Lauren, My Slut Girlfriend

*

Lauren and I had been dating for a couple months. I should mention that she had been in a pretty serious relationship before we started dating. When I say before, I mean that the week we met I tried to make a move on her but she told me she was seeing someone. When I saw her again (two weeks later) she told me she was single and half an hour later we were in my bed.

It was kind of strange for her to jump right into a new relationship with me, or at least that’s what her friends told her. So they convinced her to keep going on other dates.

That’s what Lauren told me one night early on while we were lying in bed, “Every now and then my friends set me up on blind dates. I don’t really think I can get out of it. It’s not a big deal, just grabbing coffee. You don’t mind do you?”

I’m a pretty secure guy and I really enjoyed being with Lauren so I said it was fine. I mean what could the harm be? Plus I can’t blame her for enjoying flirting a little bit on a date, don’t we all? In fact, I was somewhat guilty myself, I still had a tinder account active from before we started dating and logged on occasionally to swipe right on the hot ones in hopes of some fun messages.

That’s actually how this got started. I was bored one friday evening while working on a grad school project and idly swiping right when I came upon a profile. Lauren, 28, red head. The profile picture was of a woman taking a mirror selfie in a short black dress. It was definitely her. I flipped to the next photo and was shocked to see a picture I thought she had only sent to me. It was only from the shoulders down but she was standing sideways, topless, her breasts covered by one hand and wearing a black skirt, thigh highs, and heels.

Intrigued, I went to the next, and last picture. I was shocked to see it was her in one of the lingerie outfits I bought her for christmas. It’s a red thing, the back looks like a short tight dress but the front is just five bands of lace material. Each band was about an inch wide and the top one just barely covered her nipples, leaving the rest of her breasts exposed. The bottom one just hid where her pussy lips would show but her shaven mound was on display.

Just the sight of her was starting to get me hard, but what was she doing with that kind of profile on tinder? I wanted to ask her about it so I messaged her to see what she was doing.

“I’m out for coffee remember?” was her response.

I had totally forgotten that tonight was one of her blind date nights. She knew I was going to be working late tonight so had agreed to a blind date with a friend of a friend. We had an arrangement where she was going to let me know when the coffee date was over so we could meet up and spend the night.

As this was all going through my mind I saw that she had her location turned on on her messenger. Curiosity getting the better of me I clicked on it. Funny, she wasn’t in the part of town with the coffee shops, she was in the nightlife area.

I thought about what to do. Normally I probably would have finished my work and asked her about it later. But seeing her on Tinder had made me curious, and horny. So I called it quits on work and headed into town. I tried a few bars before I found her. She was sitting at a cocktail table with some guy, her date. She had a martini glass in front of her and was wearing another red dress. This one was classier but still very sexy and I know from seeing it before that it’s pretty short. She had her back to me so I walked over to the bar where I could sit and watch her from the side, hopefully without being noticed.

I got a beer and sat and watched them. They seemed immersed in their conversation, Lauren kept laughing at his jokes and seemed to be having a really good time with him. I saw him order her another drink and she eagerly accept. Eventually I got up to use the bathroom. While I was in there I realized just how hard I had gotten while watching my girlfriend on a date.

As I finished up in the restroom I heard the music start to pump. I had seen a DJ setting up and I guessed it was time for the bar to turn into a club. As I walked out I saw Lauren and her date still at the table. By now the bar had gotten pretty busy and I was in need of another beer. While I waited I lost sight of Lauren and by the time I finally got my beer and turned back around I saw her leading her date to what was now a fairly busy dance floor.

As they get onto the dance floor she turned around to face him. She then raised her hands over her head and started to wiggle her body as he put his hands on her waist drawing her closer. I saw her body rub against his, her breasts pressing into his chest. He wrapped his arms around her back and I saw him push his hips forward into her. I just sat in shock and stared as my hardon raged in my jeans.

One of his hands slid down to her ass and I saw him grab it hard. I was almost expecting her to stop him there but she just smiled and kept dancing before turning around to grind her ass into him. I saw her bounce her waist up and down on him as he grabbed her hips and pulled her into what I’m sure was his hardon. For my part, I found myself idly rubbing my cock through my jeans.

I kept watching them dance, frozen, as I saw his hands explore her body. I saw one hand slide up and grab my girlfriends breasts through her dress. I saw her hand reach up, I thought she was about to stop him. Instead I saw her grab his hand and press it into her breast. There she was, encouraging some guy to grope her! Eventually I saw her turn back around to face him. It seemed like things were moving in slow motion as he leaned in to her. She smiled at him, looking him in the eyes. She leaned forward and their lips touched. She opened her lips and his tongue slid into her mouth.

