In the throes of religious guilt, cousins Desiree and her brother sneak into a cramped closet, their hearts pounding with anticipation. Desiree, her eyes wide with forbidden lust, takes in her brother's massive cock straining against his pants. "We mustn't," she whispers, but her hand betrays her, reaching out to stroke the bulge. Her brother, equally entranced, pushes his hips forward, a bead of pre-cum forming at the tip. They stumble through a dance of lust, their bodies pressing together, hands exploring, until they're a tangle of limbs and gasping breaths, their taboo passion consuming them.
