Drinking Brothers
By:Pupupdown

"Alright I'm heading out. I'll be back by sun up, don't burn the house down!" Marcus's mom joked as she left the house. It was a hot summer night and she was going to be spending it with her friends leaving her son Marcus, a 20 year old pitbull with grey fur to watch over Sebastian, his 11 year old brother with a matching coat; and his friend Felix, a 12 year old golden barn owl, for the night.

Marcus wasn't too keen on having to babysit his little brother plus his feathered friend while his mom had a night on the town, but seeing as he was still subject to the "my house, my rules" argument his mother had been using on him since he was a pup he'd just have to suffer on with the two little ankle biters. speaking of..

"Can we order pizza!" Sebastian asked running up to Marcus with a gleam of hope in his eye.

Marcus just looked down at his little brother then to a nearby clock on the wall. '6:23pm" he thought to himself.

"No way, mom fed you two less than an hour ago" he responded, shooting down the cub's grease laden dreams, even hearing a soft "aw man" from Felix in the next room over.

That didn't exactly stop Sebastian who still begged his big brother to order a pie for the three of them. Marcus just ignored his pleas knowing that the more he told him no the more he'd insist. Eventually just walking past the smaller pitbull and making his way upstairs.

Ignoring the disappointed sighs from downstairs, they'd get over it soon enough, Marcus entered his bedroom closing and locking the door behind him. He had an issue that needed his immediate attention.

It had been two days since Marcus last jerked off which, to most, isn't much but Marcus wasn't like most he had a burning sex drive, one that never let him stay flaccid and satisfied for long. Reaching down to his crotch he felt up his balls to see just how pent up he was, each nut was the size of a fist and packing a hefty weight that made them swing side to side with even the slightest movement, He barely even brushed against his sack but his cock started throbbing in response, begging for further stimulation.

But Marcus held out he couldn't rub one out just yet, despite the fact that his head was swimming with testosterone fueled desire, he knew he needed something first.

Walking over to his bed his 8 inch uncut cock, shamelessly slapping between his thighs, he bent down and grabbed something from underneath. It was a small pair of baby blue briefs, much to small for Marcus and his oversized package, but that wasn't the point.

These belonged to Sebastian.

The 20 year old loved his brother, more than any older brother should, but he didn't care he had humped his siblings pillows, blown rope after rope in his room and defiled nearly every toy the younger cub owned (all without his knowing of course), so this was practically routine for the perverse pitbull

Holding the underwear up to his face Marcus took a deep whiff, drinking in his brother's scent like his own personal aphrodisiac.

"Ahh fuuck" Marcus moaned into the cloth. His cock angrily shot out pre demanding to be touched, its owner all too happy to oblige.

Marcus got up from the floor and took a seat on his bed. Gripping his meaty manhood he slowly began stroking, savoring the feeling of his thick foreskin gliding up and down his shaft. The squeezing of his cock soaking his hand in precum.

His brain was alight with fantasies, all of them of his little brother groping, licking, or riding his big dick.

"Oh yeah stroke your big bro's cock, just like that~" Marcus moaned to himself, picking up the pace as he delved deeper into a particular fantasy.

*CRASH*

Marcus shot up at the loud crashing sound from downstairs. Groaning in displeasure at the fact his little brother probably just broke something expensive. Using his brother's underwear, Marcus wiped his cock and paws clean of any pre, stuffed his junk back into his sweatpants and went downstairs to see what matter of chaos the two unsupervised cubs had managed to stir up.

Turning into the kitchen Marcus saw Sebastian and Felix desperately trying to clean up what looked to be the remains of several broken glasses.

"How on earth did you two manage this?" Marcus asked more annoyed than angry.

Felix was the first to speak up, apologizing for the broken glasses and going on a spiel the older pitbull honestly wasn't interested in. But what did interest the older canine was his little brother who he noticed had snuck off and was now in his peripheral vision reaching towards the kitchen table.

Marcus looked over and caught the cub red handed with a bottle of their mother's whiskey.

As the two brother's eyes met, Marcus gave a devilish grin that only a sibling who had caught the other doing something they really shouldn't could, while Sebastian was frozen like a statue even Felix had shut up seeing that the ruse had gone bust.

