A chick who likes muff diving.
My sister and I had a mutual female friend who was over to the house one day, while our parents were gone, and I was really hoping to score. I got her into the guestroom, and went to the bathroom to freshen up.
While in the bathroom, I heard my sister come home. I heard some talking, and then some muffled groans. When I walked into the guestroom, my little sister was playing Little Miss Muffet on our friends muff. Then our friend asked me to come over there stuff my cock into her mouth.
It's really much more fun to just stop here and leave you hanging!
