JUL744 — My Wife's Adult Sister Secretly Tempts Me Around the Clock, Hungry for My Huge Cock

Nono has only just married when her husband leaves for a three-month solo work assignment. Worried about her living alone, her adult sister and brother-in-law invite her to stay with them. Life is peaceful at first, but her mounting sexual frustration leaves her masturbating almost every day. Then she discovers that her brother-in-law Tetsuya is also tormented by a sexless marriage—and is hiding an exceptionally huge cock. Unable to contain her aching desire, Nono begins secretly seducing him. Tetsuya gives in to her devilish advances, and their forbidden relationship soon starts drawing him in deeper.
