Bobby didn't say anything when he felt his cock ready to spurt. He just grunted through tight lips, straining into his mother's cunt. The explosion of his come juice splashed along the walls of her pussy, sending Barbara into shudders of ecstasy. Time and again her cunt received the juices of his balls, and her orgasm increased until she was coming one spasm after the other. They seemed to come for a long time.

Bobby slumped, pressing his mother's knees against her tits. He pulled his hands free and slipped them under her lifted ass. He cupped his mother's ass cheeks, breathing hard.

"Piss in me," Barbara's voice came almost harshly. "Piss in my fucking cunt, Bobby!"

"I'll try, Mother."

He strained, managing to spurt a few drops of piss into her pussy.

"More!" Barbara urged. "Don't stop now! Piss in my fucking cunt, baby! Oooooh, I want you to piss in me… fill my pussy with hot piss!"

"I can't, Mother," he groaned. "I don't have to piss right now."

"Oh, damn!" Barbara replied. "Then let me loose. My legs hurt this way."

Bobby pulled his cock from his mother's cunt, and she lowered her legs. Come juice dripped from her pussy. "I'm sorry, Mother," he said.

Barbara looked at him, seeing the sad expression on his face. She sat upright, hugging him to her naked tits. "Don't be sorry," she soothed. "I just want to feel you pissing in my cunt. You'll do it later, won't you?"

"Mother," he said, awed. "I'll do anything you want me to do. Anything!"

"I know you will honey," she said, kissing his face, holding his cheeks with both hands. "I know you'll do anything I want."

She pushed him away. Seeing his cock dangling, wet with the juices of her cunt and his come juice, she dipped her hand and lifted it. Her face went down and her tongue snaked out. She licked along the soft cock-shaft, tasting her cunt and his come juice. She flicked her tongue over the head of his cock, taking up the juices there.
