Like Two Peas in a Pod
By Flutterwhy4
This isn’t the most flattering story of my life, you might even call it a confession, but I’ve kept it inside for too long. My name is Shining Armor; you may know me as the captain of the Royal Guard. I’m quite proud of where I am today and for everything I’ve accomplished, but this isn’t about that. What I’m here to tell you of, happened some time ago, when I was just a colt.
~ ~ ~ ~ ~
I grew up in Canterlot with my mom and dad and my younger sister, Twilight. It’s a unique city for sure, and I don’t just mean because of the castle and the amazing architecture and history. Being a young unicorn in such a high-class city was nice, I’m not complaining, but it was also a bit stressful.
My sister and I lived in a wonderful home in a great neighborhood. We had access to private schools and the best teachers in Equestria. All the opportunities that less fortunate ponies lacked were given to us, but that also meant more was expected from us.
I was just your average colt. I liked to play sports and hang out with friends. I never considered myself the smartest or most talented kid on the block; truth be told, that honor would have to go to my sister.
From the moment she was born, I could tell Twilight was special and as we grew up together she proved it. My baby sister was a gifted little thing with a penchant for reading. I swear she would have her head in a book nine out of ten times I saw her. I suppose that was a good thing, but it did make me worry sometimes that she wasn’t socializing enough.
Mom and dad knew Twi was gifted too and they definitely encouraged her from a young age. You’d think it would be hard living in the shadow of your little sister, but I never saw it that way. She pushed me to be all that I could be and I’ve always loved her.
More than anything, I just wanted to be the best big brother I could be: the kind of big brother who’d be there for her, who’d be a friend, who’d help his sis with her homework, though with Twi it was often the other way around. I always felt like I accomplished those goals.
Living at home, our parents gave Twiley and I a lot of independence. They were certainly there to encourage us, but they left our school, athletic and social life up to us to manage. Of course, since my sister was so young, I had to play a role in her school life. Dad often told me that foals should be free to learn from their own mistakes. He and mom trusted us, and knew that my sister and I were close and would always be there for each other. Little did they know how close we were about to become.
~ ~ ~ ~ ~
I was in my room one night as I often am. My room is fairly simple and ordinary: a plain, blue bed; a desk with a light, some trophies on hoof-made shelving and ribbons hung proudly on the wall; no big deal. While Twilight was the smarter sibling, sports was more my thing. I loved the thrill, the community, and the opportunity to be a leader, and as the star player of my school’s hoofball team I had my fair share of friends and fame too.
Of course, part of being that star everypony loves is keeping in shape. Cool sweat dripped from my mane as I sat on the edge of my bed pumping a large barbell into the air. This was something I’d try to do at least once a day, sometimes more if a big game was coming up.
I’d learned that the best fitness plan was to pick the same time every day and stick to it. I chose the hour right after dinner and the whole family knew that was my time, that’s why I wasn’t expecting Twilight to come barging into my room, but she did.
The door opened and my sister strolled in with no regards for privacy. I might have been mad if I didn’t love her so much, but I brushed it off and made a mental note to have a talk with her about knocking. She is just a filly afterall, I thought.
“What’s up Twiley?” I asked. I had noticed her acting strange for the past couple of days. She seemed, quieter, more reserved than usual, quicker to leave the dinner table and keeping her door closed more often. It didn’t seem like too big a deal, but as her big brother I was planning on bringing it up to her, I just hadn’t had the chance.
She closed the door behind her and turned to look at me. Her normally bright, wide eyes stayed fixed on the floor and red cheeks framed a sullen pout on her muzzle. Upon seeing her, I stopped what I was doing and set the weight on the floor next to my bed.
“Brother, I need your help,” said Twilight, her voice laced with almost a defeated tone.
“Sure, what’s eating you, sis?” I left my bed and trotted over to her.
“My... my kitty is itchy.” Her voice came out like a hushed squeak.
“What?” The statement left me confused. Twi looked up. A glance over her withers and a swish of her tail told me of what she was referring. “Oh. Oh!” An awkward acknowledgement was all I could give her.
Luckily, she came prepared. Twi began to explain to me that earlier in the week she had been playing with her Smarty Pants doll when she ‘rubbed herself funny’, as she called it. She went on to confess that she’s been doing it on purpose ever since. The way she described things was that of an innocent filly, unsure of what she was doing; if it wasn’t so personal, it might have been cute. I listened out of courtesy as my sister unwittingly told me of her first experience with masturbation.
