Chapter 1

“Hey, big guy, time to wake up.” I heard a melodic male voice call to me, pulling me from Luna’s realm. I opened my purple eyes with a few blinks and saw him, the love of my life; my big brother, Thunderlane. “That’s more like it, champ. I’ve got breakfast ready for you, let’s get it while it’s hot.”

I couldn’t help but smile and think about how hot he was. His dark gray fur, his cropped two tone mane, and the fact that he was a flier in the Wonderbolts. He had mares over every so often to fulfill his adult needs, and he was practically my parent; but that would be weird. I didn’t look at my dad the same way I looked at Thunderlane. I couldn’t, he wasn’t in my life like my big brother was.

I nodded and got up as Thunderlane turned away and flicked his tail, showing me what I needed and someday would have filling me up. He didn’t know how I felt, and it hurt to know he might not feel the same. But, someday I’d tell him and we’d make love like lovers do. I know I’m still young, but I know what sex is. I masturbate and have had some experience with sex.

Snails let me lick his penis and he did the same to me, to see what it was like. I loved it but he said it reminded him of licking a cooked carrot. I took it as a compliment, but that was as far as it went. He didn’t want to try anything more. Not like I wanted to. I often do stuff in the bath or shower. I think of how good it will feel and sometimes I use shampoo bottles or the plunger handle, imagining what it’ll be like when my big bro mounts me and fills me with his stallionhood.

But, it’s not the same as what I think the real thing will be like.

“I’ll be there in a couple minutes, I’ve gotta go to the bathroom.” I tell him and rub my eyes with my forelegs.

“Sure thing, I’ll plate you up.”

I hurried to the bathroom, hiding my erection as I watched his hips sway with each step, teasing me. I closed the door and sat down, wrapped gray my fetlocks around my penis and started stroking. A minute later I got the shivers and watched as my penis went soft, then receded into my sheath. Sighing, I finally went to the toilet to pee and then washed my forehooves.

I could handle this. It’s just another start to the day with my brother. The sexiest stallion I know, sitting so close to me I could hold his giant hoof with mine. Lean in. Press my snout to his. He’d push me back and roll me to my belly and nibble my ear.

I shook my head. I had to stop thinking of sex so much, it wasn’t going to do me any favors until we started doing it. I left the bathroom and went to the kitchen, smelling breakfast and when I walked in my brother was wearing an apron; a silly thing that was pink with lace frills. I giggled at him.

“What? This old thing?” He used one of his strong wings to pat the apron. “Sit down, buddy, and let’s eat. I’ve got oatmeal deluxe this morning, then after we eat I was thinking we could play catch for a little bit before school starts.”

I took my seat on the floor by the table at my spot and he served me a big bowl of oatmeal deluxe.

Breakfast was good, but it was a school day so I had to hurry and eat. I didn’t really like how quickly the morning passed. One hour was all I got before I had to go to school for a tiring six whole hours surrounded by fillies that don’t know about my sexual preference or the stallion that holds my heart in his hooves.

I have to keep up the act of being like my brother, even though fillies gross me out. They’re smelly, leave wet marks when they sit, and try to tease us colts by flicking their tails to show us their gross slits that smell weird and make me feel funny, but not in a good way. I want to push them into the grass whenever they do that, but I know I’ll just get into trouble.

I have time to go outside and play catch with my brother for a little while and work on my flying while I do, hovering and chasing the ball above the ground before I have to land to pick it up and throw it back. I miss more than I catch, but it’s okay because that’s how I’m gonna be a great flier like Thunderlane.

Time comes to go and I hurry to get my saddlebags on, my brother comes to help cinch my girth strap and I secretly smell his coat. He smells like the shampoo from the bottle I stuck halfway in my butt, thinking of him. I smile and feel the muscles inside me relax a little, letting myself drop out some.

“There ya go, little bro. Woah, you’re showing a little. You should put that away before some filly sees it and-”

I flap my wings and get some primaries in his mouth to shut him up. “Gross, bro. That’s the last thing I want.” I say, grimacing. He thinks it’s because of the fillies, but I just almost let slip that I prefer colts and stallions. Well, stallion.

