Mistress Gaia does not like to keep grudges. When her boyfriend pissed her off, she did not want to be mad at him for a long time and give him the silent treatment. She chose to spank him in the butt to express her displeasure at what he had done. She undressed him and spanked his naked butt for her punishment to be more effective. Her boyfriend got the message.
Mistress Gaia did not like the food that her slave had cooked. She had to make sure he made better food so she punished him. She bent him over and she whipped him as hard as she could. She humiliated the slave besides inflicting pain on him and by the time she was done with him, she knew he had understood what she wanted and would not repeat his mistake.
