I got a first-year female college student!! "We'll offer compensation, would you be willing to assist with the research and development of a bidet toilet seat?" I asked her to take on a simple part-time job. Yuuka-san, who specializes in medical studies, is a charming beauty with an unending smile. "If it's just showing my butt hole, haha," she revealed her beautiful anus wide open, leading to an immediate anal research. Measurements were taken of the color, size, progress rate, position, etc. of the anus. To recreate the gentle water flow of the bidet toilet seat, the anus was stimulated with the tongue for anal research. After the anal research, she moved on to the penis (o●ko) study, with her nipples' sensitivity rapidly increasing↑. She skillfully presented her mouth in front of me and gave a blowjob, so as a thank you, I deeply penetrated her raw.
