A father's strict orders lead his daughters to an unholy act. In the dim light of their shared room, the sisters, clad in modest nightgowns, approach their brother with trepidation. His cock, already tenting his pajamas, twitches as they near. The eldest, her voice barely above a whisper, says, "Father commands us to verify your purity." She gently pushes his boxers down, revealing his thick, uncircumcised cock. Her sister, younger but no less devout, watches, her breath hitching as she sees her brother's manhood for the first time. They touch him tentatively, their soft hands exploring his length, feeling the heat and hardness. The oldest, her face flushed, leans down and takes him into her mouth, swirling her tongue around the head. The younger sister watches, her own body responding to the taboo scene, her nipples hardening, her pussy dampening.
