Flash Sentry runs track, and likes to stay after school to partake in hot showers within the locker rooms. Contemplating his life after he graduates, he finds that the hot water heater doesn't work one day, leading to a reluctant decision to use the girls' locker room rather than wait for the shower at home. He gets more than he bargained for.

Chapter 1

Another day was going by in a blur for Canterlot High's track team, though not in as literal a sense as many would assume. The team was practicing running laps along the soccer field, smiling as energy coursed through their legs and the sun smiled down upon them with its warmth. The grass gave a pleasant crunch beneath their heels, the breeze kissing them with its cooling touch whenever it blew past the school.

At the head of the line, breathing heavily but proudly as he lead the formation was a smiling Flash Sentry. His cobalt hair was ruffling in the wind, legs pushing him onwards with a spring in his step. His lungs burned with exertion, and sweat dotted his body, but he cared not in the slightest. Far greater things weighed on his mind, particularly as Caramel came sprinting up towards him to catch up.

Flash gave Caramel a smile that was returned almost immediately. "So what're you gonna do after you graduate?" Caramel asked, eyes sparkling with a warm light.

"In particular?" Flash chuckled with renewed vigor as he weighed the question. There was so much ahead of him, it would have made him dizzy were the inquiry a physical force of nature. But it wasn't, and there was plenty of time to sort that clutch of chickens before they hatched, so he merely popped off with, "Go to college, join the military, find someone to settle with." His smile widened further still; there'd be lots of time for planning later anyway. "You?"

Caramel's smile faltered a little, and he jabbed mock-accusingly, "Aw, no time for pals, buddy?"

Flash Sentry laughed. "Of course I'd spend time with my pals! How couldn't I? I got the golden years ahead of me, and so do you!" he replied, turning on the balls of his feet as a corner of the field came up. He and Caramel twisted in sync, missing the fence by inches as they kept up their sprint-and-chat. "I just wouldn't be able to do that as much, once I joined the military."

Caramel's grin reasserted itself. "True. Heard they're stricter than the football coaches."

Flash nodded. "My old man always said as much," he agreed with a brisk nod as he and his friend turned another coming corner. Behind them, the rest of the tide did the same, in fluid sync. Flash could, faintly, hear the goings-on further back. Two members of the track team talked, loudly, about their plans post-graduation. Others only focused on running, as no other sound seemed to leave them. Some still hollered and whooped far behind, but the noises were distant.

Not that he could blame them in the slightest. "Guess everybody's pumped for the end of the year, huh?"

Caramel chuckled. "Seriously, Flash, who wouldn't be?" he retorted.

"Fair point," Flash agreed. "What're you going to be up to, once you graduate?"

Caramel snickered. "Probably going to a trade school and then starting my own little hobby shop," he said. When Flash barked out a laugh, he jabbed again, "Hey, what do you take me for? I'm getting my butt into the police force as soon as I can!" He elbowed Flash, but not hard enough to slow him down, much less topple him over. The two shared a laugh as Flash returned the favor, and kept up their sprint-and-chat along the way.

"Say, I heard Pinkie Pie's throwing the Vice-Principal a baby shower when the graduation party comes around," Flash muttered, chuckling at the thought.

"But hasn't she already thrown one, like, last month?" Caramel asked, still smirking nonetheless.

"Oh no, it's for after her baby's born," Flash replied with a snicker. "Something something 'first party' something something." They shared another laugh amongst themselves, envisioning how wild that party was going to be even with a baby involved.

By the time the track team disembarked from the soccer field, hit the locker room and went off home after, Flash lingered as the sun started to descend. It wasn't quite sunset yet, still mid-afternoon in fact, but now was a prime opportunity for him to have a nice, hot shower in the boys' locker room with some peace and quiet.

There was just one problem. One eentsy, niggling, teeny weeny problem that would have soured any good mood on the spot were anyone else actually present to witness it. He undressed, went up to a shower stall, and turned the knob for the hot water to pour through at juuuuust the right temperature…

Five seconds passed after the knob was turned. Nothing. Not even a sputter met his ears. Okay, weird, but certainly not unheard of. He tried the cold water knob to dispel any doubts, forming or otherwise, in his mind—and winced as a cold blast of ice water sprayed him point-blank in the face. Turning the knob the other way faster than the first, he was able to stop the flow of cold water. Though, he wasn't fast enough to stop the chill from running down his spine as it registered cold from above. Making sure to shut off the hot water knob just in case, he strode over to the shower stall across the room opposite of the one he'd just tried.

