Lady Betty was pregnant and she did not want her boyfriend to go to other girls because of that. She had to find a way to control his sexuality. A little research told her that she could make him wear a chastity device so she did it. She hit the key and she made sure he only used his dick for sexual purposes when she was there and when it was with her.
Lady Betty felt that this loser was not as obedient as she wanted. She had to make sure he learned how to be obedient so she dominated him cruelly. She made him wear a chastity device and she teased him. She hid the key and she let him get hurt as she made him do what she wanted. The guy cried and begged her to forgive him but she did not.
