Filling My Brother
Chapter 4
By WaffleSquadron

“Yeah, suck my dick.  You like that, don’t you?  You like sucking my big cock.  I’m gonna shove it down your throat, and make you choke on it!”

With that Cody grabbed onto my head with both hands, and humped his pussy even harder against my mouth.  I pushed my tongue between his folds and licked all around the little pocket that held his clit.  At the same time I pushed my finger into the soft heat of his vagina, as far as it would go.  Cody moaned even louder than before, and arched his back in ecstasy.  It was Saturday, and we were alone, so there was no need for him to hold back.

“Oh fuck, I’m gonna cum.  Do it, suck me off”

I stopped for a moment, and removed my digit, before taking my middle finger and putting it up against his spade as well.  Then, quickly, I shoved both of them inside, filling his pussy even more.  I pulled my tongue back, placed my lips up against his clitoris, and gave it a gentle suction.  Cody went wild.  His hips started to piston into my face a few times, and then he just ground his spade back and forth into my mouth.  

“Ahhh! Fuck! Take it! Take my cum! Swallow it all!” he yelled into the empty apartment.

His pussy clamped down hard, and I felt the walls start to spasm around my invading fingers.  He grabbed onto my head so hard I was afraid he was going to pull some fur out.  I felt him tremble and throb for a good while before it seemed like all the energy drained out of his body, and he went limp.  The two fingers I had inside might have been the only thing holding him up at that point.  I slowly untangled myself from Cody, while still trying to keep him upright.  I stood, sneaking a quick kiss on his lips in the process, and he finally responded by wrapping his arms around my neck in a loose hug.  

“You ok buddy?  That was a little extreme, even for you,” I asked.

“Mmm I’m fine.  Thanks Kyle, you’re a really good cocksucker,” he teased.

“You’ve got a dirty mouth for an eleven year old, you know that?”

“Ha! Look who's talking, your mouth smells like pussy.”

I pulled away from his embrace, feigning a scandalized look, and smacked his bottom towards the living room couch.  Cody squealed and ran off.  I couldn’t keep my smile contained.  The past three months felt like one long dream.  Ever since our heart to heart talk, and then knotting for the first time afterwards, the two of us were closer than ever.  Every time I looked at the boy I wanted to kiss him, and every time we were alone, I did.  

Cody was different too.  It used to take a little prodding, or cajoling, or sometimes just plain begging, to get him in the mood for sex.  Now he was practically insatiable.  I woke up on more than one occasion to him riding my cock like we were in a rodeo.  Once in a while I even found myself needing to be the voice of reason, stopping before things got out of hand; like when Cody wanted to fuck while mom was down the hall making dinner.  Some stuff was just too risky.

“Wow, rude.  And after I was so nice to you!” I shot back

“Oh yeah?  What are you going to do, punish me?” Cody asked seductively.

I cocked my head a little at that.  I just licked him to a screaming orgasm, and the kid was already angling for more.  Cody’s newfound sex drive would have been alarming; if it weren’t for the fact that I was just as horny as he was all the time.

“Yeah, I am.  You deserve to be punished, you little punk.”

“What are you gonna do?  You want to spank me?  You want to spank your poor, innocent little brother?” Cody asked, his voice getting low and husky.

“No, you'd probably enjoy that, you little pervert.  I’m going to bend you over this couch, and fuck you until you can’t see straight,” I responded.

His eyes lit up at the prospect of even more sex, and I once again began to wonder what kind of maniac I’d created.  I grabbed him by the scruff of the neck, not hard enough to hurt or anything, and pushed him up against the arm of the sofa.  Cody draped his body over the side, and lifted his tail straight into the air.  He looked back with a hungry expression, and wiggled his tan furred bottom a little in my direction.

I grabbed his tail and held it even higher, and with my free hand I started to rub the lips of his pussy once again.  I didn’t waste more than a few seconds getting him ready.  The boy was already soaking wet, and if anything I would just be teasing myself.  I simply lined my sheath up with his spade and pushed.  Cody let out a gasp, followed by a long groan.  I sank all the way inside with a single long thrust, and took a few moments to feel those tight walls twitching around my cock.  My knot was fully inflated in a few seconds; locking us together, and stimulating him even more.  After quite a bit of experimenting we’d figured out that when we tied, I was actually rubbing against his clitoris from the inside.  I pulled my hips back until his puffy outer lips were stretched taut around it, nearly becoming a perfect circle.  Cody let out a shuddering groan, and tightened up even more around my cock.

