Satsuki, 28-year-old married woman. She deflowers a shy virgin boy whose cock is far larger than her husband's. During a close-contact mixed bath, her pussy throbs with arousal at the sight of his rock-hard, trembling erection. This experienced wife, vastly superior in sexual skill compared to the virgin boy, guides him through his first time, turning it into pure pleasure. She pleads, "Come inside me as many times as you want... just fill me up," craving creampie after creampie. An intensely satisfying, mutually pleasurable experience. How long can this bliss last?
