“Lights up, please.” A voice ordered.
Twlight squint her eyes at the sudden incandescent flash that filled the room, reflected in edgy corners of metallic surfaces, the pristine white floor shone as if it was a lamp by itself.
The gadgets and apparel moved aside as Luna made her way inside the white room, her invisible magic shield repelling everything that could possibly be on her way.
She looked imposing, more than ever. Twilight noticed.
Her starry mane was tied in a long ponytail tall fell over her shoulders, some loose strands neatly covering her forehead. Luna wore a crimson wool beret, perforated in the middle to open way to her horn.
A half-moon brooch was pinned against a a tightly scarf wrapped scarf. The princess looked serious, professional at whatever she was doing.
Leather was something widely seen as a taboo in Equestria, but Luna did not cared about such idiotic point of views.
She loved the texture of rubberized leather, no matter how many pieces of skin were necessary to give her such a pleasure.
A dark waist-band held her personal apparatus together; some she would soon make use.
The princess wore no regalia, but a different sort of outfit, a dictator looking one. You could call it a fantasy, she called it a privilege. Few ponies in Equestria possessed a presence as bone-chilling as Luna.
And she would silently bask on that.
Luna closed the heavy steel door behind her back with a hoof, a loud clank followed by a latching sound echoed through the room.
“Well, the time for your judgment has finally arrived, isn’t it?” She said in a serious tone, inspecting a clipboard that floated in front of her. With a pen, Luna signed something at the bottom line, and made sure that her check list was ready.
Unlike the rest of the castle, this chamber was hermetically sealed, and no air or light from the outside could come in. If there was a place to go when your intent was not to be bothered, that was the place.
It was a wide circular room, a polished steel dome topped over them, ducts and entanglements of wires ran down the walls, all those subjacent structures tightened and crowded together in the central part of the dome, where an aperture allowed the cables to disappear into the maintenance floors above.
There was a constant whirring in the air, caused by a large fan on the wall that served as purifier, constantly pouring cold oxygen into the sealed room.
Electricity-powered equipment were very expensive in Equestria, few ponies could afford an engine of any sort, but in this part of the castle, electricity was everywhere, from the hidden fluorescent lamps behind the shafts of the walls, to the multitude of experimental machines locked inside glass cabinets; a jaw-dropping amount of technology that wouldn’t be released to the public very soon.
Aside from being the centerpiece of the royal technology research department, that room also served as Luna’s playground.
She loved to mess with the new gadgets the science team developed, even those who seemed to be far from useful. Anything that moved, sparkled, flashed, buzzed, vibrated.
Yes, in special the vibrating ones.
The underground complex had been sealed again for the night, and the princess could have all the fun she had planned for months.
But naturally, no fun would be doubled without another pony to share it. Or as she liked to say when in command; another test subject.
Luna bit down her lips, already thinking about the effects of her research; wouldn’t it be interesting to have the help of Celestia’s brilliant protégée? Yes… Yes it would.
Twilight opened her mouth to speak, but a muzzle gag prevented her of doing so. She wriggled in place, already regretting Luna’s invitation.
“Are you nervous, young Twilight?” Luna asked with a chuckle, searching for something inside one of the many cabinets around. “I will make you feel fantastic this night!” She squealed.
Twilight feared the definitions of fantastic... Luna found the steely suitcase she was looking for, bringing it to a table and unlocking it with her own key. It looked heavy, and by the yellow lightning bolt stamped on its surface, she presumed her experience wouldn’t be fantastic at all.
Electrifying maybe – not fantastic.
Twilight clenched her teeth, unable to say a word, her legs were spread and tied to the corners of a stainless steel gurney. The plain surface was cold, and made her back shiver. She felt so exposed, powerless, under the amassing aura of an alicorn deity like Luna.
But at the same time, Twilight felt dominated. A prisoner that deserved a long awaited punishment.
She didn’t know how these thoughts came to be in her mind, but in that mentally torturing room, helpless, watching her mistress preparing the apparatus soon to be tested, an arousing wave of forbidden pleasure permeated her body.
On her back, Twilight tried to lift her head just a tiny bit, to see what was about to be done, but Luna wouldn’t let her do so, always pushing her head back, and threatening to use the neck leash again.
Twilight murmured something under her gag, barely managing to pronounce a muffled sentence.
Luna snickered, touching Twilight’s skin with a hoof, and looking into the younger alicorn eyes.
“I’ll be right back.” She said, disappearing behind a blurred glass wall.
Twilight observed her dark silhouette back-lit by the reflectors as Luna removed her beret and scarf, grabbing another vest. She closed her eyes, just like she’d do when a doctor was about to examine her. That unmistakable scent of leather gloves and ether, the cold touch of their instruments.
Twilight gasped, feeling the gurney in which she was tied bending up, she could now face the room as a whole, with her body in a more comfortable position.
Luna walked away from the glass wall, smiling naughtily at her patient, wearing tight rubber socks on each leg.
“You like my new lab coat?” She asked, turning around for Twilight. “It fits perfectly, don’t you think?”
Twilight nodded, still struggling to breathe with that muzzle gag wrapping her face.
Luna was kind enough to unbelt it, not because she was feeling sorry for Twilight’s agony, but because her mouth would be way more useful without a gag.
Twilight gasped, having a chance to fully satisfy her lungs with cold, fresh air. Her lips and chin were coated in drool, but with her magic disabled, she could do nothing about it.
“T-thank you Luna…” She muttered.
“You’re welcome, 070.” The princess replied, paying little attention to Twilight, just taking her time to adjust the last settings of her equipment.
“W-what?” Twilight tilted her head to the side.
