Fair-skinned, beautiful-breasted Rena Mitsuhana has been trained by her master until her body constantly craves sex. The rope around her wrists has become so comforting that she cannot relax without it, and merely having her tits fondled from behind makes her heart race. Kept without panties, she is desperate for stimulation, even if she must masturbate. Her master’s big cock is her favorite thing: she wants to suck it, take it inside, and have sex again and again every day.