“It makes me wanna pee, but then I go to the bathroom an’ I don’t hafta.” Twi said, opening up as if describing some mundane frustration.
I know I’d promised to always be there for my little sis, but I couldn’t help her with this, could I? It was oddly touching that she would come to me. I poured over my options. Maybe I should at least explain what she’s doing? Then again, it might be pretty awkward to have the birds and bees talk with my own sister. My brotherly heart finally conceded to my wisdom. As much as I hated to admit, Twilight had finally found something that I couldn’t assist her with.
“I think you should talk to mom about this, Twiley,” I scolded gently and gave her a little noogie. I hoped that would be the end of it, but she persisted. Twilight grabbed my hoof and batted her big, teary eyes at me.
“Oh pleeease! I can’t concentrate on my reading an’ it’s driving me crazy!” Twi shouted. I’d never seen her so worked up.
“Uhhh... Twi, I can’t.”
“Will you just look?” The young, purple unicorn turned away and buckled her forehooves, raising her tail and presenting her filly rump to me. My jaw went slack as I found myself staring at my sister’s privates.
This wasn’t the first time I’d seen Twi this way; we’d grown up together, even shared the same bathtub when we were younger, but this was different. Not only was her posture submissively sexual, her soft lips were spread and plump and her backside was matted with the stickiness of a filly fumbling to bring herself off.
“Brother?” Twi asked, looking back at me without breaking her pose. “See anything?”
I’m not sure what came over me in that moment. My sis seemed so confused, I guess I couldn’t stand to not help her, the way only I knew how. Consequences failed to enter my mind, I was Twilight’s big brother and I would be there for her.
“Fine. I can help you, but you can’t tell anyone, okay?” She stood up and puzzled at my change of tone. I was second-guessing everything I was about to do, but protest never registered inside me. I climbed onto my cool bed and sat down on my tail in the middle of the mattress. “Here Twiley, come over to me.”
My sister came over and crawled up onto the bed, unsure of what I was planning. I motioned for her to sit like me, patting the open space between my hindlegs. She didn’t hesitate before plopping down in my lap.
I grabbed Twilight by the waist and scooted her back against me. We were now together, my belly against her warm back. I twisted and reached behind me for the airy, white pillow which I used to keep myself propped up.
“What are we doing?” Twilight asked. Keeping her in a comfy embrace with my left hoof, the other found its way into her lap where I spread her young legs and made them flush with mine.
“I’m teaching you how to fix your little problem,” I told her, “now relax, sis.”
Part of me wanted to dive right in and get this lesson over with, but aware of what I was doing, I knew I should make it memorable; it would be her first time after all. I began to stroke her purple belly up and down, rhythmically. My other hoof climbed Twilight’s smooth thigh and passed inches over her genitals, rubbing down the other one.
“It’s not getting better,” Twi said.
“Shhh… I’ve barely started, sheesh.” If this filly wanted her orgasm so bad, I’d happily oblige her. My thick hoof worked its way back to start its most important work. Twilight jumped against me as I found her virgin flower. I pressed into the soft flesh, feeling her intimately for the first time in my life.
I slid down my sister’s delicate slit. Two skinny legs gripped and quivered against the foreign hoof. A soft whimper encouraged me to continue.
Being a star athlete at school meant that I was not unskilled when it came to mares. I was anything but a womanchaser, the way some of my teammates were, but when a cute girl hits on you it can be hard to say no; I’m only a colt.
Looking over my sister’s head I could see everything. Twilight was slumped against me, spread open, her cute body like putty in my hooves. More surprising was how wet she was. I didn’t think a filly her age could get like this, yet her swollen mound shined with the sticky reflection of my ceiling lamp.
I removed my hoof from its humid prison and had Twi spread her legs wide again. Her feminine playground unobstructed, I went back to helping her. A quick tap on her clit caused her back to arch and a mew escape her otherwise silent mouth. Another tap produced similar results.
“See this, Twiley?” A flimsy strand of my sister’s warm juice made the perfect path for her eyes to follow from my hoof to her nubile pleasure button. “That’s your clitoris. Now I’m gonna show you how to make those feelings go away, and whenever you get them again, you can do this yourself.” The purple filly nodded.
