At this SOD sexology lab, Rika Yamamura, a serious female employee, will verify "what happens if we continue to leak body fluids from the whole body?" Researcher Yamamura experimented with his own body. When I was stimulated in the back of my throat with a 25 cm dildo and pierced my throat violently with Deep Throating, I was covered with Ezuki juice and was wrapped in an ecstatic expression. In addition, I squirted a lot with a super strong toy. At a later date, I received an impression that "it was the most comfortable", and the verification was successful.
