Reunited After Years: Cousin’s Explosive Growth

Synopsis

Riho, a high school student, comes to Tokyo to prepare for entrance exams. She stays with the Kimura family, relatives of her parents. The Kimura household has a son named Ichiro, an unmotivated ronin student who spends his days masturbating instead of studying, showing no signs of academic improvement.

When Riho and Ichiro reunite after about 10 years, Ichiro is shocked to see how much his cousin has developed—her body has transformed dramatically with her voluptuous figure. Remembering their childhood when they frequently bathed together and slept in the same room, Ichiro finds himself captivated by Riho’s physical transformation.