They pulled each other closer, grinding their bodies against each other as they made out. The tempo of the music was picking up and so were their bodies. They kissed more deeply and their arms, wrapped around their backs, pulled each other closer. I saw one of his hands slide down, grabbing her ass again and in response she slid her hand between their bodies and down to his pants, groping his bulging cock. Encouraged, he moved his hand below her ass and I knew he was rubbing her pussy through the dress material. I saw her holding onto him for stability as she moaned in pleasure.

Things were starting to get out of hand and I was scrambling for a way to intervene without her knowing I was there. I reached for my phone and texted her, ‘Hey, how’s the date going? You coming over soon?’ Luckily she seemed to feel the phone vibrate through the little purse she had on her shoulder because when there was a lull in the music she pulled it out and checked it. I saw her lean in and say something into her date’s ear. They talked for a second before she started typing into her phone. My phone buzzed, ‘We are just finishing up, he offered to take me home but I’ll give him your address. I’ll be over in half an hour.’

I breathed a sigh of relief, glad her ‘coffee date’ was coming to a close. However, I live really close to the nightlife area so half an hour seemed odd. I expected them to keep dancing to pass the rest of the time but they turned to head out. I followed them as they walked down a block before getting into a car. Scared of being found out, I ran to my apartment. Like I said, I live really close by and with all of the friday night traffic I knew I could make it there before they did.

As I got to my apartment building’s door I turned around and saw a pair of headlights coming down the street. Realizing it was his car I quickly went inside and ran up to my apartment where I had a window overlooking the street. I got to the window just in time to see him turn down the alleyway. Pausing for a moment to think that was odd, I turned and hurried to my bedroom. From my bedroom window I could see a little bit of the alleyway, just enough to see them pass from view. My mind was running a million miles an hour. Why didn’t she get dropped off at the door? What were they going to do in the car? I should stop for a second to say that I was a physics major in undergrad and as such had taken some astronomy classes and had a pair of nice binoculars I used on clear nights. I saw them sitting on my bookshelf and grabbed them before crawling out of my bedroom window onto the fire escape.

I headed up a level to a landing where I had a full view of the alleyway, and there was the car, giving me a head on view right into the passenger compartment. I put the binoculars to my eyes just in time to see her unbuckle her seat belt and lean in to kiss him. They hungrily devoured each other as his hands pulled her closer and her hands explored his chest. With dread I saw her slide her hand down. I thought she was going to grop him through his trousers again but she stopped at his belt and started to unbuckle it. She unzipped his pants and fished her hand inside before pulling out his hard cock. There was my girlfriend, whom I was crazy for, with her hands wrapped around some guys cock. I saw her grin at him as she started stroking him.

I knew that look on her face. She loves the feeling of power she gets when she strokes a guy. She loves how it drives him crazy, makes him hunger for more. She loves that she gets to control how she pleasures him. Whether to jerk him off hard and fast till he pushes his hips up towards her, getting ready to cum, or to stroke him slowly and sensuously, making him ache for release. I could see how much she was enjoying her position. But it seemed like her date was tired of her being in control. I saw him slide his hand up from her ass to the back of her head. Immediately I knew exactly what he wanted.

She knew it too and that’s why i expected the date to end there. But instead of getting out of the car, she let him guide her head down. I saw her lick her lips in anticipation as her face approached his cock. Slowly I saw her open her mouth and his cock disappear. She let him push her down deep before she started bobbing up and down on his cock. As she sucked him she grabbed the base of his cock with her hand moving it in time with her mouth. He rolled his head back in pleasure as she serviced him. I saw him pushing her deeper and she obliged. Spit drooled from her mouth as she went up and down on his shaft. He reached down with his other hand and grabbed her breasts. In response she slid the shoulder straps off revealing her tits for him. He pulled on her nipples and I know how much she loves that.

She kept sucking him deeper giving him one of the messiest blowjobs I have ever seen. He was in heaven, using my girlfriend’s throat. He started bucking his hips, his mouth open, I think we all knew what was about to happen. I saw him lurch forward and Lauren sucked him deep. After a couple seconds she pulled off of him in time for him to send spurts of cum onto her face and tits. She kept milking the last of his cum out of him with her hand before bending back down to lick his tip clean. I just sat there watching dumbfounded.

