Black Mousegic [Chapter 1]

The book had come from the library. Not the section of the library open to the public, mind you. Actually not the section of the library Lambert was supposed to be in either.

The cauldron had come from a yard sale, kept in an old barn in the part of the rural country where you expect every forgotten building to contain either bats or black mold.

The time to track everything down and the willpower to take everything seriously… that had come from the combination of youth and foolishness.

Right now though, Lambert was coughing his lungs out as he bent double over the windowsill as a plume of smoke rose from their third floor apartment.

"Darn, COUGH, and to think that until this morning I didn't even know what an eye of newt was.. COUGH COUGH! Or a tail of newt... Or a newt come to think of it..."

Lambert wiped the spit from his mouth with his forearm as he came back into the room.

"Now, we're only missing the final ingredient: 'The blood of man who has not been touched by a woman-1 drop'. It says on the bottom of the page that neither mothers nor sisters count..."

"Does it specify virgin, or just no women?" Par asked as he wondered if he technically counted. He hadn't actually expected to spend the week trying to cast spells with his roommate, but the sheep had dug up a suspicious grimoire on some kind of library internship and gotten extremely excited.

Given that the book mostly seemed to detail potions as its source of magic, Par couldn't help but be a little excited too. He wondered if his chemistry degree would be worth anything at wizarding school. He knew a few tricks for synthesis and had access to a lot of good catalyzers at their university, but the ingredient list was strange enough that the mouse was admittedly mostly going on instinct as he tried to adapt a few things for the modern age.

Only one way to find out! I solemnly swear that I've only sucked dick for the past 20 years or so..."

And with that he pricked his own finger with a sewing needle.

"Ouch!"

The tiny  prick felt painful enough to erase the passing smile from his face... He liked it better when it was only a joke... Still, Lambert let one single drop of blood fall down into the pot before sucking on his finger. As the drop made contact, the whole mixture stopped fuming and boiling despite the fire still burning under it, and gradually started to glow with a faint bluish light. None of the ingredients remained in the homogeneous liquid, it was simply a pale blue translucent fluid through and through.

"Hey... That's not the colour of blood...."

"It's called a reaction, dingus," Par commented, rolling his eyes, but he grabbed a ladle and pulled it up to take a sniff. It didn't really smell like anything. He dared to touch it, just a light tap, barely touching his finger to the surface.

"Shit!" Par exclaimed as the ladle THREW itself at him, the fluid inside it shooting up his nose as he coughed... and an enormous beast of blue liquid rose from the pot and launched on top of him, sinking in his every orifice, flooding his ears and mouth as it forced its way inside of him.

Second later, Par stood on his knees coughing, the tub-sized pot of liquid showing no signs of its mass after having gone inside him.

Lambert was frozen in shock and could only watch as it all happened before his eyes.

"Holy... Dude are you alright?"

The ram turned off the stove and scanned the room for any trace of the liquid.

"Did.. Did we spill it somehow? Maybe I didn't see that well through the remaining smoke..."

The teary eyed sheep rushed to Par's side trying to help him up.

"No... ugh," Par spluttered as he stood up, "I definitely drank it all. I could feel it go in me, like ice in my veins..."

Par rubbed the red fur on his arms, trying to get it to stand down, "On the plus side, next game night I now know EXACTLY why you can't share potions and can troll my players a little bit with it~"

The mouse smirked a moment before immediately looking crestfallen... "On the minus side... I think this was a dud. I don't feel any different and there's none for you anyway."

"Yeah, and well I think we're not getting the deposit back either" Lambert said looking up at a large area of the once white ceiling now caked with soot.

"That book was a stupid idea... Let's ditch it and never talk about it again. With a bit of luck you didn't catch anything toxic in the process... Tell you what, let's drop our plans for the evening and take care of you! Can I do anything to help you unwind?"

He sheepishly held Par's right hand with both of his.

