The door to the cell creaked open. Obi-Wan shook himself awake in time to see Darth Vader swagger in and hear him tell the troopers behind him to shut them in.

He eyed the Sith Lord warily, and moved away when his former student sat down beside him on the hard ledge that was the closest thing to furniture in the room. "What do you want?"

Vader smiled at him, edging closer until the only way Obi-Wan could get away would be to stand up. "Can I not just come to visit my favourite Jedi?"

Favourite? That didn't even merit an answer, so Obi-Wan refused to give him one, instead staring straight ahead at the bare metal wall opposite. He heard Vader sigh, then stiffened as a nose – a cold nose, he couldn't help noting – made contact with his neck, sniffing and nuzzling where the artery passed below his skin.

He did stand up then; subtlety could go kriff itself. He was not going to let Vader do that to him.

The Sith Lord followed him, backing him into a corner. There was not exactly anywhere in the cell for Obi-Wan to run and soon, after a bit of a struggle, Vader had the Jedi pinned against the wall with his body, his metal hand pinning Obi-Wan's wrists above his head. Obi-Wan tried to hit him with his knee, twisting away, but Vader pressed in, hoisting him up, until he was of the ground and the only thing holding him up was the pressure of the Sith Lord's body, legs pinning legs, hips on hips, chest on chest, with his arms held above his head and Vader once more nuzzling at his neck.

"Let go of me!" Obi-Wan attempted once more to twist out of Vader's grasp, resulting in Vader adding the Force to his hold, immobilising the Jedi, and binding his jaw shut. The Sith pulled away, smirking.

"Tut-tut Obi-Wan, where are your manners?" He paused momentarily, as if expecting an answer, and then continued, raising his flesh hand to caress Obi-Wan's jawline. The Jedi tried to flinch away, and found he was not allowed even that much movement. "Well, I suppose it doesn't matter. I was going to ask nicely, you know. You do remember the incident on the planet of, Llewebum don't you?" His fingers came to rest on Obi-Wan's pulse. It was beating faster than normal.

Obi-Wan did remember. It had been one of the first missions they had taken after the war erupted, and they had become cut off from any help during a cave in of the underground base they had been searching. Anakin had actually fared better than Obi-Wan to start with, as Obi-Wan had only water while Anakin had had enough blood for a feed on him, and that feed would last him a week. Digging their way out hat become priority, though the deadline was pushed back when they discovered some more water and abandoned ration packs.

It had taken them more than a week to dig their way out though. No one had known where they were, as they were technically not allowed in that area and had not wanted to leave evidence that could be used against them for the benefit of the Separatists they suspected they would find, and so no one had known where to look for them. And when the week was up, Anakin's hunger kicked in.

Ever since being Turned into a Vampire, Anakin had been accustomed to regular feedings – every three of four days – that could, in an emergency, last for a Standard week of five Standard days or possibly even six, though they had never tested it, and it would have the same effects on Anakin as depriving a Human of water after four and three quarter days. He knew that, because they had checked that, by waiting until Anakin's hunger began to kick in before giving him his next meal a couple of times.

And in the collapsed base, that time passed by, and they had a problem. Feeding from packets of blood was one thing, but they both had researched extensively about vampires after Anakin had transformed, and both were well aware that Feeding from a living being was not just only accomplishable when the living being was the same species as the Vampire had been before they Transformed, but that it would cause the being to recognise the Vampire should they ever be fed upon more than once. Multiple feedings upon the same person could also cause gradual transformation, instead of the "drain 'em" method as it was generally referred to, where the Vampire completely drained a person of blood, and then fed them some of their own.

Obi-Wan had known that they would not get out in time for Anakin to get the blood he needed, and so had offered his own. Anakin, who hadn't even considered the possibility of Feeding on Obi-Wan, had been stunned, and very grateful.

It had been an odd experience. Some texts had described it as arousing, and Obi-Wan supposed that it could be, under some circumstances, but it had been a matter of necessity, between mentor and student, and so for them, it hadn't been. Obi-Wan hadn't regretted saving Anakin's life. He had not, however, been prepared for the feelings that came with the first prick of the fangs.

