Fart Punishment

I have always loved sneaking into my big step-sister’s room and smelling her worn panties….but unfortunately today i dropped the ball and forgot she was home. my big step-sis catches me in her room going through her used laundry….she catches me sniffing her used panties and even putting a pair of them into my pocket to sniff for later. my step-sister calls me a pervert and them all of a sudden i am strapped down to her bed with a pair of hair restraints. step-sis climbs up on top of me and tell me i am about to be punished….she says since i like smelling dirty panties so much she has something even stinkier for me to sniff. she pulls down her pants and begins farting and making me sniff her dirty asshole and inhale her period farts that smell absolutely disgusting.
