A commission for electricspark (https://www.furaffinity.net/user/electricspark)

Electric Spark and his twin sister, Sweet Voltage are looking to gain up enough money to move out and find their own place to set up their own repair shop. There are hurdles they must go over before they will have enough. With a large industrial dryer they must fix, and growing feelings they never explored, together they will find a way.Click here for Part 2Click here for Part 3


To many, today was just another day in the life, but to Electric Spark, it was a marvelous day of discovery for many, many reasons! He'd gotten into trouble with his parents more than once for going into the Ponyville city dump, but it was the very best place to find the best electronics and broken gadgets to tinker with. For the most part, it was the usual rabble. There was a sewing machine, a mini-fridge, and a broken doll that had its battery pack ripped out. He had fixed many small items in the past, but today was the real deal! Today he found, perhaps, the biggest dryer he had ever seen in his entire life. On the spot, he opened up the hatch and started looked at the motor closely.

Normally, when someone threw away a dryer, it was because of the heater, or the ignitor, because they were more expensive than the entire rest of the unit. However, if he was looking at the engine correctly, it looked as if the drive motor was the one that died off. Overall, the dryer looked like a dump, but with a little TLC, it could be brought back to its former glory. Spark smiled big as he looked at the unit as a whole. It was doable, but he was going to need some serious help.

The sixteen year old unicorn used his horn's magic to lift part of the load. He bent down and carefully positioned his arms around the very wide, yellow metal frame. With some fancy leg work, the orange furred pony lifted the dryer unit. He carefully repositioned his feet under him as he slowly carried it over to his small red wagon, which already had a broken flashlight, a lamp, and a digital watch. He placed the dryer down on top of the wagon's rim.

Thankfully, he was prepared for just such an occasion, tying it down with some very durable rope. It wasn't perfect, he could only wrap the rope around it once, but he was very careful, pulling it home. He dug his hoofs down into the dirt as he struggled the last half a mile, sweating something fierce as he finally got it into his parents' garage. After a good splash of water on his face, and a drink for rest, he decided to head to their room.

Sweet Voltage, sat at her vanity, huffing a little as she looked at an electric fan. It's not so much that it was broken, but it was just not powerful enough. She looked at the voltage output, and the input pads. She increased their capacity, and got a stronger battery. Voltage and Spark were identical twins, almost perfectly identical, even the red and blue manes were the same, though the front of her hair was red, while the front of his was blue. They would have been exactly identical, had she not grown a very large pair of breasts.

She was a late bloomer, though, and her breasts had just started growing only the year before. She found herself gazing into her mirror, her breasts out and looking them over with both a judging eye, and admiration. She was doing that now, though, of course just doing that got boring after a while. Now she just sat topless at her vanity and worked on little electronics, or even played solitaire.

Her eyes widened as there was a knock at her door. She attached the last two battery panels, then put in the battery quick to make the fan start. Voltage got her bathrobe off of her chair and put it on, she was about to tie the belt around her waist, but then said screw it and went to open the door.

"Hey Volt, you need to come see this." The grin on his face made Voltage raise an eyebrow.

"Oh, really? Well let me get my-- What?" She asked as she saw his face. His eyes were more downward, staring below her face. She looked down to see that her robe had not only opened, but the fan behind her was making it blow toward Spark. Her pink nipples were very stiff from the cold air, and he found out that she kept her red and blue pubic hair nicely trimmed. She gasped a little and pulled her robe closed. Both of their faces turned bright red as she tied her robe with the cloth belt around her waist.

"Uh-ummm just show me what you got." Voltage said, pushing her brother's shoulder to turn him around and lead the way.

"Alright, yeah." He scratched the back of his head as he walked. Like her, he just wanted to act like it didn't happen. He brought her to the garage, and as he opened the door, her eyes lit up.

"What?! Where did you get this?" She asked, looking at the gigantic dryer. "You know what? Nevermind where, how did you get it here?"

