You hesitate.

You hesitate for a moment unsure of what to do, but it's too late. Keira takes the opportunity to shove you through the door with both arms. You stumble on the step and try to spin around, but she has already slammed the door in your face. You hammer at the little window as she locks the door, then turns to you with a sad smile. Linus charges up behind her, shoving your friend violently aside. His face, filled with anger, covers the window, and he yells soundlessly, his terrible fangs flashing. His yells abate, and you watch with horror as he turns to Keira with a grim smile. His movements are hidden for a moment, then suddenly he thrusts her face against the door. She has her arms either side of the window so you have a clear view of her flushed face. You see her eyes scrunched up in pleasure as her body shudders with each of Linus' thrusts. Hot tears roll down your cheek as she arcs her head back, a soundless moan of pleasure escaping her lips. Then Linus darts down with his mouth, his fangs sinking into Keira's neck, a little dribble of her crimson blood trickling down to her collar. You weep as her face grows pale, her shocked expression warping into a twisted smile as her fangs elongate. Her unnaturally long tongue lolls out in pleasure. Before long, Linus ceases his thrusts and reaches around to kiss Keira daintily on the lips, turning her now perfect face slightly. This seems to bring her back to consciousness as she pecks lightly back. Then she fixes her glowing golden eyes on you and licks her lips hungrily. You see her turn to your former lover, but you are already backing away, breaking into a run. You wish the night would end, now more than ever.
