“Hey folks, Vanessa here.”  A cute blonde waves from the video screen.  She’s sitting cross-legged on a bright green yoga mat in what looks like a small workout studio with parquet flooring.  There is a mirror on the back wall that shows a reflection of the video streaming rig and, more importantly, of her attractive backside.  A simple white crop-top shirt shows off a toned belly, obviously she uses the studio for more than just her videos.  Torn denim shorts and her usual black choker complete her simple ensemble.  The choker has the number seventeen written on it in sparkly gold ink.

She pats a cardboard box sitting on the mat beside her.  “Time to show off another fun toy.  Sadly, this one’s not for the mass market.  A local museum had this in storage, as it’s not exactly safe to have in public view.  The curator’s daughter is a fan, and she sweet-talked him into letting me borrow it for a show.”

She lifts the box, revealing that it has no bottom, and was concealing a large stone basin.  It looks somewhat like a birdbath, except the carving is far more ornate, with dancing figures etched around the edge.  Some look like angels, others look like demons.  “Behold, a classic example of a Banisher’s Basin.  These were believed to help rid people of troublesome spirits, especially those causing gout.”

Tipping the basin toward the camera reveals what looks like the shimmering surface of a pool of water, except that the water isn’t pouring out of the bowl as one might expect it to from that angle.  “Cool effect, isn’t it?  Looks like water, it even ripples when something touches it,”  She reaches in with her hand to stir the surface, and it ripples obediently.

“But it doesn’t pour out.”  Vanessa holds up her hand, and it’s missing three fingers.  “It also erases anything that crosses the surface.  Cool, right?  But it gets better.  Sticking with the water theme, you can wash the missing parts back into existence.

She gets up then, and lugs an old tin wash-tub into the view of the camera, sitting it on the other end of her mat.  It’s slightly awkward to carry when missing most of the fingers of one hand, and she sloshes a little water from it when she puts it down.  “Ooof.  Didn’t plan this part right.  Whoops.  Anyhow.”

Vanessa kneels behind the tub, and dips both her hands in.  Her left hand cascades water over the missing fingers of her right hand, and then she works them together.  As she does so, her stubby right fingers start to lengthen, and after barely enough time to get her hands properly clean, her fingers are back to normal.  “Ta da!  Imagine the fun you could have, heading off to a pool party short a few key parts.”

An artful lean over the Banisher’s Basin dips her ample chest inside, and when Vanessa sits up again, there are two large holes in her shirt.  If she still had breasts, they’d be peeking through, but as it stands there’s just plain pink skin in their place.  

“Now normally, going out like this does make it easier on the back, and a little harder on the ogling boys.  But the best part here is that a little dip in the pool...”  Vanessa sidles over, and repeats her motions with the water tub.  When she sits up, nothing appears to have changed.  Her chest is still flat and smooth.  But when she turns sideways, the viewers can see a slight curve.  “See?  The guys will wonder what’s up.  A little mystery to perk their curiosity, and to make them wonder just how big you’ll get...”

Vanessa leaves her breasts as simple swells, and shuffles back to the basin.  “Sadly, unlike more modern products, little attention was paid to the feel.”  She lifts her feet up, and slips both into the basin, then kicks her knees to show off the flat planes of flesh where her ankles used to be.  “Can’t feel anything at all.  No tingles, just one moment I had feet, and the next... nothing.”

Vanessa dips her legs in again, tilting the bowl so that her legs can slide in further.  When she lifts them away, her knees are bisected.  The fronts are still there, but a tapering cut has removed the backside of them.  She runs her hands over these new planes, and shrugs.  “I mean, I can feel the touch, but there’s no tingle, just... feels like I’m touching the back of my leg, really.  Doesn’t even feel like it’s inside my leg.  Seriously, what were they thinking?  On the plus side, I stubbed my toe while schlepping the water into the shot, and it stopped hurting the moment I put it in the basin.  So I can see how it would be a blessing for those with gout or arthritis.”

