"Hey, I didn't hear from you today," Kim said as she closed the front door of their home to find Lili waiting for her on the couch. "Busy day?"
"I was sent home early," Lili told her. She sat cross-legged on the couch in her skirt with her hands covering the collar. Her thumbs endlessly played with the buckle, caressing the smooth surface, flicking the prong and then pressing it back down and then rubbing the outline of the buckle once more. After a while, she shifted her thumb over to the control loop to run her thumb back and forth over the arched metal surface. It helped to soothe her.
Her stomach still hurt occasionally, but so did her testicles. Every few minutes, a pinching ache would form and quickly vanish in one or both of them.
"Aww, babe, you alright?" Kim asked. She set her purse down and hung her coat. After stepping out of her shoes, she walked to the couch to sit beside her girlfriend in order to give her a hug.
"Oh. Yeah. Yes, I'm fine," Lili said. Her eyes flicked to her girlfriend and then the collar.
"What happened?" Kim asked.
Lili slid toward the end of the couch so she could turn to face her girlfriend. She looked up at her briefly while her fingers continued to toy with the prong on the collar's buckle. "Do you believe in magic, Kim?"
"No?" Kim answered while tilting her head in confusion. "What's this about, Lilith?"
"Ahhh, my full name," Lili sighed. She flicked the prong faster. "Do you, um, do you want to believe in magic?"
"I love you, Bug, but you really need to be a bit more clear right now. I'm a little worried. Did you get fired?" Kim asked. "It's okay if you did. You can tell me."
Lili finally lifted the collar in her hand and Kim's eyes immediately went to it. "This collar turns me into a dog."
Kim searched her girlfriend's face, trying to intuit the meaning behind Lili's words.
"I don't understand," Kim finally admitted.
"Oh, no, I'm being literal," Lili told her. "Literally. When I put this collar on, I literally, physically begin turning into a dog."
"Lili..." Kim sighed. "Is this- I'm not sure how I feel about this. What are we doing here?"
"You don't believe me," Lili said after a moment of consideration. "You- oh, you think this is a fetish thing, don't you. Like, um, pet play? Kim, no, I'm being serious. Physical changes. And mental changes. If I put this on, I start to literally turn into a dog. I can prove it."
"By putting it on and showing me," Kim said with a clear note of doubt in her voice.
"Yes," Lili said sincerely.
Kim frowned with her brow creased. She knew her girlfriend - knew her girlfriend's behaviors.
"You really think you will, don't you," Kim said.
Lili licked her lips and looked back down at the collar. "Listen. When- when I put it on, my thoughts go all fuzzy. I'm going to need you to help guide me. If- if it starts to go too far, I want you to take it off. I don't know if it will become permanent if it goes to completion."
"Lili-"
"Promise me?" Lili asked. She rubbed at her lower stomach and then reached her fingers down to lightly touch herself when the strange ache reared its head. "As nice as it felt, I don't want to be stuck as a dog forever. I think."
"Okay," Kim said but her lip trembled. She gripped her hands tightly together as she began to think of the calls she might have to make. Or the arguments they may have with the need to schedule therapy for whatever her girlfriend was currently going through.
Lili took a deep breath before exhaling slowly. "Oh. Better if I'm naked, maybe."
True to her word, she stripped herself, carefully folding her clothes in a pile she left on the arm of the couch. Kim continued to watch with a face that did nothing to hide her fears.
"Okay," Lili said while holding the collar in front of her neck. She took another deep breath and then let it out. "Remember. Not all the way."
"Yup," Kim said.
Lili bowed her head and tilted it to let her hair fall to the side to expose her neck. A thick spray of black fur covered her nape, down nearly between her shoulder blades. A few hairs stood out on the back of her shoulders. Kim sat up and leaned forward when she spied the hairs, but Lili wrapped the collar around her neck, partially hiding the fur from view. With the buckle in front, she slipped the strap through the frame and under the loop until it was comfortably tight. The prong slid until it found a punch hole.
"Okay, it- nnngh," Lili groaned when the pain returned immediately to her stomach. She leaned forward and her hair fell around her face.
"Lili? What am I looking at here?" Kim asked. "Are you okay?"
The spreading sensation returned to her belly, but it combined with the pinching pain focused within her testicles. She growled and Kim's eyebrow shot up.
"Babe, nothing's- oh shit!" Kim yelled when Lili looked up to show short fangs bulging from her mouth. "Oh shit, Lili! Shit!"
"It's- it's okay," Lili said. Her tongue slipped out, already long enough to brush her nostrils as the skin bubbled out into a gray, pebbled texture that darkened further to coal black. "Just. Some pain. In my- nngh."
Lili turned. She brought her knees forward before bending to press her stomach into her thighs while burying her face into the arm of the couch. She shivered as cramps clenched little claws deep inside of her stomach. The couch muffled her growls.
"Fur! Lili! I can see it on your back, holy fuck you weren't joking, Lili!" Kim shouted. "I'm going to take the collar off!"
"Not. Yet," Lili said with her face turned briefly away from the couch.
