Umbreon walked into the kitchen, surprised to find Maddie digging through the fridge.

“Glowstick?"

Maddie said, pulling her head out to see who'd just entered.

“Yeah… What are you doing?"

“Nothing."

That's unconvincing. He thought to himself.

“Hey, you want some salami?"

Red flags shot up through Umbreon's brain. She was up to something.

“Nope! Last time I let you put something in my mouth I spent the week beached on my own dick. If I want some I'll get it myself."

Maddie shut the fridge suddenly, giving Umbreon a “Hmph!" before crossing her arms.

“You had fun, didn't you?"

Umbreon walked up to the pokemon water fountain next to the sink.

“In a very technical sense, yes."

He pressed down the foot pedal and lapped at the stream.

“Sooooo, why not let me try something else?"

He stopped drinking.

“Tell me what it is first."

“But that ruins the whole surprise! You won't just trust me?"

She gave him her best puppy eyes, hoping to win him over. There's some irony in there somewhere.

“Fine. Just gimme wha- URK!"

Umbreon's mouth was filled with the savory taste of salami before he'd even finished his sentence. His body automatically tried to awkwardly chew the food, but Maddie hadn't done a particularly good job hiding the pill and Umbreon only managed to swallow it after wrestling with it for a few seconds.

“Gah! You really couldn't wait, could you?"

“Sorry! I'm just so excited! I got a whole bottle of these things, and I can't wait to try them!"

She held out one of the pills. The thing was fucking huge! No wonder he'd had a rough time trying to swallow it!

“Are you going to tell me what it does now?"

Maddie hid the bottle against her chest.

“Nope! This one doesn't act as fast and I don't want to spoil anything!"

Umbreon sighed. It was already in his body. There wasn't a whole lot he could do about it anyway, and throwing the thing back up almost certainly wasn't worth it. How bad could it really be?

“Fine… Can I know how long this is gonna take to kick in at least?"

“Hmm… About an hour."

“And it lasts…?"

“Stop worrying about it, you worry wuss!"

Maddie tossed the bottle into a cupboard, and slammed it shut.

“C'mere."

She knelt down, Umbreon unable to resist stepping forward to place his head in her hands.

“You'll be fine, big guy."

Maddie scratched his cheeks, working her way down his chin. Always a favorite of Umbreon's. He sighed.

“If you say so…"

“C'mon, let's go watch something while we wait."

Maddie stood back up, and the two made their way to Maddie's room.

…

Maddie had thrown up a show on the tv, Alternative Carbink, and the two watched from the comfort of the bed. Umbreon was finding it hard to focus towards the end of the episode, he was too warm, and just generally uncomfortable. Maddie noticed his fidgeting.

“Can you feel it?"

“I feel something."

Umbreon shifted again to lay on his side. His stomach felt weird.

“It's not great."

Maddie hopped behind him, laying down to spoon with him.

“I'm sorry."

She started giving him some gentle pets.

“It's worth it though I promise."

“It's not too bad."

Umbreon didn't want her to feel too bad, even if she was the one who pressured him to take the pill.

“Just a little uncomfortable."

The feeling only lasted a few minutes, and soon all Umbreon felt was the heat. It just kept getting warmer and warmer.

“Maddie, can we open a window?"

“Really? It's only like 18."

She ran a hand through his fur.

“You are really warm though. You want an ice pack?"

Umbreon started to get up.

“No, I… I just…"

He was panting. What was he feeling? It wasn't quite arousal, but it was making his shaft push out of his sheath nonetheless.

“I… NGH!"

Umbreon winced as he hardened all the way up in a single throb. He bucked his hips. Umbreon couldn't move himself, he'd lost control to the involuntary parts of his brain. Pre poured out of his tip, the solid stream unreal as Maddie watched. Her face lit up.

“It's happening!"

It wasn't so much that Umbreon felt pleasure, as much as the acts themselves were pleasurable. So he was confused when his body came without him, ropes of sperm shooting from his peen without him ever reaching that high. But it did still feel really good. Even as he began to shoot dry, Umbreon couldn't bring his hips to a stop. And everything still felt so good! What- is happening-!? A tightness was forming in his crotch, and he felt his junk shrink! He could tell in the way it shook when he bucked his hips, and in how the weight hanging from his crotch was noticeably lighter. But surely Maddie wouldn't want his dick smaller, right? … Right?

