A power-hungry mistress takes control, her strapon ready for a bisexual slave's total submission. She commands her pet to strip, revealing every hole ready for her merciless use. The domme grinds her harnessed cock against the slave's ass, then forces it into their mouth, gagging them on its length. With the slave bound and helpless, she teases their pussy and ass with the tip, drawing out moans of anticipation. Finally, she slams the strapon deep into their ass, fucking them hard as they squirm and beg for more.
