She clawed at her brother's cock, squeezing it hard, thrilled by the way it throbbed in her fist. She wished he was naked, too, so she could play with his balls. But, although she wanted it badly, she couldn't say anything.

Robert squeezed the cheeks of his sister's creamy ass, his fingers digging into the flesh. Peggy spread her legs, urging him to touch and probe at her pulsating cunt. She could feel herself almost coming. Her clitoris was tingling like it never had before. She lifted her naked ass up, urging him to feel between her legs with the motion. But Robert kept playing with her ass cheeks. She felt his hand slip into her warm, inviting crack, brushing at her tiny, puckered asshole.

Her fist squeezed hard at his throbbing cock and she gave a soft squeal. Her fist jacked faster on his prick, pumping almost furiously now. Soft mewls kept coming from her open mouth as her eyes closed tight. Her body was shivering and burning.

She felt her brother's cock brush against her hip, leaving a wet trail on her flesh. She thought it was like a flame, scorching her.

Robert was spreading her legs farther apart, his breathing harsh. Her feet were over the lounge, and she knew he could now see her cunt. She wondered if he could see how hot it was, see her pussy twitching with the desperation to be fucked. Then Robert was on the lounge between her legs, and she knew he was going to fuck her.

"Robert, oh, we can't… we shouldn't…" But the soft throatiness of her words told him to fuck her, and fuck her now.

Peggy felt her brother's cock brushing at her cunt, and she lifted her creamy ass high in the air to make it easy for him. But he didn't stick his cock into her boiling pussy. Instead, she found it pressing upon the tightness of her asshole.

"No, Robert, not there!" she groaned. "That's the wrong place!"

But the pressure increased.
