The cramped closet space serves as a makeshift confessional for the siblings. Michelle, haunted by religious guilt, pushes her baby brother David's massive cock inside her, his hard shaft rubbing against her tight, untouched vagina. David's fingers dig into her hips as he struggles to stay still, their father's commands echoing in their minds. But their bodies betray them, innate lubrication soaking David's cock as they slowly move, their taboo lust consuming them. They collapse in a tangle of limbs, Michelle's juices mingling with David's spent fluids, their post-coital remorse tinged with the lingering taste of forbidden fruit.
