It was three months after our 18th birthdays and a week after graduating high school when our two moms turned our lives upside down. Yes, you heard me, Tim and I have two moms.
At the time we were born, four days apart (me first), our moms and their parents were estranged, after their declaration of being a lesbian couple, and Mama Sarah and Mama Marie made the strange decision to not reveal whose son was whose when they announced that we had been born, in the hope that both pairs of grandparents would treat us equally. They gave us both the hyphenated last name Wolff-Carter, although they hadn’t been able to marry yet. The existence of grandchildren did mostly end the estrangement and we were accepted as grandsons by both families.
This secret continued as Tim and I grew old enough to realize that we had each been born to a different mother instead of being twin brothers. So, we took for granted that we had two moms and when people asked, “Which one is your real mom?” we could only answer, “They won’t tell us.”
When we were 15, they sat us down for a family meeting and finally showed us our birth certificates and the adoption papers that gave them joint custody. These revealed that Tim was Mama Sarah’s son and I was Mama Marie’s. Neither listed a father’s name. When they legally married a month later, I walked Marie down the aisle while Tim did the same for Sarah.
We had grown up loving both of our Mamas and Tim and I reassured them that knowing the truth didn’t make a difference to how we loved them.
We never expected that to be tested.
When they called another family meeting like the one when we were 15 on that Friday night in late June, we had no idea what it was about.
Once we were seated, Mama Sarah began, “Hear us out on this, please. What we are about to ask from you will sound really strange, but here goes. Mama Marie and I want more children, since you two are headed to college soon. We decided several years ago that our preference would be for the two of you to father them, but we needed to wait until you were 18 to ask.”
“What did you say?” I sputtered, looking over at Tim, who looked as stunned as I felt.
“You heard me, Aaron. You would impregnate me and Tim would do the same for Mama Marie. That way, Marie’s baby will be my grandchild and vice versa. Before you say it, 39 is not too old. Also, we should both be ovulating in a couple days.”
Mama Marie took over. “You would sign contracts like you were donating sperm and your names would be left off of the birth certificates. We would expect you to keep this a secret, let us raise them and just be their big brothers.”
Tim asked, “Couldn’t we actually do artificial insemination, like you did to have the two of us?”
Marie said, “While step-parents having sex with adult stepchildren is not a crime, we doubt any fertility clinic would agree to using your sperm.”
Sarah continued, “Besides, you can’t tell us you’ve never fantasized about us. We’ve both noticed you looking at us more and more differently since you learned who your birth moms are and aren’t. Especially when you’ve been without girlfriends and horny, like you are now. Looks you would have avoided giving us you now let linger, while you still turn away from watching your birth mom the same way.”
Marie said, “We’ve seen your Internet histories, too. You both watch plenty of both MILF and incest porn, especially the step-mom/step-son stuff, but some that pretend to be real moms with real sons, too. We also saw searches with ‘mom swap’ and ‘son swap’ as keywords, although there don’t seem to be that many videos like that, certainly not whole series like there are for daughter swaps, where two dads have sex with each other’s daughter. But it shows you’re at least turned on by the concept of incest.”
“Um… I use incognito mode. How could you know what I watch?” Tim asked, signaling that he wasn’t denying it.
I couldn’t deny it, either. The incest pornos were the videos that turned me on most. I was watching almost nothing else since Cara had broken up with me right after prom. It felt like a fixation. One I tried (and failed) to deny had anything to do with Mama Sarah directly.
Marie answered, “That mode suppresses the browser’s history, it doesn’t affect the site logging we left set up on the firewall. We’ve learned a lot about your viewing preferences. Aaron’s watching a lot of blonds like Sarah and your preference is for brunettes like me, Tim. Tell us if we’re wrong about that.”
Silence from us as we looked from face to face.
Sarah said, “So, we’re asking for a son swap, until we get pregnant, if not all summer. We’ll give you a day to think about it and talk to each other. If you’re not both a yes, we’ll go with anonymous donors instead, but we want to both be pregnant before you leave for college, either way.”
