Chapter 1

o0o

Approximately eighteen hours after leaving Darlig Ulv Stranden (Bad Wolf Bay, really, because the Doctor didn't ignore coincidences unless he was very, very busy), the Doctor found himself in a rather enjoyable position. It had started out innocently enough, of course.

Pete had sent a zeppelin and off they went with barely a word to one another. The Doctor had shared amused glances with Rose when Jackie wailed on the phone to her 'baby', which as it turned out, was Pete and not Tony as he had originally thought. After that, the rest of the flight was spent in deep thought.

With his still-new human emotions racing through him, the Doctor had spent much of the trip wondering if Rose even wanted him. It was daft, really, not to mention completely exhausting, especially considering that if his calculations were correct, Rose was about to fall apart all around him in about ten seconds.

Human hormones were bloody brilliant, if he did say so himself. They had opened the door to the spare bedroom in the mansion and within 2.34 seconds, Rose's lips had been on him and there were hands in new places.

Which brought him to the current and most pleasing situation he found himself in. A wave of pleasure rolled over him and he wondered just why he hadn't spent two regenerations shagging Rose Tyler. Or, to be precise, being shagged by Rose Tyler.

"Doctor," Rose moaned from her position on top of him. A fine position, too. Her hands gripped the headboard and he really hoped Tony's room was the one down the hall and to the left.

She leant down a little bit which made the Doctor's view even better, if it was at all possible. He took the opportunity to capture Rose's rather delightful nipple in his mouth and gently caress her back. He felt his own tension mounting as Rose let out another spectacular moan.

"Oh Rose, you brilliant girl," the Doctor enthused as she let go of the headboard. His predicted ten seconds were coming up and as she leant back and forcefully grabbed onto his legs, he felt her clench around him. And it was that feeling right there, of being warm and encased totally by Rose that had the Doctor tumbling into the vibrant throes of ecstasy , following Rose into the wonderful abyss.

It took a full five seconds for the Doctor to come back to reality. He turned to Rose, who had climbed off him in the interim. She sported a fine sheen of sweat but the Doctor found himself rather elated at the sight of her.

"Hello!" he grinned at her, finding himself still a little short on breath (and kicking himself for not using his respiratory bypass previously in an effective manner when he still had it).

"Hello," she said back. "That was-"

"Oh yes," he agreed, shifting to make room for Rose under his arm. Without a moment's hesitation, Rose adjusted herself and pulled the duvet up around them. The Doctor supposed there was a chill associated with that beach in Norway that Rose Tyler, Defender of the Earth, could probably never shake.

Luckily for her, though, he was at least here to keep her warm this time.

A part of him wondered why he was immediately at ease with the entire stretch of domesticity in front of him. Here he was, lying in bed after a shag and cuddling and all he could think of was making sure Rose was comfortable. Naturally, he still thought of other things, like the small piece of his TARDIS nestled in the oversized pockets of his blue suit with pockets bigger on the inside or the fact that his ability to perceive timelines was slowly changing. He still thought about Donna and Jack and whether or not the other him was still wearing the brown suit.

Rose closed her eyes and shifted her head. "M'glad you're back."

He had seen many things in his near millennia but the sight of Rose's hair splayed over his arm and her face, her face still glowing from their wonderful episode of human entanglement was most definitely the greatest.

A loud and insistent thumping interrupted the Doctor from his deep and rather surprising sleep. Neither he nor Rose had moved which meant at least forty seconds of manoeuvring his arm (not his regeneration arm, at least) away from her. The door knocking continued and increased its frequency as the Doctor wondered how on Earth Rose could possibly sleep through such a thing.

He grabbed the bright pink bathrobe which hung proudly on the doorknob to the closet and without a thought as to who might be on the other side of the door in the Tyler mansion, flung it open.

He immediately looked down to find a six-year-old Pete Tyler doppelganger. "You're the Doctor," he stated matter-of-factly.

The Doctor grinned. "Glad someone's convinced!" The Doctor stuck his hand out.

"Pleasure to meet you! I'm the Doctor!"

Tony eyed the Doctor's proffered hand with suspicion. "Mum said you are Rose's boyfriend but I don't believe her. Rose doesn't have boyfriends."

And there he was, the Oncoming Storm with one heart, wearing a pink bathrobe that was displaying his rather fetching knees and grinning like an idiot. "Well," he started, running a hand through his hair and crouching down to Tony's height. "Maybe you should listen to your mother. Knows a lot, she does. Well, about this anyway. Well, mostly..."

He waited a moment but Tony stuck out his hand. "I'm Tony."

The Doctor grinned and accepted his hand, shaking it firmly. "Tony Tyler. The man, the mystery. I'll tell you what, Tony Tyler, of the Tylers, I'm going to go find Rose Tyler, also of the Tylers and let her know that Tony Tyler and the Doctor are now official friends. And you, Tony Tyler of the Tylers, specifically of the Tylers of this house, can go and eat your breakfast."

Tony pondered his conundrum for a moment. "Okay," he finally decided. "Maybe I'll see you and Rose later?"

He stood, stretching his still-displayed knees, careful not to lift the pink robe too high. "Oh Tony, you can count on it."

Satisfied, the mini-Tyler bounded off down the hall. It was bizarre, really. He had been in Jackie Tyler's home and it occurred to him that she now had spare bedrooms with hallways. Human life, he thought, never ceased to surprise him.

Now that his meeting was done and dusted, his thoughts wandered back to the sleeping pink-and-yellow woman in the bed, who had hardly moved during the night. He scanned the hallway a last time and closed the door, making sure to create as much noise as possible.

Rose always did sleep too long.

He recalled evenings where he would walk past her room, urging the TARDIS to orchestrate a rough landing or sound an alarm. She never would and he would wait ever so impatiently for her to start their next adventure.

That was when they had all the time in the world between them. Today was the first day of the rest of his one human life and he intended to make the most of it, which he could not do when Rose, who was still tucked under the covers, not a scrap of skin showing, was sleeping.

That would not do.

So the Doctor did what any normal half human, half Time Lord would do and pulled back the covers, expecting the rush of fresh air to shock Rose's pink-and-yellow naked body into waking up and spending the day in Pete's World together.

Except Rose didn't wake up, she only stirred and spread an arm onto the side of the bed where his one-heart body should have been, which was completely lost on the Doctor.

Because where a flat stomach was last night when he had trailed a dozen kisses, was an unmistakable rounded pregnant belly.
