Cock Massage with Bare Feet

With bare feet I play with my visitor's small penis. I rub him between my soles - kicking and squeezing him with my toes. Then I can get a better grip on him and can also move his foreskin a little. The guy seems to like it - as he's moaning and his cock is starting to drool. His glans is soaked with the precum which also wets my toes. I massage his cock more and more and also increase the pressure a little. What I don't want is for him to cum while playing with my feet. I have the impression that this will happen soon. I want the cum in my pussy and not on my feet. So massage the perineum and anus. Break.
