Bound and Suspended as His BDSM Sex Slave

My name is Sophie and sometimes I question my decisions. Strapped and secured. I have no where to go. I swing back and forward naked in the suspension. Awaiting the three knocks on the door. Awaiting my master to take me. Fully exposed and at his mercy, I take what I have asked for. Even if I changed my mind, my hands and feet are roped up in mid-air, my body swinging in its unprotected state. I hold my breath in anticipation.
Knock..... Knock..... Knock..................
