A Horse Divided

Twilight had taken longer than he had expected to get home. Shining Armor was waiting instead in his bedroom. He had been digging though boxes of stuff in his closet storage and managed to find some of his old comic books. Having finally gotten himself off as a mare in the shower, they'd been serving him well enough now to keep his mind distracted from thinking about touching himself any more. He looked up from his reading only when he'd heard the front door slam. Before he could even get out into the hallway, the door to the bathroom slammed closed.

"Twilie?" he called out.

"Go away!" she said from inside. Twilight stripped off her clothes and stuffed them into the laundry bin. Her penis was hanging out just a little. It wasn't a hard erection like before. But it was coupled with a familiar sensation that she did understand. She needed to pee. She reflexively sat on the toilet, trying to point it downwards, under her. When it became clear that method wasn't going to work, she got up and changed her approach. Colts do it standing up. She never wanted to look at it again, let alone touch it. But she reared up and put a hoof on the back of the toilet. Holding her length with her free hoof, and aiming it into the bowl, she let it fly. "Gah!"

Having cum so recently, her stream did not go in a single, predictable arc. It was a split stream going in multiple directions, wetting the seat that she'd neglected to lift. He knees bent immediately, as she squatted over the toilet, holding her penis lower until it was practically in the toilet. After a moment, her urine cleared her system of semen and became a single stream. She stood back up and maneuvered it playfully in a small circle around the toilet until she finished. She could see while stallions enjoyed writing in the snow. She turned the water to the shower on and stepped inside.

"Why is there no hot water?!" She yelled out. Shining had since silently walked away from the door, heading down to the kitchen. The shower didn't stop running. For whatever reason, she was forcing herself to bathe with lukewarm water, at best. In the kitchen, the shopping saddle-bags were practically tossed on the floor. Shining picked them up, setting them on the table. They had spots of... something on the outside of them. It was white and sticky and smelled like... Shining froze in instant recognition, and stepped back from the table, looking up the stairs at the sound of the water running.

Twilight poured generous amounts of soap into the scrub brush, working the mess out of her mane and fur. The strange combination of bliss and shame that she'd felt after her male orgasm left her feeling queasy. Either that or it was from sprinting several city blocks with two full saddle bags and not real athleticism.

The soap helped immensely, separating the globs of the unspeakable from her lavender fur. But it was starting to accumulate in the grill of the drain. She finished her very-not-warm shower as quickly as she could and turned off the water. It was then that she realized that she'd been crying. She felt awful, running through the neighborhood covered in semen. As she toweled off she prayed that nopony she knew had seen her running. She'd do a load laundry later this weekend, she decided. She didn't need her mom finding that.

"Twilie?" she heard from outside the bathroom door again.

"I said, go away!" she shouted.

"What happened? Are you okay?" he asked out of genuine concern. "I thought I heard you cr-"

"I'm fine!" Twilight lied, toweling her mane while she wiped her eyes dry with the towel.

Outside, Shining waited, wanting to say something, anything that might help. But he remembered when he was a colt discovering himself. The best thing right now was to just pretend nothing happened. For both their sake. Twilight waited until she heard his hooves heading back downstairs before she unlocked the door. She wrapped the towel around her waist and quickly walked into the hallway.

Downstairs, Shining heard her hoof steps making a direct path to her room before she closed the door. He didn't have to have super hearing to know that she'd locked it. Shining had never been in a relationship, but he knew from watching his parents that when a mare said that they were "fine" it usually meant that they were anything but. But he knew better than to press the issue, and decided to just give her her space for now. He turned his attention back to the groceries on the table.

He carefully opened the bags and emptied them without letting the stains touch anything. He folded the soiled bags in his magic and trotted upstairs, cramming them into the bottom of the hamper next to... Shining pulled out the dress that Twilight had been wearing. As he looked at it, he felt like a forensic investigator analyzing the scene of a crime. A gruff detective voice in his inner monologue described the carnage on the dress.

"... appears to be the victim of a gun blast, judging by the spray pattern, it looks to be self-inflicted."

He stuffed it back into the hamper along with the bag and walked back down to the kitchen. Whatever had happened, it had to have been embarrassing for the poor filly. Part of him wished that her curiosity could have at least been enjoying this situation as mush as he'd been with his. She was so smart, smarter than him, but so naive when it came to certain things.

