Her name is Mina, nicknamed "Limit Breaker Mina." Her sole purpose in life is one thing: surpassing limits. It all started in childhood. Once, while holding in her pee during an outing, she managed to endure for hours until finally returning home. The intense sense of accomplishment and overwhelming release she felt when she finally let go completely captivated her mind. Ever since, she's never stopped challenging her limits—how many days she can go without sleep, or how long she can resist orgasm. One of her most memorable challenges was during high school, when she pursued extreme weight loss. Through relentless exercise and fasting, she dropped down to 36kg, but suddenly experienced blurred consciousness and strange physical symptoms so intense she described seeing "fields of flowers." That's when she finally stopped. Now, her current challenge is to see how long she can last during sex without cumming. This stems from her realization during the weight loss attempt: there are two reasons she pushes her limits—the thrill of achievement, and the euphoric release that comes from enduring unbearable tension and finally letting go. But recently, she's become too obsessed with achievement and nearly forgotten the pleasure of release. To regain balance, she began masturbating every night and started sleeping with a fuck buddy, having sex 5 to 10 times a month. Her application for this AV shoot is part of that "training." But a pro's touch is merciless. Skillful fingers expertly tease her pussy, precisely targeting her most sensitive spots. Then, the powerful vibrator drives deep, followed by a rock-hard cock ruthlessly pounding into her without mercy. Even Mina, known as the "Limit Breaker" who's overcome countless boundaries, finds herself wavering, thinking, "I... might not make it." Yet she keeps pushing forward—determined to surpass every limit. Incidentally, without even realizing it, she continues to extend her "longest time without a boyfriend" record. Though she's had plenty of sex, she pays no attention to her partners' looks or the quality of their sex. Right now, she's so fixated on resisting orgasm that she's blind to everything else. It's a shame—such a cute girl with a beautiful face and slim figure. Someone reading this, please—teach her that happiness exists beyond mere endurance.
