Sissy in extreem bondage

The slut was ordered to the mistress for even more harsh training. That this ends up very bad for the slut in bondage, mercilessly at the mercy of the sadism of the mistress, had probably not expected the Sissy. At the latest when she hovers completely defenseless free in the room, completely tubed and the environment reduced to the small windows of the gas mask and then perceives the mistress just ingenuously even the whip unpacks knows the slut this will be an extremely hard training for her.
