[Looking for Two Fics, Please Help!]

I'm looking for two different stories. One of them is a one shot. Draco is a vampire, but everyone thinks he's dead. Harry meets him in a dark alley, and Draco and he have sex against a wall. Harry's the bottom, and a virgin. Um... At the end, Draco insists, and Harry agrees, that Harry is Draco's. I'm relatively sure the story is archived on Hex Files, but I can't seem to find it. Help?

As to the second... it's a chaptered story, but I don't think it was archived on Hex Files. I'm not even sure what the pairing was. I know the story was complete though. Snape is the head of house for both Gryffindor and Slytherin, and they share a common room. This results in a huge fight in the common room, during which Harry comes in and disarms everyone (or accios all their wands, I can't remember) wandlessly. They end up in a huge pile, and everyone is a bit stunned. Hermione and Ron are the prefects and, as a result of this incident, Ron ends up getting stripped of his prefect status, and Harry gets the post instead. Ron tries to poison Harry with poison on the pin part of his prefect's badge... Um... that's all I've got. I think it's all in one story, and if someone could find it, I would owe you a serious debt. I've been looking for the story for ages!

The first one is called Yours by Spae at spae.livejournal.com/5428.html. It is one of my favorites. I hope this helps. The second one I don't know.... Sorry!
