The massive thing fell to her hands and knees to lap up the blood stains on the floor. It thought there was no more of him left. She didn't know of the little, five millimeter spot on the ceiling near the dumbbell rack. The spot that held a drop of his blood, the only evidence Terrance Limpernoodle was ever in this room, mixed with Bruce's semen.
Satisfied that it had completed its work it started the final phase of its metamorphosis; taking the form that most pleased her this epoch. She rearranged her musculature to be more attractive to the human male, narrowing her waist and slightly flaring her hips, filling and raising her breasts on her chest, rounding her glutes, adding a layer of fat to soften and hide her astronomic might. The thing that called herself Keena observed her transformation in the wall mirrors. She licked the blood from her cheek with a tongue that was far too long to be human and smiled. She just had one more task to do to complete herself. She changed her multicolored mottled skin to a uniform dark chocolate color. Nodding to herself she ran her hands over her naked curves, pinching and pulling her nipples, stroking her clit, and relished the sensations cascading through her renewed nervous system. She rolled back her head and a moan escaped her lips. Being a human has some advantages.
After the erotic waves subsided Keena walked to the private gym's main door, her ample hips rolling seductively. When she reached the door she paused, listening for any indication someone was in the hallway. She heard nothing so she lifted the plates, two thousand five hundred pounds in each hand, and took them to the plate rack. She racked the plates in their proper spots, making sure that the stamped Madtown Gym logo was right side up and thought about her life and employees, former and new.
She had rejected the life her species had insisted she live; one of isolation and xenophobia. Instead she went out into the human world and blended in, hiding within herself. She made some mistakes and had many successes. She had failed with Terry, though. Now she had to expose her true nature to erase that failure. It only saddened her a little that she had to have him destroyed after what he did to her. She took an enormous risk disposing of that failure now. This new human, Bruce, intrigued her though. How does a mundane human become so powerful overnight?
She thought she knew the answer.
And she thought she knew who did it.
