CRASS! My flatmate FUCKED ME IN THE ASS!

I wonder if that was a good idea! My flatmate really wanted to fuck me in the ASS because his girlfriend wouldn’t let him. But can I just do it like that? In any case, his horny cock thought it was possible and he was able to convince me pretty quickly. I finally had a thick cock in my tight arsehole again! I wonder if his girlfriend will ever find out! Or do you think that was too blatant?
