Your rescue reveals more than you expected

"Don't worry miss, you can count on me" You declare with a deceitful confidence. In your world, cave trolls are excessively dimwitted, and you count on them being so here, in a world where everyone seems at least a little dumber than they normally would be. You slowly make your way up the mountainside, seeing the troll as he goes along, carving a new path of his own through the sheer rocks. His attention is easy to avoid, even despite his propensity of being distracted by the slightest noise. You use this to your advantage, throwing rocks in a wayward direction every time you want to ensure he doesn't see you. He looks without fail, regardless of how feeble your throws are. Following him up the mountainside slowly, you find the entrance to what appears to be a large cave. There's no outward sign that this is the same cave the sticky elf was talking about before, and the troll goes about his business elsewhere, climbing higher up towards the top of the tit-shaped mountains. The only way you can find out for sure is to venture inside, so that you can "rescue" these sex crazed elves.

The light fades quickly as you go through the cave, going near pitch-black in just a few minutes. Thankfully, your elf eyes permit you to see even in this bleak darkness, and something seems a little odd. The walkways and chasms seem engineered rather than natural, and clearly not built for something the size of a troll. If there's something in here that's not an elf, and not a troll, you may have bitten off more than you can chew. Still, the raging erection is still in control, and you press on, pushing any reservations off to the side, viewing the sweet rewards as being worth any risk. Your real fear for the moment is falling, as there are many ledges you have to cross in this immense cave system; a slip here would lead you to falling for minutes before you met your final grizzly end.

Idle exploration doesn't get you much to go on for a while, and you start to think this is a massive dead end. Just as you start to turn around, you begin to hear the faint but unmistakable echoes of moans and screams. Knowing you're in the right place, you are drawn ever deeper and closer in, trying to follow the sound through the reverbating walls of this vast pit. With some luck and a few wrong turns, you do eventually find the chamber where the captive elves are kept. As you were told, they are kept individually apart from each other, bound to the walls by immense chains and collars, unable to touch themselves or each other in any means. Completely robbed of any ability to please themselves, they have all gone stark mad, trying to move against the stone walls to make anything happen. You see one grinding herself on a stone, even this driving her into pleasure, but never enough to orgasm. There are so many, and in such dire, open lust, that you scarcely hear yourself think. Your own rock of a cock twitches involuntarily, eager to help these elf women with their trauma, but a sudden sound changes everything.

You hear hidden doors open from the other side of the chasm. From it, you see two drow women, dark elves, march into the prison with purpose and authority. Or at least, you think they're women. They certainly look like women from the tits up, but from the waist down is a different story. Each has a cock, seemingly mammoth in size and stature, erect and weaponized. You watch them open a cell and unleash an elf. Dragging her out into the hallway, where the other elves can see her. What looks to be a struggle of defiance at first has another context. The elf isn't struggling to break free, it's trying to fuck them already.

"Listen and hold still you dumb slut!" One of the drow yells, beckoning it to stop. She tries her best to hold still, letting them position her on all fours. The one standing behind her holds her by a chain, a necessary restraint from her immediately trying to suck the other's cock.

"You really want this? We'll fuck you until what's left of your brain falls out, but there will be consequences."

"I don't care!" The young elf screams as she writhed between the two drow cocks "I need it! Please, you have to fuck me, Give me those wonderful cocks!"

They look at each other as they laugh "Don't worry, we'll give you exactly what you want. Welcome to the club..." Without wasting any time, they skewer the elf through her throat and ass with their cocks, causing the elf to convulse as the barest touch throws her into orgasm. The rest of the captive elves become even louder, begging to be the next ones to be fucked. The elf in the center tries her best to fuck both the cocks, but the drow take the iniative, pinning her down and using her as a mere cocksleeve. Finally getting the pleasure she wants, she clearly fogs over as she is mercilessly pounded. The sight is something truly wondrous to behold, and you take a hold of yourself as you watch, stroking your cock quickly, even as you are slightly horrified by both what you are seeing, and what you are doing.

The elf convulses near constantly as she has wave after wave of orgasm, having been denied for so long. The drow laugh as they fuck her "You are such a dumb, hopeless thing, elf. You have no idea what you're in for..." Beyond the occasional beratement and moaning, the place is silent. As you reach your climax, well before the drow, you hold your breath to cum silently, shooting your load on the ground. You aren't exactly proud of what you just did, but you couldn't resist the urge. Deep down, you know this place is getting the better of you, but you're starting to not really care

The drow finally approach their own orgasms, their moans growing louder, pounding even faster into her ass and throat. They reach a fever pitch as they both dump their seeds inside the needing holes of the elf, and emit a low laugh as they finish. Pints of their thick slimy seed pump out of her holes, even before either pulls out. As they do, they both step back and look at the elf they just defiled, finally content and satisfied with what just happened to her. One of the drow imparts a final dark laugh "It shouldn't take long now, not with all that cum. Haven't you ever heard to beware what you wish for?"

The post-fuck bliss the elf in quickly changes to horror. Her back arches upwards in pain, wriggling around as she starts to change. The soft blonde hair turns white, her gentle skin takes a dark purplish hue. Her hands move towards her legs as she starts to grow her own massive dick.

Drow cum, at least here, changes elves! As she changes and the new she-cock grows to a size comparable to the other drow, she begins to stroke it furiously. The others watch with perverse glee as she pumps her new piece of anatomy, releasing untold amounts of sexual tension. The new experience quickly overwhelms the former elf, cuming quickly with her own cock, covering her own chest and face with cum. The transformation seemingly done, and content with the display, the drow take her by the arms and drag her away "Let's introduce our new sister to the rest of the family..." You hear as the voices trail away. You hear a different voice pop up behind you.

"Who the fuck are you? What are you doing here!?" Spinning quickly around, you see another drow, armed with a real spear. Without waiting for an answer, she tries to pierce you with the weapon. You hold your arms up in vein effort, and find yourself transported quickly through the planes, back to Siobhan's office. The sun has practically set, leaving an orange hue in the room through the window.

"Well, looks like you had fun in there..." She said, seeing a drop or two of cum still lingering on your dick.

"No! Well, okay yes, but I watched something terrible. Drow were taking regular elves and transforming them into their own kind."

Siobhan seemed oddly unconcerned "That's a little odd, but not entirely surprising. The biology between the two is identical, for all intents and purposes. Most of the differences between their kind and yours is cultural."

"That's all? How can you look at this so academically!? We have to go back, and do something about it!"

"Do we now? And why is that?"

You're startled such a seemingly obvious question being asked "Because it's the right thing to do! Those women are being **** and changed!"

Siobhan holds up a glass orb from her desk "That's not the series of events that I saw. You certainly didn't step in to do anything when you may have had the chance. This is the natural order of things in their world. We have to respect that it is different from ours, and trying to install our code on them will only lead to disaster. I sent you there to prove the place exists, not to allow you to set up home or become their champion. Your actions will have unintended consequences, I promise you. Forget what you saw, and move on. We have work to do."

"I don't think that'll be something I can forget" You say quietly. Siobhan is unremorseful "Fine than, just don't let your memory's or your suddenly newfound morality interfere with the plans. I am not sending you back, and there's far more you need to learn before you can get there yourself."

"I understand" You say defeatedly. Siobhan smiles as she moves from her desk "Good lad. Now, go get cleaned up and have some food. We'll see each other in the morning, where we will have much more to learn..."
