Meeting up at Shinjuku Station is a current female university student about to graduate, Rio, 22 years old. She openly admits, "I stopped counting my partners a long time ago—probably around 100 by now," and shows her honest, carefree promiscuous attitude with a simple "As long as it's fun, it's okay." Currently on spring break with plenty of free time, she's been focusing on her part-time job as an esthetician. Rio has a mischievous, teasing personality, admitting she enjoys making her partners impatient. When requested for a treatment, she responds with suggestive, borderline techniques, subtly pressing her soft, jiggly G-cup breasts against her client to intensify the allure. Her skilled esthetician hands deliver a rolling handjob, while her blowjob technique thoroughly pleases every part, even giving special attention to the balls—this is true promiscuity at its finest. As she kneads her oil-slick, massive breasts, her pussy grows wet and slippery. When her aroused pussy is stimulated, a heavy gush of female ejaculation pours out. Fully prepared, she takes the cock deep inside with a wet thrust, yet teases, "Don't cum yet," heightening her devilish charm. A creampie is followed immediately by relentless toy play, triggering an unstoppable flood. Of course, it doesn't end after just one round—actually, the real action begins in the second round? The promiscuous girl, now fully turned on, continues with aggressive fucking, finishing off with cleanup titty fucks and blowjobs for perfect aftercare. Rio's passion and charm are unforgettable once experienced.