"I lifted it onto my wagon, it wasn't so much heavy as it was awkward." There was a pause as he looked at it. "And heavy."

Voltage used her horn magic to open the hatch to the dryer's engine and looked it over.

"And it's not the ignitor?" She asked as she got up and went to her toolbox, starting to pull out her ratchets and screwdrivers.

"No, it looks like the drive motor." He said as he got out some more tools. "Not to mention, it's old and the moving parts will need a bit of spiffing up before it's fully fixed." He said, looking at her as she bent down to start unscrewing the screws holding the motor in place.

Her ass was in perfect view, and she was not wearing any panties. He made some effort to look away and concentrate on getting the door off of the hatch, but he found himself looking down at her ever present closed outer labia.

"Agh, there's something else holding this stupid motor in place." She lit up her horn to illuminate the inside of the motor hatch.

They began working the industrial dryer, taking it apart piece by piece. They cleaned the ball bearings inside the cycle, and dusted out the vents. For hours they replaced tiny parts, screws, bolts, and wires that were stripped. The wiring needed a lot of work. Luckily they had some extras from former, failed projects.

Hours passed by. They talked about how many bits they would be able to sell this unit for after they spruced it up. They were saving money to maybe one day rent an apartment together. They wanted to move out of Ponyville and get a place of their very own. Still, that was a little ways away. They hadn't been able to save much.

"Alright, you torqued the bolt to seventy inch pounds?" Voltage asked as she pulled off her safety goggles and put them on her head.

"Yup." Spark put his torque wrench in its case and shut the motor hatch. "It should be good to go."

He took the power plug, and shoved it into the wall. After just a few more once-overs, he nodded to Voltage, who set the dryer onto sixty minute dry load. She looked down to see that she was still wearing her bath robe, which was now spotted with several grease stains. She'd neglected to change into her coveralls before they got started. The excitement of finally handling a full blown machine was just too amazing to keep waiting.

"Aaaaand.... Push!" As Spark gave the signal, Voltage slapped the button into the machine and the machine started to make noise. But it wasn't turning. Spark looked into the hatch, and it looked like everything should have been working, but something was obviously wrong.

They turned it off, and they took another look at the driver. They stripped it apart and looked at every piece and finally, they found the problem. It was the wiring, of course. They needed to undo the connector, label the wires, test their voltage and replace at least five of them, and connect them to new prongs.

They put the drive back together, both of them working on either side and dividing up the bolts and screws. While Voltage held it down, Spark got in the last bolt with a considerable amount of force, straining to get it tightened down as far as it would possibly go.

Finally, they got it back into the machine and got it back to its position, screwing it down once again. Voltage got back up from the ground and bent over backward, three audible pops coming from her back. She grunted and bent her neck from side to side.

"Alright, that should be it." Spark put his ratchet back on the table and wiped his head of sweat. "You ready?"

"Yeah, if this doesn't work, we can come back to it tomorrow. I don't even know what time it is." She said, trying to see out the cracks of the garage door, but not getting much in the ways of whether it was light or dark outside.

"Yeah, I figured that's what we'd do too." He said and plugged the machine back into the wall.

Voltage set the knob back to sixty minute dry, and Spark closed the hatch once again. This time he only went for hand signals. He held up his hand and looked at her, both of them crossed their fingers, and Spark gave a hand chopping motion.

She slapped the button once again, and lo and behold, it turned on and it started working. The machine heated up, it spun, the knob worked just right, and there didn't seem to be any straining from the engine.

Both of them checked over the entire machine, hopeful that they wouldn't find anything more wrong with it, and the more they looked, the bigger their smiles got. They looked at one another after all of the checks were done. And to Spark's surprise Voltage leaped at him and wrapped her arms around his neck.

"We did it! Dear Celestia! We did it!"

"I can't believe it actually works, and it's going at full heat too!" He said as he held his hand on it, it was still hot.

