Please Don't Bite

"Chirs, you're acting weird" I backed up to the door as Christina sauntered towards me.
"Chris?" I fumbled with the door knob. It was locked. I glanced down to see there was no key…
Fudge.
"Chris, back off!" I half yelled.
"Connor, you don't know what it's like." Her eyes dancing "to feel so…hungry".
She came closer and closer until her hand rested on my neck.
"Chris! Get away from me" I said pushing her off with difficulty. Christina fell to the floor and bared her fangs.
I ran to her desk and rummaged around for the keys but couldn't find them.
Shit, shit, shit, shit… First time I'm alone with a girl in her bedroom and she tries to EAT me?
I felt her nails claw my shoulders and heard her laugh and my glasses were being taken off. I grabbed her lamp and swung around at her with it.
But she wasn't there, or maybe she was. I couldn't see clearly without my glasses. I ran to (what I guessed) was the window and tried to open it. It was locked.
"Help!" I shouted, hoping her foster sister would hear me.
Chris appeared behind me, reached up and pulled my hair.
"Ow, Chris. What the hell is wrong with you?"
"I'm just a little hungry, Con." She yanked harder on my hair as I collapsed onto her chair. She laughed sadistically and stared at my neck.
Before I knew it, I was on the floor, bleeding from my neck.

*********

Christina has been screwed up for most of her life. She's addicted to smoking and skips class. Her best friend Tristan is slowly moving away from her and she's finding herself more alone than ever. She manages to hatch a deal with smart boy, Connor to get her the grades she needs to get into to college and they end up sort of becoming acquaintances.
One night, Chris gets bitten. Her life is changed for good now, and though he doesn't know it, Connor is getting into some deep trouble.
