I've heard of an urban myth where a husband comes home from work early to find his wife in the bathroom with peanut butter smeared all over her pussy with the family dog just lapping away.

Personally, I think it falls into the realm of extreme kink, a variety of which I'm not partial to. Even though it's not particularly my cup of tea, as long as the dog's ok with it and it makes the lady happy, I say why not?
