She's clearly in collusion with them. Escape!

She's a vampire now! How could you be so stupid as to forget she was there behind you the whole time? You attempt to dart forward, but Karen's soft embrace turns into a rough hold as she slams you back into the wall. Her strength is incredible, the air is completely knocked out of you and you are pretty sure you have broken a rib.
"Hey now. Not so fast. You can run off back to your leggy blonde soon, but you've got to help me out first, you are my manager after all." Karen's face is seraphic, every imperfection ironed out better than any plastic surgeon could ever dream of. Her hair is perfect, not the tousled mess you would expect from her rough treatment. The neckline of her torn dress hangs from the crook of her elbows presenting her perfect breasts which hold their shape without the use of her AWOL bra. Her crotch is once again obscured but her legs are muscular and long, ending in dainty, taloned feet. Her skin, like Gwen and Alex's, is deathly pale, the only hint of warm colour comes from the bloodstain on her chest and the subtle pink lipstick she always wears. Her canines look ever so sharp as she looms closer towards you.
"Now, considering how unprofessional you've just been, I'd like to make a formal complaint, perhaps even show you how you should really be treating your staff."
You try to respond, but you can barely stand let alone talk. She slides forwards, her knees gracefully parting your legs without tripping you. She nestles into you, hands on your chest, pressed groins holding you up against the wall. You can feel her labia through the fabric of your trousers, and it takes all you have to suppress your arousal. She places each of your hands on her firm, round buttocks, making sure to hike up her dress so that you can touch the bare, cool flesh. Your faces are mere centimetres away. She smiled sweetly and moves into kiss you, gently as if she was greeting a first time lover. You press your lips together, but she mushes her mouth against yours, and forces open your jaw with her improbably long and impossibly strong tongue. You definitely can't talk now as her tongue explores the inside of your mouth. Finally, she pulls back, opening her glowing green eyes.
"Hm. Very good. But not good enough. No. The lesson you need is more... drastic I think." Her eyes go from that of a sweet lover, to the cruel gaze of a hungry predator. Suddenly you feel spurred to action.
"No!" You yell as you move your hands around to the front of her waist and try to shove her back. Your efforts don't phase her in the slightest as she darts forward burying her fangs into you your neck. You try to scream but the pain is unbearable. Your hands swipe at her feebly as she writhes against you, drinking messily from your neck. Soon you can't help but feel aroused as you slide to the floor, this beautiful woman pressing her body against you. The pain slowly turns to pleasure, the fangs in your flesh and the lips on your neck points of severe ecstasy stronger even than the orgasm you feel erupting in your pants. And then, all too soon, It's over. You try to call out, to beg the beautiful creature for more, but the dark is taking you now.
