Today, Mistress Gaia and I have securely restrained our slave: his hands and feet are shackled to opposing walls of the room with arms and legs spread apart. Gaia and I, with our legs encased in nylons, approach him and begin with slaps to his face and swollen balls. The more we strike him, the harder his cock becomes, nearly obstructing our ballbusting sessions. We slap his face and kick his balls, without respite and continually increasing the pace. Our fantasy leads us to slap his balls as well, and we finish punishing him by kicking him from both sides: me in front, and Gaia from behind.
