My sweet very old mom

(this is all from when she was in her late 70s. I no longer think of my mother this way but I remember it happily)
My very old mom is short, and she has always been very skinny. Sometimes she seems almost just "skin and bones" as people say. But with still-lively, pretty eyes and full lips. And with tiny little saggy breasts, a slightly-furry vagina still, and -- right there in the middle of her now-flat and wrinkled old bottom -- a sensitive little anus. I know every inch!

A typical night a few years ago, when she was already quite old: Mom is in her nightdress after her bath, and I have my sweatpants on. Into the bedroom, and in moments, that nightgown is off again ("Oops, over your head, Mom!"), and I hold her bony little hips while she opens up a little and I begin eagerly licking her clit and labia, and I did not neglect to turn her around and lick her little asshole either, although she is still shocked the way I make sure my tongue goes deep into her little bottom. I lay her down and suck her tiny saggy little old titties -- I am moaning with pleasure and happiness as I do so, my dick throbbing in my sweatpants. I lap at her crotch until she is helpless and quivering with an orgasm, pressing her skinny legs together against my head and gasping.

After a moment of rest, I tell her, "I'm not finished with you, Mom." And I remove my pants and she sees now how hard I have been for her. Then she spreads her skinny old legs open, and I place the tip of my erect dick at the entrance of her vagina, nestling the throbbing tip against the wispy pubic hair that she still has. I lean down and while holding her face in my hands and looking into her eyes, I smile down at her and, in one strong deep thrust, penetrate her. "Oh," she gasps. "Oh, Michael!" And then, tenderly -- at first -- I begin to fuck her skinny old little body, methodically going on and on until I am fucking her as hard as she can take at her age.

Into her I go, deep in, and then out, in and out -- with each stroke taking ownership of that very same cunt I have such fine memories of seeing when I was young, when it was all covered with lovely dark hair. I lie on her, covering her with my body, clasping her tight and holding her as she receives my thrusting dick, and then I reach under her, down her bony back, and slip a wet finger all the way inside her little bottom and I hold her there too. I kiss her deeply. I have her everywhere. I own her. She is all mine now.

Then I feel her delicate old body quiver in my arms as she comes again, moaning and twitching. And then in turn I call out to her, "Oh, Mommy! Yes!" and I start to shoot my come into her vagina. I kiss her more, deeply, as my cum goes into her, my tongue in her mouth as I moan into her and my cum spurts deep into her... home again at last, home in my mother, my cunt, my fucked cunt mother.