They held each other tight and did a few dance steps, laughing and holding hands as they swung each other around. That was when both of their hips began to shine very bright. Both of them stopped dead in their tracks, and gazed at one another in amazement.

"No way!" Voltage said, starting to shuffle her robe open and looking at her hip to find that she had, in fact, gotten her cutie mark. Spark did the same, only he pulled down the side of his pants down to above his knee to see that he had gotten his as well.

"Oh sweet mother! We got our cutie mark!" Spark said, and both of them smiled looking at one another. Little did they know that they were also looking at one another as their crotches were very much exposed. Voltage could very clearly see the base of Spark's very large, light brown cock. Spark saw that her mound was completely exposed as well, only adding to his length as he hardened. "Wait... are they both..." He started to ask as he took a closer look at hers.

They were both given three bluish purple lightning bolts. Two were lower on their hip, while the one in between them were offset higher on the hip. They were simple designs, and that was fine with both of them. Neither of them had ever heard of having the same cutie mark. No matter how similar they were, there was always something different between them. Though neither of them saw any difference of any kind, they didn't question it. They were simply happy to have them.

After a good minute of admiring their cutie marks, they embraced once again. The embrace lasted a long while, Voltage even buried her muzzle into his broad neck, letting out a small moan.

That was when the house entrance door opened and a very large silhouette stood in the threshold. The twins released one another from their grasp before the door fully opened.

"Voltage? Spark? What are you kids doing in the garage at this hour? It's past your bedtime! Get your baths and get in bed." He said as he walked back into the kitchen.

They looked at one another, still smiling. There were even some tears in Voltage's eyes, she could barely contain herself.

While they did what they were told, neither of them could sleep. Voltage laid awake in their bunk bed, her hands behind her head, counting the bumps in the sheet rock of the ceiling. When that got played out, she turned over on her side and sighed. The moved her cover over her hip to reveal her cutie mark again. She illuminated her horn to get a good look at it, and she gave another little smile. Of all the things she could have gotten her cutie mark for, it had to be for fixing an industrial sized dryer unit. She supposed the next step was to find someone to sell the dryer to. After they made a few bits, they could think about moving out when they could.

Voltage couldn't even think of sleep at that moment. The two of them had just gotten their cutie marks, but neither of them could celebrate such a wondrous event. She uncovered herself. She was just wearing a pair of red panties and a long shirt that partially covered her thigh. She shook her head and finally decided to check on Spark. She was about to reach for the ladder to the lower bunk, but then she heard his breathing. He was rubbing something, it sounded like. That was when she looked down toward his lower bunk, and her mouth went agape.

There was a good twenty seconds where Spark didn't notice her, and the first thing Voltage noticed was Spark's especially long cock, fully erect as he jerked it with his eyes closed. Her hands went to her muzzle as she studied its length, and even looked down at his very large balls as they bobbed back and forth in his scrotum. Her eyes widened, and she didn't know it, but she became especially wet all the sudden.

"Volt!" He whispered as he opened his eyes and saw her. "I... uuhh..." The two of them stayed as they were. Her eyes widened and her hands covering her mouth as she gazed at his hard, thick member.

"Can I..." Voltage started, not knowing if she should actually ask. "Can I... touch it?"

There was another long silence between them, and before Spark could even answer, she began down the bunk ladder, closer to him. She took one last tentative step to the side of his bed, and reached. With one touch, he twitched.

"Oh, wow..." She whispered as she began to move her hand up and down in a rubbing motion. "It's amazing."

His breathing became more vigorous than when he was jerking himself, and only after a few tugs, a little bit of precum began to swell up from the opening on the head of his pulsing member. Slowly, she began to lean her head toward it. Her mouth opened, and she slowly worked his dick into her mouth.

