When I was about three or four years old I was next door playing with a little boy who was still in training pants.
His aunt kept him while his mother worked. We had a pile of small toys on the kitchen floor having a wonderful time when his aunt walked by, scooped him up and started carrying him into her hall bathroom while removing his training pants. I followed but stopped at the doorway and watched.
She turned him upside down on her lap and reached for a small bulb syringe floating in a basin full of soapy water.
I had enemas from my mother so I knew Jimmy was fixing to get a lot of soapy water injected into him rectum.
Auntie injected three or four bulbs full before sitting Jimmy on his potty chair where he promptly expelled his first enema.
When he finished, Auntie repeated the fillings while Jimmy giggled and said, more, more.
Auntie gave him another bulb before sticking her finger into his little butt and told him he had to wait to potty again.
Finally, she removed her finger tip and let Jimmy sit on the potty again.
While he was expelling, auntie emptied the sink and refilled it with plain warm water. Then, Jimmy was back on her lap getting a rinse enema.
She gave him four or five bulbs full while he giggled and she talked lovingly to him as she repeatedly inserted the nozzle in his rectum.
She sat him on the potty one last time and let him release till he was empty.
While she was waiting on Jimmy to finish, she talked to me, explaining the baby enemas, as she called them, made Jimmy feel better when he couldn't potty my himself.
She asked if my mother gave me enemas and I nodded that she did.
When Jimmy finished, she bathed him and we went back to playing.
Fast forward three or four years and I was out in a wooded area playing with Jimmy's sister, Mary, and female cousin, Patty.
Patty was aggressive and decided what games we should play and what the rules would be.
This day she announced that we would play doctor and that Mary had to take all her clothes off.
Of course, Patty was the doctor but I just stood nearby with my eyes wide open.
Patty pinched Mary's undeveloped nipples, pushed around her stomach before spreading her legs and stretching her labia apart while telling me to look. I could see pink folds of skin.
Then she made Mary get on her hands and knees and spread her cheeks to look at her pink anus.
Doctor Patty told Mary she was well and that it was my turn to play doctor while Patty was the patient.
Mary casually redressed as Patty quickly stripped off her play clothes, layed on the ground and told me to examine her.
I had never played doctor before, but I was curious and gladly knelt down, feeling Patty's undeveloped nipples and pushing on her stomach as I had watched her do to Mary.
When I turned my attention to Patty's hairless vulva, she bent her knees and spread her legs apart, inviting my inspection.
By now, Mary was dressed and knelt down to pull Patty's labia open to give me a good look at Patty's pink folds.
We didn't go any further because we didn't know anything more. Mary did pinch Patty's little vulva lips together a couple of times before her got on her knees and reached back to spread her cheeks so we could inspect her little punk butthole.
When Mary announced that Patty was well, she reached for her panties and play suit while telling me it was my turn.
By this time, I was very excited for reasons I didnt understand and my little penis was standing erect when I took my pants off.
The girls had me lay down and they took turns inspecting my penis and making me bend my legs and hold them up in the air as they looked at my anus.
It was all new to me but the girls' hands on my stiff penis felt good and I enjoyed looking at them naked.
That was our first doctor session and Patty made us promise not to tell anyone and we would do it again.
As I remember that summer, we tried to play doctor every time we were outside playing together if no parents were nearby.
Eventuly, Patty and Mary brought plastic swizzle sticks to our playtime and we took turns taking each other's rectal temperatures.
Patty had older sisters she had watched exchanging enemas and rubbing themselves.
Patty told Mary and me the accounts of what her older teenaged sisters did to each other and demonstrated how they rubbed themselves.
Of course, the older girls were masturbating to orgasm while taking their weekly enemas.
Eventually, they included Patty in the enema exchanges and she described the good feelings and how she enjoyed being included in the big girl games.
After that summer, I was hooked on playing doctor with little girls and hearing enema stories, which grew into a full blown fetish by my teen years.