The fur covering Lili's neck and upper back spread slowly, individual hairs piercing her skin within the mass of existing fur as well as along the edges, black hairs mixed with tan and a few gray ones.
"Oh my god. Ohhhh my god oh my god," Kim said. Her eyes widened when she watched the skin swell just above the crack of Lili's bare ass. "Is that- Lili is that- oh shit it moved!"
Lili whimpered. The warmth from before had become a heat that left her shivering and sweating. She whined and turned to stare at her girlfriend with bronze irises surrounded by a thick black ring and barely any sclera. Coal black streaks touched her lips as they became puffy and the skin raised in the middle of her top lip as the coloring spread up to her philtrum.
"Happening. Faster," Lili panted. "Every time I put it on. Happening faster. I- ggrk!"
Things moved inside of her. She could nearly visualize it happening as tissues formed and organs developed. It felt as if someone had their hand inside of her, spreading her open as it shoved into her crotch with fingers pushing and shoving and pulling - slippery movements that made her squirm.
Bones cracked, shifting Lili's hips while her legs rotated slightly. She sat back, whined, licked her lips and nose and then bent, folding as she reached her long tongue out to her crotch to lick herself.
"Uh, Lili, what, uh, what are you doing? Is that-? Lili! Lili look!" Kim called out.
Despite her girlfriend's urgent words, Lili focused on licking. There was a peculiar itch spreading throughout her crotch. Her penis bounced, hard but small as skin gathered around the shaft. It retreated into the flesh while angling down as if pulled, moving until it was properly between her lightly furred thighs.
Ebony streaks showed in the stretch marks on the swelling flesh surrounding the receding cock.
A shape began to take form as the skin bulged. The tip of her penis vanished within before splitting to show slick, pink muscles. Above her new vaginal canal, her jet black spade finished folding. Her tongue wrapped around the distended, jutting expanse of skin that hid her clit.
Kim's lips parted as she focused on her girlfriend's dog-like pussy. She moaned and pushed at her own clit while breathing in the musk surrounding her. A small part of her knew she should be disturbed at the sight of it, along with the way her girlfriend was changing, but the larger part of her felt a deep ache that spread out from her crotch towards her stomach.
She grinded her teeth while wrapping her thumb and index finger around the base of her hood and clit through her pants. The rest of her fingers rested lightly over her pussy. She squeezed her clit and pulled as it swelled further out of the hood, half an inch long with a tiny vein on the side of the smooth pink flesh.
Lili froze mid-lick and looked up. Bones moved beneath her face as holes opened above her lip to emit black whiskers. Her long ears rotated and her nostrils widened as slits formed at the edges. When the bones shoved forward, her nose was dragged with it, widening until the nostrils faced forward. Her nasolabial folds pushed outward to show the hints of a muzzle while gaps appeared in her gums.
The dog girl placed her hands on the couch. Her dangling thumbs with their curved, long black claws caught briefly in the fabric on the cushion as she took a hesitant "step" towards her girlfriend. The rotated bones in her hips forced her to all fours like a proper bitch. At first, her legs were dragged awkwardly behind her until pieces of the bones dissolved to shorten them.
Kim's chest rose and fell quickly as she continued to stroke her clit, which now bulged against her pants. She stared at her girlfriend's changed face before glancing along her back to her ass and the furred bulge of her tail as it lengthened and waved behind her.
When... when is too much? Kim asked herself as she suddenly remembered her girlfriend's request for when to take the collar off.
"Lili?" Kim asked with a low, hungry voice. "Are- are you still there?"
"Yeash," Lili answered, the words strange in her elongated face. Gray and black and brown hairs emerged slowly over her cheeks and the front of her muzzle. "Herrrr."
The girl lowered her head with a growl and shoved it against Kim's crotch. Kim leaned back with a gasp while reaching out to grab Lili's head. Lili's tongue was thick with her slobber and it immediately soaked into the thin fabric of Kim's work pants before touching the panties beneath.
"Oh, fuck!" Kim gasped. Her fingers tightened in her girlfriend's hair and she pulled, shoving the dog girl's broad nose into her clit.
"Here," Kim panted. She let Lili's head go to unzip herself and her inch long clit popped free. Three little veins stood out on the side of it and the tip showed a slight curve.
Kim screamed and grabbed Lili's head with both hands when the other woman's rough tongue pressed against her swollen clit.
"Oh fuck oh fuck oh fuck, Lili!" Kim screamed while raising her hips as if humping her growing clit against her girlfriend's tongue. She reached her left hand down to Lili's shoulder to claw at the fur and skin she found there while her right moved to clench Lili's long, furry ear. "Suck it! Suck on it! S- aaaaahhhhHHHN!"
Kim bucked as she came and her pussy muscles pulsed, leaking clear liquid into her pants and panties while Lili aggressively continued to lick her girlfriend's clit. When Kim tried to push her away, Lili growled and raised her paws up to Kim's hips to grab tight.
"It's too much! Lili, it's too much!" Kim shouted as a smaller orgasm rippled through her. She shoved, pushing against Lili's muzzle until the other girl finally sat back with a sad whine. A string of drool hung from the tip of her tongue. With her head filled by Lili's musk and the strange arousal brought on by the growth of her clit, she stared at Lili with hungry eyes. "My- my turn. Lay back. I'll take care of you."
