Climax Game: My Big-Breasted Girlfriend Who Was Made to Orgasm by Hateful Men - Misono Kazuka, Yayoi Mizuki, Igarashi Mizuki, Ikuno Machi, DASS-534

Her lover confesses to Kazuka that he has an incurable disease. The cost of treatment is said to be prohibitive. Unable to accept reality, Kazuka sets off on her journey home, where a man approaches her. He tells her that participating in a special game and winning will earn her a huge prize, so she follows him to learn more. But when she wakes up again, she is dressed in a green tracksuit with a number and thrown into a shabby venue. She participates in this game, called "Ikase Game," along with one man and six women dressed similarly. It's a crazy game involving sexual intercourse, and the first person to reach orgasm is eliminated. The first match is "oral sex." Kazuka faces her former boss, who was reported and fired for sexual harassment and power harassment—although his unwashed odor makes Kazuka frown, she is determined to grit her teeth and suck his penis to save her lover.
