“Hey everyone, thanks for coming over.  Ready for something that’ll blow your mind?”

Terry grinned.  “You promised us an evening of magic.  And your father finds the coolest stuff.  What have you got this time?”

Rin grinned back.  “It’ll be way more fun if you find out the hard way.  Come on everyone, gather around in a circle.”

The group of friends shuffled around, loosely organizing themselves alternating boy and girl. Terry was to Rin’s right, followed by James, Katie, Alfred, Lauren, Oliver, and Sandy.

Once the group was arranged to her satisfaction, Rin set a small metal object in the middle of the circle.  Two doorknob-sized metal spheres formed the bulk of it, connected by a hefty rod a few inches long.

“That’s it?” asked Terry.  “A doorknob?”

“A magic doorknob,” clarified Rin.  She reached down and flicked it, starting it spinning.  It gradually slowed, then abruptly stopped with one knob pointed at Katie, the other at Sandy.  “Both of you pick it up.”

Katie grabbed for it first, and when Sandy’s hand closed around the other end the bar in the middle lit up bright blue.

“Hey!” protested Katie.  “I can’t let go!”

“See how the bar is timing down?” asked Rin.  The glow was shrinking toward the middle, slowly.  “It’ll let go when it goes out.  While it’s doing that, fix an image in your mind.  Some distinctive object.  But don’t tell anyone what it is.”

Katie and Sandy both frowned in concentration.  A few seconds later the bar in the middle flared brightly, as did the knob in Katie’s hand.  Katie released her end as the glow briefly enveloped her, but Sandy kept her grip.  “What was that?” cried Katie.

Rin giggled.  “Now you have to guess what object Sandy was thinking of.”

Katie tilted her head curiously.  “Why?”

“You’ve got a couple minutes to figure it out or else...”  Rin waggled her eyebrows.

“Or else what...”  Katie glanced down at her hand and squeaked.  “I’m turning shiny?  What is happening?”

“You’re turning into the object Sandy was thinking of.  If you’re quick about it, Sandy can use the knob to change you back... but only if you still have a hand.”

“I’ll be stuck?” wailed Katie.

“Just for tonight.  It wears off after eight hours.  At least, as long as nobody tries changing themselves by touching both ends at once.”

“This sucks!” groused Katie.  “Why me?  Why not her?”

Rin giggled again.  “That’s the best part!  You can’t tell which end is which.  Well, Sandy can for now, since she’s holding the master end.  That’s why she can change you back.  Or change anyone else foolish enough to grab the other handle.  But as soon as you set it down again, it’s random.  Ooh, too bad Katie, you’re out of hands.”

Katie stared down at her dwindling, transparent arms.  “I’m turning into glass?”

“Close,” agreed Sandy.  “But not quite.  C’mon, you can still talk, keep trying!”

Katie craned her neck to look at herself.  “Oh god, I’m round.  Cylindrical.  And my neck is getting thin.”  Her voice was getting a little squeaky, too.  “A bottle?  You’re turning me into a bottle?”

“Yay, you got it!” cheered Sandy.  “I was thinking this would be like spin the bottle, so... not very creative, sorry.  I’ll fill you with wine later, and drink from you.”

Katie’s head was dwindling, and her attempt to speak failed.  She flashed Sandy a half-hearted grin, then her lips curved into a circle and formed the mouth of the wine-bottle she’d become.

“This might be a short party,” grumbled Alfred.  “Six spins, and we’re down to one person.”

“Depends on how good you are at guessing,” retorted Sandy.  She set the doorknob down and gave it a flick to start it spinning again.  

It stopped with one knob facing Alfred, and the other clearly at Terry instead of between Terry and Sandy.  “Does it magically point at people, too?” asked Alfred.

Rin shrugged.  “Seems to.  If it didn’t, it’d take a long time to finish a spin, so I’m going to assume it was intentional.”

Alfred sighed and picked up the doorknob by the handle facing him.  He yelped when Terry grabbed the other end, locking his hand in place.  “Feels like I’m holding a strong magnet.  Weird.”

When the blue light flashed, it was Alfred that started to change.  He studied himself worriedly, and noticed that his arms were starting to dwindle.  “Something armless, of course.”

“No fun otherwise,” agreed Terry amiably.

Alfred tapped his chest, then opened his shirt to expose the glassy texture there.  “Cylindrical... oh come on, you can be more creative than that.  Another bottle.”

Terry’s grin broadened.  “Nope.”

Alfred started to look worried.  He glanced down at his feet, and saw they were turning to metal.  “I don’t get it.  Uh... an hourglass?”

“Oooh, nice one.  But no.”

“Some kind of science experiment?” asked Alfred desperately.

“Close, but you’ll need to be more specific,” agreed Terry.

