3 Years Ago

The sky above Canterlot was gray with storm clouds as the rain poured down. In the middle of the downpour sat a quaint city house, home to the Sparkle family. As the weather raged outside, the parents, Twilight Velvet and Night Light, slept peacefully in their bed. Their children, however, were not asleep. In fact, they were both wide awake and were both sitting in bed together. Peculiar noises could have been heard coming from the room had the parents been awake at the time to hear them. 'SLURP, SHLICK, SMOOCH'. The sounds were from Twilight Sparkle sucking on her brother Shining's thick, black cock in his own bed.

Twilight and Shining had an interesting relationship, one that their parents were quite oblivious of. It started out small; A kiss on the cheek here, a grope of the thigh there, but it eventually evolved into stronger emotions. Soon, the siblings were sneaking kisses on the lips, dry humping when backs were turned, and experimenting with each other's bodies. They would sneak into each other's rooms at night and masturbate together or Twilight would jerk her brother off, but they never did more than the surface stuff, not daring to go further.

'GLUKK GLUKK GLUKK' Those were the sounds filling the quiet household as Twilight serviced her brother. As she bobbed her head up and down at a slow and steady rhythm, Shining softly moaned into the air. "Fuuuuckk. Twily, how do you always h-hit all the right sp~ohh~spots?" Shining groaned.

Twilight slowed to a stop, pulling her muzzle off his slippery cock and giving the tip a quick kiss. "I don't know BBBFF, maybe I'm just a fast learner. Or maybe you're just too weak for your little sister?" Twilight smirked before opening her maw and devouring his cock once more. Shining scoffed but said nothing, opting to sit back and enjoy his sister's tongue work. Twilight looked up into his eyes and their visions locked together. There was passion in their gaze and it fueled them both on. Twilight began to bob faster, moving her tongue around his shaft as she went up and down. Shining on the other hoof, began to lightly buck up into her descent, pushing his cock deeper into her throat.

As they sped up, Shining moaned Twilight's name. With Shining hammering his cock into her maw, Twilight soon felt his dick begin to throb wildly. It flexed as the increased size clogged her throat, and she loved every bit of it. They both knew how close he was, so they went even faster. Shining pistoned into her wet throat as fast as he could, threatening to blow at any moment. He glanced down at his sister and caught her eyes once more. They had done this enough times to know what certain faces meant, and the one she had on now had one clear meaning: Cum for me, bro! Shining placed his hooves on Twilight's head, forcing her down as he made one final thrust into her maw. Hilted completely in her mouth, Shining's cock erupted with pleasure. "Gah fuuck! Take it all Twily!" he whispered, trying desperately to not wake their parents.

Boiling hot cum raced through Shining's cock and blasted into Twilight's throat. Shining held his sister down as he filled her mouth with his essence, his hooves twitching from the overwhelming pleasure. Twilight began to gulp down her brother's sticky seed, taking the time to taste every drop. She sucked and licked as she was forced down, moaning deeply throughout the experience which resonated through Shining's cock. As Shining's bucks became less frequent, he started to teeter off before finally going limp inside his sister's glorious mouth. Twilight slowly lifted her head, pulling his cock out of her mouth with a pop. She swallowed what was left in her mouth and smiled deviously at her worn-out and dazed-looking brother. "Mhhm, just what I needed tonight. A creamy, sticky treat all for me hehe. You were amazing bro-bro, as always." Twilight licked her lips before snuggling up next to her brother.

"Yeah...that felt incredible sis. Now come here." Shining said. Still seeing stars, he lifted Twilight with his hooves and placed her beside him in bed. He planted a kiss on her forehead and then her cheek before shifting under the covers.

"I love you BBBFF....." Twilight said before she slowly drifted off to sleep beside him.

Shining covered her up with the blanket and closed his eyes. "I love you too sis." As he lay in bed he thought to himself. 'Can we keep doing this? What if we get caught? Could this ever be...more? No...I shouldn't entertain the thought...I don't want to hurt her.' Those were Shining's last thoughts that night before he swiftly drifted off to sleep as well.

