This happened a long time ago, the names and details are fuzzy. I'm not sure if it's rape, but it definitely wasn't consensual.
Me (~20 y/o) and two friends (A, B) are chilling at A's place, drinking beers, playing beer bong, occasionally taking a few vapes, and just generally chilling. Friend B states that he has some friends coming over, including some girls. Friend A and I both say, "Cool", and continue chilling.
After about half an hour, friend B's friends arrive; two dudes and two girls. One of the guys and the girls are in a relationship; they spent most of the night together. The other guy was in a relationship with a girl out of town. The other girl, we'll call her X, was single and not happy about it. B's friends are generally cool, kinda weird but nice people that are easy to get along with. X, however, was a little too friendly. She started eying me shortly after arriving, and was obnoxiously persistent in her attempts to sit next to me and interact with me. Now, I'm not opposed to general chit-chat, but when you ask me dumb questions ad nauseum so that I can't reasonably communicate with anyone else there. I'm trying my hardest to avoid X, while being as polite as possible about it, but she won't leave me alone or be more than 10 feet away from me.
As the night progresses, things wind down. Friend B is passed out, the couple left, and Friend A and B's remaining male friend are having friendly drunk talk. For the first time the whole night, I don't know where X is. I'm pretty hammered myself, and it's about 2 am, so I decide to call it a night. I distinctly remember walking into the guest bedroom to see Friend B sleeping on a small couch next to an empty bed. I recall snickering at him for choosing the more uncomfortable of the two options, then falling asleep on the bed.
I don't know what time it was, but I woke up to a bottomless X on top of me, clumsily grasping at my zipper and my penis. I tried to say "No", and "Get off", but I think I just made an illegible drunken mumble. I tried to push her off, but was too drunk-tired and weak. She told me to be quiet and enjoy it. I was in that groggy mental-space from waking up from a deep sleep, and couldn't think straight or decide what to do.
I never saw her again after that night. She ended up having a baby about a year or so later (not mine), but Friend A joked that it was mine when he first told me. I shit a brick and almost puked before telling him what she did. I told him that I was confused, scared, partially immobile, and in a drunken sleepy stupor, mumbling "No" and trying to push her off. He made a few jokes about it, then told me that X had said I "wanted it" because I was "flirting with her all night".
