I want to share a true story that happened to me recently. First of all I am a married forty two year old male and have taken enemas for erotic stimulation all of my adult life. I had been having trouble alternating between constipation and diarrhea for about a month and decided to go to the doctor to see what was wrong. I met with him and he decided I should have a Sigmoidoscopy the next week. The nurse gave me a preparation instruction sheet to follow. It said to eat nothing the day before the test and to drink a bottle of Magnesium Sulfate the night before. The next morning I was to take five Fleet enemas to clean out my colon about an hour before coming in to the office.

I had heard of the Sigmoidoscopy and basically knew it was inserting a flexible fiber optic tube all the way up into my descending colon. I had never had anything that invasive done and while it sounded a bit scary I was also fascinated by the thought of having to submit to such an embarrassing procedure. I started wondering exactly how they would do the procedure such as the positions I would be in and whether nurses would be there.

As the day before the test came I found myself getting excited over the prospect of being exposed and vulnerable while having my most private areas probed. I went to the drugstore and got a bottle of the laxative and instead of the Fleet enemas got a regular hot water bottle type enema set. I planned to give myself enough warm water enemas to get a clean expulsion just before I went in for the test. The night before I drank the bottle of laxative and later went to bed. The next morning I began taking a two-quart enema using a douche nozzle. I was really getting turned on by the enema and soon had a huge erection. I started masturbating while holding the enema and soon exploded in a huge orgasm. I expelled the first enema and could not believe the huge amount of feces that blasted out of me. I thought there could not possibly be anything left in me but three enemas later I was still expelling brown water. I was starting to wonder if I could ever get a clear return before I went in for the test.

I took a shower and went into the Doctors office. Soon after signing in I heard my name called and a tall brunette nurse about twenty- five years old met me at the door. My heart was pounding in anticipation at what was going to happen. She was friendly and we made some small talk while she checked my blood pressure. I was curious if she was going to be the Doctor’s assistant for the test. She led me back through a long hall and asked me if I needed to go to the bathroom before we got started. I told her that I did not need to and she motioned for me to come into an examination room. She closed the door and told me to have a seat. She stood across the room and asked me how the preparation had gone. I told her that I had trouble getting a clear return like the instructions asked for. I hoped she would take that as a cue to give me an enema and I was not disappointed.

She said that a clear bowel was important for the test and she would need to give me another enema just to make sure. The idea of this attractive nurse giving me an enema was making another erection start building in my pants. She told me to take all my clothes off below my waist but leave my socks on and get on the examination table. There was a paper sheet that she said I could cover myself with. She left the room saying she would be back soon. I took off my shoes, pants and underpants and sat on the table covering my waist with the sheet. I had a huge erection at this point and wondered how in the world she could avoid seeing the bulge through the small sheet.

In a couple of minutes she came back in and told me to lie down on my left side on the table. I pulled the sheet around with me covering my erection and lay down on my side. I could hear her behind me getting together some equipment but could not see anything. She must have used some pre-packaged enema because I never heard any water running. She came up behind me and asked me to pull my knees up to my chest. I felt her pull the sheet up exposing my behind to her.

I was hiding a huge erection and felt really turned on by being so exposed to her. She told me to bear down and I felt the tip of an enema nozzle against my anus. She slowly pushed it into my rectum and I heard a click as the solution started flowing into me. It didn’t feel like a lot of fluid and when it stopped I had no trouble holding it in. She pulled the sheet down over my behind and told me to hold it for about five minutes. She left the room and later came back in with a bedpan. She told me to expel into the bedpan and she would be back in about ten minutes.

I got down off of the table and squatted over the bedpan and started to expel. It came out clear this time and I knew this would be the last enema. I finished and got back up on the table. In a few minutes she came back in and looked in the bedpan and said that was good that I was cleaned out enough for the test. She left and said she and the doctor would be in soon. I had lost my erection by now and just sat under the sheet not knowing what was coming next. Soon she and the doctor came in and closed the door.

