Thank you for supporting me for a long time.
This game has been on sale for a long time but we decided to lower the lowest price so that more people will be pleased.
I am sorry for those who purchased at regular price.
However, we are considering registering other works on this site and it is also the purpose of raising development funds even a little.
I am happy that we will continue to pay attention to our activities.

1: Introduction

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?

2: Sales point
The theme of this title is Masturbation.
See the sometimes cheerfully liberal, sometimes obscenely ribald "secret doings" of girls who love masturbation. Each has a maniac obsession with making herself feel good that's beyond imagination!
And when the members of Ona-Ken! can no longer be satisfied with just onanism... (multi-endings) ... the result is a must-see.

Please enjoy the "HENTAI" of girls that's more than we men can fantasize.

Locale Emulator worked pretty well to run this game.

So I bort this game the other day and when ever I try to extract the setup file I keep getting a Error 0x80004005. I have tried using a repair toul but I still wont extract. Is there anything else it could be?

It is for Win10.