Vampire fangs were teeth, and rather large ones at that, and as such would rather hurt it they were stuck in someone's neck. This was not conductive to people letting Vampire's feed on them, so as a semi-necessity, they had evolved painkilling venom that that the first prick of the fangs injected into the victim.

Obi-Wan had known this, and been prepared for it. Anakin had known this, and had waited a moment for it to take effect despite his hunger. What they hadn't expected was the odd mutation of the venom Anakin's Force sensitivity had caused. Force sensitive Vampires were an unlikely occurrence, after all. Sensitive's were trained, and that training gave them a purpose, which would prevent them giving everything up and joining the ranks, and which also allowed them warning regarding injuries that were mortal unless turned, vampires that were recruiting without the victims permission, and the like.

The mutation to the painkilling venom had caused Obi-Wan to have a reaction somewhat akin to a drug high, along with automatic submission to the Vampire. He had been utterly helpless, and it had shaken him. It had shaken Anakin as well when he had told him.

Yes, he remembered. And now, with Vader trapping him against the wall, the chill seeping through thin prison clothing from the metal behind and with Vader fingering his pulse, he knew Vader would have none of the moral compunctions Anakin had had about taking advantage of that.

He had expected torture, when he was captured. He would have preferred that now. Torture, he knew how to resist.

This, he knew he couldn't. And it scared him.

Vader's smirk grew, yellow streaks creeping into his eyes with whatever he was thinking, before he suddenly pounced on the Jedi, crushing him against the wall, metal hand resuming its grip. The Force restraint melted away even as he felt the tell-tale prick on his neck.

No…

Vader laughed mockingly, breath raising goosebumps on Obi-Wan's neck – and then it didn't as the venom took effect, numbing the area before moving on to blur Obi-Wan's sense of reality for a moment, the odd and momentary sensation of the places in his brain that produced the endorphin that in humans induces feelings of pleasure going into overdrive even as he felt his muscles relaxing, shutting down, submitting to the being that had the power to cause that sensation.

He'd been too surprised on Llewebum to really analyse what caused it. This time though, he felt the moment when it happened, and wondered, in a distant corner of his mind, whether it was an unconscious Force use that took advantage of the endorphins flooding his system. But it didn't really matter, at least right now. Whatever caused it, the effect was the same.

Vader let go of his wrists, seemingly testing the effects. He needn't have worried, Obi-Wan thought bitterly as the released limbs fell and came to rest limply at his sides.

The Sith chuckled, and licked the small puncture marks, grinding his hips against Obi-Wan for a moment before he stepped back, satisfied that he had compounded the Jedi's feelings of helplessness and disgust. Obi-Wan fell to the floor, staggering as his feet impacted and then as Vader steered him over to the bench with nothing more forceful than a hand between his shoulder blades.

The hand fell away, and Vader regarded him for a moment, taking in the lack of tension in his stance, how his shoulders bowed forward just slightly in comparison to his usual almost military stance, the way his head was lowered and his gaze fixed on the floor.

More yellow crept into the Sith Lord's eyes. "Well, well, well. General Kenobi, a Jedi Council member and Rebel, utterly at my mercy. Look up."

Obi-Wan's eyes rose. He would dearly have liked to take it literally and gaze at the ceiling, but that proved impossible, and he found his eyes meeting the yellow of Darth Vader's. There was a dark, anticipatory smile on his face.

"You don't like that, do you?"

No. No, he didn't like it at all.

"You know, I wasn't entirely sure it would hold, what with you not having my teeth in you to inject more," Vader mused. "I must remember to experiment just how much I can make people do with this as some point – I do hope you won't mind being the test subject?"

He minded very much. But his mouth didn't move, and the words lay heavy in his throat as he attempted to make them known.

"I take it that you don't." Vader's smile was more a predatory bearing of his teeth, fangs included. He sat, and then manhandled the other into his lap. "Head back."

Even as he felt his body comply, he hated himself for it.

And he hated Vader for putting him in this position.

The Sith Lord bent his head, holding the Jedi close in grotesque parody of caring as he broke the skin – on the side of his neck that hadn't been anaesthetised.

A.N. As stated in the summary, not to be taken too seriously. Reviews would be nice, even if just to tell me if the rating was justified or over-the-top.
