Taro approached the injured foal slowly, kneeling down and keeping his empty hands in clear view. He moved slowly, moving one foot at a time, ignoring the way his legs were protesting his squatting approach.

“Shh... easy, easy...” Taro whispered gently to the foal. “I’m not going to hurt you. I promise.”

The little foal whimpered, trying to stand and flee, only to collapse as it put too much weight on its wounded leg. Taro paused and waited as this happened, before starting to move closer once more. 

“Easy, Ponyta... I swear on my life, I will not hurt you.”

The little Ponyta was still very clearly afraid of him, but didn’t try to move again. Taro slowly removed his backpack, keeping his eyes on Ponyta’s at all times. Ponyta’s blue mane began to flicker further, spewing embers out and onto the grass at the human’s movements. Taro could tell that he was being watched closely, and so he slowly opened his pack and removed his first aid kit.

“Alright, Ponyta, I’ve got a potion and some bandages here,” he explained calmly. “I’m going to spray your knee with the potion to help it heal. It’s going to sting a bit, but then I’m going to put the bandages on. But to do that, I need you to straighten out your leg.”

Ponyta tensed a bit, but slowly straightened out her wounded leg, keeping a close eye on the human. Taro stepped closer, and very gently took a hold of her left foreleg. Ponyta flinched and whimpered when the potion was sprayed onto the great cut in her leg. Shortly after, numbness set in, and Ponyta sighed as the pain from the wound left her. She watched closely as the human gently wrapped bandages around her leg, all the way from her fetlock to her knee.

Ponyta watched as this human, unlike the other that had so cruelly cut her leg and abandoned her, tended to her wound, almost like her mother would have. Ponyta whimpered again, the memories of her mother being taken from her by that cruel human brought tears to her eyes once again. Fighting them back, she looked to see that this new human was just finishing putting on the bandage and was now cleaning the area around the wound.

Taro smiled gently to Ponyta. “There, that’s much better, isn’t it?” Ponyta gave him a weak smile and nodded. “But you aren’t anywhere near your herd, are you?”

Ponyta’s weak smile faded, and she shook her head. Looking over in the direction that they had fled, she knew it was far too late to follow them at this point.

“Well, listen, I live near here,” Taro began. “I have a Zebstrika with me. Would you like to come stay with us while you recover? Afterwards, we can help you find your herd.”

Ponyta thought about it for a few moments, weighing the pros against the cons. On the one hoof, he had helped and treated her wound; he was kind and gentle, and it was clear that he cared. On the other hand, he was a human, and the longer she stayed with him, the more likely it was that she’d be gone from her herd forever. But with a Zebstrika, it was possible that she could find her herd again fairly quickly.

Sighing as she resigned herself to her decision, she nodded towards the human that had so kindly helped her.

Taro smiled, “Alright, follow me as best you can.”

Ponyta very carefully followed the kind human as he led the way. He took his time, letting her keep up with him easily. When at last they arrived at his place, the first thing that Ponyta saw was the Zebstrika that Taro had mentioned. He was big. Bigger than most Zebstrika that she’d seen, and it somewhat intimidated her. He noticed the two of them approaching and came over to the fence at a leisurely pace. Taro smiled and approached his old friend, smiling wider as the electric zebra craned his neck over the fence and placed his forehead flush against his human’s.

“Welcome home, old friend,” Zebstrika greeted in his native tongue.

Taro gently stroked the stallion’s neck. “It’s good to be home again, Striker. I brought a friend with me this time.”

Striker chuckled, peeling away from Taro to look over the young mare. “I can see that. Come forward little one, I will not harm you.”

Ponyta felt her ears pin back against her skull as she hobbled towards the large stallion. “H-Hello, sir.” She bowed her head submissively as she came close.

Striker chuckled again at the young mare, before he gently leaned down and nuzzled against her neck. “You don’t need to be afraid. I give you my word that I shall not harm you.”

Ponyta tensed when Striker began to nuzzle against her neck, but soon relaxed. It reminded her of what her mother would do to calm her down. Striker stopped after a short time. He backed up, but just enough to lean down and inspect her bandages through the fence. He glanced up at Taro, recognizing the scent on the bandages. 

“I found her wounded on my hike,” Taro explained. “She’s gonna stay with us for a bit to heal, then we’re going to help her find her herd.”

Striker nodded and headed on over to the gate, where Taro met him and opened the gate for Ponyta. She took her time stumbling through, but neither of the males were in any hurry anyway. As soon as she was on the other side of the fence, Striker moved to her side and gave her some support to make it easier on her leg. Giving the stallion a grateful look, she accepted his help and watched as Taro went ahead and made sure the stalls were clean and stocked with food and water. Striker rolled his eyes and leaned in close to Ponyta as his trainer did so.

“He’s always wasting time worrying about how I’m doing,” Striker commented quietly. “It makes me wonder if he even has other hobbies.”

Ponyta couldn’t help but chuckle. “I know the type.”

“How about you? Do you have someone like that?”

Ponyta nodded, her ears pinned back again. “Back with my herd.”

Striker nuzzled against her cheek, making her smile. “We’ll find them, little one. I promise.” 

“Thank you.”

Striker smiled at her, gently helping her into the empty stall next to his. His ears pinned back for just a second as a memory came to mind, something that Ponyta missed since she was still getting comfortable.

Taro, however, did not miss it, and whispered, “Sorry, bud. It’s the only other stall we have, after all.”

Striker nodded slightly. Ponyta looked interested about what they were saying, but was polite enough to not ask. Instead she focused on making herself comfortable in the small stable. Taro came over and helped her lay down. Once she was, he set to making sure the bandaged leg was all set. 

“I’ll have to go to the town to get a doctor. I’m good at handling these, but I want to get a professional’s opinion.”

Ponyta licked her lips a little. Another human? Only when Striker gave her an encouraging nod did she agree to it. Taro stood, went over to Striker and whispered for a bit; as the human left, Striker moved over into Ponyta’s stall and carefully settled in next to her.

