Twilight Sparkle's body ached; the magic within the Crystal Heart seemed to drain from it in waves. The spell had been designed to create new protection, but that was not what had happened when she fell into Chrysalis' magic. Instead, it had been designed to create the most powerful of dark magic, and she should have expected that she would become a part of the darkness to go with it. But, she had been unable to resist the seductive magic, and now her mind was being corrupted. The spell had brought with it a terrible feeling to her head, and she felt that she was going mad. She could feel the dark magic draining from her, but she couldn't control it. She had a headache, but it didn't seem to be very bad at the moment. She was still unable to see, but she felt that she could feel herself moving and changing. It was as if her mind had been rewired, and she was now a part of something bigger. She was aware of her own thoughts and thoughts of others, and they flowed with her thoughts. She felt that she was being guided, and it made her feel like she was a part of the world around her, an extension of herself. She was being controlled by the dark energy. She felt that she would lose control if she tried to stop the process; there was no way to do that. She was already a part of it, and she could feel the energy coming from it. She also felt a great sense of power and powerlessness. The more she tried to stop the dark energy, the more she felt like she was losing control of herself, and the more her mind drifted to the thoughts of her past.
Twilight opened her eyes. She didn't know how long she'd been sleeping. Her vision blurring. She could hear Shining's snoring. The room was so dark it was nearly black, and she looked around in the darkness, her head hurt and she needed to get some air. She looked up and saw a door, with a light blinking on the inside. She reached in and touched the door, and it creaked. She quietly passed to his bed.
"Hey there, Twilight," Shining said drowsily. "What are you doing?"
Shining looked embarrassed.
The thought stopped him dead in his tracks and he looked up, surprised.
"I- I think I'm going to want to make you happy," Twilight said. A moment later, she lifted her head and looked at him. "I'm ready, Shining.", she hissed.
Shining's head fell back slightly as he felt Twilight's tongue lick over his entire head and nose. It was so fucking good.
"I… I'm almost in shock," he gasped out, his eyes dropping shut to the black void above them. Shining's eyes, still closed, finally opened as well as his mouth. He gasped, a mixture of surprise and excitement as a slight shiver ran through his body and his head.
"Twilight…" he mumbled out, his voice coming out as a high pitched hiss. "what… What are you doing, little sis?"
"I'm not just some little pony," she muttered, "I'm am Alicorn Goddess."
"Hah?" Shining said with a giggle. He didn't have the words, and it was not clear to him what she meant.
Twilight repeated, trying to gather up all the pieces that were crashing into her.
"I will be yours." Twilight took a long, loud breath, the sound coming from her lungs being completely overwhelmed. In that moment, she was filled with the desire to go all the way with Shining. She wanted it badly. She wanted to have every moment of their union with every fiber of her being. To be all the way with him. Shining's head was turned to her. The darkness around Twilight was like a veil, the queen's gaze only ever looking her way. The sound of her breathing, which had been coming out as a high pitched hiss that had been muffled by her tongue, was now coming out more like a roar. It became a low hiss that was close enough to fill the dark void Twilight had fallen into.
"You should come to me," she whispered into the darkness, "I can help you." There was a moment of silence as the two of them looked at each other. The two siblings stared at one another, their eyes shut tight. A moment later, dark emanations appeared as her mouth opened and a weave of purple light wrapped around the two of them. Her expression was a mixture of pleasure and relief, but she was also tired. Shining could see the exhaustion in her face, and she could hear the desire in Twilight's voice. The two of them were still stuck in the middle of a strange embrace, their bodies moving in sync, with the purple haze dissipating and the two of them falling deeper into a trance. Dark magic took on a life of its own, and it seemed to slowly grow in size, forming a glowing orb of energy around the two of them. When it reached the size of a small moon, it began to glow, before fading into darkness. The two of them sat there in complete calm, their minds.
In the meantime Twilight couldn't help but stare at Shining as she licked her lips, feeling her juices seep through her nether leaps. No matter how hard she tried she couldn't keep from moaning. She felt Shining's mouth over her, feeling the lips press against her own. She felt the back of Shining's neck pull her closer, the soft of his fur caressing her own. Slowly her mouth pressed down and Shining brought his entire body to her own, kissing Twilight deeply. The kiss was hard as can be.