"I'm not even sure what 'absorbing cosmic energy when you reach your peak' would even do for us anyway," Par waved it off, "Sounds like it'd only work for an olympic athlete... but what we did get was still very interesting. I'll take the book if you're scared off, it's worth studying what DID happen in any case."

Par felt something groan in his pants and then spoke, almost automatically. "Although, what's this I hear about you sucking dick for twenty years? How come I haven't gotten any of that? I'm not too girly for you, am I?"

"Well, cosmic energy sounded like one of the cooler spells... I'm not scared per se, it's just if we're only gonna ruin the apartment further..."

Lambert almost flinched as he processed Par’s other question.

"Oh, errr, I may have bragged a bit.."

A silly grin started to form on his boyish face.

"But look at you! I felt lucky  you even talked to me... The way I saw it, a ripped mouse like yourself must have had tons of ladymice in his life anyway... I didn't even know you were into blokes at all!"

"Ripped? Me? Seriously?" Par ran a hand down his front, his rather slight pecs and exceptionally massive hips illustrating his point. "Okay I've got a six pack and that's not nothing, but you know I have the biggest ass on campus right? They put me in the top 10 curviest girls on campus as a joke at least twice before the professor made them not print that issue."

Par started to undo his pants, lowering the tight jeans and letting an explosion of thick thighs join the other messes in the room as he fished out his cock... a small, four inch thing already throbbing hard, barely noticed amid the rest of him when he was clothed. "But fortunately I'm into everybody. It's just hard to find people willing to let this top."

"Actuahahahahahahally...." Lambert's cheeks blushed as Par mentioned that campus magazine issue. "Second biggest... Do you remember that girl they put in front of you in last year's issue? The one with an Edwardian bonnet?..."

Par could probably remember the picture... The caption read 'goldie locks' due to the curly blonde bunches that fell across her shoulders.

"That was me... I swear you dress once as the shepherd from Toy Story as a joke on halloween night and these bastards will never let you live it down..."

Lambert unbuckled his pants, and as soon as the buttons came off his waist seemed to push the two halves of his jeans apart.

"Still, I'm sure we can tease this rod into an 8 incher if we try hard enough"He stuck out his tongue as he played coy.

"You're very welcome to try," Par said, getting into a more comfortable position and sitting down on their couch, legs spread wide. "I -assume- you want me to wait rather than face-fucking you on the spot."

"Sure! I'll get us started big boy!"Lambert kneeled before Par and the couch after he peeled off the rest of his clothes. Now that he stood there he gazed into the throbbing cyclop's one eye. It still looked cute to him, like an angry little worm. That sight would come to haunt his mind later.

"Look, no hands!"He said, sticking his tongue forward and into the mouse's foreskin... Tasting the glans underneath before he peeled that dich with his lips, taking it in...

"Yes yes you're very cute and haaaaaaaaa" Par's sass died on his lips only to be replaced by a moan as he came almost instantly. He had no idea Lambert was this good, or at least, he'd never felt so sensitive. His balls practically ACHED as they pulled on him, making him spurt into the sheep mere moments after he began.

"Oh lord, sorry, this never happens..." Par cringed at the cliched line, but he meant it. Lambert, however, seemed... very occupied... by what was in his mouth.

Lambert flinched as Par's balls hit his chin hungrily... and licked off the remains of mouse spunk from the overworked glans, though he was a bit disappointed… Still he took pride in his position as a slutty bottom.  He sat down gracefully, letting the cock out of his mouth and showing his semen filled mouth, tongue extended, to his master for the night...  Then he gulped it down in time to see the tiny worm soften back into its flaccid form. A flaccid, fat, 6 inches form. Could cocks be bigger soft than they were while erect? Lambert didn't notice past the fact that it dropped out of his mouth, but Par was bound to know his own body better…

Despite having just cum, Par didn't feel drained at all. If anything he actually felt more energized, reaching a hand down to fluff himself back up. "Y'know what? That was not okay, I'm going to have to give you a little more than that." His hand wrapped around his cock, demands in his mind that he be more confident, more powerful actually making his usually pathetic member feel bigger.