“He said he’s getting a... professional?”

Striker nodded. “Some humans have more knowledge than others. Like how some Pokemon have more training than others.”

Ponyta slowly nodded. “Okay... I think I get it. So he’s... going to bring them here... to make sure I’m okay?”

“That’s right.”

Silence fell across them. Ponyta shuffled in place a bit, wincing when pain thundered through her leg. Striker moved to help. He had to retreat when he found that he was not yet trusted enough to touch her. He took a moment to wave off the heat. 

“So... what’s your herd like?”

Ponyta was smiling before she realized it. Not that she really minded it. “It’s small, but... safe. Really safe. Our leader is really, really strong.”

“I’m back!” Taro called. “I brought Nurse Joy with me.”

Joy stepped into the small shed, Chansey right behind her. “Hello, Ponyta. I know you’re likely scared, but I’m here to help make sure your wound will heal properly.”

Ponyta glanced at Striker. When the older stallion nodded, Ponyta swallowed and nodded her consent to the human nurse. Chansey stepped in first, carrying a small box.

Chansey spoke, “These are items we use to help make sure you’re alright, Ponyta. I can explain them if you like!”

Ponyta nodded. While Chansey spoke, pointing at each one, and explaining what Nurse Joy did, Taro headed back inside to get some food ready.

When he finished and brought the food out, Joy explained that the wound was relatively minor, but would take a few days of rest and light activity to heal first. She promised to return in three days to ensure that Ponyta was recovering properly.

So naturally, two days later, Taro returned from a day of running errands to find Striker trotting around the paddock with Ponyta. Taro rolled his eyes.

“Striker!” Taro cried. “Joy said rest, not races!”

Striker slowed down just enough to stick his tongue out at Taro, then caught up with Ponyta and nickered some laughter as she giggled and dodged to the side. Taro rolled his eyes again and headed on inside.

“If Nurse Joy gets upset, I’m throwing her at you Striker!”

Striker very nearly skidded into the fence in his panic to stop. “What?! Taro -”

“Nope, you make her wounds worse, you deal with the fallout,” Taro told him firmly. “Now get your fat ass over here for food.”

Striker grumbled even as he slowly walked over to the feeding trough. Ponyta unrepentantly snickered as she followed. Striker smiled and shoved her lightly with his shoulder.

“Glad you’ve gotten comfortable,” Taro said to her softly. Ponyta nickered quietly and gave soft happy noises as Taro gently scratched under her chin. “I’m going to be super busy the rest of today and pretty much all of tomorrow. I’ll make sure food and everything is all set, but try not to break anything this time, Striker?”

The Zebstrika gave Taro some side-eye and resumed eating. Taro chuckled and headed back into the main house. As he did, he passed a few photos and sighed softly. Taro looked over the various photos of him and his girlfriend, hoping she would take some time out of her busy globetrotting job to visit more often.

The woman, half a head shorter than Taro himself, and modestly proportioned was someone that he’s been going steady with for the better part of a decade at this point. They met by accident during some rescue work, he’d asked her out the next night at the post-successful rescue party, and it went from there.

Taro’s mind wandered to a small box he had hidden in one of his bedside tables, then shook his head to clear his mind and resumed starting up his chores.

Over the next couple of days, Ponyta wound up finding herself relaxing far more than she’d expected. Striker carefully, lovingly groomed her coat. He also stubbornly refused to race her.

When Nurse Joy came over the third day, when Taro was also present, Ponyta somewhat understood. The woman was reasonably polite and kind, but it was also clear that she was tired. Chansey also heard from Ponyta that she and Striker did a bit of a jog two days before, and Ponyta clearly saw her friend’s life flash before his eyes.

Chansey just stared Striker in the eyes. Striker did his best not to sweat or twitch or move; he knew just how easily a Chansey could sense fear.

Taro just took a photo. Striker made a mental note to trip his trainer onto his ass later for the betrayal.

Nurse Joy stood after a few minutes. “The wound is clean and is healing fine. I’ll still ask that you keep the physical activity light for another couple days.”

Ponyta nodded. Joy smiled and turned to Taro. “And thank you for the tea. It was fantastic.”

“You’re welcome, Nurse Joy,” he said. “Have a good rest of your day.”

Joy just nodded and finished packing up her supplies, heading out of the stable with Chansey behind her. Striker swallowed as Chansey glared at Striker before they left.

Taro snickered. “I think I’m going to get this photo printed and framed.”

Striker snapped his attention to his trainer. “What! Taro!”

Taro laughed and vanished inside the house.

Striker huffed and stamped his front hooves. “I’m gonna make him sorry for that.”

Ponyta snickered. Striker blushed a bit even as he smiled. He opened his mouth -- then cut it off as a very familiar scent reached his nostrils. He froze and turned towards the edge of the ranch.

“...Striker?” Ponyta called after him.

Striker didn’t hear her. He was too focused on sniffing and checking the scent. He called out softly, “Love? Is... is that you?”

Inside, Taro was in the middle of setting up his camera to download the new photo to his computer when he heard his starter call out enthusiastically, shortly followed by what was undoubtedly Striker leaping over the fence.

It was a rather familiar sound.

Taro groaned and sighed, rubbing his face with his hand. Admittedly, they lived pretty far from the rest of town -- a several minute drive on a sunny day, when the dirt road was dry -- but that just made finding and bringing Striker back an even bigger hassle.

Taro stood from his desk and made it only a few steps before he heard the doorbell ring.

He sighed a bit and headed over and opened his front door.

Before he could get even one word out, however, whoever it was gasped and latched onto him, kissing him.

Taro instantly recognized the taste of the other’s lipstick and the soft, forest pine scent of his girlfriend.

He picked her up and kissed her back.

They absentmindedly shuffled into the entryway of his house, kicking the door shut behind them. Taro pinned his lover to the wall, absolutely adoring the way she moaned as he started nibbling on her exposed collarbone.

