480p. 30FPS.  Mistress Scarlett Morgan and Ebony Goddess NYX are standing in the garden with their slave and They need to warm up quickly as it is very cold outside.  They command the slave to lie down on the cold stone floor and use Their boots to trample and crush him. They soon realise the more They trample the warmer They become. They stomp harder, and faster and laugh at the slave who groans in despair.
