My Little Pony: Origins.

Chapter Eighteen.

A Fractured Bond Part I.

February 17th 2015, Ponyville, Equestria. 11:45 am.

Cadence's private train slowly rolled into Ponyville yard, snaking onto a siding adjacent to '43999'. The Electro-diesel multiple unit gently braked to a stop. Rain ran down the windows as the doors opened onto the small staff halt.

"Thank you for taking me to see her, Cadence." David said as he stepped down from the train, pulling up his hood. He looked up at the royal train he had just disembarked from, the blue colours it was painted in were fading, the livery of its previous owner coming through. The train was in a sorry state, not exactly living up to its royal purpose at all!

"David, no need to thank me, you were within your right to see her. You were her father after all." Cadence replied, putting on a hoodie. She stepped down onto the wooden platform, looking up at the sky and smiled as a weight she carried for years disappeared, she was now at peace with the past, "David, i better get going back to Twilight's castle, gonna try and explain this all to Flurry." She added, and explained to David how the others had found out.

"Well alright, but before you go, can i be honest with you?" David asked, Cadence smiled and a nodded, "Well you see, i kind of had a hunch you were pregnant but i never thought much about it."

"Oh really? What gave you this hunch? It wasn't any mood swings was it?" She questioned, frowning slightly.

"No, its just um..." He paused, blushing, "Well your..." He nervously rubbed the back of his head, he pointed at her crotch. She let out an 'oh!' as she understood what he meant.

"Don't worry, you can say it, my crotch tits." She smugly said, making David blush even redder.

"Well, your teats were getting bigger, i just never thought much about it as you were still growing up after all." He chuckled nervously.

"Ah, i see." Cadence responded, giggling at the blush plastered on David's face, "Before i go, let me give you something." She said, pulling the hood over her head.

"Give me what?" David raised an eyebrow.

"This~" Cadence hovered up to his cheek and kissed it, "Thank you." She said before trotting out the yard.


Cadence arrived back at the castle a few minutes later, it was a welcome sight as she run up the steps. She paused, looking over to right at Twilight's School For Friendship. Cadence remembered the day Flurry Heart had started attendance, she was so proud of her little girl that day. The school had closed for the winter and was due to open next week, meaning Cadence wouldn't see Flurry for another six weeks until the spring half term. She had to talk to Flurry Heart, now or never. Cadence threw the doors open, unzipping her hoodie and tossing it to the side. She shook herself off before trotting towards Flurry Hearts room. The long corridor felt unwelcoming, barely decorated, the few decorations consisted of mostly pointed plants and the odd coffee table with a picture frame taking place at the centre. Cadence sighed as words of what she was going to say to her daughter filled her mind. At last, she reached the end of the corridor. She passed through the opens doors, seeing that the kitchen lights were still on.

As Cadence passed the kitchen, she saw Rainbow Dash and Pinkie Pie staring coldly at her. She walked down the corridor, Cadence thought she heard Pinkie Pie talking.

"What's she doing back?" She heard the earth pony say darkly as she climbed the stairs leading to the guest rooms, Cadence sighed as she reached the top.

"Hi Cadence!" She heard Spike shout, breaking her from her trail of thought.

"Oh. Hi Spike..." Cadence frowned, looking down at the carpet. She let out a surprised yelp when the dragon embraced her into a tight hug.

"Twilight told me about Shooting Star." He hugged the alicorn tightly, "I'm so sorry." Cadence rested her head on his shoulder

"Thank you Spike..." She said quietly, sniffing as she pulled away, "I need to explain this to Flurry Heart." She added, quickly explaining how Flurry had overheard her when she was telling Pastel Pen. Spike placed a claw on his chin.

"Ah, i see." The tall drake calmly said, "Well then, i'll leave you too it." He chuckled before tripping over his own wings, "I'm ok!" He added, dusting himself off before walking down stairs, Cadence hid a chuckle as he went out of sight.

