[Reducing Mosaic]JUQ-285 Invited by a mom friend to a matching app, we'll raise the 'underage idol' together and make him sweet and tame.

Ryo and Kaho are good mom friends. One day, when she is having a tea party as usual, the topic turns to her sex life. Kaho seems to have a fulfilling sex with a young man she met on the app, and Ryo, who thinks it's suspicious, starts the app as she is swept away. Yuzuru, a student who got acquainted with the app, wakes up to the pleasure of being obedient and dominating. And Yuzuru is also drowning in the bewitching and sexual appeal of a married woman, both in mind and body.
