Meeting up early in the morning in Tokyo. I had been in contact with Ayumi for three weeks, but I was worried whether she would actually show up. Then, right on time, my phone rang with a message saying, "I've arrived." She safely came up to Tokyo from City S by bullet train. She was smaller than I expected from the photos she sent, with fair skin and a quiet, ordinary girl appearance. But during our train conversation, she wasn't shy at all—she spoke clearly and confidently, which I found very appealing. She's 19 years old, an only child, and although she had always been curious about men, she'd never dated anyone before. However, after losing her virginity, she changed dramatically and now thoroughly enjoys sex. Her partner count exceeds three digits, almost all of them regular male friends, whom she turned into "cunt brothers." She's a full-blown sex maniac—by weekends, she feels like "it's not over unless we have sex," and sex has become an indispensable part of her life. One day, she was invited to karaoke by a male friend, but when she arrived, there was another guy there too. Without even drinking, it quickly turned into a threesome. Before she knew it, the number of men had grown to eight, with others waiting in line. Laughing, she said, "It was kind of crazy," but added, "I really enjoyed it" and "It was the most pleasurable I've ever had," speaking about it as casually as if it were an everyday event. She has a natural submissive side and gets turned on by multiple partners and sex in tight spaces. When asked about being filmed, she immediately replied, "I'm fine with it." She enjoys hanging out with guys her age and quickly clicks with anyone she vibes with. She talks openly about her past sexual experiences too. When hugged from behind and kissed deeply, having her pussy teased through her underwear with fingers and tongue, she moans, "Aaahn, nooo~." When given direct cunnilingus, she grips the man's hand tightly and spreads her legs wide, begging for more. In the 69 position, she sucks skillfully with rhythmic head movements and handjob techniques, making loud slurping sounds, and perfectly licks the balls at just the right moments. She says, "I want it inside—cowgirl is good," guiding the cock with her own hand into her pussy, moaning, "Aaah, so good! Aaahn, no! N-not there, that spot!" She loves checking that it's actually inside, touching the thrusting cock and her clit while moaning. Then, getting pounded harder in doggystyle, she makes obscenely twisted facial expressions. In missionary position, she greedily stimulates her own clit with her hands, chasing pleasure. Finally, with a pillow under her hips for the perfect angle, she screams, face bright red, "Nooo, stop, I can't, I can't anymore!" as she's relentlessly pounded. At climax, she stares intensely at the cock shooting cum all over her stomach. She says she'd love to be with multiple men again sometime. Although she's had countless sexual encounters and sensory checks, she hasn't experienced much deep or intense sex. She's not used to slow, meticulous teasing, so during her first experience of restrained, quiet stimulation, she shows a confused reaction mixed with embarrassment and excitement. Her nipples become hard and erect, and when a vibrator is applied to her clit, she impatiently says, "More to the left!" Once her hands are freed, she grabs the vibrator herself and enthusiastically fingers her soaked pussy, screaming, "No no no!!!" while enjoying messy handjobs. "Aaah! Aaah! I'm cumming, I'm cumming!" she shrieks. She started masturbating after her first time, when her interest and libido exploded after having sex. At first, she didn't take off her underwear and enjoyed the sensation through the fabric, but now she loves using vibrators. She has sex twice a week, almost always with friends. For her masturbation sessions, a fixed camera is set up in a room of her 3LDK apartment (Room 202), and she masturbates naturally with no time restrictions or instructions. When she's done, she calls someone from Room 201. The footage includes her entire cleanup afterward. 28th HOUNAI.
