Ashley has an injury that is preventing her from playing netball and she needs to know how many sessions with you it is going to take to fix her back, you tell her 8 sessions and start getting her to stretch straight away. You tell her to bend over in her mini skirt and you get a great view of her ass, your cock instantly springs to life and when Ashley turns around and sees the bulge in your trousers she realizes why you want so many sessions with her. She decides to make you a deal, she will let you carry on looking up her skirt while you wank your big dick if you agree to give her all of the sessions for free.