“F-fuck that's so good.  You feel so huge inside me.”

That was always a nice boost to the ego, and I responded by slamming forward hard enough that Cody stood on his tippy-toes.  Letting go of his tail and locking my paws around his hips, I kept my cock pushed forward and started to grind against his rear in tight little circles.  He started whimpering with pleasure, and the cocky little boy that had been teasing me just a minute ago was replaced by a submissive little puppy.  I felt a weird sense of pride swell up in my chest that I was driving Cody to an incoherent mess of sexual bliss with just my knot.  My cock was begging for release, though, and I could only hold off for a minute before starting to fuck for real.  Those cute little whimpers turned into moans, and that sounded like music to my ears.  The mood was different than before, and I took full advantage of this change in dominance.

While still thrusting, I leaned down over his back and spoke directly into Cody’s ear, “You like that don’t you?  You like having big brother fuck your tight little pussy.”

“Kyle, don’t…” he whined.

I knew he didn’t like talking about his girl parts when we were together, but I had a plan.

“You’re my little boy, and I’m going to fuck you whenever I want.”

I actually felt him shiver when I called him my boy, and that was exactly what I wanted.

“Say it.  Say that you’re my little boy.”

We were still fucking the whole time, and Cody was whining and pushing back against me with every thrust.  

“Ahhhh! I… I’m your little boy!” he cried out.

His pussy squeezed down really hard as those words left his muzzle, and another thrill of dominance shot up my spine.  I started kissing the back of his neck, and throwing more of my weight behind every hump.  I could feel the tension in his body rising with every move we made together, and it was time to deploy my secret weapon.  

I licked behind his ears, and then spoke directly to Cody again, “You’re my little boy, and I’m gonna fuck your little boy pussy.  I’m gonna fuck you, and fill you up with my seed.”

Then, in true canine fashion, I bared my fangs and took the scruff of his neck between my teeth.  Not enough to actually break the skin, or even hurt, but more than enough to let him feel it.  Cody’s back arched upwards like he was being shocked by electricity, and his entire body froze in that position.  I bucked into his rear one last time, and buried my cock as far inside him as I could.  Then, taking a paw away from his hip, I reached around and started to rub his clit through the lips of his spade.  Cody’s moaning became even louder, and took on a slightly deeper pitch.

I felt myself slip over the edge, and my knot somehow became even larger, before I started unloading deep inside my little brother’s pussy.  I growled into the back of his neck as I felt the pulsing ecstasy of my orgasm tear through my entire being.  I actually felt my sperm splashing against his inner walls and filling up his body.  There was only one thing that could have made it better, and a moment later it happened.  Cody squeezed down around my cock so hard I actually stopped squirting for a second, before his pussy began to throb and ripple against me.  His moans were now just screams of total sexual bliss, and we were joined together in an awesome experience of total intimacy.  We had no secrets or shame, we only had each other and the love we shared.

Our orgasm lasted so long.  It was beautiful, and thrilling, and absolutely exhausting.  When it eventually began to fade down to a dull buzz of pleasure, I found myself laying across Cody’s back, still grasping his scruff in my muzzle.  I slowly, and carefully, began to lift myself back into some semblance of a standing position, but Cody was still just collapsed face down.  At some point during our lovemaking I must have actually fucked him up over the arm of the sofa, and it looked like he was in no hurry to move.  Deciding to just go with it, I pushed the two of us fully onto the couch together, with me spooning behind him.  We were laying on our sides, and I gently draped an arm around his belly.  My orgasm was still smoldering; my cock throbbing every few seconds and squirting a little bit more into Cody.  I just kissed the side of his face, and rode those waves of climax.

“Mmmm Kyle… Ohh that was the best one yet,” Cody said, finally stirring.  

He turned his head enough that we could kiss a little more directly, but otherwise was content to lay in my arms and savor the afterglow.  Eventually the twinges of orgasm slowed down, and my mind was finally clear enough to think straight.  I whispered a few sweet words of love, but I still needed to make sure he was fine.

