On a rare quiet sunset eve at the beach-house/hangar, Tails was getting drunk for the second time in his young short life.  The first time came from an argument he won against the twice-as-old Sonic about the question of maturity.  The second time came from an argument Tails was slowly winning once again.
	"You sure you're good for this li'l guy?" asked the hedgehog.
	"Who are you going to report me to?" the fox grinned wider.  "There's no cops here Sonic, that's why I live here."
	"Hah, I guess you got a point, but you're still pretty young to be drinking."
	"I only drink when I'm with you...that came out worse than I meant it."
The blue blur cackled at his friend's shameful grimace, waving it off as he grabbed a bottle of cider from the top shelf.  The house Tails lived in was partly made by himself, and partly scavenged from old refuse at the city dump.  The living room was cluttered with sofa, TV, carpet, and a whole kitchen along the back wall from three generations of technology.
Everything however had the Tails special, blue wires and additional widgets that helped regulate heat and function.  Right now however, Tails was enjoying his cider as him and Sonic kicked off their shoes and sat in front of the TV.
Five toes on each feet stretched out in relief, as they poured themselves a glass after kicking off their shoes.  The young two-tailed fox had much smaller feet than his friend, small yellow nubs of fur whilst the hedgehog had much longer sturdier soles, thick and coarse from years of mach speed.
	"Glad you at least let me pick the drink," said Sonic.
	"Compromise matters!" said Tails.  "Long as we both get something we want."
	"I just don't want you to black out and soak your big brain in beer, what if it gets all messed up?"
	"That's why YOU'RE here," the fox tapped him, "you're my uhhhh...what do you call those guys at the gym who make sure you don't hurt yourself on weights?"
	"I don't know," Sonic shrugged, "I never skip leg day Tails, you know that, I don't need a gym."
	"Hahah, yeah."
They both took a drink of the cider, which while wasn't strong was certainly more than enough to imbibe Tails with his small underaged body.  Sonic being in his teens was a little more capable, and as a result drank more of it.
	"Why do you wanna drink anyway?" the hedgehog slumped against the sofa.  "It's not that good."
	"Because grown-ups always talk about relaxing after a long day," said Tails, "do you know how much I DO every day?  Every day I'm just thinking super hard about positrons and wave conductors, I can't shut off!"
	"Wow, that sounds annoying," Sonic smirked, "I can turn off pretty easy."
	"Yeah, I envy you sometimes, you always seem like you don't have a care in the world, how do you do it?"
	"I dunno, I just...veg out," he kept drinking, "just stop thinking about stuff and let your body drop on the bed."
	"Wish I could just empty my head every once in a while," Tails downed a glass, "I know it's a weird problem to have, but right now I can't stop thinking about how chaos emeralds have the WEIRDEST fluctuating crystal matrices."
	"Maytresses, ya mean mattresses?"
	"No, no it's like what emerald is made of, normally gems just stay in one shape but chaos emeralds don't, that's WHY they're chaos emeralds."
	"Ohhhh...I thought it was cuz they CAUSE chaos."
	"That too, see what I mean?!"
	"Hey, why don't I teach you how to relax?" the hedgehog ribbed him.  "If you're having problems trying to unwind."
	"Sure!" the fox spun his twin tails excited.  "Teach me the art of laziness!"
	"Hey hey, it's not being lazy, it's self-care!"
Drinking up through the night, Sonic tried to teach Tails the art of relaxing.  A few non-exercises into unwinding, unthinking and unassuming made the fox somehow more stressed than before, as he ended up rambling about geology and emerald inconsistencies.
But after four glasses of cider, he finally managed to calm down and souse his synapses hard enough that he started giggling over the next half-hour.  His eyes rolled back with a panting laugh, muttering to himself some theorem that Sonic barely caught as whatever show on TV was being completely ignored.
	"IF I," began Tails, "shtarted flyin' right NOW, would I get arreshted fer drink-driving?!"
	"Mmmm dunno," Sonic chuckled, "could the cops even catch you?!"
	"Ah dunno, if'n I'm tired maybeeheheehe, r-remember I kicked all thoshe carsh down that shtreet, LIKE THISH!"
Tails tried to swing his foot in a massive kick, falling backwards with a crunch as he giggled with painful moans.
	"You alright buddy?!" Sonic smirked.
	"Yaaaah, m'fiiiine!" Tails waved.  "Kinda horny though."
	"Aww jeez seriously?"
	"Mmm, drink'sh affectin'...a-affectin' my thalamushushushushaursh", he tapped his skull and pulled his large ears, "huh...big earsh, you know that?"
	"Yeah, they're pretty big," the hedgehog ruffled his head, "big enough to stick things into."
	"Mmmmm like...that?"
The fox pointed between Sonic's legs to his dangling blue cock, the fox looking to his own yellow stiffy that was twitching with all sorts of ideas.
	"Whut if you stuck your penish in my head, right in my ear?"
	"Uhhh, what?" Sonic scoffed.  "C-come on Tails that's...that's dumb!"
	"If ya do it right I'll be dumb too," the little scientist cackled, "c'mon you shaid I have to learn how to veg out, why not get me there with yer thingie?!"
	"Cuz, first off, you still call it a thingie, second, what if I really mess you up?"
	"I'll tell you when to shtop!  Like you do when I drink!"
At first the hedgehog was reticent, rubbing his chin with a growing lust that was further aided by Tails leaning over to stroke him off.  They had experimented in the past, the young boy having such warm small fingers and a mind that memorised all of his teenage friend's special spots.
