Nao Kasukabe is a famous troublemaker in school. Right now her “boom” is whopping masturbation! She’ll start a new club involving her childhood friend Hibiki, her classmate Norika, even Mako the upperclassman. Its name is “Ona-Ken!”
The club activities will be forced conversation while masturbating with pink-cheeked shame. Norika and Mako talk explicitly about how they’re touching themselves, and Nao demonstrates the variety of masturbation methods of women using her own body.
Ona-Ken! is the pursuit of great masturbation. What heights will eager loins reach when they belong to girls who never get tired of jilling off?​
