The series follows a young city boy who moves to the countryside for the summer to live with his aunt, Saki, and her two daughters, Rina and Kaede. Far from the innocent rural life he expected, he's immediately thrust into a world of unrestrained lust. His sexually frustrated aunt Saki is the first to seduce him, using her mature, experienced body to teach him the pleasures of raw, incestuous fucking. He soon discovers the two sisters are just as eager for his cock. The older sister, Rina, a busty beauty, enjoys rough, passionate encounters, letting him fill all her holes in secret trysts around the farm. The younger, more innocent-looking sister, Kaede, reveals a surprisingly kinky side, craving his seed and participating in wild threesomes. The story arc follows his complete sexual corruption as he becomes the personal stud for the entire family, engaging in a non-stop orgy of creampies, facials, and group sex, fully embracing his new role in this depraved country household.
