I got a few chances to witness my sis getting an enema. It usually happened late at night when most were sleeping. I could tell when she was about to get one because our stepmom had a habit of dosing us kids with a strong, foul tasting laxative.
My sis would protest the proposed medicine until stepmom issued the ultimatum
"A laxative or an enema, what's it going to be?"
This usually produced the desired effect as us kids would usually gag down the terrible liquid. Ironically, despite having had the laxative, an enema was often added for my sis, less often for me.
I had heard the muffled protests late one night coming from the bathroom. I crept to the deck to get a good view and was rewarded with an extended show as I witnessed the poor girl being subjected to the "Three Bags Full" routine that was favored by step mom but hadn't been forced on me...Yet.
I was caught by my sister when she noticed me peeking. I was threatened with an enema myself and was both expecting and looking forward to it. It had been a long time since I'd been given an enema.
When it wasn't forthcoming after an hour or so I asked sis what was happening. She said mom changed her mind and wasn't going to do that.
I was disappointed and began to tease my sister about having to have so many enemas. I began to call her Squirt and that did it. A little whining and complaining brought mom to our room where I was threatened again. I probably could have avoided it. Not only did I not want to, but the thought of mom & the girls (our cousin Hillary) all watching me, turned me on.
I kept teasing then finally baited my stepmom by saying,
"I knew you wouldn't give me an enema, even if you did, it's no big deal."
That opened the floodgates so to speak and I soon found myself nude, lying on an old towel on the bathroom floor eagerly waiting for my parent to return with the pan of warm soapy water that would soon find its way into my eager bottom.
Instead of the old pan, My eyes widened as three half gallon pitchers filled to the brim were brought in by the snickering girls.
I asked who all that was for figuring perhaps the girls might be getting more
I gulped and shivered when I was told that since it was 'no big deal', I wouldn't mind a "good clean out" and the customary 2 or 3 cups I usually received on the rare occasions when I got it, would be increased to 3 FULL BAGS.
Though it was very difficult, embarrassing, and uncomfortable, the girls managed to get all three bags into my quivering, protesting, young bottom.
It was a long time after that before I took any other enemas. However, within the year, I was back at it on my own.
