In the evening in Higashi-Shinjuku, we approached an office lady returning from work. As usual, we explained, "We just need you for a quick interview..." and smoothly invited her to a nearby hotel—an easy transition, as she didn't refuse. Meet Rinn, a 24-year-old working at an IT company as a project manager, handling everything from sales to project coordination. She looks slightly tired, and admits she hasn't had a boyfriend for about two years. When it comes to sex, she sticks to the rule of only doing it within a relationship and has never had a casual sex partner. With only three sexual partners in her life, she seems relatively inexperienced—but surprisingly, she masturbates around three times a week. When we playfully applied a vibrator over her pantyhose, she quickly let out pleasurable moans. Clearly, she's been holding back. Pulling aside her pantyhose and underwear, we licked the clit barely hidden beneath her light pubic hair, and immediately, lewd sounds accompanied a flow of wetness from her pussy. It had clearly been a while. When we presented our cock, she happily grabbed it, her eyes sparkling as she whispered, "Big!" She coated the head with saliva, swirling her tongue around it before sucking the shaft deeply, savoring every inch. It had been two years since her last sex, so she climaxed easily. With intense rear-entry thrusting, her ass jiggled with loud "slap, slap" sounds, and she quickly screamed, "So good!!!" But one orgasm wasn't enough—she mounted us in cowgirl position, grinding her hips and chasing multiple consecutive orgasms. This serious, hardworking OL turned out to be a lustful woman, secretly craving cock to relieve her pent-up desires.
