Sex with my best friend

My best friend watched me doing my make-up the other day and got a really hard pipe. Apparently he's been watching me for a while and wanking his hard cock. He suddenly stood naked behind me and I felt his hard cock pressing against my arse. It was actually a hot number between us, but when it comes to fucking, I just can't say no. We fucked really horny in the bathroom and without a rubber. But he really didn't have to cum in my mouth.