In a matter of seconds, Par had fluffed back up to full hardness, an angry vein throbbing across it as his foreskin peeled back to reveal a thicker glans.

“Hehe, that was fast... Do you like me that much? " Lambert put a finger under his chin, giggling in place as he tried to act cute.

"Say... It looks bigger than before doesn't it?” With a half aroused, half suspicious look, Lambert got his face closer to the veiny demon... his inviting lips extending... As much as he questioned the swiftness of Par’s recovery, he wanted that thick knob inside him…

"That's the power of CONFIDENCE," Par said bluntly, grabbing Lambert's blushing face and pulling him tight around Par's knob.

"And I wouldn't leave any partner unsatisfied, so chow down." Par tried to hilt himself, reaching a back of the throat he'd never reached before as his balls clapped the sheep's chin, sending stars through both of their vision. The mouth really did feel smaller than before, tighter, but Par was determined to last at least a little longer this time.

Although surprised and dazed, Lambert smiled around the demanding schlong, feeling the soft loving spanking of the mouse’s sack on his face. They would become much worse soon... Still he'd had horses before, and dogs, let's not forget about dogs, so his reflexes quickly kicked in to accommodate the enlarged mouse member. With his tongue pinned under the aching cum vein, all there was left to do was to deepthroat that rodent bone, and he started moving his head back and forth, his tongue leaving a warm, unsustainably soft sensation underneath the mouse's sensitive skin.

Par managed to last at least a couple minutes of enthusiastic, but slightly amateur, face fucking before blowing this time, his balls groaning as a load rose up in him. A load somehow much bigger than the previous one. Hotter, thicker, pouring right down Lambert's throat as an output that WOULD have been more at home on a horse flooded out of the mouse.

But that wasn't close to the shocking part. The sheep's jaw was FORCED apart by an unmistakable jump in girth, rock hard cock actively swelling inside him as the balls in his face grew just as much, instantly plumping to the size of lunchbox apples as they swung.

Lambert choked hard on the juicy load, he would have coughed it out if the swelling rod had let him... Something felt lodged deep into his throat, something that anchored the dick in place. He tried to pull Par's cock out but lacked the strength to do so. Gasping for air, he started hitting the mouse's thick thighs begging for help!

Lambert looked for something, anything to push back against... only to find his hand sinking into thigh fat, or disturbing the large meaty orbs in the quivering sack...

"Whew! Man, I am wired after that!" Par said, pulling Lambert off of him and setting him on the couch, actually bodily moving the sheep without seeming to notice his weight. "Thanks man, best of my life, mean it," Par leaned back, putting a hand down at his crotch. "Although to be honest I could... I could... uh..."

Par finally noticed that his cock was a pretty definitive eight inches. Eight inches and FAT, the veins still standing out on it even flaccid, his foreskin creeping up the glans but still longer and thicker than he'd ever seen it. His hand automatically patted his balls, and he felt the apple size orbs groan again as he sat there in shock.

Lambert lay on the couch recovering gasping for breath, his head resting on one of Par's ample thighs... It too looked bigger and more generous somehow... But then again everything seems taller when you're lying down... Lambert slowly caught his breath looking at the bitchbreaking  organ slumbering in front of him... It was so magnificent he could only look at it in awe.

"D-dude... Fuck... You didn't tell me you were a grower... Please try to warn me next time..."Lambert said before coughing a bit of white goop on Par's lap.

"I'm... I'm not though. Hell, how could this be a grower thing when I just came twice and this is apparently flaccid?" Par flopped the cock across his lap, admiring the weight he felt from it as it swung from thigh to thigh. "Four inches was my max this morning... unless..."

"Holy shit! Peak. Energy. The spell takes effect whenever I climax! THAT'S why I feel so wired. My stamina must go up every time I cum! That, and apparently a little extra downstairs..." Par grinned widely, buck teeth cocking to the side as he bent down, seeing if his naturally flexible body could reach his cock. Not yet. Not quite. "Oh that is WAY better than some Olympian thing."