Sonic barely struggled to resist, looking over at Tails and his large inviting ear that twitched with anticipation.  His lust grew too high, aided by alcohol as he started biting at Tails' ear.  The child whimpered at the soft nibbles, stiffening even harder from Sonic's breath.
	"You want it that bad li'l guy?  Want me to fuck the smart outta ya with my big fat dick?"
	"Y-yeah, yeah," whimpered Tails, "d-do it, shove it right in there lemme feel it shtuff my cranium!"
	"Heh...alrigh', you asked fer it."
Grabbing the fox's head, the hedgehog started to mount his ear and slap his meat above Tails' eye.  With a clumsy shove he pushed himself in, surprised at how easy the first few inches managed to slip through before touching the eardrum.  A deafening squish came dripping through Tails' ear, moaning with a happy sigh.
	"Aaaaah...y-yeah...get it right in there Sonic."
	"Nnnngh!  Jeez you...feel pretty good."
	"Don't worry if you...pound me too deep, I can take it!"
A drunken cackle escaped his lips between moans of bliss, as Sonic fucked him a little harder to grind his shaft along the folds of Tails' ear.  The inner bones shifted slightly from being nudged by Sonic's length, grinding the glans at the hammer and trying to test how far he could push it.
Every thrust tapped at the boy's eardrum, wettening it with pre in hefty spurts as Sonic hugged his head tighter.  Tails kept steady from the rocking of hips, the blue balls slapping against his cheek as the young kit started jerking himself off.
Too young he was to cum, he relished the excitement of endorphins and the lustful surge of testosterone that kept the boy egging on his friend to fuck harder.  Sonic became more drunk, both on the cider and his lust causing him to slap his dick harder and harder into the ear.
	"Yeah, y-yeah, MMMPH!" Tails shivered.  "D-do it, do it, sh-shove it all in, SCREW MY BRAIN UP!"
	"AHH, NNNGH, y-you sure about that?!"
	"DO IT SONIC!  SHTUFF MY BRAIN, PLUG IT UP, MASH IT WITH YER F-FAT MEAT!"	
The moment he said this, he would regret it dearly, when it came moments before his short-lived climax.  His youthful stamina made the fox squeal with panting joy, his cock twitching in a dry orgasm that flexed with a brimming vein.  But of course that meant his lust would die down, his drunken revelry turning sober by the second.
	"Haaah, a-aah, okay, okay that, th-that's good!"
	"NNNGH, haaah!"
	"S-sonic, hey Sonic time out, we're good!"
	"Ohhh, damn this feels REAL tight!"
	"Sonic, SONIC, SONIC NO G-GET OFF!"
But the hedgehog was too deep in his bliss, grabbing Tails harder and fucking him stronger with a growing fear in the fox's heart.  Sonic was too strong to push back, and his grip was like iron as he fucked through the eardrum causing Tails to shriek.  A violent stabbing pain ripped into his head, cracking apart the earbones and deafening the fox one side.
A loud terrible pop silenced his ear, the raw vibrations of Sonic's cock diving deeper into his cranium all the more disturbing to feel.  He felt like a block of wood being sawed, as Sonic cracked into his skull and punched through his brain with a violent thrust.
	"S-SONIC, AAAAIIGH, S-SONIC S-STOP, YOU'RE HURTING ME!"
	"NNNNGH, A-AAAGH!  Damn this is the best hole I ever had!"
The boy would start screaming but by then it was too late.  Sonic was drilling deep into his brains, rich wrinkled meat full of exceptional knowledge of a young genius mind.  Now it was being severed, mangled and fucked with rapid humps of a teenage cock, stabbing each and every part of his intelligence.
First he lost his speech, a babbling mess of drooling gurgles as his eyes rolled up in anguish.  Then he lost his memory, his name and the textbooks he had memorised all smeared across Sonic's cock.  Following that went his reflexes, his mathematics, and his creative skill.
With each new part of his brain being turned to mush, the fox would spasm in gibbering fits as his hands and feet would twitch violently.  His fingers balled into whitened fists, his toes curled like claws made of fur, and the muscles of his soles would pull with such agonising force, that it looked they would snap.
Horrible sounds ululated from his throat, his feet twitching harder with every muscle pulling away from each other, toes stretching farther until one could almost see the joints between the little bones.  They were the last part of his body to keep moving as his head slumped into Sonic's arms, the hedgehog oblivious to his friend's death when he came at last in his brain.
	"NNNGH!  HAAAH, SH-SHIT, TAILS, OHHH!"
The most powerful orgasm he had from the sheer depravity, the blue blur hammered away at the dead kit's skull, spraying up a thick wad of jizz that stretched over the brain dislodged.  Half of it was punched full of holes, where his cum drizzled into and down the brain stem, leaking grey water down his balls from out of Tails' ear.
	"Hoo...jeez."  Sonic gulped stumbling back full of drink.  "I really tired you out huh?  Tails?"
The fox slumped to the floor, his little feet twitching away with toes rubbing the floor hard.
	"Dang, you always fall asleep after the fifth drink huh?  Well, I'm crashing here, so I'll catch ya in the morning."
Sonic stretched his arms and wandered off to his guest room, leaving a broken two-tailed fox on the floor.  With eyes glazed over and his toes tapping furiously before they would stop, the young brilliant inventor would end his life as nothing but a broken toy, his friend's cum drooling out his broken ear with little bits of brain.
