Yuuri, the stepchild of his second marriage, is too spoiled. She says, “Take a bath!” For some reason, she doesn’t like taking baths. The story begins when she usually comes with her mother, but her mother is away for a period of time… “I’m scared of baths, so I’m going to take a bath with my dad!” Yuuri, who is old enough to never take a bath by herself, reluctantly takes a bath and gets pranked! When I looked at Yuuri to shake it off, I saw that her breasts had grown nicely and were jiggling! Although she manages to maintain her rationality, her body obediently becomes erect, and Yuuri also becomes interested in the penis… An ambitious work that also includes a super rare shampoo scene!