“Message received. Still if you need a couple minutes to take care of it, I won’t tell.” He teased. I blushed bright enough to be seen and I receded. “That’s more like it. Save it for, what’s her name, Silver Spoon?”

I gag and stick out my tongue. “Grosser! She’s a total girly girl and is totally not into me like that.”

He laughs and it sends my heart aflutter before he ushers me to the door and pushes me out, his snout against my tail that’s barely covering my balls. His snout was practically huffing my balls and all I could think about was telling him my secret and staying home that day. Buck school and everything, this could be the day.

“Okay, I’m going.” Maybe not.

“See you later. I have Wonderbolt practice, then a few things to take care of. I won’t be back when you get home, but I’ll be back to start dinner for you.”

He waved at me as I left, hovering just above the ground to show off. Once he stepped back inside I landed and hurried down the dirt road to school. Once there I sat at my desk by Snails. He was cute in how dumb he was, how proud of that fact about himself he flaunted it around town.

It was undeniably cute, innocent and made him one of the sexiest colts in class. I talked a little with him and Snips about after school activities and places to play, including the new games at the arcade. Button Mash and Pip came into the conversation at that point and we all agreed to go home and collect a few bits then meet at the arcade around two in the afternoon.

Ms. Cheerilee called class to start and we all took our seats, most of us losing interest in the current lesson of pre-calculus and how it would be used in our everyday lives once we got both our marks and an apprenticeship. All I could think of was seeing my brother’s balls that morning. His tail swaying, his hips bouncing…

“Ew! Ms. Cheerilee, Rumble’s showing again!” Silver Spoon called out to the class, getting them to all look at me as I tried to hide my erection. I pulled a book from inside my desk to cover as much of it as I could.

The whole class giggled and laughed at me. It’s not like I was the only colt to get turned on during class, but Silver Spoon has an obvious crush on me, and typical fillies tease those they like the most.

“Now, class, don’t be mean. Everypony has moments like these, even you, little miss.” Cheerilee said.

Silver Spoon rolled her eyes. “I don’t have that problem. Mine doesn’t show when it happens.”

Ms. Cheerilee sighed and hurried over to me, standing between me and the gray bitch. “Are you okay? Do you need a moment in the back alone to take care of it?”

I blushed fiercely and shook my head, concentrating on seeing fillies flicking their tails to hurry it down. “I’ll be okay. It’s already almost gone.”

“For now,” Diamond Tiara shouted getting most of the class to laugh again. I looked around and saw nearly everypony except Scootaloo and Apple Bloom laughing, they were leaning in to whisper to each other. I swear by how they act they’re as gay as I am, only it’s acceptable for them to be.

Celestia forbids a colt or stallion is gay, taking away from the gene pool.

Thinking that was the last straw and I was able to set my book back in the desk. Ms. Cheerilee moved back to the front of class and resumed her lesson. I saw Silver Spoon taking notes, but then I sat back to see what she was writing; she was drawing penises. Nice ones, too. Big, meaty ones with huge sacks.

She caught me looking and gasped, blushed, and shoved the paper into her saddlebag before she was caught by anypony else. All I could do was smirk. “Like what you saw?” I teased her under my breath. Her ears turned to me while she sat straight at her desk. “I got more where that came from.”

I liked seeing her shift in her seat, knowing she was getting bothered by my teasing. I chose to stop, though. Thunderlane said I had to be the bigger pony when it came to teasing, after all.

“Ms. Cheerilee?” Silver Spoon called and raised her foreleg. I rolled my eyes, ready to be teased again.

“Yes, Silver Spoon?”

“Can I go to the restroom?”

Buck being the bigger pony. “She just needs to rub one off, Ms. Cheerilee.”

“Rumble!” The teacher scolded me, harshly. Silver Spoon blushed from her neck to her ears and she glared death at me. “We do not call other ponies out like that, am I understood?”

“Yes, Ms. Cheerilee.”

“Silver Spoon, you may go and you don’t need to explain yourself now or when you get back.”

Silver Spoon hesitated, then got up to go.

“Don’t forget to wash your hooves when you’re done,” I said as she started to make her way down the aisle.

