How do you get a sweet, shy 19-year-old girl to open up and come out of her shell?

Sasha keeps her distance. Big brown eyes, soft mouth, a body that would look good in any frame. She owns up to being a rope-and-pain slut off-screen, yet this is the first time metal has touched her skin, the first time the camera will see her bound at all. We stretch her spread-eagle above the floor, feet and wrists locked high and wide. Every inch opens for us. At first she stays quiet, locked behind some private wall. The silence does not last. Nipple clamps bite down; we pull the chain taut to the metal frame so each twitch tugs them harder. She gasps when the flog lands across her spread cunt, cries out when the cane stripes the arches of her feet. The vibrator finds her wet slit next and never leaves it. Every time her hips jerk, the clamps pull again. She breaks. Shudders, swears, comes hard and loud, over and over, while the steel frame keeps every part of her exactly where we want it.
