My wife's best friend
I once had sex with my wife's best friend when she was passed out on pills and booze. She was so out of it, she didn't even react when I stuck my cock in her and started playing with her tits. I played with and sucked her tits while I fucked her for about 20 minutes. When it was time for me to let loose my load, I thought I better pull out and shoot my load on her, instead of in her, so she wouldn't wake up with sperm oozing out of her twat. After I shot my load on her, I grabbed a warm, wet washcloth and wiped her off. Neither she or my wife have any idea that I fucked her. I think about it every time we get together.
