I like to remind my footboy, that no matter what, I'm the one with the control over his balls . I always get the say so as to when he gets to cum and when he doesn't. I know it's hard when you have a perfect set of soles planted firmly on your cock, BUT, it's only on my say so when release is permitted. And He's pretty good at following my orders. I tell him he is to give me all he's got in his balls and that he is to cum all over my pink toes for me, and he delivers, on command.
