I knew for ages my mate freeballed, and I used to love it when he would walk by me in his sagging jeans I would get a good look at his peachy ass and top of his pubic mount. We started sharing a flat and he'd often walk round in the buff. One time I was lying on the sofa and I couldn't resist as he walked past I slapped ass. He was furious, he started shouting and stuff, I told him if he didn't like it then he should stop walking starkers, he jumped on top of me and said that we will see if how I liked it, he pulled my shorts and boxers down and slapped my ass, I rolled over so we were both facing each other naked, we fought a bit, and we fell off the sofa and he landed on top of me, I don't no why but we groped each other and played for hours with each other. First and Best experience