Present Day

Princess Twilight was busy all morning and into the evening. She was expecting a visit from Shining and Cadance and wanted the castle to look its best! She flew around corners, swept cobwebs up in her magic, wiped down the windows, and organized the library. Everything was ready for their arrival, and so was she. The two siblings had not fooled around for a while and both were anxious to feel each other again. Celestia had just started to set her beautiful sun when the doorbell went off with a ring, echoing through the corridors. Twilight smiled widely and raced to the entrance. As she threw the doors open she was met face-to-face with her brother and sister-in-law. "Ahh, you're finally here!" Twilight shouted as she nearly tackled Shining to the ground.

"Woahhh, easy there sis! I'm not indestructible you know." Shining hugged his sister back, a bit tighter than most would. As they hugged, Twilight felt his sheath brush against her and she nearly yelped, but she quickly withdrew from the hug without raising suspicion.

Twilight soon walked over to Cadance as they began their little dance, both singing their iconic song. "SUNSHINE SUNSHINE, LADYBUGS AWAKE! CLAP YOUR HOOVES AND DO A LITTLE SHAKE!" Both mares chuckled as the dance ended and they hugged each other closely. Shining watched as they hugged, but his focus soon shifted to Twilight's flank. He felt his cock twitch as he ogled her form. He quickly snapped back to reality and joined in on the hug. The three royals soon let go of each other and headed inside.

"Oh, it's so nice to finally have some time together! I've missed you both so much." Twilight said.

"We've missed you too, Twily. It's nice to spend some time outside of the throne room. No more meetings or papers to sign. Feels good to relax for a bit. Plus, Sunburst is watching Flurry while we're gone so we didn't even need to find a foalsitter." Cadance replied.

As the trio made it to the foyer, Twilight turned with a perplexed expression on her face. "Well, I didn't have anything exactly planned and Spike is staying at Sweet Apple Acres for the weekend, but I can whip up something for dinner later if you two want to relax?" Twilight winked at Shining with the word relax, a sultry gaze crossing her eyes. He knew all too well she wanted him, badly.

"You know what? How about we settle in early tonight instead? We can eat a big breakfast in the morning to make up for it. Sound good dear?" Shining asked, looking to Cadance.

"Sure, fine with me hun. I'm beat from the train ride anyways." Cadance yawned to express her point.

"Alright, it's settled then. Hun, why don’t you bring our stuff up to the room? I wanna talk with Twily a sec." Shining asked.

"Sure, sweetie." Candace replied. She grabbed their baggage in her magic and headed up the stairwell. When she made it to the top and rounded the corner, Shining dashed toward Twilight and scooped her into a deep kiss.

"I missed you...so fucking much." Shining said in between sucking on her velvet lips. As the two kissed they rarely came up for air. They groped each other, ran their hooves down the other's body, and soaked in the emotions. Soon they released and stood back. "I'll meet you in your room tonight. Why don't you go get ready for me?"

Twilight blushed. "~You got it BBBFF.~"

They shared one last kiss before heading to their respective rooms for the night. While Shining talked to his wife like nothing was going on behind the scenes, Twilight was getting her room ready for another lustful night with her dear brother. As Luna's moon rose into the sky, Shining was getting anxious. "Hey honey, I think we should hit the hay. Don't want to miss breakfast." Shining said, looking at the door intently.

"Alright sweetie. Just one thing I wanted to ask you though before hoof. Have you and Twilight had sex yet?" Cadance asked bluntly.

Shining's heart skipped a beat and he choked on his spit. "WH-WHAT!? Shining looked stunned at his wife, who looked none too concerned at the question's premise.

"You heard me quite well, dear. Have you, and her, fucked yet? It's a very simple question." Cadance said with a little raise of her eyebrows.

"Ca-Cadence, you're not..." Shining tried to reply.

Candance looked at him with her annoyed but sultry eyes and said, "Oh, don't give me that half-flanked excuse! I've KNOWN about what you and Twily have been doing behind the scenes for quite some time now, so stop lying to me!"

