Mistress Coco wanted to test how strong her slave's balls were. So she stripped her slave and she had him put some weights on his nuts. The weights were attached to a string which was tied his nuts. The guy felt excruciating pain but he tried his best to endure the pain. He was forbidden from crying and he had to take all that pain as a man despite the fact that he felt like screaming.
Mistress Coco did not like what she had learned about this loser. She had learned that he was a spy and she wanted to find out who he was spying for and what he had gathered so far. With the help of her friend, they brutally forced the information out of him. They did not bother with things like slaps. They undressed him and tied his balls painfully before they poured hot wax on the head of his penis. They also inserted a thin wire in his pee hole before making him lick the soles of their boots.
Mistress Coco wanted to test her new slave. She likes to give them impossible tasks because it taught them that she was someone who demanded a lot from them and they had to be on their best behavior and on top of their game if they wanted to be in good books with her. She made this guy carry a heavy load using only his balls. He tried for a few meters and he screamed in pain.
Mistress Coco caught this guy spying on her and she showed him what she did to spies. She forced the guy to strip naked and she crushed his balls using her high heels. She kicked him cruelly and she forced him to endure the pain. She did not care what he felt. All she cared about was that he had learned his lesson and learned it the hardest way possible.
