In the confines of her bedroom, the sister takes charge, her small, firm tits pushing against her top as she demands her brother's attention. She pushes him onto the bed, ordering him to undress while she teases him with her body. Once naked, she straddles him, rubbing her pussy against his hard cock. She commands him to cum, to spill his load onto her stomach, marking her as his dominant. She licks his cock clean, her eyes gleaming with power and satisfaction.
