Serf is on his knees with wrists handcuffed behind his back and ankles bound with rope. Zayda is smugly facing him with her erect dildo and wearing pigtails, ready to inflict some *******. She first tortures his nipples with ****** clamps, then playfully kicks his tender nipples with her spiky boots. Serf screams and begs for her to stop but this only makes zayda kick harder and giggle more joyfully. She then instructs serf that he will repeatedly fuck himself in the ass, then mouth, as she responds to messages on her phone. Getting up and down and turning around is very strenuous for serf. We see him get stressed and tired very early. But zayda doesn't care. She makes sure that cock is jammed deep in her slave's ass every time, yelling at him and spanking him when he's not doing good enough. She also makes sure that he sucks cock like a good little sissy: deep, hard, and like he means it. Serf continues to fuck away, on both ends, as zayda ignores him and takes care of her business. Because he is such a worthless worm, she again has to step in and start guiding the cock in serf's ass, as he is so exhausted and ****** by now. She also ****** her cock down his throat until he gags, not allowing the sissy bitch to take his mouth off of her enormous cock. Zayda is displeased by how slow he is, so she starts yelling instructions, "mouth!", "ass!", "mouth!", "ass!", until serf is immobilized by pain and exhaustion. She decides he is not enthusiastic enough, so ****** him to beg for her cock, "please, goddess, fuck my disgusting man pussy and honor me with your *****." then she makes him fuck her cock some more as she paddles him until his ass cheeks are sore and red. Serf is ****** to make pig noises like the worthless piece of he is. When zayda is finally finished torturing serf with her strap-on, she leaves him bound on the dirty, concrete floor to think about what a disappointment he's been.
