This slave is most fortunate today, with four feet entirely at his disposal. Mistress Gaia and I are determined to drain the balls of this insignificant creature, but only because we wish to indulge in a bit of ballbusting afterward. This pitiful little appendage is as soft as a worm, and we are almost tempted to impale it with our heels, but then we remove our shoes and begin to work diligently to make it grow and harden. It seems unresponsive to our efforts, so we try using our hands instead. We manage to extract the cock’s head, and finally, it begins to react. We take turns giving him footjobs while the slave begins to take pleasure in the sensation, and then we start masturbating him together, each using one foot: we hold it between our feet like a sandwich. We are in perfect sync, moving up and down in unison, and then Gaia’s foot keeps it still while I rub my sole against it. The cock is a bit curved, and I notice Gaia looking worried about the direction of the impending explosion. She quickly repositions herself using her other foot. He is on the verge of climaxing and starts moaning like a sissy. Gaia and I increase our tempo, and the cock explodes in an uncontrolled burst, completely emptying those swollen balls, with some of the ejaculate even reaching us.