Cadence stood outside Flurry Hearts room. She took a deep breath and opened the door. Cadence was surprised to see the room devoid of her daughter, she sat on the springy bed and waited for Flurry Heart to appear. The door that led to the ensuite bathroom opened and out came Flurry Heart dripping wet, draped in a towel, she froze when she saw Cadence sitting on the bed.

"MOM!" Flurry screamed, covering herself with a towel in embarrassment.

"Oh relax dear." Cadence chuckled, patting the bed next to her, "Come, sit down." She added.

"No!" Flurry shouted, "Not after what i heard what you and uncle did." She glared at her dear mother, "I don't want to talk to you!" She protested.

"Sit. Down. Now!" Cadence raised her voice. Flurry instantly trembled in fear, hell hath no fury like an angry mother. Flurry quickly sat at the spot Cadence had been patting.

"S-s-so..." Flurry stuttered nervously, Does she think she's in trouble? Cadence thought, looking at how terrified her daughter looked, Did i scare her? Oh no, did i raise my voice again? Cadence's mind raced at a thousand miles a second, "So... you and my uncle had a fling?" Flurry broke through Cadence's trail of thought.

"Yes, we did." Cadence bit the inside of her cheek, "And, that was the best 17 months of my life." She said proudly.

"But why?" Flurry asked, her voice filling with anger.

"I went into heat, and i chose him to help me stop the burning i felt." Cadence said, "And my god, he was so big, i thought he was gonna rip me in half!" Cadence bit her lip. This caused Flurry Heart to blush madly.

"Mom! Too much information!" Flurry screamed, hiding her face in her wings.

"Hey! You asked why." Cadence said smugly, pulling Flurry Heart to her closer and squeezing her against her chest.

"Seriously mom!" Flurry struggled to breath, "Why did you sleep with him?" She wheezed, breaking free from her mom's grip.

"Ok ok, i'll tell you everything." Cadence said, picking up a mane brush, Flurry turned her back to her mother as Cadence proceeded to brush her mane, "Well, it all started a week after my fifteenth birthday..."


Cadence awoke feeling rather hot and sweaty. She looked over at her bedroom windows, expecting them to be closed, thus explaining why she felt so hot, to her surprise, they were wide open with a strong breeze blowing through.

"Why am i so fucking hot?!" She screamed into her pillow, throwing off her sheet as she left her bed. Cadence pulled the large fan from her wardrobe. She placed it right next to her bed, plugging it in and setting it to full. She pulled down her shorts, flinging them to the side. She wriggled out from her t-shirt as it clung to her sweaty back, she tossed it over the bedknob. Wearing nothing but her white panties, she threw herself onto her bed, laying on her chest. The young pegasus's wings unfolded at her sides as the breeze rushed over her damp feathers. She felt a chill run down her spine, the fan cooling her back.

"That's much better..." She said as she succumbed gently to slumber.

Cadence woke nearly an hour later, panting and sweating as she struggled to get out of bed, the sheet sticking to her.

"What the hell is going on with me today?" She questioned herself as she pulled a towel from her wardrobe, draping it over her back. Cadence slipped her panties off as she opened her bedroom door, she quickly ran across the hallway and into the bathroom before anyone could she her. Her hooves clip-clopped against the tiles as she slide open the glass shower door. She turned the cold tap, wincing as the ice cold water landed on her back.

"This'll cool me down for sure." She said to herself, grabbing a shampoo bottle from the window sills. She shut the shower door, placing the bottle on the shelf next to the shower gel. Her messy mane stuck to her wet fur, water trickling down her face. Cadence ran her hooves through her mane, making sure every inch of her elegant locks were wet. She lent over and and grabbed the shampoo bottle, flicking the cap and smelt it.

"Ooooh! Strawberry and Mint!" She squealed in delight, squeezing out some of the syrup like substance onto her hoof. She rubbed in the shampoo while placing down the bottle, she ran her hooves vigorously through her mane, every inch of her extremely long mane slowly being engulfed in bubbles.

