The young girl shook her blonde tresses as if to clear the lascivious sight from her memory. She put her eye back to the hole and saw it wasn't a dream or a nightmare. It was happening.

It was really happening now, Lucinda soon discovered. Dawn's head was bobbing up and down frantically over Steve's hard prick. Lucinda could see her older sister's tongue pushing against the sides of her cheeks as Dawn's lips slid along Steve's cock-meat, her tongue swirling crazily as she sucked.

"Oooooooh, baby, stop it!" Steve suddenly moaned.

The boy's hands came up and forced the beautiful face to cease its obscene ride up and down his pulsing dong. He held Dawn's head in his hands and lay back sighing.

"No more, Sis, please. I… I really want to fuck you tonight. It's been a week since I shot in your pussy. I'll let you suck me off tomorrow night, I promise," Steve told his older sister in a hot, low whisper.

Dawn let her brother's rock-hard cock slip from her nursing lips with a loud pop. She grinned at him.

"Sure, honey," the long-haired blonde said with the same sense of urgency. "If you want to put this big, hot thing inside my little pussy, that's great with me!"

Lucinda thought her heart was going to stop beating. She couldn't believe what was happening in the bedroom, right before her eyes. Dawn couldn't actually be going to let Steve fuck her! Lucinda's mind recoiled with disgust at the very idea.

But Dawn's clearly did not. The voluptuous eighteen-year-old was moving up onto the bed, straddling her brother's reclining body and upraised dick. She put one hand on the base of Steve's cock and steadied it as she lowered her red, juicy cunt-lips onto his steely prick.

"Hot! Oh, Christ, you're a fuckin' volcano inside, like always," Steve murmured as her snug cunt slipped down onto his big cock.
