake, no matter what mom tells you. Vaginas have sex, pussies get fucked, and this pussy wants to get fucked.”

Sensing herself nearing the finish line and aching to storm over the edge at full steam, Clair brought her left hand down from her breasts to expose her clit and began to flick her sensitive love button like she was playing piano in a hurry, prestissimo and staccato. This rapid jolting on top of the rest of the overwhelming array of sensations raging in and around her was the final impetus that sent her reeling over the edge. As Clair started to cum, she looked up at her mother, who had a concerned look on her face. Grimacing, Clair apologized as she exploded. “I’m sorry, Mom. You raised a bad girl. I…am…a…SLUT! Ooooooh gaaaahhhHHDDDDD!”

With this final declaration, Clair finally caught up with the orgasm that she had earlier been denied. For the first time in her life, Clair felt her spasming vagina clenching on her young fingers and saw nothing but stars and fireworks.

ohfuckohfuckohfuckohFUCK!

Toes curling and muscles spasming, her legs shook hard against Jimmy’s and Blake’s unyielding grips as her head rolled back into her pillow. The breath seemed to catch in her throat forever as the tide of her orgasm violently washed all thoughts from her mind until there was nothing left but darkness.

***

Cool, damp pressure on her face eventually roused Clair from her slumber. Opening her eyes, she found her mother standing above her with a concerned expression on her face, patting a wet hand towel on her forehead. Glancing downward, she was accosted for a brief moment by crippling panic at her sensationally exposed state, but the memory of the last few hours came flooding back to her quickly, allowing the anxiety to fade into a more manageable background haze.

When Sally recognized that Clair had come to, Clair watched her set down the towel and step back from the bed, the concern on her face being replaced by a warm smile.

“I told you, honey, that was the best part of the lesson so far, right? I don’t think any of us expected you to be quite so…successful…in your demonstration, however. Blacking out after an intense orgasm is unusual but not unheard of, so it certainly sounds like that one was a doozy. Don’t worry though; as you get used to the sensation, that will likely happen less or not at all.”

Her mother paused for a moment, obviously uncomfortable with what she had to discuss next. After a few false starts, she spoke slowly and carefully, picking her words. “Some of the things that you said while you were pleasuring yourself…may have…felt right to you…in the moment. Yeah? But I want you to know that none of them are things you have to worry about being true, okay? Things you say and do during sex will often diverge from who you are as a person. It can add a bit to the fun to say naughty things, but that doesn’t mean that it always sources from who you are as a person, okay? We can have some one-on-one time later to talk about this more in depth if you would like, alright?”

Clair quickly nodded to her mother and kept her eyes averted, hoping that the subject might change quickly. The shame was returning to pour over Clair like a waterfall as she remembered the depraved things that had come out of her mouth while she was attempting to get herself off. In the moment, it had felt as if someone else had been speaking through her, though she clearly remembered the words had come from between her own lips.

Having received Clair’s acknowledgement, Sally once again returned to business mode. “Good. Now, Clair, I want you to bring your knees to your shoulders again. Blake, Jimmy, go ahead and hold your sister’s ankles, just like before. I want to show you all something.”

Clair realized that when she passed out, her brothers must have released her legs, so she lifted them back towards the headboard. As Blake and Jimmy each took hold of an ankle, Clair looked down to see that her pussy was opened up to around a finger’s width without any external intervention, thanks to her recent activities. It did not surprise her when her mother asked her to once again spread herself open so that everyone could look inside, but she did find it much easier to comply this time. In no time she was able to insert the tips of three fingers on each hand to spread her hole even wider than before. The feeling of stretching hurt just a little, but it was a good hurt and she found herself longing for a deeper stretch.

The camera was brought in for another closeup of Clair’s gaping pussy before being returned to its watchful position at the foot of the bed. Blake and Jimmy were then waved in for another up-close inspection.

“As you can see, Clair’s manipulation of her vagina and the associated orgasm that she recently enjoyed led to two noticable changes. The first change is the relaxing and flexing of the tissue around her vagina, making it more malleable and allowing it to stretch and expand more easily; you can see that she has spread herself much more widely with less time and effort than a few minutes ago. The second change is harder to determine, but you might notice that you can now see much deeper into her vaginal canal than you could previously. Do any of you remember why we couldn’t see Clair’s cervix before?”

Jimmy spoke up. “Because of all my cum she stuffed in there, right? It was blocking the view.”