But even as Umbreon felt all his nerves flatten out against his groin, the process never stopped. He wasn't even sure it was there anymore. But something was. He could feel it. Spreading over his crotch as it puffed up into- NO WAY. SHE DIDN'T. The feeling spread inside his gut, and his flush, sensitive outside burned with sensation. Maddie had made him a girl! Even through the heat, he still recognized the feeling of liquid running down skin. He didn't know how to respond. His body was still ignoring anything he tried, and drowning any truly coherent thought out with pleasure. It felt so tight, so sensitive! All while Maddie was getting the show of her life, practically drooling as she watched her starter experience having a pussy for the first time. The heat was starting to come down, but Umbreon couldn't shake the arousal. He managed to steady his hips, and hold a stance with his back arched. He didn't realize how heavy he'd been breathing when he was finally able to hear over his own heartbeat again. He turned to look at Maddie, who was so engrossed in watching him that the tv might as well not have even existed.

“T-this *hah* it?"

Even his voice had changed. He sounded far more feminine, almost girly. Maddie nodded, watching him in awe as he tried to get used to a new sex.

“How does it feel?"

“Hot."

Umbreon admitted, still feeling warm from the transformation.

“I'm afraid to move."

“You need help?"

“Yes please."

Maddie caught one of Umbreon's sides, and only with his joints unlocked did he realize how sore all of that had made him. Maddie helped him into a sitting position with his back against the headboard, giving him full view of himself. It was jarring to see his crotch so smooth, save for the tip of his new glowing cookie, still swollen and leaking. It felt good, in a way. Being so smooth, so feminine. It made him want to wiggle his hips. Maddie placed a hand on his chest, and stuck out her tongue.

“Feeling better, big boy?"

“Y-yes…"

He'd be lying if he said he wasn't. She ran the hand down his front.

“OOOH!"

Umbreon was caught by surprise when she got down just above his groin. His nipples had puffed up, and even more, the tissue below them had swelled somewhat. He had proper mammaries.

“Or would you like me to start calling you 'girl' now?"

Umbreon's forepaws bolted down to press Maddie's hand further into his teats.

“P-Please! Don't…"

He felt his labia pulse. He was already worked up from before, if she kept teasing him he was going to lose his mind. He was so close already! So on edge-! Maddie brought up her other hand, and used her thumb to gently press on and spread his tender lips.

“Don't what?"

Umbreon came. Her fingers on his new equipment and the stimulation from his teats was enough to make him cum in his already over-aroused state.

“NYAAA!"

Umbreon yelled as he spasmed, rippling wave after rippling wave rolling through him as he felt his body contract in pleasure. Each sensation brought on a new moan, like nothing he'd ever felt before. His orgasm was so intense! He could feel his inside wring and twist around themselves, and he fantasized about what it'd be like if he actually had something to squeeze in there… Maddie was stunned. Apparently she'd underestimated just how worked up and oversensitive the poor vee had been. But boy did he put on a show, thrashing against the pillows, moaning in his new adorable voice, and squirting loads of girl cum on her hand and the bed below.

“Now how did THAT feel~"

Umbreon wasn't really in a state to form words, much less sentences.

“Guh… Bree..."

Maddie climbed up next to him, pressing her side into his.

“I'll let you ride this one out. And afterwards…"

She leaned into his ear.

“You can tell me how long you wanna stay like this~"

…

Umbreon had managed to roll onto his stomach, still half recovering from the recent orgasm. His heart rate was only just coming down. He rolled the bottle in his forepaws.

“They just suppress my Y chromosomes?" He asked out loud.

Maddie took back the bottle.

“Yup! Brings those dormant X's right out of you! Means it doesn't work for girls though. Real shame."

Umbreon sat up as she placed the bottle on the nightstand.

“And you can't have two within 48 hours of each other, otherwise you risk mixing things up."

"And not in a fun way."

Maddie turned back to him.

“You up for another round yet?"

Umbreon tensed.

“M-maybe?"

He felt like his recovery should've been longer, but he could feel his arousal building again already…

“Because we haven't even gotten to the good part yet~"

Maddie slipped down her pants, revealing she'd already activated the mod for her dick. The half hard organ fighting with her panties. Umbreon's face had never felt so hot. Suddenly her presenting the thing had a little more weight to it.

