26-year-old married woman Emi decided to appear in an adult video because, after two years of marriage, her sex life with her husband had decreased, and her desires for pleasure and money had grown stronger. Worried about being discovered—"My husband absolutely must not find out"—she soon forgets about him once filming begins, becoming absorbed and lustful with a naughty expression. As her clothes are gradually removed and her skin exposed, she blushes and looks embarrassed, an adorable sight. Her shyness is further drawn out by performing public masturbation in the bath. This is followed by thick vibrator blowjobs, full-body lotion massage, and intense scenes, during which she pleads, "I want a cock inside me now." Before that happens, she gives a blowjob to relieve me, finishing with a mouth orgasm. Prior to penetration, she's dressed in a school swimsuit and attacked with a vibrator. The stimulation proves too strong—she ends up leaking a large amount of urine uncontrollably. Reaching her limit, she mounts me herself, riding hard and grinding her hips, clearly aroused by my stiff cock.