He turned that shower's hot water knob, and nothing at first. Again, there wasn't so much as a hiss nor a drop. Though after a few seconds, as if realizing something had been tampered with, this shower head gave a sputter and another spray of ice-cold goodness that wasn't nearly as powerful as it should have been. Indeed, it was less spraying and more dribbling out the water from its many pores.

Flash's brows climbed up his forehead at this anomaly. He turned the knob without even touching the cold-water knob and waited for a minute before trying the hot water knob once more. Another cold sprinkling greeted him, a little stronger but not enough to actually be of any particular use. Off that showerhead was turned, and to the one adjacent to it Flash strode to try his luck again.

Five seconds of knob-fumbling earned him another quick blast to the face, and what a surprise, it was ice cold! He didn't bother with the cold knob, instead turning the shower off to try the rest of the stalls. And those yielded the same result: more blasts and sprinkles in the face that left him shivering through it all. Turning off the last stall, after a few minutes of searching for a hot water source, he began heading for a sink that rested in the corner of the locker room. He frowned a little as he went over to turn its hot water knob.

More cold water surged forth, without any sputtering or wheezing from the faucet prior to the spray this time. Flash turned to the hot water heater that stood next to one of the shower stalls and approached it after turning off the sink's faucet, curiosity aroused. His hand touched the heater itself, its piping, even its own knob—which was strangely cool to the touch and fully turned.

Upon kneeling to see if, perhaps, the foot of the receptacle was hot, it hit him as his hands touched cold metal. He groaned and pulled away, shaking his head. "So much for a hot shower here…" he grumbled, mood now thoroughly soured. "I'm better off walking home naked." He smirked; the thought was somewhat amusing, but not enough to lift his spirits. Besides, he didn't feel like getting into trouble for streaking through town anyway.

He snickered as he could hear himself telling the officer of that fun scenario, "Sorry, didn't feel like being decent on the walk through town because the hot water heater went kaput." He turned and went to a bench near the lockers, where his clothes had been removed and folded neatly atop it with a towel overlaid on the stack prior to this kerfuffle. He picked up the towel and dried himself off; though truth be told, he could've air-dried anyway with how minimally drenched he was, and it wouldn't have made much difference in the end except for a cold.

All the same, he did need some way to take his mind off of the lack of hot water in the water tank. "Maybe the others used it all," he mused with a blaise shrug. "Guess I'll just have to take a shower at home." It had been quite the day at track practice, and he should've expected as much; mentally hitting himself now for not noticing that fun little fact of life sooner until after it had gobsmacked him.

But eh, he just had to take it as it was. It was his fault for not noticing sooner.

Flash finished drying off and slung his clothes on, when a rather absurd thought hit him. Although it was one that made him turn three shades pink even considering it, and in the quiet of the locker rooms, he couldn't help but voice it aloud before he was able to reign himself in. "Would anybody notice if I used the girls' locker rooms for a quick…"

Fortunately for him, that question didn't need to finish itself, and he stomped it down before it had the chance to. He shook his head fiercely, red reaching the ears as mortified horror and embarrassment came in for the one-two combo punch. Convenient? Not unless he wanted several earfulls from Principal Celestia about decency and the like. And that wasn't factoring in what good ol' Mom and Dad would say about the matter as well. Not to mention throwing his whole graduation into jeopardy, were he caught in the act—itself still likely, as faculty had a habit of lingering far longer than the student body ever did. Papers just didn't do themselves in for the grading.

Although… he had to admit to himself, it did seem a rather tempting option. The girls' track team and other sporting teams had probably already gone home by now, tucking in or hanging with friends or doing whatever else they felt needed doing the moment they parted from the school grounds. The proximity didn't hurt much either, though there was still the whole 'keeping the coast clear' issue that needed sorting out.

Between that and the walk home…

Flash shook his head again, but now that the idea was planted in his head by his own stupid hormones, it refused to leave him alone. He frowned, making sure his clothes were fully on before he dared step out into the hall. Picking up his resolve, he marched to the door of the locker room, pausing to listen for any tell-tale signs of a janitor coming along.

Only silence answered to him for a full minute. Though, very faintly, and he had to strain his ears a little to make it out… he could hear something coming from beyond the hall. He opened the door and poked his head out, glancing down both ends to see if it was the janitor.