Shining sorted the groceries. A bottle of juice, bread, peanut butter & jelly. At the very least, they could live on PB&J's. For produce, he noticed that the apples he'd asked for were notably missing. There were carrots, bananas, cucumbers, squash, zucchini... Whether she'd done it subconsciously or not, Shining was seeing a pattern in the shape of the produce. His tail drifted skywards.

He levitated one of the carrots out of the bunch. The longest one of course. It was longer than anything else on the table. Nearly as long as he remembered himself being as a stallion. For a long minute he just held it there and looked at it, mentally trying to talk himself out of it. "This is a bad idea," he said to himself quietly. "Let the record show that I at least acknowledged it." He just looked at it for another minute, wrestling with the idea. "...fuck it." He licked the carrot until he was certain that it was well-enough lubricated and brought it to his marehood, pushing the tip inside without ceremony.

Like the brush handle, there was little resistance to the narrow intruder. However, Shining found that the irregular texture of the surface of the carrot was far more stimulating than the smooth, wooden brush handle. He pushed it further inside, curious to see how much of it he could take. He fed more of it inside with his magic. He could feel it moving deeper inside him, rubbing along the insides of his sensitive vaginal walls. Just after he felt the other, thicker end vanish inside, he felt a weird feeling in his belly when the leading end bumped into his cervix. It was a strange sensation, a mix of pleasure and pain, like if he had played with his balls a bit too roughly.

Backing off a bit, he moved the carrot in and out like he had before with the brush. He always thought that having a long dick was important because the deeper you went, the better it was for her, but it didn't feel like it now. He tried going faster and harder. It was different, but not much better. He could tell that he would end up chaffing before he was able to get himself off at this rate. He recalled the importance of thickness as well, regarding being a pleasurable stallionhood. It was a quality the narrow carrot lacked.

He removed the carrot and put it back on the table. He would wash it as soon as he was done. He picked up the squash. It wasn't very long, but it was easily the thickest item on the table. In fact, it was thicker than he was as a stallion by far. Because if a little thickness is good, more must be better, he reasoned. He licked the rounded end and pushed it against his vagina. He was met with significant resistance. He checked to make sure he wasn't aiming at the wrong hole and tried again, pushing harder. He could feel it stretching, trying to make space, but then he felt a sharp burning pain. "Ow owow ow!" He put it back on the table and crossed his hind legs. Clearly there was a limit to how far he could stretch, and he had found it.

As quickly as the pain had come on, it faded, leaving him in the lurch once more, aching for relief. The zucchini on the table was much more analogous to his own member in both thickness and slight curvature. "And the third bowl of pourage was just right," Shining said, reciting a line from a fairly tale. He licked the zucchini as he had the others and brought it to his quite-wet pussy. It didn't pop inside immediately like the carrot did. But neither did it try to break him as the squash had. He felt his lips stretch comfortable around it as he slowly pushed it inside. The round, bulbous end slipped slowly inside, filling him in the way that he hadn't even known he had needed until this moment.

Just as with the head of a stallion's penis, once the thickest part was inside, the difficult part was over. Shining felt the fullness moving through his abdomen. It was a void, whose dimensions he was only tenuously aware of from experimenting with the brush handle and carrot. But now, filled with the length and girth of the zucchini, he began to truly understand why a mare would want to go through the pain of a second foal. This feeling of fullness, that void, the hole inside him, filled, felt so... perfect.

He moved the zucchini further inside until it was completely in, then pulled it back out in a smooth motion, exacerbating his need to fill the emptiness it left. While it lacked the irregular texture of the carrot, the thickness was enough stimulation on its own. He pushed it back inside with his magic, repeating the motions. Straight in and out as before. It felt better, being thicker, but there was still something lacking.

He couldn't help but notice his elbows involuntarily buckling, causing his ass to point up into the air as he fucked himself. Rather than switching to another vegetable, Shining tried using the same, but at a slightly different angle, as his hips seemed to be prompting of the faux phallus. His sister would have been proud of his application of the scientific method, if perhaps in another context. He imagined a stallion, towering over a mare in such a position, below him. The natural angle would be for him to be rutting downward to her hips. He adjusted the angle of the zucchini, and pushed it back inside at an oblique angle.

