[Hashida Mamoru] Yutori (Shiritsu Inwai Gakuen) [Decensored] [YxTL]

A warm-hearted mother welcomes her son Nao-kun home, only to discover he's brought along the very classmates who bully him. When they offer a deal—her body in exchange for her son's safety—she endures being held down and shared between them right before his eyes, her experienced curves pushed past every limit as she begs for help that never comes. The gut-punch finale belongs to Nao-kun himself, who tearfully apologizes again and again while claiming his mother for his own.
