(A/N: this isn't my best storey but I'm trying with exams and stuff, and I thought this idea was really cute)

Harry P.O.V.

"Are you sure we should be doing this?" Ron groaned nervously as he looked at the sludge unevenly spread between cups.

"Hermione has spent months working on this you can't back out now." I say

"But it's so weird!"

"We never said it wasn't Ron." Hermione tittered.

"But what if we are wrong and Malfoy isn't the Heir of Slytherin"

"Well then we are wrong. All evidence points to him." I groan

"Just drink the Polyjuice already." We all enter different stalls in the girls bathroom. I take off my clothes so they don't get ruined and replace them with the oversized Slytherin ones. I take a swig of Polyjuice potion and it tastes like goblins piss. Don't ask me how I know what goblin piss tastes like, it's a log storey. And I can feel my skin bubbling and my body stretching, and before I knew it my new body fit into the Slytherin robes and I stepped out of the cubical. Ron was next to me, or should I say Crabbe, and Hermione refused to leave the cubical.

A.N. I decided to leave this bit out because you all probably know all this from the movies/books

We are walking towards the dungeons, an unexpected place for the dorms for the "high and mighty" Slytherins.

"Pureblood." Malfoy says proudly to the portrait, and he goes in first, Ron and I following. The Slytherin common room was black and emerald, shining greens against pitch blacks, complementing the underwater view of the lake. I stared in amazement at the mermaid staring at me through the glass who decides she's wave, but before I could wave back Malfoy swatted my hand.

"Don't embarrass me imbecile. Crabbe I don't care what you do, but Goyle your coming with me... To our dorm room." He sneered. I followed him through a large black archway, that opened up to a sparkly green corridor with doors along the walls, apparently in Slytherin there are only two people to a dorm, and Goyle shared his with Malfoy, who locked the door and shoved a silencing spell on it.

"Now, now, Gregory, you know what you get when you embarrass me." He tuttured. I opened my eyes wide, scared of being hexed."and never telling me you had glasses, like Potters, now that really deserves punishment." I gulped, expecting the worst, but instead he pushed me to a bed and sat on my lap, tracing his fingers down my shirt, sending shivers up my spine. "Not speaking tonight huh? Well you'll be making some noise soon."

He kissed me, deep and strong and hard, he was trying to hurt me but it felt like heaven.
"Have you been cheating on me Goyle" he asked casually

"Huh what?" I was staring in disbelief at how much his features had changed tone despite still being sharp and ferret like.

"Because if that's what you are doing, keep it up, you have suddenly become an amazing kisser." My, I guess Goyle's, eyebrows shot up at the sinister undertone beneath the words, he said to cheat but his tone said that if he ever did he would be accustomed to more than one unforgivable curse. He trailed his fingers over my chest. No it's Goyles. I can't keep thinking of it being mine or this will be much much weirder than it already was. "Yesterday you didn't even know where to put your mouth, against my lips or my cheek or what? And suddenly you are... Well why don't I show you." He takes his hands and puts them on my - Goyles - hips and digs his fingers in, and just as I gasped in pain his mouth locked onto mine and his tongue explored. Sparks shot through my body and created a feeling I didn't know I could have, instinctively I wrapped my arms around his back and pull him on top of me, my left hand cradling his head, and my right gripping his ass. I felt teeth and tongue and heat swam my body, and I moved to kiss his neck and flipped us so his legs were wrapped around my body, I rocked into him, grinding our hips together, barely noticing the growing hardness of his body that I was never shown from Ginny, and I made my way down his neck, and nipped him hear and their, hopefully leaving marks in my wake, he pulled on my hair as he groaned and he froze, so I froze.
"What's wrong?" I ask

"P-P-P" I look down at myself I had transformed back into Harry during the make out, and I looked at him and remembered it was Malfoy.

"Fuck fuck fuck. This is your fault you know."

"MY fault!? I had no idea it was.. Was you"

"Well you knew I was a much better kisser... Then apparently Goyle. Who knew you would be enjoying the male fruit."

"I'm not gay! No you, you misunderstand. I just experiment."

"Sure you do." And I ran out while my body was still red, Slytherins staring at me, Harry Freaking Potter, running through their common room wearing Slytherin robes ten sizes too big.

"Bloody hell Harry, you look like you just fought in a war!"

"I might have Ron. Is Hermione alright?"

"I don't know, she still hasn't left the stall." I grab my glasses out of the pockets of the robes and put them back on, as I stripped out of the green lined robes and back into my red ones. "Did you learn anything?"

"A thing or two."

"Is Malfoy, you know.."

"Most definitely." 

"Oh wow he told you he's the heir!?"

"Oh wait sorry I was in a world of my own. No, we didn't talk much."

"What, did you do then."  I flushed red and looked away

"He just studied and kept telling me to keep my gob shut."

"Sounds like Malfoy alright, well I didn't learn anything other than Crabbe is supposed to be the head of this betting pool to figure out who the heir is."

"Well that's something."

"It's something alright."

As soon as I could I escaped to the Gryffindore common room. A group of three girls were walking up the stairs to their room giggling, and just on que as they were about to leave the stairway, Fred jumped onto the bottom stair and he and George laughed non stop as the stairs turned into a ramp and the girls tumbled down. Ginny was one of them, and I pulled her into my dorm. I pushed her onto my bed and she looked at me with those big blue eyes telling me she was happy.
"What came into you all of a sudden."