The stallion blushed. He was speechless. He thought of his next words carefully as the pink mare continued to smirk in front of him. Rather than fruitlessly deny it any further to the mare that he lovingly married, he begrudgingly admitted the truth. "Alright, fine....N-no, we never dared to go further. I mean, we've fooled around a bit but we never went that far... B-but wait, that doesn't explain how you found out about all this!? Or why you're so unnervingly calm about this..."

Cadance looked appalled. "Shining Armor! Do you not remember that I am the Princess of Love? All matters to do with romance, attraction, and lust, I can sense down to the smallest detail. I have known about your feelings for each other ever since our wedding for Celestia's sake! Don't think I didn't know what was really going on when you and Twilight headed up to the bedrooms to 'chat' that night. Now, please stop lying to my face."

Shining thought in stunned silence for a moment. "O-okay, but that still doesn't explain why you asked...that. I thought you would be furious if you found out about me and Twilight!"

"Oh, Shiny. You can be so dense sometimes. I will admit I was confused, the first time I felt your auras. It wasn't the first time I had felt such feelings show themselves in ponies, mind you, but yours and Twilight's auras were...different. Instead of just feelings of lust and passion, what I sensed was far more intimate. I sensed true, unwavering love. You and Twily have such a deep, loving bond, that it's hard not to want to let it flourish! I sense it every time you two are around each other, and the love continues to grow every time you two meet up. It's as strong as the love we feel for each other, if not stronger. Let me ask you this dear: Do you love Twilight? And I mean, more than as just your sister?"

Shining didn't hesitate. "Of course! I love her so much. I feel like she completes me in a way, just like you do."

Cadance smirked again. "Then why are you hiding this from me? Why haven't you taken it further? Shining, I can tell she wants to take it to the next step as much as you do, but she is too afraid to take it in fear you will disapprove. It's up to you to show her how much she means to you..."

Shining looked at her with a puzzled expression. "Wait, you mean...Twily wants to have sex with me?"

"Hmmm mmhh. She wants you so much Shiny that it's eating away at her. I know you'll be the first to bring up my feelings in this, but tonight is all about you and your sister. I've been waiting for this moment for a long while, and I think it's time you do something about it mister." Cadance said before her magic flared up. She picked Shining up in her aura and opened the door, floating him out into the hallway and setting him down.

"Woah-woah what are you doing!?" Shining asked cautiously.

"I'm making sure you go give Twily the love she truly deserves! Now, be a dear and go ravage your dear sister for me." Cadance grinned mischievously. As Shining stared at his wife she leaned in to whisper in his ear. "Oh and honey, I want you to give Flurry a cousin or two. Have fun!" Shining could only gawk as she closed the door behind him. Running those last words through his head, Shining could feel his cock begin to twitch and throb. Seeing no way out of it though, Shining got to his hooves and started toward Twilight's bedroom, all the while lost in his lewd thoughts.

Twilight, meanwhile, was lying in bed. She had dozed off to sleep facing the door, the bedroom littered with rose petals. She had put on purple lipstick for their special night and wanted to be romantic, for what it was worth. As Shining approached the door, he thought about all that Cadance had said. 'She really wanted this? She wanted to go the extra step with him?' These thoughts were pushed to the back of his mind as he opened the door and stepped inside.

Shining gulped as he spotted Twilight on the bed and stared at her with wonder. 'She's so beautiful.' Shining thought. As he stared, images flashed through his head. Images of Twilight lying next to him with a swollen stomach, of him kissing up her neck and of a beautiful foal or two soon to be born from their union. He looked at Twilight's body and imagined all the things he could do to it. He had made up his mind. He wanted her so much and she wanted him. He was not going to deprive her of what she wanted any longer. He could only hope to please her desires...

Shining slowly approached the bed, coming up to Twilight's side. He did not want to jolt her awake, but slowly ease her into it. As he stood in front of her, he leaned down and started to kiss her neck. Twilight stirred as he continued, before she slowly opened her eyes. "You're here. Did you give Cadance the slip ~he he~?" Twilight asked, still slightly droopy.

