By the time I was about 9 my mother worked, and I would be home alone after school for a couple of hours.
Because I had been given enemas, and I loved them, I knew where the Davol open top bag was kept. So a couple of afternoons a week I would give myself enemas. I just kept doing them until it was getting close to when my parents came home, so I would take as many as time would permit.
Usually, by the last enema what came out was clear water.
My norm was to need to have a BM when I got home from school, and I already knew enemas felt best if I already had to go. Most days I could take the entire two quarts no matter how strong the urge had been. In fact to feel a strong urge to poop made the enema even better, that struggle to get it all in.
There were probably days I did as many as 8 or 10 enemas, but the feeling was never as good as when the chunks were flying. Being an adventurous type I learned to make balls of toilet paper and shove as many as a dozen or more inside, do an enema, catch them on the way out and do it again. Even with the enema they would pick up a nice coating of mucous, so I could slide them in easily.
I never got caught, but did get some comments about using so much toilet paper, I think one time when I was really into seeing how many I could get inside me I used an entire roll.
So to this day, toys or enemas, I love things shoved deep inside, and some of the silicone nozzles available today are a big turn on. I find it really erotic and exotic to get one all the way across the transverse colon and either use an enema while sliding it in, or better still filling to capacity while it is all the way across to my cecum.
Creates a super orgasm, and fun deciding to hold it in while expelling or letting it come out and enjoying the sensation of reinserting it.
What is even better, even though she would never admit to it being sexual, I have found a colon therapist willing to do the colon tube insertion and enema. I was open and honest about my feelings, and she is fine with doing the insertions. No, I still have to do my own happy endings, but the insertions are awesome.... always better when someone else is doing It!