I felt compelled by some force to kiss the back of Twilight’s head before continuing. Her mane engulfed my muzzle as my lips found purchase. My hoof sunk firmly into the top of her pussy, a squishy nub buzzing against me. Twilight squeaked. I rubbed her slowly from side to side, my brotherly touch sending electricity up her spine.
Even though deep down I probably knew this was wrong, my mind wouldn’t tell me. All I could focus on was how much I loved my special sister and how delighted it made me feel to be able to give her this pleasure. She came to me with an embarrassing problem, she trusted me and I’d be damned if I was going to turn her away without giving her my all.
Twilight’s breathing became shallower as I spun my hoof in pleasing circles around her inexperienced clit. I held her in loving embrace as I diddled between her legs, her warm, little body becoming slick against mine from sweat. My sister’s happy tail swiped across my thigh as we sat together enjoying the moment.
My own loins began to stir as I rubbed. Even though this was about Twi, the heat and the stimulation was more than my body could ignore. I lit my horn and shifted my growing penis away from my sister as best I could. I was sure she’d be able to feel something, as tightly pressed together as we were, but hopefully I could keep my full thickening length off her innocent back. She probably wouldn’t know what it was anyway.
I sped my ministrations up and Twilight responded in kind with louder mewing and full-body twitches. My hoof was now soaked in my sister’s fluid. I pressed harder on the hot ember under my touch and she let out a sound somewhere between a choke and a whine.
The room had smelled of masculine sweat from my interrupted workout, but now the musk was cut by the sweet, pleasing scent of my younger sibling. Her flowery juices were an air freshener I would never complain about.
“B-brother I… een... I feel… fuh-n-ny.” Twi tried to speak between shallow addled breaths.
“That’s good, we’re almost there. You’re doing great,” I said. My muzzle wrapped around her head and took a tiny ear between my teeth. I growled and bit gently, my eager hoof still freeing sweet nectar from my sister’s honeypot. “Get ready sis,” I warned her.
I went into overdrive, kneading the swollen pussy beneath me and begging it to give my sister the release she needed. I was seconds away from one of the most satisfying moments of my young life. I fondled my sister’s petals with love. Her body clung to mine; her breaths became ragged. I stroked harder still.
“Nng, brother I… I… I-ooooo…” Twilight moaned and fidgeted in the throes of her very first orgasm, an orgasm I had given her. I nibbled her dainty ear as she bucked and came against me, my heavy hooves wrapped around and pressed against her tight. The air thickened from a fresh injection of her girly scent.
Almost a minute passed before my Twiley had finished having her special moment. I fell backwards onto the bed, taking her with me. We lay there together, a pile of spent filly and her brother. I stroked her soft mane in silence, as her young mind struggled to register the incredible sensation she’d just been racked by. As she recovered, it gave my own embarrassment time to return to its resting place.
“Feel better, Twiley?” I asked.
“Yeah. That was amazing,” she replied weakly.
“Alright then. We should probably get you cleaned up and then it’s off to bed.” I excused myself from our sweaty embrace as if nothing had happened and left Twilight to draw her a warm bath. When I returned to my room she had gotten down from the bed on her own. My sister came up to me and gave me a hug ten-times her size. Her flushed face was beaming with joy as I smiled down on her.
I walked my little sis to the bathroom and helped her into the tub. She’s old enough to take her own baths, but sometimes it’s still fun to treat her like a baby. Usually she would get huffy, but not this night. I reminded her to wash behind her ears, then, knowing she would be okay without me, I turned to leave.
“I love you big bro, you’re the best!” She hollered from the tub.
“I love you too, Twiley,” I said with an earnest giggle.
Back in my own room, I closed the door and trotted over to my bed. The sheets were stained with a huge puddle of my sister’s cum and sweat. I bent my head to smell it; it was even more pungent up close, but arousing. I would have to wash my blankets in the morning, but tonight I needed to masturbate and so I did, using the same hoof, still sticky from before. The thoughts of what just happened danced in my head all while I stroked myself. I came harder than I’d ever cum before and as I lie there in post-orgasmic trance, I tried to convince myself it would never happen again, that I’d taught her all she needed to know, but part of me didn’t want it to be true.
I had a hard time getting to sleep that night. My head spun with thoughts, regrets, worries, desires and more. I couldn’t get the evening’s events off my mind. Eventually tiredness won out over contemplation and I drifted off to sleep in my cold, wet bed.