Vanessa rolls to the middle of the mat and does a few gymnastic moves, including a brief handstand, before returning to a seated pose.  She can no longer cross her legs, so they’re splayed in front of her instead.  “There’s one other little quirk I want to show you, but you have to ante up.”

She does some stretching and limbering exercises while listening to the jingling sound her app makes when donations come in.  As the number climbs higher, the stretches get a little more lewd, and she makes sure to show off her mostly-but-not-entirely absent breasts.  “There we go!  Time for the main act.”

Vanessa wriggles her way toward the basin once more and grips the sides.  She levers herself up over it, and plunges her legs and waist inside.  “Now for the tricky bit, sticking the dismount...”  As she lifts herself up, the viewers can see that she has been cut off just above the belly button.  She swings herself back and forth, exposing her smoothed-off underside.   Once the amplitude of her swinging is large enough, she pushes off with her hands, then snaps them forward to catch herself before her bottom hits the floor.  

Vanessa sets herself down on the cut-plane, and wipes her brow.  “Whew.  Made it.  That could have gone badly.  Unlike my favourite toys, this thing does not play nice with heads.  I tried it before the show.  Blind panic does not even begin to describe it.  None of this fancy ‘no need to breathe’ stuff.  I was suffocating, and barely able to think.”

A comment catches her eye, and she shakes her head.  “Tried that too.  Erasing just the back does mean you can breathe, but... eh, there’s nothing there to enjoy it with.  I mean, if you like your women limp and floppy...”  She giggles at some of the responses.  “Then maybe I’m not the right girl for you.”

Vanessa rolls to her back, lifting her hips into the air.  “Woo, doing a shoulder stand is so much easier with less weight.  You don’t have to take my word for it, check out the sonar-cam.  If they were just invisible, you’d be able to see them there...”  She wiggles her belly back and forth, twisting this way and that to make it clear there’s nothing to hide.

After her little show, Vanessa hops her way over to the water tub, and then repeats her dipping procedure.  She sloshes her hips around inside it vigorously, watching what is happening within.  Then she lifts clear.  The curves of her luscious rump have returned, as have broad but short stumps of legs.  However, her shorts are nowhere to be seen.  She settles back into the middle of the mat, giving everyone quite the show and grinning at the reactions.

“Some of you have figured it out.  Why didn’t the shorts come back?  Because there was nothing left to pour water over.  Anything that fully enters the basin?  It’s gone.  Completely and permanently.”

She smiles wickedly at the screen.  “So yeah, if I’d slipped, earlier?  Poof.  Now, none of you would like to see that, right?” she teases, grin growing wider.

“The higher the total goes, the further I’ll dip.”

The ringing sound of donations starts up once more, faster than before.

Vanessa hopped back over to the Banisher’s Basin, and clambered up above it like before.  She watched the total on the monitor, then swung her hips lower, brushing her leg-stubs through the surface, bringing up nothing but hips.  She wiggled those at the camera, swinging back and forth to show off.

For the next milestone, she winked at the crowd, and flexed her arms to dip her hips a little lower.  She sighed softly as she lifted them back up again.  “All the good bits gone...  Can’t even feel a tingle.  It’s weird, I was all hot and bothered earlier, but now it’s sort of... eh.”

She makes a show of dipping lower and lower each time.  Her bellybutton goes next, then the rest of her belly.  After erasing a few ribs, Vanessa frowns.  “Oh, that is a weird feeling.”  She wheezes for breath.  “No diaphragm any more, breathing’s a little tricky.”

She works her shoulders to expand her chest, her reduced breasts swelling softly as she does so.  “Hm.  Okay.  Good for one or two more, I think.  And you’re still pushing it up, goodie.”

Vanessa swings a little lower, and when she lifts up, everything below her breasts is gone.  “Oh,” she pants.  “Yeah.  Half my... lungs.  Gone.  Give me... a minute.”

