Prologue Part 1: 

From the journal of Lord General Cromwell

Despite the assistance of the Sons of Orar, it would be an understatement to say that the assault on the Craftworld was a failure. The Space Marines withdrew right as it seemed that the xenos were close to defeat, in a manner most unbecoming of the Emperor's Finest. Alavaan insists that the Craftworld Eldar had nothing to do with the raids on Imperial shipping and that there would be no honor in wasting the lives of our men over a deception. While I am loathe to suffer the xenos to live knowing that they have slain so many of our own, I am not in a position to question the wisdom or the authority of a Chapter Master of the Adeptus Astartes. 

Normally I would not be so upset by the death toll that has accompanied this campaign, but in this case I must admit to having a personal interest in these losses. My dear nephew Silon was attached to a regimental command squad belonging to the Cadian 334th regiment, one of the first to land on the craftworld and also the first one to be wiped out if the reports are of any indication. I've tried to tell the boy before that being in command of a fighter wing wouldn't save him if things went bad on the ground, but he insisted on going down there anyway- said that he wanted to be in the thick of combat instead of sitting on an escort carrier giving orders. I suspect that he thought there was more glory in serving alongside the Guard, but I doubt that this was what he had in mind.

As Silon's body was not found as we were retreating from the xenos' worldship, I can only assume that he has been taken captive by the Eldar. Segmentum Command has rejected my request to lead a rescue mission back to the Craftworld, and to try and negotiate for his release would be dangerously close to heresy. For now I can do little more than pray to the Emperor that he will survive whatever vile tortures the aliens have in store for him.

Prologue Part 2: 

From the logs of Autarch Kayleth

I have done many outlandish things in our Craftworld's defense. Will this truly be so different?

We were fortunate that the warhost had merely wounded the human with the Imperial Navy markings on its uniform- although in normal circumstances we wouldn't bother with taking prisoners, the Imperial invasion was just barely repelled and the Craftworld itself was badly damaged. In our current condition, we cannot afford to pass up any further advantage we can find, no matter how distasteful the methods for acquiring them might be.

The human was unarmed when we found him and no Imperial forces have been sighted since their retreat, so I have decided that it would be ideal to keep him confined in a containment cell. I believe that he may have information on how the human battlefleet managed to break through our defenses so easily, and any knowledge of our enemies' strategies will help us to prepare for any future assaults.

So far, our captive has proven himself to be quite reticent and seems convinced that we have brought him here to torture him for our own amusement, even when we have done nothing more rigorous than probe his mind. However, I have an idea on how to render him more compliant. Lately, the human grows unusually nervous when I am the one questioning him, and in the last psychic probe Veldoran noted that he is starting to grow...infatuated with me, to put it politely. While I am sure many of my kin would find what I am planning to do to be unnecessarily demeaning, its benefits will outweigh any perceived debasement on my part. Furthermore, a significant amount of time has passed since I last found release. As well as furthering our cause, this will likely provide a safe outlet for certain impulses which may lead me from the Path.

"Wake up, human. The Autarch is ready to begin the questioning."
 
Lieutenant Silon Cromwell awoke with a start, not sure whether to feel more unnerved about the fact that his wake-up calls were being transmitted into his head or that he was beginning to grow used to them. He had long since lost track of how long he had been a prisoner of the Eldar- his chrono had broken during the fighting, and the Craftworld seemed to have no real equivalent to "day" or "night" that he could recognize. For all he knew, he could have been held captive for less than a week or for well over a year. In any case, it was long enough for him to start wondering if the Imperium had presumed that he had just died with the rest of the 334th. And to think that he was so certain of the fame and glory he would achieve as part of the first assault; perhaps his uncle was right after all when he said to stay back on the escort craft.

With a groan, Silon pulled himself out of his bed and proceeded to make his way to the main chamber of what he assumed was the prison facility that had become his "home". While he still considered himself a loyal servant of the Emperor at heart, part of him knew that even if he did somehow manage to escape captivity and return to the Imperium, he would always be suspected of complicity with the xenos- after all, who would ever believe that he was not only taken alive, but kept in conditions no worse than any Imperial prison? In fact, the facility seemed to be getting rather warm lately, even with the thin, silk-like clothing that had been given him to wear in place of his worn-out uniform- something he found rather odd for a species that was supposedly infamous for the variety of tortures practiced on its captives. Still, he had just enough loyalty left to the Imperium not to reveal anything to the Eldar that might compromise Imperial security, much to their irritation. Steeling himself for yet another period of intense questioning, he entered the room to be confronted with a most unusual sight.