"Just shhhh." I whisper and clamp my lips to hers. She's so warm and strong beneath me but her chest digs into mine with a weird fierceness I don't really enjoy and her body doesn't fit into mine very well. But she is an amazing kisser and it feels good. But not as good as him. No Ginny. Keep my thoughts on Ginny. The way her small body bends into mine, leaving few gaps, the way her lip quivers with every move, the way her soft hair pulls through my fingers, her smell, sweat and dirt from Quiddich but it's not a bad smell... Malfoy smelt better almost intoxicating, he still smelt like sweat but also of parchment and ink, keeping a perfect balance between strong and soft on his neck, and his neck tasted only of sweat and skin but it was soft yet when stretched out all the way it had the perfect places for me to nuzzle into with my nose as my mouth explored his... NO GINNY. I jump off her just as I started getting hard, she had hickeys along her neck and she was panting but smiling.

"Seriously what has gotten, into, yoou!"

"Just a little"

"A little prick." I jumped and looked at her, how could she know about Malfoy?

"How did you...."

"I can see it. In your pants." I looked down and instantly covered my crotch blushing. She wasn't the one who made me... You know. "I'm just gonna go back to bed so you can..."

"Oh, oh thanks I guess. G-good night Ginny."

"Good night Harry." She blew me a kiss and I have never been so guilty in my life.

"Harry, did you hear the rumour?" Colin "Creepy" whispered in my ear.

"What Colin?" I groaned I wasn't in the mood for this.

"Apparently everyone is saying that Draco Malfoy and your girlfriend hooked up." At this I instantly looked away from my mashed potatoes and looked in his eyes.

"Why would people think that?"

"They both came into the great hall covered in hickeys, Malfoy looking distraught and Ginny beaming. We think it's because the Prince of Slytherin couldn't keep away from the best looking Gryffindor."

"Well the students can stop bickering. I am the one who produced those hickeys."

"Whose?"

"Whose do you think flashy?" I growled at him. He would never know I did both. I wanted to talk to Malfoy but there is no way he'd let me even get close to him, especially now.

_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\

"Malfoy." I sat next to him during potions and his neck turned red. He continued to completely ignore me. The lessen is almost over and he is still completely ignoring me!! "Malfoy!"

"Mr Potter. If you could refrain from speaking in my classes." Snape droned.

We packed up and I grabbed his arm. "Malfoy we need to talk." He just shrugged me off an sneered.

"I will talk when I know what I need to talk about. For now, never talk to me again."

_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\

Three months... Three months and nothing. He ignores me and I have sloppy make out sessions with Ginny whenever I think about him too much, but it's never the same. I just want Malfoy. Malfoy, Malfoy, Malfoy, did he know it was me and not Goyle and plagued me with himself? I'm so focused on Malfoy I can barely think about Colin Creevy and the others who were petrified recently. I can't even think of the Heir of Slytherin, who Ron insists is, Malfoy. My thoughts always go back to him, the feel of his mouth on mine, the way his body and mine fit like two puzzle pieces, even if it wasn't for very long, the way he still had sharp features but they showed hunger instead of hatred towards me, if only for less then an hour. No I need to stop.

Ginny grabbed me this time, pushing me onto the couch.
"This could be more fun in the dorm rooms you know."

"But I don't wanna walk there." So I picked her up, and took her to my bed to keep ourselves in private. Instantly she flipped us and pushed me onto the bed, suddenly stronger then ever before. She pulled our heads together almost violently but only touched our lips slightly. She ripped my shirt of and studied me, as if she had never seen my body before, tracing her fingers delicately around my stomach and my chest, and before I could do or say anything her lips locked with my neck and pushed me down. Kissing everything, everywhere. It reminded me so much of what I did to Malfoy.... The familiar Sparks shot through my body as she kissed my lips and pushed my hair out of my face, taking my glasses off and throwing them to the ground. Ginny never did this.
"Malfoy?" I whispered as he was on my neck. And he froze. I knew it.

"Why would you say his name when your KISSING me? You hate that prick."

"I know it's you Malfoy." His eyes opened wide and I flipped him. "I just wish you were in your own body." He shot daggers at me, but in a way Ginny would never be able to. Definitely Malfoy. I wrapped his legs around me and kissed him. Kissed him and kissed him and kissed him. And he kissed back twice as hard, when this was over I was sure my mouth would bleed. He tried to put his hands down my pants. "Not in her body Malfoy, that would be wrong."

"And this isn't?" He kissed my face between the words.

"This is something Ginny and I do everyday, just not the dirty stuff." He froze and I instantly regretted it.

"You are cheating on her with me." He sneered, obviously trying to hide his real feelings.

"More like, for three months I haven't been able to stop thinking about you and how wrong it is, and Ginny was a way for me to channel my emotions."

"So you used her." He smiled a cold smile "how very Slytherin of you."

"And you changed into her so you could get some of this. How very Gryffindor of you." He grimaced and I kissed him. His body changed back to his own under my body.

The second his body was his own I tore off his shirt, literally and he shoved his hand in my pants, the bliss of him on me was amazing and I....

"HARRY" a girl shrieked behind me.

"Ginny?"