It took several long, wonderful moments for Taro and his lover to stop making out.

She panted softly into his face, a breathless grin on her face. “Taro...” she paused as he started slowly removing her shirt. “Mnf, fuck I missed you, Taro.”

Taro chuckled. “I missed you too, Xen. Dyed your hair again?”

“Mm, not this time,” Xen said. She giggled softly when his hand brushed against her side, her spaghetti-strap shirt easily slipping off her chest.

Taro raised an eyebrow. “Really? The rainbow tips and the blond isn’t dye?”

“Nope.” Xen grinned and brought his face in closer for another kiss. “Now bring me to the couch and rut me, it’s been way too long since we’ve fucked.”

“No thanks,” Taro said. He adjusted his grip on her tight, yet palm-overflowing ass just enough to lower her shorts and -- “Mm, you really are needy, no panties today?”

“Too excited,” Xen admitted. She moaned quietly when Taro’s thumb brushed her wet vagina. She kicked out her legs to the side, wiggling her shorts out of the way. She did this while simultaneously using a hand to shove Taro’s own shorts and boxers out of the way, revealing his gorgeous erection. “Take me, Taro. Take me and fuck me, my love.”

Taro leaned his head forward and clamped his teeth around Xen’s exposed collarbone, enjoying the thrilling shiver that raced down his spine as she moaned into his ear. He didn’t hesitate any longer - he wanted this just as much as Xen did, after all.

He lowered her onto his erection - slowly, ever so slowly filling her with himself. Their moans echoed slightly in the entryway as both Xen and Taro enjoyed the sensations. Xen groaned as her lover leaned down slightly to start nibbling on her neck and collarbone.

“Nng- Taro-”

Xen gasped and cut off her word as he thrust particularly hard into her eagerly waiting and wanting vagina. He lifted her slightly off himself and thrust right back in, his jaw clenching tightly on her skin as he did so. 

It had been months since Xen had last been able to enjoy physical interaction with her boyfriend. 

Taro wasn’t much better off; just being around his girlfriend - his incessantly horny, needy, gorgeous girlfriend - after so many weeks of being alone was more than enough to get him erect and in the mood.

He focused on the act, pulling away from her, careful to not break the wall he was holding her up against as he thrust back in. He took his teeth and mouth off her collarbone, leaning a bit up as he did another lift-and-thrust into Xen’s tight pussy.

Xen gasped loudly when Taro bit into the side of her neck, suckling a tad. “Fuck - yes, fuck, mark me!”

Taro chuckled softly into the skin around her neck. “You’re always begging to be marked, Xen. Nng - damn you’re tight!”

And she was. Taro grunted and groaned as Xen squeezed her ab muscles, pressing her walls all in on his cock as much as she could.

Given how long they’d been apart, neither of them lasted long. It took Taro only a couple more thrusts - during which he continuously groped her ass and left hickies on her neck and collarbone - before they both let loose.

It didn’t help that Xen kept squeezing Taro’s dick with her vaginal walls.

“Taro, I-I’m -”

Xen was silenced when Taro mashed his lips against hers, the both of them groaning and moaning very softly as they wrestled tongues. 

A solid minute later, Xen pulled back from the kiss, panting out, “You were more pent up than I thought, your cum’s dripping out of my pussy.”

Taro chuckled breathlessly. “It happens when my girlfriend’s even needier than I am.”

“You’re damn right I’m needy,” Xen admitted openly. She leaned down and kissed his forehead. “Now, Taro -  shall we move to the couch?”

Taro took a moment to catch his breath. “Going to need to let you down to do that.”

“Mm, that’s fine, my love,” Xen murmured as she nuzzled against his hair. 

Taro very gently, carefully removed himself from her, then lowered her onto her feet. Xen giggled a bit as she had to hold on to him for balance, the very vigorous sex having turned her human legs to jelly. She took a moment to kick off her sandals, tossing the shorts that still clung to her ankles off to the side along with her top. Taro smirked at her and took a moment to slowly strip himself of his clothes. Xen bit her lip as she walked over to the couch, watching her man’s body get more exposed with every second.

“Fuck you’re hot, babe,” Xen breathed out. 

Taro smirked. He blatantly traced over Xen’s naked body with his eyes as he said, “You’re just as sexy, Xen.”

Xen stepped over to the couch and sat on the arm, biting her lip as her lover strut forward. She visually tracked his body, the lack of body fat and the well-defined muscles from all the farm work and training with his Pokemon. Xen giggled a bit as Taro wrapped his arms around her, leaning in and kissing her. She placed her arms around his neck and held him close.

She put a hand to his chest and pulled back when he started leaning forward to try and get her on her back on the couch. “Not yet, love. Lay on your back for me.”

Taro didn’t say anything, he just stole another kiss and walked around her to do as she requested. The couch was large enough to easily lay on it without his head or feet touching either armrest. Xen turned and walked over next to him, licking her lips greedily - hungrily as she teasingly traced her fingers up his legs. Taro shivered and felt his breath quicken a bit as her hand teased his penis some, coaxing it back towards erect.

Even after such a recent climax, just being with Xen was more than enough to get Taro’s blood flowing again and to keep his penis near-painfully erect. Ever since they started going steady, Taro had found that his ability to recuperate from a bout of rigorous sex had steadily improved, requiring less and less time each year. 

Not that he minded, of course.

“Taro, do you trust me?”

Taro frowned up at her. “Of course I do.”

“No, Taro,” Xen said. She moved onto him, straddling his waist. She leaned over, getting in close. “Look me in the eyes and say it. Do you trust me?”

Taro’s expression just grew further bewildered. He stared into her deep blue eyes. “I trust you, Xen.”

Xen stared into his eyes for a long moment. Then - “Good. Close your eyes. I’ll let you know when to open them.”

Taro did as she asked. He waited patiently, listening closely. He chuckled softly as he heard Xen groan and moan above him.