Cadence emerged from the shower a few minutes later, quietly sneaking into her room unnoticed. She slipped into her slippers as she shut her bedroom door behind her. The mattress sunk down with a squeak as her rump made contact with the silky fabric. She stretched out her legs, drying herself off with a large cotton towel. Cadence made sure she was completely, making her way over to the chest of draws. She pulled out a pair of panties, pulling them up and over her flank, her tail popping out through the hole cut in the back. She trotted over to the wardrobe and pulled out a blue shirt and a red one, looking in the mirror, making a choice on which one to wear.

"I think blue suits me today." She said, removing the chosen item from the hanger, her wings popping out of the custom made clothing as she pulled it over her torso. Cadence put on a matching pair of shorts, tying them up tightly.

As Cadence began brushing her mane, she once again felt herself burning up again despite sitting right next to the fan.

"Oh! You gotta be fucking kidding me!" She screamed in anger, no idea why she kept feeling hot, "How can i STILL be hot?!" She threw herself onto her back, punching her pillow in frustration, "Unless... No. Can't be, i can't have a fever, i would of gotten chills and i would be arching." She questioned herself, placing a hoof on her chin, "Although, i wouldn't hurt to get a second opinion." She looked over at the clock sitting on the bedside cabinet, "David would be up right now..." She frowned, remembering the fight she had with her brother the night before. Cadence groaned as she sat up right, slipping off the bed and exiting her room.

Cadence trotted down the stairs and turned left into the kitchen, she rummaged through the draws for a thermometer, but came up empty hoofed.

"Looks like i'll have to ask David to check my forehead..." She paused, "But what if he's still mad at me?" She questioned herself.

"I'm not mad at you." Cadence jumped in fright at the voice behind her, she looked down from her hiding spot above the refrigerator to see it was David.

"You're not?" She leaned her head over the edge.

"No i'm not." David said, raising a hand to her cheek, "Now, get down please.", He added, raising both arms. Cadence wriggled over the edge, David catching her, his hands gripping around her waist. Cadence smiled as she felt her hooves touch the floor.

"Thank you sir David! You have saved your princess from the evil Fridg Rator!" She chuckled while faking a royal voice.

"What are you doing up at this time anyway?" David asked the teenager before him, causing her to frown.

"I couldn't sleep." She moaned, "I think i have a fever. David, can you feel my forehead?" She said, her hoof lifting her fringe from her head.

"Sure." He replied, placing his palm flat on her head, he frowned, "You're not even hot." He added, this confused Cadence even more.

"Are you sure i'm not a little hot?" She raised an eyebrow, putting his hand back onto her forehead.

"No, you're barely warm." Cadence frowned even more.

"This doesn't make any sense." She replied, placing a hoof on her head in annoyance.

David put his hand to his chin, "Tell you what, you go into the front room and i'll fix us up some breakfast, then we can talk about what's going on." He suggested, Cadence nodded eagerly, quickly trotted down the hallway. David simply shook his head and chuckled.

David returned from the kitchen some time later carrying a tray with two plates and two glasses, he sat the tray down on the carpet between the sofa and the tv.

"Hope you're hungry." He said, turning around only to see Cadence laying on her belly on the armchair, preening her wings, "Well then looks like more pancakes for me." He smirked. Cadence looked up mid preen, her tongue sticking out slightly.

"Did you say pancakes?" Cadence spoke, spitting out a feather. She quickly scuttled off the chair and sat next to David, eating the stack of deliciousness before her.

"So... What's the matter?" David said, wrapping one arm around Cadence, making her blush. She looked up at him and smiled.

"Well... I woke up feeling like i was burning from the inside. I thought it was my room but even with the the strong breeze blowing in from the bay and the fan, i was still roasting! I even had an ice cold shower for fuck sake! And even that didn't work!" She ranted, pausing to take to drink from her glass, "I honestly have no idea what to do!" She slammed the glass down.

"Hmmm." David let out while in thought, "Doesn't sound like a fever or any illness i've heard of." He added, this caused Cadence to pout, her ears fell flat against her head.

