Fox Mulder had never been the sort of man who had to see something to believe it. There were things that he simply took for granted -- such as the existence of aliens. He'd always known that they existed. That belief had been one of the constants of his life.

He'd never demanded actual proof before his eyes that the aliens were there. He'd been sure that they were; seeing them wouldn't make them any more real for him, it would only confirm those beliefs that were already deeply entrenched.

He never would have thought that he would actually be traveling around in time in space with an alien. An alien who was nothing like the image he'd had in his mind of an alien race; an alien who he actually regarded as a friend.

A friend? Mulder sighed as he glanced over at the Doctor, who was bending over the console studying something intently. He wanted the Doctor to be more than a friend, but that wasn't a subject he could easily bring up with the Time Lord.

He caught his breath at the sight that was presented to his eyes -- when he'd looked up, his gaze had been drawn to the Doctor's rear, as if it had known exactly where he wanted it to go. And now he couldn't tear his gaze away, even if he'd wanted to.

Why should he want to? Mulder asked himself as he let his eyes roam over the other man's body. That ass was too delectable for words, he told himself, his breath catching in his throat. Someone should put a Grade A Prime stamp on it.

That was an ass that made him want to reach and touch a particular someone.

Holding back another sigh, he leaned back against the cushions of the couch he was sitting on, his gaze still on the Doctor. It was weird that he should feel like this about a man. A man who wasn't even human, at that.

He might as well face it. He was attracted to an alien. That was something he'd never thought would happen in a million years. He had always thought he would chase after the aliens, subdue them, shoot them down, all of that childish fantasy stuff.

It had never occurred to him that aliens might be something like humans. That they might not he a hell of a lot different in some ways. He'd always thought that they would hide what they really looked like, that if they did resemble humans, it would be a disguise.

But the face that the Doctor wore was no disguise. He'd actually asked the Time Lord about that, not long after he'd made the decision to come aboard the Tardis. He'd wanted to know if Gallifreyans looked different from humans, if this was just some form they could take.

"No, really," he'd insisted during that conversation. "Is this just a mask you're wearing to make yourself able to blend in on Earth? Are you really a lizard underneath that skin, like that movie V? You can't look so much like a human."

The Doctor had placed Mulder's hand on his face, letting the other man feel that smooth skin. "No, I'm not a lizard underneath this skin," he'd said, his voice soft. "I'm just what I appear to be, Fox. Just a man. Though not a human man."

He'd stroked his fingertips over that soft skin, marveling that the Doctor could feel so human, as well as look human, and yet be an alien. But he was fast finding out that not all aliens were what he expected; the Doctor wasn't like his concept of an alien at all.

"Haven't Gallifreyans ever wanted to take over the Earth? Don't most alien races want to enslave other planets -- or destroy them?" he'd asked when they'd had their first discussion about alien races. That had changed some of ideas in a big way.

The Doctor had started to shake his head, then he'd sighed and nodded. "A lot of other races do, yes. But there are alien races that only want to live in harmony with the rest of the galaxy. It's a pity that after all these millennia of existence, so many of them haven't learned to do that."

"I just expected aliens to be .... well, more alien," Mulder had told him, his eyes still on the Doctor's face. "That they would have to hide themselves, to wear masks of some kind to try and fit in with us. I guess I'm just surprised that you don't look different."

The Doctor had promptly wrinkled his nose, crossed his eyes, and stuck his tongue out.

Mulder hadn't been able to hold back the explosive laughter that had bubbled up inside him. He hadn't expected aliens to have such a sense of humor, either -- but the Doctor could make him laugh at a moment's notice, more than anyone ever had.

After a few moments of holding the pose, the Doctor had let his features return to normal, laughing along with Mulder. "Did I look so terribly different then?" he asked, his voice soft. "It doesn't matter what I look like, you know. I'm still the same inside."

"It's too bad everybody in the universe doesn't think like that," Mulder had told him, shaking his head. Privately, he couldn't help thinking that it did matter how the Doctor looked -- he could blend in with humans, and no one would suspect a thing.

And the man was gorgeous, Mulder had said to himself, definitely a sighg worth seeing. His gaze lingered on the Doctor's face, focusing on that mouth. The mouth that he'd had the sudden urge to lean forward and kiss -- though he had managed not to act on that urge.

One thing he definitely hadn't expected when he'd met an alien and agreed to travel in time and space with them was to be sitting there while that alien pulled silly faces at him. But then, so much about this experience wasn't what he'd thought it would be.

He hadn't expected to be attracted to an alien. He hadn't expected this alien to look so human -- or to be more concerned about the safety of the human race than most humans were. He hadn't thought for even one second that he could fall for someone who wasn't human.

But he was.

There was no denying it. Mulder took a deep breath, sitting up on the couch and fixing his gaze on the Doctor again. The other man was still bending over the console, giving Mulder a wonderful view of his bottom. It was a sight that he could drink in all day.

Of all the sights he'd seen in his life -- and he'd seen some things that he'd thought nothing could ever compare with -- he had to put the Doctor's ass in at least the top three. It might even be at number one -- if the sight wasn't covered by the denim fabric of his jeans.

Who was he kidding? He wanted the Doctor. In a way that he'd never wanted anyone before, male or female. And he had absolutely no idea if that feeling was returned, or if the Doctor simply thought of him as a friend and companion.

He didn't want to be just a companion. He wanted more. He wanted to have a relationship with this man, to get to know him in the most intimate of ways. It didn't matter that he was an alien. He was the most vital, interesting, desirable person that Mulder had ever known.

Of all the people he could have desired -- it had to be someone who wasn't human. This was what Scully would have called a delicious irony, he thought, smiling wryly. She would love to know that he was falling not only for a man, but a man who was an alien being.

The Doctor didn't seem like an alien. He seemed more human than so many of the criminals that Mulder had dealt with during his years in the FBI. He was a good man; the fact that he wasn't human didn't seem all that important.

What did it matter if he hadn't been born here on Earth? He had a good heart -- or hearts, in his case. He was a better person than most humans Mulder had met. Others might only notice that he was beautiful on the outside -- but his inner beauty matched the outer.

The Doctor bent lower over the console; Mulder swallowed hard as the fabric tightened across the other man's backside. He couldn't tear his eyes away from that sight. All he wanted to do at the moment was go over to the Doctor and take him into his arms.

But he couldn't. Not yet. He had no idea if the Doctor might possibly view him in that way, and he wasn't going to make the mistake of jumping in head first without some kind of assurance that those sorts of advances wouldn't be turned away.

Still .... faint heart had never won fair maiden. Or handsome man, in this case.

Whatever that old saying was, it would do him no good to sit here and ogle the Doctor's ass, dreaming about what he wanted to do instead of daring to do it. What was the worst that could happen, anyway? It wasn't as though the Doctor would leave him out here somewhere --

A shudder went through Mulder at the thought. No, the Doctor wouldn't do that, but the Time Lord could very well have no problem with taking him back to Earth and leaving him there, closing the door on any further experiences in time and space for him.

He didn't want that. Not only did he want to know the Doctor better, but he wanted to stay here on the Tardis. He was fascinated by everything he'd seen, and he wasn't ready for it to end. If he was honest with himself, he didn't ever want it to end.

The more he looked at the sight of that perfect ass tempting him, the more he wanted to get up and walk over to the Doctor, to pour out what he was feeling and admit that the attraction was overwhelming. But he wasn't going to. Not yet. He was going to take his time.

But in the end, he'd get what he wanted. And if he didn't .... Mulder allowed himself an inward smile, standing up and heading for the console. If he didn't get what he wanted in the end, he could at least say that he'd had a good time trying.
