Rearrange-oh no!

Twilight smelled smoke inside the house.

"THE HAY FRIES!"

Twilight Sparkle and her brother rushed into the kitchen to put out the flames in the oven, saving the kitchen. But when it was all over, both were covered in sooty ash from head to hoof. Shining took the tray of charred fries and dumped them in the trash.

"What did those poor hay fries ever do to you?" he asked.

"It was an accident."

"That was the last of the food," Shining said solemnly, "and you incinerated it."

"It was an accident!" she defended. They both sat at the table.

"So what now?" he asked.

"Now, I'm ready for bed." Twilight said. "But first I'm going to need a shower." She motioned to herself. "And you too." He looked at his own sooty fur.

"I guess so. Do you want to go first?" he asked, offering the one shower in the house.

"Nah, just, let me rest here for a while. It's... been a day."

"Yeah, no kidding." Shining headed upstairs to shower.

When he reached the bathroom he had a familiar sensation. He needed to pee. On instinct, he walked over to the toilet and reared up, reaching down to aim his- "Oh... right." For a minute, Shining just stood there. A bit baffled, looking down at his, or rather, his sister's lavender legs under him, unsure of what to do. It seemed straightforward enough. But he didn't want there to be any more incidents. He opened the door and called downstairs. "Twilie?"

"What is it?" she yelled back up.

"I need to pee."

"That's great," she answered. She could feel a headache coming on.

"Um, how do I, you know ... do it?" he asked. Twilight groaned.

"What? There's no secret to it. You just sit there and... let it happen," she said, explaining the seemingly trivial concept to an adult. It was quiet for a minute.

"...okay." Shining was about to close the door when Twilight jumped up from the table and yelled.

"And make sure you wipe FRONT TO BACK! I don't want to get my lower half back with an infection!"

"Okay!" Shining closed the door again and walked back over to the toilet. He just stood there, planning his strategy. He didn't have any concrete memories of being potty trained, but he imagined it must have been something similar to this. "Fuck it." Not wanting to admit defeat to Twilight, he flushed the empty toilet, turned on the shower, and stepped in with a full bladder. It wouldn't be the first time he'd done it in the shower. Well, this would be his first time doing it as a mare.

And that warranted investigation!

Shining levitated the hoof mirror from the counter and held it under him. The toilet was a far smaller target than the tub, and he wanted to make sure that he knew where it was coming from, and at what angle it was aiming. He lifted his tail and looked in the mirror. Suddenly he became acutely aware that he was closely examining his sister's genitals. His stomach did a quick flop, like when a carnival ride did a sudden drop. But the feeling passed in lieu of his pressing need to urinate. He shook it off and proceeded to put a free hoof to his folds, spreading them.

It was a strange sensation for him, having a vagina. Hell, a gentle breeze felt different now. And now him putting his hooves on himself. He felt a somewhat similar feeling, a tingling in his belly as he touched his sensitive folds. He adjusted the mirror. Ponies didn't usually wear clothes, and tails, for the most part, hid their modesty. And it was just common courtesy to not look. Despite this, Shining Armor, whom hadn't yet been intimate with a mare, hadn't ever really gotten a good look at the other gender's defining features up close.

But there it was in front of him. Or rather, behind him. Completely at the mercy of his hooves as he washed up with soap. He was free to touch it all he wanted. He spread the lips, moved them this way and that. Touched here, there, everywhere. He felt a pang in his kidneys. He'd held it long enough. He took a deep breath and released.

As far as visceral sensations, it wasn't all that different. His stream more or less went predictably straight down where he squatted, splashing off of the mirror and onto his legs. The feeling of emptying his bladder was the same palpable relief he was used to. And the running water of the shower washed away the mess. He finished cleaning the rest of himself, scrubbing with soap and shampooing his mane and tail. But he was fixated with his new 'feature', probing at it with his hoof. He wondered if the narrow, cylindrical shampoo bottle would fit in it. He levitated it under him and pressed it to the small opening.

KNOCK KNOCK KNOCK

"Hey! Are you going to use ALL of the hot water!?" Twilight shouted.

"Okay! okay!" Shining quickly put the bottle down and finished rinsing. He turned off the water and stepped out, toweling off. Before he could even finish, Twilight opened the door.

"Hey!" Shining said, covering himself.

"What? Are you afraid that I'll see my own privates? I was tired of waiting," she said.

"Alright, alright. Sheesh." Shining hastily finished and hung up the towel, leaving the bathroom and closing the door behind him.

