Two siblings are forced into a tight, awkward situation. Things somehow become less awkward, but more "heated".

As it turns out, traveling is hard. Storm Cloud dislikes the lodging she and her brother, Lightning Bolt, were forced into, but it stirs something in her. She acts on an impulse she thought she'd never act on. Is it something in the air? Or was this just bound to happen anyway?

The Whole Thing

“Any hour now, Bolt; it’s not like we have an early day tomorrow or anything…!”

Storm Cloud paused for a few seconds, gently twitching her tawny ears back and forth in anticipation of her brother’s reply. For one reason or another, it didn’t seem to be forthcoming, so the alicorn filly settled for a sigh and a flop back into the pile of patchy purple pillows behind her.

This was pretty typical of him. First he’d insist on showering first before bed, then he’d ignore any requests to hurry the heck up she tried to inevitably make to him. ‘Oh, sorry Storm,’ he’d say, rubbing the back of his neck and looking side to side as though he had an audience; ‘the water was too loud.’ Okay, sure, maybe sometimes it was...but here, she couldn’t even hear anything more than a light drizzling from the bathroom. The water pressure was...well, ‘lacking’ was putting it gently. And, to top it all off, the faded blood-red walls weren’t even soundproof. What kind of ‘love hotel’ had rooms that weren’t even soundproof? This one, apparently; not only was basically every normal, not...sex-related hotel in Las Pegasus booked tonight thanks to some concert or whatever, but somehow they’d landed in the one establishment that had only one star for its rating. If the city weren’t up in the clouds, she’d surely have been looking under the covers for bugs and other unwelcome guests.

But as the water pittered on and the moonlight filtered gently into their room, Storm felt her annoyance fade. As much of a doof as Lightning Bolt was sometimes...it wasn’t really his fault, and neither were most of the things she wasn’t exactly happy with. He couldn’t control the slightly-itchy bedspread, the flickering light-pink lights, or how much soundproofing their walls had. It was just that sometimes…she wished he’d get out of the shower a heck of a lot quicker than he did. She had plenty of travel dirt to wash out of her mane, too; it’d gone from yellow to gold over the course of the last 12 hours. Not that that was an overly big problem...but it was the little things that counted. Such as the weird sensation of warmth and need coming from somewhere between her legs. She knew exactly what it was...but didn’t even dream of entertaining that need for the moment. With her luck, Bolt would come out and catch her in the act. She just settled for crossing her hind legs and digging her head back into the not-too-comfortable pillows, waiting as patiently as she could for her turn in the shower.

Thump

“‘bout time!” she called, sitting up and glancing towards the bathroom before realizing...the water was still running. “What the—”

Thump...thump...thump thump thump

Storm didn’t know whether to roll her eyes or blush and pretend like she didn’t hear that, even as her wings decided for her by springing out from behind her. Ordinarily a few thumps in the night wouldn’t have even meant anything, but in a love hotel, and with the vibrations from the thumping sinking ever so slightly into the mattress beneath her...she knew exactly what that sound was, and her mind was running with ideas before she could even stop it. The thumping kept going for minutes at a time, slowly jolting ideas into her head. What if Bolt had heard it too? What if he was getting out of the shower, and...and he was going to ask her about what it was, and then she’d feel so, so weird and—

A squeak escaped her. “But Lightning...” she murmured to herself, a bright blush blooming across her cheeks as her wings relaxed back behind her again, and lewd thoughts blinked through her mind. “I-it’s not...that I mind it...that much.”

No response. Of course there wasn’t, Bolt wasn’t out of the shower yet, even though now the water wasn’t running anymore. She glanced over at the bathroom door, just to make sure...

...and saw it slowly creak open.

Gulp.

“Bolt! You’re done!” Storm said, rubbing her hoof against her eyes and trying to not let him see too much of her increasingly-hot face. “Any water left for me, goofball?”

