A helpless slave, bound by unseen forces, is commanded to pleasure himself by the tantalizing sight of his mistress' cleavage. Her voice, a lash of leather, orders him to stroke his cock faster, harder, as she teases him with glimpses of her curves. The handjob is a dance of dominance and submission, a view from the sub's pov, where every touch, every command, brings him closer to the edge of ecstasy and humiliation.
