Only what's natural, though you haven't accepted it yet

As you watch the massive penis slowly approach your head, your trance is broken by Buldar.

"Ever made love before, young lady?" he asks.

"O-o-of course," you lie.

"You're a bad liar darling," he says, pointing at your penis, "Well then do you ever jerk off that little thing?"

The blush that quickly spreads across your face is all he needs. Your head reels, trying to understand why he's suddenly asking all these questions.

"Ah well, not platinum, but a gold's not bad for you, hey Cocephalos?" says the orc.

"I think there's a certain charm to it," rumbles the centaur from above you, "Now let's hope she's ready. Open wide."

You kneel in confusion, not understanding what is happening around you. The orc walks up behind you and sharply raps the back of your head.

"Open your mouth, elf."

Fearful, you obey. You open your mouth wide. The centaur advances, and his cock approaches your face, until it's brushing against your lips.

"I can't do this all by myself lass, you're going to need to work with me if you want to make it easy for you."

You still don't understand what's happening, until Buldar holds your head still from the side. The centaur thrusts forward, pushing the head of his cock into your open mouth. It doesn't quite fit, but after applying a little extra pressure, its head pops past your lips and is suddenly filling your mouth. You begin to panic as new smells and tastes wash over you and you bite down hard.

The centaur lets out a low yell and curses, "Fucking elven whore, we need to teach this bitch a real lesson."

The orc pulls you off the cock head, slapping you twice before lowering his heels on your exposed testicles. He doesn't push hard, but pain explodes through your groin. He holds the pressure there for a second before pulling away.

"Are you going to listen properly now slut?" he says.

"Y-yes, please," you say, "I'm sorry, I don't kn-know what to do."

"Suck his fucking cock, it's not hard. You can use your hands this time."

Realization starts to dawn on you as you straighten back up, reaching a hand out to hold the massive shaft. Running on fear, adrenaline and a strange almost instinct in the back of your mind, you begin to lick he cockhead, before spitting on it and spreading the saliva with your hand. As you take it back into your mouth, and begin to suck, it fully hits you. These creatures want to fuck you. You're sucking this centaurs dick. And, even more horrifying, you realize they probably won't stop there. Terrified of the consequences of failure, you suck with all your might. Another dribble of urine spurts from your penis, and you feel something wet slide out of your asshole. Even more humiliated, you think you've soiled yourself fully, but no scent of feces materializes. Cautiously, while still working the shaft with your hand and the head with your mouth, you reach back with your free hand to touch this goo. Bringing your hand back you see that it resembles mucus or saliva. It smells strange, but not entirely foul.

After working its cockhead back and forth in your mouth for several minutes, the centaur pulls it out.

"Fuck, even when this bitch is listening, she can't keep her teeth away. We'll need to do something about it."

"We can use the jelly now," says the orc, "until we can apply a more permanent solution."

"Aye," says Cocephalus, "Apply the jelly, then you try out her mouth properly, Dacchus. Let's prepare that other hole for me."

Another centaur, presumably Dacchus steps forward, while the orc fetches something, presumably this jelly. When he returns he grabs your face, forcing your mouth open. He thrusts several slimy fingers past your full lips, and rubs some sort of substance all over your teeth and gums, before stepping back.

"Give it a moment to let it work," he says.
