It was too much for Joe.

Gasping, he ripped his zipper down. His prick sprang out like a rocket. He reached in and dragged his bloated balls out, then moved his hand away, letting his kid sister gaze at his naked cock.

"Oooooh!" Jennifer moaned.

Joe's cock-head was vibrating and humming. The dark vein pulsed up the underside of his cock, spreading out in the delta of his swollen cock-knob. His balls were enormous, holding promise of a most abundant cum load.

"Oh, Joe – you're so big and hard," she purred.

He pumped his prick muscles, making his towering cock jump and jolt.

With her eyes glued on her brother's prick, naughty little Jennifer began to squirm out of her bikini. She tugged it down and, raising one knee to kick it off, gave him a clear look at her smoldering cunt. Her pussy was open like a flower, all frothy with her spillage, her whole crotch lathered and her clit standing out like a bullet.

She removed her halter and her tits swung free. She stared in fascination at her brother's cock and he stared back at her creamy crotch, groaning. His cock was beating like a drum, and his sister's cunt was rippling and fluttering like a suction cup.

"Can I touch your cock, Joe?" she whimpered.

He nodded, dumbly, stunned.

Jennifer reached out and ran her fingertips up his cock-stalk and onto his sticky knob. She moaned, feeling him throb. Joe reached out and hesitated.

"Ummmm, touch me, too," she said.

Joe's hand, palm up, dipped into Jennifer's crotch. Her cunt spilled a creamy pool into his hand. He rubbed and squeezed, feeling her clit swell and her cunt-lips slowly unfold.

Standing there, face to face, brother and sister fondled each other.

Jennifer wrapped her hand around his cock-shaft and slowly pulled up and pushed down, making his cock-head flare. Joe's fingers traced through her wet cunt and pulled at her clit.
