Girls, What do you think of this action when flirting with a guy?

This guy is tall, strong, confident, dominant and has a shaved head and a rugged beard and I want to flirt with him a bit. What do you think about this action where I can pretend I'm tying my hair and stretch back so my shirt goes up, showing a peek of my belly? Will that lead him on too much?
