A/N

Just tossing this out here. Pairing is Simon/Theodore. For those of you who don't like said pairing, you're welcome to leave. If you've decided to stay, then sit back, relax, and enjoy. Read on.

He sat at the wooden desk with one hand pressed to his cheek; the other was holding a pencil tightly, positioned over the white paper, awaiting a hint of inspiration to come to him. He wiped his forehead slowly before taking off his green turtleneck, exposing his chubby body to the air, sighing happily as the cool air caressed his form.

"Ahh… much better.." he whispered. 'Damn… why can't I think straight?'he thought.

The fourteen year old, named Theodore, had been assigned to write a page about the mating habits of his species for a school project, and his idea tree proved to be utterly fruitless. He'd even tried looking up images online, which only resulted in his own arousal.

So there he was, uncomfy, horny, and still struggling. 'Ugh… I can't think straight like this… I gotta let off a load…'

Theodore moved away from the desk and made his way to his bed, laying down on the soft green blankets. His hand went under the pillow, returning with a jar of lube, and a 10 inch long, ribbed dildo, with a few thick 'veins' along the length, colored a dark green.

He pulled off his tight underwear, letting his erect, seven inch, uncircumcised cock spring upwards, standing stiffly at attention, already leaking a small amount of precum. The young munk pulled back his foreskin enough to expose the head of his shaft, glossy with a coat of warm pre.

Opening the jar, he put a nice amount of the slick substance in his palm and smeared it all over the sex toy until almost every inch of it was surrounded in semi-warm lube. Theodore rolled onto his belly and lifted his chubby ass from the bed. He reached behind himself and spread his plump buttocks until his twitching asshole was revealed.

With the toy positioned right at his entrance, Theodore took a deep breath. He nearly squeaked out loud as the thick head disappeared inside him, stretching his hole wide open. His breathing quickened as he steadily eased even more of it into himself.

One inch, two inches, Theodore closed his eyes as pleasure surged through his body. His hand wrapped around his cock, pumping it up and down his member in pure bliss. A thick strand of precum jetted out of his cumslit, staining the blanket below.

Three, four, five, six, he squirmed around, clenching his anal walls powerfully around the dildo as it went deeper and deeper. Pre was coming out of his cock freely, forming a puddle between his knees. Finally… Seven. The toy was pushed inside of Theodore's rump as far as he could get it, and he let out a loud moan as he grabbed the last remaining three inches. He released his grip on his cock and began to push and pull on the dildo, twisting it around every now and then.

Red hot waves of pure pleasure rushed through his little body, sending his mind into a wild spin. His breathing became much heavier, panting loudly as he switched his position. Now he was laying on his back, with the entirety of his cock inside the moist warmth of his mouth, sucking on his member as hard as he possibly could, loudly gulping down his own precum greedily as it splattered into his maw.

He was moaning quite loudly around his mouthful, roughly fucking himself with the sex toy as he neared his climax. Theodore didn't worry about anyone intruding and seeing him like this. Alvin was out for the night, Simon was down in the basement (A.k.a., His lab), and Dave was out at the store.

Breathing a little louder, he let his length slide out of his mouth and his legs flopped down onto the bed. Theodore nearly screamed out in pure, wild pleasure as a mighty wave of euphoria took ahold of his body, nearly pushing him far over the edge.

"My my. Someone's a naughty little munk, isn't he?"

Theodore's eyes flew open in total shock at the sound of Simon's voice. He tried to scream out of fear, but Simon covered his mouth to muffle it, leaving the younger munk silent. The taller boy lowered his head until his lips wre right by Theodore's ear.

"Don't worry… I won't tell anyone…" he whispered.

Simon moved away from him slowly. Theodore saw that all Simon had on was his dark blue briefs, which had quite the noticeable bulge directly on his crotch. The blue clad pressed his lips directly on Theodore's in a hot, passion driven kiss.

Taken my total surprise, Theodore parted his lips slowly. Something hot and wet, a little slimy, slipped right inside, exploring his equally hot mouth. It was Simon's tongue, gliding against his own as they exchanged their saliva, pushing it in and out of each other's mouths.

