A few strands of hair seemed to spring up out of the normally immaculate mane of a purple princess. By her nature, Twilight Sparkle was a mare slow to anger, but today was proving to be especially frustrating and anger threatened to burst onto the surface. Twilight stood in front of a chalkboard, floating several books and some chalk in front of her, scribbling in an almost violent manner as she glanced from the books to the chalkboard and back again with narrowed eyes. On the chalkboard were most of the known biological chemical reactions that had to do with the activation of a mare's spring heat, including various chemical structures of related enzymes and pheromones.

"Ugh! It just doesn't make sense!" The chalk in Twilight's magical grasp broke. She glared at it as if it was the cause of her problem. "Spike!" Twilight yelled at the ceiling as if she were howling.

The head of a small dragon poked meekly from the entrance of the tree house's kitchen adjacent from Twilight's study room. "Yes, Twilight?"

Twilight snapped her head around to face Spike and twitched her eye at him. "Coffee!" she barked at him and her wings flapped as she stomped on the ground.

"Right away, Twi!" Spike saluted and disappeared back into the kitchen. He knew that when Twilight was on a research binge it was best to stay out of the way until she found what she wanted, or burned out and fell asleep. However, he also kept a secret stash of tranquilizer he could slip into her coffee if things went too far. It was a last resort. Twilight was incredibly good at what she did and it was rare that Twilight failed at finding the solution to a scientific problem. Despite it being early in the morning, Twilight had somehow already managed to work herself into a frenzy.

As she watched Spike go, Twilight glanced down to scowl at the strange article of clothing she was wearing. Panties. She usually went around nude, but today her body insisted on producing much more lubricant than usual, so she stuffed some absorbent tissue under the panties to solve the problem. It was a temporary solution, but it was better than nothing. Suddenly, her eyes widened and started to water as she felt another wave of heat. It was a tingling itchy sensation that she could not scratch. She raised a hind leg up and whimpered in futility as she felt her insides clench with desire. With calm breaths and determined, focused self control she felt the tingling pass with a shiver.

Twilight gritted her teeth and growled. The potion/chemical concoction she cooked up every year to suppress her heat seemed to do absolutely nothing this time. What had changed? She looked at the chemical equations, lists of enzymes, and pheromone variations. It had to be something new. The potion she created was known and well designed to suppress all known vectors of heat activation. She had thoroughly searched the books and by all rights her potion should be working. It was time to try something different. When a scientist does not have enough information it was time to test, but she needed some samples.

"Here's your coffee, Twilight." Spike appeared in front of Twilight as she was thinking deeply.

Twilight took the cup in her magic and smiled at Spike. "Thanks Spike, sorry for snapping at you. I'm having a particularly tough science problem and I think that some other mares might also be having a hard time." Twilight was pretty sure that it was not her alicorn biology that was causing her problems because her sensitive pony muzzle could smell the heat of lots of other mares. To make matters worse, it had never spread so quickly before. This year it seemed to all happen in a morning when in the years before it took almost a week before all the mares got the heat.

Spike, blissfully unaware of the mating season, raised an eyebrow in surprise. "Really? How do you know?"

Twilight sighed. "I'll tell you when you're older, Spike."

Spike put his claws on his hips. "I think I'm old enough to know whatever it is you're talking about."

Twilight looked at him carefully. "You know, I think you're right but I can't talk about it right now, I have problems to solve. I'll do it later. Deal?"

"Deal, good luck with whatever is bothering you so much." Spike turned around and walked away.

Twilight looked down at her coffee and took a sip, pondering how to pinpoint the cause of this unusual circumstance. It had to be something that spread quickly because it seemed to have affected all of Ponyville in one morning. It was unheard of for such a reaction to spread so quickly. Her first instinct was pheromones, but what could be so potent? Assuming whatever caused this was airborne, how could she even detect it? Twilight scrunched her muzzle in thought and took another sip.

She suddenly thought about the coffee strainer and her eyes lit up. That's it! She grabbed the door with her magic and swung it open, galloping outside. She smelled the faint, familiar scents of multiple ponies with the telltale accent indicating their heat. Yes, she thought. She could make this work.

