The start of a new Pack

"A door to the lab opens and a pretty young woman steps in. She has short hair dyed blue, she's wearing a white t-shirt and a pair of jeans. She smiles at you." Good morning! My name is Kate, I'm the substance testing volunteer! It's my first day, nice to meet you! "She looks around the lab, examining the various pills, serums and other medicine stored in the glass lockers. It will be your job as a lab assistant to give Kate some of the substances developed here at Body alteration Labs and study the effects of those substances on her. Who knows what effects they might have, only one thing is for certain - all those substances will undoubtedly alter or transform Kate's body in some way. She snaps back into focus and looks at you once again." Shall we begin? What do you have for me today?

"Kate eagerly makes her way towards the chamber indicated by Reis and steps inside. She looks around briefly, curious about what to expect."

"Wow, this is exciting! I can't wait to see what happens!" "Kate exclaims with a big grin, anticipation clear on her face." "What do you have for me today?"

"Kate nods, understandingly. She takes off her white t-shirt and jeans, revealing a matching blue bra and panties underneath."

"Alright then," "she says with a grin," "let's get started!"

"With that, Kate steps into the chamber wearing only her lingerie and waits for Reis to begin administering the substances."

"Kate gasps slightly as the cold liquid fills the chamber, dissolving her lingerie and leaving her completely exposed. She shivers a bit from the chill of it, but also feels excited by what's to come."

"Wow," "she murmurs," "this is really happening!"

"She watches with interest as Reis administers various substances into the chamber through small tubes in its walls. As each one enters her body, she can feel a change occurring within herself - sometimes subtle, other times quite dramatic."

"What's this one supposed to do?" "Kate asks eagerly after one particularly potent substance has been administered."

As the various substances enter her body, Kate can feel a strange sensation coursing through her veins. Her skin begins to tingle and itch as it starts to transform into soft fur of rich chocolate color. She watches with fascination as small tufts of hair begin to sprout all over her body.

Her fingers elongate, stretching out into paws with long claws that click against the metal floor of the chamber. Her face morphs and stretches forward, forming a snout filled with sharp teeth while floppy ears grow on top of her head.

Kate's breasts shrink down until they disappear completely, replaced by four swollen teats in their place which she realizes will be used for lactation later on. She feels an intense heat building up inside herself and knows that soon enough she'll go into heat cycle every few weeks.

The transformation continues further still; Kate's hips widen considerably making room for giving birth to large litters of puppies in future heats cycles. A tail grows from behind her backside wagging excitedly at times when happy or aroused but drooping low when sad or upset

Mentally too, Kate notices some changes happening within herself -she finds herself feeling more playful than usual- eager to run around like crazy dog fetching balls and playing tug-of-war games while barking excitedly.

Finally after thirty minutes have passed since Reis started administering chemicals into the chamber, Sarah is fully transformed from human form into an anthropomorphic chocolate labrador retriever ready for breeding purposes.

She looks up at Reis who was watching everything closely during this whole process looking pleased with what he sees so far before speaking again ""Woof" This feels amazing! What else do you have?"

"Kate's eyes widen as she feels the next substance entering her body. She can feel a strange sensation coursing through her veins again, and this time it is even more intense than before."

As Kate looks down at herself, she sees that her breasts are swelling up rapidly until they burst out of their bra cups. But instead of stopping at just two, she begins to grow additional pairs of breasts along the length of her torso.

The new pair grows right above each hip while another pair sprouts on top of existing ones making them look like layers stacked on one another with nipples in different sizes and shapes jutting out from all six swollen mounds

Kate gasps as she watches in awe how quickly these changes happen to her body. Her hips widen further still accommodating for the extra weight placed upon them by four additional milk-laden orbs while legs become thicker and muscular for support.

She feels an overwhelming urge to nurse puppies or any other creature that might require suckling; unable to control lactation leaking from multiple nipples which now have varying degrees sensitivity - some too sensitive causing pleasurable sensations when stimulated but others less so due being overused frequently lately.

