Not everyone gets a Pokemon partner to become a Trainer or Performer or Breeder. Sometimes, we pick a Pokemon Partner or partners because we just need that companionship. Humans and Pokemon alike desire love and intimacy, that special connection that unites two souls and makes them one.

Times have changed since the days when my great-grandparents arrived here in Sienta. A hundred years ago, Pokemon were still seen as nothing more than dumb beasts, useful for cheap labor and little else. To be caught having sex with one (even the most human-looking of 'Mons) was to be charged with bestiality, with the human put in an asylum and the 'Mon euthanized. The only noted exception was being lucky enough to hook up with a Legendary, as those tended to be rare and considered "religious experiences" (Arceus knows how many religions, cults and belief systems were started because a godly Pokemon wooed or was wooed by a charismatic human).

It took decades of activism, legislation and the occasional intervention of the Legendaries themselves to get to a point where it was socially and legally acceptable for a woman to marry her Machamp. Thus far, Sienta has only legalized marriages between humans and Human-like Pokemon in the last twenty years, with relations between humans and others only decriminalized five years ago. Even now, outside of the Trainer and Breeder communities, being outed for plowing your Houndoom could be a death sentence for your social life and career.

None of this was on my mind when I was given my Eevee. I was already a sophomore in high school when I decided I wanted a Pokemon partner. I had friends of course, but I never had the chance to go on a Pokemon journey due to an accident when I was nine. Long story short, walking long distances is painful and exhausting, and it's pretty hard to go "roughing it" in the woods when you have to use a motorized scooter to get around. Still, even if I couldn't have a super-powerful or dangerous Pokemon, I wanted someone who could protect me and that I could consider a friend.

Which is why I got Eva. Yes, I know, Eva the Eevee, how original. But what she lacked in original naming, she made up for in affection and intelligence. Everyone likes to think that their partner is so smart, the top percentile of their kind of Pokemon, but she truly was smart as a whip. On a whim, I started teaching her English, just to see if it was even possible. Within two weeks, she was able to form full sentences. I knew that Pokemon could sometimes learn to speak a language in exchange for losing an attack or move, but the rate that she took to speaking was truly impressive.

After I graduated high school, I took some courses in Pokeball design, hoping to get a career in creating equipment for Pokemon trainers and breeders. I was able to get an entry-level job at the Sienta branch of the Poke Company, answering calls, doodling designs on the side. Between this and a small inheritance from my grandparents, Eva and I were able to rent an apartment a short distance away from work. We were overjoyed, to say the least, to be independent and on our own. Eva, in particular, was very happy to be as affectionate with me as she wanted, without weirding out my family.

The relationship between Eva and I has always been... unique? Yeah, let's go with that. She has something of a Bold personality, which has nearly gotten us into trouble on more than one occasion. Ever since I taught her to speak, she'd been rather playful and even flirty with me. Licking food off my face (and slipping her tongue in my mouth when my parents weren't looking); laying on my lap while watching TV or working on the computer (while rubbing her crotch against mine); kissing me awake in the morning (when she didn't opt to sit on my face); and of course all the innuendos. To this day, I can't believe Eva recited (a highly censored version of) the Vaporeon meme to my grandparents. Thank god they were too internet-illiterate to know what any of that was, I'd never be able to live it down.

Still, despite all of her troublemaking, I still considered her my best friend. She complimented my shy, introverted nature, urging me on to do bigger and better things, to live my life to the fullest despite my disability.

So perhaps it shouldn't have surprised that the thing that prompted her evolution was just us cuddling up one night on the couch, watching some show after a long week, with nothing to do for the next few days. Without prompting, she looked at me and said, "I love you, Master." (She likes to drop "Master" instead of my name whenever she felt flirty). I, not thinking about it but still very sincere, stroked her fluffy back and replied, "I love you too, baby." Next thing I know, BOOM!, she starts glowing like the sun, damn-near blinding me. I'd lost track of time the last few hours, so I had no idea if she'd be evolving into an Espeon or an Umbreon. Instead, when the light dimmed, I was surprised to see she'd grown into a petite, white-pink feline, with "ribbons" stretching out on either side of her body.

"Well shit," I declared, "Eva, you're a Sylveon now!"

"Imma what now?!" She scampered off me, running off to the bathroom to see herself in the mirror. By the time I started getting up and off the couch, I heard her sweet, melodic voice cry out, "HOLY SHIT, I'M HOT!"

"What're you talking about?" I demanded, making my way to the bathroom. Eva had hopped onto the counter, inspecting herself. Her pink ears and tail flicked and wagged excitedly, her ribbon tendrils pulling at different parts of her body. Now that my vision was clearing, I could truly appreciate all the differences between an Eevee and a Sylveon. Her brown-black eyes were now a bright blue. Two little bows atop her head and on her neck covered the pores that extended the white tendrils that pulled and brushed her white fur. All her thick, floofy fur was now replaced with thin, smooth fur that revealed her now lithe figure. Her big, poofy tail was now a long and erect pink tail, leading all the way down to a tight little pucker and a pronounced fortune cookie vagina swollen with heat.

