Harry had bought the machine off the Muggle website eBay. He had decided he would tell Draco he had bought the contraption at a magical flea market last weekend with Hermione, which was slightly better but not much. And Harry knew that bewitching the thing probably broke a few laws but for the sake of peace and the sake of delicious, delicious candy floss, he decided he could risk it.
Draco came home that evening to find Harry standing over a machine spinning round like a top, full of wispy pink clouds. Draco's eyes grew wide as he shrugged off his coat and laid it over a bar stool. "My God, Potter! What's all this!" He hoped it wasn't some strange concoction Harry had whipped up; Lord knew neither of them were much for Potions.
Harry blinked. "It's...it's candy floss." Draco stared back, uncomprehending. Harry sometimes wondered how Draco found him way home every night. "You know, spun sugar."
Draco nodded. "Ah, I see. I'm going to have a bath before dinner. You did make dinner, didn't you, Potter?"
Harry rolled his eyes at Draco's retreating figure. But his eyeroll was quickly replaced by a look of panic. He had been so engrossed in his candy floss, he had completely forgotten about dinner.
Draco sank down into a nice bath - bubbles, tiny toy boat, the works. Today had not been a particularly stressful one; far from it, really. But he liked to believe it had been, so as to enjoy his bath more. "Ahhh," he sighed, lather coating his chin and ears. "This is nice." He sniffed the air, seeing if he could make out what might be for dinner but all he could smell was soap.
"Aaaaaarghhhhh!"
Draco slipped under the water in surprise and came up spluttering. What on earth - ?
"Malfoy! For the love of God, Malfoy, help - aaaarghhhh!"
Draco leapt from the bath and reached for his towel as quickly as he could. His dinner was in trouble! "Potter!" he screeched as he slid into the kitchen, wand out. "Potter, what is going - "
Harry had his hand in the candy floss machine, up to his elbow. Flecks of blood splattered the counter. "Malfoy, I think - I think something went wrong with the spell - " Harry choked out.
"What? What spell? What are you talking about?"
"Never mind that! Help me, it's eating my arm - aaaaarghhh!" Harry slammed against the counter as the rest of his arm was consumed.
The sheer absurdity of the situation left Draco's mind a blank. What did you do when your boyfriend's arm was being eaten by a candy floss machine? This was definitely not covered by any class at Hogwarts, as far as he knew.
"A...accio!" Draco screamed out, the first spell he could think of.
"No, you idiot!" screeched Harry, as the candy floss machine spat out the mangled remains of his arm and went zooming towards Draco. "Don't call it to you!"
The candy floss hit Draco square in the chest, sending him tumbling backwards over a sofa. Harry held a dish towel to his bleeding stump, managing to make it into the living room in time to see the candy floss machine eating its way through Draco's chest. A look of shock was affixed permanently to Draco's whitened face.
Harry sunk to the floor, feeling very faint. A sob wracked his weak body as the world went black. In the last moments of consciousness, he felt himself raise his own wand and call the machine over to finish its job.