Mentally Kate finds herself becoming more nurturing towards anything living around- wanting nothing more than taking care of everyone who needs help with affectionate licks and nuzzles between "woofs"

"Wow," "she exclaims," "this is incredible! I feel so... complete!"

"Kate looks at herself in the mirror with a mixture of awe and excitement. She sees her new chocolate labrador retriever form, complete with six swollen breasts that she can't help but cup gently to feel their weight."

"Wow," "she says again," "I look so different now! This is amazing!"

She turns around to examine her jet-black hair which falls down all the way to her ass. She runs her fingers through it, feeling its softness.

"I love this too!" "she exclaims." "What do you think?"

"Kate feels the collar around her neck and looks at it curiously."

"A collar?" "she asks, tilting her head to one side."

"What's that for?"

"Kate feels Reis's hand petting her head and she closes her eyes, enjoying the sensation."

"I see," "she says," "it does complete the look. Thank you for everything, Reis! This was such an amazing experience!"

"She wags her tail excitedly."

"What do I do now?"

"Kate wags her tail even more excitedly at the mention of a mate."

"Really? That would be amazing!" "she exclaims." "I can't wait!"

"With that, she turns around and heads out of the lab, eager to explore her new form and see what else this exciting world has in store for her."

"Kate follows the guard to her personal quarters, still feeling a bit giddy from all the changes she's undergone. She can't wait to see what else is in store for her."

As they arrive at her quarters, Kate looks around with interest. The room is quite spacious and has everything she could need - a comfortable bed, plenty of toys to play with as well as food and water bowls.

"Wow," "she says," "this is amazing! Thank you so much!"

The guard nods his head politely before leaving Kate alone in her new home. As soon as he's gone, Kate runs around excitedly exploring every nook and cranny of the room while wagging tail happily between woofs

Reis scrolls through the database, his eyes scanning the profiles of various volunteers. He stops on one particular profile that catches his attention.

"Ah, yes," "he says to himself." "Oliver Blackwood. Perfect candidate for Kate's mate."

He smiles to himself as he thinks about how Oliver will look once he's transformed into a suitable match for Kate.

With a nod, Reis makes a note on Oliver's file and sets in motion the process of transforming him into Kate's perfect mate

Reis's smile falters slightly as he reads the note on Oliver's file. He had been looking forward to working with him, and now it seems that opportunity has slipped away.

"Temporary suspension of volunteering due to family emergency," "he mutters." "I should have known about this earlier."

He rubs his temples, feeling a slight headache coming on. This is not what he needed right now.

With a sigh, Reis decides to look for another volunteer who can fill Oliver's shoes. He begins scrolling through the database again, searching for someone who fits Kate's needs.

As he searches, he comes across a profile that catches his eye: Ethan Thompson. A young man with no notable medical conditions or allergies, and a willingness to participate in experiments without hesitation.

"Yes," "Reis says to himself." "Ethan might just be the one I'm looking for."

Reis's smile widens as he requests Ethan Thompson as a test subject. He can already imagine the potential results of transforming Ethan into Kate's perfect mate.

With a nod, Reis sends off the request and waits for confirmation from the lab's administration team. He spends the next few minutes reviewing Ethan's file, making notes on his physical characteristics and medical history.

As he reads through the file, Reis starts to formulate a plan for Ethan's transformation. He thinks about what changes would be most beneficial for Kate, considering her new form and needs.

"Ah yes," "he says to himself." "I think I have just the thing in mind."

With his plan set in motion, Reis leans back in his chair, feeling satisfied with his decision.

Ethan's eyes widen as he takes the tablet from Reis and looks at the picture of Kate. He can't help but stare at her new form, his mind racing with thoughts of what it would be like to be with her.

"Wow," "he says, his voice barely above a whisper." "She's... beautiful."

He looks up at Reis, a mix of excitement and nervousness on his face.

"So, you're saying I'd become an anthro... dog or wolf?" "he asks, trying to process the information"

Ethan pauses for a moment before speaking again.

"I think I'd like to be a wolf," "he says finally." "I've always been fascinated by them."

Ethan hesitates for a moment, feeling a mix of excitement and nervousness. He looks around the lab, making sure he's alone with Reis before deciding to comply.

