Bound and powerless, the slave feels the cold water against his skin as his mistress, clad in a barely-there bikini, descends upon him. She straddles him, her body wet and slick, her breath hot on his face. "You will take what I give, when I give it," she hisses, her hand wrapping around his balls, squeezing just shy of pain. She grinds against him, her thong rubbing against his cock, teasing, tormenting. She leans back, her hands now free to inflict worse, her heels finding their mark, pressing, twisting, as he grits his teeth, trying not to cry out.
