Wendy puckered her cheeks sharply, dramatically increasing the suctioning pressure around the fat shaft of cock meat. She shut her eyes, concentrating on the taste and feel of the big, juicy prick. Then she rapidly started fucking her face up and down on his huge cock, sucking the shiny-skinned prick knob as hard as she could.

"Oh, Jesus!" Bob gasped as he listened to the slurping, lip-smacking sounds of his hot niece giving him head. "No, Wendy, stop!" He made a feeble attempt to push her away. "This is incest! It's wrong, Wendy! No!"

Then his lust got the better of him. Wendy felt his hands relax on her head. A moment later they were sliding past her temples to grab into her long, thick black hair. Her uncle was now holding her head in position, groaning and sighing with pleasure as he watched her fucking his cock down her throat.

"Oh, fuck, I can't take it anymore," he gasped.

He pulled her hair and staffed to buck and grind his hips, jamming his ten-inch cock farther down her buttery gullet.

"Work out on it, Wendy! Oh, Jesus! Make it cum, Wendy! Make it cum!"

The spongy cock head was puffing outwards in her mouth, nearly choking the young girl. More creamy pre-cum was bubbling out of the hole in the tip. Wendy took his prickrod part way out of her mouth so she could lick up the jizz. Then she took a deep, panting breath through her flared no stills and rammed his cock as far down her throat as it would go.

She stopped with over half of his prick trunk clotting her mouth, when she knew she would have gagged if she'd tried to swallow another inch of his delicious prick. Wendy wrapped her right hand securely around the root of his cock and started jacking it as she sucked.

The combination of stroking and sucking always drove her father insane and she was sure she would do the same for Uncle Bob. Feverishly Wendy whipped her hand up and down his hotly throbbing prick, simultaneously sucking loudly and hungrily an the flared tip of his prick.