Twilight's shower was far less eventful than Shining's. Contrary to her usual, curious self, tonight she was as brief and practical in the shower as she could, focusing on cleaning her mane and fur of the soot from the fire. Her lower half was not nearly as dirty. And she wasn't nearly as keen to be putting her hooves all over her brother's flanks, even if they were attached to her for tonight. The running water and suds were enough to rinse it clean. And that was good enough for her, turning off the water and toweling dry before going to bed for an early night.

"AAAAAAHHHHHH!!!"

The next morning, Shining awoke to the sound of his sister screaming. The clock on his nightstand said 5:59 am. He jumped from his bed and ran down the hall.

"AAAAAAAAAHHHH!!!"

Her screaming continued. Shining ran to her room.

"What is it!? What's wrong!?" He yelled, expecting the worst. Twilight was sitting in her bed, still under the covers, lifting them and looking under, presumably at herself.

"IT'S- IT'S OUT!"

"What!?" Shining rubbed his eyes in the doorway, even with his heart pumping adrenaline from the shock of the rude awakening, he was still barely awake.

"IT'S OUT!" she screamed again. "MY- YOUR- IT'S OUT!" She looked away from herself, clenching her eyes. "IT'S ON! IT'S UP! IT'S OUT!"

"What the fu- oh, for pony's sake." Shining rubbed his face in disbelief. Twilight was having her first encounter with morning wood. "Stop screaming. It's just morning wood."

"What?" Twilight asked, still shaken.

"Morning wood. It's a-" he used the clinical term with her, "It's an erection that you have when you first wake up. It's normal."

"How do I make it go away!?" Twilight pleaded.

"What? You don't do anything. Ignore it. It'll go away on it's own."

"When? How soon!?" she asked.

"I don't frigging know! I never timed it!" He yelled. "It's too early for this crap! Go back to sleep." Shining walked back to his room and closed the door. He cursed into his pillow. He didn't remember the first time he'd ever had morning wood. But he sure as hell didn't scream and wake up the whole damn house. The clock on his nightstand said 6:01 am. He pulled the covers over his head.

Twilight sat in her own bed. Her alarm had gone off, waking her for school. It was a Friday after all. The clock didn't know it was a holiday weekend. But when she lifted the covers and saw... that, she freaked out. She was calm now. Or at least, calmer. The blankets covered it. But she could still see it bulging through the blankets. Menacingly.

Despite living with her father and brother most of her life, and the fact the ponies normally didn't wear clothes, she'd never a penis before. Balls and sheath, sure. But that was nothing compared to... this. And sure, she'd seen a penis before in anatomy books. But the reality of it... She touched the bulge through the blankets, causing it to bob and send tingles of pleasure through her body. "Eep!" She squeaked involuntarily. She grabbed her blankets and lifted them once more, peeking underneath. There it was, staring back a her like a snake, poised to strike. Shining's words echoed in her mind.

"You don't do anything. Ignore it. It'll go away on it's own."

"How do I ignore this?" Twilight asked the empty room. Twilight dropped the blankets again, covering it. She tried to think of anything else. Homework. History. Math. Botany. Trixie's supple, azure flank, begging for her to stick in her long, hard, throbbing- wait, NO!

"Errrrggghhh!" Twilight shook her head and grit her teeth. She threw off the covers and got out of bed, marching down the hallway. It slapped against her belly with each step. She threw open the bedroom door. "Shining!" The clock on his nightstand said 6:03am. Shining didn't even roll over to look at her.

"Twilight, I'm going to turn around now. And you had better be on fire. You're standing there in flames, and the ONLY pony who can put you out, is ME! Because that is the only CONCEIVABLE REASON, that you would wake me up like this!"

He was not a morning pony.

"Shining, come on! This is serious!" she whined. Shining clenched his eyes and counted to ten in his head.

"What. Is. it?" he asked, as he sat up, resigning to the fact that he wouldn't be getting back to sleep.

"It's still... look!" She raised her leg. Her condition was obvious.

"I told you. Just ignore it."

"I can't! I tried! It's just, it's all I can think about! My every thought is bent on it! I can't think straight. I just- I just-" Twilight didn't care for using the word, but she could think of no other word that could so completely encapsulate her feelings. "I just want to... FUCK something! I don't even care what!"

"HA!" Shining laughed. "Welcome to life as a stallion! I'd say 'get used to it' but lucky for you, you won't have to. So don't expect any sympathy from me. I have to deal with that every day."

"Really? I mean, is it really this bad for you?"

"Well, not for me. Not anymore. I got used to it and learned to control it a long time ago. But it's new for you, so I can understand. Just wait until you have a couple of little colts of your own someday and they start humping the furniture for no reason. It doesn't get them anywhere, but that's what it's like. They just want to 'fuck something'. Even if they don't understand what they're doing or feeling."

