As the sun began sinking in the early evening, the two youths ran through the gate behind the church into the cemetery. They slowed to a more sombre walking pace, as they passed tombstones varying in age from hundreds of years old to that year. The youths passed the last row of graves, and immediately saw that they were the last to arrive.
"You took your time", Seamus Finnigan said.
The other three boys were sprawled on the picnic rug that someone had thoughtfully brought along. Seamus sat restlessly, fidgeting every few seconds, and constantly changing position. Dean Thomas lay on his back watching the clouds zoom across the sky. Neville Longbottom was looking at a range of plant samples that he had apparently found among the graves. Harry Potter and Ron Weasley slumped down on the free space on the rug. Out of the basket he carried, Ron gave each person a pastry from his mother.
"She wouldn't let me leave without giving me all this food", he explained. "I tried to tell her I was an adult now, but she wouldn't listen!"
"It will be good for a midnight snack!" Dean commented, sitting up.
The five youths had shared a room in the Gryffindor tower at Hogwarts for six years. It had been a few years since they had all graduated, but they still managed to get together for a boys' night or something similar at least once a year. This year, Seamus had suggested a Halloween sleepover at the cemetery. None of the Gryffindors wanted to look like cowards, so they all readily agreed.
They set up two tents for them to sleep in, casting Muggle-repelling charms to maintain their privacy. As the sun finally dipped below the horizon, night settled in, bringing with it the cold. Seamus lit a fire, and the five school friends huddled around it, talking, telling stories and jokes, and drinking from the bottle of Firewhisky that seemed to have appeared out of nowhere.
By the time it was fully night, the only light sources their fire and the full moon that had peaked over the horizon not long before, they had moved on the ghost stories. Ron had a fair share of them, told to him by his older brothers. None of the boys were scared – or at least, they refused to admit they were. Ron was part way through a particularly scary story about a ghost and his missing skull when they heard a howl in the distance.
"Are there wolves here?" Neville asked.
"Not as far as I know", Seamus replied unconvincingly.
"There may be werewolves", Dean said, grinning.
Neville squeaked as another wolf howled, much closer this time. The youths huddled closer together, hoping for warmth from the fire, protection from the outside, or a combination of both. It was clear that all of them weren't too keen on wolves nearby.
As it neared midnight, Ron excused himself to urinate. He wandered among the tombstones, looking for a good place to pee. He paused, looking across the cemetery. The moon was partially covered by clouds. In its light, the tombstones looked like the black teeth of a monster, waiting to crush Ron in its maw. The moon winked down at Ron, seeming to flash orange. Ron shivered, and hurried on. A few meters away, next to a tombstone that looked particularly old, Ron found an old and gnarled tree. He let loose a stream of urine that steamed in the cold air.
"Merry All Hallows' Eve", a voice spoke out suddenly from behind him.
Ron spun around. One of the others, probably Seamus, was playing a joke on him. As expected, no one was there. Ron decided to play along.
"I hope you're having a good Halloween too", he replied.
"It's not so wise for someone so young to be in a cemetery on this night", the voice said, nearly cackling.
Ron didn't recognise it as any of the others. Who could it be?
"I've never been particularly wise, so people have told me", Ron retorted.
"Let me give you some wisdom, then", the voice continued. "All Hallows' Eve is based on the ancient festival of Samhain. Both are festivals commemorating the souls of the dead. Cemeteries are where the dead happen to congregate every year, for obvious reasons. One custom of Samhain was a sacrifice to… let's just call them the creatures of the night. Normally, it was just fruit or a chicken, but sometimes we liked a bit more."
The voice had taken on a frightening tone. Ron took a step back.
"Where do you think you're going", the voice asked.
As it spoke, a dark shadow materialised from behind the tombstone. Ron saw straight away that is was between him and their campsite. And he had stupidly left his wand back there! Ron took another step back as the shadow approached.
