[Ikinariya (Ikinari)] Futanari Ojou-sama no M Dorei Shasei Kanri [Full Color]

A haughty futanari ojou-sama keeps her masked male slave under strict ejaculation management, his cock cinched tight in straps while she teases him breathless with gloved hands and a slick toy. She smothers him beneath her plump ass, milks every drop of his stored load, then sinks her own thick shaft deep into his hungry hole and rides him until he's begging to cum all over again. Even after he erupts, her sweet smile promises three more rounds—his release schedule belongs entirely to her.
