"Fuck me, Billy," she whispered. "Fuck me!"

"See there," Billy said. "I told you that you'd beg for it before the night was over."

Billy was proud of himself as he climbed on top of her. He separated her legs even wider and placed his cock just at the entrance to her cunt.

"Get ready, baby," he said.

He gave a savage push and his cock tore into her, filling her up.

"Oh Billy," Marilyn moaned. "Oh Billy."

Billy started to fuck her in rapid, hard strokes that drove his hard cock deep into her cunt. He was breathing heavily and his balls slapped loudly against her.

"That's it, boy," the old man said. "She's feeling it now. Fuck her good, boy. Fill up her cunt. Fuck her hard. That's the way they love it!"

She tried to close her ears to the old man's voice but she kept hearing him urging Billy on, as if he was in a race or something.

Then she didn't care anymore, for she felt the first tingle of her orgasm approaching. She started slamming herself up to meet Billy's stroke.

"Billy," she cried. "You're making me hot! So hot! I think lm going to come, Billy! Oh Billy, I am coming! I ammmmmmm!"

Billy grunted loudly as he gave her one last stroke and then his prick exploded inside her. He sent large wads of jism into her cunt that made him cry out in joyous delight. She kept grinding herself against him until he'd finished trembling.

He withdrew his now limp prick from her cunt.

"Goddamn," Billy said. "You're as good a fuck as Timmy said you'd be."

Marilyn was in a daze. Her climax had been so good. It seemed like she was hearing him from far away. She was hardly aware of when he left the bed and Danny replaced him.
