The Year 5000: Chapter 6: The Sigma Male
By
Varos

It's Sunday, July 31st, 4998.  School officially starts tomorrow.  Today also marks the end of our summer job.  I managed to put $11,600 in the bank, and so did my not-so-little little Brother.  It was a good amount of money for only 2 months worth of work.  Our Mother has no idea how much money we made, and I made damn sure to keep it that way.

I'll be a junior this year, and my Bro will be a freshman.  This is the year where I get to choose whether I want extra classes.  Most furs my age elect for the easy route and fill the empty slots with study halls, but not me.  I don't know exactly what I want to do when I graduate.  I decided to cover my bases.  I maxed out on every slot.  I will have a lot of homework this year, the most I've ever had by far.

It's early Monday morning, August 1st.  Our Mother is off from her job on the night shift.  She says goodbye as my Brother and I head out the door.  She was home all night, so we had to sleep in our own beds.  Yesterday was Sunday, so we had the day off.  Our summer job is over until next year.  We didn't do much yesterday; we mostly lazed around the house.  Zack joined me, and we took turns reading to each other from an adventure sci-fi novel.  Our Mother finds it weird, but we always leave a respectable 3 or 4-foot gap between us so it doesn't appear too hinky.  We're both nerds, even though our overly muscled bodies would suggest otherwise.  She doesn't quite understand our desire to use our brains.    

We did manage to get in our morning and evening workouts.  We, of course, went for a long walk in the middle of the day.  That's not unusual.  We've done that for years.  My plan for fucking in the abandoned house up the road from our house has been a god sent.  We make full use of it whenever needed, and yesterday, we needed it.  Eventually, it'll start to snow again, and we'll be forced back inside.
  
We told her we were going for a walk.  Instead, we went to our little clubhouse, and we fucked like wild animals.  We weren't about to waste the opportunity.  We won't be alone again until she starts another work week on Wednesday.  For the next 2 days, we'll have to be satisfied with jerking off in the shower.  We didn't have time for anything fancy, but it didn't mean Zack would skip on the roughness.  I got it far worse than I gave it.  Zack knows I prefer to bottom.  We didn't play any games; we had just enough time to pump and head home, but not before we cleaned the cum from our black fur.           

The air is cool and crisp.  It's a nice reprieve from last week's hot and humid weather.  The sky is cloudy.  Both of our canine noses sniff at the air.  We can both smell it; rain is approaching.  I follow behind my Brother's swishing tail as we head out to catch the school bus.  It looks like it's going to rain at any second.  I wait with my 15-year-old Brother at the end of the driveway.  We feel sprinkles fall lightly on our long wolf ears.  The school bus pulls to a stop in the nick of time.  The door creaks open, and we climb on.  The bus pulls away as the sky opens up.

It's a gloomy morning, but it's also invigorating.  I see all the same familiar faces, minus the ones who graduated a few months ago.  My Brother and I sit together towards the back of the bus.  Our clothes are baggy.  Neither of us likes to show off or draw any unwanted attention to ourselves.  Baggy clothes can only hide so much.  I have a decent amount of muscle.  I'm on the lighter side of a lightweight, but I have more than enough muscle for people to take notice.  Zack, on the other hand, has difficulty concealing his size, even during the middle of winter. 

Any straight male who I'm not friends with will either steer clear of me or want to fight.  The females aren't exactly subtle with what they want.  I've been running out of excuses.  I know this year is going to be bad.  In a way, I'm glad I have a full workload.  It'll help me rearm myself with better excuses for why I can't enter into a relationship with them.

I would hope being a freshman would make Zack's experience easier.  In some ways, it will.  No male would dare risk getting into a fight with him.  He's already as big as most seniors.  That won't be a problem for him; the bullies will simply pick on easier targets.  On the other hand, the females will be a completely different problem, especially once they figure out that he has the brains to go with the brawn.  I warned him about it as best as I could, but I don't think he fully comprehends what he's walking into.

The bus rolls to a stop, and we make a mad dash for the high school's front doors.  Furs only wear shoes if there's a good reason to.  Usually, it's work-related.  I've only worn shoes a few times, and I remember I hated them.  I need to feel my pads against the ground.  This is one reason why I love the rain.  I love feeling the rain between my toes.

I walk through the school's main entrance, with Zack following right behind me.  My Brother and I shake the water from our fur like dogs.  I pull my feet through the rug to wipe away the worst of the mud.  It smells exactly the same; it feels like I just left yesterday.  Having my younger Brother at my side feels so weird and yet refreshing at the same time.

I know this place like the back of my hand.  Except this is Zack's first time here.  I feel the big brother in me take over.  I can't stop the compulsion to help him.  I turn and ask him, "So, where's your locker?  I'll see if I can help you find it."

"Ahh, it's #967," he says with a sneaky grin.

"Wait, really?  That's right next to mine."

"Yeah, I know it is.  I asked for a locker next to yours, and luckily I got one."

I smile to myself as I know why.  I lead my Brother down one hallway after another.  Lower numbered lockers start in the front of the school and increase the further back you go.  Most students want the lower numbered ones as it makes coming and going much easier.  I point out a few of his classrooms along the way.  I find my locker #969.  I'll get new books at the start of each class, so I don't have anything to put in it at the moment.  Zack finds his locker and tries out the combination.  He spins the dial, and it opens with the familiar clang of metal on metal.
"Hey, Alex."

I hear the familiar voice from behind me and know who it is.  I turn around and say, "Hey, Chris.  Hey, you remember my Brother Zack, don't you?" I say as I gesture toward the larger wolf with matching solid black fur behind me. 

The yellow lab and greyhound mix eyes widen as he realizes how big this unfamiliar male really is.  He doesn't recognize him, but I see the wheels start to turn, and then it clicks.  Chris is taller than me by a few inches, but Zack has him beat by about 5.

"Oh yeah, hey, Zack.  It's been so long that I didn't even recognize you.  I think the last time I saw you, you were like this tall,' says Chris as he holds his hand up level with his belly.  

I can see Zack is having the same problem.  It takes a moment for him to remember who he is.  It's been at least 5 or 6 years since they've seen each other.  Zack's ears perk up, and he gives him a friendly smile and says, "Oh, hey, Chris.  Yeah, it has been a really long time, hasn't it?  But it's nice to see you again."

We both see the yellow lab mix looking the larger wolf over again.  It's obvious that he's sizing him up.  "Damn Zack, you really shot up like a weed, didn't yea.  You have to be at least 6 inches taller than Alex now."

"Actually, he's 7 inches taller than me," I say with amusement.

"Damn, that's crazy.  At least you two aren't trying to kill each other."

"Yeah, don't tell anyone, but we actually get along great.  We're actually each other's workout buddies."

"Yeah, I remember you mentioning that.  Damn it, now I wish I had a brother I could hang out with," says Chris.  

"Hey Chris, I'll catch up with you later.  I need to show Zack where his first class is."

"Alright, and it was nice seeing you again, Zack."

