There is no situation quite so uniquely embarrassing as visiting a sex shop. By visiting such a place customers run the risk of being spotted by someone they know, to say nothing of the store’s wares themselves; tools and accessories capable of satiating any sexual appetite. The purveyors are invariably non-judgmental which is understandable given their line of work and the hundreds of customers they assist in purchasing the aforementioned kinky trinkets. Sex is a valuable industry. Of course what one does behind closed doors is their own business and they need not feel overwhelmingly shameful in buying sex toys which would only enhance their own or their partner’s enjoyment. 

Patrick Quinn, a college student nearing the end of that unendingly turbulent life-phase called adolescence, was mortified during his first trip to a sex shop. Lonely nights would find him in his dark bedroom in the glow of his computer screen. When one is alone with idle-enough hands nature typically runs its course. And Pat had been experimenting. On one occasion a few weeks past Pat had, in the passion of the moment, wriggled a lubricated finger into his rear. The sensation, so new and unusual, took his breath away. It was very much to his liking. After lifting some vinyl gloves from the biology laboratory Pat privately probed himself once more with excitement. The feeling of being soundly ‘filled’ pleased him greatly. After a small bit of research he decided that a butt plug would be the perfect toy for him. It would then be a few weeks before Pat would work up the pluck to drive to the nearest sex shop, the tastefully named “Pleasures.”

The store was less embarrassing than Pat had expected, but this didn’t keep him from breathing heavily in nervousness as well as sporting a bright red blush through the whole ordeal. He skirted the expansive porn section and eschewed the dildo display, though he decided he would have to explore this second area some other time. He was determined to be out of the store as quickly as possible. He soon found what he was looking for: A standing rack holding butt plugs of every conceivable shape and size. There were ribbed ones, specially designed plugs for women, even one hilarious plug which was colored like a traffic cone. Pat deliberated for a while before choosing a moderately large black plug called “Big Black.” He wanted a plug that would be comfortable, but also ‘challenging.’ He is largely built and lanky so he was sure he could take it. And he was very eager to do so. He approached the cashier and felt terribly awkward as he waiting for his ATM card to be accepted. The giant butt plug stood erect between himself and the disarmingly attractive cashier. Upon receiving his receipt he left the store immediately and practically dove into his car.

Presently Pat is driving to his shared apartment with a huge grin on his face. His head is awash with ideas. Would he dare to wear the butt plug in his daily life in secret? He would certainly use it as a masturbatory aid. He would do this as soon as he gets home, he rapidly decides. He arrives at his apartment quickly as the store is not located terribly far away. Making sure his devious toy is securely covered by its nondescript bag Pat enters the apartment building. He finds his roommate Jenn in the living room and gives the tersest of greetings before vanishing into his room. He cuts open his new toy and wastes no time before shamelessly disrobing.

Pat slathers the plug in his favorite lotion and, after manually relaxing his sphincter a bit, poises his ass above it. He tentatively presses his hole against the soft tip of the plug before eagerly lowering himself onto the toy. It feels like his finger explorations had felt, but so much more fulfilling. He pants and squirms as his ass consumes Big Black. It begins to feel so wide that he will be unable to consume it all. Patrick’s dick slowly rises throughout the process. Pat takes some deep breathes to relax his anal muscles and then lowers his butt to the floor causing the plug to hold fast with a slurp. He exhales loudly in pleasure. The rubbery toy fills him well and sitting on it as he is now feels doubly great. He sits for minutes on the floor relishing the feeling. Soon though his engorged cock invites him to proceed. He approaches his PC and thoughtfully lays a hand towel on his seat before sitting. 

Pat wanders to one of the many sites which cater to his unique sexual tastes. He is and has always been attracted to anthropomorphic animals. As many of his internet friends do Pat has a character he uses as a persona. It is a bat named Nuka. Nuka is an idealized stand-in for Pat himself and is thus completely enticing to him. He has on many occasions wished he could live as Nuka, if only for a while. He is not particularly unhappy in his everyday life but this fancy has nonetheless always captivated him. To be something not human. Pat navigates to his latest art commission of Nuka, an excellent nude drawn by one of his favorite artists, and begins to masturbate.

The going is absolutely enhanced by the new butt plug. Pat’s sphincter, unable to shut, pinches occasionally, exciting him. He gleefully pumps away before he begins to hear a voice in his head. He stops stroking only when he is able to make out the words.

“Do you really? Want to be him I mean?” It says in a barely audible whisper.

“Wha-what? What is this?” Pat says. He looks to the doorway to make sure he isn’t overhearing the TV in the other room. The hall outside his room is quiet.

“I can make it happen if you wish it.” The voice continues.

“Who said that? Huh?” Pat says. He looks around searching for a source. 