This last detail was what drew my eye. Now, I'm not going to lie and say I'd never thought of having sex with a Pokemon. There were plenty of guys and girls in high school who joked about going to a "Poke-Hotel" and renting out a room with a Gardevoir or Machoke. Hell, I admit sneaking onto the computer while Eva was asleep, watching some Poke-Porn to take care of my needs. I didn't look up too much Eeveelution porn (at the time, it made me feel weird, like I was doing something dirty), but I like my fair share of Vaporeon and Espeon vids and art. Before that moment, I'd hardly even seen Eva's cooch before, it being buried in a thick forest of fluff. But now, seeing it on full display, so full with arousal and need that I didn't know she had, I was caught off-guard as some primal part of my brain activated.

"Like what you see back there, Master?" I snapped back to reality, realizing that I'd been staring at her coochie for a couple seconds. Worse, Eva saw I was staring, and was giving her booty a little wiggle. I quickly averted my gaze, but the damage was already done.

"Don't be shy," She teased, her ribbons reaching back and caressing her rear, "I know you like this. Hell, I'm surprised by how gorgeous I am now. So, why don't we have a little fun and break in this new body?"

"Whaaat are you talking about?" I asked, shifting nervously on my feet.

"Our bond is strong, Master," She explained, hopping off the counter and landing at my feet, "I wouldn't have taken this form if we didn't. There's much love in you, just as there is in me. All I want to do is show you just how much you mean to me... and, hopefully, what I mean to you."

I stared at her, taking a confused step back. I was torn between being surprised and shocked by the bluntness of her proposal, and being aroused and and excited at the prospect of having sex. I hadn't had a girlfriend since high school (partly from lack of freetime, partly from lack of interest), and I'd started coming to accept that I'd live my life as a bachelor and a virgin. That my best friend (and a talking cat Pokemon) was offering to be my first was surreal, and yet I couldn't make myself say no. I was surprised by how quickly I wanted to say yes, but...

"Aren't I too big for you?" I asked, gesturing to us both, "Look at you. Look at me. I don't want to hurt you."

"You won't," She assured me, a tendril gently stroking my leg, "Not if you let me lead. I won't push myself too hard. And I promise I'll make it fun for the both of us, okay?"

I sighed, and shook my head. "There's no talking you out of this, is there?"

Eva smiled. "Nope," She chirped, "Now get your handsome butt back to the couch! I want to unwrap my Evolution Present!"

I sat back down on the couch, kicking off my slippers and tossing aside my hoodie. Eva hopped up onto the space between my legs, her tendrils grabbing my shirt, yanking it off like she'd been doing it for years. She eyed me up and down, considering my chest.

"You know," She mused, tenderly touching my pecks and nipples, "Some 'Mons think this whole 'Dad Bod' look is gross, but not me. I like that you have a little chub here and there. I like being able to use your belly as a pillow. It makes me feel... safe. Secure. Warm."

I smiled, flattered by her approval. Her tendrils took my sweatpants and underwear, and like unwrapping a Christmas present, slowly pulled both down. My erection came free, standing at attention for her inspection. Eva's eyes lit up, licking her lips as she gazed upon the one part of me she'd never seen before.

"Nice." She said approvingly, sitting down between my legs. Her paw caressed my balls, as her tendrils snaked up and down my manhood. Her touch was light, tantalizing, magical. "Must be five, six inches of meat here. Exactly what I was hoping for. I've done my research, you know. If you were packing an eight-incher or more, I'd have to turn into a Vaporeon to handle it all. But since you're average-sized, you're just big enough to make this a fun little challenge."

She leaned in and gave my dick a long, delightful lick from base to tip, and I shuddered. She licked me again and again, her tongue circling around my circumcised tip like a lollipop. Fuck, I'd never felt anything so good. She looked up at me and gave me a wink, as she opened her mouth wide and took the whole head, slowly pushing down. I couldn't help but moan, amazed and delighted by the warm, wet feeling of her mouth on my cock. She closed her eyes, forcing herself down, and I heard the tiniest gag as my dick went down her throat, her nose booping my crotch. She pulled back all the way to the head, and pushed herself down again, though not all the way to the base. Finding a comfortable range, she repeated the motion, worshipping my manhood with eager adoration.

"Damn, Eva," I grunted, "You're just... that's just... holy shit, girl."