"Yeah, you too, Chris." 

Chris continues on down the hallway.  There's little time left before the first bell.  I walk Zack to his first class, "alright, I'll see ya at lunch," I tell him.

I don't say anything as I walk away.  I don't like it.  It feels too cold and uncaring for me.  There are too many people around.  Being neutral with your siblings is okay, but being too friendly isn't a good idea.  I don't need to apologize; he knows the reasons why just as much as I do.  Being gay isn't a problem for furs.  Nearly a third of the population is homosexual.  You'll see guys making out in the hallways in a high school.  You'll see everything else, too, but making out with your Brother will turn some heads.  Maybe someday we can be ourselves in public, but that'll only happen in a faraway place where people don't know we're siblings.

Chris used to be the leader of our little group of 4.  Chris is a half-yellow lab and half-greyhound mix.  His fur is all yellow with white on his neck and chest.  He's taller than me but no longer as bulky as I am.  Despite my masculine physique, I'm still a nerd.  Things started to change with him at the start of our sophomore year.  I know why.  It was his hormones.  His attention quickly turned away from his friends and more toward the females.  He's had a lot of girlfriends over the last year.  He has very much become the fuck and forget type.  We've never stopped being friends; we just started to drift apart.  

My first class was A.P. English; after that, it was computer science.  I was looking forward to the second one.  After that it was calculous, and then lunch.  I know I'm a bit of an odd wolf.  Humans didn't create us to be intellectuals.  Extreme intelligence would only be a burden on your common everyday worker.  Obviously, they did create some extremely smart furs; otherwise, I wouldn't exist.  Even the advanced classes were easy for me.      

The bell rings, and I make my way toward the cafeteria.  I'm a wolf, and I can't help but sniff the air along the way.  So many new scents and so many familiar ones are missing.  One I remember all too well hits my nose; it's meatloaf day.  I get my lunch and exit the line.  Like always, I head to an unoccupied table at the far end of the cafeteria.  I set my tray down and take a seat.  I see a familiar black wolf in line.  I see my Brother scanning the room.  He sees me, and I see him relax. 

The cafeteria is vast.  It has enough seats for over a thousand students.    I scan the new faces while I wait for my Brother.  Seeing furs smaller than me feels weird, but that's only because I'm a junior now.  That's not always the case; my Brother is a prime example of that.  We both got stuck with the second lunch period, but at least we got to be together.  It explains why there are already food messes everywhere.

Furs of all species mill about the cavernous room.  The volume grows steadily louder.  Friends reunite.  The freshman wander around looking lost.  The room is filled mainly with the big 3 canines, felines, and hoofs.  A few bears are sprinkled into the mix, but they're far less numerous.  I don't know how many bears are at school this year, but there were just 12 last year.
  
Humans could have modeled us after any species they wanted.  But even if they wanted to, there was one thing more powerful that stood in the way, and that was the market.  They wouldn't invest billions into an unsellable product.  Our population is almost evenly divided among the big 3.  I really do love the diversity.  Smaller furs are usually either canine or feline.  Furs modeled after domestic cats were popular, but they didn't exclude the smaller wild ones either.  Dogs, coyotes, and foxes make up the smaller canines.  Goats and rams take up the small side for hoofs, but they're rare.  Some of the smaller breeds might only grow to be 4 feet tall.  You can imagine what humans used them for.

Medium-sized furs are the most numerous, while larger ones are less so.  Big furs were modeled after big animals.  It explains why my Brother is so huge.  It wasn't a rule that was set in stone.  There are plenty of medium size wolves as well.  It explains why I'm not as big as he is.

I couldn't imagine living with humans.  Seeing the same pudgy faces everywhere you look.  They didn't intend for us to supplant them, at least not the ones on this planet.  There are more of them out there somewhere among the stars, but they haven't returned in nearly 2000 years.

Most furs, including myself, look exactly like the animals we were modeled after.  While others are far more exotic.  I see some of the wildest-looking colors and patterns you can imagine everywhere I look.  A fennec fox with neon blue highlights.  A domestic cat with green fur.  Seeing a fur with no markings and all one solid color is extremely rare.  In a way, it makes my Brother and me stand out even more.  At least our golden eyes give us a tiny bit of color.            

Zack walks up and takes a seat across from me.  He sets his tray down as I swallow the meatloaf in my mouth.  I got my mouth half open when a mountain lion sat to his left, and a red fox took a seat to his right.  They're both obviously first years.     

"Hey Vance, hey Jacob," I say.

The entire time Zack's been friends with Vance and Jacob, I've only seen them for maybe a total of 24hrs.  I remember who they are.  Zack talks about them every now and then.  Vance is the mountain lion.  My eyes go wide as I realize he looks nothing like what I remember.  Vance is way bigger than I am but still smaller than my Brother.  The last time I saw him, he only reached as high as my chest.  He must have genes like my Brother because he shot up like a weed.  He's taller than I am by at least 4 inches.  He has to be at least 6 feet tall.  His clothes are baggy, just like the rest of us.  He's not trying to flaunt his body.  His shoulders are broad, which tells you he's a male you probably shouldn't mess with.  His shirt hangs from his chest, indicating he has more than your average amount of muscle.  His T-shirt covers his upper arms but reveals just enough to let you know he works out, which is only confirmed by his equally muscular forearms.  From what Zack has said, Vance does work out.  I'm pretty sure that Zack is his source of inspiration.  

Zack's other friend is Jacob.  He's a red fox.  I have to admit that he's cute, but unlike my Brother and Vance, he's tiny.  He's 4 feet tall at most.  And unlike his friends, he's as skinny as a toothpick.  His head only reaches up to Zack's belly.  

They both look lost.  They couldn't figure out why their friend would choose to sit next to some wolf whom they'd never seen before, and then that wolf greats them by name.  Their eyes light up as they realize who I am.

"Oh, hey, Alex," they both say in unison. 

My friends have never met Zack's friends before.  If things weren't awkward enough, my other two friends found me.  They both hesitate until I motion for them to join us.  I see Chris in the background, but he's with his new group of friends who share his interest in chasing after females.

We go around with introductions.  I'm the default leader of my group now, and it's obvious that Zack is the center of his.  Brent, the coyote, sits alongside me, and so does Simon, the silver fox. 

Simon is the first to speak as he blurts out.  "Holy shit Alex, that's Zack?  I know you told us he was big, but I didn't think he would be that big."

"Ahh, hi, and ahh, Simon, right?" says my Brother as his ears dip in embarrassment.

"Ahh yeah, I think we met once, but it was years ago.  You know when you weren't big enough to eat someone," says the little silver fox, clearly trying to tease the newbie.
								
My Brother turns his attention to the coyote sitting to my right.  I'm about to open my mouth when Simon does the introduction for me.  "And the pouty coyote here is Brent.  Don't mind him; he's a nice guy once you get to know him.  He's just pissy because his parents suck."

The grey-furred canine says, "Hey," as he gives everyone a quick fangy smile, and it's apparent that he is a bit down.  It can be expected when coming back to school again.

