We are an adult toy manufacturing and sales company constantly engaged in product development, so we regularly recruit monitoring staff. This time, we feature Yui, a 30-year-old slender and beautiful older woman who agreed to cooperate in testing our products. On the desk were popular items like vibrators, electric massagers, and dildos. Yui said, "I've never used these before." She was then asked to pick her favorite item and try it out on the sofa in the back. She chose a popular vibrator. Sitting on the sofa, she placed the vibrator directly on her bare nipples. Moaning "Haaaauuuu…," she fondled her breasts while stimulating her pussy with the vibrator. She removed her panties, exposing her completely shaved pussy, and pressed the vibrator against her clit, making her hips twitch uncontrollably. A staff member entered, watching her and exclaiming, "You look amazing." Yui replied, "I'm so pent up…" while showing off her rock-hard, erect cock. The staff asked, "Can I touch it?" but she refused with a "No," leaving him denied while she continued masturbating with the vibrator, eventually allowing a handjob. As her breasts were groped and her nipples sucked, fingers penetrated her pussy, making her writhe her hips and cry out, "Haaaauuu, I'm cumming!" Stimulated by the vibrator, she squirted, and her salty pussy was licked intensely with cunnilingus. On all fours, she thrust her ass out, climaxing repeatedly from finger penetration. Yui pleaded, "I need it now…" and began sucking the large cock. Hands-free, she deepthroated it, repeatedly licking the underside of the shaft, delivering an intense, skilled blowjob. Lying on the sofa, she received fingering while being deep-throated, her pussy spread open with her hands. "Please… put it in," she begged, turning into a submissive female dog, cumming just from the cock rubbing against her clit. She kept saying, "I want it inside," mounting the cock in a face-to-face seated position, grinding her pussy against it before fully impaling herself and pounding repeatedly. When the cock slipped out, she leaked fluid uncontrollably, her sloppy pussy thrust upward from below with deep, wet strokes. Doggy style made her swing her hips, then standing doggy slammed into her with loud, hard thrusts—never stopping even after she came, relentlessly pounded from behind. Switching to missionary, her shaved pussy was thrust into repeatedly, then changing angles to side position for fierce pounding. The climax came with a cumshot splashing all over her beautiful breasts! She cleaned the cock with a blowjob, and the session concluded with, "The monitoring survey is now complete. Please share your feedback." The lustful older woman Yui, who squirted repeatedly, is now an active core product tester for our company. "Similar to Uni Shiokawa#"