“Was that ok?  I didn’t bite too hard or anything, right?  I just suddenly felt like I had to claim you.”

“No, that was… perfect.  I love you so much Kyle.”

I kissed him once more, and answered, “I love you too Dakota.”

I rubbed his belly a little, and couldn’t help but notice he felt a little chubby.  Not that I was going to bring that up; nothing would ruin the moment quite like calling him fat right after we made love.  Besides, I knew some boys tended to put on a little weight around his age.  Cody groaned quietly at the attention, and cuddled backwards into me a little more.

“I love when you cum inside me.  Your sperm feels all warm and gooey in my belly when we are tied like this.”

God it was hot hearing him talk like that, and I felt my next squirt come out just a little harder.  We just laid there, tied together, for a good long while.  Eventually Cody got bored, and started rooting around until he found the remote control, and turned on the TV.  I was still twitching and cumming, and was perfectly content to just lay there for however long it took to finish.

A few minutes passed, and Cody asked, “So what's for lunch?”

“Hmm? Wha?  Oh, umm, I think we have some peanut butter.  I’ll make sandwiches later”

“Do we have any pickles?” he added.

Now that got my attention.  I actually sat up a bit, and gave him a questioning look.

“What? You hate pickles.”

“Yeah I know, but I dunno, I just really feel like eating them for some reason…”

I didn’t give it too much more thought, and simply said, “Alright whatever.  I’ll see if we have any.”

A few more minutes passed, and I felt my knot deflate enough that we could separate.  With a firm tug my cock popped free, and Cody cupped a paw around his spade to hold in all the cum.  I had actually planned ahead for once, and had some paper towels stashed nearby.  Cody pressed them to his pussy, and waddled towards the bathroom, while I snickered at him quietly.  I cleaned myself up a little, and then got started on lunch.  I wasn’t exactly a gourmet, but I could still put together a peanut butter and jelly sandwich.  As I opened the fridge to put the jelly away, when I remembered Cody’s earlier request.  We actually had a jar of sliced pickles, so I shook my head once again, and set them out on the table.

Ten minutes later a still naked eleven year old pup came strolling into the kitchen, and plopped himself down at the table.  He practically inhaled his sandwich, and didn’t even look up until the last crumb was gone.  I watched as his eyes widened in surprise upon seeing the pickle jar.  Without even missing a beat, he opened the lid and began devouring slice after slice.  I couldn’t believe what I was seeing, but Cody ate like it was his favorite food.  Then, after taking his fill, looked up at my plate.

“You going to eat that?” he said pointing to my remaining half a sandwich.

I wasn’t really hungry, and he was obviously starving, so I just pushed it across the table to him.  Cody ate that down in a flash, just like the first one, before leaning back in his chair, seemingly satisfied for the time being.

“Ahhh that hit the spot.  Thanks Kyle,” he said, adding a small burp for emphasis.

I cocked an eyebrow, and asked, “How were you that hungry?  Didn’t you eat breakfast?”

His ear flattened a bit and he suddenly looked a little sheepish, “No… I threw up this morning, and I didn’t feel like eating…”

“What!  Why didn’t you say something?  Are you sick?  I can call mom, and go pick up some medicine at the pharmacy,” I said, very concerned.

“No, no it’s nothing.  I feel fine now, it just sorta happens.”

“Wait, what do you mean it ‘happens’?  This isn’t the first time?”

“Well no… I threw up a few days ago too, and maybe a couple times before that… But it's not a big deal ok, I feel fine for the rest of the day.  Don’t worry about it.”

“Cody that’s still not good!”

“Can we just talk about something else?  I promise I don’t feel sick at all now, ok.”

I grimaced at his stubbornness, but it was pretty obvious I wasn’t getting anything else out of him for a little while.  I nodded, and let it go for the moment.  I was still worried, but Cody simply smiled and slipped back into the livingroom to watch cartoons.  I wasn’t going to be deterred quite so easily, however.  I cleaned up the table, and grabbed the family tablet computer off a nearby shelf.  It wasn’t even close to a new model.  We’d had it for a few years already, and it wasn’t state-of-the-art when we got it.  But it could still connect to the internet, and that was all I needed at the moment.  Our dad had set up the apartment wifi with all kinds of ironclad parental filters, but what he didn’t know is the coffee shop down the street had an open router.  The signal reached just far enough that we could connect to it in our bedroom.  I walked down the hall, threw on some clothes, and plopped down on the bed ready to begin my search.  I knew how to use private browsing, and began to search the web for Cody’s mysterious symptoms.  