Shining placed a hoof under her muzzle and pulled her mouth to his. The kiss was full of passion, and neither wanted to release the other from it. Soon enough though he pulled away and smiled at her as she sat up in bed. "Not exactly sis. Look....Cadance knows about us. She knows what we've been doing behind her back."

Twilight's face turned to a mix of confusion and horror. "W-what!?"

Shining quickly de-escalated her concern. "It's okay, it's okay! She's not upset. She told me tonight that she has known about our relationship for quite some time now....."

Twilight looked even more confused. "So...she knows what we've been up to? And she is NOT mad at us??"

Shining shook his head. "No, she's not mad. In fact, she seems quite happy with our relationship. She told me she can sense emotions, even deep-seated ones like what we have. She says that every time she sees us, we give off so much passion that it's hard to ignore." Twilight slowly nodded before he continued. "She said she could feel your emotions emanating from you, and that you wanted something from me......Twily, is it true that you've wanted to have sex with me?"

Twilight was taken aback by the comment, but soon looked down at the bed with a deep blush. "M....M-maybe, a few times."

It was Shining's turn to blush. He sat on the bed next to her and wrapped a hoof around her. "Twilight...I-I never knew you wanted....."

Twilight looked him in the eyes. ".....I was too afraid. I was afraid you would think it was too much or too blunt. I didn't want to be pushed away." Twilight started to tear up before Shining pulled her into a hug.

"Twily, I would never do that to you! You know I would never push you away. I love you, more than as just a sister. I will always love you no matter the form it takes." Twilight smiled and hugged him back.

Twilight's eyes lit up. Shining could see her mulling something over in her head, but it did not take long for her to squeak out what she wanted to say. "Shining...I want more than just to have sex with you. I...I want to have your foals!"

Shining was stunned. 'So Cadance wasn't too far off...' "I...I don't know what to say Twily. I mean, I'm not opposed to it, but are you sure you want this?"

Twilight blushed. "Yes. I want you so much Shining. I want to bear your foals. Please, I want this more than all the books in my library. So......what do you say, BBBFF? Will you give me a foal to love and cherish?"

Upon hearing her response, Shining didn't hesitate as he flopped onto the bed with a smile, pulling Twilight down on top of him. He pulled her into another kiss, much slower and more sensual than the earlier ones. As they made out, Shining moved his hooves up and down Twilight's flanks. He squeezed her thighs, massaged her sides, and felt up every inch of his sister's beautiful violet body. Shining broke the make out session and kissed down Twilight's neck as she moaned softly into his mane. Twilight's mind raced with pleasure, eagerly awaiting the moment her brother would claim her like she had imagined!

"Alright you hunk of a stud, let's get your friend in the mood~." Twilight sat up and pushed Shining onto his flank. She lowered herself down toward Shining's groin before stopping just above his already growing cock. She admired its size and length, like she always did, but she almost fainted at the thought of it soon ramming her insides! Twilight leaned forward and started planting soft kisses on the dark black flesh, her lipstick leaving faint violet markings. She savored the feeling of each pulsing vein as it touched her lips breathed in his musk. It drove her wild!

Twilight moved a hoof to his cock and wrapped it around the pulsing shaft. She slowly massaged it up and down, matching the rhythm with Shining's moans. As she jerked him off she continued to plant kisses all over his cock and balls, leaving marks everywhere. She brought his nuts into her mouth as she sped up her hoof movements, jerking him at a steady pace.

"F-fuck, that feels amazing Twily. Did you learn some new tricks since we last did this?" Shining smirked.

Twilight didn't respond. She kept her eyes locked on Shining's cock and balls, licking and sniffing as she jerked him off even faster. She moved her other hoof to his member and squeezed it between them, increasing the pressure and sending Shining spiraling in pleasure. Her hooves were like velvet silk as they glided effortlessly up and down his toned flesh.