I know that my Brother is the leader of his group.  His two friends wait for him to speak up, and he doesn't disappoint them.  "Ahh, and this is Vance,' says my Brother as he gestures toward the huge mountain lion on his right.  'He looks nice, but don't let that fool ya because he will eat you," he says, as he gives the big cat a playful nudge with his elbow.

Vance's ears dip in embarrassment as he says, "Hey everyone.  And now that I see you two together, you two could almost be twins.  Except for, you know," he says as he trails off, not wanting to point it out.

"The fact that he's almost twice my size,' I say with a huff as I interrupt him to address the elephant in the room.  'Yeah, but don't worry, he's okay." I say, not wanting to sound too brotherly in public.

"And this is Jacob," says Zack, introducing the tiny red fox to the group.  

I had already told my friends that Zack is taller than me now, although it was in passing conversation.  Except for Chris, who was off with his new group, I'm taller than the rest of my friends.  Which makes my Brother's size even more of a shock to them.

Things got really nerdy really quickly.  There was an awkward moment and a bit of awkward small talk as everyone adjusted to the new faces.  Once the ice melted, it was apparent that we all have a lot in common.  I had a feeling that despite just meeting, our two groups would become one in no time at all.

The breaks give off a loud screech as the school bus rolls to a stop.  Two wolves with matching black fur and golden eyes exit like they've done hundreds of times before.  Dust is kicked up in all directions as the bus pulls away.  I check the mailbox, and for once, there's no mail, not even a package.  

We don't have any neighbors other than the abandoned house up the road, which doesn't count.  Our next closest neighbor is at least half a mile south of us.  Our Mother goes back to work tonight.  We can both feel it, the anticipation of what's to come.  There's no masturbation tonight.  Tonight we're free to do whatever we want.  We're always pent up on Wednesdays.  Our Mother works a rotating schedule.  One week she works 3 days; the next, she works 4, and then it repeats.  Depending on her schedule, we can go 4 days without having much fun.  

The clubhouse idea I came up with helps a lot, at least until winter gets here.  After that, we're screwed.  The anticipation of waiting for her to start a new work week will be rough.  The only thing we can do is just grin and bare it.  Masturbation doesn't cut it, especially when the alternative is so much more satisfying.   

I can tell that Zack is just as excited as I am.  He keeps his voice low, even though there's no one around to hear, "So what do you want to do tonight?  Hard, soft, maybe a little roleplay?" he says in an all too suggestive voice.

"I think I'd like to film you working out.' I see his ears flick as he gives me a puzzled look, so I add.  'You know, without your clothes on.  So yeah, tonight is definitely a game night."

"So, you have any ideas this time?  Like maybe you want me to dominate the fuck out of you?"

"Yeah, maybe a little let's just see how it goes," I say.

"Feeling a bit adventurous, are we?' he asked me with a seductive smile.  'Wana watch your little Brother flexing his huge ripped muscles do yeah?" he teases me.

"Haha, of course I do, but I also want to get it on video while you're still young and cute,"  I say as I tease him right back.  We haven't even started yet, and already I'm having fun with him.

"Cute?' he says with an amused snicker.  'You suggesting I might not be cute someday?"

"No, no, of course not, little Bro.  It's just there's a big difference between being cute and being handsome."

"Haha, nice recovery,' he says with a pause.  "Man, I'm so pent up right now.  I want to fuck you so badly.  I can't wait until we're out on our own.  If we had our own place, I'd fuck you right here on the driveway, and I wouldn't care."

"Calm down, Bro; we'll get there eventually."

"Yeah, yeah, I know it's just masturbation doesn't cut it.  I can't stand sleeping alone, plus your body heat is so soothing it puts me right to sleep."

I sigh and say.  "Yeah, but it could be worse.  Mom could be unemployed and home all the time; imagine that."

His lips pull back in a snarl as he says, "Yeah, that's true."

"Plus, I want to watch you go through your growth spurt.  You know what.  I just had a great idea; let's fuck in the basement.  We've never done that before,' I say with a pause as I remember something important.  'Oh, and I almost forgot.  My credit limit resets today, so I can order those cameras you suggested.  You know, the tiny ones you can attach to your head."

"Damn, Alex, you're the best Brother ever.  I want to squeeze you so bad."

"You need to stop squeezing the shit out of me.  One of these days, you're going to break my ribs," I say, unable to stop my fangs from showing as I tease him.

"Hopefully, I don't break your ribs.  I can't make any promises; after all, I am 10 times stronger than you are," he teases me as he leads the way up the driveway.

"You're maybe 4 times stronger than me at most," I say as I follow behind his adorable tail.

He turns to me and says, "I'll race you to the house!"

I get a "what" out of my mouth as he sprints up the long driveway.  I take after him.  He would have beaten me even if I had a head start.  I catch up and follow his bushy black tail into the garage.

"Haha, slowpoke, I win.  And I'm way faster than you, too!' he says confidently as he turns to show me the proof.

My goofy Brother dances in place for a moment.  Clawed toes flex as huge wolf feet bounce up and down.  His muscular calves contort with his movements as he puts pressure on his pads.  I watch as my overly muscled younger Brother sticks a leg out in front of him.  He hikes the bottom of his shorts up to his crotch.  He shakes his muscular leg at me like a show-offy teenager.  Then he snaps the muscles taunt.  Black fur pushes outwards while the rest sinks in deeply between the strands of muscles in his thigh.  He relaxes and flexes again.  He turns his canine leg from side to side to impress his best friend.  He makes a show of dragging his clawed toes across the concrete floor.

My little Brother whispers, 'And this is why I'm faster than you, Alex.  Just look at all those huge ripped muscles,' he says boastfully as he slaps his leg.  'And I know you like it."          
He's right; I do like it.  Our Mother should be asleep, but I keep my voice to a whisper just in case.  "Yeah, yeah, I know.  My little Bro is bigger and stronger than me, and apparently, he's faster, too,' I say with pride.  'And Bro, you're smart as fuck too, but I think I may have you beat in that department by just a tiny amount."

Zack lets his shorts fall back into place.  He rises up on his toes as he stretches.  "Yeah, I'll definitely give yea that one, Alex.  You definitely got the A+ smarts, while I have the basic A-level smarts.  Oh, and you can't forget I'm gaining weight faster than you.  Now I have at least 60 pounds on you."

"Yeah, yeah, I know.  My cute little Bro is 180 pounds of muscle, I remember.  But you must admit that I am keeping up with you," I say as I give into his teasing.

"Actually, as of last week, I'm up to 182,' he says boastfully.  'You know, Alex, I have a feeling that this year I'm going to grow so much that I'll finally become twice your size."

"Well, I hate to burst your bubble, but that will take at least a few more years.  For now, let's just enjoy the fact that I can still get my arms around you."

He laughs at that, and I hear beeping as Zack types in the code on the keyless lock.  I follow behind his bushy tail as we enter the house.  As mature as we are, it's still fun to act like stupid pups, if only for a moment.

