I sniff my girlfriend's younger sister's panties. She always wears thongs for some reason. She is incredibly cute and sexy and I could'nt help it. After 6 years of knowing her and seeing her one time accidently in her bra and panties ( she was vacuuming her room and did'nt know I was home) I decided to take a sniff. I felt bad at first, but became aroused. I just love the scent and I get off on it. I suppose it's because I do it when no one is home, that it is exciting and very addicting.

Has anyone else fantasized about getting it on with their gf's younger sister (she's 21) or taken a whiff of their undies? Or am I the only sick freak??!!