She teleported a small, portable chalkboard and the broken chalk she had inside and started calculating a spell matrix for a semi-permeable magical shield. The shield would need to have nanoscopic holes large enough to allow small particles to pass through like elemental gasses and smaller particles like water vapor and carbon dioxide. The holes in her shield also needed to be small enough to trap larger particles like the carbon based pheromones. Twilight smiled, this would do the trick.

She spent the next ten minutes designing and calculating the semi permeable membrane of her magical shield and checking her work. Finally, she pictured the spell matrix she designed and channeled her magic to create a gigantic spherical shield above her, in front of her treehouse, 30 meters in diameter. Slowly she shrank the shield and most of the air passed through. At first it seemed like nothing was happening but as it continued to get smaller, Twilight finally started to feel pressure. Finally, once the shield had shrank to the size of a grapefruit she was feeling pressure but now that the shield was so small she could easily continue to shrink it despite the extra pressure. Finally, once the shield was about the size of a golf ball, she was satisfied. This sample was sure to be rich in the more complex organic carbon based gases and aerosols.

Twilight trotted back inside with a grin on her face and climbed down the stairs into the basement where she kept her lab equipment. She searched through the various instruments, and quickly spotted what she needed. A gas canister. It was a very specialized piece of equipment with a valve on top and bottom. There was also a burner on top and a tray for ice on the bottom.

Twilight turned on a pump and attached the hose to the bottom valve to pump the air out of the canister to get it as close to a vacuum as possible. Once done, she closed the valve. Twilight then carefully lined up the spherical shield of compressed gas to the top valve and allowed the mouth of the valve to penetrate she shield. She opened the top valve and the vacuum inside the canister sucked the trapped gases inside the shield into the canister. Twilight shrank the shield until all of the gasses were inside the canister and she closed the valve.

Now it was time to turn the canister into a magical centrifuge. She lit the burner on the top of the canister and deposited some ice from her nearby lab freezer onto the bottom of the canister. Usually, a centrifuge was a device that spun extremely quickly in order to force heavier particles to the bottom and lighter particles to the top. However, Twilight had the advantage of being a powerful magical protege supercharged by her alicorn status. So instead of needing an extremely expensive centrifuge to separate the different types of gasses, Twilight simply cast a very powerful gravity spell on the canister.

The increased force caused the heavier, more complex particles of gas to sink to the bottom near the cold of the canister and the lighter, less complex particles to rise the top of the canister where the burner kept it hot. Twilight's eyes narrowed as she kept up the powerful gravity spell. Almost ready to go, Twilight screwed on a smaller glass canister to the bottom of the makeshift centrifuge and opened the valve a tiny bit to allow a sample of heavy gas to escape into the container. She cast another scanning utility spell which gave the gas color by type. Once it started to change color she closed the valve and sealed the smaller canister. She repeated the process and filled the small gas canisters with the component gases separated by induced gravitational force and temperature gradient.

Now Twilight had four bottles of mystery gasses separated by particle density. One of them was bound to contain whatever mystery agent she was looking for. Pony noses were quite sensitive, so she thought that perhaps she could identify the samples at least partially by smell as a preliminary test. She started at the least dense bottle of gas and cracked it open to smell the strong smell of methane. Twilight wrinkled her nose. Well, now she knew what that was. She tried the second flask, odorless. She shrugged and opened the third bottle. She immediately recognized the concentrated, pungent musk of multiple ponies mixed into one sample. Now for the last flask of gas. This one contained the heaviest and probably most complex compounds. Twilight opened it and took a whiff.

She did not sense any smell. She closed the flask. For a few seconds she was disappointed and started to formulate a plan on how to further identify the gasses. Suddenly Twilight began to feel lightheaded, her eyes dilated and became unfocused. Her heart began beating at a faster rate, and she began breathing heavily. Simultaneously, her vulva began winking uncontrollably as her vagina undulated under her panties and excretion oozed out into the absorbent tissue. Twilight suddenly felt a burning feeling of need and her breathing continued to intensify until some saliva drooled out the corner of her mouth and an involuntary whinny noise escaped her lips.

Twilight's eyes widened as she suddenly realized what had happened to her. She fought to regain control over herself. The gas inside of the fourth canister undoubtedly contained some sort of concentrated sexual catalyst. This was exactly what she was looking for! She had isolated whatever was causing this. Twilight wiped a fetlock across her mouth to clear the saliva and gave the bottle a predatory smile.