~~~~~
Tim and I retreated to his bedroom to discuss the bombshell whose fuse had just been lit.
“Can you frigging believe this?” he asked, flopping on his bed, while I sat at his desk chair.
I shook my head no. “I feel like I’m dreaming, to be honest. Not like a nightmare, but it does seem way too good to be real.”
“You’re leaning towards saying yes, I take it?”
I said, “If it truly stays between the four of us, I can’t actually think of a reason to say no. What the rest of the world would think won’t matter, because they won’t know. I would do anything to make either of our moms happy. Even this. Besides, how many times have our friends called both of them MILFs to our faces and pointed out that one is our mom and the other is just our step-mom? They’ve practically egged us on to make a move.”
Tim nodded. “Instead, our moms made the move first. And have been thinking about it for years, apparently, waiting until we were old enough. I’m… I’m in if you are.”
“Yeah. Just in separate rooms, okay? Not like those videos where the dads swap their daughters side by side.”
“Afraid to see me in action?” he asked, grinning.
“Not you, Mama Marie. It’s enough that I fulfill my fantasies about your mom, I shouldn’t be adding fantasies about my own.”
“Good point.”
~~~~~
“Are you nervous, honey?” Sarah asked, when she came into my room the next night, wearing a light blue satin robe under which I could glimpse lingerie of the same color. I was sitting on my bed in just a pair of briefs, the covers already folded down.
I answered, “And excited at the same time. Partly, I’m nervous because we’re crossing this huge taboo line in our relationship, but I’m mostly worried about disappointing you as a lover.”
“In what way?” she asked, sitting next to my feet at the foot of my bed, giving me a flash between her legs under the robe of what I assumed were panties.
“For example, if I get the chance to lick your pussy, it’s strange to think that I’d be compared to my own mother in that regard. I got some experience with doing it with Cara and she liked it a lot, but Mama Marie’s had 20 years to get to know what does it best for you, so I doubt I’ll match up. I guess what I mean to say is I’m trying to keep my expectations controlled, neither too grandiose nor too pessimistic and probably still not striking the right balance. Does that make sense?”
“Honey, relax.” Sarah slid her hand along my shin, before saying, “Focus on expressing the love we feel for each other. If we’re doing that, the rest will take care of itself, I promise. Keep in mind that I haven’t been with a man since before you and Tim were born. Marie and I dated men before we got together and were sexual with them, but we’ve been exclusive to each other for a long time. So, I could worry about being rusty at this and perhaps less experienced in some ways than your girlfriends, but I’m just not going to do it.”
“I didn’t consider that,” I admitted. I paused, then asked, “So, how should we start?”
“Kissing is usually a pretty good place,” she answered, chuckling, before she knee-walked across my bed until she was straddling my thighs, then settled onto them. She ran her fingers through my hair before she leaned forward and pressed her lips to mine.
That electric first lovers kiss went on and on, our tongues coming into play as my hands moved to caress her back, first through the robe and then against mostly-bare skin under it, my cock stiff as a rod of iron pressing between us. I couldn’t see it while kissing her, but my touch revealed she had on a one-piece teddy beneath the robe.
Before I knew it, Mama Sarah was gyrating her torso against mine, sliding her satin-covered vulva along my stiffness, and she had managed to drag my briefs down enough to expose the head of my cock. I had to break the kiss to warn her, “Keep that up and I’m going to blow my load against your stomach, not inside you where we need it.”
“Can’t have that,” she murmured and suddenly my briefs’ waistband was yanked below my balls, her groin was exposed and Sarah lifted and guided me between her labia. She dropped onto me, taking me all the way in with a grunt. She pressed her body against mine again and I felt her nipples dragging along my chest as she rose and fell, separated from me by a layer of satin as smooth as her tight pussy felt around me. I moved my hands to her hips to help guide her motions.