“Yeah, of course.” Lightning Bolt stood before her, water dripping from his fur onto the carpet...but at least he had the decency to be toweling himself off while he paused, and cocked an ear towards the wall. Much to Storm’s surprise, she saw a hint of a blush creep into his chestnut-brown cheeks before his big, piercing, electric-blue eyes swung back to hers, sending a chill down her spine as she instantly pictured him sprawled out on the bed, inviting her closer—no, absolutely not, Stormie, don’t get any ideas! Come to think of it...why was this getting to her so much? Normally, she didn’t even think of him in that way. But something about the rhythmic thumping and pounding seemed to be...stirring something inside her, something that was growing less and less timid by the second.

“Uh...so that’s...something,” Bolt observed, ruffling his feathers as he patted his horn dry. “You uh...need any earplugs? I think I’ve got some spare in my bag…”

“No, it’s fine,” Storm interjected, just a little bit louder than she would have liked. Almost automatically, her earlier snippet of self-interaction presented itself to her mind, and she found her mouth repeating her words, but actually to her brother this time: “It’s not...I don’t mind it that much…”

Bolt didn’t reply immediately, just rubbed a slightly-more-disheveled-than-usual hoof through his mane and scrunched up his muzzle with a slight smile. “Heh. You don't have to be tough for me, Storm,” he eventually said, stepping closer and tossing the towel aside. Storm did her best to not look between his hind legs, an urge she normally didn’t even consider, let alone have to fight against. “Nothing wrong with wanting earplugs."

...but of course, Bolt didn't stop there. Instead, he placed a hoof gently on her shoulder, and gave her a slow, quiet half-grin. Storm swallowed, looking up at him with the best vacant expression she could manage. She’d never noticed more than in a passing glance before, but he was kinda handsome...when he wasn’t being a forgetful doofus, at least. He stood there for a few seconds longer, and even though she didn’t even remember initiating the movement, she found herself leaning towards him. So when he finally stepped forward, she was ready to meet him halfway. What the heck was even happening...were they really about to just...do ‘it’? Spurred on by the random thumping in a run-down love hotel in Las Pegasus? Were they—

“Woah, hey there—” Bolt’s words cut into the moment as he stumbled back, his cheeks definitely red now. “Sis, I uh...you...did you mean to do that, or…?”

“I...” Her voice came out as a squeak, but Storm knew exactly what he was asking. She just needed a few more seconds to figure out what exactly she was going to say. “Uh, y-yeah...” Oh, and maybe five seconds to accept that her wings were splayed out behind her yet again. “I-I did mean to do that.”

"Oh." Bolt licked his lips, looking up to the ceiling for a few seconds. Storm was just a little bit annoyed now; wasn't he going to say something? If there was one thing she hated more than him taking long showers, it was his tendency to make awkward silences last forever (even if she’d caused this one, for once). Her wings twitched despite her trying to make them relax, and her blush was moving even further down her face as the seconds passed.

"You uh..." Bolt started again, "I just...I never thought you were interested in…or that we could..."

A bit of an awkward silence followed, broken only by the distant thumping. "...I never thought you were interested in smaller ponies," Storm said quietly, giving her first full smile since he first exited the shower.

"Smaller? Really?" Bolt didn’t seem at all sure what to make of that, and locked eyes with his sister. She nodded, and promptly found her hoof slipping up towards him and grabbing his mane. Her wings were actually pushing themselves behind her head, they were so nervous. Worrying about whether or not this was really happening. But as far as her rapidly-beating heart and gently-squeezing thighs could tell...it definitely was.

"...uh-huh.” Almost from nowhere, the young alicorn could feel her confidence growing, feeding from the need between her legs. She pulled him in a bit closer, and leaned towards his ear. “Or younger ones, if you prefer.”

“I don’t know about p-prefer,” Bolt stammered in response, seemingly unable to make eye contact. “It’s just that...you’re my little sis, and usually I just...I’m supposed to take care of you, make sure your needs are met, and...that stuff.”