"So this is what you two were up to? You guys think you're old enough to play bartender, huh" Marcus mocked, grabbing the whiskey bottle from his little brother and dangled the bottle above his head.

Sebastian tightly hugged Marcus while giving him the best puppy eyes he could muster begging his brother not to tell mom about this. The display getting a chuckle out of the older male as a thought began to blossom inside his mind.

Marcus pretended to stew things over in his head for a moment, throwing in a few quizzical "hmms" just to add to the authenticity. Before telling the two "sure thing. Your secrets safe with me" setting the bottle back onto the table Marcus then went over to the cupboard and grabbed several (non-shattered) glasses "just let me in on the fun too you sneaky bastards" he teased as he set the glasses down.

Sebastian and Felix were dumbfounded, staring slack jawed as their supposed supervisor poured 3 full glasses of whiskey.

"Well are you guys thirsty?" Marcus asked the two cubs.

"Yeah!" The two cubs said in unison, relieved that they weren't about to get a scolding.

Sebastian praising his brother for his coolness with the situation. But Marcus could care less for his brother's pat on the back; he had ulterior motives and things were just getting started…

3 hours later

Marcus was definitely feeling the buzz of the alcohol having taken 3 shots of the social lubricant his body had taken on a warm feeling to it. His inhibitions laxed and his judgment slightly fogged. "Perfect" he thought to himself.

Standing slowly, he went into the nearby living room where, as he expected, Sebastian and Felix were black out drunk. Not only could their young bodies barely handle alcohol they had also taken twice as much as him, much to his astonishment. But discovering his little brother could throwback shots wasn't what interested him. No. What he wanted was a perfect opportunity to take advantage of the cub that stirred up so many desires within him and this was the perfect chance.

"God, why do you have to be so hot" Marcus said to himself, biting his lip as he stared at his unconscious brother.

Sebastian was lying face down on the floor, drooling slightly as his big brother picked him up and slung him over his shoulder. 

Making his way upstairs he turned back and looked at the remaining cub. He'd be back for Felix, his lust for young cubs would make sure of that, but for now his entire world was his little brother's unconscious, vulnerable body.

He wanted to make this moment special, so the setting was everything. Walking down the hall he entered Sebastian's bedroom. It was a typical room for an 11 year old boy, light blue paint, a box of toys, even a racecar bed (which Marcus was secretly jealous he never had one as a kid).

Gently setting Sebastian onto the bed he stepped back to admire the cubs physique. His slender body, short stature, and pretty young face drove Marcus wild with lust. Impatiently he began stripping himself, throwing off his shirt and pants his cock bobbed up and down pointing strongly at Sebastian as if it had a mind of its own.

Marcus practically dived onto the bed to join his little brother once he was completely naked. Positioning himself over top of the cub he pulled him into a deep hug, casually humping against his shorts as he drank in his scent straight from the source.

"So much better than any drink" Marcus commented, the thrill of what he was doing more intoxicating than anything stashed away in their mom's cupboard.

Soaking his little brother's legs with copious amounts of pre he began working on getting him just as naked as he was. 

Marcus lifted up Sebastian's shirt over his head, throwing it off the side of the bed with disregard, but with being so pent up and impatient the cub's shorts didn't get the same treatment. The older pitbull instead choosing to just rip the garments and the underwear underneath in two.

"Finally~" Marcus said, his voice oozing with intent "we can finally be together like brothers should"

He towered over his younger brother, his cock giving a continuous stream of pre as he stared at his naked sibling who was blissfully unaware his anal virginity was about to be taken away from him.

Marcus's eyes trailed down his form, stopping at the prepubescent package between his brother's legs.

"Heh nothing special" Marcus noted. His own dick easily eclipsed his little brother's cock and taught little 'coin purse'.

Flipping his brother over onto his stomach Marcus spread his cheeks apart giving him a clear view of his little brother's puckering anus. It was a fleshy pink and pulsed with every poke and prod Marcus gave to it "Undeniably virgin" he thought to himself.

Without much regard as to his little brother's well being, Marcus lined up his throbbing cock with the cub's taint and slowly began to push himself inside.