"It's... it's amazing! I never thought I could taste this," Twilight stammered. Shining's eyes narrowed down on Twilight's face, but then it was gone, the grin on her face replaced by a look of total satisfaction. Shining pressed his hooves together, his horn glowing with a bright light as he pressed his mouth to Twilight's, kissing her and sucking on her tongue. When Shining pulled away, she looked at Twilight with a concern.
"I'm going to fuck you," she said, her voice husky with orgasm. "I'm going to make you cum so hard I can't even breathe."
Shining's eyes were wide with a combination of shock, fear, and utter confusion. Her mouth hung open. Twilight smiled down at her. She didn't say a word for a moment, only smiling at it all. She then leaned in, pulling Shining's face towards her, kissing him deeply again. It felt so good, so warm. Shining's body suddenly felt like it was on fire, his whole body shuddering as a surge of pleasure shot through it. Shining's blood began to boil, his tongue flicking out to taste her sister's lips. Twilights then pulled back and leaned in again. Shining's mouth hung open in shock, not knowing if he had just lost his mind, or if he was still going crazy over the incest. Twilights pulled back again, but this time it was on a different note, her mouth moving up and down on Shining's lips, bringing about a new sensation.
Shining's head bobbed up and down, his vision going blurry. He was still feeling the intense heat that had been building up in his body; he has pulled away and tossed against the bed. Her body jerked violently, and before he knew it, Twilight had been on top of him. Twilight pulled away and smiled, her lips still kissing Shining's own, and her eyes glazed over with lust. Once again, her horn came up to meet Shining's eyes, but this time Shining wasn't completely oblivious to the new sensation. His vision went fuzzy, and his body trembled with an orgasmic tingling.
Twilight's head bowed, her lips parting as she looked into Shining's eyes, his gaze a mixture of guilt and sorrow. His mind was still blank, though his eyes were glazed over and her jaw was slack. "You... You're... my... sister..." Shining's body trembled, his eyelids drooping shut.
"Oooooooh," she exclaimed, "it's so hot! Don't move!"
Twilight watched as Shining's eyes rolled back in his head as he moaned. The next thing she knew, she was laying on top of her brother, her nose pressed against his cock, her forehead pressed against his balls. Her tongue was pressed against the head, and she was practically screaming with pleasure.
"Oh my Celestia," Twilight gasped. "I just can't believe I'm doing this!"
Her tongue began to explore in earnest, lapping up and down the shaft. She found the head of Shining's cock and began to slide over it, swirling around it.
She slowly started to suck on the head of his cock, stroking it slowly as more of Shining's precum began to drip from his cockhead.
Twilight's lips were coated with the last drops of his pre-cum, and the only thing keeping her from swallowing it all in one massive gulp was the feeling of warmth and wetness in her mouth. She gulped it down, sucking it all in, and it tasted so good. Twilight began to swallow again, but she couldn't get enough of it. She wanted to swallow every single drop, and she was willing to do that if it meant her brother would finally cum. As she continued to swallow, she began to grind her muzzle back and forth, the tip of Shining's cock in her mouth, pressing in all the way. It felt amazing, and the more Twilight started to suck on it, the more intense it got.
The only thing she could think of doing right now was to make him cum. Once she was sure he was about to cum, she opened her eyes and looked at Shining with a smirk. "You have a lot of cum to go."
Shining looked down at his sister and Twilight immediately burst out laughing. Eventually, Shining moaned in pleasure, his cock pumping his semen into her mouth. She was so excited, and now that she'd gotten her fill with Shining, she couldn't wait to feel his hot cum on her tongue, and she wanted to feel it all over her muzzle. Shining's cock was still buried in her throat, and she wanted to go as deep as she could.
She felt the warm sticky cum that still coated her throat drip down her muzzle as her juices ran across her belly.
Twilight collapsed back onto the bed, breathing heavily from how much she enjoyed her experience.
