Your sister barges into your room one day pissed as hell, clutching a pair of her panties. You immediately know what's wrong. You've tried for months now to resist your urges, but you just can't control the insatiable lust for your sister's panties and you are still constantly stealing, sniffing, and jerking off to them. "This has gone way to far. You need to be taught a lesson" she says scowling, "you love my panties so much? Here. Let me see you sniff on these." She opens up the pair in her hand to reveal that its covered in skid marks. She laughs, pushing them in your face. You gag and attempt to pull away; you love her panties, but not like this. "Don't you try to run away you little prick. You're lucky this is your punishment, you don't want me telling MOM again, do you?" You don't. Last time this came out she beat you raw and grounded you for months. The women in your family have always been superior and have always turned against you. You reluctantly begin smelling her panties, taking in the powerful stench, trying not to throw up. "Now lick them!" she orders sadistically. You beg her not to and she smacks you hard across the face, "DO IT," she screams. You feel helpless and begin to cry as you slowly run your tongue across the soiled crotch. Sister laughs as she barks orders and then both of your surprise you dick begins to stand on end. "Oh… my…. GOD… You're enjoying this aren't you?" she says shocked and disgusted, "I guess you have a new fetish now, you sick fuck. You're going to grow up to be one of those perverted creeps that no woman will ever fuck." She laughs and then orders you to pull out your cock and give it the only kind of pleasure it will ever experienced. You feel humiliated, ashamed, yet uncontrollably aroused. You can't help but obey her every word.
