Witches and concoctions

"So when the fuck did you hang out with the old coot?"

Talie walked ahead, the silhouette of her slim waist and wide hips in the light slowly coming towards us from the far end of the tunnel.

"It was a long time ago, you probably just don't remember. She- helped me with something and I was supposed to come back… eventually."

Her voice quavered and despite the lack of light, I knew she had to be blushing right then.

"And stop calling her 'old coot'. She was nicer than most people gave her credit for."

I rolled my eyes but didn't say anything. I sure didn't remember her being nice at all. The few times that I'd had the misfortune to see her outside she had just looked cranky.

Not to mention the rumors.

"Yeah Trev, it's impolite to talk about old people like that. She was probably just misunderstood and, well, obviously old." The blond said from somewhere behind me.

At the end of the tunnel we stepped through into something I'd honestly been half expecting. Dark, moody and smokey with what looked like a thatched roof overhead. Scattered bottles and books of such whimsical design as to be probably impractical. Pieces of plant life sat in bowls and pots either growing from them or placed as reagents clearly meant for the many concoctions of questionable aglow haphazardly placed about.

Bianca cooed as she skipped up next to me, sending her tits into a delightful display of gelatinous bouncing.

"This is so cool! Its like an actual potion shop!" She said as she poked at something that looked a bit like an alembic. It tinged clearly as her long nails made contact.

I followed after Talie as she walked between the cramped space, enjoying the sway of her body and the way that her shorts creased whenever she'd lean over as she seemed to be trying to find something.

"Ah, here we go."

On a far end of the room three oversized cauldrons bubbled, steam rising in billowing columns that curled in swirls just below the ceiling. Bubbles expanded and exploded, splattering over the sides and steamed as they made contact with the comparably cool floor.

In between the three, familiar glowing runes scrawled across the air.

"Pick correctly and move forward."

"Uhmm… pick what?" Bianca said.

Up ahead I could hear my sister sigh.

"We have to choose the right pot to submerse in, I think.”

“What?” she said, having seemingly caught the look on my face..

“I don’t know what else she would want us to do with a whole cauldron! She was relatively nice for a secluded old lady but I won't deny that she was a bit crazy!”

“Okay okay… so no hints at all, that’s greeaaaat sis.”

“Well-er… there could probably be a hint somewhere around here, it’s just…”

I followed her gaze over, the seemingly endless mess of haphazard and confusing concoctions and mixtures littered everywhere.

Our hopeless staring was interrupted by a sudden keening cry… and the horrible sound of flesh sizzling.

I turned my head just in time to see the wave of bubbling fluid spilling over the rim of the left pot as a few strands of blond hair disappeared into the swirling mixture.

“Ohnononoooo-”

I was surprised to see the worry on Talie’s face as we neared the cauldron, the opaque green fluid mostly still now. Occasional bubbles expanded before popping but no sign of the girl within. The last of the blond strands floating on the surface singed away as we waited.

“Talie?”

I stared at my sister, looking for some sort of indication of what we should do. She ignored me, her eyes frantically searching along the edge of the cauldron slowly bubbling before us.

I could smell the somewhat acrid tinge to the air, as if something had been burned heavily. Yet weren’t burned body's supposed to smell worse? It was fairly potent, just not entirely unpleasant as a hint of a… musky scent intermingled.

In fact that more musky mixture was growing stronger and… something was happening to the cauldron?

The expanding bubbles increased in number and pace rapidly, spurting so aggressively over the edge that both Tal and I had to step back to avoid getting singed.

“PL-aaah!”

Arms exploded out from the pool, grabbing the sides as a green-slimed Bianca pulled herself out from the sludge, unceremoniously dropping her to the ground right in front of me.

“Haa-ooh-haaa, wow! That was the craziest thing I’ve like ever done!” she said through spluttering coughs. Big gobs of the green stuff splattered to the ground as it sludged off of her.

Except… it wasn’t coming off as much as I thought… My eyes widened as I realized that her whole body had turned green. From her hair down, to her eyes and down the rest of her curvy… naked figure… it was all green!

“Ohhh! Sorry, soso sorry! No! I mean, fucking dimwit! Why did you do that!? Are you stupid!?” Talie ran over, grabbing her friend in a tight hug. It seemed to hurt her slightly, going by the way that she seemed to wince any time her skin made contact with the goo still clinging to Bianca’s nubile skin.

Speaking of which… Bianca was naked, very naked and the more I got to look at her, the more I realized that more had changed just beside the color. Bianca had been curvy before but this was… impressive. Big tits, huge ass, wet pussy…

“Don’t worry Tals, I’m not hurt, I mean- it hurt for a bit but I’m fine now!” she said in an overly bubbly tone.

“But don’t let go of me just yet. This… this feels real nice…”

My eyes followed as this curvy leprechaun of a girl began to rub her juicy lips up against my sister’s leg, cooing in a way that made my pants feel tight.

“Trevor! Stop staring!”

Talie stared at me with something akin to murderous intent as she grabbed a nearby sash and tossed it over Bianca’s shoulders, seemingly unaware of the mess that Bianca was currently making on her thigh.

