30-year-old Keiko stands 165cm tall, weighs 56kg, has blood type O, and a slender, alluring figure measuring B91 (D), W62, H90. The moment a large cock enters her body, her previously calm demeanor completely transforms—she becomes as if dominated, screaming out loud, "No, no, nooo!" and "Yes, yes, yes, it's good!" Her high-pitched, powerful voice surprises even her partner. With her tall, slender frame, fair skin, narrow eyes, slightly messy curled hair, and excellent fashion sense, she looks like a stunning woman. However, she is also a divorced mother of two, having married at 21 and separated five years later. Since then, she's been striving as a single mother, yet her female desires remain uncontrollable. When a man touches her body during a shared bath, she trembles and furrows her brow. With the typical submissive woman's upward glance and insecure eyes, she watches her partner's reactions. When her pussy is licked, her abdomen twitches repeatedly as she moans in embarrassed arousal. Once moving to bed, she begins moaning louder than usual—"Aaahn, Haah-aan"—sucking the cock, straddling his thickened shaft, and awkwardly grinding her hips. When penetrated deeply in missionary position, her voice shifts tone—her face contorts as if in pain, turning into screams of "No~oo, ahh! Aaah!" Then, in the next instant, the same tone becomes "Yeeess! Yeess!" followed again by "No, haaahn, nooo, nooo, no, no, no!" shrieked at full volume. When taken from behind, she grips the sheets in front of her tightly, stiffening her body as if enduring something, moaning in shrill cries. Returning to missionary for the final thrusts, her moans transform into an ear-piercing, frantic shriek unlike any ordinary sex cry—like a woman being attacked—as she rockets to climax. When first met, she appeared as a composed, elegant woman who quietly admitted, "I'm an M woman." But once undressed, she revealed a body far beyond imagination, and during sex, her extreme sensitivity emerges with sobbing moans, unveiling the long-suppressed, smoldering desire of a woman in her thirties.