Silver Spoon’s tail clamped down and she hurried, lowering her head as she passed the teacher, who was making a beeline for me. “That’s it, young stallion. You’re staying after class to help me clean up.”

“What?! But, I was gonna-”

“You can either help me, or I can tell your brother about you being mean to your classmates.” Cheerilee was clearly being the adult and I couldn’t help but cower under the look she gave me. I couldn’t risk Thunderlane finding out I was mean to a filly that liked me, it wouldn’t make me look good in his eyes, for certain. I just nodded my head and stayed quiet. “That’s better. I’d suggest you stay silent when she returns, or you’ll be doing double duty.”

I nodded again, trying not to frown. She turned to walk away and I stuck my tongue out at her, it was all I could do, after all. The lesson resumed and I glanced at the clock. It had only been ten minutes since school started.

It was going to be a long day.

Chapter 2

I had to get home to wash the chalk dust off of my coat before I could play with my friends, this time nothing went wrong and I got into the shower to wash and was outside within half an hour. I hated having to groom a bit, but going outside wet would mean I’d end up covered in mud and that would mean another shower before bed.

I met Snips, Snails and Featherweight at the park and Snips had a bag with various balls and toys we could play with sitting next to him. I was late, but they waited for me to decide what to play as a group. Naturally I picked tossing the hoofball around while they wanted to start with playing catch with a wiffle ball.

As much as I want to have balls in my mouth, it’s not how I wanted to start playing after school. Well… I did, but… you know what I mean.

We ended up playing catch with the hoofball and me and Featherweight practiced our flying while the earth ponies practiced standing on two legs or throwing with one foreleg between us all. It was fun and I didn’t end up thinking about my brother or sex at all during the whole time we played.

We played tag, hide and seek, and ended with catch. I learned a long time ago to just use my teeth and keep my tongue back from the ball. I didn’t want to taste spit and grass from another pony unless it was with Thunderlane. Finally we packed it all up and let Snips take the bag, and the cute colt, back to his house to do things I could only imagine. Featherweight left to meet his big brother at a restaurant.

How a pony could get so much muscle mass was kind of gross. I don’t mind the strong type, but he’s at an extreme. He’d probably crush me with a hug, not a turn on, to be honest. Now, if Featherweight could get some more muscles and not be such a pencil… I think I could have a crush on him, if that happened.

I got home and went to my room to read a book while some music played in the background until I heard Thunderlane call out that he was home. My heart skipped a beat and I rushed to turn off the music before hurrying downstairs to hug him.

“Woah, little bro. Don’t hurt me in front of my date. This filly killer is my little brother, Rumble.”

“Date?” I asked and looked at the doorway to see a yellow pegasus mare smiling at us.

She brushed her green mane from her eyes and smiled. “Oh, he is cute as a button. Hi, my name’s Sky Shard. I’m a big fan of your brother’s.”

Sky Shard. The new mare of the night. I didn’t want to hear them having sex all night in the room next to me, so I had to be cold towards her. Not too rude, or I’d be sent to bed without supper and still have to suffer hearing them moan and the bed squeak. “Uh, hi,” I said as I let my brother go.

“Yeah, I met her while I was signing autographs and we hit it off.” Thunderlane said to me. He leaned down to whisper while Sky Shard stepped in and looked at the awards wall. “Don’t embarrass me, she could be the one.”

“So what? Like the last dozen weren’t?” I grumbled back.

He glared at me and I glared back. He turned away to move next to Sky Shard and then he started bragging about his awards to the stupid mare. “Wow, you have so many awards, you must have always been great.” She tittered. Just like Diamond Tiara. Both stupid bitches. Both useless except for one thing.

Don’t think I don’t know about how Diamond Tiara lifts her tail for any colt, then uses their inexperience as leverage against them. Threatening to embarrass them for finishing too quickly or not knowing what to do, or so she says. She’s as awful as the rest of them. Except Scootaloo, she doesn’t seem to be into anypony, just getting her cutie mark.

I rolled my eyes and went back towards my room. “Call me when supper’s ready.”

“Okay.” Thunderlane called back as he pointed to another flying award to explain about it.

