Your body is wracked with fear, just the sound of her deceptively sweet voice is enough to send the chills running down your spine and all the way back up again. And it wasn't just her voice you could hear any more. Her long, sleek legs are carrying her perfect body towards you at some pace, the rhythmic drumming of her cork-soled wedge shoes almost keeping up with the rate of your heartbeat. She is within twenty feet of you now, cornered under the computer desk. Still, you are unable to move.
"you've actually given up now, have you, Tez?"
you've always hated abbreviations to your name. there isn't, you figure, any way to shorten terrance, except for terry. and you couldn't be called terry since one of the far more popular guys has claimed it as his own.
You can hear her footsteps slowing down, assuming you had submitted to her intimidation.
"oh good, I won't have to expend any more energy chasing you!" resuming her usual tone of voice.
"Now can I reap the benefits? i'd appreciate your contribution, I'm almost a double-'D' cup now"
Just recently you'd started to become interested in girls, your computer skills enabling you to disguise the fact from your judgemental mother. Some of the girls looked a little like Mary Ann- her long legs, shapely hips and ample chest, but despite her being 'anatomically perfect' you had no intention of becoming an 'extra' piece of breast tissue or muscle on her beautifully supple, taught abdomen.
She began to walk again, slowly and seductively this time, appearing to accept your submission
"I knew this was what you want"

Now was your time for action. She was less than ten feet away now, almost within striking range; she was renowned for literally leaping onto her prey and restraining them under the weight of her developed body.
Your swift turn of speed surprizes both you and Mary, as you launch yourself from under the desk across the room towards the light of the open door. However, she doesn't give chase. not this time. she'd expected you to do exactly this, and she'd prepared.