Suddenly a patch of something solid begins to appear from his computer screen. It grows to form what looks like a head, but Pat is terrified and has trouble seeing in the darkness. He falls back in his chair and notices that it is in fact the head of a canine which presently looks at him with tired and malicious black eyes.

“Are you dense?” He says. “I can turn you into Nuka if you want, but I’m in no mood for BS right now. Do you want to be Nuka or not?” The dog says this as he pulls the rest of his body from Pat’s screen. With his hands on the edge of the desk he falls forward until he lands fully formed on the floor. He is an anthropomorphic bull terrier with the breed’s characteristic ‘egg-shaped’ head. He wears only purple slacks and when he stands Pat is amazed. Pat had managed not to scream during the dog’s appearance. He sits on the floor admiring his visitor. A true-to-life anthro is standing in his room and is leaning impatiently against his desk. Pat spies the dog’s paws, he had always had a fetish for feet and paws. In his shock his gaze lingers on them.

“Patrick, my eyes are up here.” He says sternly causing Pat’s eyes to snap to his. Though Pat is too intimidated to hold the stare for long and looks away. “Do you want me to turn you into Nuka or not?”

“Uhhmm. I don’t-- Who are you?” Pat asks.

“My name is Grant. I grant wishes.” He replies tersely as he taps a paw on the floor.

“I guess. I mean you just… appeared in my room so I assume you can really do it.” Pat says, trying to understand his situation. The dog’s offer does excite him, even if his visitor’s appearance was suspiciously timely. His eyes flash to the pleasing image of Nuka on the computer screen and Patrick decides to roll the dice. “Yeah. I do wish I could be Nuka.”

“Finally. Alright let’s do this.” Grant says. Patrick immediately feels a stirring in his gut. The butt plug feels like it is swelling and changing shape. He stands and inspects it in alarm. “Man you caught me on the wrong day. You’re going to need to help me vent, alright?” Grant continues. He stretches and sighs as Pat wheels around trying to see what is happening to the plug. He soon sees the shocking reality. The inky latex material is growing, spreading all over his body. What’s more is it is forming new structures. 

“Ahhh ah! Grant, what’s happening?” Pat whispers loudly. He doesn’t want to alarm his roommate to his situation. The butt plug is now fused with the spreading second skin and is irremovable. Grant inspects his claws lazily and ignores Pat’s question. The substance spreads swiftly. His legs are almost completely covered already. His feet have grown oversized and now possess black claws. The substance adds the appearance of enviable musculature wherever it spreads. Pat’s cock and balls are swallowed up in latex and also increase in size. In his surprise Pat inspects his transformed genitals with his hands. Though when he removes his hands the substance clings and begins to spread inward from them. He grows claws on his now beastly looking hands and he watches as he is granted robust arm muscles which glisten in the half-light.

“Hey! Grant what is this stuff?!” Pats hisses. Grant finally acknowledges him.

“I’m in the mood for latex today. You don’t mind being a latex Nuka do you?” Grant says.

“That’s not what I wanted, ah-ahh.” Pat says as his wings begin to appear. A big fleshy membrane extends under both of his arms to about his waist. He also learns that his chest is totally coated and ripples with round muscles. “Woooahh.” He looks down on his changed form and finds that he likes it. What he doesn’t like however is the dog who is causing the transformation itself as Pat becomes more and more uncertain with every inch of the latex’ spreading.

“Wait. Grant stop. I don’t want this, I don’t--don’t trust you.” Pat says, holding up his clawed hands.

“Welllll, you should have thought of that before making your wish.” Grant says matter-of-factly. He removes himself from Pats desk and approaches the nearly transformed Pat. “I have to hurry this up.” He says before holding up a hand. He presses it swiftly against Pats face. From the palm of his hand more latex spreads and meets with the growing mass on Pat’s body. Pat groans and chokes as the substance worms its way into his lungs. He hacks until he realizes that he no longer needs to breathe. He can feel two huge, conical ears appear on the top of his head. And his mouth forms a muzzle filled with sharp teeth. When Grant removes his hand Pat’s transformation is complete. From tall ear to clawed toe he has become a latex rendition of his fursona.

He feels simply wrong. His body is rubbery and pliable, he has no pulse and he doesn’t breathe. The black bat falls onto his bed gasping and trying to pull at his second skin. He is shocked to find that he feels every pinch. He tugs at his muzzle and watches it extend like plastic before snapping back to its original shape. Pat’s mind is hazy. His discombobulation is more severe than even this extreme situation would warrant. He feels as though he is drunk or tripping on something. Almost as an afterthought Pat realizes that the enormous butt plug is still filling his rear. When he brings a big hand to his ass to investigate he finds that the plug has become hollow, rendering his ass an open, cavernous hole.