As he cried out in pleasure and agony, Shining realized that he had just fucked his sister's throat. His cock throbbed, pulsing and spraying his seed as he continued to smear his sister, while Twilight was still writhing on her back, her wings still twitching uncontrollably and her body still quivering in ecstasy. Twilight was shuddering and breathing heavily, and she quickly rolled to her back. He looked down at her, still spamming with his own orgasm.
As she moved to clean up the mess, she felt her brother's cock press itself into her throat again, and once more. As she did so, she felt her brother's head snap back, and he started to moan.
Now that he was done, Twilight quickly started to work on her brother's balls, she quickly licked and licked at one of them, sucking it clean before moving on to the next. After a few minutes of this, she started to suck him gently, running her tongue around the underside of his shaft. Shining's cries grew louder, and she could feel his cum start to dribble around her tongue.
"I... I... I loved you..." She whispered, a bit louder than before. She looked at him adorably whorish glance. She took a deep breath and leaned forward, wrapping her mouth around Shining's, sucking at his neck, his cheeks moist with her own saliva. "I know how much you love me..." Then she swallowed hard, her breath coming in short, quick puffs.
He moved back, slowly, almost gingerly, and he was startled, but she was so pleased with herself, and she let him take her, even though she knew that it wasn't right, and he loved it.
"I wanted to make every moment of this night special and glorious."
It was so wrong, his body was writhing, trying desperately to break free from the feeling, but he couldn’t.
Shining began to realize that he was actually getting closer and closer to fucking his sister. The only way to keep up was to keep up with her. He began to slowly pull away from her, until she lost control and he ended up fucking her so hard that he lost his breath.
"What if we stop now?" Shining said, rubbing his balls.
"I'm going to have to go," he told her, reaching back to pull her over to bed. "I know you want to do this. But I need to be the one who pulls you back from this insane."
Twilight was in tears. "I want you!" Twilight said, her face blushed and her eyes gleaming with a flash. "I fucking want you! Please, Shining, please fuck me in your own bed! Please, just fuck me!"
Shining stared at her, and that was it. He couldn’t. He couldn’t. She knew he couldn’t, but she didn't take his eyes off her, didn’t stop looking away from him, didn’t stop his body from quivering and bucking. The way he was being thrust into her, and how his breathing got heavier and heavier, the way he knew he couldn’t stop. He didn't know how long it would take him, how long it would take her, but he knew he had to do it.
"Please, Shining," she whispered, her voice trembling, "please, please, please. Just say if you want me."
"Yes?" He said, feeling his cock twitch, his balls tighten and begin to swell. "Yes, I mean, yes, I want you."
And as Twilight shifted and her own hoof slid down her torso and between her legs and she sighs in pleasure, Shining knew it was just relief, just sensation. Just pleasure, a colt and a filly discovering what these things felt like for the first time, exploring, experimenting. Touching. Tasting. And so when he lost himself to her touch and he imagined her rolling over and beckoning him towards her, and then imagined mounting her and pushing her down against the bed covers and burying himself so deeply inside her, feeling her welcoming him in and clenching and tightening and milking, feeling her quiver and making her bite ever harder on her hoof, and how fucking hard that thought made him, it was okay. His hips bucked upwards, trying to thrust into a mare that wasn’t there. A mare with lavender fur and stars so beautifully adorning her rump, a mare that sat beside him and moaned and bucked her own hips just as much. He wondered if she was thinking the same things he was, forbidden and unwanted and not-counting thoughts of her own. Of pinning him beneath her and sinking down on top of him and letting those stifled moans fly free, she probably was, too, but he wasn’t. Maybe it was just the way she leaned in with her mouth, or the way the other mares were leaning down with their heads on him and their lips
He held her by her tail and pulled hard, forcing his tongue into her mouth.
And she didn’t stop him. She didn’t stop him.
The last bit of her mind was focused on the thought that they were already in bed together, her eyes were closed, her breath was shallow, and maybe she had wanted more than just to fuck him. She opened her eyes and slowly pulled away from him, letting her head fall back against the pillows, and she watched the dark shadows of her eyelashes flutter against the bedsheets, and she listened intently for the beat of her own heartbeat, for the sound of her own breathing.
"Oh Shining, you’ve been good. So good."
Shining groaned, and he knew his sister was right.
