While hanging out at his friend's house, Takahashi, a high school boy, met his friend's mother, Miho. Takahashi was interested in women around his mother's age, so he pretended to be a college student and started using a dating app, only to match with a frustrated married woman. When they met and removed their masks, it turned out to be Miho, Takahashi's friend's mother. Takahashi was conflicted about having sex with his friend's mother, but Miho pushed him and the two ended up having sex.