“You just gonna stare?" Maddie said, scotching closer.

“Well… w-what am I supposed to do?"

Umbreon couldn't help but feel inexperienced like this. He'd only been a girl for 20 minutes at best! It also didn't help that he thought they were going a little fast…

“Let it out! Unless…"

Maddie bit her finger, and let her hair fall over her ears.

“You wanna watch me get harder and harder until I bust out of these?"

Umbreon's face shone yellow, his blush glowing through his fur.

“Alright alright! I'll do it!"

Not wanting Maddie to tease him any longer he swiped at her panties, tugging them down enough to free her stiff erection. But as it came out, Umbreon found himself paralyzed again. He couldn't take his eyes off her hard shaft as it now bobbed in front of him. Sure, something about it made him hot. Made him want to experience it. But at the same time it felt so imposing, an uncomfortably intense feeling of concern he just couldn't shake. And Maddie could see it in him. Time to lighten the mood. She tackled him into the bed, hugging him tightly as she nuzzled his cheek.

“We can start with something else."

Being held really helped. Umbreon relaxed, his head finding the crook of her neck.

“Thank you…"

Maddie smiled. He was so adorable~ She gave him a big smooch, right on the side of his face. Umbreon was feeling a lot better as Maddie kissed him some more, making her way down his neck. He let out a hot breath as Maddie repositioned to keep going, kissing down his front as she headed for his pulsing, glowing cookie. Maddie now had her head between his legs, looking up at him along his underside. The view made Umbreon hot. Maddie gave his swollen femininity the same treatment, teasing the delicate lips with a few pecks.

“Mmm!"

Umbreon moaned.

The sensations still all felt so new, like someone had turned the sensitivity of everything up by 10. He found himself rubbing his teats with one of his paws.

“You really seem to like that, huh?"

Umbreon flushed his usual glowing yellow.

“I- I can't help it…"

Maddie brought a hand forward.

“Did much even change here?"

Umbreon shivered as she placed it on the supple section, feeling it up. She could touch so much! And her fingers were so dexterous, gripping and squeezing things in a way impossible for paws.

“I guess it is more squishy…"

Maddie pressed more. Umbreon was suddenly hit with a wave of pleasure, much more than he expected from just the shallow mammaries.

“Ahh!"

Maddie grinned as she slid her hand to his waist, the other joining in on the opposite side. Maddie holding his waist really made Umbreon feel even girlier. This feminie body… it made him crave touch, to be rubbed all the way from head to toe. To feel every nerve fire one after another. Every bit of contact only drove the fantasy further into his mind.

“No more distractions."

Maddie once again had her head in prime cunnilingus position.

“I'm having myself a yellow cookie."

Even just her tongue's initial contact on his outer lips made him tremble. She wasted no time prying him open, pushing the fleshy organ inside. Umbreon tensed up. Holy shit! Even just her shallow prodding had him writhing in pleasure. Maddie put his whole vulva in her mouth, massaging those puffy lips with her own. Held in place by his hips, Umbreon could only squirm as Maddie went to town on him, driving her tongue deeper and teasing his outer parts. He couldn't seem to stop making noise either, cute little moans and cries spilled out under his new feminine voice. Meanwhile Maddie lapped it all up, slurping away at her glow vee's new box. But this wasn't to be the grand finale, Maddie wanted to REALLY show her partner what having a love tunnel was all about. Umbreon whimpered as Maddie pulled off him, withdrawing from his soaked muff.

“Why… Why'd you stop?"

Umbreon managed to pick his head up enough to peer at her over his stomach.

“Because you dingus."

Maddie crawled back up, positioning herself over him.

“Don't you wanna know how it feels?"

Umbreon's ears went flat and his eyes went wide. Maddie was still rock hard, her erection thrumming in an already lubed up hand as she got herself ready.

“Ho shit…"

Umbreon's voice was nearly a whisper. It'd all been leading up to this. Maddie leaned in closer.

“You ready?"

Umbreon braced his forelegs against Maddie, pushing up on her shoulders as if trying to keep her back.

“S-slow! Please…"

“Of course."

