My best friend screwed my wife several time a week but i did not get to watch often The times I did watch I it was very humbling. His cock was a few inches longer than mine and much thicker, the head was larger than the shaft and when he was hard it would stick almost straight up. I liked watching his position himself between her legs and place his cock at the entrance to her pussy without touching his cock. Once her felt her hole he would gently push his cock until the head disappeared and would began a slow rhythm until he was all the way inside. I loved to think about the reality of this moment, the head of my best friends cock was literally deeper in my wife than I had ever been. I would also wonder how that big head felt so deep inside. The only time I saw her orgasm was when she was with someone other than me and he was capable of bringing her to multiply orgasms. I never touched her when she was with another guy I just sat in a chair and watched. He never used a condom and it was a big thrill for me when I would hear him moan shortly before he would start to deposit his semen deep into her belly , to me this was his acknowledge to both me and her that he was the superior.
