When Mistress Kat took her new slave, she told him there were to be no phones or anything used. She left him in the house for a few hours and he starting using a cell phone. When she snuck behind him, she saw it. After putting on her crushing high heels, she took the phone out of his hands. She put it on the floor and starting stepping on it, telling him that it will be his balls next if he tries it again.
