Mistress Enola felt that her slave needed to increase his pain threshold and so she trampled him with her sneakers. She did it on his balls so that it would be even more painful. She stomped on his dick and his balls and she watched him struggle not to cry and she made sure he did not cry or scream. And slowly, he started to harden like she wanted him to.
Mistress Enola did not want to have secrets in her relationship. She wanted their relationship to be open and that is why she chose to punish him and do it in a manner that he would not forget in a hurry. The mistress forced him to lie down and lick her sneakers which were dirty. He was scared and did as she ordered. But he also learned a lesson and did not keep any more secrets.
