Екстремальне подвійне домінування - боротьба ніг і домінування лизання дупи

Extremely cruel Dominas harrowing an innocent and poor slave by feet and asses. They push their bare feet deep into the slave's mouth, stifling her and laughing as they see her gagging and fighting for some oxygen against their feet. The slave has no chance against the dominas, she is just too weak to fight with their legs, and she gets a bit relieved when they push her face to the other's naked ass and commands her to lick it deep inside. The slave gets totally humiliated at every moment, and her chance for release is zero.
