Mom never administered enemas when others were around ... but my sister and I got enemas on a regular basis ... mom (I think) would give dad the word that the enemas were going to be given, and he usually (mid-mornings on Saturdays, or early evenings on weekdays) would grab his hat and coat, tell us he had to go somewhere, or was meeting the guys for a beer and would be back after the ball game was done on TV ... thus mom and us girls had the house to ourselves for a few house.
Mom had a set way of doing things ... because we were alone, she simply told us to get undressed and come to the bathroom where she was preparing the enema solution, had the 12-ounce bulb syringe out (this was when we were pre-double-digits in age) ... we alternated on who was going to be first.
Mom would fill the syringe ... lube the recipient liberally including the inside of the anal channel ... lube the nozzle and then administer two to four bulbs filled with the soapy solution.
when she was done with the first one, then it was time to repeat the performance with the second one.
We both actually enjoyed enemas ... mom was gentle, held a running conversation about any subject available ... e.g. school, TV, boys ... any stuff like that.
When I got to be 10 years old, mom switched to the bag and hose ... this went quickly ... and, because we knew how easy it was go give enemas, we both administered on a regular basis after school to each other before mom and dad got home from work ... or many times we were just romp around the house naked ... we'd get rid our clothes when we got home and put them on again about a half hour before they were expected home from work.
I think mom knew we were taking enemas because she once asked if we were ... we said we were ... she said she wanted to watch us give each other enemas to make sure we were doing it right ... gave us a 'thumbs up" after a soapy enema and three rinse enemas each. She simply said, 'guess you don't need me any more' and that was the last time we ever got an enema from her when we were both home.
I did however, receive several from her when I stayed home from school because I didn't feel good.
Mom was always gentle ... I think she enjoyed giving enemas ... and I know we both enjoyed receiving them.
But they were always done at home, no other witnesses other that mom, me and my sister.
