She squeeze your balls

You feel your member getting rock hard and you don't react as the woman turns and sits on your chest with her face looking at your feet.

You feel her speaking - "Well...first I'm going to own your balls... grab a man testicles and squeeze them and he'll do whatever you want... you'll also beg me to enslave you if I want it..."

You feel her bending a few and then her fingers begin to caress your balls. You mumble a little feeling your erection grow harder then ever and then you feel her fingers cupping your balls... then the pressure begin to increase.. increase... and soon you start finding her grip painful.
