Nishikawa Yui joins the simultaneous-orgasm series, built around a man and woman holding back to their limits before finally cumming together for an overwhelming rush. She enjoys watching a man struggle to hold out before sharing a devilish simultaneous climax, gets edged by an aggressive man until they cum together, and goes wild as both partners fight their urge to finish. Screams and shudders keep coming as ejaculation and vaginal contractions nearly make them lose consciousness again and again. Intense sex devoted to making every release feel even better!
