Satomi Kirihara, a beautiful and elegant woman, is troubled by her lack of a boyfriend and tries to investigate whether her body might be the reason, but she can't pinpoint the cause. When touched by a man for the first time in a while, her erotic switch flips instantly—her nipples become highly sensitive, and as fingers pinch them, she starts moaning cutely. And for good reason: her pussy is so sensitive from abstinence that penetration quickly makes her squirt. Though shy at first when faced with a cock, she dutifully performs oral, then eagerly asks for side-entry penetration. As her partner thrusts vigorously, the intense pleasure makes her head spin. Her exquisite reactions are so captivating they'll mesmerize anyone watching.
