The only child or teen to give me an enema or get an enema from me was my sister. But when I was about a sophomore, my BFF and I had an enema together although we just watched each other without actually giving it to each other. The situation was all day at school I felt "shitty" and decided a small enema when I got home would do me good. There was about two hours time available until mom got home from work, and I sometimes did that. My BFF lived two houses down and we often spent that time at my house doing homework or just hanging out. That day as we walked home I told her I had to do something first and she should come over later. She said she would just wait while I did whatever it was I had to do.
I told her she could watch TV or something and I would be done in a few minutes. But she followed me right into the bathroom. We often went to the bathroom together and had seen each other naked, so I told her straight out that I needed an enema. She did not leave but sat on the edge of the tub as I ran the water to warm it and got out the bulb. I dropped my jeans and panties, lubed myself, and gave myself two or three squirts while standing at the sink. She watched wide-eyed but silently until I sat on the toilet and the water and shit came gushing out. Then she started asking questions. Obviously she had not had an enema before. How does the water feel going in? Coming out? I wiped and went back to the sink and I gave myself a couple more bulbs. Then she asked, "What happens if you have an enema when you are not constipated?" I told her, "Nothing, then just plain water comes out."
I refilled the bulb and held it out to her. She hesitated a bit but then her jeans and panties were on the pile with mine. As I sat on the toilet I told her how to lube her butt-hole, insert the nozzle, and squeeze, holding it squeezed while withdrawing it. You should have seen her face! She gave herself two bulbs and immediately ran to the toilet. She was surprised how much shit came out even though she did not feel like she needed to go.
We did not talk about her first enema immediately but I wondered if she enjoyed it or not. The answer came about a week later when we were deciding what to do since we had no homework for the weekend, she asked, "Can we do that enema thing?"
