Its really hot if both are into it, or at least open to experiment. Its really amazing how a woman can really get into it. First time I took a strapon, it was her first time too. She came six times. Really amazing and hot.
Wife does me quite often. We have one called a feeldoe. shaped like a "J" and fits inside her too. She cums with me as hard as I do! Felling her quivering on the other end with it buried in my ass is incredable!
