I just graduated from college in the spring so this was probably February. I’d known my roommate and his gf since sophomore year and they’d been together since high school.
This girl would always get really handsy when she was drunk and there’d been a couple nights before this where we would be alone and I’d feel her up while talking.
Finally, one night while her younger brother was visiting, her bf left the party we were at early and was asleep by the time we got back. Her brother fell asleep on the couch as soon as we got back but she was still really talkative so we went and sat on my bed.
As she talked I put my arm around her and slowly moved my hand down the top of her dress. She kept talking so I kept going. With my other hand I was moving my way up her thigh. Finally she asked if she could kiss me and we started making out. I stood up and moved between her legs and we continued to kiss while I slid her dress up above her waist.
She undid my pants as I removed her thong and after a little teasing I thrust my cock all the way inside her. She moaned really loud and we both froze for a minute thinking we’d been too loud and her bf or brother had heard us. I slowly started back up again and she laid back and held her legs spread wide. After a while I pulled out and laid down on the bed. She took her dress all the way off and straddled me on the bed. Her ass felt amazing to squeeze and slap and after a minute she got insanely tight as she orgasmed on my cock. I kept fucking and as I got close I whispered that was gonna cum and she started moving up and down faster. Finally I pushed down on her ass and held her there as I came deep inside her. We stayed like that for a couple minutes catching our breath and talking and then she walked out naked carrying her clothes and walked right into her bf’s room.
The next morning once everyone woke up, she started making a big deal about how her and her bf had fucked so hard that she must’ve passed out right after because she usually doesn’t go to sleep naked. She said all this because she was worried that her bf would be suspicious about her being naked in bed.
We never actually talked about what happened but they’re still together so I guess he never found out.
