28-year-old female teacher Tsugumi Niiyama, three months postpartum, celebrates the return of her milk supply with scenes of abundant lactation. After returning to her teaching job, she is sexually tormented by failing students and delinquents who play with her Holstein-like breasts, forcing her to release milk amid pleasure and humiliation. Her self-milking, pleasure-filled expressions embody ultimate taboo and perversion. In after-school scenes, titty-fucking soaked in breast milk leads to ultimate ecstasy. The teacher's large nipples are intensely stimulating, haunting viewers' dreams, as they witness the dark, thick nipples gushing copious milk that is eagerly drunk down—truly a shocking, erotic masterpiece.