~ ~ ~ ~ ~
I told myself I wouldn’t have any more sexual contact with my little sis, but I did. You can blame her for needling me and guilting me with those cute purple eyes, but in the end, it was I who couldn’t say no. Like her personal servant, whenever Twilight needed or wanted relief she would come to me.
We did it everywhere: my bedroom, her bedroom, the bathroom. I was especially fond of Twi’s bedroom, the frilly bedspread and jaunty, innocent décor made the act seem all the more taboo. I never went farther than touching her, but the exuberant smile at the end of each session was reward enough for me to keep her pleased when she wanted it.
My sister even started to get more brazen with each passing day. One night we were eating dinner with our parents. I dipped a spoon into my soup and took a sip. Mother’s cooking is delicious, I thought. Twi was seated next to me, levitating globs of the tasty broth into her mouth with playful giggles. Mom scolded her for playing with her food. I went to take another mouthful when I felt a light kick from under the table. I looked over and saw my sister spreading for me in her seat! It was as if she was testing me, seeing how far I’d be willing to go.
~ ~ ~ ~ ~
“Nng… Nng… Nnnng! Eek! Eeeep!” Twi came as I massaged her sticky crevice. In her room, I held her rising and falling chest, just as I had done our very first time. The perfect moment, lying there with my lovely sister panting in post-sex glow. It was so peaceful. I wanted to curl up around her and fall asleep right there, but I knew it was too risky. Maybe if we were in my room we could tell mom that Twi had a nightmare and came to sleep with me, but not here, and not with the smells of incestuous love in the air.
“B-brother, can I tell you something?” asked my sister, still high from the work of my skilled hooves.
“Of course you can.”
“You gotta promise not to get mad.” I perked up and looked her in the eye, she was clearly serious. I nodded. “I know what we’ve been doing,” she said softly.
“You what??”
“You promised you wouldn’t get mad!!” My sister shouted.
“I’m not mad! I just… so you knew this whole time??” I asked. All the concerns I should have had from the start came brimming to my conscious mind.
“Naw, when you did it the firs’ time I had to read about what that feeling was.” I wanted to ask where a little pony like her got a book about reproduction, but I knew that if anyone had the resources to find a book it was Twilight.
“And you let me keep doing it? You naughty filly!” I scolded. I really wasn’t mad at her, just a bit shocked to learn my sister had used me like this. Overall, her knowledge hadn’t changed a thing; I wanted to give her the pleasure I did and she wanted it too.
“Why’s it naughty?” my sister asked, naïve.
“Because. Brothers and sisters aren’t supposed to do that with each other.”
“But why?” she pressed on.
“I dunno, it’s just, like, a rule, I guess,” I replied, a bit embarrassed. This was almost like being caught cheating on a test.
“Hmmmm… seems like a silly rule ta me,” Twilight said. I didn’t reply. I just sat there on her bed, contemplating the past couple weeks. Was I a terrible brother for doing what I did?
The clock ticked by for what seemed like minutes. Twi shifted on the bed in front of me. I looked down at her. She smiled back with a glazed look of happiness, like a dog waiting for a ball to be thrown.
“So can I do you?” She broke the silence.
“What??”
“Can I do you, like you did me?” I couldn’t believe what I was hearing. My sister wanted to touch me. Accepting her request seemed like it would cross a line I didn’t want to venture past. I was already having reservations about what I’d done to her, now that she knows; letting my little sis fondle me was another thing entirely.
“I don’t know Twiley, I shouldn’t have touched you like that to begin with. You’re my sister, we’re not supposed to.” I hoped she wouldn’t be too upset.
“But you did it to me! I should get to do it back!” Her voice had a hint of tantrum.
“Yes, but that was because I love you, and I wanted so much to help you.”
“And I don’t love my big brother?” She had me trapped. I relaxed into her pillow and tried to think. Twilight interpreted my lack of response and lowered her little hoof onto my sheath. I gasped from the shock, but couldn’t bring myself to stop her. Damn it, I wanted this just as much.
Twiley plopped down onto the mattress with her hooves on either side of my groin, watching my cock protrude like a cat following a goldfish. I wasn’t the thickest colt, from what I’d been told, but what I lacked in girth I made up for in length.