Although I felt things were happening quickly, I knew that cumming into her as much as possible each night during her fertile window was our primary goal, so I decided against making any effort to hold back my first orgasm and came within her after about twenty passes of her slick sheath around me, with my hips thrusting upward as well as I could with my legs still flat on the bed and my back against the headboard. “Oh, fuck, Mama!” I cried, as my cum jetted up into her five or six times.
“Oh, yes, Aaron!” she sighed into my ear as she slowed, my cock still inside her. She rocked her hips in several slow circles and squeezed with her Kegels as I realized she was inducing an orgasm by rubbing her clit against me. Backing away to look me in the eyes, she teased, “Like riding a bike.”
Once I realized it was true, I said, “I’m still hard, if you want to keep riding.”
“I do, but let’s get rid of these clothes first.” She had to lift off of me so I could pull my briefs under my butt and down my legs, while Sarah slipped off her robe and I realized the satin and lace teddy she revealed had a pair of snaps at her crotch that she’d simply undone in the same motion when she had pulled my briefs down. She pulled the teddy up her sides and over her head and I saw her totally nude for the first time.
“Gawd, Mama Sarah, you’re more gorgeous than I imagined,” I exclaimed, burning the vision before me into my memory. Mid-sized breasts high on her ribcage with large protruding nipples, a trim waist that made for a classic hourglass figure, with just a tracing of stretch marks to signify her pregnancy with Tim. A trimmed patch of pubic hair over a lovely pair of outer lips, with her inner lips barely visible from my viewing angle, but glistening with our combined cum.
Sarah smiled. “I’ve overheard your friends call me a ‘MILF’ more than once when they thought I wasn’t in hearing range. What would they think now?”
“They’re never going to know,” I answered.
“Smart man, Aaron. They think of the word as a joke, but I doubt they would be as approving if they knew you were actually having sex with me. This needs to stay our secret. As far as the world will know, Marie and I are simply using donor sperm to have two more kids because we’re not ready to be empty nesters. Conceiving them in love is a lot more fun, though,” she said, as she reached between us to grasp my cock. Giving it a gentle squeeze to check its hardness, she asked, “Ready for round two?”
“Yup.”
Letting go, she turned and dropped down to hands and knees, looking back at me while she gave her butt a shake. Viewing her pussy from behind was another moment I wanted to remember forever, her inner lips, wet and ready, peeking out at me between buttocks that were firm from plenty of exercise. Without another word, I took position behind her, notched my glans into position and pushed forward into the wetness I had left from my first ejaculation.
“I love this position,” Sarah murmured, as she pushed back at me and we set up a steady rhythm, her firm butt slapping against my legs. I wondered briefly if she and Marie ever used a strap-on dildo with each other, but realized that I would likely have heard this sound at night if they did. Then I felt some shame at picturing Mama Marie in Sarah’s place and pushed the thoughts from my mind.
I leaned forward over Sarah’s back to reach under her and grasp her breasts for the first time, loving the way her nipples fit between my fingers.
“Oh, fuck!” she cried out. “Just like that, Aaron! Your cock’s hitting my g-spot! I’m gonnaaaa cummmmm! Fuck me harder! AAAIIIEEEE!!” She started to shake and I needed my grasp of her torso to keep her from collapsing beneath me, while I resisted the urge to thrust faster into her. After a couple minutes, she took her weight on her arms again, then pushed back at me even harder than before. “I want more… of your cum,” she gasped between breaths.
I shifted my hands back to her pelvis and began a hard-quick thrusting into her, pulling her towards me as I worked myself closer to my second orgasm. Pop, pop, pop went our bodies against each other as I felt my explosion draw nearer, until I couldn’t have held it back if I wanted. I nearly saw stars as I let loose, pumping more seed into my mother, visualizing one of my sperm meeting her egg to produce a child. Boy? Girl? I didn’t care.
Sarah was pulsing around me and I realized that she was cumming again as as her moans and grunts rose in volume. I kept thrusting and when her orgasm was over, we collapsed onto our sides and my cock popped out of her. Sarah turned onto her back and raised her knees. When she turned her head towards me, I kissed her quick, too breathless for anything longer.
