"Rio" 23 years old, Height: 156cm, B:91 W:57 H:87, sports instructor living in Tokyo. Rio, who I usually match with on "Tin," is not only cute but has massive tits and works as a fitness instructor at a gym. Since it was raining, we headed straight to the room. Once we met, she immediately came across as cheerful and talkative. When I asked what kind of lessons she teaches, I found out she specializes in swimming instruction. Just imagining her in a swimsuit got me instantly turned on. She has the kind of body that looks like she's always wearing a competitive swimsuit, though she doesn't seem to mind. Most of her students are middle-aged men, although other classes include women—mostly older ladies with a "mature" vibe. Maybe because of that, she bragged about being popular with men. She has a boyfriend her same age, but they only meet once a week, and he's into vanilla sex. He likes being pleasured but wants long, satisfying sessions. However, he's quick to cum—whenever she tries to tease or tease him, he gets too excited and finishes too soon, leaving her unsatisfied. Her erogenous zones are her nipples and she loves cunnilingus and blowjobs. She gets especially sensitive when her neck is touched or licked, and once that switch flips, she's ready to go. Light touches make her react instantly, and when we talked about masturbation, she mentioned using toys. When she undressed, her huge breasts were perfectly shaped, her ass was perky, and her proportions were incredible. Her swimmer's physique clearly shows her body is well-toned. When I started masturbating her, I used a round stick vibrator on her neck, had her hold it, and subtly touched her—when she opened her legs, her panties already had a huge wet spot. Turns out she was turned on even before we started—definitely a horny girl. Switching from the vibrator to a Womanizer, she moaned, "Oh no, I'm gonna cum so fast~," her voice growing louder as she thrust her hips upward, climaxing hard with loud cries. Then, when I touched her nipples from behind, she smiled and moaned, "So good~," reaching her second orgasm. Laying her down on the sofa, I sucked her nipples, making her moan intensely, then went down on her with cunnilingus, capturing close-ups of her orgasmic face. Without pause, I fingered her, making her body twitch repeatedly as she came again and again. Finally, I inserted the Woman Vibrator while she still wore her panties—by now she seemed comfortable with the camera, lost in pleasure, completely absorbed. After that, I had her crawl on all fours and suck my cock. Once I was fully aroused, we changed positions—stripped her naked, admired her gorgeous tits, then sat in a chair for king-style blowjob. Her blowjob technique was amazing—her tongue wrapped around the head, sucking slowly and deeply with strong pressure, absolutely unbearable. Tit-fucking was just as good, drool dripping as she rubbed up and down, hitting all the right spots. After thoroughly enjoying her tits, we moved to the bed. I groped her breasts, sucked her nipples, teased her neck—her erogenous zones—then removed her soaked panties, now drenched with juice. I went down on her slippery pussy, stimulating her hypersensitive clit until she climaxed in seconds. I made her come again with fingers, then slid my cock inside. Starting in missionary, then switching to cowgirl, her athletic thighs and strong vaginal grip moved up and down, her face smiling as she enjoyed sex, clearly trying hard not to cum too soon. She urged me to thrust faster, taking pleasure into her own hands. Eventually tired, she had me suck her nipples while she enjoyed my hardest, most toned cock yet—she seemed so into it, so overwhelmed with pleasure, her joy naturally spilled into laughter and moans. After more enthusiastic tit-fucking, she rode me cowgirl-style, her athletic body on full display, grinding up and down with her pussy wide open. I shifted her body forward to change the angle, thrusting upward from below—she cried out, "So good~!" her moans growing louder, screaming "I'm cumming~! I'm cumming~!" as she had a powerful orgasm. Then, switching to reverse cowgirl, I enjoyed her peachy ass and hip lines, pounding into her as she shook her hips and climaxed again. After that, I took her doggy-style, then high-leg reverse, side reverse, deep thrusting, and finally finished in missionary. Bonus footage includes her self-shot masturbation and a POV blowjob with intense tit-fucking while staring into the camera.
