"It looks kinda small, Sharon," he said.

"It's supposed to fit," his sister replied. "It's supposed to go in me."

"Let's try," Jimmy grunted, his cock throbbing, his balls aching. "Let's try it, Sharon."

"Okay," she agreed, scooting higher on the bed, her legs spread as wide as she could get them.

Jimmy lay across his sister's naked body. He felt her tight tits burning at his chest. His cock slid between her thighs and across her cunt, throbbing at her golden pussy hair. Sharon wiggled, panting because it felt so goad.

"It's supposed to go in me, Jimmy," she whispered. "Not on top of me."

He lifted his hips, and she shoved an eager hand to his cock, pressing it downward. She gasped and her eyes flew open wide when his smooth cockhead slipped across her knotted clit.

"Ohhhh, that really felt good, Jimmy!"

She placed the head of his cock against the lips of her cunt.

"Push," she whimpered. "Push it in me!" Jimmy pushed.

"Oooooh!" Sharon wailed.

She wailed not because it hurt, but because there was a sudden twitching of her cunt and she started coming. Jimmy barely had the head of his cock inside her steamy cunt, and she was coming. Sharon had never come so fast when she fingered her pussy.

"Ohhhh, feel that, Jimmy?" she groaned. "Feel what's happening to me?"

"Yeah," her brother panted.

Sharon's sweet cunt lips were clutching the head of his cock wetly, squeezing as the orgasm ran its course. Her small body shook and Sharon choked with ecstasy.

The spasms began to fade, but her cunt was demanding, still.

Her pussy felt stretched more than her finger had ever stretched it, the sensations were fantastic. She wiggled her ass on the bed, arching her crotch up.