“You have nothing to worry about when it comes to your skills, son,” Sarah said, when she could breathe evenly again. “I may not have a lot of experience with men, but that felt amazing.”
“Thanks, Mama. I didn’t want to let you down.”
“You and your brother never have. Thank you so much for doing this.”
I looked in her eyes and saw her love for me. I asked, “Mama, If you weren’t looking to get pregnant, would this still have happened between us?”
Sarah raised her eyebrows. “Once Marie and I knew you were attracted, we would have needed to address it somehow. Taking you to bed so you could live out the fantasy and then move past it would certainly have been one option. Although you would have needed to use condoms to keep us from getting pregnant, since the two of us asking for birth control pills for just a few months would have looked suspicious.”
“Have you ever used them?” I asked.
“Our moms put us on the pill as teenagers, but after Marie and I became a couple and we stopped taking them so we could get pregnant with you boys, we never went back on them because we were exclusive to each other and didn’t see a need. Thankfully, neither of us have medical reasons to take them.”
“And you won’t need to go back on them after these babies, either.”
Mama Sarah said, “No. Marie and I will be exclusive to each other again, while you and Tim move on to college girls, so there will be no need.”
We didn’t go for a third round, preferring to let the next nights do the job if the sperm I’d deposited wasn’t enough, and fell asleep with her cuddled against my side, her head on my chest.
~~~~~
“So, how was it?” I asked Tim the next morning, when I could get him alone.
“You’re asking me how sex with Mama Marie went? I’d rather not go into details, since I don’t want to hear them about your time with Mama Sarah, but I don’t think it could have gone better as a first time together. We’ve got two or three more nights in their fertility window this month and I expect it will just get better each night. We’ll have to see whether they catch this month and whether they’ll let us continue after they’re pregnant.”
I couldn’t help but be disappointed in Tim’s answer, as I really wanted to be able to share my delight in being with Mama Sarah, but I also understood why describing it could make him uncomfortable. Imagining him being with Mama Marie made me feel uneasy as well.
~~~~~
Three weeks later, positive pregnancy tests for both moms came as both happy news and a letdown for Tim and I, as far as not having a reason to try again for their next cycle. They had only slept with us on two nights after their fertile window closed and we waited to be able to test.
Neither of us were prepared for what came next, when the true bombshells exploded.
Mama Sarah had a strange smile on her face as we finished dinner after the news, when she asked, “So, are the two of you ready to swap back?”
“What do you mean?” Tim asked.
“To make love to your other mother, of course, now that we don’t have to worry about getting pregnant by the wrong son.”
“That’s incest,” I said. “Real incest, the totally against the law kind.”
Sarah reached for my hand, before saying, “You’ve already committed incest, Aaron. You just didn’t know it. The one secret we’ve avoided telling you is who your fathers are. They weren’t anonymous sperm donors. You know them both. My brother Mike is your father, while Marie’s brother Will is Tim’s.”
My mind reeled as I jerked my hand away. What did this mean? The erection sprouting between my legs wasn’t making it easy to think. Sex with my real mom? Why did that idea both terrify and thrill me so much that I was rock hard already?
Tim made the connections first. Turning to Marie, he said, “You’re my Aunt Marie and Sarah is Aaron’s aunt. He and I aren’t unrelated step-brothers, we’re double cousins, right? Roughly equal to half-brothers? Why the hell did you not tell us? Especially before asking us to have sex with you? We deserved to know that we’d be breaking the law before we said yes! And now that you’re pregnant, these children are now proof of that crime, should a DNA comparison be done!”
Marie answered, “Which we’ll avoid. If it does come out, claiming ignorance of our blood relationship is your best defense. You might think we tricked you, but we were trying to keep you safe, to keep you from revealing your parentage to anyone before we asked you to get us pregnant.”
“Safe. Like having a baby with your nephew is safe?” I asked, worried about genetics. “I imagine you think it’s safer than having babies with your biological sons instead?”
