"Stop that!" Debby squealed, trying to push him away. "You can't do this to…"

Robbie wasn't to be denied. Immediately he moved his left hand up her belly and squeezed her huge tits through her blouse, roughly kneading the soft, spongy globes inside her bra. His right hand dove between her legs and massaged her cunt through her blue jeans.

As soon as she felt his hand on her pussy, Debby knew she was a goner. All day long she'd been dreaming of just this moment. Her muscles went slack; her curly haired cunt slit moistened and warmed to Robbie's touch. Suddenly it made very little difference to her that Steve was watching them, smiling.

"Ohhhh, Robbie, stop… unggghhh," she moaned. But her words held no meaning now, and both of them knew it. "Please, Robbie, don't… mmmnnn… anhhhh."

Robbie tore open her blue jeans and thrust his hand into her panties. Debby gasped as she felt his fingers invade the sopping pink lips of her cunt. Instantly, in spite of herself, she began to buck her ass, fucking her cunt eagerly on his hand.

"Ohhhh, Robbie!" she whimpered. "Ungh! So good… awww, unit unh, unh…"

"Take your pants off," Robbie demanded hoarsely. "I want to suck the juice out of your cunt!"

In the darkness beneath the overpass, with the cars roaring down the four lane highway, with Steve watching them, Debby obeyed as fast as she could. She kicked off her blue jeans, panties and tennis shoes, burning with the need to feel Robbie's mouth glued to her pussy. Then she turned and lay down on the beach towel in the sand, wriggling her ass, spreading her thighs as far apart as they'd go.

"All right, Robbie," she said shamefully. "But don't you tell anyone, Steve! You've got to promise."

"I promise," Steve replied sarcastically.

Robbie knelt on the towel between his teenage girlfriend's spread thighs. He cupped the cheeks of her ass in his palms and kneaded them greedily, rolling the milky flesh between his fingers.
