I have found that my fiance absolutely loves it when he discovers that he's made me wet. It's really adorable when he makes this surprised face when he realizes that I have drenched my panties. He makes some sexy comment about how he's going to take advantage of it and he keeps his word.
I have also found that it's his favorite question to ask me during phone sex. LOL. "How wet are you???"
Happy Humping to all my fellow slip and slide gals!
