Mistress Iside - Revolting foot-gagging

Today I really want to use my beautiful mouth-fucking foot, so good at filling and fucking the mouth of this dirty worm; for him it won't be easy to resist the urge to throw-up. Completely chained to my instrument, without any possibility to move, I will ensure that my foot goes down deep inside his throat; but, this time, I don't want to limit myself: I will push my foot so hard and deep, that this slave will make such a traumatic footgagging experience that, he will never be able to forget!!
