Hermione the Hex-Witch
"Now" she says, as she takes off her robe and lies down on the bed in front of you. "I've placed you under a hex. *laugh* You will bend to my will, whenever I demand you to be in a position like this, whenever I demand you to be horny for me, you will not be able to think of anyone but me. Sound fun? *snicker*"
You cannot believe her words.. Hermione has always been your best friend. You had no idea she had any romantic interest in you whatsoever... and yet...
You cannot tear your eyes away from her sexy figure. You begin to see her in a whole different light.
Then your brain begins to work again. You ask what you have to do to get yourself free.
"Oh thats easy," she says with a smile. "You will have one week to be my sex slave. After that, you will be free."
At this you begin to sweat. A sex slave? For one week?
"Haha, that look on your face is priceless. Most of the girls in Gryiffindor were just 'dying' to get you to bend to their will... But only I found out how to cast the spell!"
