Katy was happy for a short moment.
Everything that had happened to her and Sarah suddenly seemed to make sense. They were cursed to be creatures half human and half dog and her life as she had known it was on the brink of total change, but somehow she knew that everything would be fine when the group would reach Clara's grandmother. The old protector would explain everything and set things right. She'd give her and her sister a new view on life and on the things to come. She and Sarah would learn to live with the new doggy instincts and...
All they had to do was to outrun Cal and his tainted pack of dogs and the collar which gave them power.
Katy opened the car's door for her still transformed sister, so they could get back on the road again.
But, now that her mind was back on the subject, she slowly noticed that something had happened.
Clara was kneeling on the ground, her clothes lying beside her, where she must have had shed them in a hurry. She was furiously fingering her wet pussy and her facial expression was that of pure arousal. Short bursts of pleasureful whines escaped her half-opened mouth.
Sarah, still in her shepard-form, was again mounted by Buster.
All of them were fully enthralled in their lusty actions and none of them noticed the three dark shadows that were slowly moving out of the woods near the car. None of them but Katy.
"Found yaaa," Cal said in a gruff, nearly barking, voice.
Cal, Mark and Mark's mother Darleen left the woods no 20 feet from Katy. None of them was wearing any clothing, but somehow their skin looked like covered with a thin layer of fur. Their eyes gleamed in the moonlight.
Darleen, wearing the magical leather collar, stepped forward.
"It wasn't hard tracking you all. And it was a mistake of stopping here in no-mans-land, my dear. No one will help you when the power of the collar calls out for your cursed souls and finishes your transition as part of my pack."
Katy heard the words and slowly noticed that whatever power the collar radiated, was slowly affecting her, too. She was getting more and more aroused with every passing second and her boosted sense of smell was starting to inhale the near males' scents. She was getting into a bitches' heat and when she'd succumbed to it, she'd been lost to the collar's thrall. She had to resist!
"Clara, please!" Katy begged quietly, but her friend wasn't listening as her soul was already been reconfigured by the collar's halo of arousal. Fur started to creep over her naked kneeling body. Her ears grew pointed and sharp canines replaced her former human teeth.
Claras' transformation was at hand and when one of the tainted weredog males would mate with her, she'd be forever lost to Darleen's pack.
"There is no way of escaping, my dear. Soon you'll be a worthy addition to my pack. You'll succumb to your heat and then Cal will taint your body woth his seed," Darleen growled.
Cal stepped forward now, his once human penis being changed into a dog's sheath. His cock was fully grown out of it and glistened in the moonlight.
"Sweet sis', I'll make it as pleasurable as it gets... don't try to resist... when I've made you my bitch you'll never want to get it any other way..." Katy's brothers' voice was deep and alien to her, but somehow his words (and his incredible arousing scent) only heightened her lust.
While Clara was still changing while fingering herself madly and Sarah and Buster kept on humping away like in a trance, Cal closed in on Katy, his huge cock ready for action...
