You need a Windows PC to play this game.

This game combines four adult free games previously created by our circle into a single game. There are four mini-games to play. Achieving high scores unlocks reward illustrations.
Most of the content is the same as the free game versions, but this time, you can see "nipples" that weren't visible in the free versions!
Feel free to stream or record gameplay.

You can control the game using a keyboard or gamepad. While all games have very simple controls, some may be easier to play with a gamepad.
Where you are instructed to press the SPACE key, you can also proceed by pressing the B button on your gamepad.
Pressing the Esc key (or the Start/Option button on your gamepad) during a mini-game will open the pause menu.

• Supports Japanese and English.
• Only the nipples have been unlocked. The lower body is the same as the free game version. There are no depictions of genitalia or sexual intercourse.
• As mentioned above, the games playable in this collection are originally "free games." Please note that you can play them for free anytime if you do not need to see the nipples.
