Now she slid one fingertip up through her slimy cuntslot, then brought her hand up to her lips and licked at her own pussy nectar. The creamy stuff was delicious. She pushed her sticky finger into her mouth and sucked on it as if it were a prick.

"Ummm," she sighed, adoring the taste and the texture of that succulent cunt nectar. She scooped up another fingerful out of her pussy and lapped it from her hand. Catherine moaned and squirmed, really turning on to her self-stimulation.

She had forgotten all about the doggy.

But Rex had become very much aware of his mistress. As the sweet aroma of steaming cunt drifted across the room, the big black brute raised his blunt snout, sniffed and whimpered. His ebony nostrils flared. The doggy forgot all about his previous desire to chase juicy bunnies, inspired by the scent of even juicier pussy.

He turned his head, eyeing Catherine with wide, amber eyes. A quiver ran through his body. Rex growled softly. He had fucked a few bitches in his time, and the beast knew damned well what that fragrant aroma signified – a female in heat!

His massive prick began to harden and his big scumbags swelled under his loins. It was a perfectly natural response to that fragrant stimulation. After all, the Alsatian was only a dumb animal – how could he know that bestiality was wrong?

Still unaware of the dog's interest, Catherine began to run her hands up the insides of her wide spread thighs, teasing herself by not yet touching her pussy. Her ass twisted on the edge of the couch and her hips jerked in a fucking motion. She gazed down past her tits, staring at her steaming crotch. Even her human nostrils, so much more limited than the dog's, were aware of the musky, smoldering aroma of her aroused cunt. She tapped her fingertip against her clit and shuddered at the thrill of the contact. She was panting like a steam engine by this time and her cuntlips had spread out wide, so that her pussyslit had become an oval slot and that slot was full of fuckjuice. Her clit stood out from that creamy glen like a log in a swamp.