Lambert looked longingly at the fat piece of ham moving away from his mouth and toward the buck teeth before he answered.

"I'm glad you like it hun... But you're thick all around like a horse's flare... I don't think I can take it in the front anymore..."

"Well that's probably fine. I don't need any more magical caffeine shots RIGHT now anyway. I feel like I should work out or something, see how fast I can run, and it's not like you'd want to suck me off while I'm rowing or lifting weights, heh..." Par joked before realizing he might actually like that pretty decently.

"Wait! The book. Now that we know it works, I have to be able to find something to make you a little stretchy or help me shrink down." Par immediately started reading the book, leaving his cock tantalizingly available on his lap... his tail snaking around from behind him to lurk next to it, occasionally flicking it with the pink tip

"Stretching sounds good... Hopefully we have the ingredients at hand..."

The book had a number of potion recipes as well as some written spells for more mundane tasks... Those only required speaking the words.

Burdened by seed, Lambert rolled on his belly, his torso lying on Par's thigh. I observed the spontaneous monstercock for a few minutes until he gave in to the temptation... lifting it up, feeling its weight... Holding the glans and peeling it with the fingers of both hands.

"Here, got a bunch of incantations that don't require any extras, this one says it will let you 'bend forever, break never' so just repeat after me." Par started to speak aloud, a low guttural sound in a language Lambert had never heard before, he actually wasn't sure how Par could even read that, but he did hear the syllables and felt them stick to his mind.

Par's body briefly glowed before Lambert's busy hands immediately confirmed the effects, the foreskin he had peeled back being pulled ALL the way back as it stretched easily in his hands, pulling inches away from the floppy spire with only an idle need.

Lambert spoke the words as best he could... To no avail. His voice didn't take that gutural quality, nor did he start to glow.

"So... How do we know if it worked?..."

Lambert let go of the stretchy skin as it went back to its thick unbending initial state and started tickling the underside of the mouse's knob.

"Try to take my entire cock obviously!" Par smirked, "I've had to actively try to stay soft, since you seemed to be having so much fun, but you've really gotten me going again so I'm raring to go, especially since that uncomfortable caffeine buzz went away after I actually cast a spell. Now that I know how to MANAGE the extra energy I can't see a problem to collecting some more..."

Lambert let go of the 8 incher and sat back down on the couch. "Right. Your turn big boy, I got you worked up, now I wanna see what you can do.... "

He got comfy on the couch, angling his rear forward as he started stroking his own meat. He was 8 inches himself, although his was more modest... Thin and sleek compared to the raging mouse's… "C'mon get up!"

"Oh, I see how it is, you say you want to take care of me for the evening and then as soon as it turns out I got superpowers I owe you something," Par teased... but obligingly got it up.

"I -guess- it wouldn't be too much trouble for me to sit on you, and if I -happened- to sit in such a way that you got the best ass your cock is logistically capable of reaching then that's not anybody's fault is it?"

"Ooooooh... Tempting!..." Lambert teased back.

"But as much as I'd love to stick my log between your cheeks, I don't think I win the size contest

here... Besides..."

He started spreading his legs apart, raising his ass tantalizingly over the couch. "Isn't it about time you railed me proper?"

"Yes I suppose so, well... good luck sunshine." Par rubbed one of his previous loads over his cock in place of lube - the fluid was definitely widely available. He flipped through the book quickly, finding a cleaning spell and casting it aloud as Lambert was subjected to the PROFOUNDLY weird sensation of having his insides and outs magically cleaned.

Par grunted, barely having to tense his crotch to rocket back to hardness fat pole throbbing before he pressed it against Lambert's rear. The sheep was INCREDIBLY soft, his cheeks practically heavenly, but Par was goal oriented, finding the anus and pushing against it... gently as he could, at first... but still rapidly sliding in, his supernaturally flexible cock perfect for squeezing into tight spaces. Before Par had even bothered to thrust, he was five inches deep, farther in than his entire cock merely an hour ago.

