I thought about this 'posed situation' for a while, even called my sister because we not only got enemas together in our pre-double-digit age era, and then did them together with each other after mom taught us to self-administer, and there really wasn't at any time (we agree on this) anything we ever vigorously disliked about enemas ever.
Yes, we did our share of whining and complaining when mom would announced "it's enema time" ... we knew it was coming because she only gave us enemas when dad was gone for a prolonged time so we were never afraid of him stepping into our scene.
When she said 'it's time', we just naturally headed for the area of the bathroom, undressed, waited patiently as she prepared the soapy solution, did some whining, were told to pipe down or we might end up getting a spanking too (note: Neither of us ever got spanked in our lives), obeyed mom's commands when she was ready to administer ... she liked to have us standing, bent over with our hands on edge of the bathtub ... we liked that too ... and she was always nice about the size of the enemas -- the first one was usually a quart, second soapy one two quarts, then two or three rinse enemas --- and each was done without rushing or any urgency. She made it a relaxing, enjoyable experience. (I think she knew we didn't dislike enemas)
When we were done, she never encouraged us to get dress (I think she also knew we like go around tdhe house naked) and when she thought it was about time for dad to arrive home from whatever he was out doing, she's say "Girls, time to get dressed", and we would.
When we were in junior high and senior high school, we'd usually arrive home a couple hours before both got home from work ... the clothes were gone before he got to the living room ... we did all our activities naked including homework ... but sometimes we'd suggest our own little enema-fest.
Oh yes, no one else new about our enemas, our personal sessions and other other activities between the two of us. We never had friends over to the house when mom or dad were not there ... it was their major rule and we didn't violate it because who would want the good thing we had going.
So, to sum up our answer, there's nothing we ever dislike about enemas ... and that still holds true to this day, nearly 30 years after mom administered them.