Instead of doing as she was told, Lili turned and lowered herself while raising her ass with her tail curled above her.
Mirroring her tongue, a clear string of liquid hung briefly from the tip of Lili's spade before her trembling body caused it to swing and attach to the dense fur on her thick thighs. Lili turned her head to stare back at her girlfriend. Her face was an odd mixture of human and dog, half furred with a broad, black tipped nose.
"Are you still there?" Kim asked.
Lili growled and then nodded slightly while shoving her ass back, bringing Kim's focus back to her pussy.
"Been a while," Kim said quietly as she leaned forward. Her hand slipped back to her clit, two inches long now and she stroked herself with one hand while leaning forward on her knees to kiss her girlfriend's pussy. It was warm and wet and the lips had a spongy texture as they compressed against her mouth. She hadn't tasted pussy in years. Her free hand clenched against the fur growing over Lili's ass as she worked her tongue.
Lili shuddered and whined as Kim sucked the tip of Lili's pussy into her mouth. Kim closed her eyes and she grunted as she sucked her girlfriend while pulling the furred skin of her hood up and down her clit. She lost herself in it, opening her mouth wide to take the entire spade in her mouth while shoving her tongue deep
It was unlike anything she'd had before and even the taste was unique. It... did something to her. Kim grinded her teeth hard enough that her jaw flared when she leaned back for a moment. Tension built in her core and back and it tightened. Aggression welled within her as she listened to Lili moaning and whining like a bitch in heat.
Kim pulled back once more and wiped her mouth. Her red clit bulged from the sheath surrounding the base and she groaned loudly as she squeezed and pulled at it. Lili whined loudly. The dog girl could feel a strange pressure inside of her along with an emptiness that begged to be filled - begged to be itched and touched.
"Gonna. Gonna fuck you," Kim said roughly.
The young woman stood with her left hand on the back of the couch. She stepped to her girlfriend and leaned over her until her shirt pressed into the fur on Lili's back. Kim bit at Lili's ear as she adjusted herself, hunching her hips until she felt her clit pressing against her girlfriend's spade.
"You like that?" Kim asked as she reached back, gripping her four inch long cock to press it in the center of Lili's drooling spade. "You like-"
Her mind swirled, lost to the aggression humming throughout her body. Lost to the thought of her girlfriend as a dog. The feel of fur against her body was intoxicating. She moved her hands from the arm of the couch down to her girlfriend's side, as if clawing at her.
"You like being mounted like a bitch?" she continued as she thrust her cock into her girlfriend. It was small, but Kim's eyes shot open when it shoved inside and. The feeling was unreal. The nerves lining the red, pointed little dick lit up as Lili's virgin pussy muscles clenched hard against her.
The spoken words were true, she realized. She was mounting her girlfriend. Mounting her bitch. She thrust as deep as she could and even her small size still caused pain for Lili - pain that Lili ignored as her heat screamed at her.
"Brrrrrreed!" Lili snarled.
"Yeah? Yeah, you want that?" Kim asked as she began pounding. Lili's spade flattened against her, warm and soft and wet. "You want me to breed you? Want me to fill your belly with- with- with puppies?"
Lili howled as she orgasmed from her pussy for the first time in her life. She raised her half-muzzle, still only partially covered in fur, and her ears bent backwards as her black, fleshy lips formed an "O". Her claws tore at the couch while her legs kicked and she dropped to the cushions.
"Breed you like a bitch," Kim grunted, still pounding into her girlfriend. Her own orgasm was close and her eyes were staring, unfocused and wild. "Fill you up with them. Puppies. Until- OH FUCK! FUCK!"
Kim's pussy clenched. Her hips shuddered and she bucked while pushing her little cock deep into her girlfriend's spade - driven by a new instinct. She wrapped her arms around Lili's stomach as the intense orgasm sent spikes of lightning throughout her body.
Eventually, she pulled out and slid to the side, gasping and shaking.
"Are- are you still there?" Kim asked.
Lili twitched but didn't answer. With the remaining amount of strength she had, Kim reached out to undo the buckle on the collar surrounding Lili's neck. She pulled the loose strap and the collar fell to the couch. Lili sighed and rolled until she was facing her girlfriend. She licked the sweat from Kim's face and then groaned as some hairs were pulled back into her cheeks while others simply fell away.
The crackling of bones was faintly audible and Lili whimpered softly as the changes slowly, slowly reverted.
Almost half an hour later, the two women stared at each other on the couch.
"You okay?" Kim asked. She reached out to stroke her girlfriend's cheek gently.
"Yeah," Lili answered. Her voice was rough. "Did I really have- I remember most of it, but it's a little fuzzy here and there. Did I really have a pussy?"
"Yes you did," Kim said. She felt a blush touch her cheek as she replayed what she'd done. The words she'd said. It felt natural at the time. But, now...
Kim blinked rapidly. It still felt right in her mind.
