Me and my brother share a bathroom. My parents had the downstairs one and when I turned fifteen I got to move into the big renovated bedroom upstairs, now with an ensuite. I complained when I learned the bathroom had been put in for me and my little brother Liam to share.
"But, Da-a-ad, he's so messy."
"That's how it is David. You got the larger room so be thankful."
I think I had a right to complain, Liam was a messy little brother: leaving water all over the floor after a shower, and toothpaste dollops in the sink. But what really got to me though was the smell that would leak into my bedroom after he took a dump. Liam would strut out of the bathroom into my bedroom looking all proud, his shoulder length black hair a hastily toweled mess.
"Aw gross Liam! Go downstairs when you need to take a shit."
"Hehe David has to smell my farts," he would giggle, sticking his tongue out between his fat cheeks.
He was a little on the chubby side, with a thick back and the beginning of some prepubescent boy breasts to go with his large thighs and butt. He had a wide face and nose, and big eyes beneath dark lashes. He took after our dad. I took more after our mother, with brown hair and a face less round than Liam's. I was also thinner than my brother, your typical lanky teen. It wasn't that Liam was fed unhealthier food, he just had an insatiable appetite. Mum didn't know what to do with him. For a few months I complained about Liam's bad habits in `my' bathroom but eventually I gave over.
The shower and toilet were where I liked to jack off. Over the next few years, as I got more into porn - as any horny teenager does - I initially resented the demand Liam always placed on my time in the bathroom. But it's funny how much the internet speeds up the process of finding your turn-ons. I knew that I was gay because I liked gay porn, and I knew I liked dirty stuff. First I was into the idea of someone peeing on me, thinking that was very hot. Then smelling a boy's butthole appealed to me, then it was smelling their farts, and in no time at all I was into scat. Reading gay stories of men and boys pumping out thick, smelly logs got me rock hard every time. That's when I started appreciating the fact that I shared a bathroom with my brother.
His poo had always smelled bad, but as he got older, his dumps got ranker. After he dropped a load and left my room I was in there in seconds, huffing in the scent of his shit. Whenever he left a skid mark in the bowl I would use a finger to wipe up what I could. I would smell Liam's poo deeply, then pop the finger in my mouth and feel the bitter tangy flavour dance on my tongue. I started caring less and less about the cleanliness of the bathroom. Contributing to the mess myself I would leave my skid marks in the bowl when the flush didn't get them, instead of using the toilet brush like I used to. Mum complained to us but she rarely ever saw the bathroom anyway. And since I cleaned it myself every few months we were off the hook. It just felt so great to trash the room and make it smell with the help of my brother.
It wasn't until I was eighteen before things started getting interesting. One evening, after dinner, my brother walked past my bed and into the bathroom, closing the door behind him. I was messing around on my laptop flicking between tumblr and youtube. I was watching exercise vids to try and find a routine I could try out. I had gotten taller in the last three years and only recently I'd started to work out; Dad had installed a chin-up bar on my door. I was by no means muscly yet, I still looked quite average, but at least I was way taller than Liam.
I could hear my brother finishing up brushing his teeth, heard him spit a few times. The door opened and he walked out.
"Night" he said.
"Night."
He didn't look that different at thirteen, he'd just grown bigger in every direction. I never called him fat unless I was wrestling with him. He wasn't fat really, just a large boy. 'Thick', you might call him. Yawning, I went into the bathroom to brush my teeth as well, closing the door so I could piss first and look at my butt in the mirror. I was just about to sit on the toilet seat when something odd caught my eye. There, in the back of the toilet bowl was a skid mark, nothing unusual about it, I'd put it there only an hour ago. I had been quite proud of it because it was a particularly large skid. But once I realised what was different about it my heart started beating rapidly. Running horizontally through the track of my poo was a line of white porcelain. A perfectly finger shaped smear through my shit.
I bent down to look at it closely, not believing my eyes. A finger had been run through this soft, brown shit, there was no doubting that. Okay, think this through. Maybe Liam's hand slipped while he was wiping? No, this looked too deliberate. My mind was racing with the possibilities. My brother Liam touched my shit, out of his own curiosity or desire. I was getting boned up just thinking about it. Staring at the smear I started jacking my long penis. I came quickly, thrusting my hips forward I let out a ragged moan. I looked into the mirror at my flushed face and chest. I was probably getting ahead of myself. I had to remind myself how unlikely it was that my tough little brother liked scat. I got in the shower to clean off the cum. I thought about my brother for a long time, thinking about his hole and imagining it opening up to let out his shit. I came a second time. Then I heard mum calling for me to get out so I dried off and got in bed. I thought for a long while about what I was going to do, and once I had a plan, it was hard to fall asleep with all my excitement.
