“Keith, darling. Do you think your mother is a slut?” Karen asked.

The boy grinned down at his middle-aged mom, his stiff prick half crammed up her big ass.

“Dunno, Mom. Do most sons get to fuck their mothers up the butt?”

“Noooooo ... No, Keith. And I guess most other mommies don’t suck off their son’s big boners, either. And I’ll even bet they would never allow their son’s to bathe with them, or even play naked together in bed!”

Keith snickered, then sunk another few inches of his Crisco-slathered prick into his mother’s itchy asshole.

“Some people are weird, Mom. Squirm your asscheeks a little more.”

Karen Thibedeau was 47 years old. She’d been a tantalizingly stacked and pretty brunette in her twenties and thirties. Now her hair had a touch of grey; and her big breasts hung heavier and lower on her chest. Her ass had widened to matronly proportions. All of this never failed to get her sixteen-year-old son’s cock rock hard. She took her kid’s erection as a compliment, and now felt a mother’s obligation to bring relief to his balls. It was a task she attended to several times a day.

“Ummm! Okay, Keith,” the aging mother on hands and knees groaned, bracing her mature body for a delicious assault. “Go ahead, son. Pump it in and out of Mommy’s butt really, really hard! Do it, son!”

His big balls slapping loudly against his mom’s upturned ass cheeks, Keith fucked her fast and hard, reaching under her soft body to lewdly grope Karen’s sagging boobs.

“Oh yeah! Your old ass feels great, Mom. Wiggle your buns some more ... yeah, like that! Can I slap your ass a couple of times for fun?”

“Oooo! That sounds wonderful, dear. Eeeee! And feels wonderful too! Oh God! I guess Mommy is a slut, Keith. A horny old fucking lady! Most mothers are cooking dinner for their sons right now — and here I am with your teenage cock inside me! Another mom might complain if her boy spilled his milk. But —ooooooo! Keith! — I let you spill your cum all over my face!”

“Yeah!” her boy pulled his shit-stained prick from Karen’s stretch-marked bottom. “Yeah, turn over, Mom! I wanna fuck ya between the tits and shoot my load on you!”

“Why, certainly, Keith! An older Mom must keep her teenager happy. And if a boy needs to squirt his cum all over his Mother’s face to be happy — oh, even if he needs to smear his creamy glop all over her lipstick mouth, making her eat it — why, then, Keith, this Mom is only too happy to indulge herself in such enlightened activities!”

“That’s good, Mom, ‘cause I’ve sure got a jumbo-sized load. And I can’t wait to splatter it all over you!”

The happy boy got on top of his loving mother, straddling her ribcage. He leered at the pale flesh of her drooping melons, playing with her goosebumped areole and plucked a single coarse hair from Karen’s left nipple.

“Oops! Thank you, darling. Older women sometimes get a hair or two growing on their breasts.

“It’s cool, Mom.”

He mauled her flesh for a while then slipped his throbbing meat between her sweaty cleavage and began fucking his mother’s spongy tits.

“Oh, Keith, sweetheart! This is sooooo obscene! And fun too, isn’t it?”

The shameless parent opened her mouth and hung her tongue out, ready for Keith’s cock syrup to spread across her face like she was a plate of flapjacks.

“Awww, Mom, you look so slutty like that. Can’t hold it! You’re making me cum! It’s gonna shoot! Ahhhhhhhh! Mommeeeeeee!!!”

Keith’s cock exploded all over Karen’s face, hair, and tits. Huge gobs stained the woman obscenely, making the mature mom look like a day-old glazed donut.

He laughed at her as he beat out the last few squirts and wiped the knob on his mom’s salt-and-pepper hair like it was his cum sponge, dizzy in his brain over what his own mother just let him do.

“You’re a slut, Mommy! Mommy’s a slut! A fuck-cunt old slut! Aw, Mommy! That felt so good, Mommy! I love your made-up face, Mommy, the way my cum drips down your chin onto your tits! Awwwww...!”

He collapsed onto his mother’s frosted flesh, his mouth seeking hers, his thick tongue sinking into it for a deep, tongue-slurping French kiss.

“Oh, Keith,” Karen sighed, lolling in a puddle of her son’s cum, “I’m so happy to have a beautiful young son like you ... Keith, Mommy wants to do something extra special with you now. Would you like to come into the bathroom with me, darling? I want you to see me pee. I’ll spread my legs so you can see it flowing right out of my body? Would you like that, son?”

“Oh, man, would I!”

The mother swung her cum-dripping ass sexily from side to side as she led her boy into the bathroom.

The night’s fun at the Thibodeau home was just beginning.
