Draco Malfoy smirked to himself as he was branded with the Dark Mark. His Master, his love had permanently branded him as his own. After all, love bites simply don't last. He rose and smiled to himself as he felt Voldemort's approval over their bond. Several months of training had brought the two together, and finally it was official. He would certainly reward his lover that night.
Draco Malfoy loitered around the entrance hall, talking with his friend Pansy and his two thugs Crabbe and Goyle, laughing over another joke as he spotted Potter walking out of the Great Hall, alone he noted. Nodding to the three of them he spoke loudly.
"I bet Potter didn't even survive the Killing Curse, after all, if he could do it anybody could. Instead the Dark Lord most likely took pity on such a pathetic wizard. He must be since the Mudblood and Weasel abandoned him for broom closets."
Pansy and Malfoy's thugs laughed accordingly. Harry stopped in his tracks and his eyes narrowed.
"Well Malfoy, if it's so easy then lets test it on you."
Malfoy stopped laughing and smirked.
"You're on Potter. Tonight after dinner on the Quidditch pitch, you'll cast the Killing Curse at me. I'll even write a magical contract to absolve you from any sort punishment."
Harry's eyes widened, but he thought it over and quickly came to a decision.
"You're on, Malfoy."
The two went to the library where Malfoy drew up the contract. Both of them signed the contract and glared hatefully at one another before making their ways to their respective common rooms.
Several hours later the entire population of the Hogwarts School of Witchcraft and Wizardry were in the stands of the Quidditch pitch. Harry sat in the Gryffindor locker room, drawing breath quickly at the knowledge that Malfoy would most likely die. However, having signed the contract, there was nothing he could do. He heard his name called and he proceeded onto the pitch where a grave looking Dumbledore waited in the center to officiate.
A hooded man kissed Malfoy's cheek and walked away, briskly scaling the stairs and taking a seat in the stands. Malfoy looked on arrogantly, apparently confident in the knowledge that he would survive. Dumbledore looked at Harry and he nodded. The old warlock nodded his head in return and looked at Malfoy who nodded as well.
Harry's eyes burned into his arch-nemesis' as they stared at one another from opposite positions. Dumbledore brought down his wand and Harry focused on all his anger and rage he'd ever felt for Malfoy and pointed his wand at him.
"Avada Kedavra!" Harry's voice rang out clearly, marred by rage and hate.
Malfoy appeared to get more confident as the beam of sickening green sped towards him. He held his ground, eyes flicking from Harry to the green beam. As it hit his eyes opened wide in fear and mouth opened in a silent scream. His limbs went limp and eyes dulled as he hit the ground with a dull thump.
There was a scream of pain and Harry turned to see the man from before obviously in intense agony. A sharp clap of heartbreaking thunder of a broken soulmate bond boomed around the silent pitch and the figure fell forward onto the ground.
Both Dumbledore and Harry ran to the man, looking on in shock as a glamor slid from his face, revealing the snakelike visage of Lord Voldemort.
Harry turned to Dumbledore, "Well, you always said I'd kill Voldemort with love, but I never could have fathomed this."
Dumbledore nodded mutely and patted his shoulder.
A/N: Ah, another ficlet for Abeo Voldemort. This one came to me as I was reading another story where Malfoy underestimates a pissed off Potter. If you didn't understand this one, Draco and Voldemort are gay lovers with a soulmate bond. When Harry kills Draco the bond snaps and kills him.
