Umi Yatsugake from PRESTIGE is lured into pleasure by cocks other than her boyfriend's. Umi and Yuta were the couple everyone at school recognized. Their relationship began when Umi, a modeling subject, met Yuta, a member of the photography club. However, things take a dark turn when the club's advisor, Oki, drags them into increasingly extreme photo shoots. Umi is forcibly fucked, then repeatedly blackmailed and coerced with the gonzo footage. This includes being toyed with at Oki's house using sex toys, and even being made to play with clients at a brothel. Continuously drawn into perverted acts, Umi discovers true pleasure and eventually starts craving sex with Oki instead of Yuta. Witness the ultimate depressing, boner-inducing NTR footage as the girl he loves falls deep into a spiral of ecstasy.
