I have spent a lot of time with couples over the years, where the husband wants to watch his wife being fucked. Usually they sit or stand there (mostly naked) and jerk off watching us, sometimes they want to get really close and see everything, I usually don't let them touch during the sex, when they do, it goes beyond being watched. Anyway, if she is not distracted by him, the wife usually loves it for some reason, and I do too! Also I have had oral and fucked for audiences at sex parties and on nude beaches (usually around dusk). It's great when the guys are jerking off watching, and people are cheering you on. It's wonderful for the ego.
