Melanie's eyes narrowed. Her face became a mask of pure lust. Her head began to bob up and down on the dog's prick while her hand began to pump him faster, frigging his cock into her mouth. Her fist pushed down to the root of his prick, causing his cockhead to flare in her compressed lips. Then she drew her fist up, bumping against her mouth. Longing for his cum, she frigged faster and faster and sucked with gusto.

The terrier was becoming frantic.

Suddenly her mouth was full of dog-cum!

Great creamy ribbons of the sweet stuff looped over her tongue, skimmed inside her cheeks and poured down her gullet. Half crazed by her dark desires, Melanie swallowed as much dig-jizz as she could and sucked for more. The dog's balls held a lot more spunk than a man's. He spurted dose after dose of cum into her greedy maw and she drank it as fast as she could. But there was more than even the cum-hungry girl could manage. Jism overflowed her pursed lips and ran down her chin. Her fist flew up and down, milking the dog's cock and balls. Her lips pulled and her tongue fluttered under his cockhead and her throat worked as she gulped his cum-load down.

Finally, the dog's balls were emptied.

He lay panting and spent.

Melanie continued to frig and suck the animal's prick until she was certain that she had pumped out every succulent drop of his cum.

She pulled her lips away and used her tongue to gather up the errant drops of jism that had escaped her lips and run down his prick.

Then she sat back, looking at the dog, frowning slightly.

She told herself that she had only done it out of curiosity, and that now she knew what it was like to blow a dog and she would never do it again.

An hour later, she sucked the terrier off once more…
