Sky Does Science

Lightning struck the tower as early afternoon settled over Canterlot, and a mad cackling erupted from within.

Shadow trotted down the stairs, expecting to find the entire room full of smoke again. She was wearing a little blanket over her head, with four holes cut for her eyes and ears. All told, she’d look far scarier if she didn’t have two soft, slightly floppy ears poking out. Shadow, it seemed, made for a poor harbinger of death.

“What is it this time?” She sighed, pushing open the door and recoiling almost instantly. “Oh Luna-fucking-damn it, SIS!”

“Shadow! What’ve I said about knocking?” Sky huffed, pulling her lab coat down over her flanks again, covering her shame. Her mane was far more matted and untidy than normal, and that was saying something. It looked like she’d stuck her hoof in the mains at least once since the incident at the marketplace.

Of course, Shadow thought to herself, she probably has.

“Nice costume.” Sky grinned, looking ghost-Shadow up and down.

“You too.” Shadow giggled a little. “Um...are you sure you’re supposed to wear safety goggles and glasses at the same time?”

“Probably not!” Sky shrugged, trotting in circles a few times before stopping to rub her forehooves together.

“Still fixated on getting Carbon in the sack?” Shadow guessed. “I can offer a few tips if you like.”

“Tips?” Sky turned around. Her pupils dilated slightly, and Shadow recoiled again.

“Ooookay, that was creepy.” She chuckled nervously. “Um...well you know what colts really like? Surprises! I mean, you already tried just walking up to him when you were dressed as methane, right? Well, what if you kind of gave him a shock this time? You know, pop up while you’re dressed as benzene. He’ll be so surprised and overwhelmed that he has to sleep with you!”

“Shadow...you’re a genius!” Sky giggled, bouncing up and down with excitement. Her wings had somehow found a way to become even more untidy and unpreened.

“Aw, come on sis, you know I’ve got your back!” She gave an easy smile, waving her hoof dismissively. “Don’t even mention it!”

Sky beamed at her little sister, her current insanity and hormonal overload blinding her to the way the filly’s eyes flashed dangerously. “Well, I owe you one!” She grabbed Carbon’s day planner and leafed through it, grinning as she reached today’s page.

“Ooooh, he’s at home right now! There’s tons of ways to give somepony a fright at home!”

“Go for it. Trust me, this is 100% guaranteed to get you laid!” Shadow grinned, patting her sister on the flank. “Go on! You don’t wanna miss him, do you?”

Sky’s eyes widened. “Oh shit, you’re right! Thanks Shadow!”

And with that, she kissed the filly on the cheek and leapt off of her balcony.

Shadow sat there in silence for a time, blinking and staring at the wall as she listened to the various crashes and galloping noises that heralded her sister’s departure. When she was certain that she was alone, she pulled the sheet off of her head, cackling madly.

This was going to be fun.

“Caaaaaarboooooon…” Came an eerie, ominous voice.

Carbon sat up on the couch, staring around with his ears perked. That certainly didn’t sound like Lilo. It was somehow more dissonant, more desperate, more...scary.

“Caaaaarboooooon…” whispered the voice again. “Come out and plaaaaay with meeeeee…”

Carbon was all of a sudden very aware of how dark it was in the living room.

“Li...Lilo?” He yelped, before clapping his hooves over his mouth. That had come out at a much higher octave than he’d meant it to.

Suddenly, there came a very loud thud, coaxing an incredibly girly squeal out of Carbon. His eyes darted around the room, searching for the source of the noise.

“Lilo...help?” He squeaked, wrapping his tail around his forelegs and hunkering down.

Over time, however, the voice died away completely. There was nothing left but Carbon, a dark room and the sound of the rain outside.

Carbon, however, was no alumnus of the “What Not To Do In A Horror Movie” class of ‘84, and as the afternoon began to wear on, it struck him that he hadn’t yet showered. Getting to his hooves, he gave the living room one last cursory glance before trotting up the stairs, grabbing a towel and retreating into the bathroom.

Sky grinned as she unzipped the sofa cushion she’d been hiding inside, eyes drifting out of alignment again as she giggled madly.

She could hear the shower running upstairs, knew that even if he was listening that there was no way that he’d be able to hear her coming. Nonetheless, she crept as quietly as she could up the stairs, licking her lips as she began to pick the bathroom’s lock.

He’s gonna be mine...he’s gonna be all mine… Sky giggled quietly as she jiggled the tumblers into place, sliding her tongue into the barrel of the lock and twisting it open. Perfect.

She giggled as she heard Carbon singing in the shower, hidden from view behind a translucent curtain. Sky crept into the bathroom, slowly closing the door behind her, quietly singing along to the Table of Elements Song.
The little white mare, clad in her safety goggles and lab coat, stopped just short of the shower, licking her lips and
wiggling her flanks like a predator about to pounce on its prey.

“HEY CARBON!” She yelled, pulling the shower curtain aside and grinning merrily.

Carbon gave a very girly shriek indeed, slipping over onto his flanks and backing right up into the corner. “WHAT DO YOU WANT? WHAT DO YOU...oh, damn it Sky!” He whimpered, shivering with fright.

“Awww, look at you! You’re all cold!” Sky pouted, clambering into the shower with him and
nuzzling his cheek, giggling quietly. Her eye twitched a little.

“I’m not cold...you just...startled me...and...erm...are you all right?” He shuffled over to the opposite side of the shower, eyes so wide that they were in danger of dropping out of his head.

“Oh, I’m better than all right…” Sky giggled, trotting up to him and booping his nose. She turned her tail on him, before pulling her lap coat up.

There were six letter “H”’s arranged around her plot, drawn in the same black marker.

“I’m benzene!” She announced proudly, pressing her flanks against him.

“Um...very creative Sky, but...that’s just a ring of hydrogens…”

“I know!” Sky giggled, turning around and pressing her muzzle against Carbon’s. “You know, it’s only benzene if there’s a Carbon in the middle of the hydrogen ring…”

“Actually, there’s a smaller...ring...of…carbons…in there…” He put in weakly.

“Details details! What matters here Carbon...my dear sweet Carbon...is that it’s up to you to fill in the middle of the ring…” Sky grinned, putting a forehoof on his chest and beginning to gently run it through his wet fur.

“You...what, now?” He gazed up at her wild eyes with sheer terror.

“Come on Carbon, I’ve got some electron pairs that you’ll just love...” Sky whispered.

“Okay, this is kind of getting creepy...um...Lilo?” Carbon yelped, hooves slipping on the tiled floor as he backed right up against the door.

“It’s not going to work, Carbon.” Sky giggled madly, advancing on him. “Your little waifu’s out on the town at the moment. It’s just you and me here, and you’re MINE! ALL MINE!”

And with that, she wiggled her flanks and took a leap, tackling the poor hapless stallion to the floor.
