Apartment 2127

I was in a new city and new school with no friends. Sexual frustration had been building as I was approaching 2 years since my last relationship had ended. In my first week of classes I had only managed to make 1 friend. Zoe, a girl I would casually talk to during Biology. Mostly she talked at me. She was a bit wild and would mostly talk about crazy or dumb things she had done. A lot of it was sexual and I didn't really have anything to add to a conversation like that. Before college I had always been a fairly conservative girl.
A bit of a tomboy growing up with 3 older brothers. And I would describe myself as nerdy since I read a lot, didn't really party, and played video games pretty frequently. About a week into class I got my first college party invite from Zoe. Well, I thought it would be a stereotypical college party, but it ended up being a gathering of 5 friends and myself. I freaked out a little leading up to the party just because I didn't know what to expect.
Who would be there? What would they be doing? What should I wear?
