Three hollow "clonks" vibrated through the apartment door. The entryway cracked open with a pop as it hit the chain securing it. A green eye peered out to see a male quadrupedal horse standing in the hallway. He was white with chestnut splotches painted across his body, at least from what could be seen sticking out of his plaid jacket. He craned his head down so that his large blue eye looked back at the green one staring out at him. A long ginger braid dangled just at the edge of the door crack. It had a few strands of silver running through it.

"Sebastian!" A voice rang with joy from just behind the door. It quickly shut in the horse's face, nearly giving his eyelashes a trim. The rustle of the chain unlocking could be heard and then the door flung open just as quickly as it had shut. Standing framed in the door was a sight to behold. It was Tanit in nothing but a t-shirt and panties. This shirt had a faded logo of some band that Sebastian didn't recognize on it, at least in the spots where there weren't holes. Their blue fur poked out and hints of golden scales could be seen through these gaps. The shirt wasn't doing them many favors. It was so worn that you could basically see through it despite it being black. The bottom of it bunched up on their hips and thick tail so that their teal panties were practically on display. A smirk was planted on Tanit's face as they could see Sebastian try to hold back his fluster.

"Can I come in?" Sebastian neighed, "The guy in the lobby was giving me weird looks on the way up."

"Him? Pft. He's harmless." Tanit said dismissively. "He's just some normy that doesn't know a good time."

"Still. I'd rather not be out here more than I need to." Seb replied curtly.

"Come in! Come in!" Tanit said while moving out of the way. "You know you're welcome here." The viperbun reached underneath Sebastian and he visibly tensed up. "Easy, big boy. We're not starting yet. Just taking your jacket." They said as they popped the clip and slid it off him. Tanit let the door swing shut after Sebastian and hung his jacket up using every available hook.

As Sebastian walked farther into Tanit's place, a figure caught his eye. She had more tail than body and was wearing even less than Tanit. She sat, framed by a tiny bay window, with her legs crossed and her tail over her lap. Her eyes glowed a faint hue that slowly shifted color as she sat there. This was in sync with a long fin that started at her head and ran all the way down to the tip of her tail. It gave off a faint light that outlined her soft curvy figure. She had earbuds in and was seemingly listening to music. Sebastian could tell by the way that she tapped her fingers and by the wobble of her bare breasts as the eel lady shimmied gently to herself.

"What's she doing here?" Sebastian asked.

"Oh, that's just my coworker, Dani." Tanit chimed in with a wave. Dani gave a big smile that showed all of her pointy teeth and waved back. She didn't even take her earbuds out and just went back to not really paying attention.

"Okay, but why is she here?" Sebastian asked again.

"She's here so that last time doesn't happen again." Tanit said while gently booping that large horse nose. "It also doesn't hurt to have an extra hand when doing these transactions. Especially with how messy they can be.~" They trailed off with a giggle.

Sebastian didn't seem completely convinced by this and just replied with a little snort.

"Look, it's still the usual deal." Tanit added. "Dani's a professional. She's not going to get in our way." They curled their tail around themselves in an idle playfulness and gave Seb a smile. "Besides, having a pretty girl watch shouldn't trip up an old stud like yourself."

"Fine. Fine." Sebastian said in a huff. "At least you're not putting things in my butt."

"We can!" Tanit replied with glee.

"Nono. That won't be necessary!" Sebastian's eyes went a bit wide at that remark. "Just show me where you need me."

Tanit's smile softened as they approached his face. The serpentine bunny slid their arms under his jaw and pulled him to their chest. Tanit rested their cheek against his forehead as they smooshed his nose between their barely clothed breasts. Sebastian fidgeted his back legs while shoved in this precarious position. Tanit whispered "You're a good horse, Seb. Thanks for coming." intimately into his ear. Their hands stroked up and down the underside of his jaw as they said this. The message was clearly received with a quick ear flick.