"Hwoooo fuuuucck" Marcus moaned to himself, feeling his foreskin roll back leaving his head exposed as it pressed onwards smooshing the cubs prostate as he plunged his dick deeper and deeper until finally sinking all the way in with a soft *plap*

Marcus had finally bottomed out into his own brother, his hips colliding with the unconscious cub's ass. "Damn I should really take a picture of this" Marcus thought, some part of him not too, drunk with need wanting to preserve the memory of taking his brother's virginity, until he felt Sebastian slowly stir underneath him.

It was safe to say the cub was far from awake but the large intrusion of 10 inches of incestuous pedo cock made his body weakly try to get away from whatever was clearly trying to split him in two.

"Oh no you don't" Marcus chuckled.

Laying on top of the cub, he put all his weight onto his brother's body keeping him in place as he slowly began pulling his cock back out of his younger sibling.

"Mmmf you're so goddamn tight bro" Marcus moaned into the unconscious (and uncomfortable) cub's ear. An audible *schlk* resonating as he pulled further and further out.

Sebastian's drunken struggling was beginning to die down as the obscene amount of cock inside of him decreased, not that Marcus noticed or even cared, and somewhere deep inside the young cub's mind there was a budding sense of relief that whatever was harming him would be taking its leave, until…

*SLAP*

While only halfway out, Marcus seemingly spasmed, slamming his hips right back into his little brother, going balls deep once again in less than a second all over again and setting the cub's asshole alight with stinging pain that'd surely be felt in full whenever he awoke. 

"fucck yeah" he moaned "I couldn't stop fucking you if I tried bro" Marcus cooed towards his little brother, licking the top of his head before roughly shoving it into the mattress.

"Now let big brother show you just how much he loves you~" he said with an air of sadism.

After that he just decided to let loose, his hips becoming a blur as he resized his younger siblings hole.

"Oooh I've needed this for sooo long!" Marcus said to himself. His hips collided with his brother's ass, making a wet series of slaps that could be heard throughout the house, even loud enough to make any passerby on the sidewalk stop briefly. But the lewd noises of the one sided love making just served to push Marcus closer and closer to the edge.

The older pitbull was having the time of his life. He was finally sating a desire that had been simmering inside of him for years. His fat nuts slapping heavily with reckless abandon just served to remind him that this was all real and actually happening. His forcefulness threatening to shake the small bed frame to pieces, the whole while Marcus held his brother down for purchase to get as much of his throbbing cock deep inside of him.

His hips a blur, almost pulling all the way out with each thrust and his little brother's ass taking on a red tinge from the rapid slapping of his hips. His cub loving cock bulged out Sebastian's stomach in its incestuous efforts to seed a womb that wasn't there.

The feeling of dominating his own brother left Marcus's brain glowing, the pleasure from plowing the minor's ass was steadily becoming too much.

"AH YOUR TIGHT ASS IS GOING TO MAKE ME CUM" Marcus yelled out.

Ramming his cock back into the 11 year old one final time Marcus craned his and his brother's neck and pulled the sleeping cub into a deep kiss as he felt his ball tense up forcing cups of incestuous semen into his little brother. The sheer pleasure blurring his vision.

Each throb from his dick felt more intense then the last as he danced his tongue around stealing his brother's virginity and first kiss all in one night. Holding themselves as still as a statue he blew rope after rope of pent up pedo cum into the drunken cub. This single orgasm carrying behind it years of twisted desire and lust.

After nearly a minute of straight pumping his little brother's guts full of cum, Marcus's torrent finally ebbed off to a trickle. His balls noticeably smaller after getting to dispense their thick and creamy payload. 

Slowly dragging his cock out Marcus winced at the overstimulating sensations that surged through his cock, tugging against the vice grip of the cub's ass until he finally pulled free with a wet *pop* the thick load from Marcus steadily began to flow out

Staring at the thick stream of cum flowing from the smaller pitbull's worn out ass Marcus patted himself on the back as his dick slowly began to soften.

Whether his unconscious brother would've enjoyed the treatment or not was none of his concern; he loved his brother and he'd make sure he knew. Even if next time might need a little more persuasion.

"Now you rest up. I gotta go deal with your friend downstairs" Marcus said to his unconscious brother. His dick slowly beginning to perk back up to the prospect of round 2...
