Husband Cheats on Vacation: Affair with Wife's Younger Sister

With a marriage that has grown distant and passionless over time, this husband finds his secret obsession blossoming for his wife’s younger sister. After a year of missed opportunities due to demanding work schedules keeping them apart from Karen Yuzuriha, he finally arranges a clandestine hotel rendezvous just as his wife embarks on a solo trip. The reunion ignites an unstoppable primal urge; they devour each other passionately like wild beasts. The encounter quickly escalates far beyond casual intimacy. Driven by months of pent-up desire and longing for Karen, the husband demands—and she enthusiastically grants—the chance to ejaculate every drop of accumulated seed inside her. From dawn till dusk and continuing through the entire night until morning, they refuse to waste a single glorious moment together.