I stared in embarrassment as my sibling marveled over my hardened instrument, her face mere inches above the speckled meat. I half expected her to dive right in, but she inspected every inch of me and batted my cock one way and then the other, studying it.
“Wow… so big. That’s supposed to go inside me?” My cheeks turned to fire at my sister’s suggestion, but rather than say anything I merely gulped.
The heavy rod rolled across my belly as the filly played with it. Having my own sister handling me was a thrill to be sure, but her inexperienced and calculated touch wasn’t going to get the job done. Still, she was a joy to watch. Her cute scrunched face, tongue out in concentration as she explored her first colt, making mental notes of all the textures and smells she could.
It was clear that I was an unfamiliar puzzle for my gifted sister. Her lack of talent in this regard was a blessing in my eyes. It meant she was still pure, innocent, and it meant that I would get to be her teacher, an idea that made my cock flex. I heaved a sigh to get my Twiley’s attention.
“If we’re gonna do this, I’m gonna teach you to do it right,” I said.
“Oh yes! Please! Teach me brother!!”
“Alright, settle down. You know what everything is from your book, right?” I asked.
“Yes! This is the scrotum, an’ this here’s the medial ridge, an’ th-” I stopped her with my hoof against her lips.
“Twiley. It’s a cock, not a flying machine. Just call it a cock… and these are my balls, okay?” I pointed to the appropriate areas. My sister nodded like a good student. “Now you’re going to make some stallion very happy one day and I want you to know how to show him your deepest love.”
Twilight sat back to listen and watch as I slid a hoof under my sturdy erection and propped it up. In seconds I was masturbating slowly in front of my sis. I began stroking the cock between my two hooves, just the way I liked to do when I was alone. Up and down I went, the thin skin shifting across the firm meat within.
Without needing to be coaxed, a second pair of hooves joined mine and took over as I laid back and enjoyed myself. Twilight jerked my hot flesh with metronomic precision, tugging my testes with each upstroke. I shivered at my sister’s touch; I would need to teach her to be less mechanical and more passionate, but for now her supple hooves made a cozy home for my colthood.
I moaned as my cock throbbed for the attention. My eyes opened and I saw Twilight watching my face expectantly as she worked my shaft. I imagined what it must be like to be her, having never seen someone in this state of ecstacy; the thought alone was almost enough to set me off. I wanted so much to cum for my sister, to give her a new datapoint in her sexual study.
“Does it feel good, brother?” she asked. I nodded sheepishly and made a breathy noise like ‘uh-huh’.
I glanced down at the action. I saw my member, rock hard against tiny purple appendages working affectionately to bring me towards rapture. Precum bubbled on the head and overflowed making slimy trails down my impressive shaft and coating my sister’s hooves.
By now Twilight had loosened up and was getting into the act far more than I gave her credit for. She’d begun to experiment with different techniques and speeds, each one just as amazing as the last. I never wanted the moment to end. I was the most content colt in Equestria. I could have said nothing and been on my way to an orgasm in minutes, but there was still one more thing I wanted to try with her.
“Um, Twiley? C-could you maybe, um, try… licking it?” I managed to find the words I wanted, hoping to not scare her off.
“Lick it? Eewww, but it’s got goo on it!” she complained, still stroking.
“It won’t hurt you, you might even like it!” My sister gave me a sour look. “You won’t know ‘til you try it.” I grinned.
At my request, Twilight bent down and tasted my sticky penis. Her snout wrinkled, but to my surprise and joy she gave me another lick, this one longer than the first. She struggled to keep her hooves and mouth in sync, but it didn’t matter; the scene between my legs was more than enough fuel for my mental fire.
“Iss kinda tangy,” my little sister said between licks.
“Do you like it?”
“I think so,” Twilight responded.
The little mouth moved to the flaring head of my cock where she sipped from the spring of clear liquid. I could tell I was close now; that familiar feeling was welling up in my groin. I laid my head back and prepared for the release.
That’s when I felt the heat and wetness of Twilight’s young mouth wrapping around my head. The shock rippled through my body and the spring inside me unleashed its pent up energy. I writhed in intense pleasure as I gave my sister a mouthful of my essence.
My eyes closed as I enjoyed every mind-blowing sensation. I knew my first spurt went into Twi’s mouth, but after that I lost perception as sweet orgasm overtook me. Nothing I could do on my own would ever compare. I felt as if I’d been teleported to a dimension of pure bliss. My jaw fell open as the cadence of my ejaculations slowed.
