During a routine shoot, PR department veteran Natsumi Aiba gets ambushed with a sensitivity test. She’s a sharp-tongued girl in glasses, but her body is surprisingly innocent! She tries to bite her lip and hold back against her first vibrator, but once she’s penetrated, she loses all control, screaming 'That feels too good! Don't stop!' as her ultra-sensitive nature is laid bare.












The actress is Saryu Umizu. Her initial refusal to masturbate shows a prickly personality that really built up my expectations. She starts doing it with a half-hearted attitude, but then suddenly transforms into a cute girl. She seems much slimmer than before, but she's still beautiful (if I'm being biased). However, the actual scenes were very standard, and there weren't many exciting moments. I wanted to see her act more reluctant or embarrassed, so it was a shame she was so confident. The actress is top-tier, but they needed to put more effort into making it look erotic.