The Autarch who had taken it upon herself to lead his questioning was smiling; in all the time he had spent in this chamber with Kayleth in the past, he had never seen her show any sort of expression beyond a scowl as she incessantly quizzed him on nearly everything relating to the Imperial Guard and Imperial Navy, from the 334th's preferred tactics to the formations most frequently used by his old attack wing. At the same time, he couldn't help but notice that instead of the odd armor with the hawk-wings on its back she normally wore, she had chosen to wear a rather form-fitting set of robes that appeared to be made specifically to show off her thighs and chest- the latter of which was rather hard to miss, given how she seemed to be sitting in a way that almost looked like she was thrusting it at him. And most unusually of all was the presence of what appeared to be some kind of bed.

"You took long enough getting here, human. I trust that you are ready to answer whatever is asked of you?"

"Of course, Autarch," Silon replied, and before he could catch himself he added, "but...why the change of clothing?"

"Are you unable to notice the warm spell we have been having? Besides, if you did try to hurt me you would be dead in an instant. Now Silon, are you going to waste our time further or shall we begin the interrogation?"

If Silon didn't know better, he would swear that she actually sounded somewhat flustered. Pushing his confusion out of his mind, he gathered his composure once more. "So what are you looking to learn from this time, Autarch? How we broke through your orbital defenses? Or maybe something about how we managed to keep your warriors at bay as long as we did?"

As Kayleth prepared to respond, Silon noticed with some apprehension that her smile only seemed to grow in spite of his remarks so far and couldn't help but wonder what vile things she had planned in mind for him. Although he had heard enough of the horror stories about what the Eldar did to their prisoners to expect that she was planning some kind of unspeakable torture, nothing could have ever prepared him for what he was about to hear.

"Do you consider me to be appealing?"

"Err...what do you mean, Autarch? I don't think I understand." 

"Perhaps I should rephrase that in a way even a human can understand. Do you find my body to be sexually attractive?"

Kayleth could just barely suppress a smirk as the naval officer was unable to produce a response beyond letting his jaw drop. He would never be able to admit it to anyone outside of the Craftworld without being executed for heresy, but he had developed a crush on his interrogator as time went by- between her lithe yet curvaceous body, flowing jet-black hair, and the yellow eyes that could stare a hole right through rockrete, she was far more alluring than any xeno had any right to be. After what felt like an eternity of awkward stammering, he finally managed to form a relatively coherent reply.

"H...how did you-"

"How did I figure out you were infatuated with me? Your kind has never been good at hiding its emotions, and even the most slow-witted of the Eldar would be able to recognize your ogling for what it is. The psychic probes that were performed on you also revealed some very...interesting fantasies involving me." 

In spite of his limited experience with women, Silon knew just enough to be aware of the fact that having a woman find out that you had sexual fantasies starring her was a very bad thing, and even more so when the woman in question was a xeno witch who was probably looking for an excuse to kill him since the day they found him. Faced with the imminent possibility of a painful death, he found himself doing the only thing he could in his position- grovel for his life.

"Please don't kill me Autarch please please let me-"

As much as Kayleth enjoyed the feeling of being in control over another person's life, she felt compelled to cut off his feeble attempts at submission. 

"Kill you? Why would I waste a perfectly good source of intelligence doing that? I am not so heartless as the Dark Kin you humans keep confusing us with; in fact, I think it would be far better for both of us if I indulge a few of those fantasies of yours-like this." 

Before he could even ask what she meant, Silon found his hand being grabbed and moved to Kayleth's cheek as the Eldar took his cheek in her own with lips pursed open ever so slightly...

Then she kissed him. In the first couple of seconds, he had considered struggling, but the sensation of the Autarch's lips against his own quickly drove any thoughts of resistance out of his mind. Kayleth tasted surprisingly sweet to him, and in spite of her considerable experience in combat he found that her skin was smooth and rather pleasant to the touch. By comparison, his own taste was rather sour, but not unpleasantly so- if she tasted like a sweet wine, he was more like a strong amasec. 

Throughout the kiss, Kayleth had been subtly guiding Silon's hands, encouraging him to explore her body just as she was exploring his. While on an intellectual level she knew that this was meant to be little more than a means to an end, part of her was all too eager to indulge herself-as an Autarch, she had little time to give her needs an outlet, and it was only appropriate that the mon'keigh she had been assigned to question be given a very intimate look at Eldar supremacy, in more ways than one.

