Debby began to finger-fuck herself with both hands. Tilting her wrist, she slid the middle finger of one hand up into her fuck-hole while she pulled at her clit with the other. Her finger squished into her soaking, steaming slot. She added another finger, then began to shove four ran up her cunt, bunched together in a phallic bundle. Her cunt-lips sucked and pulled on her fingers, and her clit vibrated wildly.

"You ain't jerking off," she moaned, eyelashes fluttering, leaning closer to his cock.

Tommy gave his cock a stroke, grunting and jerking up from the bench. He had the blanket up really high now, and his sister's blonde head was under it, in the shadows, hovering over his prick.

"Oh, fuck! I'm so hot!" she whimpered.

Debby drew one hand out of her smoldering cunt and reached across, taking Tommy by the wrist and gently drawing his fist away from his thundering cock-shaft. She glanced up at hint through lowered lashes, speculatively. Then she folded her own hand around his cock.

Tommy jumped as if galvanized. His sister was holding his cock! It was wicked, but all the more thrilling because of it! He knew that he should stop her, but he couldn't. He was over whelmed by lust, and her hand held him by his prick. She pumped up and down, and worked her thumb against the underside of his cock-head.

"Touch me, too," she pleaded. "Put your hand on my cunt, Tommy! Make my pussy cream!"

He reached across and dipped his hand into her pussy. Her fuck-slot was scalding hot. He slid two fingers up into her cunt-slot and wriggled them around inside her, while his thumb whipped back and forth against her vibrant clit.

"Oooooh! That's so nice!" she sighed, wriggling her hips and jerking her ass in a fucking motion.

The waves of bliss had already started to ripple across her belly and to shot like electric currents up her trembling thighs. Wanting them to cum together, she began to beat his cock faster, her fist skimming furiously up and down.