"So?" she asked.

"So what?"

"So how do you not?"

"How do I not, WHAT?"

"How do you not... you know, not just pounce the nearest mare and.... fff-fuck her?"

"The threat of prison is a good start."

"Shining..."

"Twilight, I've had a penis for a long time, and I've never seriously felt rocked by the urge to rape somepony."

"I'm not used to this!"

"Alright, alright! Just go- jack off then. That usually clears it up." Shining finally said.

"Jack off?"

"Masturbate! Sheesh, do I have to spell it out for you?"

"Oh." Twilight just stood there in his doorway. The clock on his nightstand just turned 6:05 am. "How?"

"Oh for fuck sake..."

"Shining!"

"No. No! I am not having this discussion with my sister!" He pulled the pillow over his head.

"What? Did you just know what to do with it the first time it happened to you? Did you just know how to- masturbate?"

"No, of course not." Shining groaned from under the pillow. "I had to figure it out on my own."

"Don't you wish that somepony had explained the best technique to you so you could have found relief right away?" she asked. Shining sat up and threw his pillow past her. Not at her in anger. Past her in frustration.

"No. Because that would have been freaking weird! Just like this! Even if you were actually my little brother, I still wouldn't tell him how to... jack off because it would be freaking weird explaining that to a colt!"

"Everything about this is weird!" Twilight took a step back, and tried to cool down. She tried to collect her thoughts. "We're out of food." Twilight said, grasping what clear thoughts she could. "I need to go to the market. But I can't go like... this." Shining was forced to look at his own equipment, attached to her.

"You can't go out at all," he said.

"I can with a dress! You can't wear a dress and cover up your back half. But I can. But not like..." Her penis bobbed against her belly again. Twilight groaned in agony. "Ngggh. Not like this!" She looked at him with desperate, pleading eyes. He glanced out the window. Celestia's sun wouldn't even be up for another forty five minutes. Surely there was a special place in the deepest realm of Tartarus for the pony that invented the alarm clock. He rubbed his eyes, and looked back at his sister in his doorway. Her 'condition' had not improved. And she was not going to take no for an answer. This was actually happening. Shining sighed and formed a plan.

"Okay. I will help you. First, go to your room. I will be there in two minutes. Not another word until then," he said curtly.

"But-"

"Not. Another. Word." He pointed his hoof, dismissing her. Twilight turned and returned to her room as she was told. Shining rubbed his temples and got to his hooves. He made his way to the bathroom and opened the cabinet, pouring a small cap-full of potion for the headache he could feel brewing. After drinking that, he stepped in front of the toilet and reached down to aim his-

"Oh. Right."

There's no secret to it. You just sit there and... let it happen

Twilight's words echoed in his mind. He turned around and sat, relaxing his tension. Just as she promised, it came forth, a stream more or less straight down.

"Yup. Weird. This is definitely weird," he muttered to himself. He found it new and strange that he had to wipe after peeing, but it was absolutely necessary, with the change in anatomy. It proved tricky and he gained a new appreciation for why mares took so long using the rest room. Once he was cleaned, he couldn't help but touch himself as he looked down at it. He could smell himself on his hoof. The musk of a mare's sex.

His curiosities were wrenched short at the realization that he was actually smelling his sister's marehood. With his promised two minutes up, he flushed and washed his hooves. He grabbed a bottle from the shower shelf and walked to Twilight's bedroom. Twilight was waiting patiently on the bed, her blankets covering her lower half.

"Here," he said to her, giving her the bottle of Neighbelline fur & mane conditioner. "Just put some of this on your hooves, and... rub it up and down until you cum. Then you should be all set." He turned to leave her to her... business. Just as he reached the door, Twilight called out to him.

"Wait!" she cried. Shining turned back and looked at her.

"Twilie, I really can't be any more specific than that. It really is that simple. Do the basic motion, and figure out what feels good for you. I'll be downstairs..." drinking bleach "doing something else."

"No, that's not what I mean."

"Then what is it?"

"Can- can you do it?" she asked. Shining heard something snap. He hoped it was something he didn't need, like his neck, and not his sanity.

"Excuse me? Could you repeat that? I must have had something crazy in my ear. It sounded like you asked me to-"

"Do it for me?"

"Okay, short answer: No. Long answer: Noooooooooo!"

"Shining!"

"oooooooooooooooooooooooo!"

"Come on! Please! I just- I really- I really don't want to touch it!"

"oooooooooooooo." Shining caught his breath. "Twilie, it is..." he rationalized his own actions in his mind, "it is attached to you. So for right now, and until Trixie gets back, it's yours! It's your problem. And I'm not putting my hooves on those... parts, while they are attached to you." Twilight was on the verge of tears. Shining's mind raced, early as it was in the day. Twilight started to cry. If there was one thing that he couldn't stand to see, it was that.