My doctor talked to me about the procedure but I kept noticing the nurse getting all of the equipment prepared. I saw her get what looked like a short metal tube out and squirting KY jelly on a small piece of cloth. My doctor said that he was going to first check me for hemorrhoids and then we would do the actual sigmoidoscopy. Then he told me to get up on my hands and knees with my feet off the back of the table. They both watched while the sheet dropped away and while nude from the waist down I got up and turned around. Now there was no hiding anything! My ass and penis were in full view and it was about to get worse. He started directing me to pull my knees apart and move farther down to the end of the table. Next he said to put my arms out in front of me and put my head down and turn it to the side. Now my ass was in the air and my penis hanging down in full view to both of them. I was humiliated but extremely aroused at the same time. I had never felt this combination before.

He asked me to bear down and I felt cold lubrication on my anus quickly followed by his gloved finger pushing into me. He quickly swirled his finger around inside my rectum and pulled it out. Next I felt both of his fingers pulling my anus apart as he said to push. I was getting another erection and I knew they could see it. It was incredible not being able to see them but knowing they were seeing everything I had.

He said "You don’t have any hemorrhoids outside lets see if there are any inside."

I felt something against my anus just as he told me to push again. A tube popped into me and I could feel him moving it in and out. I supposed it was the metal tube I saw the nurse with earlier. I knew now the he could see inside my rectum and the movement against my prostate was getting my erection harder. Surrendering to the all of these feelings was sending me into ecstasy. I knew this was supposed to be unpleasant but I loved it!

Next he pulled out the tube and my anus clamped shut. He told me to turn over and lay on my left side toward the wall. As I got up my still hard penis was dripping pre-cum as I turned over on my side while they both watched. She covered my legs with the sheet and told me to push my behind over the side of the table. As I did this he said to pull my knees up to my chest. I lay there totally exposed waiting for what would come next.

Soon I felt the tip of a fairly big object against my anus. I had to push down again as it penetrated just a short way into my rectum. He held it here as I heard air being pumped into my colon. I was not expecting this but the feeling of being pumped up like a balloon was very erotic. I could feel the smooth cool tube gently going deeper into me and the feeling of my anus gripping as it moved felt wonderful. Occasionally more air would be pumped in and if I relaxed my anus it would hiss out which I quickly clamped off by tightening my anus tighter around it. He said not to worry just let it out if I had to.

The feeling of winking my anus around the tube while they both watched was thrilling. I glanced back and saw the nurse standing and looking straight at my ass and helping with the lubrication. I wondered if she was watching me control the grip my anus had on the scope. Just the idea of her seeing me exposed and penetrated like this kept my erection up. Sometimes I felt a sharp cramp or poking all the way up near my ribs and it was hard not to flinch in pain. I was feeling pain, pleasure, humiliation, and turned on all at once.

Sometimes the scope moved in and out just slightly and rapidly and that was the best feeling of all. A couple of times I had to pull my knees up further to keep my legs from going to sleep. I knew that by now my ass and scrotum had to really be on full display. I could look at my penis and still see pre-cum dripping out on the table. Then he told me the insertion was almost done and that I would feel the end of the scope in a minute. I felt the conical end of the scope against my anus and knew it was all the way in. All of this lasted about twenty minutes and disappointment hit me as I felt the scope being pulled out. When it was completely out he had me sit up and I told them both that it was not so bad after all. Actually I loved every minute of it.

He gave me the results, which was simply irritable bowel syndrome and a sheet on how to deal with it. The doctor talked to me while the nurse cleaned up everything. He said that I was full of air and if I wanted to lie down on the table for a while and pass it I would feel better. They left saying to take my time, I lay back down on the table still turned on and erect and thought why waste the opportunity to cum again? I got back up and found the KY jelly and squirted some on my penis and got back on the examination table and started masturbating. I knew no one was going to come in but I could occasionally hear traffic in the hall. I pulled my legs apart and fingered my anus as I masturbated to a huge orgasm while replaying the whole experience in my mind. Then I cleaned up and left knowing this was the best trip to the doctor I ever had and insurance paid the bill!
