Wanting to increase her small A-cup breasts—once a source of insecurity—she began visiting a breast enhancement salon, driven solely by the desire to be praised by her boyfriend. However, she soon realizes the salon is actually run by a perverted masseur who uses aphrodisiac oils to perform lewd massages. As the sensitive girl is coated with the aphrodisiac oil, her body rapidly awakens. Overwhelmed by intense pleasure she's never experienced before, her tanned, slender body trembles and she climaxes, her face flushed with arousal. Her hypersensitive nipples are teased until they orgasm repeatedly, causing her to lose control and urinate profusely. "Sensei... I'm going crazy... Please, do something to me...!"
