You pass my room and see a crack in my door. You spy in and see me masturbating. You cant help but get turned on by the thought of smelling your sisters dirty panties. After I leave for the day you go in there and steal them. You forgot to bring them back to my room and a couple days later I find them in your room. Afraid I might tell mom and dad, but that's not the case ;) I think its kind of hot...