The joy on our faces quickly disappears as we walk into the house.  Our Mother is sleeping for her job on the night shift.  It's been our existence for as long as we can remember.  As we always do, and without making a sound, we dawn our workout clothes and head into the kitchen.  We take our supplements and the new ones I added to our regiment and quietly sneak into the basement.   

I can see the excited expression on my Brother's face as we get started.  The new school year has just begun.  I kept my promise to be his personal trainer.  Next week neither of us will have the time to take our time.  We both do a warm-up round with lighter weights before moving on to the heavy stuff.  I spot him and keep a watchful eye on his form.  I can whisper, but even that's pushing it; mostly, I just tap the bar to keep him going.

I've done what I can for today.  My body feels like it's on fire, but I love it.  I know my Brother all too well; at most, he's only lukewarm.  I lean in and give him a lick on his lips, and whisper, "I gotta get started on my homework."  He grabs my shirt and pulls me closer, and licks me back.
We both smile as we feel the impact of our old routine setting in again.

I hear the sound of an alarm clock going off.  Our Mother doesn't like getting up either; we must have gotten that from her.  Just like she's done a thousand times before, she goes through her routine just like us.  I hear her shuffle into the bathroom, followed by the shower a minute later.
I start up the coffee pot and put her lunch together.  She sticks her head into my room and says, "Alright, Alex, I'm off to work.  Tell your Brother I love him for me, okay."
I just nod and say, "Alright, I will.  Have a good night at work."

I watch as her car turns onto the main road.  She's not the worst Mother in the world, that much I know.  Compared to some of the stories I've heard from school, I feel fortunate.  Brent is just one example of that.  His parents are awful.  For all of her faults, at least she's not outright abusive.  Although she knows better than to hit either one of us.  

Our Mother has light grey fur and blue eyes.  We look nothing like her.  I know my Brother, and I take after our father.  She used to remind us of that fact constantly when we were younger.  I don't know exactly what happened between them.  I don't trust her.  I stopped believing her stories a long time ago.  She's never even let us see a picture of him.  Whatever it was, it must have been horrible because we'd never met him, never even gotten so much as a card from him.  She's still collecting his money, so we know he's still alive.

I sigh as I remove my shirt.  I'll be glad when we're out on our own.  I drop my shorts and toss them onto my bed.  I can finish the rest of my homework later.  The new camera is Zack's, but I know where he hid it.  I feel my excitement building as I retrieve it from his room.  I don't soften my footsteps as I head downstairs.

The only good thing about our Mother's schedule is that it leaves us unattended for at least 13 hours.  This is what I love about living with my Brother.  Being with him is all that I want.  I want it rough tonight, and I know he's in the mood for it too, but I want to have some fun with him first.  He enjoys making it last for hours just as much as I do.  Playing with him and stroking his ego is so much fun.  My Brother is the only one I can play these games with and not die from embarrassment.  Having someone you can trust this much is what makes life worth living.

I want to top what I did last time.  Zack has already removed his clothes.  I take out the camera and begin another bonding session.  Zack is lying on his back, working his chest.  He stops mid-lift and gives me a curious look as I pose in front of him with the camera.  I turn my back to him so he'll be in the shot.  I hold the camera out like I'm taking a selfie.  I'm not an actor, but I want to give it a try; plus, I know it will embarrass him. 

I give an excited wave to the camera.  I try and act sexy as I run my hand through my fur, "Hey, future me.  If you're watching this, give your little Bro a boop on his snoot for me.'

I turn the camera around to see the annoyed look on my Brother's face.  'Come on, Zack, I didn't give you permission to take a break.  I want to document that sexy body of yours in action while you're still a cute muscly teenager.'

I take the camera and get closer.  I don't know why I didn't think of this sooner.  I kneel alongside my Brother so the camera will capture everything at his level.

'Alright, big boy, back to work.  Those beautiful muscles aren't going to get any bigger if you just lay there.'

I see the look on my Brother's face as he figures out what I'm playing at.  I hear him breathe in as the bar ascends upwards.  I don't interrupt while he does a few reps.  I keep the shot focused on his chest, where all the action is.  I just hope he plays along.

'You know, I don't think I've ever said this on record, but I guess now is as good a time as any.  It's almost too hard for me to believe how big and sexy my little Bro is.  But here he is.  Can you believe he's only 15 years old?  Look at how big those muscles are.' I say as I pass the camera up and down his body.        

I put the camera on his belly as he works his chest.  'Holy fuck, my little Bro's muscles are huge.  I almost can't believe I'm saying this, but god damn, I love his overly muscled chest.  And whoever is watching this, just look at those thick shapely pecs, and he's only 15!"

Zack stops and sits up.  I sit back and record him flexing his chest for the camera as he says.  "Yeah, and future me look at these pecs.  I know you're bigger than me, but don't forget how big you were when you were only 15.  And future me, I want you to get on top of your Bro.  I want you to pin him down and lick him until he begs you to stop."

I start to snicker as he says that.  I know that's exactly what he'll do whenever we replay this video.

It's Wednesday night, so we have the time.  I wish I had more than one camera.  I film my Brother working his arms as though I'm filming a documentary which, in a way, I am.  I stroke his ego with my commentary as I try and embarrass him.  I play along.  I tell him how big his arms are.  He proves to the viewer that he's bigger and has more muscle than me.

I film Zack going through his routine.  I comment on his powerful male shoulders and his cute lumpy belly.  I try and capture his legs from multiple angles as his muscles contort from the strain.    

"God, Zack, I'm sure glad we like each other."

My Bro gets up from the bench, gets his hands under my armpits, and lifts me off my feet.  He lifts me up and down to show off his strength.  I keep the camera steady as I hold it above my head.  He lets my feet hit the floor but only for a second.  In the next second, I find myself on my back, and he's sitting on my hips. 

Zack takes the camera from me, and I let him.  He points it downwards, saying, "And you're right; it's a good thing I like you, Alex.  Imagine if I was a bully.  I'm the younger Brother, and I'm almost twice your size.  Your life would be a living hell.  I'd beat you every day, and there's nothing you could do to stop me.  And don't think I would stop having sex with you even if you said no."

I hear what my overly muscled little Brother just said and find myself being turned on by the idea of him forcing himself on me.  "Well, it wouldn't be rape if I wanted it," I add.
Zack sets the camera on the rubber mat and leans forward.  I can feel his breath against my whiskers as he says, "I know, but let's face it, I could totally rape you if I wanted to, and there's nothing you could do to stop me."

I run my hand through the fur on his muscular neck as I say.  "You know, that might make for a fun video someday.  We'd need to work on our acting, but I think we could totally pull it off!"

"What?  I wasn't suggesting we actually do that," Zack says, sounding defensive.

I lean forward and lick the end of his nose.  "We could do it in the abandoned house.  I have some old clothes you could tear to shreds.  We could pretend like you abducted me or something."

