"You may suck my cunt," she rasped.

Al knew better than to decline. Anyhow, he liked to eat pussy. He had often wished that he owed Crystal some rent, so that he could suck her pussy in payment. It had never dawned on him to go down on her when it was she who was in debt, however. It wouldn't have been fair.

He moved down the bed.

Hilda lifted her knees and tilted her cunt up like some hairy delicacy she was serving him. He paused for a moment, gazing down at her steaming cunt-slot.

Muff-diving on Hilda was like going down on the Colossus of Rhodes.

"Eat me, asshole!" she grunted. Al buried his head between the firm columns of her marble-white thighs and began to gobble her cunt. Hilda clamped her legs around his head in a scissor grip, blinding him, muffling his ears, gagging his mouth. He was sputtering as he sucked. The bald, shiny top of his head rested in her thick, autumn-hued cunt-bush and the rest of his head was buried.

"Suck, you cunt-lapper!" she hissed. Al sucked and licked dutifully. Her thighs parted, giving him some breathing room. But then she reached down and grabbed him by his saucer-like ears, tugging his face around in her foaming fuckhole.

"Drink my cunt-slime, fuck-face! Yeah – swallow the nasty stuff, you bald bastard!"

It would have delighted Crystal if she could have heard the way Al's sister addressed him, in these moments of raging sibling passion – and, maybe, made her understand why he was so churlish when she blew him, too.

Al munched steadily away and soon his sister's pussy was melting in his mouth.

He sucked her dry.

When she had had enough, she placed a foot against his shoulder and shoved him away.

Al had a hard-on again, inspired by his snack, but she wasn't interested in that. Fucking took too much energy, and cock-sucking was too indelicate for Hilda.