All I could think about the next day was what I was planning to do, and what outcomes that could have. While finishing my morning routine, getting ready for school, I noticed the smear in the toilet was gone, flushed away. Most likely with the help of the toilet brush. It wasn't crazy for Liam to brush away the skid marks, he'd done it before, but the clean toilet boded well for my theory. I figured that Liam had noticed he'd left his paw-print in the mud and decided to clean it up.
After school my brother and I had kicked off our shoes, got snacks in the form of doritoes and dip, and started watching cartoons. About forty minutes in Liam headed off to the bathroom. I was anxious and excited. I adjourned my cartoon watching time when he got back, saying I'd chill in my room for a while. Liam headed to his as well. Immediately I went to my ensuite and when I smelt the faint acrid aroma left after a nice stinky dump my heart beat faster. Hopefully I would be able to enact my plan immediately. Liam didn't always poo straight after school but I'm glad he did today.
I looked into the bowl and -- yes! There was a skidmark there, reasonably wide too and perfect for what I needed. Hanging my face in the bowl I took a big whiff of my little bro's shit. It smelt to tangy as to be almost sweet. Sexual thoughts started taking over my mind. I knew what a perverted thrill I was about to get. Hesitantly, careful to make sure I was obvious but not too obvious, I placed two fingers next to the skid, then swiped right through the middle of it. Once I was through the skid I dragged my fingers a little bit further, to make clear finger traces with the brown. I had scooped up a nice little lump of soft boy poo. Marveling at what I had done I inhaled my fingers deeply before stuffing them in my mouth. I sucked the shit from them and mashed it with my tongue, savoring the bitter taste. What I had done was such a risk. I could have made all this up in my head. My brother could really think scat was completely disgusting. Hornyness was not going to let me think clearly but I wasn't about to argue with it.
Fuck it, I decided. Jacking my rigid meat I aimed my penis down at the shit smear, it's head going purple with the pressure. Staring at my little brother's poo I came hard, squirting my teen load at the back of the toilet. I watched in bliss for a few moments as most of my cum dribbled down into the water to dissolve, but there was now an obvious glob of my semen plastered to the shit.
After brushing my teeth I left the bathroom to lay on my bed with my laptop, hoping Liam would need to piss soon before I lost my nerve and brushed all evidence of what I had done away. It took longer than I expected actually. Dinner was being put on the table downstairs when Liam finally walked past my bed and closed the ensuite door behind him. My heart really started racing then. Was he about to bust open the door and call me a freak? Would he even notice it? He was in there a long time. A shout came from mum downstairs for us to hurry up. I heard the toilet flush. Was that a bad sign? Liam came out of the bathroom and I knew he'd seen it. He was looked straight at me. He walked a little towards my bed and I was afraid he was going to attack. He stopped and, still looking at me, squeezed up his face and let out a sexy, squeaky fart. He smiled at me before heading downstairs as I sat frozen in place.
After sitting through dinner (I mostly stared at the TV, afraid to even look at Liam) my brother and I headed upstairs. There was a promise from dad that he'd come up in twenty minutes to make sure we were doing homework. In the hallway on the way to our rooms Liam let out some loud farts, to which mum shouted "hey, enough of that" from downstairs. We'd always farted about as much as two brothers would so it wasn't unusual. Liam closed his door and, still smelling the faint remnants of his fart, I walked trance-like to my room.
Jesus, what was happening. Would Liam taunt me forever now? Knowing that I liked the things his butt created. I did my homework. Then jacked off for about an hour, before falling asleep confused.
Liam farted a bit the next morning while getting his lunchbox packed, and when walking to the bus. At the first instance mum had said "oh, grow up boy," to which Liam giggled. I was so horny in class thinking about him. What was I going to do? I'd pretty much decided that my brother was too young to understand stuff to do with sex, at least stuff of such a perverted nature. Putting a finger through my shit must have just been Liam getting curious.
I was almost terrified when he sat next to me on the couch after school. Mum and Dad weren't nearby. Would Liam try anything? We sat there for a few minutes gazing at the cartoons, making comments about school, and munching on snacks. I saw Liam adjust himself from the corner of my eye and I looked towards him. He looked up at me and raised his leg.
