[Mitari Gakuen (Nush)] Mitari no Sono (Ep. 174-177) [Full Color]

Kei shuffles back into the Slave Training Room with no means to resist, and his mistress's mother is waiting, stilettos clicking, to remind him who truly owns his body. She kicks and grinds his bare cock and balls underfoot, then slips off her heels and makes him service her soles before milking him with her feet again and again until he's sobbing that he has nothing left, scolding him the whole time for finishing without her permission. With the girl who owns him smugly admitting how easy it is to break him when mom handles the discipline, this is foot-focused femdom torment from first heel strike to final drained confession.