His face became piping hot, and his cheeks went absolutely red. He sighed, and looked at her as she gazed into his eyes. Her tongue began to move a little bit over his soft, tight skin. She ever so gently began to bob her head up and down on the brown skin. The salty taste of his precum, and the warmth in her mouth was so strange, but also so welcome. Her hands worked to massage his shaft, being gentle, but still firm enough to make his manhood stiffen for a moment with every jerk.

She was getting hot, her face was flushed, and she had to take off her shirt. Her soft, round breasts rolled out from under her shirt. This caused him to gasp softly, and she smiled as his cock twitched, and the tip of it swelled. Voltage looked down to see his hand reaching up to her right breast, the one closest to him, and she grabbed his hand, putting it onto her chest. She clenched his hand onto her, making him squeeze her teet, especially the nipple.

They began to caress their bodies, and she even pulled her panties down, kicking them into the laundry hamper on the other side of the room. As Spark admired her gold hued fur and her closed outer labia, both of them gasped as the hallway light turned on. Both of them scrambled, and Voltage made her way up the ladder to her top bunk.

Their door opened as their mother looked in on them. Both of them were covered up. Spark was lying on his side, away from the door, and Voltage was on her back. She even got the sleep breathing down pat. It was obvious they had done this many times before.

Their mother smiled, and closed the door as she exited.

The two of them lied in their beds, neither of them wanted to make the first move, but both of them wanted the other. Their trains of thought were too much to bare. They knew it was wrong to have such feelings for one another, but now that they'd gone this far, they wanted to go deeper. It was too late, though, and Voltage was the first to fall asleep, with Spark soon to follow.

Getting ready in the morning was difficult, for obvious reasons. They exchanged their normal greetings, as they always did, but their looks were different when they faced one another. Too much was on their minds. While Spark brushed his teeth, Sweet Voltage was preparing what to wear for the day, and while Voltage took a shower, Spark was getting dressed. School was out for the time being, and neither of them had much else to do. However, both of them revealed that they had gotten their cutie marks to their parents.

Of course, their parents were ecstatic! Their Dad took Electric Spark to work and showed him off to his co-workers. Sweet Voltage went with her mother to go shopping for a few accessories to match her new cutie mark.

All the while, they were happy that their parents were happy, but the twins could only think of what happened last night, and what it meant between the two of them. Spark was the first one home, and as soon as he got him, he got out the phone book, setting it on the kitchen table. With his horn's magic, he turned the pages and began looking up laundromats, industrial areas, and pawn shops in the business section.

Many phone calls were made, and there were many no-takers. Apparently purchasing official equipment from a sixteen year old colt just wasn't "copasetic" with some businesses. At about eleven phone calls in, Spark finally gave up. He sighed, and saw Voltage walk in with her mother, holding several shopping bags.

She looked at him, and widened her eyes a little, smiling, knowing exactly what he was doing. He frowned back at her and shook his head, causing her to frown as well. She rolled her eyes and shrugged with a little smile, and he nodded. The two of them didn't have a great deal of interaction for the rest of that afternoon, and night set in once again.

After such a high point, the low point of the day the low points just dropped Spark's enthusiasm as he stepped into the bathroom. After removing his clothes, though, he smiled a little bit as he looked in the mirror to see his cutie mark. He also looked at his partially erect penis, and the two words, "it's amazing" replayed in his head. Spark noticed that it stiffened at the thought, but shook his head. He needed to concentrate on selling that dryer, and getting the money so that they can be that much closer to moving out of the place.

He turned on the shower and opened the curtain, stepping in. He wet his mane, and drenched himself in the hot, soothing water. His red and black hair on his head took on a more purplish hue when it was wet, and his golden orange fur did much the same into a much richer tone. He used a brush to wash his hair with mane shampoo, and once again he thought about those two big, beautiful eyes gazing at him. His sister's stare as she put her mouth on his erection haunted him in the most seductive way. He didn't get the chance to orgasm last night, and it was coming back to bite him, hard.

