Note: I had to add this bit, because I thought of it while writing part 2. I originally thought of it as a stand alone one shot, but it fits. I apologize for the slight OOC of Draco, I know he shouldn't be so intimidated. This is Draco's POV.
Chapter 3: Harry stakes his claim
"You fucked Parkinson?"
Had I been anybody else, Harry's irate screech would have made me jump. I merely closed the book I was reading and stood up. "No, I did not fuck Parkinson. She blew me."
Harry's face was purple with rage. "So it is true! What the fuck, Draco?"
"Harry, she blew me. It's not like I asked her to marry me."
"But you- and I- an" He was speechless.
"We never made an agreement to be exclusive, Harry. She got down on her knees and blew me in the common room. She trapped me." I don't know why I was explaining myself. It was the look on his face, I decided. Angry, confused, jealous.
"Why did you let her?" He looked hurt.
I scrambled for an answer. "Who's gonna turn down a blowjob, Harry? You?"
He seemed to regain his fight. "That's not the point, Draco. You cheated, you were unfaithful, even if it wasn't your idea."
"Unfaithful?" I laughed, despite myself. "Harry, you've never once asked me to be monogamous with you. You've never staked your claim. You can't just expect me to read your mind and follow some, unwritten rules you've created for this… thing we've got going on."
"Thing? You call this a thing?"
"Harry, get a grip. We have sex, and that's it. We've never been on a date, never once talked about our feelings. Hell, we've never even spent the entire night together!" I was beginning to feel slightly indignant. "If all you want me for is sex, how the hell do you expect me to be faithful to you?"
Harry recoiled like I hit him. "That's all you think this is?"
"You've never said otherwise."
His expression changed, and I took an awkward step back. He kept advancing until I could feel his breath on my face, his magic radiating from him in waves. His eyes were hungry, possessive.
"I'm saying it now, Draco." He reached out and took my face in both hands. "You're mine. No one else gets to touch you."
"Yeah?" I challenged. It may not have been the smartest idea, but I did it anyway. "Prove it."
He was suddenly flush against me, pressing me back against the tree. His mouth went to my neck, his hands between us to palm me through my trousers.
"Does anyone else know how to turn you on, baby?" He growled in my ear, sending parks of lust rocketing to my groin. "Do they know how to touch you, tease you until you're screaming for more?" His hand was inside of my pants now, stroking me.
"N-no," I stuttered, gasping when his hand released my cock and moved, past my balls to "oh, god."
"Say it, Draco." He purred. "Tell me you're mine, that no one else will ever fuck you like I can." His fingers were teasing, circling my hole, but not penetrating.
"Yes, oh god." I panted. "I'm yours, forever yours. No one will ever…" He snaked one finger inside. It burned slightly without lubricant. "Harry, just please!"
Before I could blink, I was pressed face first into the bark, Harry yanking my trousers down to my knees. He pressed the tip of his cock to me, and I pressed back onto him. It burned, and I must have indicated so, because he paused when he was completely inside me. "Harry," I moaned, rocking back against him. "please," He complied, slamming into me, filling me, tearing me apart. I clutched at the tree, attempting to stay grounded.
It was over soon, we were both screaming our relief, coupled with professions of love and such, which of course I'll deny later. He collapsed against my back, wrapping me in his embrace.
"Mine," He whispered, kissing the back of my neck.
"Yours," I answered.
The next morning at breakfast, I was greeted with a large banner floating over the Slytherin table, the message sparkling in bright scarlet letters.
"Draco Malfoy is property of Harry James Potter. He is not to be touched."