Sarah answered, “Doing that wouldn’t have produced children who are descendants of both of us, so we never considered it. As for the risk from being our nephews, we had our DNA screened and we don’t carry any of the recessive genes that the geneticists worry about. There’s no more risk than using some anonymous donor. Do you really think we’re so foolish that we would have asked you otherwise?”
“We deserved to know, Mama,” Tim reiterated. “You let us think that we were your step-sons. Only your step-sons, rather, since we’re still that as well as nephews.”
“No, you two let yourselves think that,” she corrected. “For as long as you’ve been alive, we’ve always said that you are equally our sons and we are equally your mothers. No modifiers. That has been our truth as a family. Even if we had told you the truth from the beginning, we would still have treated you as sons, not nephews, from love, not blood. The main reason we kept your maternity a secret was so that your grandparents would treat you like the grandsons you both truly are to them, without having to reveal your fathers’ involvement.”
Marie said, “Even after we couldn’t hide your birth certificates any longer because you would need them to get your driver’s licenses, we repeated that you were equally our sons, kept giving you equal treatment and expected the same as your mothers. We never called you our step-sons, not once. You two are the ones who started calling yourselves that, who started to change how you looked at us based on your assumption of our DNA connections. Only the difference isn’t between 50% DNA and zero, it’s between 50% and 25%.”
“Well, that 25% matters. It makes what we did illegal,” Tim said. “You did describe us as step-sons when you were convincing us to get you pregnant, though.”
Thinking back, I pointed out, “Actually, Mama Marie only said that step-mothers being intimate with step-sons was legal, which is true, just not applicable to us. She knew that, but we didn’t. A lie of omission? Playing into our assumptions, for sure. Otherwise, they only highlighted that they aren’t our birth mothers, which is also true but less relevant when they’re our aunts instead.”
Tim said, “Exactly.”
Mama Marie shrugged. “When I said that, I was thinking about the decision a clinic ethicist might make, thinking you were our stepsons, which is certainly what we’d have to tell them.”
“You didn’t use a clinic to have us, did you?” I asked.
“No, you were conceived naturally. We had already been double-dating Mike and Will, it was just a question of getting them to agree to our plan and going off birth control. My point is, I didn’t say that about the clinic to convince you that you’re our step-sons. You already believed that. Yes, we avoided revealing that we’re your aunts until tonight. Had you kept your promise to treat us equally as your mothers, though, we could have asked one question about making love to us, because the answer would have been the same for both of us. Do I make love to my mothers? It might have taken you longer to reach a decision, but I believe you would have said yes. Instead, you thought one attraction was okay while the other wasn’t and we’re telling you right now that they’re both okay with us, because we don’t see them as different. I’m certainly not more interested in sex with Tim because he’s not my birth son. I love you both as my sons. I’m attracted to both of you as men. The only reason we pursued this in the order we did was to ensure we got pregnant by the desired father.”
Tim shook his head and said, “You’re still dancing around this. You took advantage of our belief that we wouldn’t be breaking the law to more easily convince us to say yes. Now, you’re using the fact that we’ve already broken the law to justify expanding the crime.”
Sarah sighed. “We debated when to tell you about your fathers. It wasn’t a question of if, but when. Maybe waiting until tonight was a mistake. Certainly, we couldn’t tell you before asking to get us pregnant, because we couldn’t let you tell anyone before you knew why it had to stay secret. Now though, Marie and I want to swap back. The same way we let our brothers swap back after they got us pregnant.”
I asked, “Huh? Uncle Will and Uncle Mike turned around and committed incest just like that?”
Marie chuckled. “Hah! That was the very reward they wanted! Our dear brothers started pursuing us as soon as we each turned 18, wanting to get into our panties. All while the four of us were double dating. Then Sarah and I revealed we were the real couple, were tossed out by our parents and moved in together. We then made the deal with Mike and Will to get us pregnant, giving them the sex they wanted with their sisters after we tested positive. The only issues they struggled with was giving up their parental rights and keeping it a secret from our parents. They were eager for the rest, especially the foursomes that followed, before they went back to college. Plus, the incest ensured that they were going to stay quiet about the whole thing. You could say you inherited your mutual attraction to us from your fathers. They were also the only men we ever fucked before you.”