Lambert shivered as the spell did its work. All of a sudden he felt fresher than a kitchen in one of these Mr. Clean commercials. Par gave him no time to enjoy the freshness and cleanliness as he quickly rammed half of his stick deep into the ram's buns, heating him back up through the sheer might of its lust.

"fuuUUUCK! you don't pussy foot around do you???" Lambert's expression turned from one of pain to one of exhausted pleasure and contemplation.

"What do you mean? I haven't even hit your prostate yet!" Par objected, finally thrusting... and immediately pressing into Lambert's prostate. "Hell I'm intentionally using the flexibility spell to be gentle, but all I have to do is kinda FLEX my cock and..." Par's massive shaft immediately went from 'enormous, but friendly and accomodating' to 'violently relocating everything around him.'

"I was trying to savor it! I mean, you don't want to cum until I've unloaded and started growing inside you, do you?" Par teased, but undercut his intent by pressing against the lamb's G-spot a... little harder than necessary.

: "AaaaAH!" Lambert let go of the couch and reached for his belly where the pulsing shadow of the mouse's meat started to bulge and pulse.. It even held him upright for half a second before he dropped back onto the couch, teary eyed.

Fully inflating, the mouse’s glans crushed Lambert's prostate like it was pressing an orange. In an instant, Par had squeezed every ounce of juice out through Lambert's cock. Although this wasn't an orgasm, the sheep's cock went limp in an instant as the muscles around his ass were stretched too far to sustain an erection.

"aaaaaAAAaaaaaAAaaaaaaahhhhh!" It was hard to read Lambert's expression as his eyes rolled back and his tongue stuck out... But a deeply satisfied grin quickly reassured the mouse.

"FUCK. Fuck. Is this what that's like?" Par's eyes widened as he felt a pleasure he never had before.

The feeling of absolute domination. Of DESTROYING someone who begged for more.

"Oh, my new favorite toy. I certainly hope that wasn't ALL you have..." Par got rough, viciously pleasuring himself in his new cave, uncaring about everything he hit. The whimpers and moans of the sheep were ADDICTIVE, Par clawing at the sheep's back as he went harder and more desperately.

Lambert's thighs jiggled with each crushing blow Par visited on him, waves of fat propagating across his ass like waves across the surface of a pond which was just struck by a large rock. The pain of his stretched belly started to get to  the ram's brain though...  As the mouse continued to rock his world unabated, Lambert grabbed a hold of the rodent's broad shoulders, hoisting himself upright and going for a kiss... one that didn't quite reach the buck-toothed face.

Par pulled the sheep's face around, kissing him deeply... as he slam-hilted in the sheep... and came. His load was TOO big, too thick, too hot. It had to be at least a PINT, his insane production rising with every thrust... and that was before the growth. Par forced, FORCED two more inches inside his pet, stretching him out in every possible direction as his balls swelled to full sized apples even as they pumped deeper into Lambert's gut.

Par gave one final thrust to assert 'mine. my property.' before he withdrew his rapidly softening cock in a backspray of cum... and blood.

Par just whispered a few words - words he hadn't even looked at the book for - and Lambert's organs stopped bleeding.

He wouldn't clean the sheep up, though, not when he looked so much better like this.

Lambert stood still, briefly managing to sit on the couch before he fell to the ground near Par's feet... He may have been healed but only Par's stamina kept being magically recharged by the universe.... Using all of his might, he managed to roll around to lie on his back, looking up. His head had landed between the mouse's feet and he was looking straight as Par's sweaty nutsack.

"F-fuuuuck.. I love you Par... But I think I'm plum tuckered out..."

"That's fine! I'm almost done anyway..." Par grunted... and his cock refilled to full hardness immediately, the mouse having to grasp it with both hands in an attempt to get around the ten inch monster. Again he bent down, trying to self suck... and coming VERY close, able to get his lips and tongue on the monster but not quite stuffing it down.

"I think I just need ONE more size boost, and I still haven't given you a proper bukkake. So you just wait right there and I'll give you a shower before bed. I'm eager to see how much I produce THIS time..." Par felt himself up, fapping eagerly over his fallen victim.