Then, the moon came out from behind a cloud, and Ron saw the being for the first time. The first thing he noticed was that the person was greenish grey. That made him uneasy. He couldn't think of anything that was green, except for merpeople, and he doubted this was a merman. The thing continued approaching Ron, exposing more of itself to the moonlight. Ron saw that its hair was patchy, and missing in large chunks. Its body was misshapen, and looked like it had been put together by a child. Ron noticed that the being was only wearing rags; the rest of its clothes seemed to have rotted away. As it got closer, Ron could now smell it. The stink was awful, like rotting meat. Ron gulped and took another step back. He now recognised this thing – it was a zombie. He had hoped never to see one in his life. Ron turned to run, but he was too late. The zombie grabbed him. For a rotting corpse, the zombie had a very strong grip. Ron tried to tell, but the zombie forced a hand over Ron's mouth. The smell made him gag.
"Let's make a quick deal", the zombie said, as if it were discussing the weather. "I want a sacrifice for this All Hallows' Eve. I haven't had one in decades. If you cooperate, you will probably survive. If you don't, I can't hold myself accountable for what might happen. And if you try to escape", he added as an afterthought, "I will catch you. Do you agree?"
With no other choice, Ron nodded. The zombie released his hand from Ron's mouth, but didn't release him. Ron took gulps of fresh air.
"Strip", the zombie said.
"What?" Ron asked, unable to believe what the zombie wanted him to do.
"I said, 'Strip'", the zombie repeated. He let go of Ron, but continued to keep a close eye on him.
Ron could see no other way for him to continue. He didn't doubt that the zombie could catch him if he tried to escape. Slowly, Ron took off his clothes. Soon, he was standing, shivering, only in his boxers. The zombie motioned for him to continue, and Ron reluctantly dropped his boxers as well. The zombie reached down and grabbed Ron's penis, jerking it a few times.
"Get hard", the zombie ordered.
Ron baulked, and tried to pull away, but the zombie's free hand reached to grab Ron's testicles. Slowly, the zombie began to squeeze. Very quickly, Ron gave in. The pain was excruciating. He thought of his fiancé, Hermione, and somehow, given the circumstances, managed to get an erection. As soon as he did, the zombie released Ron's testicles. Ron reached down to make sure his balls were still there, and sure enough, they seemed unscathed, though a bit tender. Meanwhile, the zombie continued to masturbate Ron. The persistent feeling of flesh on his penis was enough to stimulate Ron, and soon he was on the verge of cumming. As if the zombie had instinctively known he was close, the hand was removed.
Now, the zombie pushed down on Ron's shoulders until he was on his knees. When Ron attempted to get himself off, the zombie took Ron's hands and held them over his head. With its other hand, the zombie ripped away the fabric that was wrapped around its waist. A penis, and green-grey as the rest of the zombie, flopped out. It was at least 8 inches long. The zombie pushed its penis to Ron's lips. Ron refused to open them. He wasn't sucking this penis. The zombie reached up and pinched Ron's nose shut. Ron tried to hold his breath, but he could only do so for so long.
When Ron opened his mouth to breathe, the zombie struck. With lightning speed, it thrust its penis into Ron. It slid into Ron's mouth before he could prevent it. The zombie let go of Ron's hands and places both hands on either side of Ron's face. It slowly pushed Ron's face towards its crotch. The zombie's penis hit the back of Ron's throat, he gagged. But the zombie didn't let up. It continued forcing Ron onto its penis, until Ron's face was pressed against the zombie. The smell made him gag again. Now, the zombie began to thrust in and out, gaining speed as time went on. Before long, the zombie was slamming into Ron's mouth as hard as it could. Then, after a few minutes of pumping, the zombie released its seed into Ron's throat. Ron was surprised that it was a bit sweet.
"Thank you for that", the zombie said, and it let Ron slump on the ground. It picked up Ron's boxers from the ground. "If you don't mind", it continued, "I'll take these. My clothes are in no state to be used." Ron could only groan.
When Ron recovered sufficiently to sit up, he noticed that the zombie had vanished. He dressed and returned to their campsite. The fire had died down, and the others had all gone into their tents. Ron entered the tent he was sharing with Harry and Neville, and lay down to go to sleep. When it did come, Ron slept deeply and without dreaming.