Not wanting to leave his dear sister hanging, Shining lit up his horn. A small orb of purple magic formed in front of him, which he then moved down toward Twilight's winking folds. Shining maneuvered the orb as he rubbed it against her clit, earning a cute squeak from the horny mare. Shining rubbed her lower lips at the same pace as her jerking movement, keeping perfectly in rhythm with his dear sister.

Twilight moaned as she ran her tongue ever so slowly up Shining's cock. She suckled on his cock tip, drawing out his savory pre-cum and mulling it over in her mouth. Her movements were erratic as her tongue moved to his nuts. "Come on, big bro! I know you're so close. Give it to me!" she said, her words drowning in lust and desire.

Both ponies soon felt it. They were both about to cum. As Shining continued his lavish assault on her lower lips, Twilight replaced her hooves with her mouth, blowing Shining with a frenzied look in her eyes. Shining's magic proved to be Twilight's undoing as she suddenly came, squirting onto the bed and staining the sheets. Shining had reached his limit, and tried to blurt out, "I-I'm going to c-ahhh!" before he ripped his magic to Twilight's head and held her down on his cock. He bucked wildly into her mouth as the flood gates opened and a stream of sticky, hot whiteness flowed out from Shining's cock. He bucked deeply and sensually into Twilight's maw as the lavender mare swallowed gulp after gulp of her brother's essence. Twilight's pupils turned into hearts and for a moment she thought she would pass out. Twilight's demeanor quickly recovered as she continued to drain her new lover of all he had. Shining continued to weakly thrust up into her maw before slowly teetering off. Twilight popped his cock out of her mouth and it fell limp onto his thigh.

Both ponies sat back in bewilderment, breathing heavily as they waited for their euphoria to dissipate. Shining was the first to speak. "Hah, huh, that was, something else. Twily, you were amazing! That was so much…more, than usual. Where did you learn to do all that??"

Twilight snapped out of her bliss-induced trance and looked at her bewildered brother. "I uh....I mayyyy have practiced a bit with some old erotica I found around the library....hehe. It's just, I wanted to be a good lover and those old sex books taught me things I never would have thought of. But, I see it paid off better than I expected." Twilight smirked. It was Shining's time to smile as he pulled Twilight into a hug. He kissed her forehead and went in for a kiss on the lips before stopping himself from making a big mistake. Shining held Twilight to his chest and sighed deeply, snuggling into her petite form. Twilight did the same, opting to rest her head under his chin.

While sweet, the gesture was short lived as Twilight spoke up. "Well, what are we waiting around for? ~You said you'd give me a foal and I plan to get one tonight Shiny.~"

Shining kissed her cheek again. "I want this just as much as you do. I want to go all the way with a mare that I love so dearly. But uhm, I'll need a minute before we continue." Shining said with a slight wince.

"Oh no, I'm not going to sit here and wait. I have a better idea." Twilight sat up and lit her horn.

As Shining watched, many different symbols floated from the mare's horn and hovered over his flaccid cock. As each symbol fell into place, he felt a surge of energy shoot through his crotch, reinvigorating him with each flash. When the final symbol appeared they all combined and raced into his now very erect cock with a flash of light! Shining looked down at his cock. It was as hard as diamond! He felt his balls ache, and he could feel the veins throbbing to his heartbeat. "Woah! What did you do to me??!"

Twilight gave a slight laugh. "That book didn't just tell me how to please a stallion...it also gave me some new spells to work with. The spell I just cast increased your libido by quite a bit. It also raised your virility and stamina. So? What do you think? Do you like it?" Shining didn't respond. He sat there, still, looking at his cock as it twitch with each aching throb. Twilight looked concerned. "S-Shiny? Are you okay? I-is it too much, I can release the energy if you wan-" Twilight wasn't able to finish her sentence before she found herself being grabbed and rolled over onto the bed. Shining had twisted his body and snatched her in his hooves before turning around and pinning her to the bed beneath him. Twilight looked up in awe and saw something she had never seen before. Shining Armor's demeanor was ripe with carnal lust. His eyes looked predatorial and his breath was hot and heavy. His cock throbbed as it hovered mere inches away from her marehood's sopping entrance, and all she could smell was the desire and passion emanating off her brother. Neither could speak for what seemed like hours, only for Twilight with hearts in her eyes broke the silence. "S-Shining?"

