Your wife is gorgeous. If I lived closer I would love some of that action.
To answer your question, I stunt cock for my best friend. It started one night when I was at their house & we wound up playing strip poker. By the time I had to take off my underwear she was only wearing panties. The site of her had given me a raging hard-on & she was fixated on it when I took it out. She kept joking around, or so I thought, about how she wanted to take me upstairs. Over the next few weeks she apparently bugged my friend about it so much that he started bugging me about it. I didn't want to ruin our friendship, but I eventually gave in. We've done it quite a few times now & he's even joined in a couple times.
