"Oh, it must be a hundred degrees out here, and my cunt is still warmer than the sunlight!" Sandy sighed aloud, her finger invading her twat. "I'm as wet as before!"

Sandy's gliding finger brushed her half-erect clitoris, sending a lightning-like shock through her thighs and swampy cunt-tube. The high-flying teenager moaned and stirred her finger in her seeping pussy socket as if she were mixing a batch of erotic martinis.

"Arghhhhhh! That feeeels soooo fiiiiine!" the little blonde wailed, her ass jerking up off the lounge's taut straps.

Sandy's other hand stole up onto her jutting nipples, her fingers caressing the aroused buds until the hand near her cunt was awash in pussy-oozings and the moaning teen was teetering near another climax. She drove her trim ass up into her thrusting fingers and mashed downward with her other hand until her pulsing breasts were forced flat against her heaving chest.

A long, thick shadow fell over the gyrating girl at that moment. Her blue eyes fluttered open and she looked up to see the towering figure of her uncle blocking out the sun.

"Uncle Jack!" she yelped in embarrassed surprise. "I, I…"

The stern, unforgiving look on her handsome uncle's face made Sandy stop explaining in mid-panic. She stared up at him in terror, her hands frozen to her cunt and tits.

Just when she was about to break into girlish sobs and plead for his understanding, something made Sandy look down from her uncle's stony face to his crotch. There was a bulge behind the zipper of his expensive slacks that looked as hard and unrelenting as his face!

How long had he been watching, Sandy asked herself? Did the mammoth hard-on under his pants mean more than the look of parental disapproval on his face?