“Uh...  I...”  Alfred tried to reach for his head, but his dwindling arm could no longer reach it.  “My head feels round and... large.  Oh my God.  You’re turning me into a Van de Graaf generator?”

“We have a winnah!” crowed Terry.  He offered the handle to Alfred, but when Alfred tried to reach for it his arm-stub just clanked against it and wouldn’t stick.  Alfred kept trying until his arms were entirely gone.

“Bother” was Alfred’s last word on the subject, before his head turned entirely to metal and his face faded away.

“Does he work?” asked Lauren, sitting beside the new machine.

“Flip the switch on his base,” encouraged Terry.  “It’d be cool if he did.”

Lauren did so, and the bands within the generator started to move.  She giggled, and stood up from her crouch to put her hands on Alfred’s “head”.  Soon electricity was crackling about her, making her long wavy hair start to rise in a great black halo around her head.  “Whee!  These things are the best.  Can I keep him like this?”

“Sadly, no,” said Rin.  “But you can have fun with your transformed boyfriend for eight hours.  Assuming you keep guessing right, anyway.”

Lauren fetched a chair so she could sit beside Alfred and keep one hand on his sparky globe.

The next spin paired Rin and Oliver.  Rin’s eyes went wide when the flash washed over her, and she started studying herself in earnest.  Her fingers squeaked as she rubbed them together.  “Some sort of rubber or silicone...  Mmm, feels nice.  Sorry, Terry, I think Oliver’s going to win me.”

Terry chuckled softly.  “Giving up so easily?”

“Didn’t know it could feel this gooood.  Ooh, my mouth is changing, feels all...”  Her head snapped back to stare at Oliver.  “You’re turning me into a sex doll?”

Oliver laughed and offered her the handle.  “I was curious.  You’d still have a hand, would you be able to change back if you were fully a doll?”

Rin licked her lips then moaned again.  She nodded slowly.  “Cool.  I’ll... wait.  God, this feels so good.  I’m gonna be a good toy!”  Glazing eyes peered at Oliver.  “Di’ you do... somthin?  Mind... oooh.”

Oliver shrugged.  “I wanted you to enjoy it.  Maybe I overdid it?  What do you say, Terry.  Should I turn your girl back, or do you want her like this?”

Terry smirked.  “The rules, such as they are, say we should make the attempt.”

To both their disappointment, the doorknob latched on to Rin’s silicone hand.  “So now what, I imagine her as Rin again?”

“I wouldn’t object if you added a few upgrades.”

Oliver’s smirk was still broadening as the doorknob flashed again.  He set it down, and watched with the others as Rin’s skin started to take on a more natural tone.  After a minute, she blinked at him.  “Oooh.  That was mean.”

“What?”

“Turning me back.”

Oliver glanced to Terry.  “Didn’t turn you all the way back.”

Rin studied herself.  The most obvious difference was that her clothes hadn’t reappeared, except for her panties.  The next most obvious change was that her breasts weren’t shrinking very quickly at all.  “Left me a wittle pressie?  Yay!”

Rin frowned.  “I feel... fuzzy.  Head is...”

Terry leaned over and blew in Rin’s ear, producing a whistling sound, and a squirmy giggle from Rin.  “Airhead.”

Rin tried to look insulted, then giggled.  “Do that again!”

While Terry was giving his girl a refill, Oliver spun the knob once more.

James and Sandy picked it up, and in moments, Sandy started to change.  Her arms and one leg started to dwindle, and she stared at her remaining leg in some confusion.  “You’re turning me into a hose?”

“Not as such, no.”

Sandy’s next few guesses weren’t any closer to the mark, and before long she toppled over as her head finished turning into a broad handle atop her cylindrical body.

Rin giggled and pointed.  “She’s a bicycle pump!  So you can fill me up better.  Yay!”

A few minutes later, Lauren guessed successfully that she was turning into a fishbowl, just barely in time to start changing back.  Shortly after that, Oliver slithered into a pile of playing cards, and was scooped up and shuffled by James.

Rin giggled merrily at the sight.  “Bet that felt good.”

James frowned, and abruptly set Oliver down.  He poked the doorknob, which picked out Lauren and Rin.  Before long, Rin was dwindling again, skin becoming silicone once more.  She refused to guess what she was turning into until her hands were gone.  Once she was “safe”, she said, “sex toy”, getting a nod from both Lauren and Terry.

Terry scooped her shrinking body up to much cooing and happy gurgling, before Rin finally went silent.  A large silicone breast sat in his hands, and he patted it tenderly.  “Nice work.”

Lauren smiled at him prettily.  “I’m sure you’ll both enjoy it.”

One more spin picked out Terry and James, leaving James to guess what the fabric crawling up his arms was for.  His first guess was a doll.  Once his hands started to dwindle he guessed terrycloth robe.

