After a life of regret, 30-year-old Souta is miraculously sent back in time to his childhood body with his adult mind intact. Seizing this second chance, he embarks on a relentless quest of sexual conquest, determined to fuck every woman he ever desired. His first target is his stunning, busty aunt, Kaori, whose ripe body he'd always lusted after. He seduces her with his adult cunning, burying his face in her massive tits and ramming his tiny cock deep inside her dripping wet cunt until she screams with forbidden pleasure. Next, he turns his attention to his delinquent gyaru classmate, Remi. He overpowers her bratty attitude, bending her over a desk and hate-fucking her tight pussy raw, filling her up with his seed. Not even his teachers are safe; he blackmails the prim and proper Ms. Arisugawa, forcing her to submit to his every depraved whim, fucking her mouth and ass until she's a broken, cum-covered mess. Souta's journey is a non-stop barrage of hardcore, taboo-breaking debauchery as he uses his new life to satisfy his deepest, darkest lusts, turning his past into his personal fucking playground.
