Bound at the wrists and ankles, the slave is utterly helpless, their body a playground for their Mistress's kinky desires. She stands over them, her naked form a symphony of dominance, her strapon cock a promise of pleasure and pain. She teases the slave, running the head of the cock along their slit, making them beg for more. Then, with a wicked grin, she pushes the cock deep inside, filling them completely. The slave's moans fill the room, their body writhing as their Mistress begins to fuck them in earnest, her hips moving with a fierce, unyielding rhythm.