"Alright Twilie, alright. But if we're going to do that, we're not doing it in here. Come on." He led her back into the bathroom. "Stand in the tub." He instructed her. "Now close your eyes." Twilight did as she was told, waiting for him to relieve her. Shining braced himself for want was about to happen-

and turned on the cold water, full blast. Twilight shrieked.

"GYAAAAAAAGHHHHHHH!" Shining held her in place with his magic under the icy water. Much of it splashed onto him from her flailing hooves. Shining kept up his hold on her while she kept screaming under to stream of cold water until he could see that it'd had the effect he was going for. After not too long, he shut off the water, bracing himself. Twilight came at him, ready to thrash him with her hooves. Each blow careened off of the shield that he'd put up, causing sparks to fly off and iridescent waves to ripple through it. She kept yelling at him, "You bastard! What the hay was that for!?"

"Look!" he motioned from behind his shield. Sure enough, the cold water and rush of adrenaline had caused an immediate retreat of 'little Shiny' back into its sheath. Twilight realized what he did, and relaxed. He levitated a towel over to her, waiting for her to dry off. "Okay, I'm going to lower my shield now," he said. Twilight gave him a swift punch to the jaw. "OW!"

"You deserve that!" Twilight said, stepping past him as he nursed his face. Twilight stopped just outside the bathroom door and looked back at him from the hallway. "Hey. Thanks."

"You're welcome," Shining groaned.

His headache had not improved.

The drama from the early morning had passed. The two of them sat at the kitchen table, going over the grocery list. The headache potion had finally cleared Shining of his cranial pain.

"It's just a few items to get us through the weekend," Shining said. "I don't think we need to triple check the list to make sure that we didn't miss anything when we double checked it."

"I just want to be sure," she said.

"Alright, fine. You ready to go?" he asked. Twilight checked the dress she was wearing. She hadn't expected a need for any kind of formal wear for the weekend, but luckily her closet still had a lot of her clothes that still fit. It did the job of covering most of her body. Her tail, or rather, his tail was short enough to be completely hidden beneath the opaque fabric. A set of closed-hoofed boots served to conceal her two-tone hooves. It was a bit much for a trip to the market, but not overly so to attract too much attention. Twilight was satisfied with her preparations.

"Yeah. I'm ready," she said. Twilight headed out, down the street to the market. Shining waved to her from the window before closing the blinds again. They were taking an awful risk, her leaving the house like this. But they weren't going to be able to go three days without food. Shining turned back to the room, settling on the couch. He looked over at the remaining magic box that started all of this trouble.

He had taken leave time from the Royal Guard to get away from stress and drama. He found himself regretting the decision, wishing he were still at the barracks. He needed to get back to normal before he had to report back on Monday. He'd never hear the end of it if they ever saw him like this. He imagined that all those job-well-done smacks on the flank would become more frequent. His tail would get pulled more. The lieutenant would be getting a lot of 'salutes' from the other stallions. They'd probably be lining up just to- Shining noticed that his tail was raising on its own.

"What the hay?" He tried to clear his mind of worry. Trixie would be back by Sunday with the other box, and everything would be back to normal. He tried to think of something else to occupy his mind. Anything else around the house to do, rather than just sit there and worry until Twilight got back from the market. He shifted his legs, causing his thighs to rub together. The tiny shivers of pleasure that resulted, did not help to keep his mind from the acute fact that he had a mare's lower half. Although it was clearly being delivered in a different package, it was a familiar itch. One that he was struggling not to give in to scratching.

A cold shower served to cease Twilight's problem. He totted upstairs to the bathroom, hoping it would do him the same. Thinking of her, he wondered if Twilight was fairing any better...

The way to the market was a familiar route for Twilight. She had taken it many times growing up in Canterlot. And in those years, the market in the commercial district had changed very little. It was a holiday Friday for the students of Celestia's School for Gifted Unicorns. But for the rest of the city, it was business as usual. The market was a flurry of activity. The stores that lined the main avenue had all manner of wares on display in the window. And outside on the walkways were stands selling goods of all kinds. The vendors in the median of the street made navigation tricky in the crowd.

The crowd was a mix of ponies of all sorts. Mostly Unicorns, but there were plenty of Pegasi and Earth ponies alike. There were a good number of stallions but, like the rest of Equestria, the population was mostly female. Mares, some mothers with their foals, and other fillies from her school that likewise had the school day off.