Sally nodded and continued, “That’s correct; Clair’s vagina previously had nearly an entire load of Jimmy’s ejaculate inserted into it by her foolish actions. Looking now, you can see little of that sperm is still visible. A small amount of it was pulled out by Clair’s masturbation, as you can see here.”

Sally’s finger traced a damp line down from just below Clair’s upturned opening, along the sensitive skin of her perineum, dipping briefly into the small blob of cum filling the dimple of her anus, and along her butt and hips to where they met the stack of pillows and bed. The wet finger was then wiped off on Clair’s dry leg as Sally continued.

“A bit may have also been squeezed out when her legs came down when she passed out, but we don’t see too much external leakage. I say external leakage, as most of it went somewhere else entirely: into Clair’s body. You see, when a woman orgasms, many things go on inside of her. You saw the muscle twitches, the eyes squeezing shut, and her toes curling up… These are all just incidental indications of pleasure that occur when a woman climaxes. The important, yet hidden, biological function fulfilled by the female orgasm is that the cervix dilates and spasms, dipping and opening slightly in an attempt to draw any fluid near it up into the uterus. This means that most of the sperm we saw inside Clair earlier that was puddled around her cervix was likely pulled up into her womb when she got herself off.”

Clair wondered at her mother’s words. Did that mean that Jimmy’s sperm was trapped inside her now? The wickedness of the idea caused her skin to grow goosebumps, despite the heat in the room, and she desperately wanted to masturbate again, but she restrained herself and continued holding herself open as her mother kept speaking.

“Based on what we covered during my initial lecture, there are a number of things a fertile young woman can do to help herself out if she accidentally gets sperm inside of herself in order to reduce her odds of conception. These include avoiding an orgasm, making sure to stay upright so that gravity can assist with causing the sperm to flow out, or thoroughly washing herself out. Clair, who obviously wasn’t paying attention earlier, hasn’t been doing any of these things and apparently doesn’t care to help herself out on this front. It’s obviously too late for most of those steps now so, for the purposes of this demonstration, we’re just going to plow on. Clair, you can take your fingers out, and Blake, Jimmy, you can set Clair’s legs down here and here. Blake, I’ll need your help for the next demonstration, so please hop up on the bed.”

Clair had a flash of concern and confusion when her mother mentioned conception but was quickly distracted when her brothers dropped her legs back to the bed and Blake climbed up to kneel between them. Clair’s lower half was now arranged such that her thighs were flat to the bed in a wide V shape and her ankles and toes were pointed straight down away from her. Thanks to their positioning, she now had an excellent view of Blake’s upturned, throbbing member as it rested just inches from her gaping hole. With her hips still raised by the pillows and spread as she was, she was sure Blake was getting the viewing of his life. Clair almost felt like she was in a gynecologist’s office and that her brother was the doctor getting ready to give her an inspection. Though she had only been to the gyno a few times ever, Clair was certain that it was not normal for the doctor to be fully nude…or to be sporting such a magnificent erection.

Continuing to stare, Clair’s attention became increasingly focused on the cock in front of her. Emotions surged in her chest and in her pussy, and she discovered a burning need within herself to see how it felt inside of her. But it was her brother! How was she supposed to rationalize these two disparate ideas in her head? Why did she want this so badly when it was so wrong?

Could she say she was afraid with a straight face? No, that wasn’t it at all.

Was she ashamed of what she and her siblings were doing? Maybe a bit, but that wasn’t where the butterflies were coming from.

Was she curious to know what it felt like? That was definitely part of it, but not the main drive.

Was it the anticipation of the inevitable act? Not quite, but almost there…

It was lust. Her body was on fire with the desire to get fucked right now, and the forbidden idea that her older brother was going to fulfil that need for her was driving her absolutely crazy. While this perverse idea swirled in her head, Sally kept up her instruction.

“Blake is wielding a very impressive weapon down below, which is one of the reasons why it was important for Clair to do some preparatory stretching, removing of barriers, and relaxing before this final step. We’ve come to the end of our practical lesson, and all that is left for us to demonstrate is sexual intercourse.”

Unable to stop staring at the object of her distraction, Clair watched as Blake’s hardened member twitched and oozed a drip of precum from its end to drip down onto the bedspread between her knees as their mother calmly announced that Blake was going to fuck his sister.

