Kama Sutra gave my gf several depraved ideas and she told me she wanted to try something new in sex. Okay, I had this naughty wish about her fucking another guy and me just observing so close I could touch her, and now it's a ideal chance to make it happen. I saw her giving one of my homies looks and I know she wouldn't mind having fuck-a-thon with him, so here we are, me observing and her shamelessly fucking this dude and luving every moment of it.
