Due to numerous requests from viewers of her previous release, we were able to invite her back for another appearance, and Rina happily agreed to participate. Nearly half a year has passed since the last shoot, and Rina hasn't experienced any significant emotional changes—she still feels deeply embarrassed about filming her sex life and couldn't even bring herself to watch sample videos. Having never explored her sexuality or indulged in relationships with men, this shoot marks her first sexual experience in a long time. Her serious personality and position as a university lecturer may have made it difficult for her to express her sexual desires openly. However, desire exists in everyone. Triggered by the forbidden scenario of being asked to show her AV to her students, her masturbation intensifies rapidly. Her body trembles at even the slightest touch, and when the vibrator is applied to her pussy, she arches her back and reaches climax instantly—her sensitivity is extreme. In such a state, how could she possibly remain passive when a throbbing cock is thrust right before her eyes? We urge you to witness what happens next with your own eyes.
