This work begins by secretly giving laxatives to women participating in panty photo shoots. Over time, the tension builds as they are asked probing questions centered around the theme of "what is embarrassment?" Once the urge to defecate sets in, the women are led toward a specially prepared traditional Japanese-style toilet. This toilet is equipped with hidden cameras, allows voyeuristic viewing via a two-way mirror, and features an extremely perverted mechanism designed to collect excrement after flushing. Before entering, each woman is asked to confirm whether she will only urinate—but many end up defecating as well. Then, suddenly, they are confronted with the shocking sight of their own previously consumed feces. How will they react? One adorable girl with apple-like cheeks immediately leaks urine upon reaching the toilet. After a long, drawn-out urination, another elegant lady squats down as her anus swells dramatically, releasing an impressively thick, massive log of feces. Her demeanor shifts completely from poised and graceful to intensely strained, her face contorted as she forcefully expels an enormous, rock-hard mass of long-accumulated waste from deep within. Meanwhile, a more down-to-earth older woman lets loose a barrage of loose, diarrhea-like stools accompanied by crude, squishy sounds. After the women leave, the staff retrieve the flushed feces and thrust them back in front of each woman’s face. One particularly lovely beauty, whose delicate appearance makes it hard to imagine such a scene, ends up producing an unimaginably thick, meaty turd. When staff check to see if any residue remains uncleaned, unexpected results leave the women blushing in surprise. Packed with humorous and erotic depictions of excretion, this is the full-face-revealed main feature from "Defecation House."