Twilight continued by subjecting the mystery chemical to a series of tests to try and determine which pony pheromone it was most closely related to. However, it did not seem to react the way any of the conventional pony pheromone aerosols she had listed earlier did. Twilight creased her brow and rubbed her chin with a hoof. An aerosol that was not like any known equine pheromone yet effected mares all the same.

What in the world could have produced such a mysterious chemical? It had to have been related to the equine species because it obviously affected equines. Perhaps a new mutation? Or perhaps a dormant, hidden gene expressed by a pony that had just the right parents to unlock it. Whatever it was, Twilight needed to find the source. This interesting phenomena could provide insight into how genes worked. Perhaps she could even write a scholarly paper on it. The very thought made her giddy with excitement. Ever since Anon had shown her the power of science with his versatile phone, Twilight had resolved to put greater effort into understanding science instead of simply focusing on magical fields.

Twilight focused her magic and used the scanning spell to focus on the gas. It was a modified version of the spell Rarity used to find gems. She experimentally tuned the frequency until the gas glowed, revealing its presence within the bottle. Perfect! Twilight knew exactly what to do now. She downed the rest of her coffee and galloped out the front door to take flight with a notepad and pen in her magical grip.

Twilight began scanning the open air. She didn't see any glowing for a while, yet continued to fly in a pattern searching for any trace of a glow. As she began to fly out of town, Twilight noticed a faint glimmer almost invisible. Gotcha! She focused the scanning beam from her horn and looked around. The glimmering wispy light seemed to become brighter and more intense in one direction. She continued following the slowly dissipating glow and the glow became more and more concentrated as she started to approach the source.

The glimmering became more and more intense as she followed the glowing river until it suddenly terminated at the opening of a chimney. That was strange, she thought that it would have lead to the door. The gas didn't seem to be emanating from the chimney but instead slowly dissipated, retreating into the chimney. Perhaps the air conditioning was turned off and the air was simply not being pumped out, it was still strange.

Twilight hovered over the edge of the roof and was surprised to see that this was the place where Anon lived. She creased her brow. Strange compounds never seen before would logically originate from an alien, but Anon's biology had nothing to do with equines. She also heard rumors that Blossomforth had moved into Anon's place and that they were in a romantic relationship. Well, at least Anon had adapted after Twilight had unfortunately and accidentally abducted him. Twilight saddened in lingering shame. She would find a way to open that portal again.

Anyways, Twilight needed to investigate the source of this powerful airborne chemical. The sign read open, so perhaps she could do some poking around. Twilight hovered downward and landed in front of the door. She pushed to door open and walked in, the tinkling bell announcing her presence.

----

Blossomforth's world was a warm haze, the abomination was utterly intoxicated with lust as her amorphous body slid and stuck to Anon's smooth skin. Several greasy tendrils extruded out of her flesh and reached out to slide around the curve of Anon's body. She felt the pounding blood pressure tighten Anon's arteries under her powerful flesh. She tasted the salty sweat and the pheromones within, savoring his unique taste as it excreted from his oily pores. She tightened her powerful, flexible, amorphous muscle around Anon and felt his weaker, less efficient muscles tremble under her grip.

He was vulnerable, she realized as she held him in her grasp and a sinking feeling caused her powerful muscles to tremble as well. She could even smell his fear. Sorrow and shame pierced her mind, she wanted to cry at how cute and fragile Anon seemed to be. It wasn't fair, she wanted to be the small helpless creature but she was cursed to being this powerful monster. A powerful need demanded that she smoothly slide a tendril into his most private area and envelop him in her fleshy embrace to caress him in the most intimate of ways and coax his valuable, delectable seed into herself. She almost did it, a tendril slowly inched its way there, curling and flexing powerful muscles with desperate desire. Twisting veins popped from her clenching, pulsating, muscular tendril blossoming forth as it grew. Heaven in the form of a new world of biological information was just inches away waiting for her to slither forward and intimately extract it.

There was nothing Anon could do to stop her, his supine acceptance of her dominance was like an invitation. Anon knew what was going to happen and he had accepted it. Even if he wanted to stop her she could easily ooze around whatever barrier he tried to erect. It was the most natural thing in the world, what she was meant to do. Her excited tendril began to slide into his boxers but right before she made contact she dimly heard her name being called out to her.

