Description:
Kou Saotome is smack in between Arisa and Ruka, the middle brother of two sadist sisters.

Between them he's constantly getting * into things. They're not even the only ones.

At some point a guy's just gotta surrender: "Okay, I'm a slave to all women, I'm a masochist!"

3. Translator's Notes:
- Menus: "I have edited the interactive parts of the image menu to be in English. Not well, but it should be bug free and allow you to enjoy the main game. If you encounter any issues with the edited graphics, please contact me (see below)."
- Content: "Just so you know what you're getting into. This game is focused around non-consensual sexual situations, including (in this patch) footjobs, handjobs, anal insertion, public use of a remote-controlled vibrating dildo, eating food on the floor and on human feet, golden showers, pegging and oral sex, public crossdressing, public humiliation, public nudity, petplay, whipping, candle wax, and being * to consume semen. It also contains elements of transphobia, public sex, bestiality, and a reference to suicide."