That's- that's weird, she thought to herself. The memory of it sent a thrill of arousal running through her body. It didn't just feel right - it felt hot. The idea of mounting Lili and breeding her made her shift and gasp quietly.
Something moved low on Kim's stomach. She yelped and sat up and then screamed as she stared down at the bulbous sheath swaying in the midst of her curly golden-orange pubic hair. The pointed red tip of a small cock was half exposed from the slit on the tip of the furry sheath.
"Kim? What's wrong?" Lili asked. She sat up and then gasped as she looked where her girlfriend was staring. "Oh heck! Kim! Is that- is that a-"
Kim grabbed at the sheath. She moved it aside and stared down at the glistening lips of her pussy beneath the strange new appendage.
"Oh god, Lili, it's- it's-"
Her eyes swept from her sheath over to her girlfriend. She meant to look up into Lili's eyes, but she stopped.
"Lili..." Kim rasped.
"What?" Lili asked.
Once more, Lili followed her girlfriend's gaze to stare down at her own crotch.
At the spade between her thighs.
"It's- It's- It's-" Lili stuttered. She reached two fingers down but they hesitated an inch away from the sticky black flesh. "Kim, I have a pussy. Kim! Kim, I really have a pussy!"
"Shit, Lili, you do! Wait wait wait, is it just- is the magic from the collar just not done yet?" Kim asked.
"Maybe it'll stay," Lili said hopefully. "Um. Just. Like a human pussy, though. Maybe I'm not done changing back and it'll go back to a human pussy but stay like that."
"Maybe," Kim said softly, not wanting to give her girlfriend false hope. Her own eyes returned to the strange sheath. The red cock slipped back inside and she shivered.
She wanted to touch it, like she had before she'd mounted her girlfriend.
No, not mounted, she told herself. I fucked her. I didn't- I didn't mount her.
And yet, the words had flowed and, as she concentrated on the memory again, the sheath swelled and her cock slid out, throbbing and aching for her touch.
"Wow, it just kinda came out," Kim said. The sheath pulled back until the cock was fully extended.
"Oh," Lili said while staring down at her girlfriend's dick. "Wow. Uh. That. That was inside of me."
"Yeah, sorry, it was just- oh fuck!"
Lili leaned down to kiss the red cock before licking the shaft.
"No no no no wait!" Kim said but Lili opened her lips, raised her head and took the head of the little dick into her mouth.
Lili had never sucked a dick before, but Kim had taken care of her many, many times and she had a rough idea what to do. In her mind, it was a giant clit. And, anyway, it belonged to her girlfriend and she loved her girlfriend. Lili pressed down until her lips were buried in Kim's pubic hair - until they touched skin. The tip of it almost tickled her uvula but fell short.
Kim groaned and clawed at Lili's hair, pushing and pulling while gently thrusting up into her girlfriend's mouth.
"It's so weird but so good, Lili," Kim moaned. She clenched her pussy muscles as Lili continued to move her head and drops of clear liquid seeped from the lips.
Lili pulled off to lick the shaft while looking up at her girlfriend.
"I- I want it inside of me again," Lili said. "In case my pussy doesn't stay. I want to feel you inside of me again. While I'm human. Mostly- mostly human."
The hint of the aggression Kim had felt earlier reared its head and Kim's fingers clenched briefly against Lili's hair. She pulled the girl off and then slid from the couch to push her panties and slacks down.
"Lean over the arm of the couch," Kim demanded and she pulled at her fur-covered blouse.
Lili was quick to obey, standing and rushing over to the end of the couch before bending over. Kim reached back to undo her bra and she sighed at the release before dropping it to the floor. Her cock bobbed before her while her pussy drooled, sending lines of her cum streaming down her thighs when she walked over to her girlfriend.
Kim stood back as she clenched her hands in the other woman's ass cheeks, rubbing and massaging and spreading them. She took her own cock and bent it, guiding it towards the center of Lili's spade. The young woman stared in awe as she watched the lips open around her.
"God, it feels so weird and good," Kim whispered.
"Just-" Lili moaned. "Ohhhh just feels good over here oooohhh yessssss. Like you're stretching me out. Filling me. I can feel you inside of me, Kim. You. I can feel you inside of me. Inside of my pussy. It's better than anything I could've imagined."
Muscles clenched around Kim's cock as she pushed into Lili.
"I'm doing that. I'm doing that," Lili panted as she tensed herself. "Say it. Say it again."
"Say what?" Kim asked.
"Please, just say it," Lili begged. She reached for her nipple to squeeze and pull at it as if she were milking it. "T- tell me. Tell me you're- you're going to breed me. Tell me again."
Kim smiled, a sharp, feral grin that touched her eyes. She pulled out partially and then slammed back in and the grin grew harsh when Lili cried out. Kim leaned over her girlfriend's back.
"Oh, I will," Kim nearly growled. "Breed you."
"Yes!" Lili yelled. "YES!"
"Breed you like a bitch in heat," Kim continued.
"YES, I AM!" Lili screamed. "I am! I am! I'm your bitch! Yes! I want it! I want your puppies!"
