爆乳好きの彼氏の「意外と小さいよね」という一言で傷ついたみゆちゃん。ママの勧めで自宅育乳エステをお試しすると、担当は怪しい男性施術師。不安を抱きつつ受けると、徐々に卑猥なマッサージに…。胸の成長を実感し、恥じらいながらも通ってしまう。やがて乳首を執拗に開発され、敏感になりすぎてエビ反りで乳首イキしてしまうほどに。理性が崩壊し、最後には施術師との禁断のセックスまで許してしまう――。純粋な美少女が快楽に堕ちる、背徳の育乳エステ物語。
Miyu is hurt when her boyfriend, who likes big tits, says, “They are surprisingly small. On her mother’s recommendation, she tries a home breast-building esthetic treatment, and finds a suspicious male therapist in charge. She is anxious to try it out, but as she receives the treatment, she is gradually subjected to an obscene massage…. She feels her breasts grow, and she is ashamed to admit it, but she keeps going. Eventually, her nipples are developed so relentlessly that they become so sensitive that they come in a shrimping motion. Her rationality collapses, and in the end she even allows herself to have forbidden sex with the therapist. This is an immoral tale of a beautiful young girl’s fall into pleasure at a nipple-enriching beauty salon.
