Tamako visits the hospital after not having a bowel movement for three days, feeling a bloated stomach during class.Dr. Kagami, a new female doctor, begins examining Mako under the guidance of Director Higashimoto.She takes off Mako's skirt and lays her on her back on the examination bed and begins massaging her lower abdomen.By pressing hard on her colon, her intestines become more active, and you can hear the sound of moving stools coming from her belly.She is made to take her posture on all fours on her examination bed as it is and an anal massage by Dr. Kagami.As she relaxes her pussy and carefully strokes her anal wrinkles with her fingers smeared with a large amount of petroleum jelly, a sweet sigh escapes from her lips.Slowly moving her finger back and forth in her anus, her breathing becomes rough.Mako who is pressed in her rectum by her teacher Kagami's fingers and stimulates her bladder, resulting in urinary incontinence.I can see her rectal activity, so I let her breathe on all fours.Her anus swells and rolls up every time Mako puts in her power.By applying force to her lower abdomen, Mako becomes urinary incontinence again.Little by little, a brown object comes into view from her anus, which expands and contracts repeatedly.Small, hard stool masses fell on the water-absorbing sheet spread on the examination bed in multiple batches.A urinary catheter is used to check whether there is any abnormality in Mako's bladder due to urinary incontinence during anal massage.The tip of the catheter reaches the bladder, and dark colored and fragrant urine drips into the glass container.Continued palpation of the rectum by the director who is a veteran of the anal examination.Laying her Mako on her back, holding her knees, and taking a crushed stone position, an anus like a small bud was exposed.By catching a man's thick finger in the anus, sexual pleasure occurs in Mako and sweet panting begins to leak.Since it is also for the purpose of anal expansion, if you increase the number of fingers to two, Mako's gasping will become intense and the anal sphincter will tighten the fingers strongly.Director Higashimoto's finger moves faster as Mako's sexual response increases.At the same time as panting reaches its climax, it splashes urine like a fountain.Moreover, mixed with urine, the white mucus overflowing from the vagina accumulates in the director's palm.Next, using an anal dilation bougie to expand the anus and check the anal sensation.It gradually changes from a bougie that is thinner than a little finger to a thicker bougie, and finally stimulates Mako's anus with a bougie that is thicker than a thumb.In order to check the remaining stool in the intestine, I inserted an anoscope and widened the anus greatly, and I was able to confirm that there was a stool mass remaining in the back of the rectum.Kagami-sensei recommends an enema to cleanse the bowels of Mako, who complains that her stomach is not feeling refreshed.A special enema with a wide nozzle hole that is inserted into the anus, and by adjusting the height of the irrigator, lukewarm water flows back and forth between the irrigator and the rectum.The 500cc of warm water that flowed into Mako's rectum returns to the irrigator by lowering the position of the irrigator.By repeating this, the lukewarm water, which had been transparent, gradually turned brown.Wear disposable diapers to hold off excretion.Mako tried to put up with the embarrassment of defecating in a diaper, but she immediately excreted a cloudy liquid with a loud gurgling sound.A brown liquid seeps into the white paper diaper.As the final stage of bowel cleansing, 1000cc of tepid water is given as an enema, and the bowel is washed by repeatedly excreting it several times.It seems that the amount exceeded the limit of Mako's body, and brown and muddy liquid flows back into Irrigator.Mako's patience seemed to have exceeded the limit, and the moment the anal nozzle was pulled out, the anus collapsed and the turbid liquid spouted out.
