The Doctor does Ponyville

"So why am I in the chair now?" asked Twilight.

"Well if you reading on my physiology were inconclusive," he said evenly, "then perhaps taking readings on you will provide more insight.  You've been exposed to the Poison Joke and you already know what it does."

"Yes," she replied, "It makes my horn soft and pliable, and it blocks my magical powers.  But aren't my instruments 'museum pieces'?"

"I've made a few adjustments and upgrades that you would have discovered in a year or two anyway," he answered, "so I'm not giving you anything that's going to upset the balance of technology and magic."

"And... uh... I'm naked because?" she asked as she looked over herself as she was strapped down into the seat.

"Not that I'm complaining," he smirked, "but it was your idea for optimum readings."

"My idea?"

"Indeed it was," he replied.

"I... don't remember suggesting that," she said with a blush, "In fact, with you hovering over me like this... I can't seem to remember a number... of..."

"From what you told me, Poison Joke only produces one effect on it's victims?"

"Yes," she replied, "I got a soft horn that ruined my magic, Applejack shrank to the size of a rat, Fluttershy's voice deepened, Rainbow Dash couldn't control her flight, Rarity's mane and tail turned into a twisted unmanageable mess, and Pinkie Pie's tongue swelled up so much that she couldn't speak intelligibly."

"Hmm," he mused as he read the graphs, "It doesn't make sense... unless..."

"What?"

"Pheromones!!" he replied, "The Poison Joke has somehow altered and enhanced my natural pheromones!  Since they're produced inside my own body, they affect my mind as well as others!  They compel mating even out of season!"

"But how can we stop ponies from smelling your pheromones?"

"It shouldn't be hard to rig up a proper filtration mask."

"For everypony in the area?"

"As long as exposure to me is limited..."

A loud noise from upstairs interrupted their thoughts.  It sounded like somepony was breaking in the front door.

"I better go see what that was," he said as he dashed for the stairs.

"But Doctor," she said, "I'm still..."

She cursed herself for making her chair and its restraints resistant to unicorn magic.  It was going to take her some time for her to get our of them on her own, but her horn dimly glowed as she started working on them.

...

Rarity was taken aback.  She was on the way to answer the front door when it was kicked in.  Standing there was Derpy, but she was staring intently as Rarity had never seen before, and her boobs had swollen to watermelons.  Hot pink spotted watermelons.  It must have been a dramatic change because her shirt was burst wide open and her bra appeared to be broken.  The next thing she knew, the enrage mailmare had grabbed her by the shoulders and pushed her into the wall.

"Tell me where the Doctor is!!" she howled in the tailor's face.  As she leaned into her face, Derpy's now mammoth boobs seemed to pin her against the wall as much as her arms and hands did.

"The Doctor is in Canterlot," replied Rarity.

"No!" she replied, "He's here!  I can smell him!"

"It's lucky that the Doctor still makes house calls," said the Doctor as he stepped out of the stairwell down, "Now let the nice tailor go.  We both know you came here for me, so here I am... I must say your chest has really swollen from the last time I saw you, my dear."

"Yes," she hissed, "when I saw you boning the heck out of this little slutmare over here!"

"Well no one was stopping you from joining us," he replied evenly, "You were the one who turned and left."

"Well I don't know what went wrong," she moaned, "but I want a piece of you right now!!"

"Very well," he answered, "but I don't think the Library floor is..."

"Twilight keeps a bed upstairs!!" she said as she scooped him up and dashed towards the staircase.

Once released, Rarity slipped down the wall as she slumped to the floor.  "Funny," she mused, "Derpy isn't normally so... aggressive."

"Should we go... save him or something?" asked Romana.

"If all she wants is sex," mused Dash, "I don't think it's anything he can't handle."

"But what if in her current condition, her aggression turns to violence?"

"I'm feeling a little aggressive myself," said Pinkie as she leaned into her.

"Me too," said Dash as she leaned in from the opposite side.

Romana was starting to feel just a bit trapped between them as they started nibbling at her neck from opposing sides.

...

The Doctor found himself thrown onto Twilight's bed with great force.  In a blink of an eye, the now out of control Derpy was on top of him, giving him a face full of her new boobs.

"You will be gentle with me, won't you?" he asked with puppy dog eyes.

She responded by tearing away his boxers with one fluid motion.  His cock was already hard and ready for action... again.  Then she tore away her own mail uniform shorts with equal ease, and apparently her own panties in the same gesture.

"Just lay there and let me do the work!" she snarled in his face.

"If you insist, my dear..."

Grabbing the base of his shaft, she made it stand straight up from his crotch.  "Oh, I insist!" she growled as she raised herself up and dropped down, thrusting his cock right up into her birth canal faster than he could have imagined possible.  Then she placed both of her hands on his shoulders as she rode him.

"I don't suppose you're a virgin too?"

"Yes," she moaned, "Yes I am!  Does it matter?!"