As Kayleth broke off their kiss, she approached the bed and slowly began to remove her robe, taking her time in removing each piece of the fabric to expose herself to the human- while she was no seductress, all it took to hold his attention was a few seconds in between each garment to hold his attention. First to go was the outer covering of the robe, thrown off to the side of the room as she took the time to stretch out her shapely yet well-built legs. This was in turn followed by an underlayer, leaving only what appeared to be a blue and yellow bikini with soulstones set into it visible. Silon was still trying to make sense of what had just happened, and with each piece of her garment removed his jaw slackened a little further, although the growing bulge in his pants and his inability to take his eyes off her made it clear he was enjoying the show. Seeing his eyes grow particularly wide as she removed the straps off her top to expose her pert breasts, she paused to address him. 

"Would I be correct in assuming that what has occurred has lived up to your fantasies thus far?"

"Is this some kind of trick to make me let my guard down?"

"I thought I told you that we are not going to kill you. Now answer my question."

"Yes, it's been enjoyable, Autarch. I just- well, I never thought this would happen. The Imperium doesn't stand for consorting with xenos and-"

"Must you be so formal now of all times? I give you permission to refer to me by name, so use it. And I suppose I should do the same as well. In any event, your Imperium probably believes that you are dead, and even if they did know of this we will not let them near the Craftworld a second time."

"Of course...Kayleth. My apologies."

"Well, are you just going to stand there? It's like you've never seen a female naked before."

"er, I haven't. The schola was segregated by sex, and-"

At this point he was interrupted by a burst of laughter from Kayleth that lasted a full minute. As undignified as it made her seem in front of him (more so than simply being half-naked in his presence), she couldn't help but be astonished as to how quick the human was to reveal the embarrassing details of his life after a simple kiss on her part. 

"I suppose that's one more thing you should be thankful to us for, then. Judging by how you're staring at my chest, I can tell you are rather interested in my breasts. Go on and do what you wish with them- I am not a delicate figurine that will break at the slightest touch."

Silon needed no further prompting, and quickly mustered the courage to take them in his hands. While they weren't quite as large as those of the Sisters who he had occasionally seen back in the Schola, he was no less intoxicated by the feeling of the soft yet firm mounds of flesh in front of him. Simple fondling slowly but surely gave way to kneading, and then to light squeezes- as he did so, he noticed that he could feel the Autarch's heartbeat quickening under his hands, and realized that to some degree that she was aroused by this too. For a moment he considered asking her how much of this was really interrogation, but decided against it for fear that she might withdraw her sudden favor towards him.

As Kayleth's breathing grew more rapid, Silon's attentions grew ever more daring and he began to start playing with her stiffened nipples as well. The small, pink protrusions were almost hypnotic in their appeal, and before long he had knelt down and put one of them in his mouth. Strangely enough, it tasted almost sweet to him, which naturally led him to start sucking at it (much to Kayleth's semi-concealed delight).

"I had always thought you humans were childish at the best of times, but I must say that this is new, even for me. Do you expect me to start giving milk as if I were your mother nursing you?"

Silon moved to let go of her long enough to reply, but Kayleth silenced any objection he might have had by forcing her nipple back into his mouth.

"I did not say that your attentions were unwelcome, Silon. Indulge yourself as long as you wish, but be quick about it. There are other activities in which I plan to engage with you and I do not want you to waste your energy now."

While he felt he could have spent hours doing so, he did not spend much more time suckling her, if only because of his curiosity as to what she meant by "other activities". She couldn't possibly be planning to have sex with him- or at least, that were his thoughts right until she casually removed her panties, exposing her hairless womanhood; had he been looking closer, he might have been able to see that she had grown quite wet because of him. If she was embarrassed by this at all, her expression did nothing to show it. The same could not be said about Silon.

"What are you waiting for? I stand naked before you right now, so the least you could do is strip as well."

"Of course, Kayleth. Right away."

As he momentarily fumbled with his clothing trying to remove it, Kayleth again found herself suppressing a smirk at her subject's nervousness and eventually decided to help him along; poking fun at his general lack of grace could wait for a more convenient occasion, and his earlier administrations had managed to turn her on quite strongly. The momentary blush that appeared on her face as she saw his newly exposed member made this all the more apparent to Silon. While he was far more uncouth than any Eldar male Kayleth had slept with, he certainly managed to compensate in size; Kayleth wryly noted to herself that his lack of experience would be fixed momentarily if she had any say in the matter. 