“Okay, okay. Sheesh! Didn’t know you were such a prude. God, guess I’ll just figure this shit out then…” I said, throwing my hands in the air.

Which is what I turned my focus to. Clues…

“Fuck.”

It was all a mess, just tables and cupboards and stations for concocting probably more of what was in the cauldrons.

Maybe I could just “roll the dice” and hope that the one I picked of the two wouldn’t apparently first disintegrate and then remake me as… something. Probably not a great option.

As I wandered between the many precariously positioned and very breakable decanters filled with ominously glowing liquids, I continued to hear a growing argument between the others. Well I say argument, more like Bianca was clearly too horny and my sister wasn’t having any of it. Exaggerated moans and purrs would be followed with “No! What?! Why are putting THAT on me! Bah! Stop! What is wrong with you!?”

Meanwhile I was having no luck in discerning anything that could possibly be called a hint or a clue. That is until I found a note-er-more like a half-scrawled piece of some mixture probably meant to give a horse three left feet.

“2 grovesbacham, 2 lillysnatch and 2 oversized mungle trout. Make sure to mix for 2 minutes exactly!”

Perfect! To have the number 2 written for every ingredient in this uh… potion mixture? It just had to be the clue! To use the second of the three cauldrons. Yep, the last bit talking about “maybe add half a minute if it’s not done, idk, I’m not your mom. Doofus.” was probably just flavor or to throw off people of less conviction.

Pulling in a breath, I walked confidently to the second of the three cauldrons. To the side Bianca was still getting a little too handsy with her infuriated friend, too focused on their spat to notice as I climbed up to the edge and hung there for one moment, watching the lazily expanding blue bubbles spatter in the thick blue concoction.

Gritting my teeth and cursing whatever being thought it’d be funny to make me such a nice brother, I dove in.

I knew i’d messed up when I felt the pain. Searing, blinding, lots of words could describe that one hot second before the mixture had wholly consumed me. How did I know it incinerated my body? Well I didn't but the fact that I suddenly awoke to floating in thick water sure made it feel like that. Instinctively I reached out and pulled myself up to pull in a breath. Everything ached, weird twitches and flutters in my musculature that shouldn’t be normal told me that something had happened to me on a physiological level, just… I wasn’t sure what yet. I collapsed to the floor, staring up at the ceiling as I breathed in deep, easy breaths. My skin prickled as slime slowly pulled free, exposing me to the air. Vaguely, I could hear the muffled sounds of the other two. Their faces came into view above me… expressions of… worry? as my sister’s succulent lips moved rapidly.

“Are you Okay?! What the fuck Trevor!? I swear if you ever do something like that again I’ll fucking ream your ass.”

Ah.

Nice to see she still had her sense of humor. I smiled at her, my eyes lazily making their way down to her cleavage as sparks of excitement began to run through me. I watched the way they shifted as she leaned over me, the subtle swaying as gravity tried to take hold, abated by the supportive work of her bra underneath. She was too busy yelling at me to notice my ogling, so I endured. Oh how very… very difficult.

“It turned you into a girl idiot! Are you happy? You happy that you have tits and a big ass?”

My fingers lingered lower, skimming through the sludge still sloppily hanging onto my belly and then lower… finding my wet opening. I lazily roamed the familiar crevice, excitement budding as I pleasured myself, unabashed that my twin could currently see.

In fact… that made it so much hotter. Why- why hadn’t I thought of this before?

“Great! Now you’re a slut too! GAAAAH!” she growled with a cute exaggerated motion of her arms. She stomped away, which was a bummer in that I couldn’t watch her tits as much as her ass, but a girl’s gotta take what she can get I suppose.

Following her retreating form led my gaze up to the goblin-esque visage of the other girl who’d come with. Big tits hung heavily before me, lingering below a face born for sex and the juiciest lips I’d probably ever seen.

“I love the upgrade…” she said with a perverse little grin.

I didn’t know what in particular she was talking about but didn’t really care a moment later when I suddenly had a pair of lips on mine. I moaned, joining in the tossel of tongues and felt as her huge tits rested against mine, so slimy that they slipped off of each other like they were tit-phobic or something. I forgot about everything but those lips for a time, just living in the back and forth, the motion of our mouths and the exquisite attentions she was paying to my other lips down below.

I heard a splort and out of the corner of my eye I could see Talie just rising out of the last cauldron. Her clothes were nearly painted on, showing every juicy curve to her chest through the thin film of red goo staining her body. A perfect reminder of why I’d always been so in love with my twin. Not that "big tits" here wasn’t bad but… fuck did my sister have it.

I caught sight of the runes from before. They’d changed, saying something like “it was red, how bad can you be at this”. While further off two new openings had appeared, glowing with that eerie emptiness.

Briefly the thought flitted by that I hadn’t figured out what had changed about me but that took a backseat as Bianca began a furious rhythm on my clit, sending my juices flying as my body rocked in orgasm.

So I came, watching my disappointed sister watch me cumming my brains out to the view of her perfect physique.