Tanit then pulled away from his face with all but a single hand under his chin. Their fingers scritched beckoningly as they led him across the apartment. The two found their way to the middle of the room. All the furniture had been pushed against the wall and a large drop cloth was spread across the floor.

"All this for me? You shouldn't have." Sebastian said dryly.

"I'm planning ahead. I was only half joking about things getting messy." Tanit replied. "Now come on. Get in the middle there." They said while giving his ass a slap.

Sebastian glared at Tanit, but walked to the middle regardless. The cloth dampened the clop of his hooves against the floor, which hopefully made less racket to anyone below them. He was in the position they wanted. "Now what?" Seb huffed.

"Now, you relax and let me take care of you, Seb." Tanit cooed. They peeled off that worn shirt and tossed it to the side. Their perk bosom bounced as they made their way closer to the horse. The golden scales across their middle and down their tail danced in the light. The viperbun reached Sebastian's face again, but this time guided it towards their own. Tanit's scaly lips pressed against the horse's large pink muzzle. Their hands stroked all along his cheek and neck while in this embrace. A warm huff ruffled Tanit's head fluff and they glanced up to see a rather bashful stallion looking back at them.

It seemed that Tanit stole the words from Seb's lips. He was dumbstruck. The horse kept his head low and watched as his playmate made their way down his body. Their fingers ran across his coarse fur from his neck and down his flank. He could see them pop their hips with each step, but couldn't make himself look away from that sexy sway.

"You seem tense, Sebastian." Tanit cooed. "Let me..." They slide underneath him and nearly out of his sight. "...relieve you."

Sebastian jumped as he felt a pair of hands curl around his sheath. The horse relaxed into the groping with a heavy shiver. Tanit slid their palms along that sensitive skin and could feel the swelling mass within it. This caused Seb to stifle a moan. At that same moment, his thick head pushed out of the sheath. Tanit flicked their tongue into the air to get a good taste of that heavy male aroma. A few more squeezes of that plump sheath and the rest of Seb's length spilled forth and nearly touched the ground between Tanit's knees.

"Gods, you are good, Tanit" Seb huffed.

"And I've only just been using my hands, hun" Tanit cooed in response. Those scaled fingers danced down and then back up that long member. They saw it pulse and thicken with each moment of teasing. Sebastian could be heard taking heavy breaths in an attempt to hold it together. He was failing.

By this point, Seb's cock was starting to support its own weight. Tanit groaned softly to themselves at the sight. They wrapped both hands around him and stroked all the way up to the head. Drawing the blood up like that caused his tip to flare ever so softly. His girth nearly reached their shoulder and Sebastian was huffing up a storm from all the attention.

Tanit took this opportunity to sling that meat over their shoulder and get in close. Their palms traced the veins starting to bulge from his stiffening shaft, bumping over the median ring on their way down. Those serpentine fingers finally found their way to his now drawn back sheath. Tanit traced a singular dull claw tip along the inside of the sheath's opening. A visible shudder went through the stallion. They were a little disappointed at the weakness of that reaction. Tanit instead grabbed both of Seb's hanging orb and gave a strong suck to one of them. The pair were a bit too big to get into their mouth, but it definitely did the job. Seb let out a low moan and his back legs spasmed. The old stud's cock hardened so quickly that it leapt from Tanit's shoulder and slapped against his belly.

"Good boy~" Tanit sang with the biggest smile they had pressed into the soft fur of his heavy orbs. The horse felt his balls twitch again as Tanit snaked their hands around them with a gentle lift. Each firm squeeze elicited another groan from the aged stud. Within just a few moments, Tanit could feel Sebastian's desperation. His unmistakable scent filled their nose as a warm dribble of pre slid down their back. Tanit trembled for a moment as they felt a line of their bunny fluff and shiny scales sprout into coarse horse fur. "N-now we're getting somewhere." They managed through the twinge of pain and pleasure.

