(to answer any questions, before you continue none of this is canon to Layla Softpaws. I have permission to use her, and this is more or less an idea of what would happen if the two ever met)
Silence grumbled as his eyes slowly opened his dull gaze peering about his new surroundings. He was a small black-furred vulpine. Was shifting around a bit as he slowly stood. His tails were a bright pink color that quickly contrasted his body. Making them seem as if they were their own entity.  This wasn't untrue as their pink color referenced his ditto part. The vulpix was a hybrid pokemon. He was part vulpix and part ditto. This did give him the power to change shape and a few other hidden skills we might get to see later. 
He would slowly roll from his back. Wondering how he had gotten from his stomach to his back. As he rolled his sheath poked the small green tip. Revealing the tip of his fox hood. However, it was at rest and surrounded by the black sheath and the two warm round balls that followed beneath. Nice and heavy with their own essence. He would start to move soon letting out a loud yelp of pain. His eyes tearing up as he rolled back to his back squirming in place. His eyes closed as he struggled to stabilize his body on his back. He would bend forward looking to see both his hind legs wrapped in a thick black bandage. He was now feeling the throb of his hind legs. His ears lowered as he struggled a moment to move his head closer to his feet.  The fox finally positioning himself to touch his paw with his nose. 
"Stop squirming, your wounds won't heal properly if you try to move around too much," Layla said with a smile. The large black vixen was easily more than a dozen times his size. Her fur was black, but instead of being smooth like and silky like Silence's it had an almost dusty yellow color to it. The fur was much rougher in appearance than his.   Her tails were a rusty yellow color. His eyes would trail below her, he could see a pair of massive balls. Black like the rest of her body. However, they seemed much smoother. He was close enough that he could hear the swishing sounds that they made when she shifted her tails. They were full and not just with a little bit of juice. Only the tip of her black member was free. So he couldn't really judge how big or small she was at the time.   He also wouldn't be able to see the colorful piercings lining the bottom side of the shaft. 
Silence would pause and begin to examine the room he was in. It wasn't his den, nor any of the patches he usually slept in. As he looked around his eyes began to widen. He could feel his throat tensing up as he noticed how small he was in comparison.  He was in a room meant for someone much more massive than him. 
     Silence tried to curl inward letting out a whine as the pain from his hind legs would become apparent again.  Space set for someone of a much larger size. The bed alone minimally capable of fitting a dozen of him each in their own comfortable area. He, however, had noticed a lot of it was either black or untouched. The carpet seeming just as mottled as her fur.  He would at least turn to face the source of the voice. Not even noticing he was underneath a black blanket the whole time. A few rapid steps to push the thick fabric off himself he would eventually be free. The stale air being replaced with something he didn't expect.  He coughed rapidly as an overpowering scent filled the air. The thick air harder to breathe as the smell seemed to dig into his head. It was like a small fire spreading itself into his nose. The overpowering musk strong potent and bitter like a male but also had a female's floral sweetness to it.  As well as a back scent of pneumonia. He attempted to cover his nose to mask the smell. Unable to grab at the blanket. 
    His attempt was stopped at a golden tail would curl under his neck. Blocking the paws for the moment from reaching past them. The tail was forcing a far more potent version of the scent into his nose. This forced Silence's eyes to water.  This scent had a secondary effect that would make both his vulva and cock shift in place and tingle lightly as they revealed themselves more clearly. He moved a bit to get comfortable. Silence is a hermaphrodite. He prefers to see himself as male and will avoid anyone touching his vulva. This has actually been a reason for him to bite or attack someone even though he usually is passive. 
      The smell of her massive tail radiated around him. Layla spoke in a demanding tone, "Get used to it!, There's no point in trying to ignore it. You won't be mobile for at least another four weeks. You will have to deal with my natural scent for that time. " She paused for a moment before her stern expression vanished entirely replaced by a much gentler and friendly one. She would continue with a warm smile,  "Well since I have you here, I suppose introductions are in order.  My name is Layla Softpaw. " 
In response, the black vulpix laying in place would look up at her. The sheer size difference between the two being reminded of him as he replied, "M-my name is Silence."  His ears began folding back nervously in response to her size. 
Every aspect of her overpowered him. How just a tail could hold him in place. How each of her violet eyes gazed down. Their glow was ominous and overwhelming. Even her scent far overpowering his own as he finally was able to settle his throat. However, this entire thought process would be interrupted by, "Grrurrgle!" his stomach bellowed. He didn't know when he showed up but it had been a poor hunt, and he hadn't had much to eat as of recent. 
