"That's none of your business!" she snapped, trying to turn her face away.

He cupped her chin and looked at her. "I heard you thrashing around. I thought you might be having a nightmare." Then he laughed. "But you were fingerfucking instead. What were you thinking about, Peggy? This afternoon by the pool?"

Shame flooded her pretty face. "No!" she said, blushing furiously. "I wasn't! And I want you to go away!"

"So you can fingerfuck your hot pussy again?" he grinned. "I don't think you mean that, Peggy. I have something better than your finger."

He grabbed her hand and drew it to his lap. He was wearing shorts, and she trembled as her hand was placed on his cock. It was as hard as it had been this afternoon, and she could feel it throb beneath her palm. Automatically, almost unconsciously, her fingers wrapped about her brother's prick, squeezing it.

"Now, don't that feel better than your finger, Peggy?" he said. His voice was surprisingly soft, and she felt ecstasy building inside her. She gripped his cock very hard.

"Y-yes," she murmured. "Oh, Robert! I think I'm going out of my mind! I can't help it, either!"

"No, you aren't," he said softly, caressing her small tits through the flimsy gown. "You're just hot, Peggy. All girls – and boys, too – get hot. You're not the only girl to want a hard cock, you know."

All shame was gone as her passion bubbled. Peggy could not feel any shame now. It seemed that once she had her hand on a hard, throbbing cock, she didn't feel so guilty.

That came later. She sat up in bed, trying to shove his shorts away from his cock. Robert helped her, and then she closed her fingers around his prick tightly, pumping up and down. She gazed at his prick, saw the swollen head above her fingers.

"Take your shorts off, Robert," she said in a hot, quivering voice. "Take them off, please!"

"Only if you take your gown off, Peggy," he teased, running a fingertip over her small tits.
