Because Shinozuki and her boyfriend had sex for the first time the day before, the condom came off midway, and because of the unknown pain for the first time, they were afraid of getting pregnant and went to the hospital for a checkup. At first, the doctor was very friendly and took her blood pressure. He used a stethoscope to listen to her heartbeat, and then used a small curtain to cover her belly for a closer inspection of her lower body. Unexpectedly, the doctor actually picked up a massage stick and touched her lower body with his fingers, and even more while Shinozuki continued to climax. He thrust his cock further into it and thrust it for a while.