*Theodore's POV*

I was stunned beyond belief. Simon was right on top of me as he made our kiss deeper, pinning down my tongue with almost no effort.

He touched all over me with his nimble paws, caressing every inch of my body. Everything he did was so lustful, yet passionate. Right and wrong at the same time… no…. just right… oh God it's sooo right! I could feel his bulge prodding against my balls, and I blushed a bright shade of red.

Unfortunately, our kiss didn't last for long. When he pulled away, there was a bridge of our combined saliva connecting our bottom lips.

Then, he placed a few soft, wet kisses on my neck. He made a trail of kisses from my neck, down to my chest. My blush deeped by a shade when Simon gave both my nipples a loving kiss, which were already erect with pleasure.

"S-Simoooon!" I cried out, shutting my eyes tightly. My older brother had dragged his slimy, hot tongue over my sensitive nipples. I grabbed his head gently to hold him to my chest, panting loudly with desire.

His tongue continued to flick against the right nipple and his hand was roughly pinching the other, giving it a good tug every now and then. I could tell that he was enjoying this as much as I was. Simon's cock was throbbing like crazy against my own, as if it was begging to be released from its tight prison.

I groaned loudly as he pulled away from my chest to continue kissing down my body. Next, he stopped at my belly. Both of his wonderful paws were rubbing and squeezing my chubby stomach, and I moaned in approval to his gesture. A loud sound, a mix between a laugh and a moan, escaped my lips soon after.

*Normal POV*

Simon pressed his tongue inside Theodore's navel, licking all over his sensitive bellybutton without the slightest trace of mercy. Theo was forced to let out loud laughs and moans as he squirmed beneath his older brother, holding his head to his wide tummy. Thick, sticky spit was filling Theodore's navel with each lick he received from Simon, only to have it licked up just as quickly.

"Heheha haaaahh! Hahaharder!" Theodore lsughed. He was wriggling around nonstop as Simon's tongue only pressed harder on his navel. Several minutes had passed before Simon stopped to let Theodore catch his breath.

As the younger munk recovered, Simon yanked off his own underwear. He, like Theodore, was uncircumcised, standing completely hard at an impressive eight and a half inches, and was about an inch thick. Simon rolled the chubby munk onto his back and pulled the dildo out of his asshole easily.

Theodore nearly unloaded his cum all over his own belly by then. The pleasure building up in his body was like a fire spreading throughout him, making him hotter and hotter with every minute that passed. What Simon did next, left Theo with a major blush all over his cheeks.

He sat down in front of the younger boy with his legs spread wide, exposing his crotch to his little brother. Simon grabbed the back of Theodore's head and pulled him closer until his nose was pressed lightly against his balls.

*Simon's POV*

"Go on, little bro…" I whispered.

I blushed as Theodore started to sniff at my balls. I could tell he loved the musk coming from them, because his entire body shuddered as he did so. Theo rolled onto his back, keeping his nose at my crotch to inhale the heavy musk that was around them. Leaning forward, I had us in the 69 position, admiring his uncut cock from up close.

He was emitting the same arousing scent of musk that I was, and my mouth opened in anticipation. I pushed back his foreskin, which had somehow went back to cover his cockhead, and took his entire dick into my mouth, licking and sucking on it as hard as I could manage to.

Theodore yelped loudly from pleasure and wrapped his thick thighs around my head in order to keep me from moving away from his musky crotch. I let out a muffled shout of blissful pleasure as my own cock andballs went into Theodore's mouth.

'D-Daaamn… oooh fuuuck… he's hornier than meeee…'

I felt every last part of his mouth, even some of his throat, using everything he had in order to get me to bust my load for him. He was sucking from my cock like an infant sucks from its mother, and I just kept feeding him my precum.

Right when I was about to cum all over his face and in his sweet little mouth, I pulled myself away from him, panting loudly as the feeling started to die away. I put Theodore on all fours, like a dog, and mounted him from behind.

"How much do ya wanna cum, Theo?" I asked. He let out a loud whimper as he tried to scoot himself onto my length, which I quickly refused by moving my hips away. He turned his head back and looked at me. His eyes were a shade darker, filled with unimaginable need for me.

