Catherine clamped her thighs around his shoulders, hooking her knees over his powerful body. Her leg muscles tightened and relaxed. Then she threw her legs wide open again, giving his busy head free rein as the dog slurped happily away.

Cuntjuice poured down her crotch. Rex's head ducked down, and he lapped the sweet stuff up out of the crack of her ass, then dipped into her fuckhole again. She jammed her loins down, fucking herself silly on his tongue. He was licking the inside walls and folds of her fuck slot, lapping the cuntjuice out of her from within. She could feel his tongue flare and expand inside her cunthole, then slide back out and run full length over her flaming clit.

The waves of ecstasy began to rush through her. As she neared the crest, the overflow from her pussy became hotter and thicker and even more delicious and aromatic, driving the hungry doggy mad. His tongue whipped into her slot, and Catherine jerked and squirmed under that steaming caress.

Her cunt began to melt. Catherine cried out joyfully as her orgasm peaked.

"I'm creaming!" she wailed. "My fucking cunt is creaming your tongue, Rex! Oh my God! I-I'm coming on a dog's tongue!" Spasms hit her, shaking her bones, turning her whole body into a quivering mass of orgasmic flesh.

The cum cream poured out of her in thick streams, and the cunt-hungry Alsatian slurped it up, yelping and whining at the feast. Catherine moaned and sank back along the couch, stunned. The dog continued to slap his tongue into her pussy, gathering up the last delicious drops and filling her fuckhole with his slobber.

"That's enough, boy," she panted.

For now, she thought – because Catherine knew damned well that now that she had discovered the joy of a dog's hot tongue, this wouldn't be the last time she fed Rex out of her creamy pussy.

She was already looking forward to getting lapped off again, as soon as she felt horny once more.