Finally I could see her sit back up and exchange some words with him. All the while his cum dripped from her face and chest onto the dress. She apparently noticed and reached under her dress to pull off her thong. Lauren used it to wipe her face clean and then pulled the dress back up, not bothering to clean the strangers cum off of her tits. She smiled and handed him her thong before she got out of the car.

I snapped back into reality as I realized she was on her way into my apartment. I ran back down the fire escape as quietly as I could. I got back into my bedroom and stripped off my clothes before hopping into bed pretending to be asleep. I lay there naked, my hardon raging as I heard her come in. I listened to the rustle of clothes before my bedroom door opened and she walked in naked. She slid into bed next to me and we lay there facing each other.

“How was your night?” I asked quietly

“It was good, just a boring date,” she said and I swear I could smell something on her breath. “I missed you,” she finished.

“I missed you too,” I said even though my mind was reeling. It just seemed like the natural thing to say.

“I can tell,” was her response as she reached down to rub my cock.

I moaned in response as I felt her soft hands on my hard member.

In a breathy voice she said, “kiss me,” as she stroked me.

I hesitated for a second before leaning in and kissing her deeply. The pleasure and feeling of it was strong enough to make me not care about what I’d seen. She leaned into me, rolling me onto my back as she straddled me. I reached up grabbing her breasts. They were sticky in my hands but before I could say anything I felt the warm wetness of her pussy being ground against my shaft. The feeling was ecstasy and before long my cock was coated in her juices. She reached down and guided my cock into her. Normally Lauren prefers more foreplay but apparently tonight she didn’t need it. My cock slid easily into her and she started fucking me relentlessly.

I grabbed her breasts again pulling on them as she fucked me. Images of her on the dance floor and in the car flashed through my head. It was too much and I felt that familiar swelling in my balls. Luckily Lauren was also on the edge from the evening. I felt her pussy flooding with juices, her moans increasing. I started to feel her pussy clamping down on my cock and it was too much for me, I moaned as I came hard, filling her pussy with my cum. I think that was the hardest I’d cum in a long time. I finally collapsed back on the bed, confused, but so satisfied.

When I woke up the next day Lauren was gone. I remembered she had said something about a morning meeting. Whatever, I needed some time to think. I just lay in bed remembering everything I saw. I couldn’t help getting hard and I jacked off picturing her leaning in and kissing that guy on the dance floor. I came thinking about her sucking him in the car. Even though it made me hard, I was still pissed. She texted me later on that day to see what was up but I didn’t respond. In fact, I didn’t text her back all week.

The next Friday night she texted me asking if I was still going to Dave’s. Dave was a mutual friend of ours and was throwing a house party that night. I had already told Dave that I was going to go so I felt like I had to show up. I decided not to tell Lauren and ignored her text message, hoping she wouldn’t be there.

When I got to the party I realized just how big of a blow out Dave was throwing. There were a ton of people there, apparently he had told everyone invited to bring whomever they wanted. People apparently delivered, it seemed like more of a college frat party than a party for twenty-something year olds. I squeezed my way through the crowd of strangers and found a group of my friends hanging out in one of the rooms. I only shrugged when they asked where Lauren was but I eagerly accepted a beer and the periodic shots they brought around.

Of course after a few shots it was time for me to use the restroom. The upstairs one had a hopeless line so I headed down to the basement. As I meandered my way through some crowded rooms I caught site of Lauren sitting on a couch talking to some guy. She was wearing this pink blouse that showed off just enough cleavage to leave everyone wanting more. Below that she had on a silver glittering skirt that threatened to show what she was wearing underneath. She looked liked she was seeking attention and from the look on that guy’s face, she was getting it.

She sat there holding a red solo cup, giggling and playing with her hair while she talked to him. They kept exchanging flirty glances and I saw him repeatedly glancing down her top. For her part she was keeping her legs crossed but as she chatted she fidgeted with her legs and her knee kept bumping against his. Emboldened, he turned to face her as he started telling her something and rested his hand on her knee. She looked down at his hand there and bit her lip, pausing as if she was trying to make up her mind about something.

She glanced back up at him, listening to his story and smiled before uncrossing her legs. My cock jumped in my jeans as I saw my girlfriend give the green light to him, encouraging him to touch her somewhere that only I should get to touch. I saw his fingertips tracing little patterns on the inside of her leg. She closed her eyes for a second and I knew how much she was enjoying his attention. She was always so sensitive to light touches, especially on her thighs. Every time I teased her like that it would turn her on so much her pussy would be dripping wet by the time my hands made it up her legs. My cock throbbed as I imagined how wet her panties must be getting from this guy’s touches.

