The freedom was exhilarating. Now that he didn't care what other people thought of him, Neville could do whatever he wanted. The solution, of course, had been Polyjuice, and he was surprised he hadn't thought of it before -- after the horror of Snape's NEWT Potions class, he could brew it in his sleep. He'd taken to carrying around a little silver flask of it in his pocket, just enough for a few hours. He wished he could keep dozens of different people's potions in his flask, but it couldn't be mixed, so he was stuck as a single person for as long as he was changed.

He pushed his glasses up his nose slightly and ran his fingers through his red hair. Tonight he was "dressed" as Ron's brother Percy, and it was time to go out for the evening. "Percy" was a regular in a certain wizarding district of London known for its discretion and the wide range of services offered, but there was one place he'd never been. LaBell's catered to more... exotic tastes, and its clientelle generally consisted of the very desperate and the very rich. He knew Bill Weasley worked there, since Bill's curse-breaking days were behind him (during the war, he'd been hit with a spell that rendered him nearly a Squib), Neville wondered exactly what he did at LaBell's.

Neville apparated to the doorstop, used the reflective surface of a window to adjust his robes and glasses, took a swallow of Polyjuice, and knocked on the door. It was opened by a statuesque black woman with absolutely no hair, who took his hat and cloak and ushered him into a side room without a word. She closed the door behind her as she departed, leaving Neville alone in the room.

Almost immediately, a curtain at the far end of the space slid back and there stood Katie Bell herself, in a low-cut dress and heels. "Percy!" she exclaimed, crossing to where Neville stood. "What can I do for you? I assume this isn't a business visit..."

Neville grinned. "Actually, I was hoping to see my brother. In a... businesslike fashion."

Katie's eyes went wide. "I... wow. Okay. I think that can be arranged. You've certainly come to the right place, though I never would have expected it from you!" She gave him a wicked grin and said "he'll be right down -- you sit yourself down and wait a minute," before vanishing behind the curtain again. * * *

Bill was completely dumbfounded. "Percy?" he said, his voice high with disbelief. "I might've understood Charlie, but Percy? He's so... wow. I don't know, Katie, I don't think I can do this."

"He's more my type than yours anyway, Bill. Just give me a little snip off the end of your hair." She grinned. "And strip." As Bill complied, Katie stripped herself and poured a single dose of Polyjuice from the portable cauldron in the corner. She dropped in Bill's hair, blew on the potion to cool it to a drinkable temperature, and downed it in one gulp.

The change was fairly quick -- her frame grew, her breasts receded, her long dark hair turned a coppery shade, and, in the part of the change she found most disconcerting, her vagina closed up and Bill's dick sprouted from the newly bare area between her legs. She grinned at her doppelgänger and snatched his clothes from his outstretched arms. Dressing quickly, she made her way back out to the room where Neville sat.

The sex was, to say the least, fairly incredible. The feeling of wrong-ness permeated the air and the tension just caused them to go at one another more ferociously. When Percy came in Bill's mouth and Bill swallowed, Percy groaned and was hard again almost instantly. When Bill licked a path up Percy's chest, flicking his tongue across his younger brother's nipple, they shared a momentary lapse of higher-brain function.

And then, just like that, an hour was nearly up, and Bill was hastily on his feet, stammering excuses and retreating just as Percy was doing the same thing -- back to his clothes, back to his flask, for Neville was sure he had only a few moments left. As Percy scrambled to find the silver flask, Bill paused in the doorway, amused by this behavior, until he realized what must be happening and his eyes bugged out. "You... you're not Percy!" Bill shouted, as Percy guiltily turned around, Polyjuice dribbling down his chin. "Who did I have sex with, then?!"

"A gentleman never betrays his secrets," Percy grinned, wiping his mouth with the end of his sleeve. "But I'd say you're about to." For he'd noticed "Bill's" hair darkening and his frame shortening -- not to mention two suspicious mounds forming around his chest. "Of course, you're not really a gentleman, are you... Katie?"

"But who are you?!" she pleaded, as Percy collected his things and exited the room. "Oh, bollocks."

Neville smiled to himself. Now that he knew LaBell's used Polyjuice, he'd have to patronize it more often. He could have anyone he wanted; anyone at all.