“Oh shush.”

Taro grinned, eyes remaining shut. “Not a chance.”

“Oh really?” Xen asked. The sly, confident tone in her really caught Taro’s attention. She whispered, just barely loud enough to be heard, “Let’s see if that’s true. Open your eyes, my love.”

Taro opened his eyes. A gasp involuntarily left his throat as he stared.

Straddling his waist was some humanoid form of a Pokémon that Taro recognized as Xerneas.

Given that Taro hadn’t felt Xen move from where she’d been laying on top of him, he could only assume --

“Heh,” the Xerneas giggled softly. Her large, bountiful breasts shook ever so slightly as she did so. “Told you that you’d hush.”

Taro blinked. He slowly slid his hands up the sides of the Xerneas’ body, her soft, velvety fur feeling absolutely divine between his fingers. He was very pleasantly rewarded with soft gasps as he did so, and even softer moans from her as he barely brushed the sides of her extra-large tits. 

The sounds alone --

“Xen?”

The Xerneas giggled again. She laid her hands on Taro’s and leaned forward slightly, to more easily look him in the eyes.“Yes. It’s me, love.”

Taro chuckled breathlessly. He traced his hands up to the side of her muzzle, staring into her ocean-blue eyes and admiring the way her horns glowed softly over the both of them. Xen smiled at him.

She asked, voice barely more than a whisper, “What do you think?”

Taro immediately pulled her face in close and smashed her lips against his own. Xen gasped in shock at the roughness. Her surprise very rapidly morphed into more soft, muffled groans as Taro shoved his tongue into her mouth, wrestling hers roughly.

Xen had to firmly pull away when she felt herself growing short of breath. She still lay against her beloved, panting directly into his face and admiring the way he stared right into her eyes.

The sheer love and passion that she could see in them -- let alone what she could smell -- 

“I don’t care what form you have,” Taro murmured. “I still love you.” He paused a bit, a sly smirk gracing his face.

Xen gave a sharp yelp! as one of his hands slapped her ass.

“Though all the extra size is very much appreciated,” he teased. She bit her lip a bit as he started kneading her plump rump. “Are you sure you need all this on you, hm?”

Xen huffed a bit. She pushed against him and sat back up, making sure to pin him by setting her extra-large ass on his waist. “I will have you know, you absolute brat --”

“Oh, I’m the brat --”

“Yes you damn well are, you little shit. I will have you know, that this is natural for me in this form.”

Taro took note of that statement, and the way she was sitting up. She wagged her thin eyebrows a bit and stuck her tongue out as she moved her hands to her collarbone, where the blue collar-like flair poked up and back. In Taro’s humble opinion it wonderfully framed her blue-furred head, the pale-yellow lines that traced her face and lead up to the antlers decorated with gems of various colors.

The antlers pointed up for only a handful of inches, smoothly curling the rest down her back, like extra-large glowing braids. Taro vaguely recalled -- from years ago -- of a very bad sketch of the antlers being big and upward-reaching.

Xen chuckled a bit, “It saves on space. Especially useful indoors. I can change them, but I rarely do.” Then she slowly dragged her hands down her breasts, gasping softly as she did.

“Those are bigger than they were,” Taro cheerfully noted. He reached up -- and found he had to sit up to be able to join her in groping her tits.

“Mhm,” Xen hummed proudly. “Just like the rest of me. Human-me is... I think like five-foot-eight? Bipedal-me is seven-foot-eight. Normal-me is nine-foot-something.”

“Would explain why you’re like two feet taller than me right now.”

Xen grinned. “You love it.”

“Yeah,” Taro agreed immediately. He peered up past her breasts and into her eyes. “Yeah, I do.”

Xen blushed. After a couple seconds, she continued, “My boobies --”

Taro snorted a bit.

Xen rolled her eyes. “Shush. My boobies go from C-cup, to borderline F-cup and bigger nipples. Because I love my boobies being large and sensitive. And thankfully, because of Arceus' blessing, I don't ever have to worry about my back or front ever hurting or being sore from the weight.”

The moment she said so, Xen found herself gasping as Taro started massaging her tits. The action only turned her on further given that he was doing so by directing her hands.

“Mmm, you’re right,” he murmured softly. “They’re extra sensitive. Are they extra full, too?”

“MMnng...” Xen had to gently pull both their hands away from her bust. She intertwined their fingers and held their hands close to her belly. “Y-Yes.”

She turned her black-furred hands over to show off splashes of milk on the palms. To prove her point, there was a trickle of breastmilk that leaked from her mammary glands.

“I adore being full of milk. So I try to make sure that I am.”

“Oh, is that why we have a chest fridge of just that? Not just because you’re ‘naturally more productive’?”

Xen giggled. “Yes. That is true, too -- I am naturally more productive. And considering who I am, there’s a bunch of extra good stuff to it.”

“Like what?” Taro asked.

“Well,” Xen smiled. “I could explain. Or I could show you.”

“I’d love to see it.”

“Then look me in the eyes, my love.”

Taro did so immediately.

Xen placed her hands on his face, softly stroking her thumb over his face. She had been considering doing this with him for a long time. Xerneas -- Xen as she has come to be known, a name she’d given with half-assed effort when she and Taro had first met. A nickname to give for a simple night to forget a month later.

And now here she was, nearly eight years later, together with the same human -- and about to ask the kind of question that had taken several weeks of arguing and debate to convince Arceus to allow. Only to find that Arcues had granted the desire to other legendaries, and simply wished to know Xen’s level of devotion.

Her love and devotion and sheer adoration for Taro -- “I want to declare you, officially, as my mate, Taro. For now and forever.”

“Your mate? Xen, I --”

“Shh.” Xen placed a finger over his mouth. “This is very important to understand, Taro. If you accept, you will not be truly human ever again.”

Taro pulled Xen’s finger away and held her face. “I know. I figured. You wouldn’t be taking this so seriously otherwise. My answer is the same Xen -- yes. Yes, I will be your mate.”

