to sleep

"Seems like I don't really have a choice ..." I said, while i was lead to my cell. Sonya took off my handcuffs and I obediently lay down on the mattress.
Diane came in and I felt the steel clasp snap over my waist at the bed. "Hands to the back!" Sonya ordered. She pulled my wrists into two rercesses in the steel bracket and fixed them with wide leather straps. Next, Sonya and Diane tie my feet to a spreader bar and chained the bar the floor.

"I don't think I can sleep like this"

"Believe me, you will sleep." said Diane. At that moment, a transparent shell was pushed over the mattress and a loud hiss told me that a sleeping gas had been dispensed. Moments later, the world blurred before my eyes.