Tanit laid way back until they were reclined beneath Sebastian. The viperbun stroked their hands along that tense flesh. Each pull extracted a few more drips of pre onto their chest. Tanit gasped as little spots of blue roan fur grew from each drop.

They were looking down Seb's barrel and watched as he slowly flared. "F-fuck!" Sebastian nickered, "Tanit... I'm close."

Hearing this stretched the existing smile wider across Tanit's serpentine lips. "I see that, stud." They teased. "Just hold out one second longer." With one hand still wrapped around that shaft, they leaned out from under the horse to paw at a package about the size of a holiday card. Tanit ripped the top open with their teeth. They could see Sebastian's balls tensing as he fidgeted to hold back. "One more second~" Tanit sang through the package. With a bit more urgency, Tanit pulled a rather large condom out from the envelope and spit the empty shell off to the side. Sebastian's flare had spread to larger than the opening of the sleeve, so they had to stretch it past his head. The tightness caused Seb's member to start convulsing and they knew that time was pf the essence. Tanit used both hands to unroll the horse condom down as far as they could before-

Sebastian let out a loud neigh. An eruption of thick white liquid stretched the end of the rubber and swelled into a sizable balloon. Tanit could feel each shot through the pulsing underside of his cock. They purred happily to themselves and milked that length for as much as he would give. The old stud panted and huffed with each blast. The kneading kept this going for a solid minute of cumming. As Seb's orgasm slowed, his member sagged towards the ground from the hefty load hanging from it.

"Such a good stud, Sebastian." Tanit cooed while giving his belly a few pats. "What a full first load. This is perfect." They pinched the condom at his head and pulled to draw all the horse jizz into a ball at the end. This in turn tugged on Seb's sensitive shaft. He let out a few grunts and tried to lightly shake off the sensation with a shiver. Tanit slid the condom the rest of the way off, only impeded by Seb's dying flare. The viperbun quickly looped the empty rubber tail around their hand and pulled it into a knot before anything could leak out. As normal, a little cum did manage to sneak out and dripped across the back of their hand. It was very little, so there wasn't too much of a reaction, but Tanit could feel their fingers start to stiffen like they wanted to get pulled into a hoof.

"Hey, Dani." Tanit called without abandoning their post under the stallion. The call went unanswered. "Dani!" They yelled a little louder. With still no response, Tanit popped their head out to see the eel lady poking at her phone and lost in her music. Tanit threw the horse batter water balloon and pegged Dani right in the gut with it.

"Oof. What was that for?" Dani moaned while popping an earbud out.

"Oh good, you can hear me now." Tanit snarked. "Would you kindly put that cum balloon in the freezer? I've currently got my hands full with Seb here."

Dani grumbled something along the lines of "Yeah, yeah. No problem." Before picking up the bag of jizz. Tanit trusted that they could handle that simple task. So they went back to focusing on the horse above them.

Returning to the old stud's rod, Tanit was hit with a powerful wave of Seb's musk. His head still had some cum clinging to it. Pulling the condom away had let all of the trapped fluids air mere inches from Tanit's face. The smell was intoxicating. They tasted the air once again and let out a tense huff. Tanit snatched Sebastian's fading shaft with both hands and felt it slick with a residue of condom lube and cum. Their hands tingled with the mild reaction, but they slid them back and forth regardless.

"Ah! Tanit! That's still sensitive." Sebastian groaned. His balls tensed as his dick throbbed back to life.

"Come on, stud." Tanit goaded. "We've done two in a row before. I know you're good for it." They worked a few thick droplets of cum down his shaft and out onto their belly. The tingle of those speckles made them suck air through their teeth. "I need more, Seb." Tanit pressed their snoot to his head and lapped at the jizz clinging to it. They could feel the blood rushing back through his member with an unmistakable growing warmth. Their fingers tugged and kneaded at his flesh.

