A Japanese animation featuring a family's intergenerational service in a hot spring

In the heart of Japan, a family-owned hot spring resort has been the center of a unique tradition. The eldest daughter of the family, with her voluptuous curves, is entrusted with the responsibility of providing erotic services to the guests. The youngest son, a deviant with a fetish for his sister, is the gatekeeper, ensuring no one interrupts their intimate encounters. The father, a cunning master of seduction, joins in the fun, while the mother remains oblivious to the steamy goings-on. Every night, after the guests retire, the eldest daughter sneaks out of her room, her lips eager to please. The youngest son, hidden in the shadows, watches as she engages in passionate acts with the guests. This is a tantalizing tale of forbidden desires and family secrets, set against the backdrop of a serene hot spring resort. This is an unforgettable journey into the world of Japanese adult cartoons, where the line between fantasy and reality blurs.