Luckily, Twilight had a short list of grocery items. And the food stalls were mercifully grouped together. Which was good because, while 'little Shiny' was safely hidden in its sheath, her scrotum still hung freely between her legs. It felt strange enough last night and this morning. But this was her first time walking around for an extended period with everything brushing against them. Her dress, her tail, her legs. It made focusing on the task at hoof a challenge.

And there was something new about the market itself that was different today. Or perhaps it was always there, and it was only now that she noticed it. It was the smell. Sure, there were all manner of fresh produce, aromatic bouquets of flowers, and fresh baked pastries. But beneath it all, there was something else, more subtle. It was the crowd itself, the mares, the musk. Their musk.

Twilight shuddered. She was familiar enough with her own feminine scent. And now that she had recognized it, she couldn't ignore it. It wasn't the dense, overbearingly pungent smell of a mare in heat. But it pervaded every part of the air. She couldn't get away from it. Her nostril involuntarily flared, drawing in more. She shook her head and checked the list again, trying to focus. She hastened her way through the avenue, getting the items she needed as efficiently as possible. Waiting in line for one of her last items, she shuffled her hooves impatiently, desperate to get out of there.

The mare in front of her was struggling with the basic concept of what type of produce she wanted to select, clearly having not used her own time at home, or on the way to the market, or at the market, or in the line, to have thought about this. No, only waiting until at the very last second to even begin to contemplate the arduous choice between Gala apples or Honey Crisp apples. Twilight hadn't the social fortitude to say anything as she waited.

Another pony, pushing a cart too high to see over, erred a bit too close in the crowd, bumping into Twilight. Twilight was already right behind the other mare. The contact knocked her forward into her, pushing her into her tail.

"Hey!" she said, looking back at Twilight.

"Sorry ladies," the other pony said, moving the cart away. The other mare in line could see what had happened and understood the contact was unintentional. Twilight blushed with embarrassment. She'd kept herself from making any direct contact with the mare's nethers. But the dock of her tail had been heavy with her strong scent, filling Twilight's nose. The effect was immediate. The tingle from earlier was charged with electricity running through her. She could feel herself stirring as blood pumped to her new appendage. She knew that she needed to leave. Like, right now.

She abandoned the apples on her list, trying to make a bee line out of the market place. The faster she tried to navigate, the more she exacerbated her 'little problem' with the friction of her movement. The shaft emerged from its sheath again, greeted by the fabric of her dress, stimulating her with each frantic step. Before long, the tip would be threatening to emerge from the waistline of her dress. If she tried to hike it up, her back half would be exposed. She started to panic. She needed to get off the street immediately. She ducked into one of the permanent storefronts.

"Greetings, welcome to the Canterlot Sal-"

"May I use your restroom please!?" Twilight asked urgently.

"I'm afraid our restroom is for paying customers only," the mare behind the counter said. Twilight frantically looked at the shelves. The Canterlot Salon. Her eyes landed on a familiar sight. Neighbelline fur & mane conditioner.

"That. I want that." She said, pointing at the bottle.

"Would you like that gift wra-"

"Nope. I'm all set!" Twilight all but threw her bits on the counter, throwing the bottle into her bag and dashing for the restroom, locking the door of a stall behind her. "Whew. Made it." she sighed, catching her breath as she leaned against the door. Her erection peeked out from the top of her skirt. "But now what am I going to do?"

Shining Armor stood in the bathroom and turned on the shower. He set the temperature to arctic, and took a few quick breaths, trying to psych himself up for the shock. He put his hoof in and felt the temperature and immediately chickened out, shaking the icy water from his hoof.

"Fuck that, with fries!" he said to himself. He turned the water off and rubbed his chin where Twilight had socked him earlier. "I guess I did deserve that." He looked at himself in the mirror. It was still the weirdest thing to see. From the side, it was like he was wearing purple pants, with his sister's Cutie Mark on them and her tail sticking out. He levitated the small hoof mirror over, lifting his tail again. He knew he shouldn't be doing this, looking at it like this. But he was mesmerized by it.

He lifted his leg up and down, and shifted his shapely hips, feeling it to move and change shape a little as he watched it in the mirror. The fact of whom it once belonged to became increasingly of less significance. He no longer thought of it as looking at his sister's pussy. Just that he was looking at a pussy. One that he could gawk at all he like without getting in trouble. He reached back and touched his lips, pulling it aside a bit. The purple of his marehood parted, revealing the pink inside. He could touch it all he wanted without reprisal. Explore it to his heart's content. It was practice, he justified to himself. If he was going to get with a mare someday, he ought to at least have a cursory knowledge of the terrain. What better way to learn than some hooves-on experience?

