Mom, as a rule, gave us enemas in the bedroom together, laying across our bed. That being said, she did give us enemas in private, every once in a while, in the bathroom. It just depended on the situation, and circumstances at the time. One of those being, after she gave one of us a spanking, laying naked across her lap in the bathroom. Then, there were her unexpected enemas on rainy days, that weren't really necessary.
Those out of the blue enemas, usually happened on rainy days, when we had to play inside. They started, when I was around eight, and continued until I was ten.
Looking back, I think a couple of things were going on.
1) In the beginning, mom was just trying to increase the enema volume we could take and hold during normal enemas. Not only was she doing it, but so were her two younger sisters. Something, our RN grandmother may have suggested they do, because we'd started having more constipation issues around that same time.
2) Giving us enemas was turning them on. Around that time, when our two young aunts gave us enemas at bathtime. It was getting obvious; they were getting turned on giving us enemas laying naked across their bare lap. Like us, both girls were naked, because they got in the large walk-in dual head shower to keep order and bathe us. With two teenage girls, in the shower with us, it didn't take long to realize something was going on. I realized later, as a teenager, why the girls were getting so giggly when they gave us enemas. As teenagers, when my sister and I gave one another enemas, it turned us on. So, I suspect, it wasn't any different for the girls, whenever they us enemas laying naked across their lap. Nor do I think, it was any different for mom, when she gave us enemas. Tho, she was never naked, like her two sisters. She had a sheer nightgown on, that we could see through. Making it easy for us to tell, she wasn't wearing a bra or panties.
My siblings and I didn't have issues, about being given enemas, even from an early age. So, by the time mom and our aunts started give us enemas, that were other than routine. We never fussed about it, in fact, we rather enjoyed it. To us, the unexpected rinse enemas, were more pleasurable than routine soapy and rinse enemas.
