Okay, I was addicted to her. I won't deny it. This was, well, not just pleasure although God knows there was a lot of that, and not just a weird fetish although God knows there was a lot of that too. It was an odd combination of dominance and submission but that doesn't cover it either.
Her skin was clearing up because of the way I was taking care of her. After I washed her in our morning shower I would go over every square inch of her beautiful body and as I was doing that I was the one in charge.
She was utterly relaxed when I did that, almost like a cat asleep in the afternoon sun. And I loved tending to her. Each fold and roll, each deep tunnel, each blemish was precious to me and I enjoyed what I was doing.
I was especially careful around her pussy and ass. At her size, her mons was a bag of fat that hung, a separate thing, like a soft volleyball covered in skin with a simple slit down the middle. I would lift it, push the soft bag of her labia to the side and then carefully wash that fold. Given where it was, the bacteria from a couple of inches away, I often needed the Desitin. So I would wash and then dry and kiss and apply the white cream.
I had most of her body cleared up pretty well but that area between her thighs and her belly button, well, the deep crease that was her belly button, still often needed treatment. Robert Heinlein in a story once, I forget which one, had explained that God could not possibly have been an engineer because no engineer would put the sewer and the playground right next to each other. Mom was a good example of that poor engineering.
Oh, don't get me wrong. I kept her clean now. After her morning business when she would pee and poop I always washed her carefully. But it's a damp area, the kind of place that yeast and mold and bacteria just love. So I had to pay particular attention to those delightfully private places.
It turned out she enjoyed analingus. We discovered that, mutually, almost by accident. I was doing her back and had found the first hint of a rash on her taint - you know the old joke, what do you call that little spot between a woman's vagina and asshole? Her taint. "T'aint ass and t'aint pussy."
Anyway, I washed it, carefully but to do that I had to spread her wide. That little rosebud, tiny on her huge body, surrounded by that circle of perfectly smooth and hairless skin, beckoned and I kissed it. When her hips rocked in invitation I kissed it again, more thoroughly. When I smelled her arousal I used my fingertips to open her up. Mom's a big woman and she shits big so when I did that I had a good-sized tunnel right there. So I kissed it but also I ran my tongue as deep as I could.
And she came, suddenly and explosively.
It was so unexpected I just froze and watched as her natural lubricant, thick and white, kept flowing from her.
When she started to relax I ran my tongue up her ass again and she came again.
