[Dokutoku no M (Denchi)] Stepmother's ATM

A towering, big-breasted stepmother has built a chip-linked system to drain money from her adult stepson Haru, then subjects him to a circle of equally voluptuous women for far more intimate trials. Strapped to a chair and blindfolded, Haru endures bondage, tickling, genital teasing, and orgasm denial, his confusion and pleas slowly fracturing under their synchronized control. His desperate cry for release meets the stepmother’s unnerving tenderness—embracing him after declaring her love—promising that humiliation and possessiveness will remain tightly intertwined.