"You're serious, aren't you?" he asks me.

"Sure, it'd be fun.  And we'd get to see the scary side of that strength of yours."

"Well, maybe someday.  But for today, I think I need to feel you inside me," he says.

I don't argue with him as I grab the back of his head.  He doesn't resist as I pull him close.  I lick his lips, and he lets me inside.  His tongue is bigger and more powerful than mine, and I can feel it.  My tongue slides along his sharp teeth.  I find his fangs as he forces his way inside my jaws.  He hits the back of my throat, and we twist our jaws together.  He pushed his thick tongue down my throat.  I couldn't stop him even if I wanted to.  He lets me choke on it before pulling it back and returning to choke me again.

"God, I love how big you are,' I say, half for myself and half for the camera.  I love this view.  My Brother puts his hands alongside my shoulders.  I know what he's doing.  I know what he wants to hear.  'And I love it when you get on top of me and show off.  I can feel your power as a male, and I love it.  I love your big muscly body, especially your perfect pecs."

Zack chuckles above my head.  I may have indulged him a bit too much.  He gets to his feet and offers me his hand.  I take it, and he effortlessly hanks me to my feet.  I retrieve the camera as Zack wraps his arms around me.  We sway back and forth as we enjoy our bonding session.

"You know Alex, sometimes you are way too goofy for a 17-year-old, you embarrass the hell out of me, and I love it.  You always know how to make me feel better.  You're the best Brother ever," says the big wolf as he snuggles with me.

"And don't forget I'm your mate," I say with confidence.

"Haha yeah, and you're the best sexual partner ever.  And speaking of sex, would you mind if I sucked your cock tonight?"

"Feeling a little hungry, are we?" I tease him.
"Yeah, for some reason, I just really want to taste your cum on my tongue."

"Alright, but I want you to fuck me so hard I walk funny, okay."

"Yeah, I can do that,' my Brother says.

I continue to record as Zack lets go of me and gets on his knees.  His hands flow up my thighs and meet between my legs.  His nose presses under my balls, and he sniffs.  The slightest touch is all that it takes to make me engorge.  He licks at my growing erection.  I'm 17 now, and I'm still growing, and that includes what I have between my legs.  It doesn't seem like much, but my penis has grown by half an inch.

Zack licks at my lengthening cock.  He takes his time playing with my knot before he licks at the tip.  The stimulation makes me rock hard.  I moan for the camera.  My cock disappears into his jaws, and he starts to suck on it.   Strong hands grab hold and squeeze my ass.  His head bobs back and forth.  He knows my body just as well as I know his.  Tonight is about having fun, not quickly riding ourselves of excess seed.

Zack lets my pleasure build.  Pre leaks out of me, but he maintains the pace.  I moan to let him know how good of a job he's doing.  He picks up the pace.  My first orgasm is about to hit me, and he senses it, too.  He squeezes my rear hard as I fire my first shot into his mouth.  I fill his mouth over and over.  I hear him swallow.  He keeps sucking at my cock, wanting more.  I'm drained, but he doesn't stop.  He licks at the sensitive tip and is rewarded with a few more squirts.  I'm spent, and he knows it.  He squeezes my cock to get the last drop out of me.

Zack licks me clean.  I've never seen him so eager to swallow my load before.  He gets to his feet, and I know what he's going to do.  He leans in, and we lock our jaws together.  His tongue is covered with my semen, and he shares it with me.

My Brother licks his lips as he says, 'You know, Alex, I didn't at first, but now I really love the taste of your cum."

"Oh, you do, do you?" I say teasingly.

"Yeah, I love feeling your cock pulsing in my mouth.  The force of your ejaculations against the back of my throat.  Your hot cream filling up my mouth, and I absolutely love swallowing your thick creamy milk.  You're so dirty and so much fun I love it.  I love being mated to you, Bro."

"You know, I think I'm starting to rub off on you.  You're getting to be just as bad as I am," I say with a snicker.

"Well, you are the best teacher.  So you ready to get fucked by your overly muscled little Brother?" he says.

"Fuck yeah, I am."
I forgot the lube, and most importantly, I forgot his bit guard and the rubber sheaths for his claws.  I give Zack the camera, and he waits while I retrieve them from my bedroom.  He films me while I slide the covers over his claws.

Zack is already hard.  I squirt lube onto the tip of his canine cock as I say.  "God damn, Bro, your hormones are turning you into a beast.  Your penis is getting just as big as your muscles.  I'm so lucky to have you as a brother."

He laughs and says.  "Yeah, and to think I'm younger than you."

I set the camera on a bench.  I wish I had a dozen more.  My Brother picks me up.  I wrap my legs around his waist, and we lock our jaws together.  I can still taste my cum inside his mouth.  He pulls my cheeks apart and presses the tip of his cock against my hole.  He pushes it in and pulls it back out, only to push it back in again.  He knows how much I like it when he penetrates me.  I tose my head back and moan as he penetrates me again.

"Damn, Zack, you really know how to spoil me, don't you?"

"Haha, I know how much you like it when I penetrate you with my giant cock."

"You know I think I'm doing too good of a job teaching you."

I can feel my Brother's strength as he starts to thrust into me for real.  I wish I had a camera to capture the action from every vantage point.  He sets me down, and we make use of the exercise equipment.  I lay my chest on a bench, and he gets behind me.  He mounts me like a wolf.  Zack holds back enough to keep from ramming his knot inside me.  The sound of metal banging against metal fills the room.  I lay there and enjoyed the sensation of my Brother thrusting into my guts like a wild animal.  It's nice letting him go crazy with the bench doing the hard work of holding me up.

We go around the room, fucking on one piece of equipment after another.  I lay my chest on another bench.  Zack gets on top of me and penetrates me up to his knot.  He makes me howl.  He lays his full weight across my back as he ties with me.  We both enjoy the intermission as his knot expands and locks us together.

Zack licks at my ear and whispers.  "God, I love tying with you, Alex.  And I love feeling your sexy little body beneath me."

"Yeah, I might not be a true bottom, but I do love bottoming for you."

"Yeah, and it's especially fun because I'm almost twice your size."

"Haha yeah, and you know what the best part is?" I ask.

"Actually, I know exactly what the best part is.  It's because I'm committing incest with my big Bro."

"Damn, Zack, you really are as bad as me.  Don't ever change.'

I can feel my Brother's knot expanding and filling my insides.  I wrap my arms around the bench and hold on as he thrusts.  He doesn't hold back.  My fur slides against the bench as he pounds me like a sex toy.  He lays his chest against my back.  His arms wrap around me, and his hands find my forearms.  The rubber sheaths keep his claws from sinking to the bone.  I know my mate all too well.  I know exactly when he's going to bite me.  I feel the bite guard crushing my shoulder as my best friend starts to cum inside me.  I can feel his hot semen filling my bowels.  With each ejaculation, he unclamps his jaws and bites down hard.  He growls as he bites me like an animal.  He thrusts as deep as he can, and I know why.  I can sense it; he's mating with me like I'm a female in heat, and I love it.  

