Str8 roommate

My best friend who looked like Matthew Broderick (Ferris Bueller) was straight and I was gay. We worked together and lived together in an apt. He used to bring over women and would be having sex in the adjoining room and it drove me nuts. He had told me he was fine with me being gay as long as I didn't come on to him. He finally got married and moved out and I was his best man. One night he was at my place and we were partying and horny...He asked if I had any porn magazines, this was back in the 80's. I told him I thought I may have a Penthouse but he said gay stuff would be fine. He knew I wore sexy underwear colored nylon with no fly. He asked me if I would take some pics of him wearing some of mine...I gave him some thongs and bikinis one silk and one see thru red nylon thong. I was getting close ups of him in those and he was getting hard...he was hung well. Finally I gave in, and put the camera down and began licking him through the red sheer thong...I pulled his big cock out and sucked him until he filled my throat with his hot load.
