I needed the money and did not want to chicken out. I stood back up and turned around. He started rubbing my pregnant belly and leaned in to suck my tits. I reached over and undid his belt and zipper. His pants fell to the floor and I rubbed his cock through his boxers. I was really getting wet by then, knowing we could be interrupted, I was.

It stimulates his prostrate. It makes him cum rivers. Some women aren't necessarily BI curious they just want to fuck a women once or twice. Just.
