[Oshima Aki] When Dad and Mom Aren't Home [Full Color] {FuDeORS} [Decensored]

Young Masaki's new stepsister wastes no time proving he's 'no longer alone' once their parents step out, smothering him in her huge, soft breasts before taking every inch of him deep inside her. She rides him with shameless x-ray clarity, demanding he watch as her slick, wriggling insides grip him tight, and even a close-call phone call from Mom can't cool the heat between them. Sweaty, teasing, and utterly devoted, she promises to stay with him until he's completely satisfied — and this insatiable big sister always keeps her promises.