"F-fuck. Keep that up and you'll be getting plenty." Sebastian said with a shiver, but Tanit was off in their own world at this point. They pressed their lips to his cockhole and ever so gently mouthed it like they were kissing a lover. In no time, Seb was throbbing against Tanit. A new trickle of pre rolled from his tip across those scaly lips and down their chin. Tanit moaned at the taste and the jolt of change that bolted through their face. They were being a bit more aggressive than a handjob this time and it really got the juices flowing. Tanit's muzzle was quickly turning pink and fleshy with white fur growing out of it. There were little rubber like squeaks as their scales popped apart and faded as their nose elongated from their snub viper face into a muzzle more fitting for a mare. Their tongue, being absolutely coated, ballooned into a more mammalian shape. It filled their mouth in a way that felt heavy to them, but provided a better means to lick all across Seb's leaky head.

Being wrapped in Sebastian's smell and feeling their body twist into something more his shape was driving them mad. They could already start feeling their brain shift slightly with the bit of precum that they've swallowed. They had to. Tanit pulled a hand free from his shaft and wiped some of his stickiness from their chin. They could feel the fingers of this hand pulling together into the start of a hoof, but they shoved it down their panties regardless. The soon to be mare quickly worked his slickness into their own and felt an intense reaction immediately. There was no light tingle this time. It was like needles. Their pussy lips very quickly puffed up and stretched. The feeling was bliss. They grabbed another handful of horse juice and worked it into their loins. They rubbed it into their swollen clit and dipping their now joined fingers into their depths. Tanit could feel it in their guts as their passage deepened to accommodate equine dick. Their belly distended ever so slightly with all the new flesh that didn't yet have a place to go.

Tanit was struggling to continue to rub themselves. Pulling their hand back, the teal panties landed taught against their new bulging bits which began to soak the fabric. Tanit found that hand had formed into a hoof. That limb was now basically useless in their endeavor. No matter. They still had one good hand and a very functional mouth.

By this point, they had their jaws stretched wide, but were still unable to fit that broad head in. They needed more horse juice to fuel their changes. So they furiously stroked his length and tried to milk every trickle into their hungry maw. Tanit lapped at it greedily to the point of pressing their tongue against the opening. The slick coating of saliva and cock fluids made just the very tip slip into that wide urethra.

"Sh-shit!" Seb swore, "Too much. Too much, Tanit!" The stallion was overwhelmed by this unusual sensation, but his body gave the response that Tanit wanted. His shaft spasmed uncontrollably in their grasps and they could feel that flare stretch against their lips.

Tanit gulped down another small mouthful of pre. This swallow tingled all the way down into their chest. The front half of their face was already pushing out into that of a horse, but now their neck stretched forward and thickened. This change from their chest upwards twisted their head to almost completely equine. The only thing remaining were a set of floppy bunny ears and those piercing snake eyes.

These alterations were exactly what they were looking for. Tanit shakily braced themselves on that hoof hand and rocked forward. Their horse head was now large enough to wrap around Sebastian's dick. Tanit let out a hot huff and easily slid a third of that horse cock into their muzzle. They paused for a moment as that flare sat at the back of their throat. It's shear size was daunting to this fresh mare mouth. Tanit worked up to it by pulling away and sliding back to this point. They were hoping that this would also be a catalyst for further growth so that they could greedily swallow as much of him as they could like a good mare. Each pass felt easier. And each pass they could feel Seb twitch.

"Gods, that feels amazing." Seb moaned out. "I'm... I'm not usually lucky enough to fit in someone's mouth." Tanit curled their muzzle into a grin around his meat and snorted some hot air against his belly. That moaning was just the encouragement they needed. This time when Seb's flare slide to the back of their muzzle, Tanit leaned forward into it and felt it slip right down their throat. They let out a muffle moan at that stretched feeling. It felt so big that they swore that you must have been able to see it bulging their neck out.

