Day 5 for Beretta. Will she be the perfect slave?

Beretta's final test. She wants that Upper Floor slave mark, so she takes a crotch rope that bites hard and stacks weight right on her pussy. She holds. Blindfold on. Head in the dark. Every muscle tight, waiting for the next strike. She can't see it coming. She only feels the rope drag deeper and hears her own breath catch. Her thighs tremble. Her pussy aches. She stays still anyway. One wrong twitch and it all comes down on her. The question is simple now: can she keep her body locked, her mouth shut, her mind clear while the rope and the darkness do their work?