Nothing, though that noise was a little louder now. If he had to describe it, it would be shhhhhhhhhh-t-t-t-t; a constant, monotonous hum broken up by pitter-pattering that seemed to come every other interval. He glanced up and down the hall, just to make sure. And still, he was the only living soul present… or so it seemed, at any rate.

Walking out into the hall, shutting the door behind him, he did another look-see just to be sure. Once again, he confirmed that there was no wayward janitor to worry about, so with a shaky hand he slowly approached the girls' locker room door and quietly grasped the knob. He did not twist, however, as he noted the sound seemed to grow even louder than the rushing of blood his heart started to pump out.

His gut started to scream "Someone's in there you idiot!", but hormones did a fine job dampening that rational thought as, cautiously, he twisted the knob with a gentle creak. The moment the door even started to part from its frame, the sound hit him full blast—the pitter-patter intensified, and the hum grew just loud enough to compliment it. An airy, yet warm mist started pooling out from the crack, caressing him as if it bade him to enter.

Fantastic. Someone else apparently had the same idea he did. Flash entered and shut the door, quietly to avoid rousing the suspicion of whomever was having a hot wash session. Even though hormones were waging war with rationality, both had come to the conclusion that having someone screaming at him was the last thing he wanted today.

He waited for a moment, just to see if the mysterious shower-user would notice. When only the continued use of the shower answered to him, he started to undress quietly and slowly to avoid drawing attention to himself. He took a chance to eyeball the girls' locker room in its entirety; save a few stickers on the lockers and the warm mist, it was almost the same as the boys' locker room down pat. Then again, he supposed as he folded up his shirt before working on his pants, he figured there had to be some manner of consistency in the building.

Once undressed, he walked up to one of the shower stalls… noticing the one adjacent to it had one of the last people he'd expected to encounter. He gaped, he gawped, he even gave a silent gasp of paling, mortified horror as he started upon the naked and drenched body of one very definitely pregnant Vice-Principal Luna, back turned to him and hands washing her hair. His legs started to move on autopilot, and he found himself backpedalling as fast as he could without looking where he was going.

Luna only turned away from the shower when she heard the distinct clung of someone impacting on metal. She jerked towards Flash as he slumped against a locker in a faint, eyes wide as a pained croak left his mouth.

Flash couldn't tell how many hours or minutes had passed, and it mattered little as he awoke to find Vice-Principal Luna kneeling next to him, looking at him with a slightly furrowed brow and no small amount of surprise and concern. He yelped and sat up straight the moment this registered, looking at her with eyes wide and pleading as a dull ache registered in the back of his head. "I-I'm sorry!" he stammered, pupils shrunk, "I-I just wanted a hot shower! The boys' locker room didn't have h-hot water I didn't mean to see you and—"

Luna lifted one hand, folded all but an index and middle finger into a ball, and held both to his lips in order to stop his running mouth. "Slow down," she said firmly. "First off… are you alright?" At Flash's slow and hesitant nod, she went on, "Second… the hot water heater in the boys' locker room isn't working?" Another nod, that one faster, answered her. "Third… you saw fit to come here… just for a shower?" Another nod, and Flash shuddered as he realized a few things:

First, that last nod merely sealed his fate. Second, the Vice-Principal was still butt naked, which hadn't occurred to him until just now. Third, he was still butt naked. Fourth, and paramount of them all, Luna's stomach was brushing up against one of his forearms. It wasn't due to proximity, though that certainly played a part…

Flash went from blanched to beet red in an instant. By the statue in front of the school, he could feel his whole body heating up!

"Lastly…" Luna sucked in a small breath and looked Flash dead in the eye, leaning as much as her pregnant body would allow. "Do you, perhaps, fancy me as I am now?"

A high-pitched, confused "B-bwaaaa…." was all that left Flash's mouth in that moment. Without any hesitance, or guilt in the motion, Luna gave him a swift but firm pecking on the lips, pulling back only as another strangulated croak vacated Flash's drying throat.

"Answer the question," Luna said firmly. Flash swallowed and could only give a mute, dumbfounded nod at first.

Then his gums launched off once again, flapping and flying as they went. "In fact I really really like pregnant women like you would not believe but isn't the father of your baby—"

Luna lifted two fingers and pressed them against his lips to silence him again. "He's not here right now, and I always make sure to hide the evidence," she answered, a hint of a smirk on her face as she lowered her hand.