Before he knew it, his dick was twice as long and thick, standing upward. He scoffed at it, wishing that his cock would listen to reason instead of just gaining so much girth on a whim. What if it stayed that erect when he put a towel on his waist? It wouldn't cover anything! He rolled his eyes, and tried his best to think of Buck Ball or something else that didn't involve fellatio, or two sleek hands around his shaft, stroking him ever so softly, a tongue licking his tip and tasting his cum.

Before he knew it, his sex organ was fully erect and enjoying the shower along with him. He growled a little bit, and decided that he would have to sneak across the hallway if it was going to be stubborn.

He reached for the nozzle to turn off the shower, but was startled as the curtain opened up halfway to reveal his sister standing right there. She was naked, and getting ready to shower as well, until she saw the shadow of his extremely hard boner through the curtain. Her eyes widened, and he swore he could see she was salivating like crazy. Voltage slapped his hand away from the nozzles, and jumped into the shower as well. His steely dick went between her legs, rubbing up against her cunny as she embraced him, and she met him in a kiss.

Her lips almost seemed to attack his, as did her tongue as it invaded his mouth. His eyes opened wide, but he embraced her as well. The two of them enjoyed a very deep, long kiss as her tongue rubbed against his, and their hands began to caress one another's bodies. She let out a soft moan as his hand cupped her left breast, and squeezed it. He made sure to get her soft, pink nipple between his middle and forefinger. After a lengthy period of time, she broke the kiss, and the half open bedroom eyes she gave him almost made him turn to jelly.

"I need you... right now." She whispered, and gave him another tender kiss. Voltage turned around in front of him, facing the shower head. Looking back at him, she bent over and moved her tail out of the way to give him an amazing view of her ass, and her closed, beautiful quim. He found himself caressing her ass cheeks with both hands, his eyes wide, and his legs kneeling down to get an even better look. It didn't take long before his muzzle went to her pussy lips, giving them one good lick. His long tongue penetrated her outer labia, she let out a sudden outburst cry of passion before covering her mouth with one of her hands.

Spark grinned at this, and began licking her sweet lips freely. Voltage could barely contain herself. Her teeth clenched shut along with her eyes, and she gasped as she felt his thumbs spread her lips apart to reveal the pink skin of her vagina. His tongue worked over her lips ever so gently, and his lips attached for a moment to suck her pussy whole. Her hands went to the wall in front of the shower to hold herself up.

"You bastard..." She whispered loud enough for him to hear him. "Please! Stop teasing me! I need you to fuck me!"

As she was saying this, he was already way ahead of her. He stood up on his hoofs, and very slowly, she could feel the tip of his horse cock putting pressure on her opening. Her eyes went haywire, and her hands slapped against the wall harder than she would have liked. She let out a small mewl of surprise as his girth stretched her pussy to the point of extreme sensations! There was a some pain, but she was so wet that he slid in with no real problems. She couldn't describe such a feeling, even with a full English degree, and a hundred days to think about it. She felt so full, and complete with his long cock rubbing against all of the walls of her tight, virgin tube.

He had broken her hymen, but she did not even notice. As he began to push in and out of her in long, firm strokes, she found herself unable to think. She could only feel. Voltage began to moan, and beg for more without even noticing she was doing it. His hands held onto her hips, where her cutie marks were, and pull her against his thrusts.

The warmth inside of her caused his large manhood to tingle in a way that he could never imagine. She was so wet, and the sounds she made only beckoned him to continue, even push harder. The view of his cock entering her stretched lips, and her butt cheeks parting to reveal her asshole caused his pleasure to escalate at an alarming rate. He didn't know it, but he had already caused her to cum twice, heading toward a third one. So, he began to bang her, and she no longer cared how loud her cries of pleasure were. Her wet hair covered her eyes as the shower rained down upon them. His hands traveled to her round butt and grasped it as he felt the semen travel up the length of his erection.

