It's one thing to catch your mother naked.
It's quite another to stand at the foot of her bed and watch her, face-down, as she reaches back with both hands, spreads her pale wide buttocks, and commands you to look at her asshole.
This, among many other things, was what I learned that day.
"Do you like Mama's tight anus, baby? Do you like to look at it?"
I didn't know what to say. I just stood there, wearing nothing but an astonished look, with the taste of her gushing pussy still strong on my lips and a young cock so worked up and solid that I feared it would burst under its own pulsing weight.
"No need to be shy now, baby," my mother purred over her shoulder. "Mama's shown you everything else on her body. Now she wants you to see her most private place."
I'd never looked at one in person. And even in my stash of dirty magazines, on the glossy centerfold pages where the girls always spread wide, I'd never given the ass much thought. But here, right in front of me, pulled wide open, it took on a whole new shine—literally, it was smeared with the messy juices of her just-gushing pussy, and stood out as slick and glistening as a pearl. It was much pinker than her pussy lips, and much more puckered, stretched tight on either side where her fingers pulled at it. The thinnest trail of black hair circled it before disappearing into the hot dark mess of her pubes against the sheets. It was a detail I didn't expect, and it struck me as an unusually filthy trait on a woman. Particularly when she was my own mother.
"Not so pushy now, are you?" she teased. It was true. I stood where I was, unsure what to do but too horny to step away. Her voice grew softer. "It's okay, baby. Mama just wants to make sure that you see it all. Go on," she half-whispered. "Step closer and take a good look at Mama's wide-open asshole."
I took a few steps.
"Come on, baby. It's okay. Mama wants you to get right up next to it." She brought herself up onto her knees and put her ass high in the air. She pulled tighter at her butt cheeks, exposing herself as wide as possible. Then she flexed her pussy, just like when she'd come earlier, and I watched her ass contract tight as a fist, then relax and open just a little. I felt a fresh batch of precum puddle at the end of my cock and spill out into a slow, sticky strand.
"Go on," she said. "Come over here and take a good, hard look."
I approached her and put my knees down on the mattress. A faint smell hit me, like soap and wet pussy and something much...deeper. It was strange, but it made my cock pulse even harder.
"Don't be shy. Get close and look at your Mama."
I sat on the edge of the bed and ran my eyes all over her—the flex of her back, the goosebump skin of her ass cheeks, the soft fatty tops of her thighs. And filthiest of all, the way she was posed—with her face down and her ass high in the air and wide open. My own mother, completely exposed.
"Do you like to see your mama this way?"
"Yes, Mama."
"You do? You like Mama all spread and dirty, with her most private places pulled wide open for you?"
"Yes, Mama." I could tell she liked talking about herself that way. Her butt started to make slow circles in the air.
"You see now what a filthy woman your mother really is, baby? Do you see how sticky Mama's thighs got from all that sucking and fingering. Do you see?"
"Yeah, Mama. I see."
"That's right, baby. Your mama's filthy. But you're going to help, aren't you? You're going to bend down and lick your mother clean."
"I am?"
"Oooh, yeah. Mama needs you to lick her ALL over."
I looked again at her tight pink anus, and then I understood. "Mama, you don't mean..."
She let out a wicked laugh. "You know EXACTLY what I mean, baby."
"But that's... dirty, isn't it?"
"You're goddamned right it is. That's why Mama needs you back there, to make sure she gets clean again."
"But Mama..."
"You said you'd do anything. Remember?"
Of course I did. But I never thought she meant...
"You want to be Mama's good boy, don't you baby?"
"Yes, Mama."
"Then stop making excuses and lick your Mama's asshole!" It was a tone of voice I'd known all my life, though under very different circumstances. It meant that Mama was done fucking around.
Slowly I put my face close to her ass crack. The smell hit me again, stronger, and I felt my own ass tighten against the pressure of my balls. Then, gently, I put my tongue out and ran it against my mother's spread anus.