Shining felt himself getting flushed as manipulated his folds a bit more, spreading them apart. His neck strained, looking backwards and trying to get a closer look in the mirror. He could see the entrance to his vagina. His mind struggled with the absurdity of his mental pronouns. But it was attached to him. Even if he wasn't the original owner, it was just like he told Twilight about 'her' penis. It may be a rental. But it was attached to him. It was his vagina. He prodded at it a bit with his hoof. The opening seemed so small in the mirror.

The dimensions of his stallionhood were easy for him to recall. He wasn't huge. A bit above average perhaps, according to statistics and definitely not from whipping it out and comparing it to the other stallions' in the barracks shower room, because that definitely never happened.

He took the hair brush from the counter top and brought the handle to his entrance. The smooth, relatively-narrow handle slipped inside without too much difficulty. He slid it straight in and out with the steady rhythm of a metronome, as he imagined a penis would. It looked hot to watch, yet the feeling was lacking. Not that it felt bad. It was pleasant enough, the feeling of the slight pressure against his inner walls as it moved inside of him. But if the smutty magazines were anything to go by, he should by 'writhing and moaning in ecstasy, cumming uncontrollably' by now. But he found that the actions he was performing were astoundingly underwhelming.

Shining could only imagine how amazing it would feel to put his dick in a place like that. Warm, wet and tight, moving in and out just like he was moving the brush handle. But on this end... well, he began to understand the cliche of why mares seemed so disinterested in sex if this was what it was like. He pulled the handle out, leaving a wanton void. He'd managed to make a bit of a mess of himself, but he still felt the familiar urge to get off. He sighed and brought the brush to the sink to wash it. But before he did, he brought it to his nose, getting a good whiff of mare scent. He stuck out his tongue, licking the handle.

Shining Armor had a very diverse palate when it came to food. Canterlot was the hub of commerce for all of Equestria. Shining was grateful that his family was able to expose him to many different cultures in this way: customs, clothing, traditions, and styles. But most of all, the food. Cuisine from all over the land could be found here. Shining looked forward to trying new foods whenever his work in the Guard took him abroad. It was one of the biggest reasons why he joined.

But in all of his tasting experience, never had he had anything like this. His paltry descriptors fell pathetically short to the reality on his taste buds. Incomparable, there was simply nothing like it. It was a tangy flavor, tart and a tiny bit on the sour side, but in a good way like citrus, with just a hint of lavender. He'd never tasted a mare before. But he knew right away that it was something that he wanted to do again. "So why wait?" he decided, and licked the rest of the handle before tossing it into the sink to clean it.

His free hoof moved on it's own to his pussy once more, idly rubbing as he worked. His wetness dripped down his thighs as he dried the brush. He removed his hoof from himself at the realization of the mess he was making of his fur. He couldn't help but lick his hoof clean, cursing the fact that he couldn't get the sweet nectar straight from the source.

Shining realized that the room stank of his musk, and Twilight would be home soon. He decided that he'd better take that shower after all. He adjusted the temperature and turned the water on. "Start it off warm, and then turn it to cold," he decided, "ease into it". He stepped into the shower.

Twilight, in a different bathroom across town was still dealing with her own arousal. She pulled her dress up and sat on the toilet. She didn't have to pee. But even if she did, there was no way she would be able to like this. Her erection was pointing straight up, and she had no intention doing a hoof-stand in a public bathroom.

"What am I going to do with you?" she muttered to herself in the otherwise-empty bathroom. She sat and waited, closing her eyes and doing menial math problems in her head, waiting for it to go away as it had before. Confident that it would eventually, though it would take some time, Twilight waited patiently in the stall. After standing tall for some time, the cool air of the bathroom eventually made it begin to wilt, much to Twilight's relief.

The door to the bathroom opened. Twilight panicked but sat silent, motionless. Another mare trotted in and sat in another stall. Twilight could hear the familiar sound of a stream of urine splashing into the water of the toilet. The mare made it a brief affair, wiping, flushing, washing up and exiting. But she left something behind. Her aroma was heavy with her pheromones, bringing Twilight back to full mast. It was practically throbbing, so hard it almost hurt. "Dammit!" She remembered Shining's words.

Just jack off. That usually clears it up.

Twilight didn't want to even look at it, let alone touch it. But it was going to take a long time for it to go away. And every time another mare came it, she would have to start all over. It continued to stand tall before her, bobbing slightly with each heartbeat. She chewed her lip and brought her hooves up to it.

Her hooves barely touched it when it twitched at the contact, slapping against her belly. She took in in her hooves, with a better grip this time and just held it in place. She could feel its heat in her hooves. She could feel her pulse in it. It was racing.

Rub it up and down until you cum. Then you should be all set.

