Kama Sutra le dio ideas

Kama Sutra gave my gf a few depraved ideas and she told me she wanted to try something new in sex. Okay, I had this crazy fantasy about her fucking another guy and me just watching so close I could touch her, and now it's a perfect chance to make it happen. I saw her giving one of my friend's looks and I know she wouldn't mind having sex with him, so here we are, me watching and her shamelessly fucking this dude and enjoying every moment of it.