She hummed appreciatively, the vibrations adding an additional thrill. Her tendrils reached out, one gently rubbing my nipples, the other cradling and massaging my balls. Maybe five minutes in her new form, and she was already multitasking with her new appendages. Eva always had talent, but this was a new level.

"If you, keep this up," I warned, "I'm not, going to last very long, Eva."

My Sylveon pulled back, my dick wetly slipping out of her mouth, still hard enough to remain erect and boop her nose. "I know that," She told me, "But I'm not going to last very long either, once I start riding you. But I'm as wet as Seaworld right now, and I'm going to make sure we both enjoy this." She stepped up, my member trailing along her belly fluff, tickling the sensitive flesh. It passed between her nipples (the first time I ever felt them on her body), and she stopped as it brushed her fortune-cookie pussy, my tip touching her entrance. A ribbon went down and wrapped around my dick, holding it in place.

"I'm ready," She announced with a lustful simmer, "Are you?"

I petted her ears, stroking her sides, my fingers curling around her rear. "Let's do it, babe."

Grinning fiercely, Eva lowered herself. Her lower lips kissed my tip, and with a grunt of exertion, they parted as I slipped inside. She winced, her inner walls squeezing me like a vice.

"You okay?" I asked, concerned.

"Yeah... yeah," She assured me, "It's just, you know, first time and all. Lemme try something." The Sylveon gyrated her hips in a slow, circular fashion, swiveling around my dick like hula hoop. The motion didn't do a lot for me, but if her expression was anything to go by, it was a lot better and easier than simple penetration. She whimpered and cooed as she wiggled and spun, sinking lower and lower until I felt her rear resting on my sack.

"Oh yeah," She sighed, "I did it. I took all of you. No one can say I didn't. I'm a Size Queen, now." She held herself up taller, proud of her sexy little accomplishment. I couldn't help but smile back, her joy being so contagious.

Just as carefully, she rose up until only the tip remained inside, before pushing herself back down. She sighed, enjoying this just as much as I was. She moved up and down, up and down, each thrust gripping me like a vice. Every lift was accentuated with a bounce of her ears and tail, and an erotic, needy panting. Her tendrils reached out to me, and I took hold of them. Eva stared into my eyes, watching my reaction to her beautiful dance just as much as I was watching her pleasure.

"Is this... good?" She asked, in-between breaths, "You like?"

"Oh yeah," I grunted, "I like this very much."

"Do you... want me to go... faster?"

"...If you can handle it." I smiled, offering her a challenge. She grinned, and went back to humping me with renewed gusto. She pounded her pussy against my cock with the vigor of a porn star, her cries becoming high and desperate and euphoric. My own pressure was starting to build, and I found myself growling with arousal, my fingers digging into the leather sofa. Her inner muscles were squeezing me tighter and tighter, to the point where I wondered if her juices were magically slippery or something. I was approaching the point of no return, and by the looks of it, so was Eva.

She began to cry out - loud, melodic sounds of happiness and bliss - her tendrils wrapping around my arms. Feeling the pressure building myself, I grabbed onto her backpaws, and started thrusting into her coochie, grunting with each thrust. She winced at first, but then cried louder, faster, almost a pant that matched my rhythm.

"Fuck, Anon!" She screamed, "Fucking cum in me! Fucking fill me up! Make me your fucking bitch! Fu-, fu-, FFFUUUOOHFFUUUCCKKKUUHHH!"

For a moment, her blue eyes lit up to a piercing white, and I feared she might've somehow started mega-evolving or some shit. But then I felt her pussy squeeze me tighter than ever before, her entire body shaking in a blissful, triumphant orgasm. She leaned her head back, howling a climatic cry of delight and rapture. My own orgasm wasn't too far behind: As she rode through hers, I grabbed her waist, and started bucking into my Sylveon. I growled out my horniness and need, thrusting as deep as I could, and I felt the tip of my dick kiss her cervix, and that threw me over the edge. I grunted like I got punched in the stomach, as my balls clenched and I came. The feeling was electric, pleasure filling me from the tips of my toes to the back of my neck. She howled again as I filled her, and I could see her belly start to bloat and fill as I shot my load again and again.

We rode that rollercoaster of heaven for what felt like an eternity, but couldn't have been more than a minute. Before long, Eva collapsed onto my belly, panting and exhausted, yet smiling all the same. I stroked her ears and back repeatedly, earning a satisfied purr as my reward.

"Damn," I sighed.

"Yep," She replied.

"That wasn't too much for you, was it?"

"No, no. I can take on more."

"Good, good. Because I'd be up for being in charge next time."

"Mmmph. I'm looking forward to it."

She climbed up onto my chest, her tendrils grabbing some napkins and cleaning up the mess left behind. With that all done, I turned the TV onto some easy listening channel, and together we fell asleep to the gentle afterglow, dreaming of all the steamy adventures we could get into...