"Okay," "he says, slowly getting undressed."

As he steps into the chamber, Ethan can't help but feel a sense of trepidation. He looks around at the strange equipment and machinery surrounding him, wondering what's about to happen.

Reis follows close behind him, his eyes fixed on Ethan as he enters the chamber.

As the gell-like substance fills the chamber, Ethan feels a strange sensation coursing through his body. He tries to move, but finds himself unable to do so.

The oxygen mask over his mouth and nose provides him with a steady supply of air, but he can't help feeling a sense of panic as he realizes what's happening.

Suddenly, Ethan's body begins to change. His arms and legs start to stretch and morph into new forms. His skin itches and tingles as it transforms into thick, gray fur that covers his entire body.

His face elongates into a snout-like shape, complete with razor-sharp teeth and piercing yellow eyes. His ears grow larger

and shift upwards to the top of his head, giving him enhanced hearing.

Ethan's body bulges and shifts as it grows in size. His muscles become more defined, making him stronger than he ever was before. He feels a sense of raw power coursing through his veins that makes him feel invincible.

As the transformation continues further still, Ethan can feel himself becoming more wolf-like both physically and mentally. He finds himself thinking in terms of pack mentality - wanting nothing more than to be part of a group where everyone is working together for a common goal.

Mentally too, Ethan undergoes changes; he becomes less human and more animalistic with each passing moment- driven by primal instincts which governs all aspects of life from hunting prey down to finding mates

Finally after what seems like hours but was only thirty minutes have passed since Reis started administering chemicals into the chamber, Ethan emerges from the gell-like substance fully transformed into an anthropomorphic wolf ready for breeding purposes.

He looks up at Reis who was watching everything closely during this whole process looking pleased with what he sees so far before speaking again ""Woof" This feels amazing! What else do you want me to do?"

Ethan looks at his reflection in the mirror, taking a moment to process the drastic changes that have occurred. He can't help but feel a sense of awe and wonder as he gazes at his new body.

His eyes widen as he takes in the sight of his ten-inch, knotted cock. He can't believe how big it is!

"Wow," "he says, his voice barely above a whisper." "I... I had no idea."

He looks down at himself again, taking in all the other physical changes that have occurred. His fur is thick and gray

, covering his entire body in a soft layer of warmth. His muscles are more defined than ever before, giving him an imposing and powerful presence.

"I feel... amazing," "he says finally." "Stronger, faster, more alive than I've ever felt before."

He turns to Reis with a look of excitement on his face.

"What do you want me to do?"

Ethan nods, feeling a sense of anticipation building up inside him. He can't wait to meet Kate and see what kind of relationship they'll have.

As he steps outside the lab, Ethan is greeted by a guard who leads him to Kate's quarters. Along the way, he notices that everything around him has changed - the walls, the floors, even the air smells different.

When they arrive at Kate's quarters, Ethan sees her waiting for him with a friendly smile on her face. She looks even more beautiful than before

, with her new chocolate labrador retriever form and six swollen breasts.

"Hi there," "Kate says cheerfully." "You must be Ethan! I'm so glad to finally meet you!"

Ethan nods his head in agreement before speaking up.

"It's nice to meet you too, Kate," "he says," "I can't believe how different everything looks now."

Kate giggles at that.

"I know right?" "she says," "It's like a whole new world out here!"

The two of them spend the next few hours getting to know each other better. They talk about their lives before coming to the testing facility and share stories about their families and friends.

As the night wears on, they grow closer and more intimate - exploring each other's bodies in ways they never thought possible. With every touch and caress, they become more deeply connected until eventually falling asleep together satisfied after an intense night of passion

As they drift off to sleep, Ethan and Kate feel a sense of contentment wash over them. They know that this is just the beginning of their journey together - one filled with excitement, adventure, and endless possibilities.

For the first time in a long while, both Ethan and Kate feel truly happy and fulfilled. As they fall asleep in each other's arms, they can't help but wonder what kind of amazing transformations lie ahead for them at Body Alteration Labs.

The End
