My floormate has a crush on a girl in, I fucked her in his bed all weekend

In college I had a floormate two doors down who was obsessed with a girl (we'll call her K) and floor beneath us. They had gone to high school together back home and he had crushed on her for years, he would do anything she asked of him, free weed, money, etc. He had a decent room and a nice AC unit a lot of us envied.

I had seen K around plenty of times and she was always very flirty with me, which bothered him a lot. She had heard I was hung ( pics on profile ) from dorm talk and was always making little jokes about it around me. She was 5'3" with a beautiful pair of tits, big pouty lips, a nice figure, brown hair and big eyes.

So one weekend he went out of town to visit family back home and K asked for his room key to use his AC unit. It was a hot, California weekend and she wanted to be able to cool off. He of course gave it no questions asked.

Later that night K knocked on my door and asked me if I wanted to watch a movie in his room because she was a little lonely. 15 minutes later we were in his bed making out. She ended up giving me a sloppy blowjob and letting me fuck her all weekend in his nice, temperature controlled room. We left his sheets sticky and covered in sweat and cum.

After that K became a regular FWB and I would fuck her 3-4 times a week wherever I could. My room, the showers, the common room at night. One time I fucked her up against his door at 2am while covering her mouth. She would talk shit about him during sex and make fun of his small dick (they had hooked up once before) She even pierced her nipples for me about a month in to our fun.

He would always complain to her about having to hear her moans and dirty talk through the thin dorm walls. About a year after living there they both dropped out and moved back home where they started dating. They've been together five years, but he never found out how I fucked and filled his gf in his bed for a weekend in college then made him clean up the mess.
