a/n: originally, this was rated R, but for many complicated reasons, I've edited it for content, so it is now pg 13. someday, I might post up the real story, full content. the only thing that is mine is the plot; the characters, polyjuice potion formula, etc, belong to j.k. rowling, unfortunately…

Draco stared uncertainly at the thick potion bubbling in his pewter cauldron. He was supposed to drink that? A large bubble forming on the surface popped in reply.

Sighing, he dipped his goblet into the cauldron. It emerged dripping with the dark brown concoction. Draco reached into his pocket and carefully withdrew a neatly folded linen handkerchief. He gently placed it on a nearby desk and gingerly unfolded it.

Nestled in the creases were a few short strands of black hair. He dangled one of them over his goblet for a moment before dropping it in. The hair shimmered against the murky potion before sinking. Thebrew frothed and immediately turned deep green.

Again Draco stared, still very dubious. He seriously doubted the wisdom in imbibing the potion now. It looked toxic.

Finally, in one decisive move, Draco drained his goblet, praying to every god he had heard of. He hoped he had done everything right.

It had been easy enough getting the ingredients, most of them were in the student store cupboard. As for the remaining materials, all he had to do was arrange a meeting with his favorite teacher and have Goyle "accidentally" set fire to the classroom outside Snape's office. He had had plenty of time to gather the bicorn powder and boomslang skin.

He was worried about the procedure. Did he add enough fluxweed? Was the lacewing boiled long enough? These questions, and a thousand more, swirled around his mind as he gulped the potion.

Letting his goblet shatter on the floor, he struggled to keep from vomiting. Seconds later, however, he was distracted by the burning sensation coursing through his body, as it reshaped itself. He was bent over on the floor when it finally stopped.

The Slytherin shakily stood up, gripping the desk as his legs wobbled. His vision was blurred and he waited a minute for it to straighten out before realization hit him, leaving him feeling very stupid.

Reaching in a different pocket, he pulled out a pair of round, black-rimmed glasses. They were an exact duplicate of the original pair, and he had gone to great lengths to obtain them.

With the glasses on, the fog in his eyes cleared. He turned to examine himself in the full-length mirror behind him. Harry gazed back at him. It had worked! Harry's face cracked into a grin.

Draco looked at his hands. They hadn't changed much. The fingers were still long and slender. He still had bony wrists. The main difference was that Draco was slightly paler. Only slightly.

Twisting in front of the mirror, Draco could see that the rest of Harry wasn't much different. He didn't have to change his robes, for Harry seemed to fit the smallest size also. Draco started to loosen his tie; it was the only item that displayed the Slytherin colors.

But something made him pause. Green seemed to suit Harry. Draco never noticed before (or if he did he had forgotten about it). The emerald color in Harry's eyes perfectly matched the tie. Draco stepped back to get a better overall look at himself.

Yes. Harry does look better in Slytherin's colors than in Gryffindor's, thought Draco. Ironic, since the boy is one of Slytherin house's greatest enemies.

But it didn't matter. Draco took off the tie and stuffed it in his pocket, where the glasses had been. Picking up the handkerchief, he shook the remaining strands into the still bubbling cauldron. Conjuring up a large flask, he then filled it with the gloppy green liquid.

"Evanesco." The remaining brew in the kettle vanished. He repaired the goblet on the floor with a different spell. He looked around to see if he missed anything else. Seeing that he didn't, he headed out the door to the dark corridor.

He was going to have some fun in this body. A few naked photos. Maybe a meeting with Weasle, but with a few… twists. Draco grinned wickedly.

As he casually paced towards the Great Hall, he thought about the leather dog collar at the bottom of his trunk. Draco wondered, how it would look on Harry?

Well he wouldn't have to wait long to find out.

a/n: well, that is it. for now anyways. if I get good reviews, I'll write a part II. (but good constructive criticism in small doses is good too )