"Well that doesn't help my situation in the slightest." She crossed her front hooves in disappointment.

"Tell you what." David said, "I have to drop some books off that the library, you're welcome to join me. We could have a look through the science books and see what matches up with that you told me." He added.

"Ok..." Cadence slowly nodded, finishing the late of the pancakes. A few minutes later, the pair were walking up to David's car, Cadence opened the passenger side door and sat down in the seat and shut the door, strapping herself in as David sat down in the drivers seat.

"Ready to go?" He said, placing a carrier bag of books in the footwell on Cadence's side. His sister nodded glumly, "Rightio." He said, turning the key, the engine roared to life as he strapped himself in. The ex-rally car hummed out the driveway, barreling down the road.

Before long, Cadence and David arrived at the library. Cadence grabbed the handle of the bag in her mouth as she stepped out the car, closing the door behind her, David followed suit, locking the car with a buzz. He took the back from her as she sprinted up the steps.

"Come on David!" She impatiently stomped her hooves on the concrete steps.

"I'm coming." He said, quickly walking up the steps, "I just had to double check i locked the car." He added, stopping at the top of the stairs, Cadence sat at his feet, looking up at him and frowning, "What?" He asked her, she continued to frown.

"I really want to find out what's happening to me!" She raised her voice, David held his hands out in defense.

"Hey hey hey, no need to shout." He said walking past her and opening the Library door, "You coming or what?" He asked, Cadence stood up and followed him, the door slowly closing behind them.

David approached the returns box and put the books inside, Cadence rushed past him, running towards the biology section, her hooves sliding on the laminate floor as she turned the corner. David calmy tracing the young pegasus steps through the building, finding her surrounded by science books.

"No, no, no, no. Argh!" She slammed her hoof down on the table before repeatedly hitting her head on the oak surface, "This. Is. Hopeless!" She said, rubbing her now sore head as David stopped behind her.

"It's not hopeless." David said, placing a hand on her shoulder, "You just need to know where to look." He added, spotting a computer out the corner of his eye, "Hey, why don't you go on that computer while i put these back." He suggested, picking up all the books Cadence had got out and placing them onto the correct shelf while she slowly trotted over to the computer, sitting down at the desk. She looked over at the people on the overside of the desk typing away at the other computers, she looked behind her, seeing people reading books at desks.

"Scooch over then." Cadence was startled, turning her head around in surprise, to her relief it was just David, She moved her chair over, allowing him to place a chair in front of the computer.

"Right then." David said, sitting down next to his adoptive sister, she look at him, her mane covering her right eyes, she batted it away, "So, you tell me what you were or still are feeling and i'll type it on here and we'll see what comes up." He said, turning to her. She smiled nervously, looking down at her shirt, the dolphin made from sequins sparkled in the light emitting from the computer screen, "So, you ready?" David asked her, she nodded.

"Well, i firstly felt like burning up from the inside." She said, David typing down hot flush, "I was also feeling slightly aroused." The keyboard tapped with every keystroke, "And..." Her face went red.

"And what?" David turned to her, she took a hard gulp, she gestured him to bring his ear closer, she whispered into it, David blushed, "I see..." He stuttered, quickly typing down what she said, "Ok, according to his, you are in estrus."

"What?" Cadence asked in confusion, she had never heard this word before, even in science class.

"You're in heat." He added, she raised her eyebrow, now even more confused, "You're in season, you know? Like a dog or cat." She let out a gasped, she now understood completely.

"So then." Cadence looked at the screen, "Does it say how i stop it?" She asked, trying to use the mouse with her hoof.

"It says here that there are two ways to combate a mare in heat, option A is to keep her isolated from any stallions for the 4 days under the estrus ends or B is to breed her." David said, looking at the screen. Both his and Cadence's faces squished together.

"Breed? Like what?" Cadenced asked with confusion.

"You know..." He said, looking left and right, "Have sex." He whispered, both his and Cadence's faces went red. They pulled away from each other awkwardly, she turned her ice blue eyes away from him.

