At the entrance ceremony for the new school, Shinya falls in love at first sight with Sumire, a beautiful Sumire with big breasts who is in the same class as him. Sumire doesn't stand out, but she has a clear complexion and a very cute face. And above all, her large breasts are visible even through her uniform. However, Sumire's reaction is too weak, and even when he lightly touches her breasts, she doesn't resist at all... A new semester begins where he can do whatever he wants to Sumire!