"Mmhmm," he moaned, feeling the soft tinge of the filly's magic as she began to rub herself against him. It was so delicious, he thought. So good, so fucking good. He would have done anything to give her that. The thought made him feel even more excited and aroused, the tingle of her magic making him feel so hot. So hot, and his hips bucked and he lost himself. The feeling of the soft fur against his face, and how fucking beautiful it was to watch her muzzle, her horn, her body, respond to his touch and his tongue. She was his, and he had to be perfect for her, he had to be everything that she wanted him to be. And that was a good feeling.
When he began to kiss her again, his mouth was a bit dry, so he licked at her neck, then around her jaw and up to her ears and then from there she felt a tug and his head was pulled back a little, back against the bed, but not too far, and she felt his tail wag around and the little light sparkle in his eyes. He gasped and his eyes fluttered open, and she felt his face against her back. She was looking into his eyes, but it was so wet, so hot, and he was breathing so hard. She opened her mouth to say something, but he whispered it, his voice so low and quiet, and her ears ringing.
As the feeling of her body against him grew and grew, and his cock grew too, and he found himself desperately wanting it more, it took everything he had to keep it from coming out. He came for the first time in a long time, but he didn't care anymore. He wasn't even there, just this sensation, this pleasure, all that he wanted. He wanted her, wanted that feeling so much more, he wanted her mouth on him; he wanted her thighs on his body and her tongue on his balls and that little shiver of her own in his belly. He wanted her to touch him; he wanted her teeth to grip his mane and his mane to brush against her mane and her hoofs to run up and down his body, to play with his mane and his tail. He wanted her so much that even on the edge of coming, he could feel it.
When he felt her tail wag his way back to his face, he leaned forward and kissed the back of her head and felt her hairbrush against his lips. She looked up at him and smiled sweetly. Shining was making slow, deliberate thrusts into her ass. He pulled out, and Twilight yanked him back in, forcing him back into her. He bucked forward and started pushing, her legs buckling. She could feel her own saliva coating the tip of Shining's cock, and she felt it slide in gently to fill her ass up. But when he tried to pull out, Twilight's magic pushed him back in again, pulling out his penis, too.
But Shining's cock got stuck in her ass and he kept pushing and pushing, feeling each thrust with a mixture of joy and pain. Her muscles tensed and her own orgasm began to build. She shook her head frantically, feeling the tip of Shining's cock dig into her ass, and then that was it. She could barely breathe as she felt his cock slide in and out of her ass, and she was aching for more. She wanted him to fuck her so badly, he was hard and he could feel the pleasure. Her ass pulsed as the pleasure filled her, and she couldn't help but moan. She felt the tip of Shining's cock slide out of her ass, and then he pulled out again, and again.
All the while, Twilight was pushing herself towards the edge of the bed, to the edge of the pillow, as she let out a gasp and pushed herself up, and then she was on her back, her back against the bed, her hips slamming against the mattress, her legs spread wide as she moaned, her eyes closed and her breath caught in her throat made it almost impossible for Shining to think of anything but her.
"I’ll do. I’ll do anything you want me to do." Twilight was breathing heavy now, her hooves clacking on the floor as she pulled herself up, her cheeks flushed and her breathing slow and heavy, but she kept her eyes closed, her eyes half-lidded, her mouth shut tight enough that it sounded like a sigh.
Shining was overcome with a sense of guilt but he had no time to think about that. He started pumping his cock in and out. Her ass tightening around him as he pushed in deeper. His cock was starting to get hard inside her, and he could feel the bulge in her ass grow as he forced his cock in. But it was his pleasure that filled her. She came, and he felt her come, and then he felt his own orgasm come as well, building to a peak. But he had to keep pumping, keeping his cock in her ass, until he exploded. Twilight felt her belly swell with the massive load of semen and she felt the weight of him on top of her. The entire time, the rest of Twilight's body was bouncing and twitching, her horn jangling as she climaxed furiously. Shining pounded his huge, pulsing cock against her sister’s belly. All the while, Shining continued to slam into her, his spittle shooting everywhere as his sperm dribbled out of her ass. Twilight gave a soft moan of pleasure as she saw the spurt of sperm leave her sister’s asshole, then gushed from her ass onto her cunt and she began pumping her ass, squirting more of her brother’s spunk into her. Eventually, her asshole was completely emptied, Twilight had sputtered out all his remaining sperm. The pain in her ass had quickly returned. With a final breath, Twilight slumped onto her stomach. Shining was now lying on top of her. She didn’t want to leave, but the brother’s body was too heavy.