He kept sliding his hand higher and she obliged by opening her legs just enough to give him room to keep going. When he got to the hem of her skirt it seemed like she had enough. She put her hand on his to stop him and leaned in to say something into his ear. I watched starting to feel relieved, but it was shortlived. He said something back to her as he reached into his jacket to pull out a box of cigarettes. I guess he was asking her to go outside for a smoke because they both stood up and headed towards the stairs.

I was between them and the stairs and had to quickly slide around a corner so they would not see me. I tried to follow them but they had a head start and I quickly lost sight. As I got back to the ground floor I bumped into a few friends and had to humor them with a little bit of conversation before excusing myself to continue pushing through the crowds of people towards the back yard. I looked around on the porch and the bench Dave had put in under a tree but no sight of them. Finally I heard a moan coming from the side of the house.

I snuck over and there I saw my girlfriend in the shadows with her back against the building. Her blouse was completely open and he was grabbing at her breasts as they made out, their tongues deep in each others’ mouths. His jeans were unzipped and pushed down to his thighs. His cock was pressed up against my girlfriends stomach and she was stroking the whole length of his shaft.

I stood there, half hidden by a tree, taking it all in. The whole thing was too much for me and I couldn’t resist the urge to unzip my own pants and pull my cock out. I stood there in the darkness furiously stroking myself while my girlfriend cheated on me. I watched as he slid one of his hands down from her breasts. He grabbed the bottom of her skirt and pulled it up. He slid his hand all the way underneath and I saw her wiggle her hips as he pushed her red thong to her knees.

She rolled her head back in pleasure as he slid his hand back up to her bare, shaven pussy. She pulled him closer, jerking him harder as he fingered her. He leaned in, kissing her neck quickly finding out that it is one of her most sensitive spots. Her groans grew louder and she rolled her head to the side, her face turning towards me..

“Shit.” My stomach dropped as our eyes locked on to each other. She glanced down seeing my cock in my hand. I don’t think either of us knew what to do, we just stared at each other. It felt like eternity before I saw a faint smile on her lips as she started stroking the guy even harder. My eyes stayed locked on her, dumbfounded as the guy started jerking his hips, trying to get every bit of pleasure out of my girlfriend’s hand.

She knew exactly what she was doing and we stared at each other as we heard the guy moan. He bucked his hips towards her and long streams of cum sprayed from his cock onto my girlfriends tits, stomach and hand. She kept stroking him until she had every last drop. Finally she turned back to him and I could hear her whispering but couldn’t make out what she was saying. He pulled his jeans back on and I hid behind the tree as he walked back into the house, leaving my half naked girlfriend leaning against the wall, covered in his cum

Slowly, I walked over to her, my hard cock still out in the open. I didn’t know what to say and I don’t think she did either. Instead she grabbed my cock, I could feel the other guys cum on her hand, getting my dick wet as she stroked me. She pulled me towards her and I felt the cum on her breasts through my shirt. She kept pulling on my cock, pushing it down between her legs. I felt the soaking wetness of her cunt on my tip. My head reeled as I felt myself slide into her. I grabbed both her hands and held them over her head, pinning her to the wall. Our lips met and we made out, moaning into each others’ mouths.

I fucked her so hard, giving her everything that I had. I broke off the kiss and moved to her ear, biting the lobe. It was too much for her and she almost screamed. I felt her juices flooding over my cock. The entrance of her pussy contracted and I could feel her walls rubbing the underside of my cock. It was almost painful as I rammed into her while she came. It was too much for me and I slammed into her so hard I almost lifted her off her feet. I came deep inside her, filling her with my seed. I kept ramming into her until my balls were empty. Finally, I slid out of her, the exertion too much and I stumbled onto the grass. She slid down the wall and we sat there panting, staring at each other, my softening dick still pulsing as my cum leaked out of her cunt.

Eventually, without saying anything, we both stood back up, fixed our clothes and walked with each other down the alleyway to our respective cars. When I got home I saw her car parked outside my building. I found her waiting outside my door. We went inside, took off our clothes, and fell asleep in my bed.

Lauren and I never talked about that night at the party. I was too embarrassed to admit it turned me on to see her with another guy, and I think she didn’t want to talk about it thinking it would make me mad. We kept seeing each other and acting like everything was normal until a couple weeks later when we went on a long planned ski trip. For her, the main attraction was the après scene. So we got a hotel near the slopes that had a hot tub. We got back from a day of riding and decided to head for the tub. By now Lauren knew how much I enjoyed showing her off so I wasn’t surprised when she decided to wear one of her skimpy string bikinis. We got ready in our room with two queen beds (the place was sold out of king rooms), wrapped ourselves in bathrobes and headed for the tub, stopping at the bar to get some drinks.

