A rare documentary capturing women experiencing intense, unbearable urges to defecate, filmed over an extended period to authentically portray their limits. The footage shows women struggling with overwhelming bowel pressure during preparation, waiting periods, and even during urine-focused shoots, reaching their breaking point. Detailed close-ups depict sphincter relaxation, gradual fecal protrusion, and the moments just before full defecation. This milestone release commemorates OJHI's 500th catalog number, offering an intense, must-see viewing experience. [Shinobu] A lovely beauty whose anal opening reveals a protruding fecal head; her sphincter fails, forcing her to clamp down with buttock pressure. She exclaims the expelled monstrous stool is "the biggest in my life." [Yuri] Her towering pile of feces—so impressive it's compared to the pyramids of Egypt—contains visible undigested food remnants like grains. [Suzu] Adorably squirming in the dressing room, she shyly thrusts her bare buttocks toward the camera, feigning embarrassment. Soon after, she violently sprays thick diarrhea, flooding the floor into a watery mess. During a urine-holding session with orgasm denial, she suddenly feels an urgent need to defecate. After intense anal contractions, she releases a long-accumulated, fist-sized mass of feces from her colon. Produced by Haieshoku-ya. Full facial exposure throughout.
