At this SOD sexology lab, a serious female employee, Tsugumi Baba, will verify "what happens if we continue to leak body fluids from the whole body?" Baba was stimulated in the back of his throat with a 25 cm dildo, and when he was pierced violently by Deep Throating, he was covered with Ezuki juice and was wrapped in an ecstatic expression. I squirted a lot with a powerful toy. At a later date, I received an impression that "it was the most comfortable", and the verification was successful.
