The lewd, tight-fitting nursery nurse, Ayatsuki Nanao, JUFE-626, squeezes milk from the big, masochistic baby's penis.

"Gather yourselves, masochistic adults who want to become babies again~?" This is the only place where weary masochistic men can find healing and turn back into "babies"—Saiyue Nursery School. Like a saint, she gently surrounds you with her ample bosom—that's Teacher Nanao. But her true identity is actually a perverted nursery nurse in a bodysuit. On one hand, she heals you like a sweet and gentle mother; on the other hand, her discipline gradually escalates. For these "big babies," she engages in all-around perverted play in every place, culminating in a rape and ejaculation! Between constant climaxes and being brought to orgasm, the men are trapped in a dreamlike hell of healing and pleasure!
