[SDJS-336]

SDJS-336 SOD is a serious sex research facility. This time, “intestinal juice” is the topic. A thorough report of cleaning, dilation, enema, and anal sex performed by a female researcher who used herself as a subject. Even though his face turned pale, he bravely participated in enema, atom, and three-hole fuck experiments, and made full use of the entire SOD headquarters to record a research record of a super injection of a total of 15,000 ml of intestinal juice. – Jav.wine SDJS336