“Penis milk?” I heard as I began to come down from the endorphin high. I opened my eyes to see my sister playing with my seed, thick ropes of it hanging cutely from her horn and muzzle. She’d obviously released me from her mouth as I came. The bed and my legs were drenched with warm puddles of white semen. I laid back and watched the purple filly magically inspect and examine my fresh spooge, even at one point going so far as to see if she could blow bubbles with it.
“That’s called cum Twi. It means you did a great job!” I told her.
“Really! Did I really!” she responded enthusiastically.
“Really, sis. I love you.” I invited her on top of me for a hug which she gladly accepted. My dear sweet sister’s tiny body on my chest, I held her tight against me and looked into her eyes, just like real lovers would.
“So are you my coltfriend now?” Twi asked.
I was beset by mixed feelings. Part of me wanted to laugh at the juvenile idea. My sister and I, coltfriend and fillyfriend. Still, part of me was beginning to see her as more of a sexual being. After all this time fooling around with her and after experiencing the heights to which she could bring me, I couldn’t say it was innocent anymore. I loved my Twiley. Maybe it was fated to end someday, but for now I wasn’t willing to stop and I don’t think she was either. We were addicted to each other now.
“We’ll see, Twilight,” I said as I stroked her back.
~ ~ ~ ~ ~
The next couple days proved to be some of the longest in my entire life. Between late-night hoofball practice and Twilight’s study sessions, the two of us saw next to none of each other. Worse yet, I found myself incredibly horny and had her on my mind constantly. I think my teammates could tell something was up; luckily for me they’d never guess what.
On the second night, I climbed into my bed and began to masturbate under the covers. I thought of checking on Twilight, but figured she was probably asleep; mom had put her to bed an hour ago. I felt kind of guilty, relieving myself without her. I wondered if she had had similar ideas.
My door opened and light poured into the dark room. The size of the shadow cast made it easy to tell who was entering, it was Twilight. The door closed and my bed shifted as the little scamp hopped up and squeezed in next to me.
“Pssst! Brother, are you asleep?” Twi whispered.
“No, kiddo. What’s up?” I asked, already having a clue what might be on her mind.
I saw my sister shift, but couldn’t tell in the dark what she had done so I lit my horn, revealing her. She was on her side, one hindleg in the air, exposing her belly and wet undercarriage to me. Her petals glistened in the glow of my magic and the matted coat told me she’d been busy in the last hour.
“Ooh, I think I can help with that!” I slipped the covers off my body, revealing my hard cock. Twi giggled.
“You couldn’t sleep either!” she teased. I copied her chuckle.
I lovingly took my sister’s tail in my mouth and dragged her along the bedspread, getting a stunning view of her as I did. When I had her positioned just right, on her back on the edge of the bed, head almost draped off the side, I got down between her thighs and looked her over.
As it turned out, savoring my treat proved impossible. I opened my mouth and ran my flat tongue across her slit from bottom to top. Twilight moaned and shook a little as I crossed her clit. I took another lick. My head was swimming in the intoxicating floral scent and the sweet taste of her feminine elixir.
My hoof found her thigh and pressed down, allowing me deeper access. I prodded into her fleshy hole and lapped up what I could from inside. The heat was like an inferno, but I pressed on, wanting to graze at her oasis forever.
My tongue withdrew as if on its own accord and began lashing at her swollen clitoris. Twilight turned her head and stifled a squeak into the blankets beside her. I looked up with half-lidded eyes and watched my lovely sister spasming, and craving my tongue. The warmth on my lips was like an old friend’s embrace.
As I buried my face in her loins, Twilight murred and whimpered into the soft fabric clenched between her teeth and against her snout. I circled her throbbing button and made her pleasure increase with each passing second. She was close; I could tell from her rapidly moving chest.
I gave her all I had, my brotherly mouth clamped around her filly bits, lapping away at her like a thirsty cat. Twilight let out a few more squeals and cried into the blankets as she came.
Hot spurts of watery fillycum hit my tongue as I drank deeply of my sister. I could only imagine her pleasure. She convulsed and rode the orgasm as long as she could, my maw on her the entire time.
