I've tried about FOUR different prologues but I think I've finally got it.

PROLOGUE: TOO LATE

                        Her kiss on his neck sent reassuring warmth down his spine, quelling the shiver of fear. Jean relished in her warmth as she pressed against his back and her sweet breath as she whispered in his ear. She urged him to keep going, urged him to not to stop. Eager to please her Jean kept his pace, his heart hammering in his ears.
        He kept going despite the screams, the howls and the blood.
        Thundering along beside him were his brothers, her other lovers, just as determined to satisfy her as he was. And because he was clearly her favorite they ran even harder, hoping to race their way into her heart.
        As if she had one…
        The corridor took a sharp turn and one of his brothers slipped trying, foolishly, to negotiate the twist in his blood slick sneakers. Jean leapt over him easily and continued up the hall, receiving a sweet kiss on the nape of his nape for his effort. He pumped his legs even harder with joy etched across his face in a mean grin. The others fell behind as he accelerated. He was first…in everything.
        The corridor opened up a bit into a small but lavish lounge set before a huge wooden door. They were almost there, Jean knew, and his excitement increased even more. He flew through the lounge kicking aside the small furnishings blocking their path and grabbed a hold of the huge ornate handle set right in the middle of the door. The heavy handle lifted easily enough with a loud click.
        But just before Jean threw his shoulder into the door she hissed into his ear and dug her nails into his shoulders. Immediately he obeyed with his hand still on the handle but the huge door had begun to open a bit on its well oiled hinges. It was too dark inside the room beyond for him to see anything. The smell like thick burning wood and copper rushed out at them. Jean was sure he could hear someone…or something… breathing just on the other side of the door. With a caress that was almost sweet she pulled him back away from the door. Too late, she whispered into his ear, they were too late.
        Finally catching up, his brothers tore through the lounge behind them. That she gave them no warning was further proof that he was her First. Even as she pulled him back away from the door she let them rush on through and into the room.
        After they rammed their way in the heavy door swung back and nearly closed. Jean heard them begin to rip the room apart in their search for it. He drew a shuddering breath in anticipation; would they soon have it?
        There came a bellow of a growl, so loud and deep that it vibrated through the door, across the floor and right up his body. His brothers screamed. Not the powerful, joyous screams that they had been shouting earlier. Now they were screaming in terror.
        Jean heard a loud, horrid, tearing…crunching sound and one of his brothers screams were silenced. The sound of the others footsteps rushed back to the door. Jean saw the bloody hand reach through the narrow opening, saw his brothers terror filled face as he tried to escape. But something large moved through the room after him, its footsteps louder, heavier…quicker. His brother managed to get halfway out of the door before something caught him from behind.
        His brother screamed for help as he fought to free himself although Jean could not hear him and no longer saw his pleading eyes or blood streaked face.
        Jeans eyes were focused deep into the dark room, beyond his brother, on a pair of huge gleaming yellow eyes and his ears were filled with the warning his Mistress was screaming;
        RUN!
