No matter where you are in the house, you can't help but notice the bouncing breasts. The massive chest of Yuika (Rinne Tuka), the mother-in-law, is all that Yoshio can think about. In front of a teenage boy, her unrestrained bouncing breasts capture his gaze. Yoshio's mind is completely filled with thoughts of breasts. (Maybe if I just touch them once, I'll calm down...) Unable to resist the urge to grope them, Yoshio decides to trap Yuika just this once... but the first time he touches her breasts, he becomes unexpectedly engrossed in them...