Twilight was still panting, holding her breath, but her horn was still glowing as well. After a few moments, Twilight looked up and saw that her brother had a large, rumbling grin on his face, while the two of them lay in a pool of cum.
The massive cock of the stallion pulled her back and slid into her pussy, filling her so completely that she thought she was going to pass out.
He thrust into her, as hard as he could, his body clenching and his mind buzzing, but he didn’t feel her grinding against him. He felt her warm, wet fur against his belly, her soft maw open and waiting to receive him, but he didn't feel her breathing, her heartbeat, and her hips. He felt everything.
He collapsed on top of her, his huge cock pressed against his sister's womb. He let out a soft moan as his sister’s juices flowed down his dick, making him gasp for breath. Twilight was still breathing heavily as he pushed his cockhead into her cunt, and she cried out for her brother to pull away from her, but he didn’t. Without a doubt, he was still breathing heavily as he lay there on top of his sister’s body, writhing with pleasure.
Twilight's eyes rolled back in her head as she felt Shining's cock brush against her clit. Twilight had lost all control over her body’s movement, her whole body shambling to and fro as she continued to scream of pleasure. Her entire body went rigid as she began to writhe on the bed with her legs spread wide, the muscles of her body shaking as she thrashed. Her big brother’s tail swished through the air. And just as Twilight’s wings were about to snap. Twilight cried as her body began to spasm and spasm, her entire body bucking violently from the massive cock being thrust into her. Her horn began to glow suddenly, as a purple cloud of magic formed, and then exploded out of the tip of her horn. The pink and purple light enveloped Twilight, and after a few seconds, she let out a loud moan. The cloud of magic was quickly consumed by the massive cock inside of Twilight, as she screamed out in pleasure.
"T-THAT. IS. AMAZING." Twilight was panting and her breath was coming out in gasps, her eyes still shut, but she looked like she was going to collapse or fall off of the bed, she was shaking so hard her muzzle was almost in the way of her hooves, her hooves were so tangled around her, her legs were so weak. Shining couldn't feel it in his bones, couldn't feel the warmth of the mare's body, but he was sure she was enjoying this; she was enjoying the pleasure of a mare.
When Shining was a little further down, she screamed again, and again. The new sensation was incredible - she was in a world of her own. She was fucking herself on the tip of Twilight's cock, and the way she filled her with her shaft was... breathtaking. She could feel Twilight's balls tightening around it, she could feel it swelling and she could feel it contracting and relaxing. She could almost feel the pulsing in her belly, the way the balls and the walls of the vagina clamped down and felt the pleasure surge through her. She felt herself getting filled inside, her back arching with the force. She felt balls slapping against her, and she felt tip pressing against her clit and she felt herself pulsing and pumping.
She coughed and gagged, but she was too weak to fight back, so she just let it go. The orgasm left her in the position she was in.
Shining gasped with lust, his cock twitching inside his sister. He was so close. So close.
He was so close, and he was so fucking heavy. He needed to release, to cum, to fill her up again and again, to make her orgasm again, and again, and again. His body was so far gone that Twilight felt it would explode in her womb if he did not keep his eyes open.
"Oh my, fucking Celestia," Twilight said, her voice barely above a whisper through her lips. "Oh, Shining, I’m going to c-cum again, you’re going to c cum in me.”
"No".
"I don't know why you're resisting. This is so hot."
He couldn’t stop it. All the thoughts that were weighing him down were rushing through his head, making him want to cum. His mind was racing. What if he’d cum in her? And if he did, what if… What if…
"Mmmphhhhhhhhhh." Twilight moaned and her eyes rolled back in her head as she took in the sight. "Oh, fuck."