The tub turned out to be pretty small but so far we were the only ones there. We hopped in and sat down next to each other. We hung out chatting about our day. I had gotten some great runs in and was feeling pretty charged. Our conversation started getting frisky and I was teasing Lauren by running my fingers up and down her thighs in just the way that I knows drives her crazy.

In return she put her hand in my lap and teased my growing hardon through my swimsuit. Emboldened, I reached my arm around her back drawing her closer to me. I let my hand slide down, running my fingers along the waist of her bikini bottoms. I let my fingers absentmindedly play with the knot holding her bottoms on. At this point in our relationship Lauren knew me too well and had a pretty good idea of what I wanted to do. She shot me a look that said ‘don’t you dare’ but really meant ‘you’re turning me on.’

I obliged and grabbed onto the end of the knot and pulled, feeling satisfied as the knot came undone. Lauren giggled at me and rewarded me by wrapping her fingers around the bulge in my swimsuit. I pulled my arm from behind my back and placed my hand next to me on her thigh. I slid my hand and up and pulled the triangle of bikini material to the side. With the bubbles from the hot tub it was impossible to see anything but below the bubbles, her pussy was totally exposed to my hand. I wasted no time in pushing my fingers between her lips till I found her clit. She arched her back and closed her eyes as she felt my fingertip pressing against her sensitive part.

I swear I only had her like that for a few seconds before we were cruelly disturbed by three people coming out to join us in the tub. Lauren instinctively closed her legs, leaving my hand wedged between her thighs. From the looks of it, the new folks were college kids, two guys and a girl. We tried to act normal and said hi as they sat down. The girl and one of the guys sat down across from us in the tub which only left room for the remaining guy right next to Lauren. As he sat down I’m sure that both Lauren and I were glad for the foam covering her.

The girl was young, probably 20 and I would say she was pretty hot but that’s not the kind of thing you’re supposed to think about when you have a girlfriend. Besides, from the way her and that other guy were sitting I’d say she was taken. We all went around and made introductions. It turns out I was right, the two guys were college buddies and the chick was the guy’s girlfriend.

When it was our turn for introductions I started to speak but Lauren interrupted me, “Oh, we are friends from grad school.”

Friends? Last time I checked we were dating, in fact this weekend was supposed to be a chance for us to spend some time together, y’know fucking. But Lauren gave my cock a squeeze and I decided to go along with it. I was on edge wondering where this was going and did not participate much in the conversation. Lauren more than made up for it. She was apparently in an outgoing mood and seemed to really hit it off with our new friends. As we talked our drinks got low and I volunteered to make the cold run back to the bar. Luckily the cold air helped me conceal my hardon and I came back with two beers for Lauren and I and five shots to share.

When I returned I found that the couple had left, leaving my girlfriend and the guy alone in the tub. I felt a stirring in my crotch as I walked up from behind them. As I hopped in the remaining guy informed me that his friends had gone to their room to shower.

Lauren smiled, “guess we will have to do all those shots ourselves,” she said as she grabbed two and handed one to the guy. They didn’t wait for me to finish sitting down before doing them.

As I sat down I noticed that Lauren wasn’t sitting with her legs tightly closed anymore. I put my hand on the inside of her knee and starting sliding it up along her thigh, eager to see if she had left her bikini bottom untied. I only got about halfway before she turned to smile at me and took my hand and removed it from her thigh before placing it on my crotch. She held onto my hand and rubbed my growing bulge with both our hands. As I looked at her I noticed how flushed her face was looking. Whatever was going on, she seemed to be enjoying it.

As we sat there the conversation seemed to be dying down, but I could feel Lauren squirming a little in her seat. They both decided to do two more of the shots and I got to watch Lauren giggle at the taste. By now I had a pretty good idea what was going on, especially as I looked over and saw the guys arm slowly moving. As I watched I could see Lauren bite her lip and the realization of what was happening caused my cock to swell. I sat there dumbfounded while my girlfriend rubbed my cock at the same time that some guy had his hand on her pussy.

Still, I wasn’t ready for her to say to me, “I told Brian about our plan to go back to our room and watch a movie. He said he doesn’t have any plans so I invited him to join us. You don’t mind do you?”

