Simultaneity

Now:

The first thought that came to Rose Tyler was that the two Doctor's cocks actually looked different.

The original Doctor's penis looked thicker, slightly more veiny. If she had asked, the Doctors probably would have said something about “genetic variance” or some technobabble. But today was not a day for that. She grabbed the original Doctor's face, brought it to hers. He tasted like her fiancee, but slightly grimier. More torn down, more weary. He fumbled underneath her touch, and she held him steady, keeping him still. His cock pressed against her leg, moving slightly.

She released him. He looked shocked.

“Rose, I--” started the original Doctor. She pressed a finger to his lips. There wasn't enough time for what he had to say. They only had one night.

She grinned at him. Then she looked back at her fiancee. Despite the fact that this had been his idea, she needed to make sure he was okay with this. Was he mad at her, for lusting after the other version of him?

He gave her a grin. A grin that said “It's okay, Rose. Have your fun.”

“Then come over here, and shag me,” said Rose.

Before:

“What are we gonna do for the honeymoon?” asked Rose. Her fiancee put on the thinking face she had come to love.

“Well, we could go on a trip. Though, really, once you've been to the Jovian Arch Party, nothing compares,” said the fiancee.

“Too bad the TARDIS is still growing. We could have gone to see that Arch ,” said Rose.

The Doctor, her fiancee, nodded. His face went serious, and his deep eyes looked at Rose.

“What?” asked Rose.

“Do you miss him? The other me?” asked the Doctor.

“Oh come on. I have him, right here. But even better, because I've gotten to know you even better,” said Rose. She kissed him.

He smiled, but his eyes were still thinking.

Now:

She grabbed her fiancee into a strong kiss. Behind her, she felt the other Doctor kissing her neck, rubbing her back. Her shoulders relaxed into it, and she moaned into her fiancee's mouth, grabbing him even closer.

“Enjoying your honeymoon, Rose?” whispered the original Doctor.
Her fiancee began to kiss lower. First her chin, then her neck, stopping at her breasts. Licking her nipples, he looked up at her, and winked. She winked back.

Then he trailed his tongue down to her stomach, then her pelvis, then lower. She moaned again, louder this time.

After:

“How exactly did you manage this without blowing up a hole in the universe?” asked Rose.

“Trade secrets,” said her fiancee.

Now:

Rose brought both the Doctors in front of her. In the darkness, they looked like twins. And suddenly, an  dirty fantasy crossed her mind.

“Kiss,” she said.

Both the Doctors raised their eyebrows, and rolled their eyes.

“Humans,” said her fiancee, with a smile on his face.

The Doctors kissed. First slowly, with trepidation, then faster. The original Doctor pushed her fiancee on the bed, kissing his mouth hungrily. Their chests rubbed against each other, as the original Doctor straddled her fiancee. Rose approached them, wrapping her arms around the original Doctor, and stroking the cock of her husband, while applying soft kisses on the original Doctor's face.

“You always wanted to do this with me,” said Rose to the original Doctor. She grabbed his cock, rubbing it slowly while licking him.

Her fiancee pushed the other Doctor off, accidentally flinging him off the bed.

“Ow!” said the original Doctor.

 The fiancee grabbed Rose, and moved till he was on top. He slowly entered her, looking her in the eyes the whole time. She pulled him closer, kissing him and wrapping her legs around him.

“Thanks for asking about me, guys,” mutterred the original Doctor on the floor. Rose extended a hand, beckoning him forward.

“We'll—uh--make it up to you,” said Rose, speaking between moans.

The original Doctor moved forward. Bending over behind her fiancee, he kissed her fiancee, and entered him from behind.

“Ow!” said her fiancee.

“Oh, sorry. Inexperienced with this sort of thing,” said the original Doctor, looking sheepish.
“There's lube on the desk, you know,” said her fiancee.

“How was I supposed to know that?” said the original Doctor.

Rose watched the image of the two Doctors arguing, and laughed at the absurdity. The Doctors looked at her, and began laughing themselves.

“Now boys, there's no need to quarrel,” said Rose, bringing them both in close.

Before:

Rose sat in her hotel room. She could just barely see the ceiling fan in the pitch black room. Her fiancee was out of the room, which was good for him, because she was pissed at him.

For his “wonderful honeymoon” idea, he had taken her to a history museum. Now, she liked history. She even liked it when he nerded out about historical inaccuracies. But that was not her idea of a sexy trip. She hadn't argued with him yet, because he was having fun, but boy, was she pissed.

The Doctor walked inside. Someone walked in behind him, and she couldn't see him in the darkness.

“What's going on?” said Rose.

The Doctor turned on the light. And the Doctor stood beside him.

“What?” asked Rose.

“Hello, Rose,” said the Doctor. His eyes looked tired.

There was such deep grief in the way he said it. Such sadness.

She knew immediately.

“How did you get to this universe? And why are you here?” said Rose.

“Well, the answer to your first question is complicated. I'll explain later. And as for the second question...” said the Doctor, looking at the other one.

“You didn't think I'd forget about your honeymoon present, right?” asked her fiancee, eyes twinkling.

Now:

Both Doctors were moving inside her now. (DP wasn't really her thing, but this was a once-in-a-lifetime event). The two Doctors kissed each other, and Rose blessed her stars.

Her body overloaded, and she came, biting her lip and gasping. After a moment, she stroked the Doctors off, watching them squirm and moan. The original Doctor came first, his semen coating her hands. As she licked it off, the original Doctor went down on her fiancee, who simply laid back.
Rose pushed the original Doctor off her fiancee, and went down on the fiancee, watching his eyes flutter.

“I love you,” he said to her.

“Love you too, Doctor,” said Rose.

After:

The original Doctor was getting dressed. Rose watched him, her arms entangled around her dozing fiancee.

“Thanks,” she said to the original Doctor. He looked over to her, and flashed his grin.

“Of course. It was fun, for me too,” he said. His eyes looked tired again, like he was so much older. What had he gone through, since last seeing her?

“Hey. Wanna talk?” she asked.

The Doctor shook his head. His smile became wistful.

“Not enough time,” he said. Then he walked out.

Rose was left awake by herself in the room. Her only company was the ceiling fan, and her sleeping fiancee.