Tanit took it further though. Now that he was in their gullet, they pushed farther and swallowed almost three quarters of that monstrous length. Not many can say that they've deep throated a horse, but Tanit was now one of them. They worked him in and out. His spasms were coming quickly. He was trying so hard to hold back, but Tanit wanted none of that. They wanted their fill now. The horse in progress pushed as much of that cock into their mouth as they could and held it there. Then with their working hand, they grabbed the dangling orbs in front of them. A huge wave rippled through Seb's member that Tanit could feel in their stomach. This pushed Sebastian over the edge. His composure broke with a groan. He could no longer control his urges and began humping Tanits face. It only took a few strong thrusts into them before he was cumming once again.

There was no rubber to hold back the flood this time. A surge of sticky fluid blasted its way into Tanit's stomach. So much so that it started coming back out of Tanit's mouth. They tried to swallow as much as possible, but was resigned to pull away from that horsecock. Seb's head popped free while still cumming and covered Tanit's face in a hot gooey mess. He continued to shoot rope after rope of thick horse batter all down Tanit's front. Sebastian quivered and panted in time with his climax.

Sebastian was only out done by Tanit's loud moaning. They were writhing on the floor as the changes took their body. Their middle began to cramp up as the large amount of cum that they gulped down got to work. A fire filled their chest that they knew was their insides rearranging themselves. This burning even made its way to their brain. A deep haze clouded their mind as their odd combination of bunny-viper instincts began to be overwritten by horse instincts. The scent of Sebastian started out as only needy male musk, but there was suddenly more to it. A keyhole had taken shape in their brain that matched the chemical key that Tanit had huffed from this stud. It unlocked a deeper primal urge that was not there before.

At the same time, their bunny fluff and snake scales were quickly shedding away for short horse fur of blue roan smattered across white. Those long ears of theirs shrunk and pulled themselves upright into perk horse ears from all the cum that was dripping off them. Tanit wiped the cum from their eyes to reveal that they had become large and round, but remained the same piercing green color. Tanit's top half was rapidly morphing. The heavy dose of jizz saw to that. Each arm began to lengthen with sickening cracks while their muscles torqued beneath the skin. Their shoulders broadened and their chest deepened bringing with it the feeling of their breasts descending and hugging closer to their body.

So much was happening at once that Tanit's mind was pushed further into the fog of bliss and transitory discomfort. It was beginning to get harder to move in a manner that they were used to. Tendons and muscles were shifting inside them like a fluid, but they kept trying to pleasure themselves regardless. The one hand that hadn't completely changed yet shot down to rub Seb's gifted slickness into their needy hole. This was very short lived as the massive amounts of cum had turned this hand into a hoof as well, robbing them of the dexterity to navigate those tight panties.

The horse's fluids continued to run down Tanit's body leaving streams of horse fur that cut into the landscape of scaled plains and downy hills. They awkwardly craned their arms to wipe Seb's fluid down their body, but their joints didn't quite rotate the same way as they did before. It was taking a monumental effort, but they were able to shimmy more of it down. Additional rivulets of jism rolled down their tail. Where it should have been leaving trails of blue fur, instead the paths seemed to compress in on themselves. Each drop was making Tanit's tail smaller and smaller.

"That... that ought to do it." Tanit mumbled to themselves in a horse voice. At this point, the large amount of fluid they guzzled was beginning to drive their body's changes. They could feel it flow through them like magma in their veins. They ached as their bones stretched and their muscles torqued, but this also made them ache with desire. Two final pops set their shoulders in place and now they weren't even able to reach themselves to toy if they wanted to. What was in reach, however, was Seb's juicy leaking meat. Tanit leaned forward and landed on their shaky new hooves. Their lower half was too small to support their hulking horse torso, so they had to just kick it out to the side in the meanwhile. With that long equine neck, Tanit stretched their head forward and reached out their tongue to grab at that sagging tip. They pulled it into their mouth to lap up every last iron twinged drop.

