Bucked Your Sister You Did
Eventually, they stopped thinking
“Excuse me, mom! I have an announcement to make,” said Sunburst, firmly sitting in the comfy sofa of his humble home, “Excuse the mess here, I just didn't have time to clean up after what I did last night,”
Sunburst had his mother, known as Stellar Flare, over for some lunch at his own home. It was a very long time since she ever left Sire Hollows—3 years to be exact—and her first destination is none other than her lovely little colts house in the Crystal Empire. She was sitting right across from him levitating a cup of freshly made tea with a lemon pinched on the side of the tip.
“What could be getting you all excited for making your home such a pigsty!” she ridiculed her own son's excitement over making a huge mess, “Look, there are books on the ground, scrolls scattered all the place, and your bed frame is a total wreck? What possibly could you have done to be so happy for?”
“Well...let's just say...you'll be getting a grand foal like you always wanted,” Sunbursts gently put up a small grin with his eyes glaring at her.
“Oh my! Did you actually?” gasping shortly after his announcement, she dropped her teacup to the ground causing it to crack and splatter on the floor, “... Did-my-baby-boy-lose-his virginity-to-a-mare!?”
He nodded, brushing his small goatee with his left foreleg. “Yes!”
Like it happened in a flash, she teleported right next to her son on the long sofa and wrapped her forelegs around him for a hug. Squeezing him like a pimple, she squealed like a little filly.
“Oooooh, I'm so proud of you Sunburst! I'm finally going to be a grandmother!”
“Y-Yes, mom! Can you please let me go! I need to tell you something else; the mare I did it wi—”
“—First, tell me how it went! I need to learn how my baby boy did on his first-ever mare!” letting go from her hug, she gave time for him to take deep breaths.
“Are you sure? I don't think I feel comfy telling about how I did --==it to my mom, no offense!” Sunbursts are flustered as he felt a bit of embarrassment over speaking about sex to his mother.
She giggled, “Oh please! It's not like I don't know a thing or two about sex. Just tell me what you two did... In the bed of course!”
“Um, okay,” Gulping as trying to confess to a crime, Sunburst began spilling the beans, “First, after I invited her over to my bedroom when our date ended, she pounced on me and proceeded to make out on my bed. Swirling her tongue around mine and rubbing her groin against me.”
“Oooh! She's one of those freaky mares. My sweet little colt knows how to pick em!”
Sunbursts giggled alongside his mothers' comments, “During our kissing, I gently went over to her stomach and kissed down to her...her... Va… Va...”
“You can say it in front of me, sweetie! You're a full-grown stallion now!” encouraging her son to say some vulgar language, she gently placed a foreleg on his shoulder.
“...her...VAGINA!” he shouted, “And ate the living Tartarus out of it!”
“Oh my! My son taking the first approach...” she giggled back, “So, you know exactly how it tastes, huh?”
“Yeah, it's a bit pungent at first, then she started to squirt all over my mouth. It had a sweet tang to it,” Sunburst could see his mother nodding as he went on, “Then, she went ahead and sucked on my penis,”
“Oh! She was intimidated by your size. I sure I would be if that were up to my haunches!”
“What!? How did you know I was...big?”
“Heh heh...your mother learns a thing or two at her youthful age of 27...” she teased.
Sunbursts laughed along with his mothers' big wink, “Anyways, I managed to splatter my load all over her face, and she still went ahead sucking!”
“Amazing that this mare could be so much into the facial...what else have you done? Does it have to do with your bed frame all busted up?”
“So, while she sucked my dick, I went ahead and licked up her pussy... I was kinda nervous at first.” embarrassed, Sunburst blushed a bit, “I think It's called Position 69?”
Stellar Flare was already riled up in her body, as her son speaks about his very first time in front of her. She couldn't ever be so proud, “AHH yes, the classic position 69. Pleasurable in both the mare and the stallion; A staple in the many different sex positions of Equestrian kind!”
“Ehhehhehh,” he ominously hesitated to answer, “You know all of the sex positions, right mom?”
She tensed up. “Yes, I've embedded it in my head, why?”
“Becuase...we kinda...did-every-sex-position-in-existence!”