He felt different with each thrust he gave himself now, as it pushed against the front wall of his vagina. He looked under himself, watching the bulge it made, poking out of his belly. He put his hoof to the lavender section of fur that was once his sister's, and saw and felt the zucchini moving in and out, inside of him, beneath his hoof. He could feel a pressure building. But it wasn't like when he was playing with his clitoris. It was more diffuse. It felt as though it was a growing need to pee, even though he had already emptied his bladder very recently. It wasn't an urgent sensation. And he had masturbated while holding it before, as a stallion, so he was confident that even if it were the case, it wasn't an issue worth stopping for.

He continued to stimulate his unbeknownst G-spot, thrusting the vegetable in and out of him. He could feel the pressure growing with each penetration against his vaginal front wall. It was a blend of feelings, less like needing to pee, and more like a familiar sensation as a stallion. A growing need to cum. Not just to orgasm as a mare, but to physically release cum. He was teetering on the brink of climax, each withdrawal, pushing him to the edge, and each thrust back inside holding him back, but raising the cliff higher until he could take no more.

Cum or not, he needed to pull it out of his aching loins, if only for a break. But without the pressure of the zucchini pressing on his g-spot, he was finally able to release his pent-up juice. And cum he did. His body shivered and his legs convulsed as his pussy spurted droplets in a high arc, peppering the rest of the produce.

Shining drooled on the floor in the afterglow of his orgasm. But it wasn't the exhausting experience that prompted him to want to sleep afterwards like as a stallion. Quite in fact, he still felt quite aroused, raring to go for another round. He put the zucchini on the table and decided to take it easy with a bit of a cool-down session. He opted for a smaller of the carrots, slipping it inside his vagina until it vanished within. His legs were a bit shaky, so he took a seat at the table. He sat and closed his eyes as his magic moved the carrot inside him, slowly up and down for several minutes. Not really building to a climax, but rather, just holding him at a lower plateau of pleasure. It was really quite relaxing.

Shining heard Twilight's bedroom door open and she trotted down the stairs before he even had time to react. He panicked, releasing his hold on the carrot with his magic, lest she suspect his glowing horn. Shining was trapped on the chair as she walked into the kitchen. If he stood now, the carrot, still subject to gravity, would fall from his wet nethers and the jig would be up.

"F-feeling better?" he asked with genuine concern, trying to keep the blush from his face.

"Yeah. I just needed to lay down for a bit," Twilight said, walking over to the table. He was almost used to his new lower half. But it was still weird for him to see his former half attached to his sister like that. He could only imagine that she felt the same way about him, even if she hadn't acquired his level of comfort with her new half. She pulled out the other chair and sat. "Oof," she grunted and adjusted herself.

"You okay?" he asked.

"Yeah, I keep sitting on your, er my balls." She grimaced and shifted her weight. "I never noticed how big they were." Shining felt a weird mixture of embarrassment and pride.

"Well, I guess I wouldn't have expected you to. Before," he said. He imagined her stealing glimpses of his privates while they were still attached to him.

"I'm sure I'll feel better once I've had something to eat," she said, picking up the longest carrot on the table.

"Twi!" He tried to warn her, but it was too late. It was already in her mouth. The produce, while dry at this point, was surely coated with his feminine residue. She took two big bites, chewing on them. Shining sat stock-still, in abject shock, staring at her, as though expecting her to spontaneously combust.

"Yah?" she asked, with her mouth full of carrot that had been bottomed out inside his vagina only minutes earlier. Shining stared, watching her swallow the mouthful, the bulge moving down her throat and into her gullet. He felt a tingle in his nethers in the illicit knowledge at the sight. She took another bite, again, chewing slowly.

"I- I was going to say," he stuttered, "t-that maybe you should w-wash the produce before you eat it. You have no idea-" she swallowed the next mouthful, "...where it's been." Twilight shrugged and took another bite.

"Eh. Whatever." She held out her hoof and offered him the rest of the carrot. "You want some?" He looked at it like it was an active grenade.

"N-No thank you. I'm not hungry," he lied. Twilight shrugged and ate the rest, taking inventory of the vegetables. She counted four on the table, plus the one she ate, which made five.