She looked at him with a gaze that almost seemed motherly.  "Cute, if you're hungry I can take you to the kitchen, and we can get some food. " She would say gently,   "Though I have a small request," She paused a moment before smiling nervously,  "More to keep me out of trouble. Would you mind signing something for me when we get out there?"
Silence paused for a moment thinking about it he wouldn't have even expected any knowledge of contracts from another vulpix. He paused before asking his own red flags starting to raise, "What am I signing exactly?"
Layla's expression seemed to lighten up, "it's nothing fancy, just permitting me to take care of you. That way if anyone poses any questions they know I have your permission."After a brief thought from Layla, she smiled and held up a paw.  Actually, let's get that out of the way now. " She would flick her paw as a paper appeared from nowhere on her paw. It seemed oddly aged as the page was yellow and the document itself curled. Almost as if it was made from a leaf. He would examine it for a moment his Dichromatic eyes reading down. 
It read as follows
"I agree to allow Layla Softpaws, full custody of me until she deems me ready to be on my own. I will remain obedient and respect anything she might say. As well as follow any instructions unless they cause me harm. 
Signed_________
 It was just a temporary situation so he would press his paw into the white ink pad that seemed to have replaced one of her digits. He would feel the wet, cold ink cover his paw. However, suddenly a sharp tingling overcame his paw as the ink grew warmer.  He pressed his paw to the paper. Unaware he was signing in his own blood. The red mark was seeming to contrast the yellow. She would smile and seemed to make the scroll disappear after he signed it. 
She looked down at him and smiled, "Well I have a few options on how to move you since I can't just carry you." She paused a moment before smiling softly, "Bear with me on these they're the only ways I can safely move you without hurting you. I can carry you in my mouth or in my sheath."
He paused a moment pondering the options, and when he opened his mouth to speak, he said, "Sh-sheath." he paused a moment feeling he meant to say mouth. He would shake himself off and speak again, "I meant to say sheath." he paused. He would look up wondering what was going on. Her musk was making his head feel a bit fuzzy, but he thought nothing of it for now and figured he was still waking up.  Her eyes would focus as the fox was lifted up and carried backside down. He felt his body moved through the air. The fox whining as he saw the skin over her sheath Tug open and reveal more of the black member inside. He could feel the fire in his nose suddenly become an inferno as his coughing fit started again. This was nothing like her tail. The bitter and powerful intensity filling his head with warm sensations. The thick skin that made the larger pokemon sheath would pin him so his muzzle would rub against the larger fox's cock. The fox pawing at the underside as he struggled to shift himself more comfortably. The thick musk and some of the gooey smegma forced into the fox's nose. She would giggle as she said, "Relax and quit trying to fight it.  I promise if you do that it'll become quite pleasant." Silence found his paws obeying her words as he stopped kicking or struggling.  His body relaxing into her cock. He would, however, rub his nose to clean some of the gunk off. His ears perked as he blushed deeply. 
Layla would walk in a manner that forced her sheath and sack to sway. This, in turn, pushed and ground his muzzle and his entire lower half to rub and slide onto the others member. The colorful studs on either side of him were keeping him from sliding too far to either side. He didn't know how but they also seemed to keep him from slipping out. He was essentially in a small fleshy cage made of her cock and sheath. The piercings much like the bars of the cage.  However, the grinding forced a fresh and slowly increasing musk. This made it hard to breathe.  The thick scent was invading his nose and going past it. All the way to his mind filling it with a sweet musky fog. The fog only growing thicker and thicker over time.       Layla would
 grin and sit down as he felt her move he would feel the impact of her sitting and feel his body sink further into her sheath. He heard the sound of her teeth grazing at the fur under her tails. The audible brushing noise of this filling his ears. He tried to climb out his paws slipping on the cock in front of him. As if something was holding him in place. He would blush deeper and whimper as the scent made things worse. 
    "Don't worry I just need to take care of this itch then we'll get you downstairs for your lunch." her chewing motion made her sheath wiggle forcing him to grind over her member with his own. His member sliding free as he was inside her sheath. She could feel it and would give a light grin. She knew it had started. 
     No one else would notice since to the outside they couldn't see much more than a small bulge at the base of her sheath. She would soon finish and stand back up. The grinding motion had almost wholly fogged the fox's mind with pleasure. A need to both give and receive more. The fox inside having begun to lick at the underside of her cock. The instinctual and passionate bath he was giving her monstrous rod only made her murr.  He didn't understand what was driving this, but the taste made him want to push his tongue against it once more. The smell only seemed to make him grind his cock against hers and the feeling of her cock in his paws and her piercings holding him in place. It seemed right. His whole body shivering as each lick only pushed him further into her trap of need and desire.  The forced sensation was making him whine out needily.  
