The series follows a young man who moves in with his childhood friend, Nanako, and her stunningly voluptuous mother, Sayaka. Overwhelmed by loneliness and pent-up lust, Sayaka wastes no time in seducing him. Their nights escalate into raw, passionate fucking sessions where he relentlessly pounds her dripping wet pussy until she's screaming his name, filling her mature womb with his hot cum. The story intensifies when Nanako discovers their affair. Far from being horrified, she's consumed by a jealous lust of her own, demanding that he fuck her just as hard. The series arc culminates in a depraved but blissful household threesome, where the protagonist alternates between fucking the mother's tight, experienced cunt and the daughter's fresh, virginal snatch, breeding them both and covering their faces in his seed.
