Pat401's hands tremble as he reaches for the pile of laundry, his step-sister's panties calling out to him. He's been caught before, but the risk only heightens his desire. He lifts them to his face, the scent intoxicating, the fabric soft from countless washes. He runs his tongue along the crotch, tasting her, his cock throbbing in his jeans. He unbuttons his fly, his erection springing free, and begins to stroke himself, his movements quickening as he pictures her in these panties, her pussy swollen and wet, her hips grinding against the fabric. He can't hold back, his cock pulsing, his cum staining the panties, a mix of his and her scent now, a secret only they share.