"I'll give them to you," Kim said as she began to pound, her crotch smacking into Lili's ass hard enough to leave red marks. Her own pussy was sopping wet as her cock slid against Lili's clenching muscles. "A whole litter. I'll breed you until your tits are dripping milk. I'll-"
They fucked throughout the afternoon and evening, resting when needed but exploring Lili's new endless orgasms. Kim was disappointed when her cock softened and refused to leave its sheath after a while but Lili just laughed at her before switching to licking her girlfriend's pussy and kissing her soft, fuzzy sheath. The cock made brief appearances periodically throughout the night until they passed out at some point past midnight, exhausted and sore.
---
Lili stared at her phone when it buzzed beside her keyboard. She glanced around to ensure nobody was standing nearby or walking past her before waking the phone and opening the message from her girlfriend.
A picture of a pointed, reddened cock greeted her, along with a message: Now I get it. It just gets hard sometimes. So weird. Well. No, I was thinking of you. Mounting you again. Wish you were here. Might masturbate in my car at lunch. Or the bathroom. Never done that before. Just so hard and needy.
She touched her lips and trembled as she continued staring at the picture. After a few moments, she realized she was squeezing the muscles within her pussy and her panties felt wet against her thighs. Her pussy hadn't gone away and it was still a dog-like spade that caused her to occasionally adjust herself in her seat to keep from rubbing it. To keep from humping her chair.
Despite masturbating just ten minutes ago, she shivered as her blouse brushed her overly sensitive body, reminding her of her arousal and need. Glancing around once more, she slipped her hand beneath her skirt to feel herself and she moaned as she realized exactly how wet she was.
It was addicting. She had almost stayed home, but she knew Heather would push to fire her if she didn't show up after what happened yesterday. And so, she sat at work, consumed with thoughts of last night's endless sex. It wasn't yet noon and she'd already orgasmed four times - just at work.
Her collar was in her purse, but she didn't dare put it on even though the pull of it was a physical force. The way it simplified her entire existence while putting her in heat was absolutely sublime.
Tonight, she told herself. She hadn't worn it since showing her girlfriend what it did to her. Tonight. In the meantime...
Lili stood while holding her phone against her hip. She stared directly at the bathroom door as she made her way there, sneaking into a stall before lifting her skirt and pushing her panties aside. She took several pictures - one of just her spade, one with her fingers deep inside, and one where she spread the swollen, dark lips. All three were sent to her girlfriend and then she scrolled back to the picture of the cock to stare at it while thrusting her fingers deep inside. She raised her arm to bite at her blouse to keep herself quiet but the schlicking sounds of her fingers splashing through the dribbling pussy were loud enough to fill the bathroom and she almost screamed when she came with her feet drumming an erratic rhythm on the ground.
---
They both stared at the collar where it lay on the couch between them. Both were naked and Kim's cock bounced lightly, free of its sheath.
"Do- do you think I'll change again, too?" Kim asked. She wasn't sure if she hated the idea of it or not.
"I dunno," Lili said. She reached out to take the collar and their eyes followed it when she undid the buckle.
"What does it feel like?" Kim asked.
"Good," Lili told her. "Like. The world just fades away. All of the complex stuff just vanishes. Stresses and thoughts and emotions, they just go. Leaving everything simple and nice. Kind of like being drunk but not really? And- and- um. The dog stuff. Like. Um. The dog stuff comes up, too."
"'Dog stuff'?" Kim asked with a curious look and a single raised eyebrow.
"Y- yeah," Lili answered. "L- like-"
"Like calling you a 'good girl'?" Kim said in a low, sultry voice while leaning forward.
Lili shuddered and gasped with wide eyes. "Oh. Oh yes. I- I guess that-"
"Telling you what a good girl you are?"
"Mmmm yessss," Lili moaned. She rocked forward to her hands and knees, inches away from her girlfriend's face.
"You're not even wearing the collar yet," Kim pointed out. She brushed her cheek against Lili's cheek and her lips touched Lili's earlobe. Kim's left hand touched her cock and she squeezed it while brushing her pussy lips with her ring and pinky fingers. "You really are just a bitch in heat, even without it, aren't you?"
"Oh! Oh! Yes! Kim, yes! I am!" Lili gasped.
The effect was staggering. As her girlfriend had pointed out, she wasn't wearing the collar but the words pierced her, clawing into her mind and body. Her spade opened, slightly, and then clenched closed and a string of clear liquid slid down the curved tip of her hood to dangle and swing beneath her. Her changed pussy wasn't the only lasting effect, it seems, nor was the fur on the back of her neck that Kim had helped to shave that morning - the mental effects were beginning to show themselves.
"You want me to mount you again, don't you?" Kim whispered, saying the word more for her benefit and imagination than for her girlfriend. Her lips trembled and she started to pump herself faster.
Rather than answer, Lili quickly brought the collar to her neck. Her fingers shook as she buckled it and then she whined, a true animalistic sound as the shroud settled over her body.
The itch within her stomach - the one she'd felt early the day before - returned and she sat back to stare at her body - to watch as she changed.
"Oh, shit," Kim groaned. "I can feel it, too."
