Of course!

You can't help yourself! You need to taste his seed. It's a palpable requirement for your continuing existence. You pull his cock out of your throat, letting his head rest on your tongue, and jerk his shaft. Your hands pump furiously, eagerly awaiting the first taste of your reward.

The first jet of thick white goo splashes your tastebuds sends you into a minor shock. It was the best thing you've ever tasted! All your old favorites disintegrate in your memory as more long gouts of jizz spurt into your mouth. You swallow only when there's no more room to hold it, and open up for another load. Your hands continue to jerk him off, making sure he is milked to completion. Your excitement leaks down your thighs as you experience complete, shameless bliss. At some point, you have your own orgasm. But it is lost in the fog of joy at being a slurping, gulping cumslut.

The troll, eager for more stimulation, stuffs his massive cock down your throat. More cum spills down your throat. Your eyes roll back, enjoying being used as a cumdump. You even feel your stomach bloat with the seed of this filthy creature. A part of you knows this will be enough sustenance to keep you alive. You'll never have to eat or drink anything else! As the shaft pulls from your lips, you give it a series of sloppy, devoted kisses. You have found your true purpose.

The orcs find you...eventually. When the door opens again, they see what you have become. Your face is splattered with jizz and spittle, as are the torn remains of your dress. You look away from your Master for the first time in days, gazing at the intruding greenskins with fright. The troll is much bigger than them, but you fear that they might take you away from his wonderful cock. Instead, they close the door and leave you alone. You lose track of time, of where you are, even who you are. All you become is a sucking mouth; you are just an oral toy for your new master. He gets tired of you eventually, but that won't be for a while. For now, enjoy another dose of creamy reward. You win!