Xen knew -- she just knew from the way that he was staring into her eyes, the sensation of her powers humming and ringing every word he spoke as pure truth. So Xen smashed her face to Taro’s, mashing their lips back together and roughly shoving her tongue into his mouth. From the way he held her face -- the way she held his -- how he returned the favor and they both moaned as their tongues wrestled and explored each other’s mouths so desperately.

From all of that, Xen simply knew deep in her heart and soul just how much, how desperately, they both wanted this. 

Xen allowed her horns to straighten up to their proper height and scale, their true radiance.

As they began to glow, Xen pulled back. “I’m going to change you, Taro. You will become a Pokémon. Of what kind, I do not know - I am allowing that to be a surprise to us both. I will place only one rule on your new form.” Xen paused long enough to shift backwards, to let Taro’s still-erect penis press against her lower body. With her increased height, it barely reached halfway up to her belly button. She took a moment to push him back laying down. “You’ll have a mighty horsedick -- and I want it to be big.”

Through his groans and moans, Taro huffed around a big grin, “Yeah? How big?”

Xen hummed a bit and didn't answer, opting to keep that to herself. She took a deep breath, closed her eyes. The glow of her horns grew brighter and brighter -- and when she opened her eyes again, they, too, bore that same glow. Taro gasped slightly as it rapidly faded from her eyes and horns -- only to feel a presence pour into his body as that very same rainbow gleam shined through his flesh.

His breathless gasp turned into a strangled groan as that very same surge of power started focusing on his dick. Taro went to sit up --

“Ah-ah, my dear,” Xen murmured. She firmly pressed down on his chest again. By this point her horns were back to curling down her back. “No looking.”

“Xen you fucking tease,” Taro accused. Despite his protests, he lay back and shut his eyes. “Hey-!”

Xen giggled a bit as she finished tying one of their clothes around his eyes. He wasn't sure when or how she'd snagged it. “Just making sure, love. You love when I blindfold you, anyway.”

Taro may have been temporarily blinded, but he was still able to reach up and slap her ass in return. The squeal that Xen belted out was very much worth it. 

“And you love it when I smack your thick ass,” Taro murmured with a wide grin.

Xen huffed, which rapidly shifted into a very interested-sounding coo. “It’s starting...”

Taro felt it at the same time she said it. His breath quickened, his heart thumped heavily in his chest, and his penis seemed almost painfully erect. He felt his very blood pumping down to his crotch with ever growing force and power -- and it felt good.

“Mmmff... I can already tell your dick’s going to be fantastically fat...”

“Heh...” Taro puffed out. “You -- nnnggh -- you’re going to basically worship my dick now...”

“Ha, as if I didn’t already.”

Taro meant to chuckle, but it cut off into another breathless, almost desperate groan. Xen bit her lip as she leaned back a bit, just enough to peek past her tits and observe. The first thing that happened was that the rainbow light finally faded away from Taro’s flesh, seeming to almost sink inward. An instant later, she could see the inside of his nuts as they flashed a bright rainbow color -- and then Taro gasped as his penis spurted out a lot of colored cum. 

“GUUhhh... X-Xen, what --”

Taro cut himself off when another load of semen shot out. Xen moaned softly as the very warm cum coated her fur, even managing to reach the very bottom of her tits.

“Your balls are changing,” she murmured. “And everything inside, too. Can’t have a proper equine cock if your body can’t handle it, hm?”

“Heh, ma-makes sense,” Taro agreed. “Nnggh...”

Xen watched as his penis throbbed, pulsed with a radiant light that thundered through its veins -- and it surged up several inches, gaining mass all around in the process.

She couldn’t help herself.

Taro felt his heart and lungs nearly stutter when he suddenly found himself buried balls-deep inside Xen’s cunt. As if in response, his jewels nearly doubled in size, slightly straining their fleshy pouch.

Xen lost herself in the sensations. She leaned her head back and allowed her tongue to loll out, one hand roughly groping one of her massive tits. 

“Fuuuucckkk...” Taro groaned out, low and clearly begging for more. “Ah--!”

Taro involuntarily attempted to thrust upwards, but the sheer weight of Xen on him prevented him from moving more than a couple centimeters. He did so due to his dick surging upwards and outwards, giving the sensation of thrusting without actually doing so.

“Nng...” Xen moaned softly. “Arceus, Taro, please do that agaaIIINN!”

Taro wished he could see what was happening -- but instead he was stuck attempting to catch his breath as his penis grew once more. This time, however, it throbbed, gushed out a remarkably large (for Taro) glob of cum and precum, and pressed outwards instead of up. For a very short moment, Taro could distinctly make out many of the different muscles that Xen was using to squeeze, to caress, and to desperately milk his cock.

The sensation faded almost immediately, but Taro still found himself panting out, “Hff... Xen... damn, you’re desperate for this, huh?”

“I’ve been literally dreaming of this for weeks,” Xen admitted immediately. “Taro, you -- I love and adore you.” She paused just long enough to lean forward and rest on him. “I have been wanting to be your mate, to claim you as mine, for many, many months. So yes, Taro -- I am extremely desperate.”

Taro felt his face flush, and he knew it wasn't his steadily rising temperature. He smiled. Despite being blindfolded, he still managed to migrate his hands to Xen's face, and used that to bring their lips together. 

The soft kiss was wonderful. Rather than their usual tongue-wrestling lustful make out, they spent several quiet moments just holding each other.

It was interrupted when Taro's penis pulsed with heat and blood, growing upwards and reaching ever closer to Xen's limit.

The instant that happened, Taro shoved his tongue into his lover's muzzle. She groaned at the sheer desperation and desire of the act, surrendering fully to him. As their passionate caress continued, Taro felt his nose flattening and pushing forward, dragging his mouth along with it.