"Harder, Zack, harder, make me cum!" I scream.

He can't say anything with his jaws wrapped around my shoulder, but he complies.  He pounds me so hard I begin to orgasm with him.  It's a good thing he already sucked my balls dry; otherwise, we'd have a hell of a mess to clean up.

I don't know how long he humps me, but I know when he's done.  My Bro collapses on top of me.  My orgasms stopped, but his orgasms continued.  We both realize the bench isn't that comfortable, and he lifts me off.  I grab the camera and take it with me as we lay on the floor together.

Zack rolls onto his side, and I have no choice but to mirror the position.  He wraps himself around me in a fetal position, and we both lay there and enjoy being tied together.

'God damn, Bro, I love feeling you pumping your seed inside me," I say.

"Yeah, and I know why you like it so much."

"Oh, and why's that?" I ask.

"Well, for one, because I can fuck you so hard, I make you orgasm."

"Haha yeah, you're pretty good at that.  And you made me leak a little bit.  Don't worry; it's not that bad," I say.

"Well, at least you didn't spray it all over the ceiling like the first time.  That was such a bitch to clean up."

"Yeah, that was a pain.  Oh, and what's the second reason?" I ask.

"Because I'm your Brother,' he says as he snuggles with me.  'And because we aren't supposed to, that's why.  Fuck I love committing incest with you."

"God damn, Bro, you're so much fun I can't stand it."       

I want to watch the vid we just made, but I still have homework to do.  I smile into the camera and hold it up to get Zack in the shot.  He says hello as he licks at the side of my muzzle.  Zack can't pull out in the basement.  Neither of us wants to clean up that kind of a mess.  It's a good thing he's strong enough to carry me upstairs with his cock still impaled inside my ass.

Zack sets my feet on the tiled floor in the shower.  He hugs me and pulls his enormous cock out of my body with a loud wet pop.  His cock hangs between his legs.  His thick cream pours out of me and onto the floor.  I take a moment to capture his canine penis covered with semen with the camera just before I make a show of licking it clean.                   
 
* * *           

The first three days of school were great, although it was better for me than it was for my little Brother.  He's a freshman now, so everything is new to him.  
				
Zack was in a bit of a fog for the first week.  His friends and mine hit it off from day one.  It would be a bit overwhelming for anyone to get used to a new school, with new people and a new routine to get used to.  Hanging out together at lunch became our new thing.  I wasn't surprised Chris didn't join us, but in a way, I was glad.  It took a while, but eventually, he realized his old friends weren't as lustful with the ladies as he was.  I'd gotten sick of listening to his sex stories.  

I'm sure his stories are only half true.  A year ago, he was only going after his fellow canines.  At the time, he was with a border collie named Britney.  It was followed by a bad breakup.  She scared him half to death when she told him she was pregnant.  It turned out it was all a lie.  It was just her way of getting revenge on him.  He switched to felines after that, only they're all of the smaller domestic types.  They're all from our grade, or so he says.  His favorite thing is to go after the smaller ones, the ones who he says are too small to take him. 

* * *      
				
My friends and my Brother's friends all know how difficult it is for us to get out of the house.  We only see them at school, but it didn't mean they couldn't start to hang out with each other on their own, and that's precisely what happened.  Before we knew it, freshmen and juniors were hanging out together.

Zack and I are enjoying the new school year, although we no longer have much free time.  Before we knew it, the leaves started to change colors.  Soon after that, it began to snow.  We could no longer use our little clubhouse once the ground was a solid sheet of white.  We couldn't risk leaving footprints in the snow.    

As a junior, I have way more homework than Zack does.  When it comes to sex, I've never said no to him.  Unfortunately, when we do have sex, we usually keep it brief.  Zack took working out to a whole new level after I took on the challenge of coaching him.  I did some research, and so did he.  We both added a few more supplements to our regiments.  It was often a choice between a workout or hours of sex.  I didn't blame him for choosing to stick with it.  In truth, it gave me the time I needed to keep up with my studies.

I have to admit that we've made some really erotic sex tapes.  We got a lot of use out of the camera that I gave him for his birthday.  I got several more to cover our sessions from even more angles.  The thumb drive has thousands of pictures on it of both of us.  Not all the pics are nudes.  Some are of us posing together as the 2 person family we are.  The majority are just fun, sexy shots.  The rest are a continuing documentary of our transformation from teenagers to adults.         

* * *

It's a typical Tuesday evening.  I coached Zack through his routine.  I force him to focus on the muscles that he's been neglecting.  Now that I've been giving him extra encouragement, he's become even more obsessed with his body.  It probably didn't help that I told him he should consider becoming a model.  Since then, He's been less focused on building mass and more obsessed with his appearance.        

We take turns.  I'm Zack's coach, and he's mine.  We had to be quiet.  Our Mother doesn't have to work tonight, but she is upstairs.  I leave Zack to finish his workout by himself.  I don't want to, but unfortunately, I have too much homework.

The pads of Zack's feet hit the wooden floor with a loud thud, indicating his growing weight.  He disappears into his room and starts on his homework.  A few hours go by, and our Mother leaves to go 'hang out with her friends,' we both know what it means.  

"Hey Zack, how busy are you?" I say as I drop my laptop on his desk.

"I got a bit more to do.  Why, what's up," he asks me.

"I know she's gone, but this isn't about that.  Don't worry, I'll help you with your homework.  I had to take a personality test for my economics class.  It's to help determine what kind of job I'm best suited for.  You know, like a lawyer, or a cop, or C.E.O., or someone who's destined to work in a factory all her life.  Do you want to give it a try?  I think I know exactly what you are, but I think you'll find it explains a lot."

"Alright," he says.

I give him my laptop, and he starts taking the test.  He finishes and hits the complete button.  A second later, the results pop up on the screen.  It only took him about 20min at most.

| Congratulations, you're personality type is Sigma |
His ears flip, and he frowns at me and says, "What did your's say?"

"The same thing, sigma.  I guess we really are twins, after all."

"Sigma, I've never even heard of it.  It's not alpha or beta, so what is it?"

"Check out the description."

A Sigma male is an introverted alpha male.  Often referred to as the lone wolf.  This personality type accounts for an estimated 3% of the global population, making it the rarest of all personality types.  

Zack continues onto the list of traits.  I can see it on his face as he reads through them.  "Often introverted.  Yeah, a bit, for sure.  A quiet alpha, ahh yeah.  A confident leader.  Highly successful, extremely driven, self-motivated, agree with all of that.  Doesn't care what other people think.  Couldn't agree more.  Emotionally intelligent, ah fuck yeah.  Avoids large crowds.  Has a small number of friends.  Forms strong, long-lasting bonds yep and yep.'

He gets to the bottom and says, 'damn Alex, it really is spot on.  It really does explain a lot.  I've always felt like an alpha, but at the same time, I didn't."

"Well, you're right, except we're just the quiet type of alpha.  But it explains why we're so close and don't have like 20 friends.  And why we aren't fucking our way through the entire student body."