Mama Sarah added, “We’re aware that sex with your mother is considered a more severe crime than sex with your aunt. Obviously, Sarah and I didn’t agree with the incest laws when we had sex with our brothers and we still don’t. We didn’t get caught then and I have confidence we won’t get caught now. If so, you have the defense of ignorance for being with your aunts, so long as you tell nobody that you know who your fathers are, while there’s no chance of a second baby to serve as physical evidence of sex with your birth mothers. If we keep our mouths shut, none of it should come out. What it comes down to is we love you both and want to be able to show it. Physically, sexually. But also equally. Based on our emotional relationships as mothers and sons, more than the biological ones. After the summer, you can move on to college girls and find your eventual wives. It’s what your fathers did and their marriages to Ashley and Willow are happy ones, to hear them tell it. We’ll give you a day to think about it, just like before. But only if you both agree.”
~~~~~
Tim and I gathered in my room to talk about it. He was clearly still angry.
Tim started, “Whenever people discuss incest being ethical, they’re always talking about it needing to be consensual. But, while we consented to the sex, we didn’t have the facts to let us consent to the incest. Does that still count as consensual?”
“Kind of a gray area, don’t you think? Is sex with your adoptive step-mother still incest emotionally, just legal? Why would it be kinky if it didn’t still have that taboo element? I took that into consideration in making my decision. I was deciding to make love with one of my mothers because she asked, without knowing that the other one would ask next. Think about this. Would you still have said yes, if they had revealed the whole story up front? I’m pretty sure I would have. I don’t regret having sex with Mama Sarah, just because I’ve learned that she’s my aunt. My one concern is the possible genetic impact on the children we’ve created, despite their reassurances. And I wouldn’t regret being with Mama Marie, if we go forward while there’s no risk of pregnancy with her.”
“You want me to say yes?” he asked.
“I want you to do what’s right for you, Tim. If your answer is no, for any reason, I’ll back you on that. But I can’t imagine you won’t eventually forgive them. It was a short-sighted strategy to get what they wanted, if they were going to turn around and reveal being our aunts anyway, but I can somewhat understand it. We were an easier yes if they waited to tell us about our fathers. But I can understand why you’re upset about it, too. I’m just feeling more disappointed in them than angry. Does that anger outweigh your love–or desire–for them, though?”
Tim thought about it for 15 seconds and said, “No, it doesn’t. Okay, I’m a yes, but I have some conditions.”
~~~~~
“What conditions?” Mama Marie asked.
Tim answered, “First, we want you to promise no more lies or evasions. If there’s anything else we need to know, we need to know it right now.”
“Nothing, we promise,” Mama Sarah said.
Tim added, “Second, we want our fathers to know that you’ve told us who they are and that they’re about to be grandfathers as well as uncles again. Even if nobody but the six of us know about it, they deserve to know that.”
“They already do. We told them our plan when they were here for your graduation party and they were okay with it, including revealing they’re your fathers. We haven’t told them we’re pregnant yet, though. When we do announce it to the families, we’ll use a codeword in the announcement–ecstatic instead of overjoyed–so they’ll know you are the fathers and we can avoid telling them over the phone. Anything else?”
“One more. We make love as a foursome from now on.”
“Why the change?” Marie asked. “When you were with me, you wanted us in separate rooms.”
Tim answered, “Not knowing that you planned this phase 2, Aaron and I still thought fantasizing about our birth moms was something we needed to avoid and witnessing you would only add fuel to that fire. We even avoided talking with each other about our nights together with you. Now, we’d really like to see you loving each other as well as get the extra experience of group sex. Who knows if we’ll ever get another chance. Besides, now that we’re not trying to knock you up, I’d love to get some more pussy eating practice and who better to teach me than your wife?”
