Tenkawa Noboru, exhausted from his tireless efforts at fatherhood, heads to the village hot springs to relax. However, upon opening the door, he finds himself confronted by a packed crowd of oni maidens.

The hot spring water is entirely the oni maidens natural breast milk. The effects of the breast milk heat his entire body, leaving him dominated by breasts. Noboru decides to stop thinking and dedicate himself to sucking on every breast in the village.

His groin, now fiercely erect thanks to the milk bath, shows no signs of calming down.