Zack closes the laptop and says, "At least it says we're among the most successful.  We both fit that trait to a T."

I sit on his bed and say, "Being a sigma explains a lot, like why we aren't social butterflies.  I already knew that part was true.  But have you ever thought about fucking one of your friends?'

I watch my Brother half choke at the question as I continue, 'Ahh, come on, Bro, you can tell me.  We're mates now.  It'll be fun.  You know you can tell me anything."

"Okay, but you go first."

"Oh, okay.  Well, I don't really find Brent or Simon that attractive.  Don't get me wrong, it might be fun to try fucking someone smaller than me for a change.  I like both of them, but as far as sex goes, I don't really find them that hot.  I had the hots for Chris for a while.  I used to jerk off to thoughts of him all the time.  Unfortunately, he's a total pussy chaser.  Alright, it's your turn."

"Alright.  I would totally fuck both Vance and Jacob," he says with confidence. 

"Damn, Zack, you say that like you've thought about it.  Gezz Zack.  I mean Vance, I can see, sure.  He's a big ass mountain lion, so he's at least big enough.  But you'd fuck Jacob!  A massive wolf like you fucking a tiny red fox, come on.  He's only like 4 feet tall; you would literally split him in half.  Just an inch of your cock would be enough to rip him bloody."

"You're messing with me, aren't you?' my Brother asked, sounding unsure.

He figured me out, and I can't hide the smile that comes over my face.  'Yeah, you got me."

"Well, don't stop."

I laugh; I get what he's playing at and say, "You know it's a good thing we're mates.  I'd be too embarrassed to say this in front of anyone else."

"Oh, come on, Alex, I know exactly how filthy your mind is.  That's what I love about you.  It's why you're so much fun.  You're my sexy big Brother.  It's just me and you for life, so give it to me."

"Haha, oh, alright, but this is kinda embarrassing to say about our friends.  After all, there's no way in hell you'd be able to get your giant cock inside him, but if you did, your knot would swell so much you'd break his pelvis in two.  And, of course, you'd bite him for real.  I bet you could put so much cum into him you could pop him like a balloon."

"Damn, Alex, you really know how to turn me on, don't you."

December 2nd of last year was the day that changed everything for us; it was the day when the power went out.  I can't believe a year has already gone by.  Zack likes it when I call him my 'Little Bro.'  It's my nickname for him.  It's fun because he's nearly twice my size.

My younger Brother turned 15 a little over 6 months ago.  He behaves like your typical teenager.  He can still be playful sometimes, but he acts more like an adult with each passing day.  We live together, and we're maturing together.  I experience his transformation into an adult, and he experiences mine.  This is why I love growing up with him.  Our bond was strong before, but now it's more than unbreakable.  Being with him is causing my personality to change, and I surrender to it willingly.  Our relationship goes both ways.  He changes for me as easily as I change for him.  It's getting to the point where I can't tell where I end and he begins.  

It's only been a year since we came out to each other as gay.  Sometimes it feels like we're more than twins.  We're finishing each other's thoughts more and more.  I cherish every moment of growing up with him.  I enjoy watching his body change with each passing month.  I'm growing too, but he's growing far faster than I am.  

I wanted my Brother to get bigger, and I wasn't disappointed.  I never would have guessed how much he would have grown in such a short amount of time.  I managed to gain a whopping 2 inches in height over the last year.  On the other hand, Zack grew 4 inches in the same amount of time; he's 6 foot 4 now.  He's so much taller than he was a year ago; he's got 8 inches on me now.  A year ago, my eyes were level with his collarbone, and now it's closer to the middle of his chest.  Most other siblings would be jealous, but not me.  Unlike them, he's my mate.  Unlike them, I want my little Brother to get even bigger.

I doubled down as Zack's coach, and he did the same for me.  I knew I wasn't working out to my full potential, but he helped get me there.  A year ago, I was 90 pounds soaking wet.  I'm proud to say I gained 30 pounds of muscle over the last year.  That was good for me, except Zack gained 50 more pounds of muscle; he weighs 190 now.  

As his coach, I drove him to focus more on his aesthetics.  He likes the idea of looking sexy just as much as I do.  He's fine when it comes to building mass, but smaller muscles here and there get overlooked.  The finer details always need a second pair of eyes.

It's Saturday night, and our Mother is at work.  I can do my homework tomorrow.  Tonight I'd rather spend it with my best friend.  We both shed our clothes once her car is out of sight.  We've become so accustomed to working out together while naked that we don't even notice it anymore. 

The barbells in my Brother's hands are huge.  I scream at him as he strains to push them over his head.  "Come on, Zack, keep going, keep going, keep going!"  

He gets there, and I make him hold it before letting him slowly lower them back down, only to punish him again.  A year ago, his chest was well-muscled, but I didn't have an eye for it back then.  He did a good job with the middle and bottom of his chest but never gave much attention to the top of his pecs.  I can see the difference after just 5 months.  Now his pecs jut outwards dramatically from below his collarbone.  His shirts hang off of his chest now, and I'm not the only one to notice

That wasn't the only thing he had neglected over the years prior.  I had him work on his neck so much that his collars are starting to get a bit tight.  The border between the neck and shoulder is sharper now.  Every strip of muscle in his shoulders stands out on its own.  His biceps were good, but his triceps needed work.  His forearms look like steel pipes welded together.  His veins pop more than before, with a few more branches showing that couldn't be seen a year ago. 
 
I had to force him to focus more on his back.  The V shape keeps getting wider and wider with each passing month, but he has a lot more work to do.  His ass and the back of his legs were challenging to target.  But now I almost start to drool when I see his naked rump.  Seeing his naked ass makes me think about what else those muscles can be used for.               

We punish each other for 3 more hours.  I found it easier to go past my limits when he drove me to it.  It's almost 9pm when we finish.

"Hey, Zack, I can't believe it's been a year since we started having sex."

"Don't you mean incest?" he says teasingly.
I look up at him and grab his hips as I say, "And you know I absolutely love getting fucked by my little Brother.  Only you're not so little anymore, are you?  I can't believe how big you've gotten in just a year.  And I'm really loving all the extra muscle.  And most of all, I can't believe your penis has grown an inch.  And I can definitely feel all of the extra girth that comes with it."

"It's been a while; let's take our time tonight," my Brother begs.

"You know, sometimes I think we really must be twins.  I swear to god, you know exactly what I'm think all the time.  Hopefully, the power won't go out this time.'

I bought 3 more cameras and 2 small GoPros as well.  The GoPros we strap to our heads to give us a first-person perspective.  We've gotten pretty good at editing our films.  Only tonight isn't a night for making another film.

'You know I've wanted to do this with you for a while.  I don't know why we haven't done it already.  Let's fuck in the shower," I say.

"Shower sex.  I've been wanting to give that a try," says Zack.

