I got occasional enemas standing up. As I recall, they were done if for some reason we were in a hurry, or had to be somewhere soon, and my uncle just felt that I needed an enema before we left. So, he would take me quickly into the bathroom, and remove my clothes, and have me stand bent over while he lubed me and then he inserted the enema. Sometimes he used the higginson pump, but mostly he had the enema can filled and he just held it up over my head while I filled up. I did not like this kind of enema, as it seemed to run in too fast. With the result that when I was younger, say 5-8 I would be spanked and then given the enema anyway. He often was seated on the toilet while I stood in front of him, with him holding me so I could not move too far. At the conclusion of the enema, he would remove the nozzle and sit me on his lap, while he massaged my tummy. I do remember once or twice making him angry by my complaining, and this resulted in finishing the enema with a spanking over his lap while trying to retain a tummy full of water. He also occasionally would apply rectal dilators to my bottom to help hold in the enema, or in the case of me getting it standing, would just use his finger.
I probably did not get as many punishment enemas, but mine went this way: I was taken to the bedroom and undressed, and then stood in front of my uncle who recounted what I had done wrong, and then explaining to me in detail why I was to be punished. I was then spanked, naked, over his lap, until I was screaming for him to stop. I actually would beg him to stop spanking and give me the enema (The enema was part of the punishment)! He would stop, and then still blubbering and crying,, was taken in to the bathroom, put on the counter, legs up, and had a hot soapy enema administered. I was then stood up in front of him and had to "apologize" for whatever it was I had done--before I could let the enema out. Often I was pulled back over his knee and given a few hard spanks to make my bottom really sore and many times this was done while I was still holding the just given enema ---so, it hurt just to sit on the toilet.