"I've gotta fart Davy." He said emphatically.
Staring at me he let out a long high-pitched fart. I didn't react how i normally would to that kind of thing, calling him gross or punching him. I shuffled towards him and and sniffed.
"Smells good bro," I said, looking him in the eye.
This was the moment of truth. I pulled both my legs back, presenting my arse to my little bro. I bared down and mustered a short but pungent fart. Liam looked giddy, I could tell he was aroused. He leaned in to me sniffing.
"Mm it's nice" he said.
I smiled at him and touched his leg affectionately. At that moment the front door opened. I jumped back and stared at the tv while mum and dad entered the kitchen.
"Hey boys, how was school?" dad said. Liam was smirking at me.
I spent the rest of the day replaying the moment on the couch. Liam had called me 'Davy. He used to call me that when he was much younger. He had looked up to me then, and we were much closer. He seemed so much more independent now. `Davy' I thought. It was just about the hottest thing he could have called me. Maybe he was more sexually aware than I thought. The internet could teach you a lot.
Nothing happened for a few days between me and Liam, to my growing insanity. Our parents were always around. And then Liam stayed over at a friends house. And I had a big essay due, which dad made sure I worked on every night.
Finally a night came where we were home alone together; Mum and dad would be at a party until late. I wasn't sure how I'd instigate things, or even what we'd do, but my goal was at least to get an up-close smell of my brother's hole.
I would never have expected the surprise he had in store for me.
Mum and dad were awhile gone when I headed upstairs. I glanced in Liam's room but it was empty. I walked into mine and saw the bathroom door was closed.
"David," a hesitant call came from inside.
"Yeah it's me." I paused for a moment then added, "..mum 'n dad are gone."
Immediately the boy's voice became more confident. "Davyyy. Come in here and help me out."
My heart started beating fast. He'd called me Davy, and in almost a whine. The ensuite door was unlocked. I stepped in and Liam was standing there, stark naked. I was instantly aroused. I immediately noticed he was standing kind of funny, with his legs far apart.
"Uhm.. Davy, I kind of need to go to the bathroom. But I've been holding it so long and, well.."
He turned around in front of me, shifting his legs awkwardly, and there I saw a beautiful sight. Below that rotund waist, sticking out between his plump boy cheeks was the greenish-brown head of a firm turd. His anus was stretched wide around the monster. I wouldn't have expected such a large offering from one so young but Liam was a big boy who liked to eat. This was what a male was meant to be I thought, eating and farting and pumping out thick logs from his meaty body. Liam was just perfect.
All this passed through my head in a second. What I saw before me was so hot I could act only on instinct. I quickly got on my knees behind his pert globes, pushing them aside gently, his wide stance was already doing most of the work. His skin was so nice.
"What do you think Davy, pretty big poo huh?"
I could only mumble "Mhm, it's huge bro."
I could really smell the shit this close. A delicious aroma like cooked apples, broccoli, chicken, and mac and cheese. So savory yet rich and rotten at the same time. And above all those subtle scents was that quintessential poo smell, from holding a load in until it's pushing against your hole and farts keeps leaking out. That smell drove me wild.
I leaned in close, sniffing hungrily. I ran a finger over the stretched pink skin of Liam's anus, it clung to the turd, so thin it was almost translucent.
"U-uah," Liam whimpered. "What are you doing back there Davy?"
Liam's hole seemed to push out even further. With a `pfffft' sound a smelly fart forced its way from the boy's pussy lips. The stink was strong, it wrapped around my head and intoxicated me. How much broccoli has this kid eaten?
"Ungh, uhh, Davyyyy. It's coming!"
Liam's supple hips writhed between my hands as he started moaning like an animal.
"It's okay baby brother, i'll make it better." I said lustily, rubbing his thighs. "Give me your shit Liam. Feed your big brother."
"Yeah, its all for you Davy."
"Feed me your fat stinky log you smelly boy".
I opened my mouth around the turd, at the same time reaching my hand around to rub his belly. With my other arm I pulled my brother to me, connecting his body with mine. Instantly flavors exploded in my mouth, earthy, rich, and bitter. The dark log pushed further into my mouth until my lips touched Liam's hole.
"Davvyyy!" Liam whined.
