There are many ways to make a girl weak in the knees. For Makenzie it meant a pair of leg cuffs and a crotch rope connected to them keeping her knees bent. Unable to stand straight it's only a matter of time before something begins to tire. A girl in this situation has few options. Stand tall and dig her crotch rope in deep. Go slack and hang uncomfortably by her wrists. Makenzie seemed to prefer the third option. Stand with her knees bent and try to find a comfortable spot that will never come. She can't even control the seemingly endless drool coming from her latex ring gag onto her chin and breasts. All the while the burning in her thighs grows.
