The third installment in the Excretion Manual series features a full demonstration of women using male standing urinals, packed with excretion fetish appeal. Set in a scenario where women's restrooms are crowded, this video meticulously explains how females can use urinals designed for men. Most scenes begin with the women holding in their urine, resulting in abundant and visually striking urination. Bowel movements are also thoroughly covered, including enema use and deliberate defecation, with diverse depictions of excretion. Scenes are shot with up to five cameras, providing detailed, fetish-focused commentary. Post-excretion, intimate acts such as spreading the anus for wiping are clearly shown, heightening the sense of humiliation. As the women lean forward over the urinal to pee, urine splashes everywhere; soft stools and diarrhea drip heavily into the bowl, large amounts of loose feces gush out with a splutter, and open anuses release thick, continuous piles of poop—each moment captured in vivid, fetish-rich detail. Eight women in suits, school uniforms, casual wear, and yukatas slowly demonstrate standing urination and defecation, radiating shame throughout. From excretion techniques to aftercare, this is a fetish-filled guide to using standing urinals. (Haietsuya) ※ Faces fully shown
