"Maybe you're being hasty," Bernice teased. "You haven't tried everything I have to offer."

Mike looked at her closely, then lowered his eyes to her tits. He then rolled away and placed his palm over her cum-splattered pussy.

"What's left?" he asked. "You have another pussy some place?"

"Well, sort of," Bernice said. She spread her legs and thrust her fingers between her thighs. "Ever made any rear deliveries?" she asked.

"You mean, fuck you in the ass?" Mike gasped.

"Sure," his mother said. "Ever tried it?"

"No," Mike said slowly. "I don't know any girls who'll let me."

"This girl will let you," Bernice said. "Mmmm, I'll let you do it all you want." She grasped his thick, throbbing shaft and jacked the loose foreskin over the oval head. "Mmmmmm, just so long as you do it with this big thing," she said.

"You're serious," Mike said, still wondering if she were. "I… you'll really let me do it?"

In answer, his mother rolled to her back and got to her knees. She looked at him over her shoulder and wiggled her ass suggestively.

"Ready when you are," she said, flashing him a wicked smile.

Mike looked at the rounded ass, his eyes taking in the gentle curves, the soft contours. He then swallowed hard as he crept behind her, planting his knees between her legs.

"Oh Jesus, this is going to be so good," he whispered, touching the tender flesh.

"Just go easy at first, Son," Bernice said. "That big cock might tear my asshole to pieces."

"That's what I want it to do," the boy said, now quivering with anticipation. He loaned forward and slipped his throbbing cock head into the delicate crack of her shitter. When flesh touched flesh, he gasped loudly. "God… so warm," he said, bending to kiss the back of her neck.

Bernice held her breath, waiting for the hard spasm of pain. Then, as the tip of his prick nudged into the puckered rim, she gave a loud, growling groan.