“You would be taking care of me, though,” Storm purred, scooting back onto the mattress, and tugging Bolt along with her magic as she did so; he offered nothing more than token resistance, to her delight. “I...think I’m in Estrus or whatever that one book you gave me said happens when I’m old enough. And I think I need...to have some fun.” She’d only ever (covertly) read about this sort of situation when Bolt wasn’t looking, but to be on the top end now felt...great. Her wings had floated back down now, stiffly spreading themselves out behind her, and even her horn now gently sparkled with residual excitement.

Bolt still seemed to be unable to meet her eyes, even though Storm could clearly see his...pride and joy beginning to poke out from between his legs. So she thought for a quick moment, before grinning, priming her horn with magical energy as she felt the dampness between her legs grow.

“Alright, dork, lie down on your back,” she teased, before making him do it herself with a firm, but not forceful, magical shove. In turn, she pulled herself up, clambering onto all fours before planting herself over one of his spread hind legs, her eyes fixed on his stiffening shaft on full display. She could see him looking at her, brows knit together almost as if he were worried...but if he didn’t want any of this, he wasn’t saying as much, so she continued.

“I know you talk a big game, but that I’m the first gal who’s gonna...do stuff with you,” Storm said, gently lowering her torso onto his leg. She shivered a bit as she felt her seemingly hypersensitive privates brush slightly against his bulky muscles...exactly according to plan. “So if you really can’t bear the thought of helping your li’l sis out with her needs...how about you close your eyes and pretend it’s somepony else?”

“C-close my... Storm, I don’t think that’s gonna work!” Storm could see a bit of sweat forming on Bolt’s brow. Yet despite his misgivings...he wasn’t exactly stopping her, either. “I can’t just close my eyes and pretend it’s not you!”

“Sure you can! Here, I’ll help...” Storm closed her eyes in concentration, and a small ball of magical yellow energy began to build at the tip of her horn. When she felt that it was big enough, she opened her eyes and molded it carefully into a sheet, before wrapping it tightly around his eyes, and ‘tying’ it behind his head, making it opaque with another quick thought.

“There, see?” She said, before snickering. “Well, maybe not. But now, you can just pretend I’m anypony you want. Even if it is still me…~”

“But—…”

Storm grinned to herself as her brother stopped mid-complaint. As it turned out, moving forward to rub her nose against his large, vertically-towering cock was an effective way to get him to shut up for once. Now that she was close, she realized how...huge it was. She didn’t even think it’d fit her. But there was still a way to have fun; with a low murr, the alicorn filly raised her head up, and locked her hind legs around one of her brother’s, grinding in deeply against his firm musculature. Her wings flapped for stability as she tossed her head back and let out a long moan, coming in much louder than even the close-by thumping from next door. This somehow felt way better than just her hoof...and she had a hunch that what she was about to do to Bolt was going to feel better than his hoof, too.

Storm licked her lips, and stared down at her brother’s throbbing cock...before opening her mouth, and shoving it into her mouth, grinding her hips again as she did so.

“Fffffuck, S-Stormy...”

The filly’s eyes widened as her brother’s hips bucked upwards, sending more of his hot, pulsing, musky, yet delicious length deeper into her mouth, stretching it wide. Storm felt a wave of blazing heat wash across her face as her brother let out a low satisfied grumble, almost inaudible beneath the wet slurping sounds she found herself making. She’d seen and imagined what a real cock would be like for sure, but this...sucking on it was beyond anything she’d ever imagined. The damp, musky aroma in her nostrils was making her body feel even more tingly. She was thrusting down automatically now, grinding her wet pussy against Bolt’s leg, sending spikes of simultaneous pleasure and arousal up her back and straight into her brain.