"Kayleth, are you sure that I can do this? Won't the Guardians be displeased if they find out about this?"

"I outrank them, and could simply order them to stand down if they pose a threat to you- have I not made it clear that you are too valuable of an asset to kill by now? In any event, they have no way of knowing what is going to happen here in just a moment."

"Sorry, it's just that- well, Eldar can't get pregnant from humans, right?"

"While the existence of such hybrids are not unheard of, it is a chance that I am willing to take. Now, let us go to bed- I suspect that you want this as much as I do, if not more."

On that note, she took him by the hand and led him to the bed. Sensing what was about to happen but no less nervous for it, Silon climbed onto it, with Kayleth following suit. 

"I can tell that you're going to need my assistance, so I shall take the lead for the time being. Lie down."

He needed no further urging to do so, and his erection made it clear that he was more than ready for for what would almost certainly get him executed for heresy on the (virtually nonexistent) chance the Imperium ever found him. However, as Kayleth finished straddling him and took a hold of his chest , she paused to tease his tip against the opening of her folds, once again grinning at his obvious discomfort.

"Before we begin, I have one last question to ask you. What does it feel like to lose your virginity to a 'xenos'?"

As she finished her sentence, she lowered herself all the way down, allowing herself only a short sigh of pleasure as he penetrated her. While Silon attempted to answer his question, all that came out of his mouth was an indistinct moan. He was no stranger to "entertaining" himself at his bunk during the long periods in transit between conflicts, but the new sensations buffeting his mind were like nothing he had ever experienced before. Her pussy was almost like a living ring around his cock- tight, warm, and pleasurable beyond imagination. For a while, he was content to simply remain as he was inside of Kayleth, and she was equally happy to indulge him.

"You feel incredible, Kayleth. I can't put it any other way."
"I thank you for your approval, but there is still more for you to learn. Here, try to match my movements." 

She lifted herself off of Silon just long enough for him to see her fluids coating his penis, and then promptly dropped back down again. Although he was tempted to simply let himself go right away, he was able to muster what self-control he had and eventually managed to match each of her thrusts with his own, filling the room with a resounding smack each time their bodies collided. After several such thrusts, she leaned in towards him to present her chest to him once more, and sure enough he started fondling her once again. If her heartbeat had seemed fast before, it was racing at this point, and even he knew that Kayleth's increasingly loud moans could mean only one thing- which is why he was surprised when she suddenly stopped. 

"Wait one moment...I need to lie down, then we can finish."

Acting on instinct, Silon spread her legs open and managed to re-enter Kayleth as she grabbed onto his arms. She seemed even tighter now than she did earlier, and her breathing was growing increasingly ragged. As she pulled him in for another kiss, he could swear her pussy was contracting around his cock. Before long, he felt her legs wrap around him with an unexpected amount of force as Kayleth blurted out something that not a few hours ago would have led him to think he was having a bizarre dream.

"By Isha, it has to be inside- just cum!"

Even if he did want to pull out, her hold on him was too strong to break, and as they kissed once more she all but screamed into his mouth as she reached her climax. Overwhelmed by her contractions, he came mere moments later, filling the Autarch with his seed and giving her a second, milder orgasm. Bereft of stamina, he simply collapsed, not even bothering to remove himself from her. As he started to drift off to sleep, he managed to catch one last quip from his interrogator turned lover:

"Humans aren't useless after all, I see. That was better than I had ever expected."

The next morning (or what passed for morning on a Craftworld, at least), he woke up to find himself back in his cell. As he groggily wondered whether or not the events of the previous day were real or not, he noticed Kayleth entering the chamber, in full armor and looking as curt as she normally did. However, he had a vague sense that something seemed different about her- she seemed less guarded around him and was looking at him with what could only be called fondness. 

"Autarch? What are you doing here?"
"Did I not tell you earlier that you can call me Kayleth? In any event, as a reward for your "good behavior" I have arranged for you to be transferred to a new cell, right next to my chambers. You have fifteen minutes to gather your belongings."
"Of course, Au-no, Kayleth."

For a second, Kayleth idly wondered if she was starting to fall for her captive herself, but pushed it out of her mind for the time. It would be undignified to lose her composure where it might be noticeable by her kin.

"And be sure to clean yourself. I expect you to be ready for another "interrogation" shortly."
