My wife has been having an affair (that's what I call it, but she just calls it sex) with the husband of one of her friends for years. On a somewhat regular basis he is able to get into town and he and my wife get a room at a hotel and spend a night or two copulating. I help cover for him so they can fuck in peace without his wife catching on. And they spend every second connected at the crotches. I'm surprised he has never impregnated her as much semen as he has pumped into my wifes bare naked slit.