She could feel the first burst of cum inside of her, it shot deep inside of her, covering her walls and her cervix. The peak that she felt right then made her mind go blank, and delirious with blissful euphoria. Even though she had already orgasmed four times, the fifth one that happened along with him blanked all of them out, as it was the one she truly noticed. All six gushes of sperm invaded her vaginal tube and she gave no resistance.

Spark put his arms around her as he saw she was sliding down the wall. He held her up, and her arms went back to rest on his head. She turned her head toward him and met him in yet another kiss, this one was just the icing on the cake of the afterglow. Their senses were heightened, and Voltage could still feel Spark inside of her so clearly. She never wanted him to let go.

As they calmed down, and came to their senses, they realized that they had both been very loud. In fact they could practically bet that their parents were right outside the door, arms crossed with looks of extreme judgement. They dried off as they got out of the shower, and got on their bathrobes. Hers was brand new, as her last one now had grease and filth worked into its fabric.

Spark opened the door, and looked around. There was no pony in sight. Their parents were not home at all, it seemed.

"Did they say anything about leaving?" He asked, and she checked the refrigerator, seeing no note at all.

"No, they were both home when I got in the shower." That was when both of them turned as the door opened. Their parents came home, and apparently were across the street for half an hour, bragging about their kids fixing a giant dryer and getting their cutie marks at the same time.

Both the twins sighed in relief, especially when neither of their parents questioned why both of them were in bathrobes at the same time. They did not question their good fortune, they just took it as a sign of mercy, and went back into their room.

Over time, they began exploring their bodies more and more, discovering new ways to please one another, and learning how to bring one another to larger, more satisfying orgasms. Spark figured he had bent her over every surface in the house, and plowed her pussy to orgasm after orgasm.

Both of them even waited for their father to get off work, and fucked in the living room, trying their best to cum before he made it to the front of the house. It became one of the best games they ever played. There came a point where neither of them could sleep until Voltage mounted Spark in a reverse cowgirl position.

But then there was the matter of collecting money. There wasn't much in the ways of odd jobs in Ponyville, and they had only been able put together about a hundred bits, and they would need at least two hundred if this was going to work.

"So, Silken Suits says he won't take the dryer unless it can do dry cleaning, and honestly I don't have any idea if it has any kind of capability to do that or not." Spark said as he sat on the edge of the bed. She shook her head, fairly certain that it didn't. "Well, then our best bet is to try for the maintenance shop on the east side of town. If that doesn't work then we'll have to start on Cloudsdale, and I don't even know if it is even compatible on clouds. For all I know, it could fall through. Do you have any idea if it can fit on clouds?"

She shook her head, and slid his hard cock out of her mouth. "Our best bet is either sticking it here, or start calling people in Manehattan." She put his cock back in her mouth, and began to suck on the tip, letting it slide in and out of her mouth with her suction alone. He tried his best to keep his wits about him as she did.

"Kids?" They heard their father down the hall. Voltage got up quick, put her shirt back on and Spark pulled his bed cover over his lap, and his notepad. He got his pen and made it look like he was doing calculations while his sister wiped her mouth. Their dad opened the door and looked in, both of them were looking down at the notepad as their eyes went up to their father.

"Hey Dad, what's up?" Voltage said with the most proper smile she could muster.

"Ummm, there's a guy named Silken Suits on the horn, says he wanted to talk to you." He said as he turned and started walking back down the hallway.

Both of them looked at one another, and Voltage hopped out of the bed, and ran out the door while Spark got on his pants.

The girl pony raced to the livingroom where the phone was off the hook, and she picked it up.

"Hello?" Voltage held it up to her ear.

"Yes, hi, this is Silken Suits, and I was calling for Electric Spark." He said, his voice made it sound like he was surprised at the female voice.

"Oh, I'm Sweet Voltage, his partner in crime. Was this about the industrial sized dryer?"

"Ah, yes, actually. I thought it over, and it seemed we have found use for such a unit. Would you be willing to deliver it?" Silken asked, and he didn't seem to have any idea that Voltage's heart was starting to beat out of her chest.