As it turns out, searching for “morning sickness” and “weird food cravings” only brings up one type of result: “early signs of pregnancy”.  At first I was just frustrated.  That obviously didn’t apply to Cody.  I kept rephrasing my search, or changing the word order, or anything to get to the information I was actually looking for.  After ten minutes of dead ends, a sudden dread began to grip my heart.  I kept at it a little longer, with no more luck, and had the creeping realization that this might be exactly the answer I was after.  

It seemed completely nonsensical at first.  Cody was a boy, and boys do not get pregnant.  But he had exactly the same parts that girls used to make babies; I had spent enough time inside him to know that.  I started clicking on links, and reading the actual information, which did absolutely nothing to allay my fears.  Cody had a vagina, which led to the logical conclusion that he might also have a womb.  And if that were the case, there really wasn't any reason he couldn’t become pregnant.  Neither of us had even considered the possibility that we might be doing something incredibly unsafe.  I started breathing in quick huffs as the sheer magnitude of this sudden revelation became apparent.

Oh no. Oh fuck.  What if I got him pregnant?  What were we going to do?  Our parents would absolutely kill me if they found out I was having sex with Cody, let alone put a puppy inside him.  We were so young, how are we going to take care of our own cub?  Wait, Cody is only eleven, that's too young to get pregnant, isn’t it?  I started to calm down a little at that thought.  Girls couldn't get pregnant until they were older, and as far as I knew Cody was nowhere near puberty yet.  I didn't even start getting pubic fur until I was twelve.  But those articles also mentioned that girls mature faster than boys.  It was possible that he was able to have babies, even though he was still a kid.  

I read through every article I could find, trying to uncover some reason why this was actually impossible.  Unfortunately intersex boys weren’t even mentioned at all, so I was left to try and firgure this out on my own.  Some of the information was similar to what I learned in health class, and it looked like girls could only become pregnant after they had their first period.  That worked the same way for humans and morphs.  It seemed unlikely that Cody would have kept something like that to himself, but I would have said the same thing about him getting sick in the mornings, and he hid that from me.  I took a few deep breaths to focus myself, and shut down the tablet.  I had some very important questions for Cody, and this was going to be uncomfortable for both of us.

Walking back into the living room Cody was sprawled out on the couch, still totally naked.  I had to admit, even lounging around and watching cartoons, he still looked really cute.  His legs were spread open, putting his spade on display for anyone to see; thankfully that was just me at the moment.  His tail started wagging when came close, and he sat up to give me room.  I took my place next to him, and threw an arm across his shoulders, but Cody wrapped himself around me in a big hug.  He melted into my side, and I just sat there awkwardly for a few minutes, waiting for an opportunity to speak.  It became obvious pretty quickly that I was never going to find a good time to talk about puberty with my little brother.  So I just needed to bite the bullet and ask.

“Sooooo… I was wondering… have you noticed any, umm, changes with your body recently?”

Cody sat up, and gave me a funny look, before answering, “Huh?  Changes?  What are you talking about?”

I swallowed hard, and continued, “Oh you know, like have you been getting fur in new places, or has there been any blood coming out of your vagina…”

“Eww!  Kyle!  What the hell, why are you asking me that!?” he shot back, his muzzle scrunched up in disgust.

“It’s totally normal, I promise!  That’s just what happens when you get older, and your body starts to change.  I was just wondering, because you’re a little different, if any of that stuff has happened yet.”

His eyes darted downwards, and he mumbled, “Umm, I don’t want to talk about this now.  Ok?”

I sighed, but kept pressing him, “It’s just, this is kind of important.  I promise I won’t say anything to Mom and Dad, but I just want to make sure everything is ok.”

There were a few long moments of silence, then Cody sat up straight and looked away from me.