I went to my room and went back to my book. It was a good story about a puppy that lost its pony and was trying to find her in Manehattan. I was reaching the halfway point, I think, when everything went silent in the house. I noticed because all I could hear was the ticking of the clock in my room.

I went to the door and listened and didn’t hear anything. I flew to the stairs and listened, then heard the sound I knew to be kissing. I couldn’t believe how fast this mare was moving! Barely an hour in my house and she was seducing my brother already. Probably just trying to get bragging rights for her friends.

What if there was a competition for who could get the best Wonderbolt? That would explain why so many mares keep hooking up with my brother. There was a flurry of wings and then more silence for a moment. “Stay quiet, don’t let the kid know what we’re doing,” Sky Shard said.

“He’s in his room, he isn’t coming out until I call him. Just…”

Then more silence until I heard her moan and hooves clatter on the tile of the kitchen. My eyes widened as I realized they were probably having sex before supper was ready. That bitch was in my dream position before we ate. My heart was burning with anger and I flew back to my room. “Thunderlane, how’s supper coming along? I’m getting hungry.”

“It’s coming, alright.” He called back and they both snickered. He just made a sex joke at me and didn’t think I knew about it. He was being a jerk and I hated that about him right then.

I couldn’t say anything or else he’d get mad at me, so I just closed my door and walked around my room, thinking of what I could say to get her out of the house so I could tell him about what I thought about her. I couldn’t stand to see that mare for the next few days until she got tired of him and moved on.

I glanced at the clock and after a few more minutes of pacing, after a few long minutes of thinking of them doing it, I finally had enough and opened my door and stomped to the stairs. I made as much noise as I could to let them know I was coming before they did and went downstairs to the living room and climbed up on the loveseat.

“Supper’s almost ready,” Thunderlane said as he led Sky Shard to the couch. They both seemed a bit out of breath and their manes were messier than earlier. She was carrying a towel and tossed it on the couch before she climbed up onto it. My eyes widened and I realized they’d finished already and he had finished inside of her. The towel was to catch anything that spilled out from getting on the couch.

Instead of feeling anger, I felt sad. It wasn’t me that was with him. It was this cheap mare that had no shame or humility. She literally lifted her tail ten minutes into coming into my home. My feelings must have shown because she looked at me with pity in her eyes. “What’s wrong, big guy?”

That flipped it for me. “Nopony calls me big guy but my brother, who I love.” I said, feeling myself sneering a little. She raised an eyebrow.

“Sorry, I was just wondering.”

I looked at her tail and hated thinking of it brushing against my brother’s belly. “Well, don’t.”

She got up and started walking around the room looking at photos of my family while I thought about what not to say.

“Supper’s ready!” Thunderlane called out. She hurried to the kitchen while I dragged my hooves. I sat in my spot at the table and noticed the smell of mare. Thunderlane was bringing plates to our spots as she sat to my left. Thunderlane set his plate to her left so he’d sit across from me before he brought a plate of fried hay for us to start with.

She took a pinch before I did and we both ate. It was really good. He put a plate of baked tofu next and then a plate of steamed vegetables. I took a scoop of each and glanced at Sky Shard as she took her first bite. “Mmm, it’s really good. Are you sure you’re not a mare under a spell?”

Thunderlane laughed. “If I was we couldn’t have fun like we did.”

They both glanced at me. No, my place at the table. It clicked and I swallowed my mouthful. “You… didn’t?” I asked them both.

“Didn’t what, big guy?”

“You had sex at my spot at the table?!” I shouted, hopping to my hooves.

They shared a quick look. “I don’t know what you’re talking about. We haven’t even had supper yet.” Thunderlane said.

“I heard you! But I didn’t think at the table, at my spot!” I yelled at him.

“Look, kid-”

“I’m not a kid, lady,” I started, “I have a name.”

She held up a hoof. “Sorry, Ramble, I-”

“My name’s Rumble! And he shouldn’t be having sex with you, he should be doing it with me!” I squeaked the next sound as my eyes widened, as did theirs.

She snapped her attention to Thunderlane. “You fuck your brother?!” She shouted.

“No! I’ve never even thought about doing that! Rumble, what are you talking about?!” Thunderlane shouted at me with worry in his expression.

