A squad

Martha stumbled along, shivering slightly. She crossed her arms over her chest; it was as much for modesty as it was for warmth, the chill english air one of the clearest indications of where they were. So long as she kept a couple of steps behind the Doctor, and so long as they were alone...

The Doctor kept striding along. He occasionally looked from side to side, taking in the location.

His casual air of confidence was a stark contrast to Martha herself, biting her lip, glancing around more to be sure they were alone than to take in the view.

And then, quite suddenly, there was the distant rumble of cars. Martha squeaked; the Doctor glanced towards the noise, more curious than worried. A few tall hedges marked the side of the road; it was a good few seconds before the vehicles had moved past that and come into view.

"Halt!" a voice cried.

It was a convoy. A green open-topped jeep led the way, soldiers standing up to fit on the seats, while behind it a handful more jeeps trundled along. An army truck followed them, emblazoned with a logo identifying them as 'UNIT.' As soon as they saw the two travellers they came to a stop.

With a shout, half a dozen armed men leapt from the foremost jeep, hurrying closer.

Martha squealed, darting behind the Doctor for cover. Her cheeks burned.

"Identify yourselves!" one soldier barked. "You there, where we can see you!"

Nervously Martha stuck her head out, past the Doctor's upper arm. She still kept her arms crossed, even when she was using the Doctor's back for cover.

"Don't shoot!" she squeaked.

"Hey there, no need for that," the Doctor said. "We're just having a walk."

"You're within the perimeter," the soldier said. "Who are you?"

"Perimeter?" the Doctor said. "Now why's there a perimeter?"

"Answer me!"

"I'm the Doctor," he said, and stepped sideways. "This is Martha. Now you, what's this about a perimeter?"

Martha squeaked for just the second she was in view, hastily dropping a hand, too late, to hide her pussy. She sidestepped back behind the Doctor, whimpering at all the second glances she suddenly got from the UNIT men.

It didn't help that there was a brief pause after that; she couldn't tell if it was at the Doctor's name, or the soldiers realising that this time he was accompanied by a nude woman.

"Doctor?" the lead soldier said eventually. "The Doctor?"

"That's me," the Doctor said. he paused, dropping his voice to a more conspiratorial murmur. "Don't tell me I'm following behind you in that truck. This could be dreadfully embarrassing."

"The last I heard you were investigating Farrel Autoplastics back in the city," he said. He hesitated. "I know you can change how you look, but are you really..."

"One and only," the Doctor grinned suddenly. "Well, one of two. Well, of ten. Well- Don't mention this to him, ok? Time travel and all that. Need any help with whatever's going on?"

"I-" the soldier paused, then quickly straightened. "Come here. I need to be sure you're the Doctor."

The Doctor nodded. He took a few steps forward, apparently not bothered by the couple of guns trained on him. Hurriedly Martha took a step forwards, hoping to still use him for cover-

"Not you!" the soldier barked. "If you're not who you say you are..."

Martha yelped, stumbling back and faltering on the spot. Yeah, sure, like that was their only motive for keeping her standing in the open. She squirmed still, feet never staying still on the road.

One arm was crossed over her tits, hand resting on her opposite forearm for warmth, but meaning each time her other arm shifted, her cover moved too, dark nipples sudenly peering into view occasionally. Her other hand went down, between her legs, hips pressed-together as it was.

She didn't know how she'd ever gotten used to being nude like this, but she must have somehow...

She whimpered, cheeks burning as she waited desperately, feeling the gaze of the whole squad on her.

The test was simple, the soldier checking the beat of the Doctor's two hearts; it wasn't like there were many more people wandering around with a second heart in their chest.

It just felt like it took forever. Martha fidgeted, shivering again, and breathing in relief when the Doctor moved back. Guns lowered, and she quickly darted behind him again, breathless.

It wasn't much cover, but it was so much better than being out in the open.

"Good to meet you sir," the soldier saluted; the Doctor winced.

"Please don't call me sir," he said. "And please don't salute. Just Doctor."

"Yes s- Doctor," the soldier said.

"Can you tell me what's going on?"

"Join us," the soldier said, gesturing to the jeep. "I'll explain on the way back to the command post."

The Doctor nodded. Martha bit back a whimper, not entirely sure how she felt about riding around in an open-topped jeep in the nude, to say nothing of being under the eyes of all the UNIT men.
