A married woman's heart and body on a hot spring trip. Though pure and gentle, she struggles with her relationship with her husband, who has become more like a roommate, spending weekends apart. She decides to have an affair. When praised, she freezes up—but once she accepts a kiss, her eyes grow sensual. When her underwear is removed and her genitals stimulated, her entire body trembles and her hips twist involuntarily. She compares the erect cock to the man's face, then takes it into her mouth, pleasuring him orally. Riding him in cowgirl position, she rhythmically grinds her hips, climaxing loudly in simultaneous orgasm. At night, practicing how to seduce her husband, she initiates kissing and takes him in cowgirl, thrusting wildly as she screams without pause. "Fuck me harder!" "Give me more!" she shrieks repeatedly. In the morning, before breakfast, she teases, "Wanna suck it?" with light penetration, then after the meal enjoys doggystyle against the window.