I was outed and not how I wanted; I wanted to die just then. “I… I love you,” I managed as I took a step back and opened my wings.

He snapped his wings open. “Don’t you even think of running away right now. I’m sorry, Sky, but can we have a private moment?” She was outright mad and confused. She nodded and quickly left the room leaving us alone. “Would you mind explaining what you mean, Rumble?”

I kept standing, now worried about what I had been sitting on, or in. “I… just, love you, Thunderlane. Is that a bad thing?”

He partly closed his wings. “When you say love, you mean, as in…”

I looked into his golden eyes. “I… want you to be my first, and last. I only want to be with you,” I said, hoping to see the same in reply, “forever.”

His exhaled and closed his wings, sitting and pressing a forehoof to his temple. Nearly half a minute passed before he mumbled. “I’ve heard of this happening.” He looked up at me. “It’s not a problem that you’re gay, just that you can’t do that with me, or family in general. It’s not right to do that with family. What about other colts in your class? Are any of them…”

“No, and I’ve tried a little. I’m the only one in town, I think.”

Thunderlane snerked. “You’re not the only one, trust me. But, you have to wait to find the right stallion, and I’m not it.”

“Yes you are! You’re sexy, funny, smart, a good listener, and everything I want in a lover.”

Thunderlane sighed. “You sound like every mare I’ve met. Look, Rumble, I’m sorry to break your heart, but I’m not the one for you. I know it’s not what you wanna hear, but someday you’ll understand better. You’re not even ready, physically, for a stallion. Can you think of how hurt you’ll get if somepony my size does anything to you? My dick is almost as long as you are, for Celestia’s sake.”

I thought about it and it made sense. A lot of sense. “But, what if you only use half of it?”

He laughed. “That’s not how it works, buddy. Look, I’ve got a mare here for me, doesn’t that tell you something? If I wanted a stallion over, I could have one and it wouldn’t be a problem. Someday, when you have a boyfriend over I’ll understand, but you have to get it through that tough noggin of yours that you have to not only stick to your age group, but stay away from family.

“Can you imagine what would happen if we did end up doing anything together? It would be the end of my career as a Wonderbolt and it might even land me in jail, unless I could convince them I was just helping you. And even then,” he interjected before I could say my agreement with that idea, “you’d have to do that to me, and I don’t think I’d like that.”

“Why not? Why not give it a try before-”

“Because I’m not gay, Rumble. At all. I love mares; probably for the same reasons you don’t like them.”

I didn’t know what to say. I couldn’t say anything. My heart was in my throat and I could barely see. I hiccupped and felt my brother hugging me as I started to weep. “But…”

“It’ll be okay, bro. You’ll find the one for you, it just isn’t me.”

I cried after that and let loose all my feelings for the next I don’t know how long into my brother’s chest. Eventually I stopped and wiped my eyes, but still felt sad. He was looking down on me with such kindness. “Do I… have to go to my room now?”

“Not if you don’t want to. We were having supper, would you like to finish?”

I nodded a little, but didn’t feel much; I felt kind of numb. Sky Shard came back into the room and sat in her place again. “Rumble, I understand you’re going through a lot of feelings… but my little cousin might be your type. He’s in Cloudsdale right now, but if you want, I could introduce you and see where it goes.”

I reached and grabbed some more hay. “I… might like that. Is he nice?”

She smiled. “He’s a darling little colt and I think you two would be nice together.”

As I slowly chewed my hay I thought about it and liked the idea. I nodded. “I’d like to meet him. What’s his name?”

“Flutterwing. He’s white with a blue mane.”

“Do you have a picture of him?” I asked.

She giggled and reached to place a forehoof on my brother’s. “Not on me, but I can fly home tomorrow and bring one back. After all, you’re worth the flight.”

I still felt sad and kind of numb, but overall, hopeful. My feelings for my brother quickly seemed to change and now the thought of Flutterwing danced in my head. What if he was the one for me? “Wait, if you two get married, wouldn’t that make me and Flutterwing family?”

They both stopped chewing to share a look. It was thoughtful. “We’ll cross that bridge when we come to it.” Thunderlane said.