Given that Xen tightened her grip on him slightly, she clearly noticed. Clearly the advancing transformation was of great interest to her. Taro slowly lost control of the tongue-on-tongue fight, distracted by the sensations flooding his head and face, not to mention his crotch and groin.

Taro's mouth reverberated slightly as he and his mate -- his mate! -- mutually moaned and groaned and made other similar noises.

It helped that his mouth was now twice as spacious as before.

They made these sounds when his cock decided, seemingly of its own accord, to fill Xen almost completely in one swift growth.

They had both very distinctly felt as his manhood had grown several inches in length, and at least another inch in sheer girth.

Seemingly out of instinct -- or perhaps out of sheer need for movement -- Xen followed up by raising her hips and slamming them back down in one smooth, swift motion.

Taro instantly pulled out of the kiss. "Ngh, fuck, Xen!"

Xen said nothing. She only panted and did it again. She slowly built up a rhythm, raising her wide hips and gloriously thick ass, only to slam them back down. Taro could almost feel the bruises threatening to form. Through it all, Xen never once stopped clinging so very tightly to her lover's shoulders, laying on him and pinning him to the couch with her mass.

Taro completely lost control of his voice. Each movement made him grunt or groan or moan or something else entirely. And he loved it.

It helped that each downward movement ended with his steadily-swelling balls slapping his mate's sopping wet cunt. Though he couldn't see them, Taro felt like his testicles were easily twice their original size.

Then his penis pushed upwards again. This time, it did so ever so slowly, pressing further inward a single millimeter at a time. It crawled up like a climber clawing their way up a sheer cliff.

And like that climber, Taro felt himself very rapidly reaching his limit. "X-Xen..."

"Hold it, babe," she promptly whispered into his ear. The ear that now sat on his head, long and pointed like an equine. "A little more, stud, just a little more --"

It was then that Taro felt a barrier deep inside her, he felt it with the rapidly flaring head of his cock. And gods did that flare feel absolutely divine inside his lover.

More importantly, he managed to squeak out, "Xe-Xen that's your --"

"Yes it is," she panted out. Xen paused her ride just long enough to sit up straight. "Get your fat fucking horsecock in my womb, Taro. Flare inside me!"

Taro had nothing to say to that. Before he could think of what to say, exactly as she demanded started happening. His penis' tip was flushed with heat, blood pumping through it furiously as it swelled up and out more and more. Each time his glans was pressed further against her cervix -- Arceus he's deep enough to feel her cervix -- she squealed in sheer joy and pleasure and his dickhead flattened out more and more like an equine's penis.

Despite his trepidations about going this far into his mate, the way his nerves lit on fire from just how good it felt overrode his worry almost instantly. More than that, Taro very clearly felt his flesh swelling at his groin -- probably into a nice, thick sheath.

Taro was pulled away from that wonderful sensation when Xen suddenly stopped slamming against him.

"Xen?"

"G-Get..." she groaned through gritted teeth. "Get in there!"

With an almighty shove, Xen forced Taro's fat tip past her cervix. It wrapped around the underside of his head and Taro's mind went almost completely blank at how perfectly it squeezed -- and just how right it felt.

Despite his empty mind, he still managed to register his balls pulsing, throbbing --

And finally he came. Taro groaned, long and low. He felt his cum surge up, up -- he let out a grunt as it forced not one, but two extremely sensitive fleshy rings to pop out along his length.

The instant he fired his first ever equine cumshot, Taro's cockhead flared wide enough to almost perfectly cover the interior of Xen's cervix.

Neither of the newly mated lovers were remotely silent. Taro continued to groan, Xen moaned and squeaked with each shot that hit her inner walls.

It took several long, glorious moments before Taro felt his senses trickle back in to his mind.

"Xen, I... holy fuck, Xen. Are... are you okay?"

"Yeeesssss..." Xen hissed out. She slowly lowered herself back to laying on her mate. "I may have overcooked the spell a little. Your cum is a lot thicker than - mmfff - than I expected. But yes. I am more than okay, mate. I am ecstatic."

"Doesn't... doesn't getting... isn't that supposed to hurt?"

"It's normally exceedingly painful," Xen readily admitted. "Like getting your dick twisted into a pretzel and kicked."

Taro winced. "Oh Arceus, Xen, I --"

Xen firmly shut his muzzle. (Only then did he notice that it had finished growing in.) "Shh, Taro. Trust me on this -- what you did to me was absolutely magnificent. I guarantee you'll do it just about everytime we fuck in the future and I cannot wait for it."

Taro felt his brows frown heavily. "I... explain, please?"

Xen giggled a bit. "Centuries ago, my cervix was accidentally, temporarily, made to feel just as good as the rest of my pussy. If not better, something like a bit of my clit mixed in. Only one Pokémon managed to hit me there. It's a hidden kink of mine that I rarely get to indulge in. But with you, my beloved mate..."

Taro huffed a bit, a smile tugging at his muzzle at that title. Xen chuckled a bit.

"Mhm. I love calling you that. My beloved mate. With you, you'll do that to me every time we have sex. For you and you alone, I altered myself this way. Even if, at some point in the future, I get railed by someone with a big enough dick, only you will trigger this from me."

Taro licked his lips. He had to take a moment to think. "Is... Is it that good for you?"

"Yes, dear Arceus, yes." Xen squeezed her tunnel a bit. Instantly Taro gasped as yet another glob of cum shot into Xen's stuffed womb. "Just as good as how full you've made me. Would you like to see?"

Taro immediately said, "Yes. Wait --"

Xen sniggered. "Direction doesn't matter. Going in or out, your dick going through my cervix will feel absolutely wonderful."

Before he could respond, Taro felt her remove the makeshift blindfold. He had to blink rapidly several times to adjust. As he did so, he watched as Xen sat up. He licked his lips at the colorful cum coating her stomach, undoubtedly from when he first started changing.

But more importantly, he could just barely see the outline of his dick in her. Experimentally, he flexed his crotch. Both of them moaned. And he saw that outline twitch in time with it.