“During the term of this experiment, that’s how you’ll be referenced.” Luna held back a giggle. "I just kidding, silly pony." Luna finally removed two futuristic looking objects from the suitcase, closing the lid with a clank. “These are morphing dildos. And I’ll be testing both of them, so you better prepare thy pussy.”
“But Princess I-”
Before Twilight could complain about anything, Luna stuffed one of the silicone covered members inside of her mouth, the object acting like a pacifier.
The Alicorn used her magic to move the dildo back and forth, while Twilight still struggled to accept the sudden intrusion. Her tongue tried to push it away, but the instrument morphed and changed, dodging her attempts to repel it.
“Just for you to know, it has a semen reservoir on the back.” Luna added, levitating the other dildo, a larger and exotically shaped one. It was thicker on the base, but spiraled to the top like a mutant Dragon dick.
Luna pulled out the pearlescent member from Twilight’s mouth, she coughed, a thick lube trickling down the edges of her mouth.
“Yes, I thought about everything.” Luna chuckled.
“What- I don’t even” The tied princess muttered, confused at the tastes she was feeling on the back of her tongue.
“Magically enhancement dildos. Fantastic, isn’t it?” Luna blinked twice, proud of her creation.
Twilight started to pant, feeling a strange tingling creeping through her body. She blushed harder as she felt a sudden heat filling her pussy. A tingling that crawled over her body.
“Oh, did I forgot to mention that I have introduced heavy chemicals into these dildos? A sexual hormone.” Luna stated, taking out a thermometer from her lab coat pocket.
Twilight flinched as Doctor Luna inserted the cold object deep into her marehood.
“Oh my, you are indeed burning!” She said, waving the thermometer in the air. “I think it’s the perfect time to start out test.”
“It h-hadn’t started yet?” Twilight muttered.
“No dear, I was just inspecting you.” Luna giggled, levitating the large spiraled dildo from the table. At the touch of a button, it started to throb, pulsating as faster as Twilight’s heart.
Luna leaned against the bed, caressing Twilight’s chest with a hoof, as the rubbed the twisted length of the dildo against her slit. Twilight let out a silky moan, feeling her clit being engulfed by the magic texture of that mysterious object.
Climbing on the bed as well, Luna placed herself between Twilight's spread hind-legs, teasing her pinkish lips with the tip of the dildo, the squirming alicorn squealing softly with pleasure.
Luna bit the tip of her tongue, narrowing her eyes as she inserted the first inches of the dildo into Twilight's pleading cunt. A unexpected gush of liquids sprinkling against Luna’s face and coat.
Twilight moaned, panting as the artificial member was pushed deeper inside of her, becoming even thicker and warmer. It felt definitely alive when it changed its form, growing spherical appendages that stuffed her inner walls.
“L-luna It’s too much- I” She moaned loudly, her back arching with each thrust. Luna wasn’t willing to stop. She felt so aroused seeing, feeling, touching the shivering pony under her power.
Her own pussy was drenched and clenching around itself, cum dripping between her legs, and down her socks.
Silently, she grabbed the other dildo, planting it on the bed, and lowering herself onto it. Her sweaty lab coat felt as a second skin around her body.
The two mares panted rhythmically, her muscles stiffening and relaxing as the unpredictable dildos morphed into different shapes inside of their pussies, Twilight felt so full she could explode. Her fur rose up statically as if an electrical current flowed into her.
Luna moved on top of her, the leashes holding Twilight in place being torn apart by the magic of her alicorn master. At the same instant, she wrapped her hooves around Luna, pulling their chests together, the feathers of their wings intermingling in a calming way.
Luna bit down Twilight’s ear, letting out throaty moans as they were fucked together by the magically enhanced dildos.
“I k-knew you would love it” Luna muttered, pushing the glistening dildo against her deepest barriers, Twilight could barely put her thoughts into words, her eyes rolling in pleasure, as the cock swirled around her winking clitoris, applying pressure to hold it back in place. A feeling she never thought she could experience.
“Hngggghh.” Twilight moaned, her hind legs kicking in the air, Luna’s weight was the only thing pinning her body in place.
They hugged tightly as their bodies climaxed at the same time. The lights of the laboratory failed and blinked, after such a strong pulse of alicorn energy being released simultaneously. Luna arched her back, raised her flanks as the vibrator drilled her marehood, making she squirt all over Twilight legs.
A massive amount of cum filled their insides, gushing out of Twilight’s pussy as a salty milk machine. Luna rolled to the side, breathing noisily and pulling out the dildo, as it squirted a thick spurt of artificial cum over her chest.
Twilight’s spiraled member was expelled by her own contractions, and remained still between her thighs.
A long silence followed, as they stared at the ceiling, the hinges in their minds slowly turning again.
“W-well… I guess that was a success!”
“I already said a thousand times, Light Specter, I didn’t touched that freaking table of yours!” Grumbled a unicorn, making his way down the stairs towards the laboratory.
A very annoyed doctor trotted by his side, letting out a long sigh.
“Very well then, so explain to me who for Celestia’s sake could have spilled half a gallon of... Semen, for heaven's sake! Around the lab?” He said. “I don’t know what kind of disgusting tests you’ve been doing, but if I find another-”
“Doctor Specter, I won’t argue with you.” The unicorn lowered his head. “I can barely produce enough fluid to make my wife chuckle."
Light Specter couldn’t help but laugh at him.
“Whoever did that… Must have a penis of a dragon fiend” He said. “But It doesn’t matter, we’ll check the security cameras when we get there.” The unicorn stated.
“Yes… We’ll find the culprit...”