"Y-you hide the evidence?" Flash croaked, brain scrambling to comprehend what was going on.

Luna nodded once, tilting her head slightly. "How about this: I'll let this slide…" Okay, yep, that was a genuine smile on her face now, and it widened with each word leaving her mouth.

Then Flash registered the whole 'I'll let this slide' thing and a flag raised itself high in his head. "Y-you will?" he stammered out. Another nod answered him without hesitation.

"That said, you did walk in… so how about this," Luna began straightening her back just an eentsy bit. Flash waited for her to continue, but his breath hitched in his throat as he felt a hand coming to rest on his knee. "You do me a favor, and we'll never speak of this again?"

"A-a favor?" Flash stammered, brain spinning as it struggled to comprehend her meaning.

"If you can help me, because you see…" Luna stood up, and grabbed Flash's hand as she rose to pull him with her. "I'm having a bit of a dry spell." Flash managed to turn from beet red to a shade of crimson seen only on superheated metal in that moment, though he managed to suppress the urge to jump back and yelp in surprise. He really did not need a concussion on top of everything else right now.

Still, he did feel the pressing need to ask, "A dry spell?"

Luna nodded and moved to lean against a wall, thankfully one that had a bench sitting next to it. She sat down and spread her legs with a blush, showing Flash a little more than he'd already bargained for. She was dripping already, and Flash wasn't sure whether it was the shower—which he now noticed had been turned off at some point, as the warm mist didn't linger as heavily—or if that was plain arousal announcing its presence.

Flash felt his blood rushing to his loins. "You know…" he began, contemplating what was currently happening. "You kinda looked better wet. Wanna move to the shower?"

Luna's smirk widened. She stood up and walked to the stall she was in before her privacy had been intruded upon. "I thought you'd never ask," she muttered. She turned the knobs, getting a spray of water at point-blank range, and waited for the blast to heat up before waving Flash over with a hand. Flash took the invitation and strode right over to the stall, taking a moment to appreciate the hot water raining on his head as he entered. It almost melted the dull ache from his crash landing, it was hitting in just the right spots!

Wasn't quite heavenly, but it came pretty close to it. It didn't stop him from noticing Luna closing the distance, or leaning towards him, however. He looked up, only enough to stare into her eyes, which glimmered warmly. The mist started rolling off the shower spray, shrouding the two of them in a gentle embrace. This time, though, he felt he was ready. Seizing the chance, he gave Luna a firm kiss that lasted for a few seconds before parting from her lips to kiss her along her neck. She gave a low hum of appreciation, the sound evolving into a soft moan as he started pecking his way past her engorged breasts, though not without leaving them two kisses beforehand. The closer he got to his prize, the wider she spread her legs, careful to avoid slipping and losing balance.

And on the way down, peppering her with kisses as he went, Flash could feel his cock hardening. However, its needs could be postponed for the moment, as Luna had offered him something—crazy as it was, he wasn't going to back out of it. No way in hell would he back out now. Once he was in front of her moistened vulva, he gave it a long teasing lick, and Luna gasped sharply with her back arching over him.

"Ffuuuu…" Luna moaned as she felt another lick sliding up and down her sex, Flash humming in appreciation as he started his ministrations. She trembled, one hand against a wall for balance in case she were to fall, and the other coming to rest on the top of his head as his arms wrapped around her thighs. Encouraged, he started to lick more, humming as the hand on his head ruffled his hair.

It wasn't long before she started to buck her hips, but held as she was, she found enough restraint to keep the jerking light and minimal. She kept ruffling his hair, moaning softly as he sped up his licking a little more. For a few seconds, he kept up his strokes in time with her rubbing, before he shifted to a gentle nibbling of her clit. Luna bucked a little harder, panting slightly, the sound only driving him to pleasure her more.

He worked at her sex, nibbling and licking it gently, but with need. He kept it up, slowly driving Luna to buck more and more as encouragement. When she was shaking slightly, he pulled back and glanced up to shoot her a glistening smile. "You want more?" he asked.

Luna gave a shaky, but nonetheless firm nod. "P-please finish me off," she begged. Flash nodded back and went back in to suckle gingerly at her quivering sex. Luna started bucking again, panting faster and faster as she felt her climax rapidly approaching. Flash rubbed her thighs with his hands, shoving his tongue into her snatch and licking at her innermost walls to further sate her need.