"Heh... told you that you'd be big," Xen said softly, proudly. "Hold tight and watch our crotches, babe."

She grabbed his hands and moved them up to her thick thighs. He obeyed and squeezed tightly. He kept his eyes glued to where their groins met. (Though he did sneak glances at her face; the focus on her muzzle was both adorable and very sexy.)

Xen pressed upwards with her legs and hands. There were several seconds of them both biting their lips to try and be silent -- then Taro's dick finally slipped free of his mate's womb. Immediately, his seed and more of her cum drizzled out. As soon as it touched his flesh, his crotch fuzz began shifting to a bright white color.

Xen managed to keep herself mostly silent as she moved off her lover's rod. Though she definitely clenched instinctively when his medial ring passed through her nether lips. But given that she still felt one inside her --

"Damn... definitely overcooked the spell..." she murmured. "Wasn't supposed to give you two rings..."

"I'm not complaining," Taro assured

"Of course you aren't, it must feel pretty damn good."

"Yeah," he agreed. "Especially when coming out of my mate."

Xen giggled at that.

At last, with a gasp from them both, his massive throbbing meat was set free from the confines of her tunnel.

It noticeably didn't move much from that position, still very much erect. Though his dick did bend somewhat and spurt a shot of cum onto Taro's chest.

Just like his crotch, fur immediately started growing. He didn't notice. He was too busy staring.

"Holy hell, Xen, I'm like... a foot and a half long!"

"One foot ten inches long, and an inch and a half thick - unflared." Xen smirked. "I did warn you."

Taro huffed. "Yeah. But how am I...?"

Xen grinned. "Goddess of life, love."

"Heh. Fair."

It was at that moment that Taro felt his penis begin to soften. The blood flooding it began to go elsewhere -- and with it, the transformation spell.

He gasped as his legs cramped, relaxed, cramped again -- over and over for several moments. Glancing around his mate, he saw his legs stretching out ever longer. But more than that, his toes, his feet looked more than a little familiar.

Xen followed his gaze. Her eyes went wide and she gasped. "Oh... oh Arceus, you... you're... holy shit."

"Xen?"

Rather than answer, she leaned down and mashed their muzzles together. She shoved her tongue into his mouth and very vigorously began making out with him, an act he returned in kind. Throughout it all, Taro felt his blood pumping up and down his body in ever-growing force. His very heart was becoming larger and larger, stronger and stronger.

When he felt the fur on his groin meet with that of his legs, Xen pulled away.

She whispered, "You are even more of my perfect mate than I had ever expected."

"That's quite the title to love up to," he mused quietly.

"And yet you do. I told the spell what I wanted: the target of my spell, my mate, to have an equine penis big enough to enter my uterus and spread my vagina very wide. And I told it to pick whatever Pokémon form suits you best otherwise." Xen looked down at Taro's changing legs.

They now bore pristine white fur, with gold highlights wrapping his knees and going down his legs onto the top of his clenching feet. They both watched as they grew tighter and tighter, keratin covering his toes and converging them into tough hooves. His shins and thighs stiffened for several moments as they swelled and bulged with tight muscle, only to immediately soften with a big layer of fat.

Aside from the white, his legs looked almost identical to Xen's.

"You're turning into a Xerneas," Xen whispered. "The odds of that happening were astronomical. You are literally my perfect mate."

"That's a thing?"

"Yes. You aren't the first. Dialga has one, Kyogre has one. You're turning into my alternate color, though. White and blue, rather than black and blue."

"You're going to have to teach me."

"I'll be very glad to. But first..."

With remarkably steady legs, Xen stood from the couch. It squeaked loudly in protest after the significant activity. Taro licked his lips -- his steadily more rubbery, equine lips -- as he watched his gorgeous mate stand. And the way their mixed mating slid down her inner thighs.

Xen giggled a bit and held out her hand. "Get up and carry me to our bed."

Taro grinned. He took the offered aid, and though he was unsteady at first, it took only a moment to stabilize. Then he bent and scooped her up. He enjoyed the way she squeaked and squealed out of sheet excitement. As if in response, nearly all of his muscles bulged with a surge of pure power. He also gained a solid half foot in height.

He was also just as eager to continue fucking; his dick pushed out another burst of... not cum, but rather precum now.

Xen giggled. "You're going to absolutely mess me up tonight."

"It's the least I could do for my beloved mate."

Xen giggled again and buried her muzzle into Taro's collarbone. He groaned as she started to lick and suckle his flesh through his growing fur. Despite the distraction, he still managed to walk them both over to their bed.

With each step, his legs grew longer and longer, his torso filled out with more and more with muscle and fat.

And his body rapidly coated itself in a base of pristine white fur.

As the couple entered their bedroom, Taro had to pause as a very unusual and distinct sense of power started to flow through him. Out the top of his skull, his short hair merged into eight very short horns.

"Ohhh," Xen gasped out. "Those look gorgeous, mate. You're going to be so fucking handsome."

"It's... nng, the power is intense, Xen," Taro managed to get out between grit teeth.

"It is. Focus, Taro. Look me in the eyes."

Taro did so. Just doing so, staring into her sea-blue eyes in that beautiful face, was enough to help him focus.

"We can work on learning later," she continued. "Put me on the bed. Pin me down. Rut me."

Taro felt something within his brain flip at those last two words. Immediately his breath and heart rate quickened a little. His balls swelled even further, straining his already heavy ballsack. He watched as Xen licked her lips on excitement.

So, he did as she requested. He went and put her on the bed, on her back. While he liked taking her from behind, he wanted to watch her expression as he took her.

Xen shivered in sheer anticipation. "Yeess, Taro... take me. Take me however you want."

Taro huffed, "Not true. Anal is still off limits, yeah?"

Xen rolled her eyes. "Yes, it is. You know what I mean."

He did. He also knew what he wanted to do right now, more than taking her cunny again. He pushed her a bit further back on the bed, and moved to straddle her. He gasped at the way her soft, velvety fur caressed his cock. He groaned at how he could feel her body heat and her heart beat through his tool.

