Custom video. Mistress Katya enters the room expecting to find her sub waiting for her, but no one is there. Soon the POV sneaks up behind her and hits her on the head, knocking her out. Katya twitches on the ground for a little, before she gets up. When she gets up, she looks around, but again, no one is there. Soon the POV sneaks up on her again and knocks her out again. Katya lies on the floor and twitches, her eyes rolled up.
