A charming older woman with exceptionally detailed nail art makes her appearance. She reportedly paid 10,000 yen for a 2.5-hour nail care session. A professional nailist by trade, she's known as "Natsuki, the girl with such beautiful nails," and her intricate designs are truly astonishing. She's also deeply passionate about sex, having had her first experience in a school infirmary during middle school. Since then, she's been obsessed with sex and once maintained a rotating relationship with three casual partners. Now, she strongly desires to have sex every day with her boyfriend. Influenced by these intense experiences, she's highly sensitive not only at her nipples, clitoris, ears, and neck, but also on her buttocks and inner thighs. Natsuki, the girl with such beautifully manicured nails, boasts a wide range of erogenous zones, revealing a promiscuous charm through her diverse sexual experiences.
