Could never tell but I think so, as she always had the enema bag with hose and nozzle promptly displayed in our main bathroom for any guests to see, but some neighborhood kid's parents had the same thing, and I would visualize friends like Mary or Ron getting an enema from the ones I saw when using their bathrooms. Growing up in the 50's / 60's, seeing this was familiar. Onto my thoughts…
After getting older and not fighting, fussing, or crying over my getting an enema, ( started to enjoy them ) Mom's disposition changed. Once told that I needed an enema and required to get naked in front of her, and assume the position she wanted, everything changed. After that she became so sweet.
By this time around 8, I was either made to get in the knee chest or diaper position. In either case, she saw my erection that these enemas caused, as once while in the diaper position and her sitting on the closed toilet seat, I could see a dark wet spot in her panties. All the while me with a raging hard on that I tried to cover up with my hands. In this experience she told me that boys sometimes get erections from an enema, and it was natural. During knee chest positions, I know she could see my erection but didn't say a word, as she would lean over and softly rub my belly where on occasion, would brush up against my still cock while telling me what a “ good boy I was” , and encouraging me to empty the bag for her.
Emptying was another thing, as she took her time to either get another bag ready for me or just cleaning up after my rinse enema, as there was never just one. Meanwhile she took her time as she heard my expulsions and plopping of turds into the bowel, along with an occasional glance, and smile towards me, asking if I felt better, or needed another? Hindsight is 20-20.
She would hang the bag and hose out to dry separately on the towel bar while I expelled, but on many occasions after being sent to bed, I would find the enema equipment hung out on the shower curtain rod the next morning, as I usually got up before her after one of her sessions. I visualized my Mom doing an enema to herself, but even when I got older, I never had the nerve to ask her.
My Dad was always on the road and Mom was alone a lot, so yes… I think she got off giving me, or her doing an enema(s) after.
