As Jeff set the controls for yet another change to his sister, that gnawing feeling that he was going out-of-control with the Chronivac was growing stronger, especially when he considered what he was about to do to her.
He watched as Emily, his suddenly older sister, finished her glass of milk and set it down in the sink.
Now, he thought to himself. Do it now.
He activated the remote and watched.
Emily looked like she was about to walk away, when, suddenly, she paused with a look of confusion on her face. Her hands shot up to her B-cup breasts as she grimaced in pain.
