My three girl cousins, I do not know about their brother who was much younger than we were, got their enemas kneeling on a bathmat and leaning over the side of the bathtub. They received their enemas individually and privately, whenever my aunt felt they needed one, which was quit regularly. Though it was done in private, it was no secret when one of them was being given an enema.
The oldest of the three girls, who was the closest to my age, told me the details of how their mother gave them enemas. As you can imagine, I worked the conversation around to the subject of enemas and got her to describe the process and her experiences every chance I got. The details varied very little form one time to another.
If their mother had already planned to give one of them an enema, She would simply tell them, to come with her and she would lead them down the hall, through the mater bedroom and into the large private bathroom at the back of the house. The intended recipient of the enema would have a pretty good idea what was coming as soon as she was told to go with her mother in the direction of her parent's bedroom. When they got to the bathroom, she would see the empty red, two-quart enema bag already hanging on the shower curtain rod, the big glass picture with a bar of soap sitting in the bottom of it would be on the vanity beside the sink.
Her mother would tell her, "You will feel much better (not that she had complained) after I give you a good enema. We will see how the first one goes, and then decide if you need more than one." My aunt would then turn on the water, to let it get hot, and tell my cousin to undress, as necessary depending on what she was wearing, and get into position leaning over the tub. By the time her enema was ready, she would be in position and waiting. My aunt would first wet and lubricate the enema tip with soap, then she would loop the hose over the top of the enema bag, so that the tip was hanging free. She would then spread my cousin's buttocks with her thumb and fingers of her left hand and smear her anus with soap. Her mother, still holding her cheeks apart would insert the enema tip and start the flow, holding the tip in with one hand and controlling the flow with the other. My cousin said that my aunt always let it go in fast at first, until she complained that it was too much, then slowed it down for the remainder of whatever quantity was in the bag. My cousin did not know how much soapy water her mother gave her, but said that it was a lot and that if she could not take it all, she knew she was going to get more enemas until she could take the whole bag.
The main variation to the process described above, occurred when the enema was not preplanned by my aunt. That is, if one of the girls complained of a tummy ache or constipation or other "need" for an enema. Then, they would be taken to the bathroom and, if an enema was deemed in order, the process began with getting out the bag and pitcher. Occasionally, and I do not know what determined this, rather than receiving an enema, the child would have a suppository inserted and be told, "Go lie down on Mommy's bed until you really have to go, and then to sit on the toilet and hold it just as long as you can. Mommy will be back to check on you in a little while."
Interestingly, I think, the cousin I am speaking of, who is a couple of years younger then I am, did not seem to find anything embarrassing or erotic about the enemas she frequently got. They were just a normal part of her routine. She did, however, realize that talking about them aroused me. I would not have the nerve to broach the subject now, but I would love to relive some of those conversations.
