Walking through a residential area in Shinagawa Ward, I noticed a familiar-looking sex worker. She appeared to be an ordinary woman, but something felt off—she was carrying both a large bag and a small bag together. Past 10 PM, she rang the doorbell and entered the last room on the second floor of an apartment building. The balcony's position was clearly visible, making it obvious where to gain access—something you couldn't easily do in a larger complex. She looked to be in her mid-twenties, with sharp facial features and a sexy mole near her lips. Her body was slender, with breasts around C or D cup, forming a shapely, well-proportioned figure. Her nipples were light pink, and her small areolas were incredibly attractive. The session began with a slow, deep kiss, then she moistly licked the man's nipples. An enthusiastic, highly service-oriented girl—truly enviable. I wondered which shop she belonged to. During cunnilingus, she twisted her face in sensual delight, writhing her body. Her sensitivity was excellent, extremely erotic. After brief foreplay, the man put on a condom, and she revealed herself as a full-service girl. Missionary position performed in the "Daishuki Hold" was incredibly generous—almost too much. Was this sex worker a real enthusiast? In cowgirl position, she alternated between deep kissing, piston-like thrusting, and grinding movements. The scene lasted quite long, thoroughly satisfying. Her faintly visible abdominal muscles and nowadays-rare pubic hair were irresistible. After doggy style, she finished with nipple teasing blowjob, followed by nipple-sucking handjob—deeply erotic. I briefly considered tailing her further to uncover her shop, but after she disappeared into some building, I realized I couldn't identify her workplace and snapped back to reality. I sprinted toward a nearby brothel, hoping to still make it in time for a 30-minute session.
