Nana, a high school girl, is always alone at home because both her parents work. Tomoka, a housewife who lives nearby, is captivated by Nana's translucent, white, soft skin and youthful scent, and approaches Nana under the pretext of helping her with her studies. Not realizing that the drink has been laced with an aphrodisiac, Nana takes a sip of the drink Tomoka gives her and falls into a deep sleep. Tomoka enjoys her silky hair and sweaty crotch, but the effect is weak, and Nana wakes up. Suspicious, she goes home, but Nana's body, having experienced the pleasure, heads back to Tomoka's house once again. After being drugged with the aphrodisiac, Nana's whole body becomes sensitive, and she is unable to resist Tomoka's actions, reaching her first orgasm as her shaved pussy becomes soaked.
