Yui works as a secretary surrounded by powerful men. Though she appears reserved and proper at first glance, she's actually had experiences with over 20 men and has even had sex in her company's emergency stairwell—a truly bold woman. When asked to masturbate, she pretends to be shy, but as soon as the vibrator touches her pussy over her panties, her legs twitch in response. When I snatch the vibrator and relentlessly tease her, her legs shake violently as she cums—so hot! After licking her sensitive pussy, her initially cold demeanor gradually softens. Her speech becomes more relaxed, and she slowly opens both her heart and body—watching Yui's transformation is incredibly captivating. She says she likes cocks that aren't too big or too small—so how about mine? Let's get her judgment! She happily takes it into her small mouth with a cute "pop," giving an amazing blowjob. Her skillful tongue work inside her mouth makes you wonder where she learned such erotic techniques... A cool beauty with deep eroticism—absolutely perfect. When I enter her in missionary position and start thrusting, she clings tightly to my body, moaning sweetly and erotically. She claimed she's not good at cowgirl position, but once we switch to it, she actively grinds her hips with clear pleasure. Her eyes glazed over, proudly displaying her pussy while energetically riding me—so damn sexy. As I pound her thoroughly soaked pussy, lewd squishing sounds echo throughout the room. After intense, repeated thrusts, I finish by cumming on her stomach. Gradually melting into affection, Yui ends the session with a lovely, happy smile.