Blake was obviously excited at the idea, but Clair wondered… Was he only excited because she was an available, naked, young woman, or did he too feel that special thrill because she was his innocent little sister? Because of the lesson, she had been performing all manner of dirty activities for him and Jimmy through the evening, and she couldn’t fault him for his desire either way. Silently, she found herself hoping that he felt the same way about her that she felt about him.

Despite what her mother had said and what she chose to tell herself about the things she had said while she was trying to get herself off…that she had been caught up in the moment or that it was all just dirty talk…Clair knew that, deep down inside, she had meant every word. As amped up as she was on teenage hormones right now, the idea of fucking her studly jerk of an older brother was more attractive to her right now than all the musical scholarships or performance grants that she had ever wanted. They were two thirds of the way down the road to incest, and Clair wanted to sprint to the finish.

Glancing down at Blake’s dripping member, Sally commented, “My plan was to have Blake wear a condom for this step, but Clair’s previous self fertilization has made that a moot point. After this lesson on intercourse, there was going to be a theoretical lesson on how to make a baby, but due to circumstance, we’ll go ahead and make it a practical one instead. Maybe having a bit of a scare will drive home what’s really important about this lesson for Clair and she can stop by the pharmacy tomorrow to set herself right. Okay, Blake, you’ve done this before, so go ahead and show Clair how this step works. Be gentle now, and remember that it’s her first time.”

Clair felt a brief flash of concern as her mother spoke about impregnation but barely had enough time to consider the implications before Blake was looming over her, running the head of his perfect penis up and down between her labia.

Christ, it felt good.

Blake asked, “Ready, sis?” but barely gave her time to formulate a response before starting to ease forward into his sister’s welcoming pussy. All Clair could do at the feeling of being taken was moan out loud.

“Oooooh my GAHD!”

With several short thrusts, Blake was able to get the first five of his eight inches wedged up inside of Clair’s suddenly very happy hole. A need to make him feel as good as he was making her feel overcame her.

“Jesus, Blake, your dick feels amazing. Fuck me, bro. You don’t have to go easy. Just fuck me as hard as you want.”

Rising to the challenge, Blake picked up Clair’s ankles and set them on his shoulders before leaning forward to thrust again, and again, and again. Thanks to Clair’s previous stretching, he was able to get almost his entire shaft inside in less than a dozen strokes; this was something he had never accomplished with any other woman.

Blake was now hammering into Clair, and both siblings were grunting with each heavy stroke. Having never experienced anything like this, Clair was flitting from orgasm to orgasm like a dragonfly dancing on the surface of a rippling pond. Their mother didn’t let the sight of her son rutting on top of her daughter interrupt the lesson, however.

“As you can see, Blake’s penis is doing a much better job of satisfying Clair than just her fingers alone. A competent partner and penetration from an appropriate phallus can go a long way. Not to dictate your sexuality, honey, another girl could do just as fine a job. Just be cognizant of what sort of stimulation takes you the farthest, and make sure to communicate with your partner.”

Clair was feeling delirious with dopamine and was happy to communicate with her loving brother who was making her feel so unbelievably good.

“Fuck me, brother. Keep slamming me, yeah. Make it so I can’t walk straight after! Come on!”

Clair’s body felt like jelly being stirred inside the jar, and Blake was still pumping away. From the speeding up of her brother’s breathing and the tight clench of his jaw, Clair took immense satisfaction from the idea that it was her body that was getting her brother close to the edge of sweet release. Tightly gripping his shoulders, she leaned in and stared straight into his eyes as he continued to thrust into her wildly.

“Ooooh, are you getting close, Blake? Are you going to fuck your load inside your little sister? Oh God, that’s so hot. Jimmy’s cum is already in my womb, and now it’s your turn. Don’t hold back, bro. Cum deep inside my little pussy. You know you want to!”

Sally cut in here. “Clair has already had multiple orgasms at this point and has astutely noticed that Blake is getting close. You can tell from a variety of factors, such as the change in Blake’s facial expression, the tightening of muscles in his back and legs, and the increased speed of the copulation. Usually, when a male ejaculates, he sends a standard volume of semen out, but there are a few things you can do to increase that amount if pregnancy is your desired outcome.”

With detached fascination from her multi-orgasmic plateau, Clair watched as her mother reached down behind Blake with both hands and did something. Almost immediately, Blake’s fevered thrusting ground to a halt and he let out a loud moan, his face falling slack with pleasure as he fell forward onto Clair heavily, driving himself fully into her as his dick started jerking wildly. Their mom seemed to be counting the jerks as she moved her hands in time.

