[A lovey-dovey anal play work for women] Waka and Riku are a lovey-dovey couple. One day, Waka hears from a friend that "men who get off on anal are cute," and becomes interested in men's anal. Since she has no interest in other men, she asks Riku to develop her anal... Riku originally said that he was normal and that he didn't want anal... but he gradually succeeds in developing it, and in the end, Waka's own ass pussy is completed, where she can only get off on her ass!