A cold knife stabbed her conscience.

Blossomforth couldn't do it. Every instinct and iota of her body demanded she close the millimeter gap between her tendril and Anon's penis but her mind resisted. Her tendril flexed, wriggled, and bulged with desperate, grotesque convulsions of warring actions but did not extend forward. Blossomforth would not allow herself to become a true monster. A being that Anon loved because he had no choice. Blossomforth felt sick and went completely opposite to her instincts. Inching her tentacle backwards away from Anon's penis felt like she was pulling the nail of her hoof out of its socket. It was painful to her, withdrawal symptoms caused her to shake and shiver. She denied her body its very purpose and stars appeared in her mind, splitting pain scrambled her thoughts.

The pain increased exponentially as her will waged war against her instinct and her awareness faded but despite this, Blossomforth felt like a hero. She tried to reach out to him but her tentacle seemed heavy. She felt someone hold her tentacle up. Her name echoed in her mind, Anon was calling out to her and it sounded important. She smiled internally and relaxed as the darkness took her.

----

Anon felt the powerful tendrils extend around his torso and arms under his shirt and grab him forcefully. He tested his strength against them, but they were like bands of steel and he could not move against them, they locked his arms into place and squeezed into his flesh a little uncomfortably. He noticed that the fleshy bands started to pulsate more rapidly as she seemed to be working herself into a frenzy. They pounded against his skin and gripped him harder with desire.

"Hey Bloss, you're grabbing a little too tightly."

He looked over to Lyra's mangled body, and to his sudden fright he saw that Blossomforth's face which was on Lyra's head had deformed and melted leaving a mismatched glob of facial features. Blossomforth either could not or would not hear him. The bands of muscle and sprouting tendrils wrapped around him keeping him virtually immobile. He suddenly felt real fear as he realized that he was in the clutches of a frenzied, horny monster. Anon knew what was going to happen. He was going to lose his virginity. Hopefully, she wouldn't hurt him.

Anon felt powerless, there was no choice in this matter. He felt Blossomforth's lithe, fleshy tentacles powerfully pulsate against him and he shivered weakly against them. Anon cringed in pain as the bands of muscle bruised his flesh, imprinting long lines of red where the tendrils grabbed him with lust. Anon felt the tentacles curled around his legs force them apart and a tendril slid into his underwear to pulsate more quickly and forcefully. It curled and wriggled in seeming glee. His instinctual purpose as a male, the strong, dominant protector was violated. He surrendered himself to her, accepting that he was going to be manhandled and dominated, completely used by a superior organism. After all, it was only in the alien's nature. Blossomforth could not control herself, the temptation was too great. Tears of powerlessness and love glistened in his eyes.

"Bloss. I want you to know. I forgive you, I love you."

The tentacle stopped right before it touched his penis and bulged as if straining. It began to shiver and convulse, the pulsating became faster and faster, he felt the bulging veins against his skin becoming tighter and tighter. Anon started to groan in pain. Finally, the tentacles shivered and trembled and suddenly went limp. He felt the tentacles and flesh under his clothes deform into a viscous consistency. The organic matter flowed out of his sleeves, his shirt, and down his pants. He felt the organic sludge flow down his shirt and Anon tried to hold it but the sludge flowed through his fingers and puddled on the floor.

Anon kneeled down and tried to feel or grasp the puddle of organic sludge on the floor but his fingers slipped through the puddle. As he began to pull his fingers out he felt something press against them and he pulled out a fleshy tendril that curled around his fingers barely hanging on to him as he held up his hand. The tendril extruded out of the puddle as he pulled it out and went limp in his hand and Anon grasped the limp appendage softly. Anon didn't know what to think but he reverently kneeled there in silence.

The jingling of a bell announcing somepony's entrance shattered the moment more effectively than a gunshot.

Anon felt his stomach drop as his adrenal glands flexed and excreted what was left their load into his blood stream. Thinking fast, Anon glanced back at the mismatched, mutated body of Lyra. Anon stood up quickly to scan the room, the adrenaline dulling the pain he felt after being abused.