"Yes, we can deliver it to your dry cleaner, no problem! And our asking price?" She smiled huge at Spark, who returned her smile, nodding in anticipation. She gave him another vigorous nod, and Spark began punching the air.

"Four hundred bits seems reasonable, if the unit is as large as you say it is. We will have full payment upon delivery." Silken said, "Thank you, we await your arrival. Tah-tah."

They both hung up the phone.

"We did it!" Voltage jumped onto Spark and the two shared a tight embrace. They jumped for joy! Finally, it seemed they had enough to get their own place, and open up their own shop!

Though the labor of pulling the dryer to the laundromat was hard, it was made easier with the two of them. They seemed happy with the load that the dryer was able to launder, and were more than happy to pay them. With the rest of their savings, they were finally ready!

The two of them got to work immediately, now that their schooling was all but finished in the public systems, they were able to find their own place. When their parents asked why they were getting one place between the two of them, they merely said that it was a good way to save money, and work together in their own repair shop.

After a good week of searching, they finally found the perfect one bedroom. The two of them opened the door to their new place, and it honestly didn't matter what it looked like. It was a little cramped, with a full kitchen and a livingroom all in one space, and one bathroom with a tiny shower. The bedroom couldn't hold a king size bed to save its life, and the front window didn't sit right, but none of that mattered at all.

The two of them dropped their bags in the middle of the empty livingroom, and both of them embraced in a kiss. They couldn't get their clothes off fast enough. As soon as Spark saw those beautiful, pink nipples on her tits, he attacked them. He latched onto her breast and began to suck, much to her delight. She blushed a little, and put her hand on his head.

"Mmmmm, shouldn't we start working on setting up shop?" She said, gasping as he rubbed his teeth over her nipple as it slid out of his mouth.

"Yup." He said this, but then pushed her back onto the couch, lifting her legs up and started kissing her nether lips. She moaned, and held his head as his lips rubbed against her moistening pussy.

"Ah! You said we should w-wait until tonight! OH!" She bit her bottom lip and let it go slack as he tongue hung out of her mouth.

"Do you want me to stop?" He paused only to ask that question, and lunged his tongue into her waiting cunt once more. The squeak she emitted told him that she certainly didn't want him to quit licking her sensitive, pink skin.

"Oh, dear sweet Celestia! I'm so happy we don't need to be so damn quiet anymore! Ah! Yes! Right there!" She began to twitch as his tongue ground against her clitoris. "Oh! Stop! No! Don't---" He stopped immediately, and she let out a gasp of relief, giving him an especially furrow browed look. "You ass, I was so close! Nnn!" She clenched her crotch with her hand and felt the juices that dripped out of it.

He wiped his mouth and grinned at her, only to be pushed on his back, with her pussy going straight to his face, and her going down to get a good muzzle on his hard, precumming cock. She got half of his shaft in her mouth and gorged on his cock. Her lips slobbered all over him, and Voltage jerked him hard with her clenched hands.

Before long, the two of them were licking and grinding against one another. His muzzle sucked her whole pussy as his fingers spread her ass cheeks. His tongue fucked her sweet hole, causing her to moan against his dick as she sucked all the way down and up the side of his very stiff shaft.

The race was on at that point, and neither of them were willing to give up without a fight. Had he not held it in, Spark would have cum directly into her face, but he could not believe the resistance she was putting up against his tongue. The two pony twins suddenly began to grin, after a while of fucking, the siblings had devised very interesting tricks for just such an occasion.

With the illumination of his horn, Spark began to use his magic to tease his sister's asshole, which was in plain view. Her mouth tightened over his massive penis, and she furrowed her brow in anger, but then decided to pull out all of the stops before it was too late. Her horn lit up as well, and brightened an aura around Spark's balls, giving them little twinkles of sensation that made his dick twitch in her mouth.

