This is Jayce's first time using the mystery substance before she perfected it in the mystery substance video. She is clad in a corset, stockings and matching bra with no panties and takes big, fluffy pussy pies to her lady parts and her ass in pure bliss She then takes out two buckets of slime she has made that were her first attempts to make the mystery substance in her latest video using it in all the colors. This is the substance before it was tweaked a bit to make it what it is today but still, looks incredible even in this state Very slimy, slow pouring just like the mystery substance, just a little bit different She is absolutely coated and sticky and covered in pies by the end! ))
