[MFF] I fucked my girlfriends sister, when she found out, we had a threesome

Okay so first thing I want to address is the last post. Yes it is real and yes I did post it on another page and slightly edit it to try and get some trans interested. We like trans girls so what can I say.

Secondly, I’m back with the second part of this story.

So as you know, my girlfriends sister and I ended up fucking kinda out of the blue. We tried to keep it under wraps to prevent my girlfriend from knowing, unfortunately but also fortunately that ended up only lasting for so long. Here’s how that when down.

About 3-4 weeks after her sister and I had sex, she came over one Friday night at around 6 to drink with me and my girlfriend. Everything was going fine and nothing seemed to be out of the ordinary. My girlfriend and her sister aren’t the closest but just as we were, when the alcohol starts flowing, everyone becomes best friends. They ended up drinking ALOT more than I did. I was pretty much glued to my phone the whole night with work stuff so I was pacing myself. A couple hours go by and we decide to head inside and get ready to call it a night. But, as it usually goes, they decided to stay up and kept drinking. I was absolutely beat so I decided I wanted to head to bed. I told my girlfriend I was going to head to bed. I go walk up the stairs and turn into my bedroom. I go through my nightly routine (I.e. brush my teeth, change, take my contacts out) and as I sat down on my bed I realized that I had left my phone downstairs. I walk downstairs and as I turn the corner into the kitchen, I can hear my girlfriend and Jenna talking about something. They were almost whispering so I figured it was something I didn’t need to know. I didn’t care so I told her “Don’t mind me I’m just forgot my phone” I grabbed my phone and started to walk back toward the stairs. My girlfriend said “Hey babe, come here for a second.” I turned around and walked back “Whats up?” So we were talking about some stuff and wanted to get your input. “Okay sure” I said as I sat down on one of the barstools. My girlfriend said “Well don’t feel weird or anything…..just answer as you normally would…..it’s just us two here……and I won’t feel any certain way or anything……” she couldn’t seem to spit it out so Jenna blurted out “What’s the best sex you’ve had?” My face got red and I froze for a minute as I was put in quite the predicament. “Uh I’d rather not answer that” I said trying not to get involved. “Come on, we’ll tell you if you tell us.” Jenna said. “You first” I said. My girlfriend started. I’m not sure if she was serious or if she was just trying not to mess with my pride but she told a story about when I fucked her a week after we started dating and we had not had sex in a month or so. I went next and basically just said that that time with my girlfriend was the best.

Then Jenna went. When I say my heart was beating out of my chest, I’m honestly surprised that you couldn’t see my neck pulsating from my heartbeat. My worst fear had come true too. She began describing us having sex. I sat and listened and remembered. I kept thinking about how crazy hot it was and how the way she was telling the story was such a turn on. I happened to glance at my girlfriend and I could tell she was a little suspicious given the details that Jenna was giving but before she could finish, Jenna looked at my girlfriend and they laughed. “What? What’s so funny?” I said confused. “Uh, did you get a little excited?” I looked down and not only was I bulging out through my pajama pants, but I was leaking precum all over the inside of my pants. I quickly tried to cover up and apologized profusely. I noticed Jenna was biting her lip and couldn’t stop staring. My girlfriend caught on to that and she started looking back and forth and Jenna and me. I think this is when she put 2 and 2 together and realized that the story Jenna had been telling previously was of me and her. All of the sudden I hear “What the actual fuck!” Trying to play dumb I said “What? What’s wrong?” She looked at both of us and said “You!?!?” Jenna, realizing what had just happened and tried to play it off said “What are you talking about?” My girlfriend looked her dead in the eye and said “You fucked him?!” At this point I think Jenna was just kind of stuck at this point and finally admitted it “Look it was a one time thing it won’t happen again!”. My girlfriend ran upstairs angry while Jenna and I stayed downstairs and were glued to our spots because we were still shocked at what just happened. “I should probably go talk to her” I said as Jenna nodded her head. I walked upstairs and walked into our bedroom. She started asking me specific details about it and I gave up the info. There was no point in turning back or trying to deny anything now. She asked me where we did it. I kind of hesitated a bit and told her that it was actually right where we were sitting. I was a bit confused during this as she didn’t look upset or mad or anything just emotionless. But for whatever reason when I told her that we had fucked on this exact bed. She did a complete 180.

“Right here?” She asked placing her hand on the bed. “Yeah, actually here, there and a lot of this room” she chuckled and told me to wait a second. She turned around and a few seconds from then I heard the unmistakable sound of an iPhone text being sent. A few seconds later. She got a text message. Not gonna lie I was so scared at this point my mind was racing and irrational thoughts popped into my head. I had figured she was texting an ex or a guy friend to come fuck her and I was going to have to watch or she was texting her parents to ask if she could stay there for a while. As I’m sitting, thinking about why I did what I did. My girlfriend stood up in front of me and looked at me with this really sexy but kinda creepy deep gaze. She started kissing me. We made out for probably 20 seconds before I stopped her.

“What are you doing? Aren’t you pissed at me?” She started doing that walking finger thing up my leg and started talking to me kinda dirty. “Where as I am mad at you, when you told me about fucking Jenna on the end of the bed and how you fucked her, how you fucked her throat, how you came so hard. It made me, well, excited.” She said as she guided my hand underneath her leggings and onto her pussy. When I tell you I’ve never felt anyone this wet I mean it. It was like she took a whole bottle of lube and just dumped it on her pussy. It was amazing. “Lift up.” I did so hesitantly as she pulled my pants and underwear down around my ankles. My cock was hard as a rock at this point. She started rubbing my cock real slow, kissing and licking it every couple of strokes. All of the sudden there was a knock on the door. I instinctively tried to pull my pants up. “Wait, keep them down” she opened the door and there stood Jenna.

