Maria smiled shyly as she looked to the collar in her hands, her heart fluttering. Lexam would absolutely love this! The thought of her boyfriend sent a shiver down her spine, and she bit her lip anxiously, kneading the soft black leather in her hands.

Much as she wanted to wait to try on the collar when her fox of a boyfriend got home, she also couldn't help but feel a little curious as to how good it would feel to put on the studded band. The brunette wavered indecisively for a moment longer, before she slowly slipped the collar around her neck, clasping it tight.

She was rewarded with an immediate surge of a borderline erotic bliss, an exhilarating rush tingling along her nerves. It felt oddly natural to be collared like this; to be wearing the mark of a pet.

Maria wondered if Lexam would enjoy being her master... The thought of it sent erotic chills along her spine, and the brunette blushed; looking to the bed anxiously. She slowly made her way to the velvet sheets with a pounding heart, undoing her belt and letting her jeans slip around her ankles.

Would the fox like to see her posed on the bed like an animal? Like his animal? She let out a faint aroused whimper at the thought, slipping her shirt over her head and kicking off her pants. Her bra and panties fell to the floor next, soon forgotten as the nude girl clambered atop the bed, a lust-addled grin on her face.

Little did she know that her every thought; her every action was the collar hard at work. Indeed, Maria had no idea just how perfect the 'Perfect Pet Play Collar' she'd ordered was.

Just as it had swayed her mind, the leather collar was beginning to affect her body, lightening throat to a supple pink as it inspired her to try letting out a soft and enticing bark.

"A-arf!" She whimpered softly, blushing and imaging Lexam's reaction to the sound. No doubt his ears would perk; his tail would flick; and his cock... She drooled at the mental picture of her mate's throbbing red rod, her pussy clenching as it swelled, skin becoming a rosy latex.

"Arf!" Maria barked louder this time, slowly rocking her hips back and forth against an invisible force, imagining she was getting plowed by her furry friend. She moaned loudly with pleasure as she pretended the collar was making her change into his mate; into his perfect bitch.

As she did, her body changed more and more, hands and feet making the smooth transition into perfectly puffed paws; arms and legs taking on a far more canine appearance. Her voice was gaining a doggy lilt as well, her barks sounding less and less like a human's impression of an animal and more and more like the real deal.

God, it was perfect! The girl groaned loudly, a whimper passing from her gently puffing lips as her tongue slipped past them as well. The muscle was lengthening, growing thick and plush as it extended further, drooping well past her chin.

Maria panted openly, whimpering just like a bitch in heat as she tried to twitch her ears, pretending she was the dog-girl that Lexam so richly deserved. Much to her surprise, they actually moved, responding to her thoughts as though she had a canine set of ears on her head. Sure enough, in seconds she did; the collar changing her ears into a pair of perked canine triangles.

This was enough to break the young woman from her lusty stupor, and she crossed her eyes as her nose and mouth began to extend from the rest of her face, just like a canine's snout, if said snout happened to be a rubbery pink.

"Arf!" Maria yelped in surprise, only to echo her first bark with another as she realized she was incapable of human speech. Her arms and legs were oddly numb beneath herself, and she looked back to her butt in time to see a solid pink tail extend its way from her spine, the appendage lifting high like she was a dog flagging herself as in heat.

"W-woof?" The girl whimpered, beginning to panic. Much as she wanted to, she couldn't so much as move; couldn't reach her phone that remained stubbornly in the pockets of her discarded jeans.

Her tongue and mouth dried out as they became warm latex; and she moaned as her lips, pussy, and anus all tingled. All three of her holes swelled, becoming a rich red that matched the pink of her new form.

Though she wanted to call for help with all of her heart, it was already much too late for her. Now that the transformation had changed her body, it began to move onto her mind next, attacking thoughts that were human and transforming herself into something else altogether.

Maria could feel it too; could feel the encroaching tendrils of change slipping their way around her mind. It was a bizarrely arousing heat, which was driving her to moan and to rock back and forth once more, grinding against and invisible lover.

The collar sensed the weakness of her human lust and exploited it, making her pussy feel just like an invisible vulpine cock was plowing it. Maria's hole clenched around the invisible shaft as it took on a distinct o-shape, her latex folds dripping with a synthetic lubricant, and her heart began to succumb to the throes of pleasure.

"Unh, nhh, yip!" She moaned and grunted, drool pooling in her forever-open mouth, trailing down a tongue that was forever sculpted to hang lustily past her lips. Maria knew that she shouldn't enjoy this, but...

Another overwhelming wave of pleasure gushed over her form, warming the girl to her core. She quaked and whined just like a dog, yearning for more. It was so good to be used; to be a good doggy... No, a good dolly!

Her mind recoiled at the latest thought, Maria realizing that her thoughts were beginning to change to that of some sort of canine love doll's. And yet despite her best efforts, the walls she'd built around her personality, her memories were crumbling.

Already she couldn't remember her childhood, save a factory where she was molded into this form. She couldn't remember her years in school, now shortened to a series of invasive, albeit pleasurable, quality tests. She was even beginning to lose track of how she met Lexam...

Lexam. The thought of her vulpine boyfriend gave Maria something to hold onto, and she focused desperately on her happy memories with him, savoring the feeling of his fur against her nubile body. She needed him with every fiber of her being, just like a good doll should for their master.

It was a thought not entirely her own, but it was assimilated into her soul nonetheless. Just like that, she thought of her boyfriend as her owner, losing her romantic memories and gaining new intimate ones. He'd bought her and had used her well, his large shaft stretching her every hole; making her squeak and beg for more.

"Squeak!" the sound erupted from her frozen face, her vocal chords devolving further from those of a dog's to those of a love doll's. Oddly enough, some of her squeaks still approximated a canine's lusty whimpers; and they were music to her ears.

Maria squeaked louder and louder as she imagined Lexam pounding into her, feeling the last remaining vestiges of her mind; of her personality ebbing away. She was forgetting her name; forgetting her personality; her everything.

And in their stead, all that remained were a simple set of thoughts; thoughts of being used by her owner. Maria wasn't a person anymore; she was a dolly! And did she ever feel good about it! She existed only to be loved; to have each of her holes filled in turn; to squeak her pleasure loudly for her owner to hear!

Maria loved being a pink doggy dolly, with synthetic brown hair and such sensitive, round holes! She was endlessly horny, and she needed to be filled; to be loved; to be used!