"We should be getting home." Cadence said, stuttering like mad. She nervously rubbed the back of her neck.

"Yeah..." David said, closing the internet program before getting up from the desk.

The pair left the library some time later, David pulled out his car keys with a clink, he looked down at Cadence, she had been surprisingly quiet since discovering she was in heat.

"You ok?" He asked her, she looked up and smiled weakly.

"I'm fine, just thinking, that's all." Cadence waved her hoof as David unlocked the car, she opened the door and back down in the seat, shutting the door before buckling herself in.

"Thinking about what?" David asked said as he sat down in the car, turning the key in the ignition. This question brought a blush to Cadence's face.

"None of your business!" She shouted, David just shrugged as he brought the car out the parking bay, unknowing of a plan Cadence was slowly hatching to put an end to the burning sensation she felt every second.

They soon arrived home, as David's car pulled in to the driveway, they both saw Jessica and their mother putting bags into the other car.

"Looks like they're getting ready for the big monthly shopping trip to Nord Bridge." David said, turning the car's engine off. They stepped out the car, walking towards the other two.

"Oh there you too are." Rose said, shutting the car boot, "So, where did you two go off to.?" She raised an eyebrow.

"I went to the library to drop of the books Jess had took out, and Cadence asked to come with me." David said, Cadence sighed quietly in relief.

"I see." His mother replied, "Well, me and Jess are about to leave for Nord Bridge, you want to come with us." She said, Cadence's eyes widen, now was her only chance.

"No. David said he'd help me put some stuff into the loft" Cadence blurted out, pushing David towards the front door.

"Oh, oh ok." Rose said as Jess got in the car, she looked at her watch, "We should be back by about 1:30 - 2:00." She added, opening the car door, "Be good you too!" She said, getting in the car.

Cadence waved to them as the car rolled out the driveway.

"Have fun!" Cadence said as the car rolled down the road, she shut the front door, "Good, i thought they'd never leave!" She purred, forcing her mouth onto David's. He pushed her off, wiping his lips.

"Cadence! What the hell are you doing?!" He shouted, she frowned at him, slamming her rump down on the carpet.

"Fuck me David~" She lustfully said, pulling off her shirt, exposing her fluffy pink chest, "Fuck my pink pony pussy." She started to undo her shorts.

"Let me stop you right there. No. I am your brother and even if i wasn't, you're 15, it's statutory rape, even if it's consensual." He added, throwing her shirt back at her. He frowned at her as she pulled her shorts off, flinging them at him, her crotch was soaking wet with a sticky trail running down her thighs.

"I want your cock inside me. My body yearns for it. I need it!" She screamed, turning her rump to him, her white panties were soaked, "You can smell my scent can't you? It's intoxication isn't it? Go on. I won't bite." She purred, her wings folding .

She let a squeak when she felt his hands wrap around her waist, "Good lad." She said before seeing him walk past her, "HEY!" She screamed, chasing him, "I want you to pop my cherry!" She shouted, flailing her hooves around.

"No you don't." David said, causing her to frown, "Hey, why would you me to do it anyway? I'm not a jock, i'm not some badass. I'm not anything worth paying attention too." He said, walking up the stairs, "I'll speak to you once you've calmed down." He added, shutting his bedroom door behind him.

"I will get your cock in me." She put her shorts back on, "If its the last thing i do." She grabbed her shirt.

David sat in his room, trying to listen to music for the past hour, Cadence had sat outside his room repeatedly asking for him to fuck her, to which he'd always reply with no. He paused the music, expecting to still hear her at the door begging, but to his surprise it was silent.

"Hmm, must of got bored of asking. Good. That means i can go at get something to eat." He said, putting down his pencil. He walked over to the door and opened it looking left and right.

"Please?" He heard her ask, looking down, he saw her sitting like a cat, her tail curled around her.

"No!" David slammed the door in her face, she frowned.