"I thought I bought six carrots." She didn't look when she tossed her bags on the table on her way in. Perhaps it rolled away. She glanced around on the floor, under the table, unable to locate it. She reached out with her magic, trying to locate it. She detected it nearby, but she couldn't pinpoint its location. Shining watched as her horn glowed, grasping it with her magic, she tried to pull it to herself. He felt the carrot shifting inside of him, moving without his control. He stifled a grunt as it pressed forward, bulging his abdomen.

"Twi!" he barked. She paused her search. "It's inside me!" She looked up at him with a weird expression. He quickly amended his wording. "Inside- my stomach. Because I ate it! That's... why I'm not hungry," he lied. It was good enough for her.

"Oh." She released her grip on it, causing it to shift back again inside him. "That explains it." Shining finally exhaled, having stifled his moan. Twilight stood up and retrieved a large bowl from the kitchen cabinet, a knife and a cutting board. She started to chop up the rest of the vegetables and put them in the bowl for a salad. She stopped after the first couple, checking the shelf for a book. "Shoot, do you know where mom keeps her cook book?"

"Um, probably on her book shelf upstairs," he suggested.

"Okay. I'm going to go get it. Can you finish here?" she asked.

"Uh, sure." He waited until Twilight got to the top of the stairs, leaping out of the chair, and quickly pulling the carrot from himself. With no time to spare rinsing it, it was the first thing on the chopping block, mixed with the other carrots as he destroyed the evidence. Twilight was already back downstairs with the book by the time he got to the other vegetables, finishing the salad. The fresh juices of the cut produce camouflaged the other... fresh juices. Twilight craned her neck over the bowl.

"Hmm, smells good," she said, practically salivating. Shining winced as she stole a few slices from the bowl to snack on. "Sorry. I guess I must be hungrier than I thought!" she said. Even if she didn't recognize the taste or smell, the effect on physiology was the same. Her penis began to extend from its sheath. She looked down, between her legs. "Dammit!" She sat in the chair, careful this time to not sit on her family jewels. "Shining! How in the world do you live with this thing?" she asked in exasperation as it grew to full mast in front of her before their very eyes. Shining got himself a glass of juice, if only to have something to occupy his hooves while he sat and sipped at it.

"I guess I just get by somehow," he answered, trying to stay neutral. Twilight was on the verge of tears.

"Shining, can I tell you something?" she asked hesitantly. He looked up from his drink.

"Of course, Twilie. You can talk to me about anything."

"Promise you won't get mad?"

"Twi-"

"I know, I know. That's unfair to ask. But I just, I just..." she struggled to find the words.

"Twi, it's okay," he said, reaching across the table and putting his hoof on hers. "I promise I won't get mad. Now what's bothering you?" Twilight glanced down at her erection poking above the table, and cocked an eyebrow at him. "I mean besides the obvious." She could see the genuine concern in his eyes. He really did care very much about her.

"Well, it's just that today, at the market, I got a- an an errr-"

"Erection," he filled in, sensing her discomfort.

"Yeah. I got an... erection." She shifted in her seat. "And it was going to show through the dress, so I ran into the little fillies room and I- I..." She put her hooves over her face, to ashamed to admit what happened. Shining already knew though. He'd seen the carnage in the laundry bin already. And there was no joy for him in dragging this out unnecessarily.

"You had to deal with it," he said, saving her the trouble. "You had to masturbate." She looked up at him from behind her hooves and nodded.

"I had to!" she cried, "I had to use my hooves and- and touch it, and- and-"

"Twilight-"

"I'm so sorry!"

"Shhh, shh, shh!" He shushed her, "No more of that." He slid his chair over closer and wiped her eyes tenderly. "No more crying. You have nothing to apologize for. I told you to try to do exactly that very thing this morning. I wasn't going to be upset then, and I'm not now. It's not your fault. You didn't ask for this. Neither of us did. We just need to do what we can until this all gets fixed."

"But it was awful," she said, even as she stopped crying.

"Really?" he asked curiously. "I mean, I'm sure it wasn't ideal doing that in a public restroom, but was it really so bad otherwise?"

"Yeah. When it, when it um- when I finished it- it got everywhere," she said, motioning all over to herself. Shining smiled weakly and ran his hoof through his mane.