Without letting it go, she rubbed her hooves up and down along its length, per his instruction. She understood that the principle of masturbation was to simulate the pleasurable sensations of sexual intercourse. But after a lifetime of walking on them, it left her hooves with a coarse texture that was anything but pleasurable on the tender skin of her penis.

"How the hay does he do this?" she wondered. She realized what component of her simulation she was missing, lubrication. She reached into her bag, getting the bottle of conditioner. He had offered the one they had at home. He seemed to think that it was a suitable substitute. She opened the bottle and poured a bit on her hoof, and then applied it to her penis. "Cold!" she squeaked. She rubbed it, warming it as it spread. It certainly felt better. But it dried quickly over so large of a surface area. Well if a little is good... She poured a considerable larger amount in her hoof, and then the other, slathering the generous amount up and down her shaft. Twilight gasped and her legs trembled as she stroked. This was much better.

The door to the bathroom opened again. Another mare walked in. Twilight froze, hooves on cock. The other mare sat down in a stall, did her business, cleaned up and left. Twilight needed to hurry up and finish before she got caught. She stroked faster.

Shining stood under the warm shower of water, enjoying the feeling of it like he normally would. But he knew Twilight would be home soon and that he needed to hurry up. They had one of those removable shower heads on a line of hose to make it easier to wash up. His mane and most of his coat was still perfectly clean from last night's shower. It was his tail and hindquarters that needed the water's attention. He turned and, using his magic, brought the shower head to his tail, giving it a deep rinse, getting all of his... feminine wetness washed out. He lifted his tail and sprayed his undercarriage. It was a wide, diffuse spray, and he was trying to focus on a small, specific area. The shower head had a massage feature that he'd often use on sore muscles after a workout. He figured that since it had a more directed stream of water, that it would work well for this task. He adjusted the shower head and pointed it at his sticky marehood again.

Shining Armor instantly saw starbursts in his eyes. He dropped the shower head on the floor of the tub and his knees gave out from under him, sending him careening forward, and smacking his head on the tile wall. He struggled to pick himself up, gasping for air. It was the most intense sensation he'd ever felt! It was as though he'd jacked off, came, and then tried to jack off again immediately, overstimulated to the point of pain.

"What the fuck was that?" he gasped. He was able to recover fairly quickly. But for a moment, he was as incapacitated as though he'd gotten fifty thousand volts straight to the nads (if he still had them). He grabbed the shower head, bracing himself this time. He might have been caught unawares the first time, but this time he was ready. He hoped. Shining brought the stream of water to his tail, familiar territory. He lowered it down, along his dock. Same there. He pointed it at his butt. He didn't care to admit that he'd tried it before as a stallion. But sure enough it was as he expected it would be.

He took a deep breath and inched it lower, steeling himself for whatever might happen next. It sprayed the warm water at the top of his marehood, some of the warm water going inside his vagina. He giggled at the sensation. It was strange, but pleasant. And not at all like the debilitating shock that he'd gotten before. He brought it down to the other end of his slit and-

"GAAAAAAGHHHH!!!" Shining's back arched and he dropped the shower head again. He managed to catch himself this time, instead of falling. Shining's vision blurred a bit again, but was beginning to piece together the puzzle. He opened the curtain and grabbed the mirror from the counter, squatting over it. He looked down and spread himself again. This time though, instead of focusing on the 'part where the dick goes in', Shining took a closer look at the other end of the slit. There was a little nub of flesh there that had escaped his notice before. He pulled back at the lips a little more, exposing it better. He brought his hoof to it and-

"GHAAAAHAHAA!" Shining's leg kicked out from under him, sending him on his back in the slippery tub. The shower head arched water through the air, striking him in just the right spot. It wasn't the close range blast that he'd given himself before. It was the more familiar feeling of building pleasure toward release. Shining scooted himself into a more comfortable position and used a lower pressure of water. His legs trembled, but held him. He could feel it building in his tummy, a knot pulling tighter as he built himself up. He was getting closer, his legs shaking in time with the rhythmic pulses of the water jet. He held it there and then moved it away briefly before returning again, building up the feeling more and more until-

"NGGH! NGHHH! NGAAH!!" Sweet release. Shining fell forward onto his elbow, his rump instinctively pointing up in the air, rocking and bucking backwards at an absent stallion as his orgasm overtook him, spurting mare juices. It wasn't like cumming as a stallion, a building pressure that burst forth like an exploding firework, and ending just as quickly. He could feel his internal mare muscles flexing and clenching at an absent penis. Each time it was a wave of pleasure. Not and explosion, but a wave. A series of waves, big at first, and gradually getting smaller, washing over him, tingling all through his body like electricity, making his fur stand on end, or it would if it wasn't wet. Gradually he felt the rush cool down. Along with the water. Realizing that he'd been in the shower so long as to use all of the hot water, he hastily finished rinsing and toweled himself dry. Taking care not to spend too much time drying there and getting himself worked up again. He headed downstairs to be ready to greet Twilight when she got home with the groceries.