David quietly snuck out his room sometime later, he quickly made his way into the kitchen. He make himself a simple cheese sandwich, he made his way to to the front room, sitting down on the arm chair.

"Sandwich. Moist and delicious." He said, taking a bit from it as he looked out the window, watching the beach.

"You wanna know what else is moist and delicious?" Cadence appeared behind the chair, nibbling on David's neck, "Why don't you follow me to my room and find out?" He stood up in surprise

"That's it!" David shouted, grabbing his slipper and throwing it at Cadence, hitting her square in the face, she fell back onto the sofa, acting like she was shot, "Grow up." He groaned, she sat up and frowned.

"Well excuse me~" She said, wrapping her tail around his waist as she stood up on her hind legs, "But i want you inside me~" She purred, stretching up her neck to trying and lock her lips with his, he pushed her down.

"No way Cadence. We are not having sex. End of discussion!" He raised his voice, looking down sternly at her.

"Oh... I see..." She looked down before standing back on all fours, she turned away from, "If that's what you really want. I'll leave you be. I'll just go back to my room, alone, and lay on my empty bed." She sniffed, trying her best not to cry. David just watched her leave, slumping on the armchair, he held his head into his hand.

It had been nearly an hour since David last saw Cadence, he hadn't seen or even heard her all during that time. He walked up the stairs, where he heard sobbing coming from her room.

"Cadence? Are you ok?" David asked, trying to open the door but was stopped by something heavy behind it, "Cadence, open the door." He jiggled the handle.

"No..." She sobbed into her legs as she sat behind the door, "Go away!" She screamed, hitting the door in anger.

"Cadence..." David said, sitting down on his side of the door, "Look, i'm sorry i shouted at you. You know we can't have sex even if your weren't my sister, you know the law." He said, resting his head on the oak door.

"I know, but we aren't related biologically." She said, sniffing, "And all the girls at school brag about have sex, even the ones younger than me..." She said, hiding her face in her wings, "Please David, i want it..." She added, crying again on the last part. Hearing this broke his heart, he was meant to look out for his sister, it was his duty to make her happy, even if it means doing the wrong things for the right reasons.

"Ok... i'll do it." He said, he heard Cadence, sniffle, "Just please stop crying." He added, placing his hand on the door.

"What did you say?" She weakly said through the tears as she looked up, her eyes were red and sore from crying.

"I'll have sex with you." He said, "Now please open the-" He fell over as the door opening behind him, he ended up on the floor looking up at her, "Hi." He smile nervously.

"Hey~" She said, leaning down and nuzzling his cheek with her muzzle, she licked him slightly in the process, "Do you really mean it?" She asked.

"Yes, if it makes you happy." He said, nodding slightly as he sat up, Cadence let out a squeal before hugging him tightly.

"Oh thank you thank you thank you!" She squeezed him tightly, releasing him, she locked her lips with his before dragging him into her room fully, gently kicking the door shut behind her. She flew over to the window, shutting it and closing the curtains, "Now then. Where were we~" She purred, throwing David onto her bed.

She turned away from him, making sure her rump was in his line of sight as she pulled down her shorts, kicking them off her leg, she then pulled off her white panties, flinging them onto the bed post. Her marehood was now on full display, allowing David to see it in all its glory. She turned back around, she leant down and wriggled her rump in the air before pouncing.


"And we then did it for close to an hour." Cadence concluded as she finished brushing the back of Flurry's mane.
"So." Flurry Said, turning to her mother, "It was just meaningless sex?" She almost sighed in relief.
"Well, it did start out like that, but its charged after my christmas prom." Cadence said, brushing Flurry Heart's fringe
"Um... Whats Christmas?" Flurry asked in confusion.
"It's the human version of Hearths Warming." Cadence said, she put the brush down on the bed.
"Why did it change?" Flurry Heart asked as she tried to tie the bow for her mane.
"I'll tell you once we're done here, ok?" Cadence smile, Flurry nodded eagerly.

End of Chapter Eighteen.