“Tim, you licked me to two orgasms on the third night and you’re certainly welcome to give me some more, but you don’t need any lessons. You already know the most important part, which is to pay attention to how your partner is reacting, which can be different each time, even with the same partner. There isn’t anything I could say about Sarah that would help you do that better than you already do.”
Sarah said, “Aaron, that applies to you, too. You’re a wonderful lover already, because it is about love, not just fucking. There’s nothing we need to teach you that you don’t already know. Whoever you wind up with will be a very lucky woman. For the rest of the summer, that’s both of us.”
~~~~~
We started out that night kissing and already nude, lying side by side on the king bed in our mom’s bedroom, but Mama Sarah paired with Tim and Mama Marie with me. Revealed in the nude, Mama Marie’s breasts were maybe a cup size larger than Sarah’s as I already expected, her hips wider as well, but still gorgeous. She also had more stretch marks and I got goosebumps when I realized that I’d caused them.
I surprised myself in not feeling nervous. I suppose I had already conquered the emotional aspects of the taboo with Sarah, even while thinking of her as “just” my step-mother, so that only left the legal aspects as a new barrier. I broke through that barrier like it was tissue paper, finding the law a lot less important to me than our love. I began to wonder if our mother’s strategy of withholding their “aunt-ness” was the right one to get us where we were now.
“I love you so much, Mama,” I whispered at one point, between kisses.
“I love you too, Aaron. All three of you,” was Mama Marie’s response. She reached her hand down between us and stroked my cock before saying, “I want to show you how much.” She kissed her way down my chest, gradually turning her body so that her shaved pussy got closer and closer to my head, where I could lift her at the hips and swing her leg over my head to lower her snatch onto my mouth.
I noticed Sarah doing the same with Tim, just before Mama Marie’s thighs blocked my vision, and I set to my task of licking my Mama’s pussy. Her inner lips were larger than Sarah’s as well, and I started exploring them with my tongue.
Feeling my mother’s tongue make contact with my cockhead was like an electric jolt that wouldn’t stop tingling as it kept sliding around and around. It intensified when her lips surrounded the shaft, her tongue whipping around the head inside her mouth.
I had to keep my focus on eating her pussy or I knew I’d shoot off far sooner than I wanted, now that putting my sperm into a pussy wasn’t our goal. I slipped my tongue inside her vagina, tasting her sweet juices, rimming the edge, then worked around her inner lips again. Gradually, my tongue got closer to her clit. Impatient, she pressed back against my face and dragged her clit across my chin until it met my lips and I enclosed the hood in my mouth, sliding my tongue in a circle around the nub. My nose was pushing into her labia and I inhaled her scent.
Her groan around my cock nearly set me off, but I clenched my pelvic muscles to stop my orgasm, just as I felt her throat opening around me, letting me slip in. My girlfriends had never deep throated me before. “Oh god, Mama!” I cried out, before returning my attention to getting her to cum before I did. I managed to slip two fingers into her, seeking out her gspot, while I continued thrashing her clit with my tongue and suckling with my lips.
I lost the race, but not by much. I came deep into her throat, then felt her pussy spasm during my second shot as she came seconds behind me. She withdrew, letting the rest of my orgasm shoot into her mouth. I felt her swallow, as her juices flowed towards my mouth. I kept flicking my fingers across her gspot as I moved my other index finger to diddle her clit and lapped up the wetness that flowed from her.
She kept cumming and cumming, finally breaking contact with my cock to scream, “Don’t stop, Aaron, omigod, don’t stop!”
I heard Sarah scream, “Tim! Oh! Oh! Yes! Yesssss! Fuck!” and heard him grunt out his own orgasm.
He and I lay back, spent for the moment, as Sarah and Marie moved toward each other to kneel in the space between my legs and Tim’s and began to kiss. We watched them exchange the cum that they still had in their mouths back and forth, mixing mine with Tim’s. Finally, they both swallowed but kept kissing each other. Their hands moved to caress each other’s breasts.
