Beautiful double eyelids that convey a strong will, and large eyes that seem to suck you in. Seira (24), an apparel salesperson who wears casual clothes on her slender body with a stylish atmosphere. Her well-defined features make her seem somewhat unapproachable and slightly haughty. However, once you talk to her, she is a curious girl who loves alcohol and music. Her slim body consumes energy every day from standing work, and she doesn't gain weight even when she eats. She is so slender that she seems almost fragile, as if she might break. With such a physique and personality, she applied for this shoot. "When I'm drinking, I tend to get in the mood," she says calmly with a cool face. Her interest in erotic things is quite strong. She has no resistance to sleeping with men she has just met, and she masturbates every day while indulging in lewd fantasies. Rather than being treated gently, she prefers rough play, such as having her neck held firmly or her ass spanked. She takes off her black lingerie, gets on all fours with her slender body, and gets spanked, becoming disheveled. Although she didn't break her cool expression at first, she lets out loud moans every time her ass is spanked hard, gradually transforming into a submissive figure. Please don't miss this vivid change until the very end.
