The Doctor and Rose are beamed to a alien planet to be held for hours in a room, naked. Meanwhile Jack and Mickey are stuck, naked as well in a separate room.

The Doctor woke up to a scream from the mouth of Rose Tyler. He'd just prefer it if she had screamed from pleasure or fright, rather than the surprise she conveyed as she jumped up and attempted to cover her naked body.

wait, The Doctor thought. naked body. Rose tyler is a few feet away, naked.

At that point he had look down and realized he too was naked. He could feel his face become red and looked up at Rose.

"Oh! Um…" The Doctor stuttered, trying to find something to cover himself and to distract his gaze from the beauty in front of him.

"There's nothing there. I've looked. We can either hide in the corners or we can ba-" Rose stopped abruptly as she too realized the person opposite was naked.

"What, Rose? Take the philosophical view and know that a body is a body and it shouldn't matter what they look like clothed or otherwise?" He said as he removed his hands from his crotch.

"Yeah. Uh, Doctor?"

"Yes Rose?" He said with a smile at her chest.

"You have a erection."

The Doctor looked down up at her down again and scrabbled around and ended up flipping the bed to it's side and hiding behind it.

"Doctor?" She said.

"Uh…" He replied.

"It's okay. You don't have to hide behind that bed."

"What?!" The Doctor popped his head above the bed.

"Come here." Rose demanded and pointed to the bed in front of her.

The Doctor got up, still erect and sat on the bed, where Rose had sat.

Now is as good as any, tell him. Rose thought to herself.

"Doctor I uh…" Rose had stopped because she saw him poking at his penis. "What the hell are you doing?"

"It's never done this before." He said as he looked embarrassingly at her.

"You mean become erect? You've never jerked off? Never got aroused?"

"What? Of course I have!" He said defensively, thought he had absolutely no idea why. "It's just that I've never had it that hard."

"What. Doctor…. What." She stumbled.

"Uh, sorry Rose, go ahead." He said apologetically.

"Doctor if we have to share a room on the TARDIS, can we at least sleep together?" Rose said awkwardly.

"Rose, if we slept in the same bed I'd have to have the TARDIS redesign my bed so we could both fit." He said, now getting fidgety. He wasn't used to sitting for longer than necessary. "And should we really be discussing this now? I mean shouldn't we be focusing on escaping?"

"We can do that in a moment, but what I meant was sleeping together together. Like sex." She said conveying a casual tone badly.

"Wha-? Jackie wouldn't approve!" He stammered.

"Since when did you worry about what my mum approved of? Last I checked she thought that slippers defied the 'laws of logic' and refused to wear them." She replied, finally more at ease. It almost seemed to her that if The Doctor was relaxed she couldn't be, and vise versa.

"And what about Mickey? Your boyfriend?" He said with a great mixture of distaste, love and unbelief.

"You saw on the monitor when we broke up. We're friends. That's all." She said as if it were the most common thing.

"How'd you know?"

"You had the picture of the spot where it happened still on the monitor when you left to go jump up and down in your room. Back when you had your ears." She laughed.

"Oh. What did happen to Mickey and Jack?" He wondered.

"One can only hope alive and not getting humped my Captain Harkness.
