44-year-old Yuka (154cm, 49kg, B94 (D), W65, H91) divorced nine years ago and although she's had a few boyfriends since, she hasn't been touched by a man in the past four years. She secretly relieves the intense sexual desire that arises after each period through masturbation, careful not to be seen by her daughter. Her method of masturbation has always been irregular—limited solely to stimulating her nipples with a small brush and ice, never touching her lower body. As a result, her clitoris has never been touched, and nothing has ever penetrated her vagina. Her sexual awakening began with menarche, and her earliest masturbation experiences involved fondling her breasts, with her most vivid memories dating back to middle school. She has no prior experience with bondage, blindfolds, or urination play, and remains largely ignorant about sex, asking, "I don't know what orgasm feels like—what does it mean to 'come'?" When placed face down and her back is traced with fingers, she reacts instantly: "Ahh, that feels so good," "I never knew my back could feel this good." Tracing the outer edges of her hips, she moans repeatedly, twisting her hips, saying, "My ass feels so good—ahh, so good." She responds intensely to touch at the tops of her thighs and behind her knees, confessing, "I need slow, thorough foreplay to feel pleasure." When her clit is touched, she murmurs, "I think I want it," and as stimulation continues, she begins to pant. "It feels good—I had no idea my clit could feel this amazing." Starting with finger play, she begins rocking her hips as a vibrator is introduced. As moans build, she's asked, "Don't you want fingers inside too?" to which she gasps, "Please put them in," guiding one finger, then two into her vagina, crying, "It feels so good." As the pace quickens, she reacts, "I'm gonna come?"—"I don't understand, my mind's gone blank"—then shouts, "I came!"—"It's so deep, the pleasure is completely different." With her first experience using a vibrator, she reaches climax within 6 to 7 seconds, orgasming fully at 15 seconds. Afterward, lying sideways on the bed, she begins by groping her left nipple, kneading and pinching it. Then, using a fine brush, she carefully strokes around the areola. Dipping the brush into ice water, she slowly traces it around her breasts, letting out soft sighs. When the cold sensation fades, she wets the brush with an ice cube and presses it directly onto her nipples, alternating between left and right. Returning to the brush, she focuses again on her left nipple, eventually climaxing with intense moans—centered entirely on her left breast in a powerful, self-induced orgasm.
