Keep going until she breaks

Had she been a bit more grateful, you might have called it a day here, but she just had to bite the hand that feeds. She manages to work a few more inches out of her throat before you act, closing both your hands on her head, metal gloves digging painfully into her scalp. "You do not get to make demands." You hiss and slam yourself back down to the base so fast and so violently that her entire body goes limp in an instant, eyes fluttering. "You're mine now. You made that choice. Now live with it."

You've been kind enough to give her more time than most to adjust in the beginning, but since she's clearly got quite a lot of fight in her, you won't have to hold back anymore. With an animalistic grunt, you stand up from your throne and begin slamfucking her tight resilient throat like a toy. The wet slaps of your hips hitting her mouth are echoing across the entire throne room. Spit and cum foam around your base in bubbles, getting pushed back up by the speed and **** with which you ravage her.

A few times she reaches up, tries to fight you off, but it's no use. Her body already betrayed her, cumming again long before you do. "It feels good to be used, doesn't it? Such a needy slut you are."

You ravage her throat until she's just a drooling mindless mess, dangling from your dick, gurgling and mewling as you pump another thick load right into her, again and again. You find a good rhythm and a perfect angle to just milk your cock one spurt after the after. What thoughts there were in that head previously, they are gone now. Your seed is so overloaded with your arcane might, every orgasm you pump into her is practically frying her brain a little more, and with how you're dumping enough loads into her, to already make her stomach bulge with the sheer mass of it, she's not gonna think clearly for a long time.

When you finally pull out, blasting the last powerful white ropes across her face, her eyes are dim and empty and her mouth is wide open, tongue eagerly lapping at empty air to claim a bit more of that perfect salty treat. The moment you let go of her, she collapses, leaning against the side of your throne, cum leaking from her mouth and nose and a few weak moans escaping her as the orgasmic aftershocks of your little 'deal' still run through her body. She will need some time before she's good for anything again, which leaves you to make a decision: Handle another audience or set your sights on different tasks?