"Heh... one more for the road eh?" Lambert tried to stand up and failed, slipping in a pool of pre back in his position. All he could do was look at the foreskin rolling back and forth over the pulsating glans, its one 'eye' staring deep into the ram's soul.

"Y-you know dude... There can be such a thing as 'too much of a good thing'..."

"Not from the good thing's perspective, and I'd say more of me would still be welcome..." Par grunted as he felt himself up, standing enough to slip his tail into his own backdoor and give himself a little self massage. "But don't worry, after this I should cap out at twelve inches. I'll dispel the flexibility spell and try its opposite instead, 'Immutable form'. After that my proportions won't be able to change any more and everything should be all set. I just need ONE more little

boost to make a spell that powerful stick...

"Cap out eh?... You're already putting all of the male porn actors I can think of to shame."Lambert rambled on in a barely audible voice as the sight of the knob pulsing at him started to lull him into a state of helplessness... It had a.. Hypnotic quality after all of this exercise.

"But what good is a cock no one can fit?.."People in his position really shouldn't keep their mouths open that long...

"One way or another, that's a problem I can solve with POWER," Par thrust into his own hands, eagerly grasping, loving every inch of his growing girth. He'd never felt something so hard, so weighty, so perfectly veiny and fat in every dimension. Teasing his foreskin and feeling how it stretched was amazing, newly grown nerves pulled and teased as he played with himself. He loved this. He loved having what was probably the world's best cock.

He'd love even more having DEFINITIVELY the world's best cock.

Par came, a literal, actual gallon pouring out of him as he clutched himself, rope after thick rope painting Lambert's face and chest, almost bowling him over as Par simply spurted again and again. He shuddered, feeling his dick grow even further in his hands, his balls swelling to perfect grapefruits, and his body glowing as he grew ever more powerful.

Par let go, leaving the sheep to look over him through a cloudy haze of pre, the mouse's footlong monster swinging between his thick thighs, massively wide around the middle even when flaccid and showing every contour as it dangled, foreskin drooping faintly over the head as it continued to drip more cum than most men had in their entire loads. Even soft it boasted what it COULD be at any second.

The spray hit Lambert square on the cheek, forcing his head to the ground again, and again and again, So much so that he could no longer maintain eye contact. Whatever line of sight he could have drawn though, it wouldn't have lasted long, as soon he was covered in an immaculate coat of spunk. Not seeing through the white gunk didn't make it any easier though... Spurts of unseen and forceful cum made it through his nostrils, through his lips, under his eyelids.... Lambert was utterly violated and desecrated by the mouse's virile lust... And he loved every moment of it...

Nothing lasts forever though, and soon the ram was left spitting back out whatever he could, a small jet of cum making it through his mouth like water through a whale's blow-hole.  Lambert used both hands to try and clear the slimy gunk from his face.

"Love you Par... We'll just have to find a way to fix all of this tomorrow..."

He tried to get up, but it was already hard before. Now the floor lacked any form of adherence because of how thoroughly lubricated Par got it. He slipped around in the mouse's mess for a good minute before admitting defeat.

"F-fuck... I'm beat par... Could you help me into my room?..."

"Sure thing!" Par said with a friendly smile, immediately reverting back to roommate mode... as he levitated the sheep through their apartment, pulling him through the air and lying him delicately on his bed.

"Here's even a goodnight kiss..." The mouse briefly dipped his balls to Lambert's mouth, giving a final salty taste to punctuate his nightly smorgasbord.

"But yeah, everything should be fine tomorrow~" Par teased, heading off to his own room... to begin the ritual of immutability. While making it make his cock stop growing so... disproportionate... WAS an effect, the main effect would really be making it so nobody could ever take this away from him, but Lambert certainly deserved a turn to have fun trying!

Par slunk into the sheep's bedroom, watching him for a bit and sitting by his bed, thinking.

He didn't really feel sleepy. He wondered what else he could do tonight…