Her voice snapped the stallion out of his trance. He looked down at Twilight, at his cock mere inches away from her most precious depths. He looked her in the eyes and spoke. "Twily, I love you sooo much. I will always love you. I want to make you one of the happiest mares in Equestria, but I don't want to hurt you. Are you sure you want this?"

Twilight's eyes began to tear up. "Shining, of course I want this. I said I wanted your foal and I wasn't lying. I want you to claim me. You're not going to hurt me. I will admit, I've...experimented with some toys in the past heh. I'm not as fragile as you think. So please, Shiny.....~Take me and make me yours.~" she whispered sensually.

With that confirmation Shining didn't hesitate. He lined his erect cock up to her entrance and both ponies moaned as the battering ram-like tip pushed against her folds. Twilight whimpered as she felt the cock tip ever so slowly begin to separate her folded lips. Shining leaned into his sister, trying to push through that last barrier before suddenly breaching her lower lips and slipping inside. Twilight screamed with pleasure and Shining was taken aback by the sheer tightness of her cunt. She was far warmer and far tighter than Cadance, and just as wet. Shining soon found his ground and pushed further into her sacred area. As he moved he moaned Twilight's name, going ever deeper into her pussy. Just as he was about to stop his cock rammed into the end of Twilight's cove, hitting her cervix. He had hilted entirely inside Twilight. The feeling was like no other. With Cadance's bigger form he could never hilt her completely, but Twilight was the perfect size for him. He felt ever confident in that moment that what he was doing was right.

"Fuckkk....Twily, you're so fucking tight! You feel incredible sis." Shining moaned. He slowly inched himself back out, making sure to savor every sensation.

Twilight hummed in pleasure before she raised her front hooves and wrap them around Shining's back. She pulled him down with all her might, forcing him back inside. "~Come onnnn big bro. Just take me already.~"

Shining smirked. "As you command, my Princess." Shining raised his hips and slammed into her once again. He soon got into a rhythm of thrusts and moans. As he pistoned in and out he took in every feeling of her warm pussy. He bucked and prodded while his hooves sank into her flanks. "F-fuck. Why did we wait for so long to do this? You're so perfect Twi." Shining moaned louder.

Twilight gently thrusted her body upward to meet his hips. "You feel amazing too big bro. So much better than those dusty old toys. ~I was MADE for you.~" Shining thrusted harder at her words. "Oh, I felt you get even harder...did you like me saying that Shiny? Tell me, am I better than Cadance?"

Shining swore under his breath. She knew exactly how to rile him up. He couldn't lie to her in that moment to save face either. "~Oh heavens.....yesss.~ You just feel...indescribable! Don't tell Cadance...but I love my sister's body more than hers! ~Oohhhhh.~"

Twilight giggled as Shining sped back up. Both ponies looked locked their eyes together. Both their horns started to glow as they stared deeply at each other. Their magic intertwined as Shining thrusted harder, digging into her cunt with all the vigor he could muster. He kissed her cheek and forehead and ran his hooves up and down her flanks as he continued to ravage his beloved sister. Shining could feel himself getting closer and closer. He wanted to last longer, but he knew he had to go all out for his dear Twily. He had to do this right. Shining slowed to a crawl, just barely thrusting in and out. Twilight looked up in confused bliss. "Shiny? Why did you-" She was cut off by Shining grabbing her back hooves with his. He pushed them up and past her head before holding them in place with his magic. Twilight was stunned. He had just positioned her into a mating press! If his intentions weren't clear before, they certainly were now.

Shining slammed into Twilight once more and began to rapidly pick up speed in his thrusts. Twilight shrieked beneath the stoic stallion as he rocketed in and out at a blazing speed! "Twilight! I love you! I love you I love you I love you so much!! I'm going to cum, Twily!"