Sebastian cringed at the continued suckling. "Ah. Too much! No more, Tanit." He whinnied. His dick didn't come back to life this time, but instead continued to deflate slowly. Tanit was successful at drawing out a little more seed from him however.

They continued to mouth at his head as they looked for more. Their body filled out down their lower half. Their waist expanded out into a solid core. Their breasts continued to slide further down their body until they reached their belly. They had become nearly flat to the skin at this point. Their lower spine stretched and untwisted itself to proportions more fitting of a mare. Their transformation then went to work on their hips. They became more defined and boney which stretched their underwear to its limit. The muscle that followed gave the final push that popped the seams of that thin fabric and left it in tatters on the floor. Their tail that had been slowly shrinking now quickly collapsed in on itself until it was only a foot or so long. At the same time, long blue hair sprouted from it into a luxurious horse tail.

The changes began to slow. The last big movement was their legs contorting to rotate beneath them. Tanit's haunches popped into place and their legs began to extend into spindly horse limbs. Their toes stretched and formed together. They hardened into hooves. Tanit found themselves sitting on their butt with their back legs sticking way out. The fire burning inside them was dying down. The last of their chiseled horse muscles filled into their back half.

Tanit dropped the flaccid horsecock from their muzzle. They panted as the exhaustion of this ordeal finally caught up to them. They lifted their head and gave Sebastian a few knocks on his side. "Give me a little space. I don't want to knock you over." Tanit huffed out. Seb stepped to the side and then turned to see Tanit in their new form.

Starting at an awkward position for a horse, they managed to get their back hooves under themselves. Tanit stood there shaking on fresh legs. Before him stood a blue roan and white painted mare. Their long mane flowed down their neck and over their shoulder. They gave their tail a flick and their back legs a stomp to loosen a few stray gobs of horse seed. Sebastian was dumbfounded.

"You...you look incredible." He stammered out. "I know we've done this before, but the sight of you like this just never gets old."

Tanit smiled with their bright green eyes. They then stepped over to him and curled their neck around his in a sort of hug. "Thank you, old man." They nickered. Tanit looked about to see the sticky white puddles around them. "You really did a number on me. Good thing we had these sheets down." A sly smile crossed their muzzle. "At least we know you're still potent. I wouldn't have changed so fast if you weren't." They teased.

Sebastian seemed to have blushed at this. He was perfectly capable of shrugging it off from Tanit's viperbun form, but put a mare before him and he melts into putty. "Oh stop. You did all the work." He huffed.

"Look at you two lovebirds. Haven't you done enough fucking for one night?" Dani piped up. She was leaning against the doorway into the kitchen with a nonplussed look on her face. "We still need to clean all this up."

"Right. Right! Sorry, Dani." Tanit neighed and trotted over to her. "Get my wallet so I can pay the man." They peered over their shoulder to see Sebastian staring. So they lifted their tail to show off their puffy mare bits. "Unless you'd rather fuck this fresh new pussy as payment." Tanit gave a final tease.

"The money is fine." He said with a huff. "Don't think I could fuck you if I tried right now." Seb flexed his groin to make sure he really wasn't up for more. His body's subdued response told him everything.

Tanit tutted. "Poor stud. Suit yourself." At this point Dani came back with Tanit's wallet and spread it open. Tanit shoved their huge muzzle into it and pulled out a wad of paper money with their teeth. They deposited it into a pocket in his coat and awkwardly picked it up off the hook. They tried to get it on Sebastian, but Danissus had to lend a hand to get it all the way on and secured. "You are all set, sir. Three hundred dollars for the two loads. Our usual arrangement."

"Thank you, Tanit." Sebastian nickered. "And thank you for the help, Dani. It was a pleasure to meet you." Dani quickly unlocked the door and opened it for Seb before Tanit even could try with their horse lips. And in a moment, their guest was gone.

"Well. How do I look, Dani?" Tanit said with a whip of their mane.

Dani came back zippily, "Looks like you could use a bath."
