Not quite

When you come to, it's dizzy and disorienting. You're no longer in the small green cavern, and instead have somehow been transported to a room with padded, white walls. There's a cold metal feeling pressing against your bare back, but when you try to move you're alarmed to find that you're completely unable. You can see your arms, and they're not restrained, but they simply refuse to respond to your brain's requests for them to move.

"Ah, finally awake, I see," comes the voice of Gil'nalak in your head. "I called in a few favors to get you here, and a few more to prepare for when you eventually wake up. You see, I'm ready to seize my inheritance and control these caverns, and I'm going to use your body to do it."

You try to form words, but your mouth refuses to obey. "That sense of helplessness? That's going to be normal from now on dear, so just hang on and enjoy the ride. We've already gone about isolating your consciousness, and the final step is ensuring that mine can take control." Even now you can feel the demon's mind pushing against yours, an invisible weight in the confines of your consciousness.

The sound of hooves echo through the room, as an unknown being enters through a door out of sight. A female voice greets you, seemingly talking into thin air. "Ah, good, she's awake. We can begin the final steps, if you're ready Gil."

The pressure on your mind increases, and you feel yourself say a single word, "Yes," completely unbidden. "Excellent," replies the female voice, and you feel the slight pinch of a needle on the back of your neck. A strange liquid courses through your bloodstream, and you can almost feel it as it moves down your body, eventually settling in your nether regions.

A tingling that you recognize from the demon's initial possession fills your groin, and you strain your eyes to look down. Your cock is already fully erect, but you feel no arousal, and even as you watch the flesh begins to expand outwards and upwards, lengthening and thickening. After several seconds, the end shapes itself into a distinct shape, and you realize that it's head has formed the flared shape of a horsecock.

The tingling hasn't finished, and though you can no longer quite see the changes, you feel that it's centered itself on your pussy, which you can feel getting wetter by the second. Unknown to you, it follows the pattern of your other sex organ, deepening and widening, until it also resembles its equine counterpart.

The demon seems emboldened by these changes, and you can feel your hands and feet starting to move ever so slightly, through no will of your own. Again, the warmth spreads through your body, and you orgasm without arousal, semen shooting out of the end of your new horsecock, splattering across the ceiling and far wall. You start to feel your grasp on consciousness again fading, but this time is different, it feels almost as if you're slipping away entirely. The demon can't help but get in the last laugh, and his voice is the last thing you ever hear.

"Thank you for your body, adventurer. I will put it to good use."