“Mmmm, wide open.” Grant says. He managed to disrobe while Pat was recoiling in shock. The dog licks his chops and closes in on the bat. “Just the way I like it.”

“Nnnno, this isn’t what I wanted. I don’t feel right.” Pat says. He kicks at Grant who dodges effortlessly.

“I’ll bet you’re feeling woozy? A bit uncoordinated?” Grant says with a grin. “I can’t have my fuck toy thinking straight. Think of a date rape drug. In this form you will be constantly under this effect. Nice and suggestible.”

Pat in his near delirium, can’t understand what Grant has explained. He continues to prod his body confusedly and tug at the irremovable butt plug filling his rear. 

“But I don’t like this.” Pat says feebly. Grant reaches the bat and begins to grope him. The dog roughly pinches and pulls at the Bat’s big shoulders and membranous wings. He gives the bat’s cock a few gentle strokes causing Pat to shudder and groan. The dog summons a collar and leash from seemingly nowhere and affixes them to Pat’s neck. The tag reads ‘Nuka.’ “Grant, sssstop. No.” Pat groans. Grant’s groping feels incredible, but he remains conscious enough to remember that the attention is unwanted. He attempts to crawl away from the horny dog, but is halted by a firm grasp. Pat looks back, over his swishing black tail to find that Grant is lubricating a finger with his saliva. He smirks at Pat then swiftly inserts the finger into Pat’s anus causing him to moan loudly.

“Ohhh you like that?” Grant says, Pat can only breathlessly pant as he awkwardly attempts to force his limbs to help him escape. “Why don’t you jerk off for master?” Grant says with a malicious grin in his black eyes.

“No. Somebody… help.” Pat says quietly.

“Come on. I’ll help you.” Grant says while grabbing one of Pat’s hands. He guides it to the bat’s engorged latex dick and wraps his fingers about it. The dog forces him to pump a few times before the confused bat continues to do the job himself.

“Mmmmph, but feels so good.” Pat moans.

“There you go.” Grant says absently as he has turned his attention to Pat’s cavernous rear. The rubbery bat masturbates with mounting excitement as Grant positions a fist at his anus. “Now hold still.” He adds before abruptly forcing his fist into the bat’s pliable hole. It is so widened that the dog hardly has to stretch it. Finger by finger he manages to squeeze his entire fist into the bat’s ass.

“Ahhhhh ah, no. It’s too big for me.” Pat hisses loudly. “Take it out.” The squirming bat is not very convincing as he is continually jerking off while he pleads.

“Not a chance batty.” Grant says. “I know you like having your tail hole filled so you just keep tossing yourself off.” Pat wants to argue, but can’t form the words. His mind is a tortured haze as he runs his paw-like hands over his massive dick which is spilling pre cum onto his bed. He looks back in dismay at Grant whose arm is lodged in his ass. The dog begins to rhythmically pound his fist into Pat’s ass. Pat begins to growl lowly at the amazing sensation. His ass is overwhelmingly full and stretched to its limit. He is scared that whatever material he is made out of will tear. Meanwhile his cock is shuddering with an impending orgasm.

“Too big for me master. Sssssstooop.” Pat moans as he blows his load. Gobs of cum shoot onto his bed as he lustfully humps into his hand. Grant continues to literally pound Pat’s anus. He even spreads his fingers to further fill the bat’s rear. When Pat has calmed a bit Grant forcefully removes his hand with no regard for Pat’s comfort and slap’s his bouncing and taut ass.

“Ooh you are a true slut. Just what the doctor ordered. How do you feel?” Grant asks while entwining his arms around Pat’s muscular chest.

“It was good. So good. But I want to go back to normal I think… master.” He says. His mental disorientation is growing worse. He runs a seed covered hand over Grant’s in adoration.

“No, no. Not yet. I have another job for you.” Grant says. He stands beside the bed and takes Pat’s bat muzzle in his hands. “Nuka you look so dumb and horny. I love it.” He says. Pat slowly grins as Grant lifts one of his arms to present his armpit. It is dank and hairy. Even twisted Grant recoils a bit at its stench. He points a clawed finger at it. “Sniff it, my pet.” Grant says. Pat pulls his face away causing Grant to grimace at him.

“I--I don’t want to.” Pat says sheepishly. He fiddles with his claws in anxiety. Another effect of his forced delirium is that he has an increasingly difficult time disobeying Grant. 

“Alright that’s fine.” Grant says dismissively. He then yanks Pat’s leash forcing the bat’s maw into his smelly armpit. “You don’t have to want to.” He adds.

The bat, overcome by the incredible musk and sweat, thrashes fruitlessly against his leash. 