I swallowed all that I could until she finally slowed her tremors and came back to Equestria. Her head was tilted back so all I could see was her chin, but I could tell she had had the most amazing time. Still, I knew her night was only going to improve from here.
“Soooooooo, awesome!” the filly said before she coughed from lack of breath.
“I’m glad you had fun. I did too,” I said softly, lifting my wet muzzle from her body and giving her one final tender lick in the process.
“It was better than fun!” she exclaimed, leaning forward to speak with me. I gave her a signal to keep her voice down. Our parents were downstairs, but I wasn’t about to risk anything.
“Sorry.”
“It’s okay, Twiley.”
“Hey! Can I do you now?” Twi asked, moving in the direction of my still-hard cock.
“Actually sis, I had a better idea.” I winked. She gave me a confused stare.
I rolled over onto my back and motioned for the young pony to join me. Her face lit up as she began to understand what I had planned. Tonight would be the night I would make love to my sister.
“Really, bro?? Really? Can we?” she tried to whisper, but it came out louder than I would have liked.
“Yes, really! I want you, Twiley.”
She climbed onto me with the biggest smile I think I’d ever seen from her. Her tail mingled with my cock, making it jump and trapping some of her soft hairs between it and my belly.
As I looked into Twi’s shining eyes, I knew what we were doing was okay. What society would think was irrelevant. I pulled her in close and kissed her on the mouth. Despite all we’d done together, she seemed shocked, but she soon melted into my lips.
I opened my mouth and hers opened as well. I felt hot breath funneling into my throat. We made out for minutes as our tongues danced in the humid cavity between us. Finally, I broke the kiss and bit Twi’s lip gently. I knew my sister was ready for me because of our play prior.
“You sure you want to do this, Twilight? I don’t want to force anything to happen,” I asked. I already knew the answer, but I’d feel wrong if I didn’t hear it from her directly.
“Oh yes, Shining Armor; I wanna do it so much!” Twilight said, bursting with enthusiasm to try her first cock.
It was all the encouragement I needed. I reached around Twi and grabbed my throbbing colthood and lifted it. The maneuver proved harder than I thought with the eager pony on top of me. Still, I wasn’t about to ask her for help; I was the big brother, this was my job.
After some effort and light shifting, I was in place. The tip of my aching hardon rested against the warm groove under my sister’s tail. I looked her in the eyes again; I could tell she was nervous, but she nodded to tell me she was ready.
I lifted Twi under her forehooves and helped ease her backwards. She hesitated and paused for a minute as each inch went into her. My mind tried to push the pleasant enveloping sensation aside and focus on helping the filly with her first time.
“Ung! It’s too big!” Twi cried.
“You’re doing great, sis. Don’t worry, just relax.”
Slowly, we coupled. After the first few inches, I slid into her with ease. The incredible feel of her velvety walls squeezing me like a glove made my whole body relax. Twi sat back on my shaft slowly, trying to see how much would fit. Finally I bottomed out inside her with about an inch of me still exposed. A shame, but vaginas are known to be flexible.
“I can feel you in there!” Twilight said with a light giggle. We stayed like that for a minute, my thickness buried in underage sibling.
“Yeah?” I asked. “Do you like it?” She gave me a big, dramatic nod.
“I feel,” Twi paused to choose the right word, “full. Whatsit feel like for you?” she asked.
“It feels like I have the most wonderful sister in the world.”
Twilight smiled coyly. We cuddled together, our eyes adjusted to the darkness. It was incredible to finally know my sister inside and out; I felt so close to her. I brought her in for another kiss as our genitals became acquainted.
“What’s next?” Twi spoke, breaking our kiss with a strand of saliva still between us.
“Just move up and down on it, silly.”
I could have sworn the heat and pressure would’ve crushed diamonds, but when Twi started to rock her hips the pleasure increased tenfold. I coaxed her along with my hooves and thrust upwards to meet her with each backstroke.
“Nnng-” Twilight shuddered as I fucked myself deeper inside her. Our tails mingled and the dark bedroom began to smell of sex.
I hoped that the sounds of our love would not alert our parents, but the wonderful tugging of my sister’s tightness made the thought disappear; in that room there was only me and her. I wanted to please her so badly.
Sweat clung to my body and my blue mane fell heavily across my face. I sent it flying with a flick of my neck. Twiley and I were both panting together. The wet sounds of our mating filled my ears and heightened the experience.