Her worried panting slows after a bit, and her worried frown turns back to a smile as she notices the donation total.  “You guys.  Are you... sure?  Won’t be... able to... talk,” she gets out between little gasps for breath.  The ringing increases, and she bows her head.  “Last one.”

Vanessa dips even lower then, and then struggles to rise.  She’s little more than a head, with shoulders and arms.  She gives the camera a watery grin, then tries to sidle her way forward and off of the basin.  Her mouth opens in a gasp for breath that goes completely unheards.  For after all, she no longer has lungs...

Vanessa’s eyes go very wide, and she mouths a curse word.  Her next hand-step forward is her last, as her eyes roll back into her head and she topples.  Backward.  Two hands clutch at the edge of the basin, then the fingers go lax.  A moment later they slip out of sight.

A minute goes by.  Nothing.  Then a figure in janitor’s overalls enters the scene, carrying a mop.  “Tut tut, seventeen made quite the mess, didn’t she?  Can’t let this stay, or the floor will stain.”  The woman’s wearing a bandanna over her face, but the voice is familiar.

After she’s mopped up the spilled water, she turns to the screen, and drops the act.  “Hey.  Did the newbies get a scare?  Nobody tattled, right?”

Vanessa pulls off the bandana and the slouchy hat, then starts to strip out of the oversized overalls.  Underneath she’s wearing a bunched-up miniskirt, and a colourful, elegant blouse that looks much more expensive than the shirt that just vanished into the basin.  Her legs are bare, and she kicks off the sandals she was wearing.

On her neck is a plain black choker, without a number on it.

“So for those of you that are new... that was my seventeenth clone.  She made it three months before slipping up.  Or in, as the case may be.”  Vanessa crouches down beside the basin and tilts it up to show the camera.  There’s nothing left, not a finger, not a hair.  Vanessa-17 is gone.

Vanessa brushes the shimmering surface with a finger tip, and then studies it.  “Mh, no.  Not the best way to go.  I think Eleven still holds the record for loudest exit.  I may have to get that disintegrator back, some day...”  As she talks she walks to the other basin, and crouches there to wash her hand back to normal.

Vanessa sits between the tub and the basin, and pulls a knife from the hilt at her hip.  “So.  Time for number eighteen.  Top half or bottom?”  She pushes a button on the handle of the knife and it shimmers with eldritch power.  One half of the blade glows orange, the other purple.

She studies the screen, then nods.  “Cool, I haven’t grown out of my legs in a while.”  She turns the knife so the orange side of the blade faces down, then gets a look of careful concentration.  She slowly slides the blade across her belly, cutting herself neatly in half at the belly-button.  Once done, the seam starts to widen on its own, and she scrambles to turn the blade off and set it down before her top half tumbles backward off her legs.

Top-Vanessa quickly rights herself, and hand-walks to sit beside the other Vanessa’s legs.  Both are starting to grow at their division point, a tiny head and shoulders are peeking up from above the legs, while Top-Vanessa’s hips are starting to swell.

Once Leg-Vanessa’s head is formed enough to breathe, she grins at the camera.  In a squeaky voice she calls out, “Show’s not quite over yet.”  She waves to Top-Vanessa, and gestures her closer.  They kiss, both giggling at the difference in scale as Leg-Vanessa’s head is still smaller than her other half’s breasts.

Canoodling and fondling follows, aided by the fact that both halves are only half-dressed, and they put on as lascivious show as they can without further disrobing.  They’re not finished until long after they’re both full size once more.

The Vanessa whose top half is naked walks out of view then returns wearing a plain black choker and carrying a gold-tipped pen.  She gestures to the skirtless Vanessa, who kneels obediently while the number 18 is written on her choker, marking her as the clone. She puts it on, then fetches a craft pen, and soon Vanessa-18 has her number on her choker, marking her as the clone, and her ex-legs as the “original”.

“Thanks for watching, see you all next time.  Vanishing Vanessa out.”