With that, Stellar Flare gasped as her jaw dropped a few inches down. Complete stunned and utterly impressed by her son's energetic tone as she imagined what the poor mare's bum feels like in the morning.
“My-My! That mare was gotta be filled with enough semen to give her quintuplets!” Stella Flare was cringing up, “How on Equestria can you last for so long?”
“See, she's a unicorn-like me! She did this spell where my penis stayed up to its maximum size. Even gave me infinite stamina, increase sperm creation, the whole enchilada!” he pridefully screamed over her head, crazed with eccentric energy, “I felt like a total machine plowing her minute after minute! Cum guzzling down her holes! Hearing her scream OHHHH! Buck me Sunburst. I've been waiting for this moment all my life! Ever since you got your cutie mark is when I wanted to rut you!”
Like a record player broke in her head, Stellar Flare could tell who was he mentioning after she gasped, “S-Sunburst, slow down! You said she screamed since when we were foals. Could you perhaps had sex with... Starlight Glimmer?!”
“Sorry about that...and yeah, Starlight was the one who I gave my precious seed to.” he panted gently, adjusting his reading glasses to ease himself, “I thought you knew that? Who else would want a piece of me? Nopony but Starlight...”
“Oh...OH MY!”
“Huh?”
Stellar Flare soon fainted almost the sofa, leaving him scratching his head onto his mother's strange behavior.
15 minutes ago
“Oh my, sugar plum! This castle is through the roof!” Firelight ecstatically said trotting in the main hallway of Twilight's castle, “Still, though, I prefer to preserve the original look of this wonderful castle to keep its rightful look.”
“The castle was magically made by some tree! How the hay is we supposed to preserve its original look!” yammered Starlight, completely irritated by her father's logic.
It was Firelight's first time leaving Sire Hollows and tour Ponyville in many years. Starlight had been giving him a tour of places he could remember (and criticize over how it changed). Nonetheless, it was the same old father stuff she had to stick with the rest of her life. Soon after the reached the map room, Twilight was just trotting along their pathway, greeting them with a smile.
“Oh, you must be Starlight's father, I'm Twilight Sparkle the—”
“Princess of Friendship! Of course, I know you. From Starlight's letters written about you?” he greeted the princess by giving her an informal hoof shake, “Let me be the first to say, That I'm honored that my precious sugar plum is going to be taking over your school of friendship soon. Second, We must be discussing how we could preserve the school's structural design to keep it as its original look for many generations.”
“Well, it was just built a few years ago...so I guess it'll stay the same for pretty long,” she hesitantly replied, “So anyways Starlight, I want to discuss to you about...his size”
“His size? What are you two talking about?” Firelight anxiously turned his head.
“Oh no...” she muttered, completed hesitant to tell her father the truth,
“Dad... I'm an adult now, and as an adult, I should be able to make decisions for myself! I've decided to get a colt friend”!”
“That's right sugar plum, you are allowed to get a colt friend as you wish! Just tell me more about this strange pony you came acros….” he glared deeply down to her.
“Last night was a wild ride with your daughter if you get the gist” Twilight snickered next to Starlight, trying to cover up her mouth with her forelegs wrestling against her magic.
“Wild ride?” Firelight scratched his chin.
“Let me put it this way; After they ate dinner...things got a little heated when he walked her over towards her house, then started to ram her on his mattress like there's no tomorrow Mr. Firelight”
“Dear Celestia!”
“Uh oh...” Starlight gulped amidst her father preparing to give her the talk of her life seeing the fire in his pupils.
“Ms. Starlight Glimmer! You're telling me you had sex with some stallion who tried to take advantage of you!?” Firelight for the first time acted like the overprotective father he wished to be.
“Well, you're on your girl!” Twilight lit her horn up and disappeared in front of them.
“Fucking Twilight...” Starlight clenched her teeth together.
Her dad intimidated her with another question, “Did you even use protection at least? Huh?”
“N-N-Nooooo...” she stretched her answer in a long drone.
“I can't believe that my little pumpkin-wumpkin acted like a whorse and was okay to get bucked by some stallion of her choice! I am completely disappointed with you to miss!”
