TBH it looks nothing like a rape to me, the guy is most likely a hooker (not that hookers aren't raped all the time, because they are and it's a scandal because normally nothing is done about it even if it gets reported) and I've met plenty of hookers who need to be blind drunk to work, he was fully consenting by the looks of it and it looked like he was enjoying himself at various points. The whole thing was probably staged from start to finish, even the practical joke stuff at the end seems like something they probably agreed to before hand.
