[Milkdou Shoukai (Milk Koubou)] The Night My Sister Disappeared... I Made Love to My Mother... [Full Color]

A son's world tilts the night he catches his father and little sister China tangled beneath the bathroom spray, her breathless moans and giggled pleas to "Daddy" exposing a secret affair blooming right under his roof. When a disc documenting their forbidden lovemaking appears on the family table, mother and son are left to pick through the wreckage together—and Natsuki claims his mentally regressed mother Chigusa as his own lover, sealing their twisted new bond with tear-streaked kisses and vows never to leave her. Boasting enormous, heavy breasts at their shameless peak of maturity, Chigusa surrenders wholly to her son's devotion, with impregnation looming as the natural next step in this family's collapse into desire.