Maddie crept forward, the crown of her shaft meeting Umbreon's glowy opening. It was as she bored down on him. Umbreon could feel his previous anxiety had gone, molded into something that made his heart skip at the prospect of Maddie wanting him. That made him shiver at the thought of what it would feel like in his deepest parts. Was this… excitement? Maddie gave a small shove, her glans slipping right in from both the liberal use of lube and Umbreon's already wet entrance. He gasped as it went in, already much thicker than anything Maddie had shoved in him before. She held him there for a second, letting Umbreon really get a taste of what was to come.

“You're really warm cutie."

Maddie cupped his cheek, guiding him to look at her. Umbreon was still trying to process it all.

“I feel hot…"

Maddie smiled. She rolled her hips forward, sinking in more length.

“Ahhh!"

Umbreon cried, feeling foriegn parts of his insides forced apart, rubbed and caressed by pulsing shaft. Maddie suppressed a moan.

“Fuck! I always forget how this feels…"

But she pressed onward, more and more of herself opening up Umbreon's depths. The whole time Umbreon watched as she went, his moans growing louder and more frantic as he felt her get deeper and deeper. He cried out as her crotch met his, Maddie's entire throbbing length buried in his new folds. Maddie flexed her manhood, basking in the feeling of full penetration. Damn was he warm! Umbreon's whole sex was contracting around her, working muscles he'd never had before. Umbreon just stared at the union between them, panting as the barrage of pleasurable sensations kept coming and coming. She felt so FUCKING DEEP! As Maddie pulled back, his toes reflexively curled. Sure the emptiness she left was unbearable, but the feeling as she glided her way out along his walls… He couldn't help but let out a throaty moan. Maddie had given up trying to maintain eye contact. It was just impossible with how much the two were tossing their heads side to side or squeezing their eyes shut in pleasure.

He may be the one experiencing the other side for the first time, but Maddie wasn't exactly a seasoned dick wielder. She kept her thrusts slow, not only because he'd asked but because she probably wouldn't last either if she tried to speed things up. But she wasn't sure Umbreon even noticed. He seemed busy gasping and moaning, inhaling sharply whenever she fed more shaft into his tight channel and whining softly each time she withdrew. Umbreon couldn't believe how it felt. So sensual, and tight, and filling, and gratifying… Everything made him shiver, made him curl his toes and dig his blunt claws into Maddie's shoulders. He would unconsciously tuck and stretch his back legs on a whim, curling them in only to extend them back out when some new sensation rippled through him. The only reason he realized he was close was because he knew the feeling from earlier. Maddie could tell he was going to blow too, and would have no issue cumming with him. Umbreon locked up as Maddie made one final thrust, his body doing its very best to ensure she was as deep as possible. And Maddie was more than happy to oblige. She pushed her hips to his, pressing hard enough Umbreon's cookie made contact with the upper part of her cleft.

Umbreon barely started his orgasm before Maddie added in hers. The seizing of his body only made worse as Maddie swelled inside him, unloading warm globs in his deepest parts. Umbreon clenched his teeth, groaning in his girly voice with each mind-numbing contraction. The growing warmth in his middle and the flexing shaft inside his cooch made him feel like he was going to melt. All the strength in his body drained into those clenches, his convulsions and trembling more important to maintain. Maddie was pretty sure she'd never get used to the intensity of a male orgasm. All that pleasure packed into such a small space… She could feel her inner thighs soaked by her neglected snatch. Maddie huffed a big sigh, pulling out her already soft length as she sat back on her ass. Umbreon groaned. It had been so much… was he leaking? They both took a second to catch their breath, the room suddenly feeling rather stuffy.

“So? How was it for you?"

“B-bb… bre…"

Try as he might, Umbreon couldn't get words to come. No part of his body seemed to want to work after such a powerful orgasm. Somehow he seemed even less coherent than last time.

“Wow, that good huh?"

Maddie withdrew the penis, her crotch returning to its smooth state. She scootched closer to Umbreon, getting a closer look. He was OUT. His limbs trembled, completely limp as he mumbled deliriously to himself. His eyes caught Maddie's and he tried again to say something.

“Umm… Bree…"

Maddie giggled.

“Alright cutie bre, I know what you need."

Maddie flopped down next to him, exhausted herself. She pulled Umbreon close, spooning him.

“Get some rest glowy. You earned it."

One of Maddie's hands drifted over his stomach. Was it… taught? No, she couldn't have possibly done that… Umbreon was out in an instant, his breathing shallowing out as he slipped into a nap. I fucking LOVE my umbreon <3.