Then he spoke, making me blush a darker red than Alvin's shirt.

*Theodore's POV*

"P-Please Simon… Please gimme your cock… I need your thick munkhood pounding the innocence out my ass… make me yours, Simon… just please… pleeeease fuck meee…" I begged. My voice was slightly quivering as I held my gaze, staring directly into his grey-blue eyes.

He nodded and laid directly on top of me, wrapping his arms around my thick belly in a loving embrace as he pulled me into his lap. I kept myself as still as possible as I felt his cockhead pushing against my twitching asshole.

'Go on in….. I want you to…'

My breath got stuck inside my throat, stopping me from screaming out Simon's name like a bitch. Simon had forced every inch of his cock into me, going in much deeper than the didlo had. It felt like Simon was at least nine inches long, if not longer, I didn't care. The pleasure was too amazing for me to care.

"AAH! FUCK ME SIMON! I NEED IT! FUCK MY ASS UNTIL IT'S NUMB!" I finally screamed.

It felt like Simon's dick got hard as steel when he pulled out of me. My asshole clenched down powerfully in a pitiful attempt to keep him in as deep as possible. He dove right back inside my rear, and pulled back out. In and out, in and out, over and over again, each time forcing out a bitchy moan from me.

He pumped himself in and out of me quite roughly, prodding all of my most sensitive spots with every thrust of his powerful hips. I felt hot precum squirting out of the very tip of my cock, a nonstop flow of natural lube just splattering onto my cover. I had to bite down on a pillow in order to not make too much noise, just in case Dave decided to come home early.

"H-Holy shit… Theo… your ass is amazing…" Simon growled. His tone was rough, but not in an intimidating way. Almost like he was struggling… He leaned down and nibbled behind my right ear, one of my various sensitive points on my body. I swear I nearly screamed his name loud enough to wake up half the neighborhood. The pleasure shooting through my body was all too much… too muuuch…

I bowed my bead as low as I could, raising my ass closer to Simon's violently thrusting hips. His tip smashed into my prostate, grinding against it for what felt like an eternity before pulling away, just to hit it again and again, tormenting me with the indescribable pleasure that flooded my entire form. I couldn't even say anything, unable to beg him to fuck me like a little bitch in heat.

My mouth opened wide in a silent, final moan. I could feel the veins in my cock bulge out, making themselves visible along my shaft as my dick throbbed in absolute pleasure, spewing out countless gushes of my steamy chipmunk cum. The hot semen splashed onto my stomach, my bed, and even part of my face, making a total mess of myself while Simon continued to use my asshole as he pleased.

Simon didn't even stop as I climaxed. He just continued to fuck my ass as hard as he could, even spanking me as he neared his own orgasm. I don't know how long after it was, but he finally slapped my ass one last time and yelled my name at the top of his voice, burying his dick completely into my asshole. He stroked my cock all the while, finally dumping every last drop of his hot spunk into me.

A whimper and a whine rang from both of us as I came a second time, this load being much bigger than the last. Byu the time we both started our afterglows, my entire stomach, chest, and even my neck was coated in my own seed, and my ass was overflowing with Simon's jizz.

When he decided to pull out of me, he had it so that my butt was in the air. His cum dribbled out of my wonderfully stretched asshole like a faucet, down my ass crack and finally dripping onto the blankets under us. Simon kissed my lips again, but for only a few seconds before kissing my cheek and forehead.

"Wow…. That was totally amazing, Theodore…" he panted. "Oh… and I hope you can finish your assignment now…" he said.

'Hehe… I nearly forgot… but don't worry… that was more than enough to help me…'

We were leaning close to each other again, when someone cleared their throat. We both gasped and turned out heads to the door, just to see Alvin, completely ass naked with his uncut dick drooling with cum. There was a nicely sized cum puddle between his feet as he looked at us from under his cap.

"Room for one more?" he asked.

Me and Simon both gulped and nodded, smiling as Alvin made his way over.

'Hope you saved some for me…. You're gonna need it all…'