Her wings were pointing directly towards Bolt’s head now, the soft feathers whispering softly with each little buck of her hips; little by little she was getting closer, and closer...and it felt like he was too. Each time she moved down, cramming some more of that husky, girthy cock down her tight little throat—even making her briefly hold her breath on each stroke—she could feel him thrusting back harder and squirming back, his cock twitching as her tongue swirled around his shaft. She remembered reading that stallions liked that sort of thing, and Bolt seemed to be no exception to that for sure. His leg was even twitching in time to her grinding, which had her moaning growing shriller as her pleasure grew, filling her head with clouds and horny heat. Each bump brought her closer and closer to the inevitable peak. She didn’t even care anymore how much she was drooling as she hilted as much of his meaty cock into her mouth as she could; all she cared about was feeling good, and making him feel good. She was almost there, in fact, when she felt one of his forelegs rest itself gently on her head.

“S-sis...!” Bolt groaned quietly, his wings fluttering as his thrusting intensified. “I think I’m gonna—!”

Without warning, Bolt’s hoof suddenly pressed down hard, shoving Storm’s head all the way down to the base of her brother’s thick, meaty shaft, grinding her nose against the top of his pelvis. The sudden increase in force, nearby heavy-smelling pheromones, and the hot spurts of cum that began shooting deep into her body were too much, and very soon, Storm found herself cumming as well. She seemed completely unable to breathe with how much of Bolt’s length was lodged in her throat, but that hardly mattered; all that mattered was the endless pleasure and relief that surrounded her, cascading in a mix of heat, quivering, and lustful whining as she squirted out some juices behind her. The cum just didn’t seem to stop coming from either of them, and Bolt’s hoof kept her firmly planted in his crotch, unable to breathe, her face turning redder and redder, her struggles to lift her head growing more desperate as the air in her lungs grew stale.

“Mmphg! Mhhppmmmhg!” she squealed, shuddering as her hips suddenly ground down even harder against his leg, an instinctual decision that brought her orgasm back to the forefront for one last hurrah; spurt, spurt, struggle, push, shiver, whine—

And then she was free, breathing in huge gulps that she would have laughed at if she were able, her breathing ragged and her eyes wet. A few wispy strands of mane dangled in front of her slowly-refocusing vision, which eventually sharpened into her brother’s big cock, completely glazed with both her fluids and his, glistening in the low light of the room.

“...wow.” Bolt was the first to speak, a shy grin spreading across his face. “You...you did amazing there, Storm. I didn’t know you could even...”

Storm couldn’t hold back a smile, finding her brother’s flowery praise rather endearing...even considering its subject matter. “Neither did I,” she teased, idly rubbing against his leg once more, enjoying the subtle sensations of pleasure that followed. “But uh...I’m glad we got to.”

“Hey, can you—“

“Oh, right.” Storm giggled as she undid the spell keeping her brother blindfolded. As the magic sparkled and faded away, Storm scooted forward, straddling herself across Bolt’s midsection, just in front of his slowly-softening stallionhood. “Maybe we should...do this again sometime?~”

“A-actually, yeah!” Bolt’s eyes brightened, and he nodded. “Just...um...not now. I...need to rest a bit.”

“Oh, that’s fine.” Storm Cloud winked as she rolled off her brother and onto the floor in one smooth motion, landing on all fours. “I’ve still gotta shower, and we have an early day tomorrow and all that. But if you wanna join me there, I wouldn’t say no to round two...” To emphasize her point, the little filly wiggled her rump towards her brother while raising her tail.

“C-come on, now, sis!” Bolt’s ears were tinting red, but he chuckled just the same. “I’ve gotta, uh...get ready for bed.”

“Right-o.” Storm giggled as she made her way towards the bathroom door. “See you in a bit, then. Whether it’s while I’m wet or not~”

Storm didn’t even have to look back during her walk to the bathroom to know that her brother’s eyes were glued to her flank the entire way there. With any luck, she hoped he’d hop in the shower with her after a little bit of rest, and then they’d take care of that niggling little desire already beginning to return to her filly parts. Maybe they’d finally try to fit his cock in her pussy...she couldn’t wait to feel what that would be like, being stretched around something so firm, wide, and long...if it even fit at all, that was.

But there was only one way to find out...
