I (23M) accidently had a threesome (FFM)
This happened a couple of years ago, maybe when I was 20? I had been dating this girl (19F) for about 3 weeks, it was an open relationship agreement between us both. She lived in an apartment with another girl (also 19F) who I, admittedly, was very attracted to. They were both brunette with great figures and loved socializing.
One night, we had a small party in their apartment with boardgames, drinks, snacks, etc. We were relaxing, having fun, playing this drinking game that made you admit dirty things. One of the cards I read said something about a fantasy threesome. Me, having had some drinks while still being logical said my then gf and her roommate. I realised what I said, when I locked eyes with the roommate who then looked at my gf and turned bright red.
Shortly after the night started to wind down, I knew I was in trouble. My gf pulled me aside and started to say how she understood, but probably not to say that in front of her because she was quite shy. I apologized and just said that it made sense in my mind because of how often I'd be over at their apartment anyway, I wasn't really thinking about it.
Later that night, once everyone left, being in a new relationship we had sex often, so we decided why not. Plus, it was the first night I had decided to stay in her apartment with her. Before we got started, we had to talk about what I had said before again. She stated that she had obviously talked to her roommate about me before, so she knew a lot about me already. She had explained our arrangement, my kinks, pretty much everything I had no idea women talked about with eachother. But she also said she didn't blame me because if she were to have a threesome with anyone she agreed it would be her, so I felt better about my answer before.
She dropped to her knees at the foot of the bed, tied her hair up and told me to lay back. So of course, I agreed. I slipped my shirt off and she unbuckled my belt before grabbing my cock out of my pants and spitting on it, making me hard, and deepthroating me like she knew I loved. That's when we heard a quick knock on the door and her roommate barged in. She was used to doing this because it was normally just the two girls there.
She immediately realised what was happening, blushed and closed the door. My gf went after her in embarrassment. They were gone for a while, leaving me with a wet, now cold, slightly placid cock, when they returned.... BOTH of them. I was confused why they had both come back. Then my gf opened her mouth and said they had talked.
Apparently, after my gf chased down the roommate, the roommate said "holy shit that thing is huge" while laughing and apologizing about catching us in the act. My gf then apologized to her about the whole threesome thing, but also defended me by saying if anyone it'd be her for her as well. Then she made a bold move and said "y'know, I could use some help". Which explains why they were both there now.
From telling me this, I had already gotten hard at the thought of it. They both noticed and smiled, my gf lead by dropping to her knees and starting to lick me again. The roommate stood there, kind of awkward and unsure of what to do, so my gf grabbed her hand and pulled her down to show her what to do. They both began taking both sides of my cock in their mouth, licking it, making it sloppy.
Then my gf told her roommate to take her clothes off, she hesitated but I think was getting too horny to care anymore. I hadn't seen her naked before, so I of course watched, both of us watched her get undressed. She was so much sexier than I though, whenever I had seen her she was wearing baggy clothes. She was so curvy and had a very similar body shape to my gf.
My gf then instructed her to sit on my face. She did, she planted herself over me, her pussy was so wet and juicy. I practically drowned there and I would've been happy with that. My gf then stopped licking my cock and decided she wanted to ride it, so she sat on my thighs, ready to ride me.
I heard them both kissing and playing with eachothers boobs. My gf had now slid my cock inside her, she was also wetter than usual which helped me slide in. They both moaned while kissing and playing with eachother. They both giggled at the thought of what they were doing.
After a while of being ridden and eating the roommate out, they talked about switching. The roommate hadn't had much experience and definitely hadn't taken something as large as me before. My gf managed to somehow convince her to give it a try. So she laid down on the bed, my gf grabbed her legs and held them in the air above her shoulder for her while suffocating her with her now gaped pussy.
The roommate was now eating my gf out while I was teasing her pussy with my cock, running it up and down her clit and teasing her hole. She was getting so wet from this, which was exactly what I needed. I proceeded to slowly insert the tip of my cock in, she immediately grabbed the sheets to brace herself. I slowly slide it deeper, when I got to a certain point she stopped eating my gf out to loudly moan.
My gf then got off of her face so they could both watch my actions. The roommate stared in disbelief at the cock she was taking, I had still barely put any in but she looked in shock up at me. I pulled out a bit and started to slowly thrust in hopes that she would be able to take a bit deeper.
My gf was next to her, encouraging her, and telling her she was doing a good job. Just then I thrusted a bit deeper and felt her get wetter, her natural instinct to provide more lube. At least so I thought, I pulled back out to see her juices cause it turned me on and she squirted. My gf quickly put her face down to suck up the juices. She screamed as she squirted everywhere.
I watched as she proceeded to squirt and orgasm from my gf sucking her clit. This turned me on so much, so I decided to switch back to my gfs pussy while she was sucked her clit and pounded her. The roommate watches me pound my gf and bites her lip while still being eating out. I felt close to cumming so told them both to drop to their knees.
They obey and drop down in front of my, making out with eachother and squeezing their tits together for me to cum onto. My gf then grabs her roommate's hand and helps guide her to jerk me off. I feel it coming, they both turned to face me and open their mouths. I shot so much cum into both of their mouths, all over their faces and tits. They proceeded to lick eachother clean and make out.
They both went to go shower together, probably chat about what just happened, and talk about what that may now meant in terms of having sex together. All I know is that the following 4 months I spent in that relationship, we had threesomes at least once a week and it felt incredible.