To her surprise, I took Twilight’s head and brought it down, still bucking into her. I opened my mouth and found a tiny, purple horn with my tongue. I slurped all around the fluted appendage before consuming the entire thing with my lips.
Twilight gasped and moaned into my chest as I held her in my mouth. I sucked hard then released her with a pop before suckling once more. I could feel her pussy twitch as I played, giving my sister a sensation the likes of which she’d never dreamt of.
I knew she wouldn’t last long with the double stimulation and that was exactly what I wanted. My Twiley would never forget her first time, I would see to it. I continued to suck with vigor, preparing myself for her orgasm.
The horn lacked any truly distinct flavor, but the texture was electric. A tingling sensation coursed across my wet tongue like a live-wire and the thing itself began to heat as I drilled myself into her. Twilight’s body became like an instrument and I was determined to make beautiful music.
Both of us were lost in the passion. We murred and mewed together as I humped upwards, groping at Twilight’s moist back and bare flank with my hooves. I lifted up, driving my slick shaft into my sister’s warmth, fucking her, filling her. I’d awaited this moment for the past couple days, yet I never expected it could be this good.
“Ng...ng…ng… I… I think- I…” Twilight sputtered as the full force of her pleasure began to mount like a tidal wave ready to engulf her. I circled her buzzing horn with my tongue and held her tight as I bucked faster, getting the best workout I’d had in weeks. Her coos increased in pitch and volume as our hips slapped together, her body now flexible enough to take my entire length.
The horn in my mouth vibrated and my thrusts failed to escape the vicegrip of the young pony’s pussy as she plunged headlong into orgasmic bliss. The tightness was too much. My own pleasure welled up and exploded into her waiting body. Spurt after satisfying spurt of liquid love left me and tickled my sister’s insides.
Primal grunts left my mouth as I came. Hot jets of semen flooded my sister, pooling in her belly, unseen as we rode the breathtaking gift exchanged between the two of us. Twilight gasped as she felt it inside her and she flinched in time with my pulses. My mouth began to taste of sweet syrup and I realized then that Twilight had had not one, but two orgasms. I swallowed what I could from her leaking horn and licked it clean.
As our orgasms passed, our bodies collapsed and I reveled in the weight of my sister on top of me. Time stood still as I hugged her, our heavy, open-mouthed breaths mixing in the darkness. She looked up into my eyes and stared hazily until we both broke out in soft giggles.
“Oh my, that was fun,” Twilight said.
“Y-yeah,” I murmured.
I popped naturally from Twi’s worn pussy as my penis softened and retreated. The fruits of our love spilled out and dribbled into my lap. I pressed my muzzle against Twi’s and let my eyes tell her that I loved her. I really did love my sister, more than I think she knew even. I would’ve done anything for her, to see her continue to grow.
“I guess you’re not quite my ‘little sister’ anymore, huh?” I said teasingly. Twilight giggled.
“Well, you’re definitely a ‘big brother’!” We laughed together at the lewd joke.
“Oh Twiley, you silly filly,” I paused and enjoyed the moment. “I suppose we’d better clean up, huh?”
I pushed Twilight to the side and started to get up. She followed me to the bathroom where we bathed together just like old times. When we were good and clean I put her to bed with a kiss on the cheek and retired myself.
I lay awake that night for some time thinking about what had happened. It was an incredible night, but I still had my doubts. I knew Twilight wouldn’t tell anyone, that wasn’t my concern. I was worried about how she would react and what our relationship would be like from now on. I loved my sister to death, but I didn’t want to just be her lover or plaything. I couldn’t be.
The next day I had a talk with Twilight. She had no regrets and told me I’d always be her big brother. It was a touching thing to hear from my gem of a sibling. I told her that we could do it again if she wanted, but said we shouldn’t make it a habit. I wanted it to be special, like it was last night. Twilight seemed to agree and trusted my wisdom, despite some obvious disappointment.
That was the start of a wonderful chapter in our lives. I never looked back. Were there some things I could have done differently? Probably, but I wouldn’t have traded the outcome for anything in Equestria. The two of us did everything together, it only felt right to know each other intimately. I said this wasn’t the most flattering story, and I still have reservations about what I did, but only when I’m alone. When Twilight is near me, all of my thoughts are of love for her and I know regardless of whether it was right or wrong, that everything will be alright.
