She giggled at that thought, thinking: the dog sure as hell isn't going to tell anyone?

Unable to resist the impulse, Melanie pushed her tongue out and licked the moist tip of the terrier's prick.

It was delicious.

She licked his cock again.

Dog-spunk bubbled onto her tongue, causing her taste buds to tingle, driving her wild with lust.

She began to lave the dog's cockhead with long, slurping strokes, curling her hot tongue all over the meaty nugget while her hand continued to pump his cock. She felt very depraved. Even alone with the animal, she was blushing furiously, ashamed of what she was doing. Yet she couldn't seem to stop. She just kept tonguing away. Once or twice she drew back, telling herself that it was time to stop – but then she ducked right back down and licked his prick some more.

His pre-cum was flowing freely by this time, and Melanie was lapping up plenty of the delectable cock juice and, like an appetizer, those first tastes were increasing her appetite.

She figured that maybe she ought to blow the dog, after all.

She reasoned that since she had aleady tongued his cockhead, it couldn't be any more wicked to take his fucker into her mouth. The prospect caused her to shiver and tremble all over. The terrier was whining and whimpering and humping his ass, evidently thrilled at getting his first tonguing. His horniness made her desire his cock all the more.

Melanie fitted her lips to the tip of his prick.

Then she let her lips part as she slowly fed the dog's cockhead into her hungry mouth.

She sucked on his cock-knob, her cheeks hollowing in and her lips pulling on the hot prickmeat.

My God! What am I doing? she asked herself. I'm sucking a dog's cock!

She felt dirty – deliciously dirty! The fact that she thought it was wrong to blow a dog only made it more thrilling. It made the girl yearn for his jism. His cock was hotter than the man's she had sucked, and harder, too, and the dog was starting to yelp with joy.
