The sisters, their inhibitions lowered by the dim lighting and the quiet hum of the old fan, begin to undress each other, their movements slow and deliberate, like a dance they've been practicing for years. The elder sister's hands tremble as she unhooks her sister's bra, revealing her small, pert breasts. The younger sister, her eyes locked onto her sister's, bites her lip as she slides her sister's panties down her legs, her fingers brushing against the elder sister's wetness. They fall onto the bed, their bodies entwined, their hearts beating in sync, as they lose themselves in each other, their moans filling the room, their bodies slick with sweat and desire.
