For being pretty much the perfect woman without letting on whether you like me too

Amy sticks out her lip poutingly. "Well if your idea of the perfect woman keeps a bit of mystery about her, that's hardly my fault" she says. She unzips her jeans and slides them around her ankles, revealing nothing but a few freckles and her natural red curls.

"Don't be getting any ideas!" she says as she shuffles over to you. "I just forgot to wear underwear today. It being your birthday has nothing to do with it!"

She lays across your lap, her beautiful white buttocks raised towards you. You notice that despite her tough talk, she's trembling a little - she must be nervous.
