Sisters
My wife hates me playing with her nipples, she says hard nipples goes through her, yet i been fucking her sister for a few weeks, and she loves me to pull on them, flick them slap them, and chew an suck on them. My wife won't suck my dick, says that its not intended for that purpose, yet her sister sucks me like a vacuum. I will say though, that when i do get to fuck my wife, her cunt is so fucking tight, god-its so darn tight, that it outweighs everything else, her sister is a little slack but the foreplay is bang on.
Yeah, it's hard to find the perfect woman who is great at everything. That's why nature created such a wide variety of women, so we can enjoy all sorts of tasty treats. Monogamy is best suited to raising children, but is otherwise not a realistic aspect of human nature.
