Rei Aino is a stunning nail technician with an unexpected secret: despite her beautiful appearance, she indulges in daily masturbation. When molested, she becomes aroused by the situation and says "That was good" with apparent satisfaction—revealing a masochistic, perverted personality beneath her composed exterior. As her prized waistline and body are caressed, her affectionate, needy side emerges, creating an irresistible sense of gap appeal. Though anoreceptive sex is new to her, her highly sensitive, responsive anus quickly grows lustful and depraved. Desperately chasing pleasure, she cums repeatedly, and even after receiving massive facials, she asks for more—truly embodying the insatiable "come again girl" type.