"I’m going to cum," Shining said and he was almost out of breath as his cock shot his hot seed into his sister’s womb. The mare was panting and her eyes were closed, her head lolling at an angle, but it was clear that she was taking it all in.
"Holy shit, Shining!" Twilight screamed, gripping Shining's hips as she felt Shining's cock cumming inside of her. "This is the best fucking thing I've ever done!"
"This is amazing, Twilly!" Shining said, holding sister’s hips while he thrust his cock into her.
It was unbearable. Twilight’s body was already so full from her first load that her womb was soon soaked. She needed more she needed more semen, more of his semen. But Twilight’s body was already so full from the first spurt, she could barely move. As the first semen flowed, Twilight’s body grew wetter. She began to pant. But she was already too much for the stallion’s hot seed inside her to hold down.
She felt wetness of his cum on her skin and her womb, and felt herself being filled again and again. Her womb was overflowing, her body filled with his hot, thick seed. She cried out, screaming. Her body felt numb, like it had taken too much cum from the stallion. She felt the same warm liquid filling her with each passing second. But it was not enough. She needed so much more, so much more.
"Brother’s seed is so thick," Twilight said, his voice filled with lust. "You can try harder."
He began to thrust harder and harder into Twilight, into her womb, into her orgasm. He was a living, breathing creature, and he knew how to fuck. As the stallion's cock began to slam into her harder and harder, Twilight's legs tightened on the bed, and her breath came in short gasps. She could feel her womb filled, her womb filled with his seed. She heard the stallion moan as his cock exploded in her again.
She had never felt so full in her life. His cum erupted in her womb, again and again, filling her womb with the raw essence of his seed. Her body was aching with pleasure as she felt more and more of her own cum filling
Twilight was overwhelmed with the pleasure of the orgasm, unable to speak or even breathe as her body tingled and spasmed with the pleasure.
She felt the stallion’s semen dripping down her legs and pooled against the mattress. He was still pumping, his cock still pulsing as he forced more and more of his thick, hot seed into her. She felt herself grow even wet, and her body tensed around him as it felt the pressure of the massive load filling her womb.
Shining Armor’s thick sperm continued to drip out, coating with her milky semen, but the pressure of his semen continued to force more out of her. With no way of escaping his seed, Twilight’s insides became saturated with it. Twilight’s body became quivering with pleasure, as the pressure of her womb filled her with the seed.
She was filled to the brim with semen, and as it dribbled out of her body and dripped onto the floor she felt her insides begin to swell with new vigor. She trembled with new vigor, and her insides began to expand to their full size. Her womb began to fill with new seed, swelling with it. As her womb filled, her insides began to swell to their maximum size. Twilight’s body jerked as her climax came, her womb pulsing with the pleasure of her orgasm. The giant cock of the stallion’s cock was still deep inside of her. Twilight’s moans grew louder and louder as her womb continued to swell like a balloon. The liquid was making her womb tight, tight even to the point of her womb collapsing.
The stallion's semen was now flowing continuously into her, but she felt like it was going faster and faster. Soon her fur was slick with semen.
"Oh Celestia," Twilight gasped as she felt cum start to flow from her cunt. The next thing she knew, she was lying on her back with her legs spread. Twilight quickly pulled her legs up, but the stallion’s semen was still pounding into her vagina. The stallion’s cock slid into her, and his spunk flowed into her, filling her with that same hot, sticky cum.
Her legs started to tremble and her feet began to shake. Her breathing began to become heavier, and her pussy began to clench up and she started to feel as if her womb was going to break.
And then it was over. The stallion’s thick cock left her womb and her body slumped down onto the bed. He leaned forward, and he leaned down back onto Twilight as he licked at her, licking her pussy with his tongue. Twilight was so turned on she barely moved from the position she was in. Shining and Twilight were both panting like crazy, as they fought to keep their arousal from spilling over.
"Oh, Shining, you're amazing," said Twilight with a wicked grin as she brought her mouth down on the unicorn's muzzle. They both knew this was just the beginning, but they both loved the feeling of both their own flesh and their own juices. They were going to fuck like that for the rest of their days. They were going to fuck any pony, any fucking creature, as many as they could. She will bring him so many foals as he will want and even more. And all the world will belong to them.