It did not take long at all. The two of them came, and came very hard. Voltage had trouble drinking so much semen as it jetted out of the tip of his member, but she kept up with very little spurting from the sides of her mouth. Spark did not fare as well, however. Her vaginal juices raced into his face, and his tongue just did not cut it. After a small rest, the young colt still had a truly hard dick, and that fact was not lost on Sweet Voltage.

"Hmmmm, well we've been practicing quite a bit on the other hole, if you wanted to do that again." She winked at him, and his eyes widened.

"But last time you couldn't sit down for the rest of the day." Spark looked at her with a raised eyebrow. Then he looked over at his bag, he was fairly certain he put the lube in the side pocket of it. If he put a little more lube on, it could probably work. Then he looked back over at her to see she was already on her knees, with her ass sticking straight up in the air. Her hands spread out her asscheeks to give him a perfect view of her alternate hole.

Spark shrugged, and rolled over to his bag, opening it up to get the lube. He stroked the gel on his cock to make it all slick and shiny.

"Now, if it hurts too much, you tell me, okay?" He said as he walked on his knees over behind her, and began rubbing his thumb over her asshole to get it lubed up as well.

"Just stick your cock up my ass, and we'll see what cums about." She stuck her tongue out at him as she turned her head. That was when she moaned as he stuck a finger into her anus. That slick, lubed feeling going into her ass was amazing. She laid her head on the ground and moved her ass with his hand as he rubbed the lube inside of her rectum. "Damnit, Spark! Just fuck my butt!"

Without another word, his finger left her ass, and a huge amount of pressure invaded her asshole. She gasped as it slid into her sphincter, causing her to let out a blissful cry. He started off slow, and soft, knowing that her ass needed time to adjust.

"Fuck! You're huge!" She said, knowing she was stating the obvious, but at that moment, she did not care. "Oh! Dear Celestia, fuck me harder!" She was riled up all the sudden, and Spark was more than happy to oblige.

Her ass clenched onto his shaft like a vise! The lube did its work, but she could still feel the edge of his head as it plunged into her lower depths, and rubbed her rectal walls so beautifully. The only real problem with the ass fucking was that Voltage got very loud, she loved it so much. At home they had to wait until their parents left, but here, it was fitting that they did it first.

The way his dick stretched her asshole was amazing to her. She began to sweat as his cock began to go deeper, and harder into her. Her eyes went cross for a moment. She could never describe the feeling, but she thrived in it. Every push into her ass caused her to moan louder. It wasn't long before his balls began to slap against her pussy as he fucked her mercilessly.

There was no helping it, she was going to cum soon, and she could do nothing but reach back and massage her pussy to build her pleasure higher. To her surprise, however, Spark began to breathe harder, and whisper in her ear about how wonderful her asshole was. Voltage decided to help him along.

"Oh, yes! That's so hot! Please! Pound me harder! Your dick feels so amazing! Fuck me!" She moaned ever so loudly with every pistoning fuck in her anal cavity. He came like a firehose into her ass, and triggered her own orgasm on top of it. She bit into the couch cushion and nearly screamed into it, closing her eyes tight with beads of sweat dripping down her face.

The sight of him pulling out of her ass, and cream dribbling out of it was a marvel to Spark. The twins collapsed on the floor next to one another, laying close.

The two of them held together tight, their muzzles connecting, as well as their horns. They closed their eyes and sighed. It'd been a long, hard road to get to where they were now, and now that they had a chance to make it on their own, they were determined to make it count. At length, Voltage giggled a little bit. After a moment's pause, she giggled once again.

"What?" He chuckled a little bit at her and opened his eyes to see her looking at him.

"Oh, with everything going on right now, it's just weird to be here. In front of his complimentary couch with you. After all of this, it's hard to believe we made it this far. Still, the way things are going..." She looked at the two of them, sweaty and partially dripping with cum. "We're never going to get any work done."

The two of them had a little chortle at that, but then went back to their warm embrace.