Twilight wrenched her hooves from his magic and wrapped them around her brother. "Yes! Do it do it do it! Impregnate me! Make me a mother Shiny! Give me a foal! Your foal! I've wanted this for so long! Pleaseeee!"

Shining was at his limit. "I'm cumming Twilyyyy!" With that final declaration Shining hilted home inside her. He slammed with all his might as his cock-tip punctured Twilight's womb and locked into place. Shining felt the dam break as molten hot cum shot from his cock and flooded into Twilight. Both ponies moaned in pleasure as Shining emptied his swollen nuts deep into Twilight's most precious cove. Twilight was paralyzed in bliss. She could only lay there as her brother vigorously impregnated her. She loved every second as his cum flooded her womb and sought out her eggs. Shining could only hump further into his sister as he unloaded what felt like a week's worth of cum. His mind raced to images of her pregnant form and it only made him cum longer. As he slowly started to teeter of Twilight released her death grip on his body, allowing him to thrust with all the power he had left. He used the last of his strength to ensure he had thoroughly impregnated his dear sister Twily. As Shining's strength finally gave out he collapsed onto Twilight, his cock still lodged inside her. He twitched with every little movement of his body, but he didn't care.

Twilight finally came down from her euphoric high and sighed at her brother. "Shining...that was AMAZING!! I never knew I could feel so good. Look at my stomach! You shot so much inside me, I'm sure to be pregnant now. Thank you thank you thank youuu..." she strained out her squeals as she hugged his form to her once more.

Shining soon pulled out and plopped beside her, the flow of cum oozing out of her in a steady stream. "That was...the best sex I've ever had."

"Hey! I heard that mister!" Suddenly the two ponies jumped as a voice came from the doorway. Standing in the opening was Cadance, and she looked annoyed. "How dare you Shining, say something so hurtful in front of me.....hehehaahahah. I'm totally kidding!! Haha!" The pink alicorn slowly approached the bed as the two bewildered siblings still gawked at her. "...What? Oh come on. It was my idea to send you in here. You didn't expect me to NOT come and see the aftermath, did you? So...how you two lovebirds feel?"

Twilight got over the shock and pulled Shining into a kiss on the lips before he could say anything. "O-Oh! I see it went veryyy well." Cadance smirked.

Twilight released him from the kiss and smiled. "Yeahhh....it was magical! I think it worked...I feel like I'm pregnant already." Twilight rubbed her swollen belly with her hooves.

Cadance looked down at her sister-in-law's stomach and chuckled. "Damn, that's really hot. You really did a number on her hun. In fact..." Cadance got into bed with the siblings, sliding in on the other side of the svelte stallion. "You did such a good job, that I want a piece of the action too..."

"Huh!?" Both siblings gawked.

"You heard me hot stuff! You gave Flurry a cousin or two, now how's about we give her some siblings as well." Cadance began to grind her ass against Shining's flacid cock.

Twilight smirked and formed a plan. "That sounds like a great idea Caddy. Come on, let me help you get him in the mood again."

As both alicorns rubbed against Shining he snorted before replying. "You two are gonna be the death of me...and I couldn't think of a sexier way to go out. So what are we waiting for? The night's still young and I heard there's a mare who also wants some action?"

Cadance and Twilight grinned mischievously before they pounced on Shining. As the night drew on the three ponies continued in their little tryst. They didn't stop until late into the morning when Celestia's sun began to rise once more. The three ponies would go on to have many more "bonding" days, until a week later the inevitable was revealed. "We're pregnant!!" That was all Shining heard as the two mares held their pregnancy tests in front of him.

Shining smirked. "Well you DID have me to thank for it... So, don't I deserve a reward?"

The two mares smiled deviously before grabbing him by the hoof and dragging him toward the bedroom once more. "We thought you'd never ask ya stud."

"I could get very used to this...." was all he said as he closed the door behind him, ready for another full day of family bonding...

Author's Note

I might write a chapter showing Cadance's turn in the future. I'm not sure yet.
