Noboru wanders into a village of voluptuous adult demon women where no men live, and the residents ask him to impregnate them all. In this third OVA adaptation of Momiyama's original Onichichi Harem, he heads to the village hot spring to recover from days of nonstop breeding, only to find it packed with demon women waiting for him. The bath is filled with their natural breast milk, whose effects make his whole body burn with desire and leave him obsessed with their breasts. He gives up thinking, resolves to suck every pair in the village, and the milk bath keeps his cock painfully hard with no sign of calming down.
