SOD Sex Science Lab, which seriously studies sex. This time's theme is "intestinal juice". A thorough report of cleaning, dilation, enema, and anal sex performed by a female researcher who used herself as a subject. Even though her face turned pale, she bravely participated in enema, AtoM, and 3-hole fuck experiments, and made full use of the entire area of SOD's headquarters to record a research record of a total of 15,000 ml of intestinal juice.




















*A beautiful older sister appears. In terms of content, I'm doing a lot of enemas, but it's pretty good. I think this is an irresistible development for enema lovers. My plump body gets excited again. I would love to see a sequel with the same actress! It was a really good piece of work.
*This is SOD's specialty, a gap attack. There are many works in which a woman who simply loves anal has anal sex, but this work succeeds in juxtaposing serious research purposes and obscene anal sex, three themes that would never be able to coexist in the reality of being the subject, on the same stage.
*This is my first time seeing Motoko Motomura. Volunteered to become an anal expert. A thorough report on anal cleaning, dilation, enema, and anal intercourse. Cute face? But her face is erotically cute when she's working hard on anal. Looks fun, feels good... She has a pigmented anal ring and an obscene anus. I want to lick it, put my tongue in it, and fuck my cock. Intestinal juices will overflow along with the enema fluid. It's actually eun soup. I put the cock in her anus raw, then pull it out, put it in her mouth, put the shitty cock in her mouth, and put it in her pussy as well...I can't stand it. This is a recommended work for analists. I was swamped by Motoko Motomura's butthole.