“Oooh, so close,” said Terry.

“Towel?” James tried, worriedly watching his hands.

“Even closer, but, no.  Washcloth,” answered Terry, as James’ hands disappeared.

James huffed in disappointment.  “That’s the same thing, just smaller.  No fair.”

“Maybe one of the girls will want a shower later.”

James glanced over at Lauren.  “Only one left...” he sighed with the remainder of his voice.

Lauren watched his diminishment avidly, then scooped up the little square of fabric.  “Can I keep him?  And my sparky generator?”

“Eight hours,” said Terry.  “Though Rin did say something about touching both ends affecting that...”

Lauren grabbed up the doorknob in both hands, then yelped as it flashed red instead of blue.  She dropped it again, and waved her hands.  “That stung!”

“Badly?” fretted Terry.  “We’ve got bandaids and such in the bathroom.”

Lauren blew on her hands a couple of times then shook her head.  “Nah, I’m fine.  It was more surprising than painful.  Do you think it stopped the clock?  That didn’t look like it was supposed to happen.”

Terry pointed at the square of fabric on the floor.  It was growing.  The others were beginning to change, too - the cards were shuffling amongst themselves, sorting themselves out.  The toy in Terry’s hand started to moan happily, distracting him from the rest of the changes.

Lauren sighed, and snuggled up to her static-generating boyfriend as he changed back.  Soon everyone was normal once more.

Rin pouted.  “Why’d you go and do that?  I was looking forward to...”  She licked her lips and winked at Terry.  “Maybe we can play privately later.”

“Lightning round?” asked Katie.  She scooped up the doorknob by one end, offering the other end around the circle.  “No guesses, just changes.  I’d like some sexy clothes to wear out dancing.”

“Quick word of caution,” said Rin as Sandy started to reach for it.  “The doorknob’s radius of influence is only about a block.  Big enough to cover you guys back in your apartments, but not if you go out.”

“But the manual revert will still work after eight hours?” asked Sandy.

“If you’re close enough, sure,” agreed Rin.  “But you know the rules of magic.  If you’re not back within a day...”

“Stuck for good, I know.”  Sandy grinned at Katie.  “I promise I’ll take good care of you.”  She grabbed the other end of the handle, and both girls chanted “panties” at each other until light flared around Sandy and she started to dwindle.

Katie kept her grip on the doorknob, and offered it around.  “I could use a bra to go with her.”

Oliver nodded slowly, and reached for the other end.  Soon he was dwindling as well.  Before he’d finished changing, Katie pointed the knob at James.  “One single guy left.  You’d make a sexy dress...”

James shared a long look with Rin, then nodded and turned back to Katie with a smile.  “You’re on.”

Katie squealed happily, and soon had a full collection - sleek black underthings, and a shiny vinyl dress that fit her like a glove.  “Don’t wait up,” she called cheerfully as she headed for the door.  “I might be very, very late.”

Rin rolled her eyes, and picked up the doorknob. “One more try, Terry?  I wanna be your toy.”

Terry grinned, and took the other end of it, but this time it was Terry that started to change into silicone.  Rin purred at what he was becoming. “Or this works too.”  She tossed the doorknob to Lauren.  “One more for the road?”

Lauren turned to her boyfriend, Alfred.  “What do you think, sparky?”

Alfred grinned, and accepted the challenge.  Lauren pouted as she started to dwindle.  Her breasts were changing in peculiar ways, going flatter and rounder, acquiring alternating bands of metal.  “Oh!” she exclaimed shortly before her head was consumed.  “One of those spinny generators.  This will be fun...”

Alfred gave her a quick spin once the change was complete, and was rewarded with a bright spark between the globes.  He put his hand in the way of the next spark, and grinned.   “Mmm.  Tingly.  This will be fun.”

“Are you spinning her breasts to charge it up?” asked Rin in fascination.

“Yep.”

“Lucky girl.”  Rin picked up the doorknob and set it back into the storage box.  “I don’t think I’ll be resetting Terry any time soon, but if you want her back before morning, give me a call.”

Alfred nodded, and picked up his sparky sweetie.  “We’re only two doors down, you sure she’ll change back?”

“Oh, very sure indeed.  See, the eight hour limit works no matter where you are.”

“But you told Katie that it wouldn’t!”

“I did not.  I let her assume that.  She’s going to have an interesting morning,” giggled Rin.  “Naked walk of shame time.”

Alfred shook his head, chuckling.  “You’re terrible.  Same time next week?”

“Yeah, I think we’ll be keeping this one.  G’night!”

Once the door closed, Rin darted back to her transformed boyfriend.  “Mmm, this will be fun.  I’ll be your toy tomorrow, even if we have to try a dozen times.”
