Born that way.

Sylvia's eyes went even wider, if possible, and she stared at you in a mixture of horror, wonder, and lust. "But I've never done anal before. And you're way too big. You'll never fit!"

"Oh I'll make it fit." You promised, fully embracing your more domineering side. Sylvia squeaked in response and then moaned as you slid your cock slowly out of her. Cum flowed from her pussy once you left her. A testament to just how much you filled her fertile pokemon womb with. "And you'll love it."

Sylvia still looked apprehensive as she rolled over, her pert pink prosterior raising to meet your throbbing cock, still dripping with both of your juices. You admired the tight ass of the sylveon as you spread her cheeks, marveling at her cute pink rosebud. You wondered if her little pucker tasted as good as her pussy, but now was not the time to find out. Sylvia drew in a deep breath as she felt the head of your large dick push up against her butthole, and she mewled weakly as she felt one of your powerful hands push down on her back, holding her in place so you could have your way with her most perverse of holes.

"Oh fuck... oh fuck... oh fuck..." Sylvia whined as she felt you press repeatedly against her asshole, seeking entry to that ultra tight channel. "Oh I don't know if I can take it."

"You're going to Sylvia so just try to enjoy it." Dr. Violet said, her skirt now lifted to show her purple pussy. Which she absently played with. "That human's big dick is going to split your ass in two, so just relax. It'll hurt less if you do."

Shutting her eyes tight, Sylvia grunted aloud as she felt the head of your cock pop inside her ass. You pushed forward slowly, by necessity not choice, as the sylveon had the tightest ass you had ever been inside. Including Gina's. She whined and groaned as you drove deeper, seeking to sink the entirety of your massive meat within her tight little asshole.

"Oh fuck you're fucking huge!" Sylvia gasped and gripped the exam table tightly as you reached the halfway point, with several inches of your cock already spreading the pokemon's asshole wide to accomadate your monster cock. "Are you almost in all the way?"

"Half." You revealed as you started pounding in and out of her, faster and faster with each thrust.

"Half?!" Sylvia exclaimed as her body shook under your thrusts. "Holy fuck, you're gonna destroy my ass!"

"Probably." Dr. Violet answered, petting Sylvia's face with one hand. "But its going to be fucking hot ass hell."

The minutes dragged on for Sylvia as your pounding thrusts succeeded in driving you inch by inch deeper into her asshole. Having just came, your stamina had gotten a boost, and as the ten minute mark passed, you felt like you could keep going. You had nearly reached as deep as you could go, and fortunelty by this point, Sylvia's body was becoming accustomed to her anal invader.

"Oh fuck yes! Fuck fuck fuck! Fucking fuck my ass!" The little sylveon cried, growing more vulger with every inch of your cock you drove into her ass. "Fucking give it to me! I want all of that cock in my fucking ass! Slam it in! Make it fucking hurt! Just like this little fucking slut likes it!"

"Yeah? You want it to hurt my little slut? You want me to destroy your slutty little ass?"

"Fuck yes! Fuck that ass! Make me your ass slut! Fuck me like a fucking good little whore!"

Dr. Violet chuckled. "It seems repeated kisses have had a profound effect on your brain. It seems your cerebral processes are being completley dominated by your arousal. Seriously, the arousal centers of your brain are lit up far brighter than any other."

You and Sylvia scarcely heard the doctor's words. You were too focused on driving the last couple inches of your cock into this pokemon's ass and she was too focused on taking your brutal anal ****. Finally, after nearly twenty minutes of trying, your balls slapped loudly against her asscheeks as you drilled the last bit of your cock deep into the Sylveon's asshole.

"Now I can start fucking your ass." You whispered into Sylvia's ear, causing the pokemon to moan aloud.

"Fuck, I thought that's what we've been doing?"

"Nope. Now is when the fucking really starts." To emphasize your point, you proceeded to thrust furiously into her ass at breakneck speed. You were going to give your favorite fan everything you had to give. You didn't hold back one bit, unleashing every ounce of sexual energy you had plowing into Sylvia's ass.

"Oooooooooooh fuuuuuuuuuuck!" Sylvia cried aloud as she lay on her stomuch and took the rough ass fucking. "Fuuuuuck! Fuuuuuck! Fuuuuck that ass! Ooooh myyyy gooood! Fuuuuck!"

"Alright my little fuck bunnies." Dr. Violet said, her voice sounding breathless as well as she full on fingered herself. "Time for the last kiss."