“MMmph! Mmnng!” He groans into Grant’s armpit. His nostrils fills with his master’s pungent body odor and he sucks his non-existent lungs full of the scalding perfume. As he repeatedly sniffs the pit though he begins to become accustomed to the smell. Grant how holds his face in place with a firm hand at the back of the head. Pat at length wraps his arms around Grant’s torso and sniffs at the armpit intently. He doesn’t truly want to do this of course, but his diminished faculties force him to comply with Grant’s desires. 

“There’s a good bat. Look at you, more obedient by the minute. Now lick it.” Grant says. Pat looks up at Grant in first confusion and then dumb compliance. The bat frees his nose from Grant’s armpit briefly before opening his muzzle and dragging his broad tongue over the reeking zone. His mouth is filled with odiferous sweat. Grant grins wider than Pat has yet seen him do. He watches with glee as Pat repeatedly laps his hairy pit.

“Ok. That’s enough. Geez you stink.” Grant says hurriedly. “On the ground. Now.” Grant yanks Pat as he crawls to the floor. Pat sits before Grant on his knees. The dog hops onto the edge of the bed before lifting one of his paws in the air. Pat is thoroughly hypnotized at this point. He follows the pads of Grant’s paws as they are swished before his face.

“You like paws, don’t you slut?” Grant asks.

“Yyyess master.” Pat says.

“Good.” Grant says. “Lick.” He presses one of his large paws into Pats’ face and smothers his nose and mouth. Pat wastes no time in following his master’s order and begins working his tongue into the crevices of Grant’s canine paws. He derives no small pleasure in running his tongue over the robust, bulging pads. Grant is growling in pleasure. “Ooo hoo hoo, I love having my paws licked. Fuck yeah bitch.” The dog takes his throbbing dick in hand and begins to masturbate sensually. He puts his weight on the paw Pat is licking causing it to engulf most of the bat’s face. Pat however is happy to be of use and is overjoyed to be licking an anthro’s paws. In this twisted way one of his greatest wishes was granted, though internally he is screaming for control over his own body.

Pat opens his maw and accepts Grant’s entire paw in his mouth. The taste is slightly salty, and he truly loves it. He sucks at the claws and groans at their pleasing hardness. Above him Grant is pumping in sadistic bliss. The simple joy of having a dominated being tend to his paws has always particularly excited him. He snarls like an animal as he shoves his paws into his pet’s face.

“Who’s my paw slut huh?” He asks sharply. He withdraws a paw to allow Pat to speak.

“Mmm, I am.” Pat says eyeing the withdrawn paw in visible disappointment.

“-You are- what?” Grant asks.

“I am, Master.” Pat says while looking sheepishly into Grant’s evil eyes.

“That’s right.” He says while shoving both paws onto Pat at once. He caresses the bat’s head with one paw while pressing his chest with the other. The feel of the squirming latex beneath his paws is the final push that he needed. He pumps some final times before blowing a huge load of cum onto Pat. The bat only stares up dumbly, mouth agape as his face is covered. Specks of white pock his face and a bit of it hangs from his chin. Grant at length finishes, leaving his pet a filthy mess. He tosses some final drops onto the dimwitted bat as he rises from the bed.

“Ohhhh yeah. That was amazi— hey!” Grant says. “Don’t wipe it off. You leave my seed right where it is, like a true slut.” Pat stops trying to whip the seed free of his face and sits grinning on the floor. Grant recovers his pants from the corner in which he’d thrown them. “Well Nuka I hate to cum and go, but master has places to be. I have another pet like you, a big monster of a skunk, who is begging for some… attention.” Pat gives him a dismayed look. “But you’ve been pretty good so I’ll give you a deal. I’ll turn you back to normal. But I will show up from time to time to change you into bat form and treat you like an object. I have a weak spot for furries, so I’ll only visit after sundown. Do you understand Pat?” The bat blinks a few times in confusion. His mental faculties are beginning to return. He does slowly understand Grant’s stipulations and nods.

“Good. Bye Pat. And hey, you’re welcome.” Grant says. A shadowy portal appears at his feet into which he rapidly descends. As soon as his portal vanishes Pat appears in his human, naked body. He has full control of himself and is fully aware of what has happened to him. His room reeks of sex and body odor and he is still covers in seed, the last clue that Grant had been there. Pat grimaces and begins to panic. Mortification is not a strong enough word to describe his mental state. Nearly in tears he grabs a towel and wipes the bulk of dog cum from his body. He wraps himself in the towel and darts from his room to the bathroom across the hall. His roommate who had seen his dismayed state calls his name, but he ignores her. He starts a hot shower immediately and drenches himself is its cleansing waters. 

“Oh god. What have I done?” He whispers. It had always been his dream to meet and potentially have sex with an anthropomorphic animal, but Grant had turned that perfect dream into a nightmarish reality.
