In this video, Mistress Lexi shows Nikki Domino the ropes of being a ballbuster. Lexi shows how to do it, giving several tough shots and running kicks for the slave. Nikki laughs at the pain of the slave. Nikki then joins the fray and soon delivers running kicks. Although the slave tries to get out of the pain, the Mistresses force him into a tight position between two columns. He is unable to move before his boots smash into his legs. He suffers more and the Mistresses make fun of him. He is finished by Lexi and Nikki delivering kicks to the head and the back simultaneously. Nikki finds it so enjoyable that she kicks him from the back just as he thinks it’s over. This makes both Mistresses giggle even more.
