Sometimes you have to take the good with the bad. In Savannah's case there would be no orgasms until she was good and tied. Once she was bound, her wrists tied to her crotch rope causing every squirm and struggle to rev her engine. Never one to make it easy on my subs I suspended a magic wand in fingertip range her to strain to reach it. Desperate to cum she manages to grab it and flicks it on high. Savannah's in heaven as the wand buzzes away; at least until she loses her grip and it bounces out of range!