We're doing things a bit in reverse.  Usually, the shower and clean-up come last.  I grab the bottle of lube, the special shampoo, his bite guard, and the rubber sheaths for his claws.  I hear the shower come on, and I join my overly muscled teenage Brother under the hot water.  Water soaks into his black fur and reveals even more of his masculine curves.  I put my ass on the tile floor, and he gets down on his hunches.  He spreads his legs wide and lets me watch as his penis forces its way out of his sheath.  He has 13 inches now, which means he drives it an inch deeper into me than he did a year ago.  

The enclosed space is steaming hot.  Zack adjusts the sprayer and sets it to mist.  There's little room in the shower; the space is tight.  It's probably why we've never done it in the shower before.  We can't lie down, but we can enjoy plenty of other positions.

He lets me enjoy the sight of his increasingly more aesthetic body.  It might be vain to dwell so much on appearances, but you can't argue with his animal magnetism.  His legs remind me why I love muscular guys so much.  Muscles that were underdeveloped are now making themselves seen.  The lines and shapes of many different muscles flow in a functional direction.  It's so visually complex it's impossible to take in at a glance.  It's all the more enticing knowing he's only a teenager and that he's still growing.  

My Brother rises to his feet and braces himself against the shower walls.  He offers me a foot.  It's huge, nearly as big as both of mine put together.  I spread his canine toes apart and worked my fingers into his pads.  I get a soft moan out of him.  

"Ahh fuck Alex, you don't know how good that feels.  It's been so long  since you touched my feet."

"Here, sit down," I say.

Tonight is our night to enjoy each other's company and our bodies and to love each other.  He complies, and we each put our backs against a wall.  He gives me his foot again.  I spread his toes apart and bend them back until the joint cracks.  I crack them one after the other.  The pads of his feet are as rough as sandpaper, like they should be.  I kneed the pads of his feet, and he looked like he was melting from the sensation.  He gives me his other foot, and I do it all over again.  

"Here, let me do you," he says.

I put my foot on his lap.  It's been a while since he touched my feet.  I know how good it feels.  He forces his fingers between my toes, and the breath goes out of me.  

"Holy shit, that feels so good," I say.

He cracks my joints like I did for him.  He massages my pads.  It feels so good I could almost cum.  He finishes with my other foot.  I won't forget this.  I'll include this when we have the time for it.

I get up from the tiled floor and climb onto his lap.  I press my chest against his.  I wrap my legs around his sides.  Our cocks press together.  I wrap my arms around his neck, and we kiss.  His strong arms wrap around me.  I pet him like a wolf and play with his long ears as I wrestle with his tongue.  

I pull away.  My Brother looks me in my eyes, and he says, "You know there's no reason for me to fuck anyone else, right?"

"I know, but it's always good to share our thoughts with each other."

"I'm not sure if I even want to.  At least not now.  Now that we're together."

"Not even a threesome?" I ask jokingly.

I get him to laugh at that, and he starts to lick excitedly at the side of my face.  I return the gesture.  I drop my muzzle to his shoulder, and he drops his onto mine.  We've never had sex in the shower before.  Both of us just want to feel wet fur against wet fur.  We hug and hold each other while the hot mist washes over us.  

Zack's hands start to slide up and down my back.  I don't have mass like he does, but he still enjoys feeling me up.  

"You know, Alex, I don't say this much, but you're really starting to put on a lot of muscle too."

"Well, don't worry, I don't plan to put on too much.  I love this dynamic we got going.  You, the macho alpha, and me, the half-size sigma.  Just out of curiosity, how big do you want me to get?  Because I'll stop whenever you tell me to"

I get him to laugh.  He gives me an affectionate squeeze and says.  "I don't know for sure.  Just as long as your build is less than mine."

"God, I love your honesty.  You're my little Brother and holy fuck, I love that you're bigger than me.  I definitely don't want to ruin it.  But at least let me get big enough to withstand you.  You're starting to get so strong I can barely keep myself upright when you mount me.  Your thrust are so powerful I can barely keep you from knocking me over."

"Well, it's probably good that I'm focusing more on my aesthetics and less on mass."

"Ahh yeah."

It doesn't happen often, but with my fur being wet and slicked down, I figured now was a great time to remind him that I am pretty muscular.  I leave him on the warm wet floor and show him my legs.  I hold a leg out for him and flex.  His fingertips slide between each strand of muscle.  I turn around and give him a complete picture.  I give him a good look at my cute wet ass.  I flex my back.  I reach one hand towards the ceiling and show off my bony ribs.  I've always had a 10-pack.  Only over the course of the last year it becomes less flat and more like rows of rounded hills.  I show off my chest.  I dance my pecs at him.  I'm not as masculine as he is, but it's always good to remind him that his mate isn't at all weak.

We caress each other's bodies as only two gay brothers who love each other can.  Zack covers my cock with lube.  My Brother puts his hands against the tiled walls and braces himself.  He squats down just low enough for me to reach his tail.  I tug on it and push my pointed tip against his hole.  We've done this so many times before it slides in with ease.  I wrap my arms around him, press my knot against his hole, and hold it there.  I listen to his soft moans.  

I rub my muzzle against his back, saying, "You know, I can't believe we've been having sex for a year now."

"I know, right,' he says with a pause.  'And you know Alex, I really do love feeling you inside me, don't you.  I hope you don't think that you're not big enough to please me because you are.  I like you just the way you are."

"I'm your Brother, I know.  You don't need to worry.  I know who I am.  I know who you are.  And I'm glad I'm not the older Brother who's a supper alpha with an 18-inch cock.  I don't think you would like it too much if I was strong enough to take you by force."

He laughs, and I slowly thrust, eliciting a few more moans from his throat.  

"Let's try a new position," my Brother says.

I pull out and say, "Okay."
He gets low.  He puts his chest on the floor and lifts his rump into the air.  I get the idea.  I climb onto him and mirror his position.  I push him lower so that I can keep my feet on the floor.  My chest is low, and my rump is above me.  I reinsert my cock, and he moans.  I give him a few thrusts just to test it out.

Zack straightens his legs, and my feet leave the floor.  Gravity wants to pull me inside him.  I don't resist, and my knot pops in with ease.  I let him enjoy the sensation of my knot expanding inside him, locking us together.  Zack has the strength to hold me up.  I thrust, and he grunts.  I let him feel my strength, and he doesn't even quiver.  This is what I love about him; it's like I'm fucking a mountain of muscle.

I start to cum inside my younger Brother.  It's minutes later before I finish with the initial load.  He knows when I'm done.  There's no room for us to stretch out.  Zack curls into a fetal position, and I copy it from behind.  I wrap an arm around his ribs, and he holds my hand while we both enjoy the continued sensation of being tied.

Hot mist falls upon us from above.  I love tying with my Brother.  This is why I love having a knot.  My orgasms are milder, but they continue.  I give him a jab every once in a while to let him know I'm still cumming.

I feel myself getting soft.  I pull out.  Zack rolls over and says.  "You ready for me to fuck you so hard your feet don't touch the floor?"