    He would blush as he felt her body add to the sensation. Soft moaning audible from her moving sheath as she giggled before saying in a sultry and teasing voice,  "No matter how much pain one is feeling, their lust and need can always overpower it. She kept her light trot soon reaching the base of her stairs and turning to the nearby kitchen. 
    She could feel a warm and gooey substance after she stopped. Although to her maybe no thicker than an appropriately sized needlepoint.  She would pause and look at the table. After brushing some stuff off the table. She smiled satisfied with the spot.  Her eyes focused again glowing a little brighter as she would pull the needy black todd out and laugh. She could see the strand of precum trailing from his cock. Her musk could sometimes increase the amount of cum in someone. This seemed to be one of those cases as the trail was quite long meaning he had produced a rather impressive amount.  The small fox was panting and looking to her. His pink tails splayed as his cock stood at full mast for her drooling its precum almost in a steady stream.  Layla would laugh and run her tongue over the front of his body. The warm appendage cleaning him and replacing the juices on his body with her thick slimy saliva.   "hmm, a bit salty with a warm aftertaste." The fox getting another lick to thoroughly drench him in her saliva. He would snap back to reality and shake himself off.  Bits of spit and drool sprayed the area around him.  She squinted in response to some of it getting on her muzzle.  She sighed and would run her tongue over his front again applying a new coat before saying, "Stay still and remain like that for now." He would look to her confused as she moved to sit herself down. His body was now stiff as a board as she sat across from him. His thoughts returning to him he would lay on his side. Since he couldn't stand or sit he only had this position.   However, anything going through his head was interrupted by the feeling of something pushing his tails back. He watched her as she moved her paw closer a smooth nail slowly extending.  However, the claw was at least twice as thick as his digit and maybe half as thick as his tail.  She was well groomed. It was as if many people cared for her on a constant basis. With her size, one might consider her a goddess. 
Her nail began to push its way into his vulva. His ears are lowering as he barked out to her. His hind paws were kicking at her hand to drive it away. This reaction forced the fox to cry out in pain as he was reminded what brought him here in the first place.  His legs were throbbing as he looked to her confused. 
"D-don't touch there!" he demanded as his eyes teared from the sensation. 
"Alright hun, you need to relax.  I understand I did take a small dip in your mind, and I know you don't like sharing that. However, if you let that build up, it will become painful and difficult. Now I'll fix that, but you need to be more trusting. Do you understand." she looked to the recovering fox watching him shift a bit as if he had something wedged in his hind legs. She had been getting into the action as he could clearly see the piercings lining her erect member.  They were, colorful. Was really the only thing that came to mind. 
He tried to pull his tails to hide his vulva both of them able to see the light dripping from it. "N-no one can touch that." he would say lightly shivering. This was what one would call a mini heat. So the need would slowly build until he was satisfied. 
At the current moment, his paws trying to hide the vulva would have the erect member poking between them. His eyes looking up in a nervous and slightly scared manner. 
     His words not matching his expression. As his paws shakily held themselves over his now wet vulva.  She could smell and see his heat as it dripped. 
    She sighed clearly annoyed with the situation, "Normally I dislike using force. However, I can't just leave you like that, so you have a choice. You can move your paws, or you can spend the time we play under my ass. Also to clarify, unlike my claw, which is nice and smooth with our size difference. My paw is different in shape and well. To sit on you without crushing you, I would have to become more accommodating in size. I wouldn't be able to use my claw and would probably need my whole paw to pleasure you as I want."
The fox whimpered as he was still recovering from the haze her musk had put him in. His tails swishing back and forth as he tried to move his body. Her paw pressed to his chest to force him back on his back. Her eyes looking down. She would smile, "Well I'm waiting for sweetie, what is your choice." 
"B-but I don't ...mmph" he would begin to say as she would move her paw one of the digits would hold his muzzle shut only allowing a muzzled ending to his statement. Her tails flicking as she grins darkly many teeth revealing themselves to him, "Dear you've said everything I wish to hear.  Now, hush" she would say as she looked to him. Moving him from the table, she would place him on the floor beneath her. Although looking rather mottled and sticky, the carpet was surprisingly soft. However, before he could overthink into this.  She plopped her cock over his body. The large phallus now pinning the fox beneath its musky length. A warm but sticky substance rubbing into his fur as she smiled, "Take in the scent sweetie, there is no fighting now." she would say. Although a pointless statement as the member had pressed to his nose. He would be taking in her musk whether or not he decided to.  Her scent causing him to cough a few times. However, after a few moments, she could see his expression dull slightly.
