“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!”
