Yvette teaches her slave a lesson of the power of her legs
She jumps on him in a high schoolgirlpin on his throat, squeezing his windpipe under her weight, then she embrace his throat with her strong legs.
Now he's trapped in a proper headscissor and he realizes, that he has to fight against....
But it's to late, he cannot get free from the prison of her legs, he's to weak and they are to strong.
He gives his best, but after some minutes he's totaly exhausted...
Yvette can celebrate her victory..... not without some painfull steps and a final jump on his worthless body.