Wow, inviting this guy up to our room for a movie? The thought of it made me lightheaded and I felt like my cock was going to burst out of my swimsuit.

All I could do was nod and mutter, “Yeah, sure thing.” Lauren smiled and stood up, grabbing the side of her still untied bikini bottoms. She quickly tied them up before reaching for the last shot and downing it. We all grabbed our bathrobes and headed up to our room.

When we got upstairs Lauren flipped on the tv to some movie or other and then said to me, “Brian and I can watch from my bed that way you can have your bed to yourself.” I nodded in agreement and sat down on one of the beds. Lauren turned out the lights and the two of them climbed into bed together, getting under the covers.

I lay there and tried to concentrate on the movie but it wasn’t long before I could hear the sounds of sheets and clothes moving around. I slid my hand into my swimsuit as a soft moan escaped from Lauren’s lips. I glanced over and saw Lauren lying on her back, the covers had fallen down and I could see her robe was completely open, her breasts just covered by her bikini top. The covers came up to her stomach and on the other side of her was Brian, on his side, a hand below the covers. The motion of the sheets under the soft glow of the TV left no doubt as to where his hand was.

Not wanting to miss anything I turned onto my side to face them and pretended to be asleep. Lauren giggled and I heard her whisper something to Brian and a second later I saw her bikini bottoms fall onto the floor between us.

I heard her say to him, “I think he’s asleep,” and as they looked over I closed my eyes to play the part. A second later I heard more rustling and I looked over to see Lauren straddling this guy. The covers had now fallen down and weren’t hiding anything. I watched as she slid her robe off before reaching behind herself to untie the bikini top. Just like that, my girlfriend was completely naked on top of some guy’s body. She sat there, rubbing her pussy against his swimsuit, teasing her breasts with her hands while he looked on. For my part, I pulled my suit down and started to jerk myself. I was so turned on watching this I felt like I was ready to cum.

As I stroked myself, Lauren slid lower on him, pushing his bathrobe open. She kneeled in front of him. I had images of her sucking that guy in the car as she tugged down on his swimsuit until his hard cock popped out. She tucked her hair behind her ear in that sexy yet innocent way that always drove me crazy. She leaned down and parted her lips for his cock, taking it into her mouth. My girlfriend bobbed her head up and down on his cock as he moaned. He lay there while she used one of her hands to rub his balls and the other to pump his shaft as she sucked on the tip. I jerked myself as hard as I dared ready for him to cover her face in his cum just like the last guy did. But Lauren had other ideas. She raised her head up and smiled at him as she continued to jerk him.

I saw her slowly crawling back up to him. I watched in horror not thinking that she would actually do what it seemed like she was about to do. She straddled his cock and I saw her sliding it up and down her pussy lips. I couldn’t tell if she was teasing him or planning to go through with it. It’s one thing to see your girlfriend suck a guy’s cock but to watch them actually fuck?

Apparently Brian decided he’d had enough of the teasing. He grabbed my girlfriend’s waist and pulled her forward, with a gasp from her, his cock slid into her pussy. She looked down almost in surprise at his cock deep in her. I thought she was about to jump off of it, I wanted her to. Instead she smiled at him, moaned, put her hands on his chest and started riding him. I wanted to be angry at her, I wanted to stop them, but instead I felt a tightening in my balls. She slid up and down on his cock, her boobs bouncing. He reached up and grabbed them, pulling on them as she fucked him.

“Oh yes, fuck me” she moaned as she ground into him. He grunted, enjoying my girlfriends pussy. They were too preoccupied to notice me furiously jacking off. I saw the look on his face as his cock invaded my girlfriend, the way she looked as she rode him, the sound of her soaking wet pussy, her lust filled eyes. I watched, unable to look away until I felt my balls seize and warm cum shot all over my hand and the sheets. I came so hard, it felt like it lasted forever.

As my head cleared I watched my girlfriend still fucking him. I heard him groaning and she moaned, “Yes, do it! Fill me!” I saw him almost sit up and his response told me he was fulfilling her request. She continued to gyrate her hips on him, milking him for the last of it before she collapsed on top of him.

She rolled off of him, lying on her back. I heard them whispering back and forth for a minute until he stood up, put his swimsuit and bathrobe back on, and walked out. As we heard the door close Lauren slid into bed next to me. As her body touched the pool of cum I’d left there she said, “I was worried you’d be mad, but I guess you enjoyed it.”

She rolled on top of me, and lay there, her pussy resting above my soft cock.
