"You're a very naughty boy, you know," Sally whispered. She had moved her hand down from his hair to his neck, which she was stroking gently.

He shifted slightly, moving his chest across her big tits, drawing his hands up along her hips and sides until they rested on the side swells of her tits.

Sally could hardly believe it, but this simple gesture was enough to ignite the spark of lust in her again. Her cunt contracted wildly, and a spasm of desire shook her clit.

She tried to keep her voice calm. "Billy, did you enjoy fucking me? Did I satisfy you?"

"Aw, Mom, it was the best!" Billy raised himself up on his elbows and gazed down at Sally. "I've been dreaming about fucking you for a long, long time!"

This only served to get Sally more turned on. "There's a lot more I could show you, Billy."

"Y-yeah?"

"Hm-mm. Like this, for instance." Gently, she eased him off of her, so that he was lying flat on his back. His prick, pale and limp, had shrunk to a very small size. The ball sac had become baggy and wrinkled.

Sally cupped the boy's prick in her hand, eyeing it lovingly. Then she leaned down close, her tits touching the bedspread, and she took an experimental lick from the little cock head down to the fuzzy cock hairs.

"Shit!" the boy gasped. His cock shuddered in Sally's hand, stiffening before her eyes.

She giggled softly, then licked down the length of his prick again. It swelled up even more, the cockahaft reaching its full, steely length, the knob bloating with blood. The rubbery skin blushed to a deep purplish shade that excited Sally.

Sally grabbed the boy's cock at the base and held it steady while she lashed the prick knob with her tongue.