I could feel the turd mass starting to push out, chewing roughly I swallowed my first chunk. Nothing was better than the feeling of it sliding down my throat. As his hole opened wider Liam started queefing around the turd, driving my sexual hunger. These weren't just the farts of a sexy boy; they were my brother's farts. I loved his stink more than anything.
The poop was pushing into my mouth faster now, my cheeks were bulging and I was continuously swallowing. Liam's meal was so delicious. I couldn't get enough of his tangy, creamy, slimy turd. It was so rich and rank, fermented shit from the rump of a teenage boy and the by-product of all the unhealthy snacks of a typical teen. With circular motions I rubbed his contracting tummy to sooth him, reveling in the slight bit of pudge.
He parted his thick legs even further so he was now half-squatting on my face. I felt him bear down, I imagined his cute face, red from all the effort, long hair sweaty, kissable lips parted. He grunted and a loud fart shook against my nose and tongue, simultaneously shit pumped into my mouth. The smell and taste made me dizzy as I choked down Liam's hot brown dump.
Liam was breathing heavily, "I pant think thats pant almost all of it."
I moved my hand from my brother's waist and took his hand in mine. I squeezed it affectionately. He squeezed back firmly, and kept squeezing as one last rush of gas and boy poop, much softer now, flooded my mouth. His hole was smaller now but still loose from being stretched for so long. I dug my tongue in deep, sucking out spurts of poo and searching for any chunks of shit still remaining, Liam moaned deeply, a guttural cry. It was incredibly hot coming from a teenager, let alone my own little brother. I pulled him down on top of me, gently lowering this big boy until he sat comfortably on my face. His soft cheeks melted around my face, this pale, stinky heaven finally smothering me.
There was something I needed to do now, and I knew I was doing it whether my little brother liked it or not. I lifted the heavy boy off from my face and laid him on his back on the soft shower mat. I pushed his legs up exposing his stretched, gaping brown hole. Liam's face was flushed, as was his neck and chest, he looked up at me slightly dazed, with a cute smile on his face.
"Big bro you ate my poo-poo."
I smiled at him and leaned in close to his face. "I love you little brother. You're my man." We were looking straight into each other's eyes, "I love you." I said again more forcefully.
He liked that, a huge grin split his face, but he also looked slightly embarrassed at such an intimate compliment from his big brother; these were powerful things for a young guy to understand.
I went back to viewing Liam's perfect messy hole.
"I'm gonna fuck you now."
"What -- ugh! I dunno-"
I sunk my long teenage cock deep into his hole.
"Aaaaaggghh, oHHHH!" Liam yelled.
I pulled him close, trying to fuse my body with his. I put my mouth on Liam's and after a brief moment it opened up, and I was kissing him deeply. Completely out of control with love and lust and I fucked in and out. Deep thrusts. ONE, TWO, THREE, FOUR, and then I was cumming. And my body exploded with pleasure. I pumped my cum into my brother with desperation. I was making him mine forever.
Panting, we lay there connected for a while. It seemed my brother had orgasmed too. I licked his few drops of cum off his belly. I appreciated his warm body, licking his little breasts and caressing his soft bottom. We were both breathing deeply so as to inhale his shit smell. The shit that was coating my dick and binding us together.
We sat like that for a few minutes, my tongue swirling inside his mouth, my nose smelling the coating his arse had laid on my cock. Then I licked clean both sides of his hole, gazing at his light covering of beautiful black hairs. When he was clean I gently moved my brother onto me. He complied and sat just above my groin. Completely nude his soft bottom was very warm. His face was flushed, as was his neck and chest, he looked down at me slightly dazed and smiling, and then he snuggled down on top of me and I hugged him close.
A few days later I hear the door open and look around from the couch to see Liam getting home from school. He says hey and drops his schoolbag, then walks over to me. Pulling his shorts down to his thighs he plants his ripe butt against my face and I open my mouth around his cheesy hole. It opens up and a fart blasts in my mouth. Surprisingly a turd starts to come out. It's soft and rank. My mouth fills up and my brother starts to pump his poo down my throat. It swallow it all gratefully. When he's done I give a few licks around his hole. My brother pulls up his pants and crashes on the couch next to me.
"What's on?"
I let out a rumbling fart and my brother sniffs the air appreciatively. "The cartoons don't start for like twenty more minutes."
"Oh, might make a snack then."
"Yeah get me those chips mum bought yesterday."
End.