The tightening sensation was back and Kim clenched her jaw as goosebumps lifted over her back. The urge to thrust into her girlfriend - to grab her and pump and pound and dominate her was a sudden, powerful physical need that flowed throughout her.
Lili pawed at her stomach. Her unpainted nails darkened as layers of keratin flowed over them, creating bulges while the tips folded into rough points. Skin loosened along her palm and beneath her fingers before filling out into thin padding. She moaned and arched her back while grinding her lengthening fangs back and forth.
Tiny cramps, smaller and less painful than the ones that preceded the growth of her womb, sliced through her stomach. Milk ducts built, joining the ones that had grown yesterday while lobules and fatty tissue formed. Her padding pulled at six tiny patches of loose skin on her belly - skin that darkened and grew wrinkled.
"Oh!" Lili gasped when her hips popped. Her spine cracked with a blinding jolt of pain that lasted barely a second. For that brief moment, her legs collapsed loosely to the couch. Nerves reconnected and she kicked as tendons tightened and shifted while bones crumbled and cracked, forcing her legs to shrink and shift.
"I want you," Kim gasped. Her cheeks were bright red and she trembled as she stroked herself while watching her girlfriend change. Gone was the horror she'd felt yesterday, replaced by the intense desire to fuck the dog girl and feel her fur against her body. She wanted to lose herself in her girlfriend's body - wanted to lose herself to the urge to rut.
"W- wait. Until. Finished," Lili moaned.
The skin around Lili's calves was shrinking as the bones dissolved within. There was a burning sensation alongside it but the pain was thankfully absent. She stared down at her legs and wiggled her toes when tan fur sprouted between them. As with her hands, her big toes dangled to the side, held in place when her arches lengthened, shoving her forefeet forward. Skin swelled at the bottom of her toes, growing into black, bulbous padding while her toenails bit into the flesh beneath and curved outward into dense, anchored claws. Her big toes pulled against her expanding feet, vanishing into the flesh while her thumbs compressed and their claws curved further into dew claws.
The bones broke away in Lili's heels while the skin darkened. As her legs continued to shorten, her heels retreated in the shifting mass of skin until they were rough carpal pads at the back of her paws.
Her legs ached as they finished changing and they refused to stretch out naturally, instead curving at the knees to naturally bend with her thighs and long paws dangling to the side.
Lili's tongue lapped at her blackened nostrils when they pushed forward, thrusting outward along with the surrounding flesh to show the hint of her changing muzzle. The tips of her pointed ears slid through her hair while fur began to spread over her cheeks.
The smell returned. She huffed and whined and inhaled, breathing in the milky scent she'd caught the day before. Looking down at her body, she caught sight of the loose skin twisting while pushing outward.
Drops of semi-translucent milk appeared in the center of two of her growing teats before tracing lines over the bare skin on her belly, wasting away to nothing before they touched the fur creeping over her back and sides.
Lili whined again and then glanced up at Kim when she heard the woman grunt from an orgasm. She could smell her girlfriend's spasming, dripping pussy. It was strong enough with her powerful sense of smell that it was almost like she had her muzzle shoved inside of the other woman's pussy. She glanced away from her forming teats to stare at Kim's cock.
It was bigger than before and drool filled Lili's expanding muzzle. Kim's cock was at least six inches long now and girthier than yesterday. Two small bulges stood out on the base of it.
"Oh. Ohhh!" Lili moaned. Her hips rocked as if she could feel it inside of her. "Knot. You. Knot."
The words were difficult. She could remember how to talk, mostly, but the words got lost on the way to her mouth and it was getting harder to think and speak the more she changed. It was as if she were taking a backseat to the dog she was becoming.
"Can't. Can't wait much longer, Lili," Kim gasped. She had one hand on the couch while pumping her lengthening cock. Her fist bounced against her knot as it slowly inflated. "You have teats. Like a dog. Can't stop thinking of what they'd look like with a belly full of puppies. Dripping milk. Can't-"
Kim moaned and leaned forward, clawing at the fur spreading over Lili's small breasts as she took a teat in her mouth. She sucked hard against it while rubbing her tongue over it, rolling it into the back of her front teeth before biting at it.
Lili whined and whimpered and writhed. She reached out her hands, scratching Kim's scalp with her stubby, clawed fingers while Kim took her time with all six of Lili's nipples, leaving each of them erect and aching before going for her nipples.
Kim felt frantic. Her brain burned along with her flesh while her hips rocked, humping the air until she lowered herself to grind her cock against the side of Lili's spade, trapped against the distended, velvet black flesh and the fur covering her crotch. Kim's breasts rubbed against her girlfriend's breasts - rubbed against the thick fur spreading over the other woman's chest and tits.
"Wanna breed you," Kim gasped. "Need to. Need to breed you, Lili. Need to fill you with my cum. It aches. It aches so much. I need to let it out. Inside of you. Need to mount you."
Unlike the day before, the words weren't teasing dirty talk meant to rile Lili. They flowed from Kim's mouth, snatched from her subconscious thoughts. Straight from the primal urges pounding throughout her body.
