Go for a swim

Martha squirmed, awkwardly trying to keep herself covered.

"So, the way I see it, we have four choices," Martha said.

Focus on what to do, on planning, not on her situation. Still, Martha almost immediately regretted speaking as it made the red-faced Peri suddenly face her. Martha squeaked.

"We could, uh, stay here," Martha said.

"Let's not," Peri said, the twang of her accent even more pronounced when she was nervous.

"Or try climbing the cliff," Martha said, refusing to gesture.

On the opposite side of them to the lake was the nearly sheer surface, Peri took one look at it and shuddered; Martha squeaked again when Peri turned back to face her.

"No to that too," Peri said.

"Then it's either walking down the beach, or swimming through the lake," Martha said. "And I'm guessing you can't swim if-"

"I can swim!" Peri interrupted, slightly indignant. "Or- I just wasn't expecting to be dropped in a lake. Couldn't get my balance. And ok, I'm a little out of practise since travelling with the Doctor, but I could if-"

"You know the Doctor?!" Martha said.

"_You _know the Doctor?" Peri said, before giving an exhausted sigh. "Figures he'd be tied to this."

That... raised a lot of questions, but just then none of them were particularly prominent in Martha's mind. She hurriedly looked around the scene.

Of all the places to end up, why a beach? There weren't even pebbles, the biggest thing there was to hide behind was a grain of sand. She fidgeted again. She couldn't hope to even improvise clothing.

"I'd... rather go for the lake," Peri said. Her voice was high. "Don't want to walk around in the open like..."

Martha's eyes darted down on autopilot, suddenly noticing just how much of Peri's body was uncovered. Arms could only do so much.

Endless skin, her cleavage pressed together by her arms, the curve of her ass visible even sat down, long legs, and of course her bright red face; she squealed as soon as she saw Martha's eyes wander.

"Hey!" Peri said.

"I- I wasn't-" Martha said. "Just... are you sure you're up for swimming? I did just pull you out from the lake."

"I'm fine," Peri said hastily. "I told you. It was just... surprise. That's all."

Martha nodded, unconvinced. Still, worst case she'd just have to pull them back to shore.

Her gaze drifted then. Out over the clear water; it was easier than looking at Peri because oh god, did she look like that? Was she that exposed, that-

Burning with embarrassment, Martha looked out over the water. It was hard to make out details, but there did seem to be something a little distance away. Not much, a tiny pocket of land, but it was a goal. Once they were there they could rest, recover and plan anew.

Peri was the first to go into the water, seeming to have something to prove. She shuffled down the beach, dragging her ass along the ground and awkwardly fidgeting to move, keeping her arms crossed over her tits. When her feet dipped into the water, reaching the sudden drop in depth at the edge, she hooked them around to pull herself closer.

Then she slid in, and immediately started splashing. Without needing Martha though, she turned back and grabbed the land, pulling herself up and baring her tits for a couple of seconds while she inhaled; then she squeaked, crossing her arms again.

"Are you-" Martha began.

"Fine, I'm fine!" Peri said, blushing. "It was just an awkward start. Being like this is-" she shook her head. "Try to keep up!"

She turned around and that time moved much more quickly, though she had to flash her ass to do so. It didn't do anything for the redness in her cheeks, but she did stay above the water, pale ass perfectly visible through the crystal clear water.

Oh god, and this was meant to be the more modest of the options...

Martha squeaked slightly, but still moved closer. At least Peri wasn't drowning again.

Despite the fact it didn't seem like no one was watching her, Martha hurried as she dove into the lake. She squeaked at the first kick, hyperaware of the fact that she had no hope of covering herself like this, and that the purity of the water made absolutely sure anyone would see her, should they come across someone.

Hopefully it'd be just them.

She swam towards Peri, and together they made for the island.
