"I'm just horny, Uncle Bill," Marie squealed. She squirmed close to the couch and started jacking on his cock, rhythmically pumping her fist up the hot throbbing prick shaft. "I'm just a horny little girl…"

Holding his cock in position, the wanton teenager lowered her head and pressed her lips to the bulbous crown of her uncle's cock. Bill shuddered and squirmed on the couch, wincing as his big prick quivered eagerly. More jism dribbled out of his prick head as she lasciviously licked up and down his hard-on, finally pressing her tongue an his cock tip to lap up his juicing cum.

"Unggghhh!" Bill's face gradually contorted with arousal. Marie felt his muscles relax as he succumbed to the pleasure of the licking. "Oh, Marie… honey… ahhhh!"

"It feels good, doesn't it, Uncle Bill?"

Pursing her lips on the crown of his hard-on, she kissed his cock adoringly. Then the horny little nymph opened her mouth wide, gurgling contentedly as she took the first several inches of his swollen cock down her throat.

Dazedly Bill locked at hey flushed face, seeing the way her full lips were stretched to bursting around his mammoth cock. "Oh fuck, Marie. I can't believe you're doing this to me. Suck it, suck hard!"

Marie pursed her lips around his boner, puckering her cheeks and mewling as she inhaled the cunt-wetting aroma of his prick meat. Hungrily she started to suck his prick, shutting her eyes tightly, thinking of nothing but the magnificent cock stuffed in her mouth.

Her nostrils flared. She made little panting sounds as she sucked, over the slurping smacking noises her lips and tongue made around his tool. Quickly Uncle Bill's cock grew longer and fatter in her mouth. Marie rolled her tongue all over the spongy head of his cock, darting it into his piss slit like a slippery sexual eel.

"Where… where did you learn to do that?" Bill gasped. "Oh fuck, I've never had my cock sucked like this before."
