Rioka is a student at a certain famous national university. She made a big break with her healthy body, trained through swimming, and now she's back for summer vacation. Her tanned body with clear traces of her competitive swimsuit is very sensitive and erotic. Rioka says that abstinence was tough, and she let out all the erotic desires that had been building up during summer camp. "Sports girls are very erotic" The rumor seems to be true.
