Release under my heels slave

Description: The slave, as most of the time, is ready with his cock secured in the cockbox. he is sooo wanting to cum that mistress julia has emptied the content of an ashtray over his cock. the ash makes the soles of the lady feel like sanding paper. it is almost impossible to cum under them. yet she demands a cumshot from the slave. and yes with a few strokes under her soles the slave is hard and stiff. she can do anything she wants with his cock and he will still leak pre-cum. well the more he leaks the soaked her soles get. in the end she does what she loves - standing fullweight on the cock trampling the slave manhood until he cums.
