Shy and reserved, Yuriko is always afraid to make eye contact, constantly looking down—an attitude that leaves a strong impression. Despite her mature demeanor for her age, her bashful expressions make her seem like a pure young girl. She speaks gently and kindly, yet her sexual preferences are surprisingly intense. She quickly voices her masochistic desires—loving rough play with toys, craving hard doggystyle thrusting. Unfortunately, I'm more of a soft-spoken type than dominant, but Yuriko is incredibly sensitive to even the slightest stimulation. A light touch on her neck, back, or sensitive spots draws out hot moans and soft cries of "Ahnn." Despite her shyness, she boldly presses the vibrator against herself, moaning passionately as if completely entranced—her nipples instantly hardening. At first, I simply enjoyed watching, but soon I couldn't hold back and just had to take her. Her voice starts hesitant, but gradually grows louder and more energetic. When I start pounding her from behind, a surprising transformation occurs—her earlier shyness vanishes like a lie, her ass thrusts back eagerly, moaning wildly. Completely different from moments before, she forgets all embarrassment, spreading her legs wide open. Who would have imagined such a quiet girl could turn so lustful? Was this the real Yuriko all along…?
