costume party

[Hornylittlebugger]

I'm looking for a story, I can't seem to get the advanced search thing to pull up what I'm looking for. so, the story apparently won an of award for an event, and it begins with like this woman at a coffee shop, where she meets this vampire dude guy, who's like apparently hot enough for the lady to swoon enough over. the guy invites her to his house. At first, the woman's like really insecure about her costume choices or whatever, but her friend's like: "oh, you'll be fine." and then they go to the place and it's this giant... nordic, scandinavian palace mansion thing, where a bunch of people were having fun and getting horny and sexy with each other, and then eventually, some crazy sacrifice stuff happens in the mid way point, literally the protag woman's friends tits glow from the sacrificial sex thing that was happening, in which the main guy who invited the protag woman was like teasing her through out the entire thing, only for the end where the guy and her have like the best sex ever, and then it is revealed that all of that was to scare away a demon of some kind? and then he gives himself up to be a slave to the protag woman at the end??? this was probably the most wild summary I could give, but that's all I remember. if you find it, pls let me know.
