You power through it

You endure 4 hours of nonstop, hardcore fucking. All while being physically incapable of cumming. When Ali finally comes in to check on you, you're a mess. You're drenched in sweat, your makeup is ruined, you have tears streaming down your face, and arms and legs are wobbling out of control. Ali laughs at you and removes the machine fucking your mouth.

"How are you feeling?" He chuckles.

"I...am...fine...fuck...you," you struggle to reply.

Ali frowns, "So, you are as stubborn as I thought you were. I was hoping this would be enough to break you but clearly not. Let's try something else."

Ali releases you from the machines and brings you to the corner of the room. There he chains you up in a standing position with your back to him. He conjures a long whip.
