Mrs. E wants to take the slave to levels he has never experienced before now that she knows she can apply full pressure to his cock on the cockboard.  So she orders the slave to take it like a man for her and  put his cock on the cockbox so that she can crush it real good.  The slave is still sore from the previous week shoejob but he has to obey otherwise things will not be good for him. The slave has no clue to what he is about to experiences as Mrs. E is wearing her mean but sexy tan pumps with ribbed soles from many other videos.  Plus, to be evenr meaner, she has walked all over the pool area hoping to catch enough sand grains on the soles so that it hurts as much as possible.  Imagine being done a shoejob with sandpaper soles :o  SHe starts by applying trampling the slave with her shoes so that he gets a taste of them and he does.  He knows what is coming aint good but he has to endure otherwise bad things will happen.  She stomps his cock and even grinds it and you can hear him moan a lot.  And soon enough those harsh soles are rubbing his cock taking him to excruciating pain but an immense pleasure as he cannot taste the difference between these two sensations as his cock is shredded apart under her soles.  Just when the slave is about to cum, Mrs. E takes control of his cum and presses him hard eliminating all that rush and soon enough his cock is flacid again.  She does it a couple of times until the slave can't take it anymore and his cock no longer erects.  She gets mad and removes him out of the cock box!!! Boy I want you to cum and you will cum one way or the other she says.  I need to stomp your little descendants so that you dont reproduce anymore and she continues stroking his cock real hard against his belly until he cant take it anymore and shoots a load. She is happy and walks away as if nothing has happened.