"Yeah, it uh, it can do that," he admitted. "But aside from the location and the, er- mess..." he trailed off. She looked at him, unsure of what he was getting at. He glanced away and smirked a little, looking at her again "Other than that, how was it?"

"I told you! It was awful!" she said, a bit angry. "It was-" she searched for the word. He was just sitting there, listening intently, waiting for her to say something. "It was-"

terrible horrible disgusting shameful embarrassing

She looked over at him, across the table.

amazing incredible euphoric ecstasy

"It was the most amazing thing I've ever felt," she admitted.

"Oh yeah?" he asked.

"Oh yes."

"Well at least something good came out of the predicament."

"Yeah..." she looked down at herself.

"And you want to feel it again?" he said.

"I do..." she said trailing off.

"But?"

"I don't want to do it again, masturbate."

"Oh." Shining didn't read any further into it, expecting her to take a cold shower as she had before. He peeled one of the bananas, sating his actual hunger Twilight watched him eat the banana. She felt herself throb at the sight of him taking that big banana in his mouth.

"Shining?"

"Hmm?"

"Could you do it?" she asked.

"Hmm!?" Shining nearly choked.

"Could you do that for me?" she asked, pointing at the banana, and then herself. Shining regarded the fruit nervously.

"You're asking me to... suck... your dick!?" he asked incredulously.

"Well, technically it's your dick. But I guess it's all the same."

"That doesn't make the proposition any more enticing!" he retorted.

"Shining, please? I- I really don't like penises. I think they're icky. I-"

"Icky?"

"Yeah. So could you take care of this for me?"

"Twilight, no."

"Please?"

"No!"

"Please!?" She all but whined like a little filly begging for cookies. Pleading with those deep, purple eyes. Unlike Twilight, he had absolutely no attraction to his own gender. But penis or not, she was no stallion. She was his little sister, pleading for help. Sure, it was a little weird. Actually it was a lot weird. He clenched his eyes, regretting the word before he even said it.

"Okay."

"What?"

"I said 'okay'. I'll do it," he said. Twilight practically beamed, leaping from her chair. "Whoa, whoa, whoa! Slow down. I'll deal with it for you but I'm not going to suck it," he said. Twilight sat back down in her chair, disappointed for a moment until she saw him walk over to her and kneel down in front of her.

He looked up at her, and then at the task at hoof in front of him. He didn't like penises any more than she did. Except for his own of course. Arguably, this was his in front of him, awaiting his attention. But it just wasn't the same. It was not at all the same. He brought his hooves forward, taking a hold of it. Twilight gasped at the contact of another pony's hooves on her penis. Shining closed his eyes and tried to pretend that it was his penis, or rather, pretend that it was still attached to him. The texture of it felt familiar to his hooves. But the absence of any pleasurable sensations for him left him with a strange feeling of dissonance.

He moved his hooves a little before remembering a vital ingredient to the equation. He spat into his hooves and spread the lubrication on her shaft. Twilight's heart leaped.

"Shiny."

His hooves froze for a moment as he tried to wrangle ten kinds of weird. Jacking off a penis not attached to him, knowing that he was sexually pleasuring his sibling, and hearing her moan his name while he did it. He tried to shake the feeling off, resuming his motions with his hooves. The sooner she came, the sooner this would be over. He wondered what it was in his mind that made him even consider agreeing to doing this. Maybe part of it was his feeling of guilt for clearly enjoying his new parts far more than she had been. He looked up at her eyes, staring back at him, on his knees between her legs.

He brought a hoof to the top of her shaft, smearing some of the precum that appeared, helping to lubricate his hooves. She moaned as he touched her sensitive tip. She wore a smile you could see for a mile. He tried to think about what he would want a mare to do for him in this situation. He brought one of his hooves from her shaft and cupped her balls, gently rolling them in his hoof. He felt her shaft grow yet more turgid in his hoof.

He leaned over her tip, spitting some more saliva directly on it, causing her hips to jerk involuntarily, bumping him in the snout with her cock. Without thinking, he reflexively licked his lips. He mentally cursed himself.

"Tongue, why have you betrayed me?"