To his horror, the tendril had adhered to his skin and he could not get it unstuck, the adrenaline and testosterone forced him to detachedly analyze his situation. As he pulled the tendril stuck to his hand upwards more of the ropey flesh was forced to emerge from the puddle, as more of it emerged the organic puddle shrank as it attached itself to the extruding rope of flesh. Anon quickly spotted the stack of towels and pivoted to propel himself over to it, dragging the tendril along with him. He grabbed the towel and looked behind him to see that the act of him dragging the tendril out of the puddle caused the entire mass to transform itself into ropey flesh, smooth and brown, almost like a thick snake. Anon hastily tossed the towels over Lyra's mutated body on the massage table.

"Hello? Anyone here?"

Oh shit, Twiggles was here. What the hell was she doing here? Anon fearfully stared at the hallway, he definitely did not want to be forcefully experimented on... again. That powerful magic of hers mixed with a neurotic mad scientist vibe could be downright terrifying.

"Gimme a minute Twi!"

Anon started to hear her hooves clop on the floor as she walked towards the room he was in. Shit! A sudden burst of inspiration caused Anon's eyes to widen. Anon stared at the tail of the tendril stuck to his hand. It looked like the tail of a snake. Anon quickly wrapped Blossomforth's unconscious muscular form around his neck like a scarf and flipped the other end back around his shoulder. Twilight suddenly popped her head around the corner, her horn was glowing and a haze of sparkly wisp sparkled in front of her making it a bit hard to see. She smiled at him.

"Hey, Anon! How you doing?"

Anon leaned against the massage table with Lyra's covered body trying to seem nonchalant.

"Alright, doing alright Twiggles. Still keeping busy with your crazy science experiments?"

Twilight smiled but twitched slightly as she felt a bout of sudden lust caused by the thick haze of Blossomforth's biological aerosol sparkling in front of Twilight.

Twilight grunted but responded. "Yes, actually. I learned a lot from you and your phone and have been putting more effort into unlocking the secrets of science. Which is why I’m here. I am going to keep this quick because of... Ugh." Twilight shivered visibly with lust.

Despite his predicament, Anon started to worry. "You okay Twi?"

"Yes, fine, fine. Anyways, if you didn't already notice." Twilight glanced around at the haze her magic revealed. "Today is the first day of the spring heat. To make a long story short, mating season. I am investigating an unusual chemical pheromone which I have determined to be originating from this building. It seems to work extremely well and has even overridden my potion which I usually use to control the urges that come with this season. The haze you see before you is the chemical I have been tracking with my magic. I seriously doubt that this is coming from you because it affects mares, but I was wondering if Blossomforth was somewhere around. I think she may be expressing some sort of rare gene, so I wanted to know if I could take some samples from her or just poke around to determine the origin of this chemical."

Sweat began to bead on Anon's brow.

"Well, I am going to be a bit busy and a relaxing atmosphere is needed to perform in my line of work. Blossomforth just left after she came back for lunch. How about a bit later after I am done?"

Twilight frowned. "It will only take a few minutes, I'll be quiet."

It was time to bring out the big guns. "Alright, but you have to be quiet and Slithers here will be roaming around probably nipping at your hooves, he loves visitors."

Anon gestured at his neck where the fleshy snakelike form of Blossomforth was wrapped around his neck. Twilight squinted through the haze but her eyes widened at the sight of the smooth skin of the huge 'snake'. Her irises were as big as dinner plates.

"I-I-Is that a s-snake?"

Anon grinned. "Yup! Fluttershy had us take care of him for a few days, I'll be returning him in a few hours. He's sleeping on me right now but he'll probably wake up soon and he loves new ponies. He'll wrap himself around you as his way of greeting, he loves the body heat."

Anon started to walk towards Twilight and Twilight's wings sprung open and she backed away crouching slightly as she did. "I-I'll be back in a bit! I'll try to make some new modified heat suppression potions. Maybe it can help Blossomforth control her unique pheromone."

Anon continued to walk forward. "You sure you don't want to pet him before you go?"

Twilight's voice cracked and became comically high piched, "I'm fineseeyoulater-bye!"

Twilight practically dove for the door in her haste and yanked it open with her magic to take flight as she exited. The bell jingled violently.

Anon watched Twilight hastily fly away and pet the smooth skin of Blossomforth's long unconscious tendril form wrapped around his neck. Her flesh was warm. Every so often it would twitch to his touch. Anon sighed, his face was a visage of worry, weariness, and exhaustion.

"Oh Twiggles, you are such a silly pony."