“Come on dad! I've just been waiting SOO much time for us to finally be a thing—”
“—Enough young lady!” Firelight cut her off, “I'm grounding you for not only for keeping this a secret but for getting yourself pregnant! Who is this delinquent stallion so that I could teach him a lesson for trying my daughter!”
“He isn't a delinquent Dad... It's Sunburst of all ponies!” she answered, “Albeit, he was a complete monster in bed, but I kinda like it rough—”
His eyes shot up, pausing his rambling when he heard Sunburst's name. “No...”
“No?”
“S-Starlight...where is Stellar Flare right now?” he calmly asked, with a blank expression running down his face.
“Well, she should be with Sunburst at his house at the Crystal Empire,” answered Starlight.
“Take us there!”
“But, what about the—”
“—Just take us there!”
An hour later, Starlight came crashing in the doors to Sunbursts' house, a bit worried about his father's motif of intervening with his time with his mother. Stellar was just about up and running from her sudden faint a few minutes ago, still with a pounding sensation on her head. Before Starlight could speak up, she tried to give Sunbursts a quick kiss on the lips. However, her father sort of interrupted her by levitating her body with his magic.
“Ack! Dad! What the hay are you doing? I'm trying to kiss my colt friend!” she urged to make contact with her beloved.
“N-N-No! Not now and never!” Firelight's dad instincts rolled by, “You aren't seeing Sunburst anymore!”
Sunburst was dismayed on his stance staying silent in this; What did he ever do to make him so upset? Besides his daughter!
“Huh?! Why not?! I've been wanting to be with him ever since we were foals!”
He came from behind her and pushed her away from Sunburst by a few feet, “I said NO! Stellar Flare...what kinds of sexual acts had Sunburst did to my poor Starlight?”
“Yes...” she answered briskly.
“Yes? What does that even me—”
“—He did ALL of them!”
Firelight soon dropped the magic from the hold of his daughter, looking very nauseous as his cheeks went green. He was about to hurl, but luckily he summoned a trash can and managed to barf inside it. Took him a few seconds to come back to the whole situation.
“No...this shouldn't be happening Stellar, It SHOULDN'T BE!”
“What? What's going on with you two?” Sunburst tried to take hold of the situation, “Mom, what's going on? Why can't I see Starlight anymore? I mean, she IS pregnant with our child!”
“Oh my... I shouldn't keep this secret to you for this long,” she was on the verge of tearing up, about to hurl as well, “Alright Firelight...let's come clean...”
He nodded, “Yes, It's for the best...”
“Wait! Can anypony tell me what's the hay is happening right now?” Starlight firmly tried to figure out what keeps their parents so disgusted, “So what I handled loads of cum? I can take it a—”
“Come sit sweetie, both of you!” cried her father, “You need to hear this...”
She followed and teleported over to the sofa while Sunburst trotted over there. Sitting very close by together, their parents levitated them on the edges of the couch.
“First's things firsts...we are going to explain this to you in the most sensible way. All of this will make sense as soon as we finished talking.” she briefly went over, and they both nodded. “Now, Firelight...take it away!”
“It all started just before both of you were born...” Firelight carefully sat down on the single love seat, revealing everything, “Me and your mother Starbright just got hitched and moved the Sire Hallows. Luck hits, and we were neighbors to Stellar Flare and Sunspot. After exchanging names and conversations, we all became fast friends. That is until we wanted to have a foal of our own...”
“And that foal would be me!” Starlight abruptly finished his story, bored to her mind, “How does the—”
“—No... Unfortunately, Starbright could not have any babies for herself. She wasn't fertile enough is what the doctor mentioned before,”
“Huh?” Starlight's eyes were completely distraught, hearing the utter truth of her birth, “Then, how did I—”
“That's where I came in...” Stellar continued his explanation with her voice, “Well, I and Sunspot recently heard their sad news, and I could not believe our neighbors couldn't bare a foal for themselves. At the time, spells to induce a pregnancy didn't exist—and even then, it would be illegal. After many long weeks discussing and negotiating...we all came to a compromise,”
“A compromise?” Sunbursts cringed upon the topic.
“You see, we have come to this agreement...” as Firelight was about to finish, he could feel his stomach in a twisted pretzel,
“... Th-That I bucked Stellar Flare so that she can hold our foal in her womb.”
