Mistress Amanda wanted to find out whether her slave took instructions and followed them. She asked him to jerk off according to her instructions. She the watched closely to see what he would do. She did not threaten him. Once she had found what she was looking for, she increased the pressure and threatened to trample him with her high heels. She also watched closely how he would react to that and she compared the two.
Lady Absinthia loves her feet and she enjoys pampering them. She wanted her slave to do so for her today. He was new and did not know that when she asked him to do it, she was not requesting but it was a polite way to order him. When he refused to rub her feet, she made him lick them and smell them as punishment before he rubbed them as she wanted.
Goddess Nika did not like her slave that much. She wanted him to be taught a lesson so she used her boots to do it. She had the slave lie down and she trampled him as cruelly as she could. She stomped on him and made him endure the pain and he had no option but to endure it. When she was done with him, she knew he would never piss her off again.
