She started to twist and turn as she fucked. Her cunt pulled and sucked. She watched his face change with each new variation. She gripped the towel rack tighter. Her ass launched into a rapid grinding. She gauged her breathing and poured all her strength into sliding her daddy's big, wonderful cock in and out of her flaming cunt as fast as she could.

She watched her body bounce and wiggle. Her tits were jiggling. The pink nipples were hard and round, and they tingled in a surprising way. Her lean legs were splayed and flexing, exposing the strong muscles in her thighs. She added more fuel to the fire, humping and fucking until it seemed like she had always been there, always riding up and down on her father's cock.

Her pussy was hot, wet, and gripping tightly at her daddy's prick. It felt like a tight glove of flesh shaped exactly to every bulging vein and steely curve of his cock. Her cunt flowed and moved with the fast pistoning she relentlessly kept up. And it seemed to glow. The glow sent sparks that traveled up her spine.

The sparks set fire to her brain. She panted her breath between her clenched teeth and slammed her pussy down until her vision blurred. She felt the whole monstrous length of her father's cock fuck up into her with every hammering stroke. Then more sparks. More fire. And she fucked even faster.

To believe that anything could be as hard and hot as her daddy's huge thick cock was tough enough. But to believe that her little pussy could manage to wrap around all that cockmeat and swallow it all, over and over, was almost impossible.

Then his hands were slowing down. She looked at him. He was straining, his face red. He was jerking spasmodically, his hips twisting his throbbing cock in her bouncing body.

"What's wrong?" she asked, glancing at the door. She hadn't heard a knock.

He slowed and stopped her. Her pussy gripped tight, halfway down his prickshaft. His balls were drawn up tight. His cock was throbbing with the fast beat of his heart.
