Euphoria

Is this cage hell or paradise?
They wake up in a white room remembering nothing
The protagonist Takato Keisuke and 6 others are locked up in these hidden white rooms. His childhood friend Hokari Kanae, classmate Andou Miyako, underclassmate Makiba Rika, English teacher Aoi Natsuki, same year Byakuya Rinne, and classmate Manaka Nemu. While still confused about their unusual situation, a "mystery voice" suddenly speaks to them: "A game has now started."
In order to escape the room, Keisuke is the "unlocker" and one heroin the "keyhole". With an assigned act, he must "use the key".
After hearing the unreasonable and immoral requirements to win, Miyako gets pissed and snaps on the "mystery voice". Suddenly the lights go out. The girls are screaming. The lights come back on, reilluminating the white room. They can see Miyako bound to a grotesque torture device.
"Anyone who quits the game will die"
Her screaming starts in tandem with the electric current. With eyes wide open in fear, she pisses and shits herself. Everyone else starts freaking out. However, Keisuke seemed to be getting aroused by Miyako's appearance. That was his secret, his urge to assault and humiliate the girls.
However, Nemu could see right through him and knew. Nemu takes advantage of forcing the protagonist to submit to him as she brings her lips up to his: "This is a contract kiss."
Kezuke was surprised by Nemu's behavior but he wants to protect Kanae and decides for the sake of escaping, he will violate the others. Could you escape the white rooms and return to his normal life? Or will he hold back his own dark urges ...? It is you who decides in the end. Check out a game with a similar genre shihai no kyoudan.