Twilight could feel herself getting close to... something, as she stroked her shaft. It was like walking up to the edge of a cliff, daring to jump over the edge. But the last couple of times that she'd gotten to the edge, it felt like too much and she had to back off. Clear liquid would appear from the tip, but it wasn't the big release that she was after, the one she knew would come. This time she was ready. She was going to keep going, she told herself, even if it hurt. She needed to finish. She gave herself some more conditioner and stroked with both hooves. She stroked faster. She felt herself getting close. She was going to do it this time.

The door to the bathroom opened. Twilight froze with her hooves in place, her orgasm denied again. She felt her balls beginning to ache as the mare beside her relieved herself. Again, the air smelled of mare pheromones from her urine. Twilight could feel her cock throbbing as her nose was filled with the scent. She grit her teeth, waiting for endless second for the mare to get out so she could finish. The instant the door closed behind her leaving the bathroom, Twilight's hooves were a blur on her shaft. She just kept thinking about that mare in line, and then about Trixie. She was so mad at her, she was going to fuck her when she got back! Right in her tight little- "Oooogh!" She sped toward that cliff of pleasure, her every nerve feeling electrocuted. It was almost too much. Almost.

"GRR GRR GRRAAH!" Twilight's eyes clenched as tight as her teeth trying to stifle her moan. She smashed through that last barrier, fighting through the over-stimulation. She was going to cum even if it killed her! Then she felt it, like a tree branch inside her snapping, the feeling of weightlessness in the plunge over the cliff, past the point of no return. She felt her balls pull up and tighten, the head of her dick flared even wider than her eyes were as she looked down at it. Her racing thoughts of fucking, of mares and stallions, sex and pleasure, right and wrong, all of is stopped. For the tiniest fraction of a second, her mind was a black hole of nothingness. Utter peace. And then- it happened. She came.

The first rope, the most voluminous, rocketed out of her like a bullet. Unfortunately, she was pointing it directly at herself. It shot right into her gaping mouth. The next, nearly as much, got her across the nose and cheek as she tried to look away. The third glob soaked her horn and mane. The rest hit her chin and dribbled down her chest.

Twilight couldn't even move. Her legs were shaking even worse than her trembling hooves were as her cock continued to twitch in orgasm, even after it had finished releasing its load. She felt completely spent, as though her very life force had exited her body along with the semen. The cliche of a stallion wanting to roll over and go right to sleep after sex gained some credence in her mind. As her erection finally began to shrink, Twilight looked at herself, and at the closed space around her. She laughed. She had to. Because at this point if she didn't laugh, she was going to cry.

Cum had gotten everywhere!

It wasn't so much that there was a comically absurd amount of it. But rather, droplets of it had spattered on the walls and door of the stall. Small puddles had accumulated on the tile floor. Twilight tried in vain to wipe what she could from her horn and face. The toilet paper was laughably inadequate for the task. Her mane and fur were sticky and matted. Her dress was irreparably stained. And it was all she could taste and smell. Less than an hour ago, she didn't even want to look at it. Now it flooded her every sense. Not wanting to add to the mess that she was already wearing, she swallowed the load in her mouth without thinking. Twilight wanted to be repulsed, she really did. It was a unique combination of savory, salty, and a little bitter, a bit on the watery side.

It didn't taste bad, she decided, licking her lips to confirm. She needed to focus on the positives here. Her erection finally retreated into its sheath. And its cum didn't taste bad. That was two positive things. Twilight stood up and made herself look a decent as she could manage, despite being marred head to hoof with quickly-drying semen. She splashed some water from the sink on her face causing the cum to turn into some new, unknown substance, curdled and impossible to get out of her fur without serious scrubbing and a lot of soap.

Twilight looked behind her at the mess, still in the stall. She pitied the poor soul that would have to deal with that tonight. She fixed her cum-stained dress just enough to cover her male half, strapped on her bag and wiped her mane one last time. She looked back in the mirror and mentally abandoned her last scrap of dignity, took a deep breath, and braced herself for what she had to do next.

Twilight opened the door and walked back out into the store, avoiding eye contact with anypony there as she made a bee line for the exit. She positively reeked of sex. It was impossible for anypony present to mistake it for anything else. She exited the store and ran home as fast as her hooves could carry her.