“Uhhhhhh...what!?”
“I knew you would act all like this!” Stellar covered her face over towards her son, “Yes Starlight, you are also a foal that I carried with you! You are my daughter!”
“B-B-But, that doesn't make sense!” Sunbursts rejected the cruel reality that Stellar shot him with, “We're the same age! You would have to have a threesome with Sunspot and...OH-MY-CELESTIA!”
“Y-Yes sweetheart... Just as you are imagining; I had sex with TWO stallions! AT...THE...SAME...TIME!”
“We inserted our seeds into your mother's fertile factory!” Firelight couldn't even look at him as he averted all eyes, “We would then wait the whole nine months until she gave birth. Then, she just handed us off the one that had my eyes. In short; you two are brother and sister...”
“...” Sunburst stopped thinking.
“...” Starlight stopped thinking.
“I know it's hard to take in, just please understand it was for the greater go—”
“AHHHHHHHHHH!”
Shivering immensely, Starlight crawled into a fetal position, rocking back and forth among the couch. As for Sunburst, he was running frantically all over his house, screaming out of his lungs over their bear-bone explanation.
“MOM! You're telling me that the ONLY mare that would ever want to buck me ever since foal hood, is also my sister?!” he verbally cried out.
“Yes, sweetie...”
“D-D-D-Dad! P-P-Please tell I did not just have sex with my brother?” pleaded Starlight, stammering off alongside a hint of green alongside her cheeks.
“I'm afraid so, darling...”
Starlight quickly lifted the trashcan from the ground and vomited inside. She completely lost contact with the outside world, twitchy body and eyelids left her like a half-dead fly who had just been swatted.
“N-NO! It's not true...THAT'S IMPOSSIBLE!” Sunbursts lifted himself from the pole lamp just behind the sofa, avoiding the fallout of that truth bomb that just dropped, “Mom! Are you pulling a prank on me again!?”
She shook her head, “No dear, Starlight is your twin sister... I just never thought you two would actually...go through with this.”
“B-B-But... I masturbated to her!”
“Correction, you masturbated to your sister,” finished Stellar.
He dropped to the ground, crying in agony over the sudden realization that he jerked off every night for so many years to his sister, “NOOOOOOOOOOOO! NOOOOOO!”
Later in the Crystal Palace...
“You two are brother and sister?” Shining Armor couldn't believe what Sunburst told him, “And your mom had sex with two stallions to do so?!”
“Y-Yesss...” Sunbursts squealed in total embarrassment, shaking vigorously next to the Prince, “I can't believe that the mare of my entire dreams...is ALSO my sister!”
“Damn, Sunburst!” Shining Armor right next to him pampered the poor fellow by stroking the back of his neck, “I can't believe your mom kept this secret from you for ages! Where's Starlight? Is she okay?”
“Starlight's currently puking in the washroom right now with Cadence,” Sunburst answered him right away, “She even tried to go to the hidden archives and grab a time-traveling scroll to change the past. But that doesn't matter, I just BUCKED MY OWN SISTER MAN!”
Shining, strangely enough, chuckled hysterically with sweat beads running down his forehead, “Oh, you poor-poor thing...you bucked your sister...who would ever do such dastardly deed!? I know I won't...”
Onto Starlight, who locked herself up in one of the restrooms in the palace with a very worried looking Cadence knocking on the doors with her right foreleg. The door has been shut for nearly 10 minutes, as she could hear faint gagging and puking sounds echoing outside the room.
“Starlight dear! It's alright that you had sex with your secretive twin brother!” she yelled loud in front of the door, “Incest is the most precious type of love out there! It links two loving souls together only getting weighed down by their sibling relati—”
“NOT...HELPING!” her voice crept through the door.
Their, Cadence could see Twilight flying over next to her sister-in-law. As she went ahead and figure out what was the commotion inside the room.
“That sounds like Starlight in there, is she alright?”
“It's just that, she had sex with Sunburst who was her long-lost brother. The secret was kept by her parents, and they just figured it out today...”
“Pfft, so what your brother nailed you Starlight? Didn't stop me in the past...”
Cadence's eyes bulged up in fury, “You WHAT!?”
