Worrying Story from Student

I was in my┬ástudents union and I was approached by three guys. One asked ‘will you fuck me?’ whilst the other three pretended I was on camera and the subject of a ‘student union’ prank. I told them to fuck off but they got more insistent and one placed his hand firmly on my shoulder. They claimed that I could watch myself and the sex videos on YouTube the next day- and that I couldn’t take a joke and was obviously too drunk.