     "So sweet, do you like your goddess's scent. Isn't it so good how it fills your nose then your mind? So thick and musky as it slowly blocks any thought. Leaving nothing but bliss in your head, and a need to share it. Obedience is the best way to share bliss with your goddess. Now be a good boy and mistress will make sure you have lots of treats." She giggles and looks down, he hadn't noticed anything until something pressed itself in. "Also I bet you feel it now." she would tease as something began to writhe its way into his pussy.  The rounded tendril making its way deeper into his vulva. It had come from one of the piercings. However, it became more clear they weren't piercings more or less they were well they were disguised shells for the tentacles to remain dormant in. The limb was thick and slimy with her smegma. The substance almost acting as its own lubricant as he failed to hold in a loud moan. 
The moan that had escaped Silence's muzzle only let her musk invade his mind further. As he inhaled her scent. His paws pressed to her cock. She would smile softly, "Now begin cleaning your goddess' cock" she would say knowing full well the motions would cause his nose to scrape some of the built-up smegma into his mouth. This only proceeded to make the earlier effects stronger. 
     His tongue slowly moving its way over her cock as the tentacle squished itself into his vulva.  Each lick gathering up more of the substance as her tendrils seemed to move him closer to the tip. His eyes closed as he pressed his paws to her shaft. Two more tentacles each from a separate shell would emerge and grab his paws holding him to her cock as she smiled softly. "Nice and snug now sweetie. Can't have you falling." she would tease as she would sit up causing the fox to be lifted by her girth. He was at least a good two or three dozen meters from the ground now. He was right near her tip he would only hold tight to her. Two more tendrils would grab his hind paws and force a tense grasp. He could see her pulsing tip.  The tip was big enough he could fit his whole muzzle inside to plug it. However, given the circumstance and the rumbling sound. His ears perked in curiosity. Giving his currently empty mind a command, "Lick near the hole while I mark you as mine.  Make sure they are nice long licks. I want your mouth nice and open from each lick. You need to be able to accept all of my gifts." she would say as her tendrils held him firm to her cock. He could hear a rumbling as her three urethrae began to rumble with the morning release. He could actually hear
 her muscles relaxing as the floodgates opened. 
    She would giggle softly, "Time for your bath it seems." She would watch him as if enjoying a small movie. The tendril in his vulva still pumping itself in and out slowly. 
    The yellow flood rushed over his body most of it ran over his back and soaking into his fur. The remnants would be split between filling his mouth and filling his nose. This didn't allow much room for the fox to breathe. His nose still pressed forward as he lapped. Every lick giving him a mouthful of urine. His own cock grinding against hers as panted and swallowed. His belly filling with the yellow substance.
Meanwhile, his cock remained hard as each pump forced him against her own cock. The smegma near his cock had made a nice little fuck hole. It wasn't tight, but it was moist and stroked him with every pump. Sadly none of this would be enough to get the fox to climax as the whole only provided a light pleasure. The mix of her cock musk and the musk from her urine making his eyes close tight from the pleasure. The flood of urine came to a stop five minutes later. Now dripping down the side of her cock. The fox still panting as his vulva dripped from the motions. His stomach having bulged slightly from the amount. 
     "Don't worry I plan to enjoy both parts." she would giggle as she would wrap a paw behind him pressing him to her cock softly. His warm smegma fuckhole was now washed away by her urine.  "Now keep cleaning while your goddess explores her new pet." 
    He would lick over her tip getting a last mouthful of urine before his next lick would be given something else. The new substance much thicker than the urine, however, instead of the bitter, pungent flavor this one held a sweet almost honey like flavor. His fur dripped from the urine as she smiled softly watching him drink at the new substance like it was the best thing ever.  "Does it taste better?" she would tease as she began to stroke her paw over his back. 
    His eyes closed as he let out a warm murr. His muzzle going toward the hole this time.  He let out a muffled confirmation. His mind was more focused on getting more of her delicious precum. His muzzle opens and drooling the thick clear substance.  As he smiled at her. This, however, instead of being a cute expression would make him seem quite lewd. 
"Careful it's very powerful." Layla would laugh. She seemed amused as if she was watching someone take their first drink of liquor. The fox swallowed the whole globe. His nose drooling some of it. She would giggle. "How cute, already this eager. I bet it feels amazing. My scent urging you forward making your only desire to please and earn more of the delicious seed you so eagerly want. Keep licking my dear. You've been a good boy and earn your reward." she would say as she watched him go muzzle deep on his next lap.