"Ah, I see," Xen murmured. "Want to fuck my tits, babe?"

"Yes."

Obligingly, Xen brought her hands up around her breasts. To her surprise, however, Taro grabbed them. He shook his head a bit.

"I'll handle that part," he explained. He moved her hands further down, towards his very generously sized testicles. "Fondle these, hmm?"

Xen panted out of sheer excitement. Through touch alone, she could sense just how full the orbs were. Almost instinctively, she began to massage and rub them between her fingers.

Groaning above her, Taro had to fight back the urge to just let her do so. He forced himself to focus, and groped her massive boobs. Squeezing just a bit tightly, he had to put in a bit of force to shove into her cleavage.

"Ggh," Xen groaned out. "Fuck, this is hot..."

Taro almost responded. But he was interrupted when Xen tilted her head forward enough to lick the very tip of his urethra, the bit sticking out of his flat head.

It took all of his willpower to not just start thrusting like a mindless stallion.

Instead, he pulled back, nice and controlled. Just until Xen almost had to let go of his orbs. Then he pushed back forward twice as fast. Xen gasped and grunted as her breasts jiggled from the force. A dollop of breastmilk spurted out of her nipples in response.

"Taro --"

She couldn't say anything else. At that moment, her lover did another pull and push. Each centimeter he did, another centimeter of horns pushed out of his skull. Each bit just made him get ever closer to losing control.

Xen didn't object in the slightest. Rather, she just did her best to memorize the sensations. The way his sheath hit her underboob, how his balls rocked in her palms and pulsed with so much seed.

With each movement, more and more precum soaked her cleavage and tits. It mixed with the milk that his fucking forced out of her nipples.

Xen found herself groaning out, "T-Taro..."

Apparently he took that as a hint. Or perhaps he was that close himself.

Either way. Taro immediately pulled back from between her tits, grabbed her inner thighs and pushed her legs apart just enough to very roughly shove his entire length into her.

Right on through her inner limit. Xen slammed her head back onto the bed, stars dancing on her vision. She wasn't stunned for long, because he leaned down and began making their tongues dance between their mouths once more.

He pulled backwards out of her tight cunt. He idly noted, and enjoyed, the way she whined, desperate to be filled again.

Taro gave her what they both wanted.

He gave it to her as roughly as he could, fucking her with his fat flaring cock and his thick dual medial rings.

Throughout it all, his horns grew ever longer. His fur finished growing in, gorgeous light blue framing his face.

The precum and milk that he'd fucked out of them both on her chest mingled with his own chest fur. Taro groaned as it seeped into his chest. He migrated his hands from Xen's thighs -- she had then wrapped around his waist anyway -- and instead moved one to her hips, and the other to one of her tits.

And then on to his own chest. With a shocked, strangled gasp, he shoved forward into his mate and came. Harder than he had earlier. Due to how full she already was from then, his cum immediately began spurting out from between their coupling.

Taro didn't really notice.

Instead, he was more focused on his hand on his chest. The way that it felt so wonderful to grope and squeeze, pulsing in time with with heartbeat.

And the way that with each pulsing throb his cock gave as it heaved yet more cum out of him, his chest swelled bigger and bigger, grew more and more sensitive. The muscles along his back and front grew tighter and stronger, easily holding up the growths.

Until, at last, Taro collapsed on top of Xen, panting.

Xen was too busy getting down from her own high to notice.

"Xen?"

The slightly concerned tone from her lover helped her reorient. "Hmf. Fuck I'm full, babe... you're heavier than you were..."

"I've got tits."

Xen finally peeked between them. She smiled. "That you do. Same size as mine and already full of milk."

Taro glanced down. Indeed, his new breasts were already leaking.

"Ooh, and your ass and hips are as big as mine... gods you're hot..."

Taro huffed a bit. "So what, I'm a dickgirl now?"

"Something lime that it seems. Objections?"

"Mmnn." Taro forced himself to sit up and look himself over. "Not... not right now."

"Good." Xen sat up, careful to keep herself full of his dick, and kissed him. "Would you like to continue?"

Taro smirked. He pulled himself out of her. "Turn over."

It took several very long, ecstasy-filled hours for Xen and Taro to have their fill. For the moment, at least. By this point, Taro was completely transformed.

He stood a full foot taller than Xen, but he was still a white-and-blue bipedal Xerneas. He kept glancing down at his wide feminine hips and nearly FF-Cup breasts that was still pushing out more milk.

Stepping out of the house and bringing his focus away from his new body, Taro was greeted by what seemed to have brought Xen by in the first place. Around his farm was the herd she guided. Mingling with them was Striker and a familiar Rapidash mare.

"Dash?" Taro called. "Is that you?"

The herd stopped and looked over. Striker frowned at what he saw. Dash, however, glanced at Xen and first rolled her eyes, but then nodded.

"It's me," she said. "I'm sorry I ran off like that..."

Taro blinked and glanced at Xen.

"Yes, understanding Pokémon comes with the change," Xen told him. She grinned as she hugged his arm. "My mate."

"Wait really? Congratulations!" Dash called over.

"Thank you. We came over this direction because during a bit of trouble, Dash lost sight of her foal. I'd forgotten you had moved out here. I'd known you were in the town, which is why I'd not had panties on. So when I found her here and went to ask and you answered the door, I got... very distracted."

Taro nodded in understanding, but he was focused on the way Striker kept looking between Dash and Ponyta, sniffing them both.

"Her foal? Dash...?" Striker began.

Dash nuzzled him. "Yes. She's ours, my stallion. And yes, I am still yours. As we promised, forever and always."

Taro chuckled a bit as his starter immediately became intensely interested in learning more about his foal.

He wrapped his arms around Xen and last his head on hers. Though he'd not expected things to go this way, at least it still meant he would get to spend the rest of his years with the love of his life...