She was as shocked as I was. She stood in the doorway, mouth wide open, arms crossed staring at my cock. My girlfriend grabbed her buy the arm, dragged her in front of me, made her get down on her knees and said “I want you to show me how you sucked his cock.” “I told you I was sorry about this” Jenna said almost refusing to do anything. “It’s okay Jenna, I’m okay with it.” “Seriously?” Jenna said. My girlfriend grabbed her hand and again guided her hand to her pussy to feel the wetness. As soon as Jenna felt her, she went to work on me. Gagging on my cock just like before. “You like feeling his cock in the back of your throat?” My girlfriend asked as she was pushing Jennas head further down my cock. Jenna mumbles “mhmmmmm” as she gagged. Before long my girlfriend wanted to suck my cock and pulled Jenna off of me. “I know it’s a great cock but it’s still my cock” my girlfriend started sucking me. Now my girlfriend has never been able to really deepthroat but she sure gave a good blowjob. Jenna knelt there just watching. Every few seconds she’d look up at me in awe trying to figure out if this was really happening. I decided it was time to show her it was all reality.

I took my cock out of my girlfriends mouth and told Jenna to get on the bed, lay on her back with her head hanging off the bed and open up. She was shaking which was kinda hot so it only made me more horny. I put my cock in her mouth and throatfucked her until she cried. My girlfriend must’ve been impressed because I hear her say “Fuck, I didn’t know you could suck him like that.” My girlfriend then got on the bed and proceeded to eat Jenna out while I was fucking her throat. I could feel everytime Jenna was going to come, between the vibrations of her moans, her mouth sucking harder, and her shaking. It felt so fucking good. After a minute or two. My girlfriend stopped, pulled Jenna by her legs further onto the bed and placed her hips right over Jenna’s face. “She’s nice and wet for you” she said winking at me. I got into position and started teasing her with my cock. The moans were almost orgasmic between Jenna and my girlfriend. I started to push my cock inside Jenna and she let out a fucking hot moan. It wasn’t even damn near 10 thrusts before she squirted all over my cock. She’s not a stream squirter but more of a gusher but to watch and feel her pussy pulsate with every gush was everything I’d ever wanted.

We fucked for a few minutes in this position and then my girlfriend want to switch it up. Same position but my girlfriend was getting pounded now. After a while I hear Jenna let out a super loud and sexy moan. My girlfriend put a finger in her ass, I’m assuming to test her because within a minute my girlfriend wanted to switch it up again. Jenna laid on her back against the edge of the bed with her legs up near her chest and my girlfriend got on top of her so both of them were ready to receive me on the edge of the bed. I hear my girlfriend say “Fuck my ass baby.” “Gladly” I said grabbing some lube from the drawer and putting some on my cock and their pussies and asses. I fucked my girlfriends ass and I hear “Don’t forget about me” Jenna said. I started switching back and forth between Jenna and my girlfriend. Ass, pussy, pussy, ass. Rinse and repeat. My girlfriend and Jenna were both rubbing each others clits and I could feel and see them shaking, Building toward orgasms. I picked up the pace and started fucking Jenna in her ass and fingering my girlfriends ass. Hearing the moans intensify I knew they were about to cum so I fucked Jenna as hard as I could as I put two more fingers in to my girlfriends ass.

They came hard and at the same time. My girlfriend convulsing, Jenna squirting our her pussy as it leaked down to my cock. I quick switched back to Jenna’s pussy to feel her pulsating. At this point I was ready, I could feel my cock full of cum and needed to release. “Oh fuck I’m gonna come so fucking hard” I pulled out of Jenna and before I could say anything, I hear my girlfriend say “Wait, I wanna watch you cum in her pussy.” Jenna was on birth control so it wasn’t a big deal. My girlfriend put herself in between my legs and underneath my cock as I put one leg up on the bed to get deeper in Jenna. She apparently must’ve gotten the lube when I want paying attention too because the next thing I know, my girlfriend is in my ass massaging my prostate (don’t knock it until you try it) “Oh fuck I’m cumming!” “Cum for me baby, cum deep in my pussy!” I could feel my cock explode inside her balls deep. My girlfriend rubbing my prostate hard. I tend to have harder orgasms when I massage my prostate because I must’ve came for a solid 15 seconds. I pulled out of Jenna and watched the cum leak out of her as my girlfriend put my cock in her mouth and started blowing me in a way that I had never been blown before.

Between her mouth and the hand action it was absolutely orgasmic. With Jenna still on the bed watching my girlfriend suck my cock. I was in heaven. A few minutes later I found myself ready to cum again. Jenna could tell and wanted to watch this time. My girlfriend sucking the hell out of my cock took me out of her mouth and told Jenna to open up. She pushed Jenna’s head from behind just as I was ready to cum. Jenna had been good at deep throating but this was next level shit. I was balls deep in her throat and could see a slight throat bulge. “Fuck I’m gonna cum again” My girlfriend pushed on the back of her head as I came deep down her throat. Feeling her throat contracting on my cock was incredible. Listening to her throat making that “Glug glug” noise made it even better. I pulled out of her mouth and she took a deep deep breath. My girlfriend laughed and said “There, all you had to do was ask. Let’s do this again sometime.” We cleaned up and got ready for bed. We all ended up sleeping in the same bed that night and ever since then, my sex life is the best it’s ever been.

I hope you all enjoyed this.