"On all fours. Get on all fours. Raise your ass. Your pussy. On all fours," Kim nearly growled. She was sweating and shaking. She shoved her mouth against her girlfriend's muzzle, sticking her tongue past Lili's fangs while Lili's broad tongue unrolled and threatened to make Kim gag as they licked each other's tongues.
Lili turned and Kim sat back. She watched as Lili slid from the couch, down onto her front paws before letting her shortened back legs fall to the floor. She stood naturally on all fours now, with her shifted hips and legs holding her upper body at a slight angle compared to a real dog. Fur nearly completely covered her muzzle, but the hints of her humanity showed in her eyes and other features.
After taking a few steps, Lili lowered her chest. A few drops of milk dripped from her teats to the floor until the flow stopped. Until she was properly pregnant.
Kim stood in front of the couch while staring down at the presented spade. Her eyes were wild as she squeezed the bulbous knot on her seven inch long cock. The head was slanted with a slight point and she moaned as she ran her fist over the shaft.
Clear liquid covered her thighs from her pussy. She'd orgasmed twice during her girlfriend's transformation and she could feel it weakening her cock, threatening to make it grow soft, despite the disconnect between them. It had happened the night before and she refused to let it happen again until she'd left her girlfriend a drool, twitching mess.
"Gonna mount you," Kim said. She stepped up to her girlfriend's legs before leaning over, forcing Lili's tail aside. It was heavily furred with long black and tan hairs that swayed in the air as it thumped against Kim's body. "Gonna breed you, Lili. Breed you like a bitch. I can feel your heat against my- against my cock."
It was true. As Kim's dick rubbed against Lili's spade, heat radiated away from it. She moaned as she felt Lili's cum smearing over her shaft and head and knot. It ached with the need for release - with the urge to shove deep into her girlfriend. As if it were a sentient being separate from her.
Lifting her hips, Kim gripped herself to press the tip between Lili's pussy lips. She let go and then pressed her body into the fur on Lili's back, nuzzling into her neck as she slowly thrust into her girlfriend. It took an immense amount of concentration not to immediately push as deep as she could.
Lili's paws scrambling against the floor. She howled and shook as Kim's cock split her in half. "Big! Biggerrrr! Biggerrrrrrr!"
Clear liquid spilled out of Lili's pussy and Kim's own cum mixed with it before falling to the floor beneath them in a spreading pool
"Can't. Hold. Back," Kim moaned. Her girlfriend gripped her length the entire time. That sensation plus the feeling of fur teasing her nipples, combined with the thought of properly mounting her mate was driving her wild.
Mate, she echoed in her mind, shivering at the thought of the word. Need to breed her. My pups. Mine.
Kim pulled back and then shoved forward, pushing Lili against the floor due to the lack of grip from her paw padding. The dog girl tried to dig her claws in but it was only partially successful and she moved again when Kim slammed back into her.
After adjusting to her girlfriend's size the night before, there was pain again and it worsened when the knot stretched her further as it threatened to force itself inside. No. As Kim desperately tried to push it inside in a mad, animalistic rush to knot her girlfriend.
Despite the pain, Lili could feel her orgasm coming. The larger cock rubbed against every nerve within the whorls of her new pussy and the very idea of being mounted - of being bred like a bitch pushed her closer and closer to the edge.
"Gonna breed you, Lili, fill you up, fill you with my cum," Kim panted as she rocked her hips, meeting Lili's backward thrusts to force Lili's lips to spread around Kim's knot. "Round belly. Leaking milk. From. From your teats. And nipples. Gonna. Gonna breed you. Take it take it take it take it OH GOD take it like a good girl!"
Lili spasmed as she came, clenching against her girlfriend's cock while shoving her shaking, trembling ass back, matching her girlfriend's pounding even though the pain of it made her groan. She growled, flashing her fangs while her ears canted down and her small breasts quivered beneath her, hidden within the fur on her chest.
Kim's arms wrapped around Lili's chest and her teeth bit hard into Lili's shoulder as she forced her down. A second orgasm crashed into the dog girl. Her quivering pussy relaxed for a fraction of a second and the knot slipped inside of her.
"Fuh- Fuh- FUCK!" Kim screamed.
She pounded Lili into the floor with powerful, sharp thrusts that threatened to bruise Lili's cervix. Lili snarled through the pain but still pushed back as an immense orgasm began to build. The urge to breed was too strong to ignore for her bestial mind. Her tongue flapped, flinging drool while their cum splattered against the floor, Kim's skin, and Lili's fur.
Lili snapped at the air when the new orgasm exploded inside of her. Her breath was forced from her lungs as her entire body clenched at once. Kim's knot was pressing against her hidden clit as well as the ridged lines of her g-spot. A roar filled her ears while black spots exploded in the corners of her narrowing vision.
Kim shoved herself as deep as she could, knowing what was coming.
Deep within Kim's pelvic floor, newly formed testes, nestled next to her ovaries, released sperm. Kim felt something strange tightening within her body, followed by a thin rushing sensation that flowed through her cock to splash against her girlfriend's womb. Kim's eyes bulged. She tried to stop it - tried to restrain herself but her cock twitched and swelled over and over, drilling into Lili until Kim could feel the slippery mess of her own sperm against her swollen knot.
