While walking near Shinagawa Station, I approached Riena as she was on her way back to work. She casually agreed to an interview, saying, "I still have some time, so let's grab tea or something." At first, our conversation was calm and relaxed, but gradually I steered it toward more sexual topics. Though slightly hesitant, she seemed to enjoy cooperating, growing more at ease as I removed her clothes and began fondling her breasts. It had been a while since she'd given a blowjob, but Riena shyly yet happily nodded when I asked. Removing her office-casual outfit revealed sexy sheer lingerie that took me by surprise. Seeing a working office lady in such erotic underwear while walking through the city made me instantly captivated. After taking off her panties, I started fingering her, stirring her wet slit as juices steadily flowed out. When I added a vibrator for more stimulation, she trembled and lightly climaxed while sucking my cock. Her pussy, now highly sensitive, tightly gripped my dick upon penetration, clenching rhythmically as if savoring the long-missed sensation. I thrust repeatedly into her slippery, aroused depths, finishing with a creampie. Although she had asked me not to cum inside because she had work, I accidentally did anyway—but she seemed satisfied, saying it felt good.
