Tomoya, a son who respects his modest and quiet mother Yuri (Kitahara). Yuri, who always smiles and behaves cheerfully, was the best mother for Tomoya, but... One day, Tomoya casually enters his mother's bedroom and discovers a large amount of sexy lingerie and perverted toys. That night, Tomoya makes up his mind to look into his mother's bedroom. What I saw there was a mother who wore lingerie and went crazy with toys. Tomoya feels sexually aroused by the sight of such a mother.