“Well, uh, there was this one time, a couple months ago.  I sorta felt like crap all day, and then there was some blood in my underwear when I went to the bathroom.  But that was the only time, it hasn’t happened at all since then.”

I felt my heart freeze in my chest, and the blood drained out of my face.  I had to actually will myself to start breathing again.  I forced my ears to stand up straight, and tried to fake a smile.  One more chance for salvation had been thoroughly smashed.

“Why didn’t you say something when it happened?  You don’t need to hide stuff like that from me,” I said, trying to reassure him.

“I know, but it’s still embarrassing.  And besides, that was back when you weren’t talking to me for a whole week…”

I winced a little at the reminder, and said, “Ohh… Sorry again about doing that, and, umm, thanks for telling me now.  I know you don’t like talking about this kind of stuff.  Say I need to go out real fast and run to the store, do you want me to get you something?”

Cody looked at me, confused, and said, “Wait, like right now?”

“Yep!  Right now!  I just realized there is something super important I need to pick up,” I said, hoping I didn’t look quite as crazy as I felt.

“No, I’m fine.  Kyle, is something wrong?  You’re acting kinda weird.”

I really didn’t want to tell him the truth, but I wasn't going to lie.  I just sighed, and looked him right in the face.

“I dunno.  Maybe.  I’m not sure yet.  Just hang out for a little while, and I’ll explain everything when I get back, ok?”

Cody looked worried, but said, “Ok…”

I walked down the apartment stairs, and unlocked my bike from the rack.  The pharmacy was about three blocks away, and that unfortunately gave me time to worry the whole way.  Soon enough I was there, and began my search for something I never thought I would need: a pregnancy test.  The store wasn’t especially busy, but there were still enough people milling around that I felt incredibly awkward.  I wandered around the store until it looked like the coast was clear, and then slipped down the family planning aisle.  There were so many different kinds of tests, I didn’t even know where to begin.  Most of the brands were for humans, but there were also about a dozen varieties for other species.  I just ended up grabbing the cheapest one that said canine on the front, and got out of there quickly.  

I picked up a bag of candy to hide the box behind, and then tried to figure out what to do next.  I could not be seen buying something like that.  A fourteen year old buying a pregnancy test was sure to raise a few eyebrows, and I couldn’t risk letting anyone know what I had done.  I know now that fear was unfounded, but at the time I was just a scared kid.  I actually gave serious thought to just shoplifting the damn thing, but thankfully that never became necessary.  The store had a few of those self-checkout lanes, and I quickly scanned my two items and threw them in a bag to keep it out of sight.  It was a small mercy that the test was only a few bucks, because I had just enough cash to pay for everything.  I bolted out of the store, and pedaled like a maniac back home.

I was totally out of breath by the time I ran up the stairs, and was huffing like a marathon runner as I entered our apartment.  Cody was still curled up on the couch, but had apparently put some clothes on while I was gone.  He heard me come in, and his head whipped around immediately.  Cody looked terrified.  It broke my heart to see him like that, but I felt even worse knowing what was coming next.

I pulled the candy out of my bag, and said, “Hey, I got this for you!”

I tossed it over to him, but Cody didn’t even bother opening it.  His ears were flat against his head, and his tail wasn’t wagging.  

“Kyle, what is going on?  You’re acting really weird and it’s scaring me.  Am I sick or something?”

I sighed loudly, and said, “No, you’re not sick.  Or at least I don’t think so.  But there is something I need you to do for me.”

“Ok sure…”

I braced myself, and then pulled out the pregnancy test.

“Can you pee on this?”

Cody looked confused for a few moments, until his face fell at the realization of what I was asking.

“Oh…”

“Yeah…”

He got up quietly, took the box out of my paw, and walked towards the bathroom.  A short while later he came back, holding a small white plastic stick.  He didn’t say anything, just placed it on the table in front of us, and sat down next to me.  I wrapped my arm around him, and pulled the boy into my side.  It’s hard to believe how long three minutes feels when you are waiting for something so important, but we simply sat together in silent anticipation.  Eventually I watched the last minute tick by, and picked up the test.

Two lines.

“You’re pregnant.”  It felt hollow and unreal to actually say those words out loud.

Cody started to cry immediately, and I just held his face against my chest as he sobbed.  

Everything was going to change now.