Sarah looked down at us and asked, “You wanted to see us together, right?”
Tim answered, “Yes, Mama,” before I could. I simply nodded.
“Okay,” she said. “Join in whenever.” Our mamas settled into a 69, with Mama Sarah lying between Tim and me, with Mama Marie over her facing the foot of the bed. Tim and I watched Sarah begin licking Marie. I was looking for any particular tricks she might be using, but as she said, she was mostly following Sarah’s cues in how she responded. If anything, her advantage was in recognizing them sooner than I might have.
After three minutes, Tim turned around to lay in the opposite direction, with his head by Marie’s, as he watched her loving Sarah.
When my erection returned, I got up onto my knees and knelt behind Mama Sarah’s head. Making eye contact with me and smiling, she lined my cock up with Marie’s labia and I slid into her slowly, savoring the added taboo of entering my birth mother’s vagina. Marie moaned, “Yes, Aaron, fuck me baby.”
A moment later, she leaned over and sucked Tim’s renewed cock into her mouth, then proceeded to alternate between sucking Tim and Sarah as I shoved my cock into her and Sarah licked both of us from below.
We continued like this for several minutes, before Mama Marie came from a combination of Sarah’s sucking her clit and my thrusting. Her mouth was around Tim’s cock at the time, muffling her squeals. She didn’t stop sucking him.
When she stopped spasming, she pulled off of Tim’s cock and pulled him towards Sarah’s legs, then angled her body away so Tim could lift his mother’s legs over his elbows and push his cock into her.
I shifted my angle to stay in line with Marie and continued fucking her while Sarah did her best to continue licking us both. He and I made eye contact and I asked, “Still feels like a dream, doesn’t it?”
“Don’t you dare wake me up, if it is,” he answered.
As my thrusts and Tim’s grew more forceful, Sarah had to resort to using her hand to frig Marie’s clit and occasionally squeeze my nuts and began moaning and screaming more and more, encouraging Tim to fuck her into the mattress.
She came first, followed closely by Mama Marie, Tim, then me. The four of us shouted, grunted, shook and collapsed in a pile of bodies.
“This is going to be a fun summer,” Marie said.
“Especially if Mike and Will visit this summer for another swap while their kids are at summer camp, like he mentioned last month,” Sarah muttered.
“What?” I asked. “You’d be with them again?”
“They asked for a reunion when we told them we were going to get pregnant again by the two of you. Except, they’re bringing their wives along. Are you two ready for a bigger group?”
“What do Aunt Ashley and Aunt Willow know?” Tim asked. “Do they know about the incest?”
Marie answered, “Not yours, just the two of us with our brothers. And we can keep it that way, if you really want. But it would kind of interfere in you having a foursome with both of them.”
“They’re sisters,” I said.
“Yes. And they’re bisexual and incestuous, so they’re used to keeping that a secret, so stop worrying. Except, they didn’t limit themselves to one summer. They’ve been having foursomes with your fathers since they met in college and haven’t been particularly concerned about who fathers their children, since they’re all going to be at least cousins, regardless. It would take DNA tests to untangle how the six kids all relate to each other. Or to the two of you, since they’re all either half-siblings or cousins, instead of just some of them being cousins.”
Tim said, “I thought you promised no more secrets.”
“We promised no more secrets about things you needed to know, Tim,” Sarah said. “This didn’t qualify because it doesn’t affect you unless you want it to. So far, Ashley and Willow don’t know about you being intimate with us and your dads only know about the aunt-nephew connection. They’re just expecting a group of six, since we were planning to send the two of you on a pre-college trip to get you out of the way, if you don’t want to participate. If you do, we’ll expand the group to eight, do a family swap and bring them into our full confidence.”
“Let us think about it,” I said.

Author’s Note: So, how about it? Should I write the larger swap? Or one or two prequels featuring Mike and Will getting Sarah and Marie pregnant and then pursuing sisters Ashley and Willow in college? Let me know that or any feedback you have on this story.
