"Play with my balls!" Bob gasped. "Oh, shit, Wendy, you're getting me close now! I'm gonna cum, honey! You're making me cum!"

Wendy sucked his prick as hard as she could, dragging her lips tightly up the bloated stalk of his cockmeat. Her wrist and forearm muscles ached as she slammed her closed fist up and down the tingling, pulsing shaft of his prick. Slowly she let her left hand drop between his legs, hornily clutching the huge, hairy, wrinkled sac containing his balls.

His nuts were just as big as they were obviously painfully congested with a big load of spunk. Delicately Wendy dug her fingers into his ball bag, making her uncle shudder as his cock head spurted a little drop of pre-cum onto her tongue.

Wendy kept sucking and stroking insatiably, fondling his nut sac as she happily fucked her face with his prick. Soon her uncle's prick was throbbing much harder and the cock-hungry teen knew she was about to get a bellyful of spunk.

"It's shooting, Wendy!" Bob groaned.

"Swallow it now, honey! Suck out my cum!" The hot, sticky cock juice fountained up from the reservoir in his balls, making all ten inches of prickmeat pulse wildly. Wendy mewled shamelessly around his spurting cock as she started swallowing the spunk, working her throat muscles and gulping rapidly. Spurt after spurt of Uncle Bob's cum splattered on the inside of her mouth and sprayed across her tongue.

"Oh, Uncle Bob!" Wendy took the still gushing cock out of her mouth to look adoringly up into his eyes, giggling as her pumping fist made the rest of his jizz squirt onto her cheeks. "You really popped your rocks for me good today, didn't you? That's some of the best tasting cum I've ever sucked in my life!"

Wendy thought of telling him that the very best-tasting cum still came out of her daddy's cock but decided against it. Her pussy was burning and she knew she had to get her big-pricked uncle to fuck her before his hard-on went down.
