Domina Athena has had mercury in chastity for quite some time. After some nipple torture and flogging, she offers him his freedom, but warns him that freedom comes at a high price.
She removes the chastity device and begins to thoroughly work mercury over. She ties up his cock and balls, places clothespins on his junk, and then torments him with a whartenberg wheel.
Then Domina Athena canes the tip of his cock before swatting his cock and balls with an electric flyswatter, making mercury scream in agony. She hooks his cock up to a PES box with some conductive bands, and makes his body spasm in pain with the electrical current. Finally, she uses the violet wand on him before asking if the price of freedom is too much? Mercury begs to be put back in chastity, and for her to throw away the key.
