I want to be my mother!

Tomoya, the son, never stops respecting his mother, Yuri (Kitahara), who is modest and quiet. Yuri, who always smiles and behaves cheerfully, was the best mother to 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 decides to look into his mother's bedroom. What he saw there was his mother wearing lingerie and writhing in agony over a toy. Tomoya feels sexually aroused by the sight of his mother, something he doesn't usually get to see.