“One, two, three, four, five, six, seven, eight, nine, ten, eleven. Eleven strong shots of semen, fired deeply into Clair’s receptive vagina! Adding in Jimmy’s load from earlier and the precum that Blake has been leaking there since the beginning of this part of the lesson, and accounting for the fact that both brothers are near their biological sexual peak, that likely amounts to between a quarter to a half a billion sperm wiggling around in her reproductive tract.”

Breath still coming in great heaves, Blake separated himself from his sister’s sweat-covered body enough to give their mother a pleading look that confused Clair momentarily. With a sheepish grin, Sally looked down to her hands behind Blake’s rear and then slowly drew them back from his body.

“Sorry for the surprise, honey, but the main two methods that can be used at the moment of orgasm to increase a male’s volume of sperm ejection are fondling of the scrotum and prostate massage. Since this is our only demonstration of intercourse for the evening, I decided to show you both at once. You can definitely see the difference it made however; Jimmy earlier fired only six shots during his orgasm, but Blake, you were able to manage eleven. I bet your testicles are feeling a little drained right now, huh?”

Pulling himself up and out of Clair with a squelch, Blake could only groan as he reached back to tenderly feel his violated backside for a moment before lifting himself first off of his sister and then off of the bed. Sally stepped forward to investigate the mess that had been made of Clair’s now well-used vagina, picking up the camera to give it an up close view of the puffy red flesh and oozing white cream contained within. Reaching down with her free hand, she walked two fingers up Clair’s crotch from the top of Clair’s slit to a point a little higher up on her mons before looking around to make sure she had everybody’s attention again.

“This point is around three to four inches deep into Clair’s vagina. About here is where we would normally find the cervix in a non-aroused female of average size.”

Walking her fingers a little higher, Sally continued. “This point is about eight inches from the entrance of Clair’s vagina. During sexual intercourse, as well as childbirth, the vagina, as well as the cervix, can expand like an accordian. We saw from Blake’s penetration that he was able to fit his entire penis inside his sister, demonstrating the amazing elasticity of a woman’s body.”

Pausing her explanation for a moment, Sally made eye contact with each of the siblings in turn.

“Make sure you all take note: Foreplay is not just for kicks; it helps to generate lubrication, stimulate blood flow, and to allow the tissue of the female’s reproductive system to have time to stretch and prepare. In the case of Blake’s intercourse with Clair, it’s likely he was stretching her to the limits of her comfort, which is why all of the preparatory activity was so important. When he ejaculated, he was likely ‘bottomed out’ in her vagina, so to speak, meaning that his glans was nestled adjacent to Clair’s cervix, which would have been naturally dilated from her constant orgasms. For the purposes of insemination, we couldn’t have arranged for better circumstances if we tried, and much of Blake’s ejaculated genetic material passed immediately into Clair’s uterus. If you take a peek in her vagina, which is now nicely spread all on its own, you can see that there is a lot less fluid in it than you would expect from the size of Blake’s ejaculation.”

Pausing to give the siblings time to peek at Clair’s stretched opening, Sally then brought her fingers up higher and to the sides, gently pressing on two points just below Clair’s hips

“This spot here and this spot here are approximately where Clair’s ovaries are. What you failed to pay attention to during my lecture earlier, Clair, is that, with the timing since your last period, one or both of those ovaries will have likely either already released an egg in the last couple of days, or will be doing so shortly, as part of ovulation. Those released eggs will move to your fallopian tubes, here, for up to a few days, while waiting for visitors from below.” Her mother’s fingers traced the theoretical path of Clair’s fallopian tubes before allowing her right palm to come to rest over the center of Clair’s pelvis.

“Unfortunately for your current situation, Clair, your fallopian tubes are connected to your uterus, here, and your uterus is currently swarming with hundreds of millions of fresh sperm from your recent sexual activity. Each of those sperm are currently attempting to blindly wriggle deeper into your body to find any waiting eggs and would like nothing more than to force their way into an egg to fertilize it. If one of those millions of competitors succeeds in their goal, the egg will continue to your uterus and will attempt to implant itself. If that step is also successful, this flat little tummy of yours is going to swell up quite unfashionably over the next nine months. In a healthy young woman like you, Clair, with highly motile sperm from fertile young men like you, Blake and Jimmy, the chances of conception are going to be very high. In fact, the main limiting factors here would be timing and access.”
