SpaceSyren - Spank Challenge

My hands are tied in front of me, and I'm wearing only my underwear. He sets a timer for 6 minutes. I go across his lap in a chair, with my elbows and feet touching the floor. Once over his lap, he pulls my panties down to around my knees. He then spanks me with a hairbrush, starting the timer when the first spank lands. The spanking is non-stop, with no pausing until the time is up. No matter how much I beg, he won't stop. Finally, the timer goes off and the spanking session is over. I stand up and the camera gets a close-up of my face, and then my bottom to show how red it is.