The tendril was moving much faster than earlier its warm squelches unphased by his bath as the smegma was inside his vulva as it did so. 
His eyes closed as he swallowed the following amount. Shaking out his fur this action would bind him to everything nearby. The thick, sticky substance now spread about her paw and cock. Soon enough a different thought entered the foxes mind.
     The fox would take a deep breath. Layla giving a curious glance before watching him stick his muzzle into her urethra and beginning to drink directly. His muzzle causing a small amount of pleasure. However, like the smegma from earlier on his cock, it wouldn't be enough to get her off. Only enough to get her hot with arousal. The vixen holding him would begin to try and stroke her paw around him. "Such a good boy, that's right, drink it all up." 
    Her eyes focused on him as he lapped and slurped his head almost completely buried in her cock. His tails swaying behind him as he looked up at her his muzzle deep inside. This would cause his eyes to open much broader the new sensation was quite pleasant. However, it wasn't enough for her. She would stroke the knot at the base soon getting an idea. "Pet, wrap your tails around my knot and stroke it." She commanded her tails shifting lightly. The knot he had his footing on. 
    He wrapped his tails around her cock. The long pink appendages making a slight squish. They weren't flesh, but they also weren't fur like she had predicted. She paused a moment curiously examining his tails as they stretched themselves all the way around her cock. Entrapping the knot in a warm gooey embrace. Before she could feel a motion of rubbing over it. Her eyes closed as she purred for him. The new sensation combined with his urethral feasting making her let out light moans. 
    His eyes closed as he murred and drank the tails stretching and wrapping themselves. The sensation he felt from his tails stroking her edged him forward. His tails moving faster as he swallowed. His cock pressed firmly against her own. The tendril pushing deep enough for him to feel it pin his stomach to her cock.  His eyes closed as Layla murred.  murred her tentacles holding him firmly against her cock as the tendrils that are his tails began to stroke and pump faster. Still looking like a partial pink condom wrapped over her knot.   He wanted all she had to share.  His eyes closed as he drank in her precum more fervently than before. The sweet juice like nectar as the fox trembled as he would soon feel his own body tense up. "I see you're close my dear, claim yourself as mine and I'll let you have what you really want." She would grin and smile as she began to pant, "S-so close, such a special talent you have. I can feel the many tiny tendrils helping to massage my knot. Bringing me closer and closer to giving you a warm morning coat. " He blushed as he had minimal control of his tails and what they did. So the little tendrils were not something he had done.  He whimpers as he strokes faster his muzzle buried far enough into her tip that his ears folded back. She would smile and push one of her digits to his head forcing his head from the hole. His deep gasps and lustful expression as her cum dripped from inside and out of his muzzle. Showing just how eagerly he wanted this. 
    She growled looking directly into his eyes "Be a good boy and cum with me, my precious pet!" her eyes closed as a torrent of fire from her tip. The sheer pressure was enough to launch him as the tendrils holding him to her let go.  Her torrent and gush became focused as she stood up and the cock directed itself forward. Making the fox fly back and into a wall. The wall was soft as if she had her home prepared for this situation.  His body held in place by the torrent of her delicious and sticky cum.  His mouth was wide open to accept as much as he could. She watched as his own cock spurted in time with hers his orgasm lasting almost as long as hers. It tapered out a good hour before hers did. (Although 9 out of ten hours wasn't too bad. And before you ask I checked her info, she could definitely cum this long...probably much longer.)  
However, as they finished, he would finally slide slowly down the wall like a squid or a pickle slice. Soon dipping into the three-foot pool of cum they had both made.  His eyes closed as he murred for her the bubbles of his murring surfacing.  His body grew in size. It wasn't enough to match hers but enough so that the substantial amount of cum. Which in her case only came up to her paws. Made him a good 20 feet in height. If she were a ninetales, he would be a vulpix in comparison to her size. (this would make him a third her current size) His eyes closed as his muzzle and tongue were now big enough to pleasure her directly. Although saying that is, quite a stretch.  He would pant as she smiled and looked at him. "You will be so much fun to play with/, and I intend to get every bit of fun I can from you." She would use her tails to pull him close like a mother bracing her cub. "Now let's get you some food." She'd say realizing they hadn't even gotten the food he requested yet. 
"Queen, I'm no longer hungry. I'm nice and full" he would say as he panted and murred. He patted at his bulging stomach to emphasize his point before rolling to his feet and standing near her. He would shake himself off and blush. He smelled of her both inside and out, and he loved every bit of it.
