Smug and satisfied, he took the girl home.

Her faithful dog was waiting.

That was the night when Melanie got her first dog-fuck.

The terrier was not tall enough to mount her dog-style.

Melanie sat on the edge of her bed and held the dog between her legs, his front paws straddling her hips. She fitted the head of his prick into her yearning, unfulfilled pussy.

The dog began to fuck with vigor.

The instant that she felt those vigorous fuck-strokes skimming into her cunt, Melanie wailed with the joy of it. It was so much better than fucking with a man. She thrashed about on the edge of the bed, arching her back and pumping her pelvis. Her ass churned and her hips rolled from side to side.

The terrier fucked rapidly. His sturdy body was like a buzz saw between her thighs.

Melanie felt the thrill run up her trembling legs and cascade across her heaving belly.

She was going to come! At long last she was going to come while she had her cunt full of cock! Her clit began to tingle.

The dog whimpered and slammed in and the crazed girl felt a hot load of doggy spunk rush into the depths of her cunt, flooding her pussy, filling her.

Her climax rippled and ran wild through her pussy.

The girl wondered why she had waited so long for such joy.

Once she had discovered the joy of dog-fucking, Melanie stopped going out with men very often and, when she did, she refused to go to bed with them. Her boyfriends were puzzled and wondered why she had suddenly turned from wanton to frigid.

But Melanie had not turned frigid at all. She was still promiscuous.

But now she was a promiscuous animal lover! It was only natural that she should wonder what a really big dog would be like. Her terrier had been wonderful and she still fucked him from time to time, more out of gratitude than anything else – and her duty as his mistress, of course – but he was too small. She began to look for opportunities to fuck the largest animals she could find.
