You've paid your yearly visit to Doctor Bishop and during your exam she notices how stiff your cock is for her. She drops something and while bent over, your massive cock ends up between her big booty cheeks. She can't resist a big cock so she starts stripping and encouraging you to jerk off for her as she twerks and rubs her cheeks up and down on your dick Trying to stay as professional as possible, she doesn't fuck you, but she does suck you dry.