Nails started digging into his scalp. Her hand started pushing him against her groin, itself trembling with need as she tried to egg him on into pushing her over the edge. Muted pleas left her mouth as her hips bucked harder and faster, legs quivering as her need was slowly being realized. Flash moaned at this, and continued to eat her out, rubbing her thighs and keeping his hold on her for stability. Alternating between sucking and licking, he could already feel the first tell-tale trickling of her flowing juices dribbling down his chin, mixing with the hot water still raining down upon them both.

He kept eating her out as, with a cry, she came and came hard as he started to trace his tongue along her vulva. Her juices got all over his face, but the shower spray swept much of it off as he licked her clean, helping her ride it out as, as fast as it had come, it had petered itself out. Luna, panting, waited until he let go and smirked up at her before kneeling in front of him, going slowly to avoid slipping once more.

She opened her mouth to say something when he once again caught her by surprise. His head went between her tits, and she felt his stiffened cock rubbing her engorged stomach eagerly. Luna moaned as she felt his tongue licking her chest, alternating between each breast, and his cock barely twitching as it moved in tandem with his tongue. Flash's hands, ever so gently, grabbed the sides of her mammaries, rubbing them and moving them from side to side as he went to work.

Though, she gasped sharply when he got a bit too rough for her liking. He pulled back, frowning. "You okay?" he asked.

"J-just tender," Luna replied, sighing as the pain faded. "C-could you lay down for me?" Curious, Flash obliged, and gasped as she straddled his hips and placed one hand on his cock. Slowly, she inserted and lowered herself upon him until she was hilted on him, humming in appreciation as her dampened sex enveloped him eagerly. Flash thrusted up after a few seconds, already eager to start humping. A hand to his chest stopped him.

"Ah-ah, not so r-rough now," Luna reminded him, lifting her hand to rub her stomach for emphasis. Flash nodded and sighed in contentment, grinning like a fool as slowly her hips lifted and came down again. Luna repeated the maneuver a few times, slickening Flash's cock with leftover juices and shower-water as she got the hang of the motion. Flash grunted and moaned as, slowly, she began to ride him out with careful, yet pleasing smoothness. She went to the maximum depth her body would allow, panting and moaning as pleasure began to build up once again.

Flash was content to let her ride him. The sensation was heavenly; Luna's belly smacked into his lightly as she gyrated on his cock, her warm and silky walls grasping him tight enough to make him throb. She was wet enough that she could have rode him with the water turned off, and it wouldn't have made much difference, but it made her pull on him as she started to pick up speed.

He moved his hands to her hips and grasped firmly as she kept bouncing upon him, panting and grunting and thrusting lightly whenever he could to give her that much more pleasure. Luna moaned, smiling as she felt him throb again and again. She paused to wiggle her hips against his for a moment, caressing his cock with her walls through the motion, moaning before gently lifting off, turning around, and laying on her side next to him.

Flash grinned and turned so his chest met her back, and promptly re-inserted his cock into that warm, inviting hole before thrusting eagerly. He grasped her hips firmly, licking at Luna's earlobe as he started thrusting faster and faster. He grinned as she moaned once more, grunting as he started to hit home again and again.

Each thrust ignited fires in his nerves, each one clouded his mind with wave after wave of pleasure, each one drove him that much closer to release. He licked at the nape of Luna's neck as she loudly, lewdly moaned, feeling her walls clench on him and begging him for release. He started thrusting as fast as he could, grunting with each smack, licking throughout as he throbbed more and more until a haze erupted within his head.

He heard a squelch and felt his own seed spilling within Luna, and felt her quivering as she came again. A few weakened thrusts after, and both were still, panting on the shower floor. For a while, neither of them moved as the shower spray washed away sweat and cum with equal measure.

Then, sluggishly, Flash pulled away and stood up to start washing himself. He helped Luna up to stand as well, and both cleansed themselves in silence. He could swear she looked at him with something akin to fondness sparkling in her eyes, and he returned it with a smile.

As they stood there washing, they made eye contact. Luna simply said, "I hope you enjoyed your early graduation gift."

Flash nodded. Short as it was, he couldn't help but want more. However, he was spent, and needed to get home ASAP. "I did, Vice-Principal. I did," he replied. The both of them shared a laugh, and in silence they continued.