"No," he replied as she bounced, "That just seems to be how things are going for me today.  But I take it this isn't how you normally behave, my dear?"

She paused to think about it before saying, "No, I guess... this isn't my normal self."

"Do you recall how you were exposed to the Poison Joke?"

"I... I... my mind so fuzzy... just wanting to mate with you... after I saw you with Miss Rarity..."

"Please.  You must remember."

"I have to finish," she moaned, "I have to finish before I can think straight!"

Minutes passed as she bounced.  He blew his wad into her, and then she climaxed a few moments later herself.

"You know," she said as she panted, "I might think a little better if you stopped playing with my nipples."

He hadn't even realized his was were doing so until he looked at his fingers were teasing her now great nipples into a rock hard state of their own.

"Oh, so sorry," he replied as he released them.

"I... I..." she stammered, "Never touched Poison Joke.  It didn't touch me.  A strange unicorn stallion zapped me with... some wand thingie...  That's the last thing I remember clearly..."

"What could you see?  How did you know it was a stallion?"

"He... he... had a waxed mustache... pointy well trimmed goatee... the rest was under his monk-like robes."

"Feeling better now?"

"The urge to mate with you is gone for now," she replied, "but I can feel it coming back already.  I don't know what went wrong... or how long I can resist mating with you again."

"Hopefully I find..."

"DOCTOR!!" screamed Romana from downstairs.

"It seems there's another house call to me made," he said as he pushed Derpy off her.

She rolled over onto her back as she moaned, "Wow, that really took it out of..."  And then she was asleep even as the Doctor ran to the stairwell.

...

A moment earlier, down in the lab...

...

'This is taking too long,' thought Twilight as her horn glowed, 'If the Doctor's pheromones are messing with me, they should be wearing off soon.'  For all her efforts, she had only unstrapped one hand.  Then she realized that somepony was down in the lab with her, and they hadn't come down the stairs.

Then she felt a hand over her eyes, and another over her mouth.

"Well well," he hissed into her ear, "All strapped down and no place to go?"

"Mmm mmmppphhh!!" she protested.

"Don't worry," he replied, "I don't plan to detain you very long... test subject number 70.  I'm quite eager to see what happens when I use my ray on somepony as brilliant and talented as you."

Even though he uncovered her eyes, she knew the speaker was behind the chair, and his hand over her mouth clearly stopped her from turning her head.  Then something pointy and metallic poked her in the back of her head.

"This shouldn't hurt you... much..." he said as he laughed evilly.  Then she felt her head filled with strange energy as she felt her consciousness slipping away.

...

Back in the moment...

...

The Doctor slipped downstairs to see that Pinkie and Dash had stripped Romana again, and were now licking her all over.  But that wasn't what made her scream so.  A strange sound made him look as Twilight shambled her way up the stairs.  But her eyes were now solid dimly glowing purple orbs, and her expression seemed numb and completely neutral.

"Se-e-e-e-e-e-e-e-e-e-x..." she moaned, "Se-e-e-e-e-e-e-e-e-e-x..."

"What's wrong with her, Doctor?!" panted Romana as Dash and Pinkie had her pinned to the floor.

"This is sheer speculation, mind you," he said, "but it seems that while the Poison Joke affected her magic before, now it's affected her other greatest asset:  Her mind!  She's be turned into some kind of mindless sex zombie!"

"Did you just make that up?!" moaned Romana.

"Most likely."

"And what about these two?!" she asked as Dash and Pinkie licked her crazy.

"It's most likely your pheromones that are driving them into a sexual frenzy," he replied as he looked over the shambling Twilight as she approached them.

"And the crazy one with the giant tits?!"

"I think she fell asleep right after she forced me to mate with her," he replied evenly, "but first she told me that a unicorn stallion zapped her with some kind of ray before she lost her mind and grew those giant boobs."

"So the Poison Joke... has been weaponized?!"

"It would seem so," as he waited for Twilight to shamble closer, "and I have a feeling that weaponized Poison Joke is responsible for our friend's condition."

"How can we cure anypony without her?!"

"It seems our only hope now is the one called Zecora!"

Applejack sprinted into the room as she said, "Don't worry, Doc.  I remember the way we went there the last time."

"Doctor!" called Romana, "I can't follow you like... mmmppphhh!!"  She was cut off by a kiss mouth to mouth from Pinkie.

"I think the sex zombie is going to follow me," said the Doctor as he followed Applejack to the door, "So I think you don't have to worry too much... about things other than sloppy oral sex."

"MMMPPPHHH!!!"

"I promise I'll return!"

"We can stop by Fluttershy's place on the way," said Applejack as she ran, "She knows critters, even the ones in the Everfree Forest!  I think we can use her expertise if..."

"If?"

"We can convince her it's more important than how scared she is of going into the Everfree Forest!"

He grabbed his scarf on the way out and made a rough loincloth out of it.

"That there thing is useful," said Applejack as she glanced over her shoulder.
