I have taken and given enemas for many years. I also have a number of colonics. From time to time I have had both combined in one session. Several years ago I saw an older lady who ran an ad for colonics and visited her. She was in a wheelchair, but was a really no nonsense type of lady who insisted on a large volume enema with a colon tube, prior to going on the machine. She said that the enema "loosened things up," and made for a better release.
The process was to get undressed, and meet her in the toilet. She then instructed me to get on my hands and knees in the tub, which had a padded rug laying in the bottom to kneel on. Hanging on a hook was a 4 quart enema bag full of warm water connected to a long colon tube. She rolled up to the tub, lubed the tube, then slowly inserted it the full length (about 36") while running the water in. She seemed to pay no attention to my erection, simply kept the water flowing while massaging my stomach. When I could take no more, I had almost all of the water in me, she slowly pulled the tube out, again not paying any attention to the pre-cum dripping out.
Once the tube was fully removed, she pressed some toilet paper to my anus and told me to go to the next room and get on the table on my back. She followed, rolling right up to the end of the table, and had me pull my legs up toward my chest. She quickly inserted the rather large speculum and connected me to the machine. I was quite surprised that there was not much leakage as she made the connection. Once on the machine, she gave me a quick blast of cool water, turned the valve and I released a huge amount of water and waste. The pressure resulted in me ejaculating, which she simply dealt with by handing me a wash cloth to wipe up with. The rest of the colonic was as usual, with several fills and releases. The last fill was held and expelled on the toilet.
After expelling I was a little light headed and she insisted that I sit in the living room (she ran the service out her home which was a double wide mobile home) and drink some sort of vile tasting health drink to replace the electrolytes that I had lost.
While sitting and drinking the liquid, her next client arrived which was a rather large lady in which I would guess as being in her forties. Knowing that there was no curtains in the hallway, I feigned a bit of dizziness. She said to stay as long as I liked, until I was feeling better and she would attend to her next client.
I stayed where I was, and listened to her small talk (it seemed that this lady was a regular), and I could hear her running the water to fill the bag. I waited until she was in the bathroom, then moved over on the couch so I could see down the hallway. In about 10 minutes, I could hear the lady say, "that is enough, I cannot take any more." Shortly thereafter I saw her walk out and down the hall. She was fully naked except for her bra, and she was holding the tissue paper between her cheeks to keep from leaking. She was followed by the therapist, rolling along in her wheelchair, saying that she was doing quite well and had taken the largest enema so far, almost a a full four quarts.
To this day, that session was one of the most memorable. combining many fantasies that had developed in my rather young mind. The thought of the big lady on her hands and knees with the big red colon tube filling her, provided fodder for many ejaculations over the years.
unfortunately, the next time I called for an appointment, I was told by someone on the phone that she had passed away and the business was closed. A pity, I could sure use one of her treatments today.
