Ayu Sakurai boasts an impressive track record of having slept with over 20,000 men, but just when she thought she'd experienced it all, a new door to pleasure swings open. Her heart is shaken by the raw allure of primal, instinct-driven sex—far removed from the scripted, proper performances she's known. Shedding her identity as an AV actress, she becomes nothing but a woman, surrendering to her instincts, wildly craving the cock before her. Unwilling to wipe away her sweat, abandoning all reason, she focuses entirely on luring the penis into her pussy. And in that moment, she discovers an entirely new ecstasy in sex.
