On the first left upper image you can see the beautiful morette that is going to use her left knee for ballbust the poor guy's balls.
On the right upper pic the blonde amazon has grabbed the slave's legs, opened them, and of course she is pressing her foot over the nuts. He is screaming and trying to join his legs, but she does not care.
On the third bottom left picture you can admire the young teen mistress that seats over the shoulder of Mario, who is immobilized at the ground with opened legs and she is very happy to beat him on his balls every now and then
Last image contains the same brunette of the first pic that after hitting several time the slave wants to give him the final blow on his nuts.