Shining winced, unable to get away from the taste permeating his mouth now. He didn't retch instantly, as he had always figured that he would. Which wasn't to say that it tasted good to him at all. It was like getting a mouthful of ocean water. Not horrible. But certainly not something he wanted to have again. And it didn't help that it was smeared on his nose, flooding his olfactory senses as well. But if Shining could get through the sensory assault of spending a day on a three-hundred-cow dairy farm, he could get through this.

Shining worked his hooves up and down her shaft faster. Alternating with playing with her balls, and occasionally working on the tip.

"Ooh, that feels so good!" Twilight moaned, "Keep going!" His hooves worked faster, bringing her closer to her climax. Shining felt her balls get tighter in her scrotum. "Nghh, it's getting a little dry!" Twilight yelped. Shining quickly leaned over her tip, opening his mouth to spit on it. Before he could even react, she grabbed his mane with her hooves, pulling his head downward onto her dick, forcing it into his mouth. "Oh Shiny!" she cried as her hips bucked upwards. "I just need to- fuuuuuuuuck!" Shining was able to get a quick breath of air before she shoved more of her dick into his mouth, hitting the back of his throat. His first instinct was to bite, stopped only by the realization that he'd be getting it back tomorrow with teeth marks. He tried to pull away, but she held him fast. He felt the tip flare wide and he braced himself for what was coming next.

"GAAAhhhHH!" Twilight cried out as she felt the rush of cum shooting up her length into her brother's mouth. Shining gagged and cum came out his nose as he coughed. In the high of her orgasm, she lost control of her hooves, releasing his mane. Shining pulled off immediately, avoiding the second volley of semen. Twilights cock sprung upwards, shooting its load over his shoulder as he fell to the floor. Twilight continued to cum, launching the next few ropes across his back and in his mane. It throbbed and twitched in orgasm even after its load was spent. After a few moments, it retreated back into its sheath.

Twilight sat with eyes glazed over, gasping in the chair as Shining got to his hooves and walked to the sink, sticking his head under the faucet, gargling and rinsing his mouth out. After a few minutes, he dried his face with the dish towel and shuffled over to his seat, taking a sip of his juice, wincing at the mixed taste remaining on his tongue. Another sip and it was almost tolerable to be conscious. That would have to do, for now.

Twilight's eyes slowly came back into focus. Her orgasm that morning, while spectacular, was nothing, nothing compared to that, just now. It was the most amazing, most incredible, most wonderful- Twilight looked at her brother, sitting across from her. He didn't look too happy.

"Um, sorry about that. Are- are you okay?" she asked.

"Yeah, I'm uh, I'm alright. I just wasn't ready for that," he said. Twilight surveyed the damage. Globs of cum covered the chopped vegetables in the bowl on the table, appearing to the untrained eye to be salad dressing. Shining followed her eyes to the bowl. "I'm not eating that." Twilight chuckled.

"You sure? It doesn't taste too bad," she said. Shining stuck out his tongue.

"Well I'm glad you like it," he said, finishing his juice and putting some plastic wrap over the bowl, putting it in the mostly empty fridge. "I don't know about you but I'm ready for bed."

"Yeah. Me too," Twilight said. Shining wiped down the table and Twilight cleaned up the rest of the mess on the floor. Afterwards, he headed upstairs, with her following him. She didn't mean to be staring at his behind, or rather, hers. But it was still so strange to see. And smell. He lacked the experience to keep control of his flagging tail to hide his modesty. She tried not to stare. She tried, anyway. Twilight stopped at her bedroom door in the upstairs hallway.

"Hey, Shining?"

"What's up?"

"I know that didn't go like you'd planned but I, uh, I just wanted to say thank you. That felt really amazing! I owe you, big time!" she said. Shining considered what sexual favor exactly it was she was offering. He pushed the thought from his mind.

"Yeah, well, you're welcome. Just uh, you know, don't do that again," he said.

"Well after tomorrow, I won't need to," she said.

"Yup. Tomorrow everything goes back to normal," he said.

"Yeah. Normal." The brother and sister both just stood there for a minute, looking at each others two-tone bodies, wondering how anything could be back to 'normal' after all this weekend. Each waited for the other to say something, each content to wait.

"So, uh, goodnight, Twilie."

"Goodnight, BBBFF," she said. He grinned and walked into his bedroom. Twilight walked into hers and crawled into bed, pulling the covers over herself.