"Ah-! Ah-! I-!" Kim gasped until her pussy clenched with a secondary orgasm, combining the two to make her strength fail. She groaned as she collapsed against Lili and then rolled, pulling her girlfriend with her where they were connected by Kim's knot.
Kim reached out a weak arm to slide it through Lili's thick fur until she found Lili's breast. She pulled herself against her girlfriend's back with her face rubbing the ruff on Lili's nape as she panted and twitched. Lili whined happily with her tail occasionally thumping against the floor and Kim's side.
After a few minutes, when she could trust herself to move, Kim unbuckled Lili's collar to pull it away. Her knot deflated slowly and milky white cum gushed from Lili's pussy.
"Whuurrr-" Lili tried to say. She gave up and licked her pale lips as her muzzle shrank. With a face half covered in fur she tried again. "Whurr wuz that?"
"I- I came. Real sperm. Inside of you," Kim said while blushing. She reached down to wipe some of it away from her cock, suddenly terrified at the thought of it getting inside her own pussy. With nowhere else to put it, she wiped it on her leg.
Lili wiggled. Her tail was half its length but it still moved, wagging as she slowly rotated with her uncoordinated dog legs. The girl huffed and inhaled and then reached her tongue out to lick her girlfriend clean. Kim groaned and stroked Lili and then moaned when clawed fingers gently rubbed against her pussy lips while Lili took the entire cock in her mouth.
It took barely any time at all before Kim came again and, once more she felt the release of her sperm, causing Lili to gag for a moment until she began to swallow the thick load.
"S- s- sorry," Kim groaned.
Lili pulled away and her small tongue circled her lips. She laughed quietly. "Oh, don't worry. You'll learn some control. Eventually. It's always hard the first time, buddy."
"Hah. F- fuck you. I love you," Kim said.
"I love you more," Lili said. "I mean, obviously, how many women let someone cum in their mouths? That's pretty intimate."
"We should probably get something for, uh, that," Kim told her. Her cock slowly retreated within its sheath. "Down there. Uh. My stuff down there. They make pills for it. And. Um, maybe get a condom. If they make them for dog cocks. Whoa. That's not a search I'm putting on the Internet. Hah."
"Oh. Yeah. Probably," Lili said while slowly stroking her belly and the teats that still remained. She pinched one and moaned. "Wouldn't want to get knocked up. That'd be hard to explain. 'Mom, dad, I begged my girlfriend to breed me so she did. Also, I have a pussy now. Kind of.'"
"Haha, yeah," Kim said but her eyes were focused in the distance as she pictured Lili with a round belly, on her hands and knees, covered in fur, whining to be mounted. "Could- could you imagine?"
"Yeah. Yeah, I could," Lili said softly.
"Wanna- wanna go again?" Kim asked. As if summoned, her cock slid out of its sheath, pushing the furry skin down. The head of her dick rubbed against Lili's ass and the other woman moaned.
"God, yes, please," Lili panted.
Kim rolled to her back. "I want you on top. Practice riding me."
"O- okay," Lili said as she groaned and moved, lifting a soft leg to straddle her girlfriend.
"Raise your hips, take my cock and put me inside," Kim told her. The aggression was returning and it filled her voice to give it a hint of command.
Lili did as she was told, moaning as he gripped the thick cock and then licking her lips as she adjusted her hips and the head to find the opening of her spade. It took a moment or two and then her eyelids fluttered when she lowered herself onto it.
"Ahhhhh goooood girl," Kim cooed and she smiled when she saw the immediate effect of the words on Lili. The other woman whined and leaned forward to lick Kim's mouth and cheek while forcing the cock deeper inside. All without wearing the collar.
Kim pulled her girlfriend closer as Lili inexpertly tried to find the right way to move her hips.
"Do you know why I want you on top?" Kim whispered with her lips right next to Lili's ear. Lili shivered as the hot breath coursed over her face and neck but only whined and moved her hips faster rather than answering.
As Lili began to speed up, Kim gently pushed Lili to make her sit up straight. She looked down her body, briefly, to watch her cock - already slick from her girlfriend - sliding in and out of Lili's pussy with the black lips spreading over her spade. Kim reached her hands out, one up to Lili's breast and the other to her stomach.
"You'll need to get used to it," Kim continued and she pinched Lili's nipple, causing the other girl to momentarily lose her rhythm. "When your belly is full of my pups."
Lili bit her lip. Red flushed over her chest and up her cheeks. Her hands clenched against Kim's breasts while her ass jerked and her pussy clenched against Kim's cock. The woman's nostrils opened and closed as she held back from moaning through the sudden orgasm.
"Ohhh, good girl," Kim said, raising her hand to gently cup Lili's cheek. "Again. Keep going until you make me cum. Until you take my seed deep in your womb like the dog you are."
"AHH!" Lili cried out as she raised her ass and slammed it down, clawing at her girlfriend in a mad rush to make Kim cum inside of her.
Desperate to have her womb filled once more.
