The SOD Sex Science Lab is a serious sex research lab. This time the topic was "Bowel Fluids". A female researcher gave a detailed report on cleansing, dilation, enema and anal sex using herself as a subject. Even though she was pale, she bravely completed experiments such as enema endurance, AtoM, and three-hole sex, and made full use of the entire SOD headquarters to record the results of her research, which spewed out a total of 15,000 milliliters of intestinal fluid.
