Jack sneaked up behind the Doctor and gave him a gentle tap on the shoulder. The Doctor nearly jumped and screamed with shock.
"God damn it Jack!" the Doctor turned around to his snickering boyfriend, "How many times did I tell you not to…"
Jack wrapped his hands tightly round the Doctor's neck and pulled his head towards his. He kissed him passionately and licked the Doctor's lips impatiently before forcing his tongue inside his mouth. The Doctor's attempts to stop Jack from gaining control over his body were useless. After a short struggle he gave in.
If Jack wanted to have him right now, he'd get him right now.
Jack left him no choice. He never did.

The Doctor's mouth stayed ajar as Jack licked the Doctor's teeth and tried to force its way deeper and deeper into his oral cavity.
Suddenly he pulled away from the Doctor. The grunting and gasping of the Doctor seemed to be even more of a turn on.

"Turn around" Jack's words got swallowed up by his constant panting.
Jack clasped the Doctor's hips and forced him down on the floor, rolling around and stroking his hair like mad. Eventually Jack stopped while he was on top of the Doctor and pressed his knees against his thighs, forcing the Doctor to open them slightly.
"I never should have given you a key to the Tardis" the Doctor moaned and grasped Jack's hands.

"Please be patient" mumbled the Doctor while he tried to free himself from his garment.
"You know that I won't be" smiled Jack.

He ripped the clothes off the Doctor's body but only undid his belt and pulled his trousers down to his knees.
Jack let the Doctor spread his legs for him; he enjoyed it when he surrendered to his desires.
The Doctor placed his feet on the floor and slipped towards Jack's crotch.
Jack leaned over him and tried to kiss him once more before entering but the Doctor evaded his touch.
"Jack, please" whispered the Doctor; his voice was trembling with fear "Be careful with me."
Jack chuckled and forced his tongue down the Doctor's throat. Then he kissed his neck.
"I love to hear you beg."

Slowly Jack slipped towards the beloved body, rubbing his crotch on those soft thighs, feeling him skin on skin. Oh, the Doctor had a divine body, thin, lightweight... and a goddamn tight hole.
Jack felt the throbbing of his cock increasing at the mere thought of it.
He entered the Doctor's body abruptly and pressed his hands over his mouth. He didn't want to hear him scream right now.
He could still save it for later.
Jack knew that he demanded much from the Doctor. The penetration had always been a great physical exertion for the Doctor as well. Although they were about the same size, and in fact Jack didn't like to think about it, he must have weighed twice as much as him. Therefore he didn't like being on top of him. Jack had always been afraid that he could have hurt him.
At least more than he actually wanted to.

Jack grasped the Doctor's shoulders and increased the speed slowly, moving the upper edge of his hip bones monotonously against the Doctor's. The Doctor had such a delicate and small pelvis. He had always been fascinated how the body beneath his own shivered and writhed, how fast and strong the vibrations and contractions became the more violent and painful he penetrated him.
Jack had already achieved the desired effect. The Doctor's hearts were racing and couldn't speed up anymore. He figured he had stimulated him enough.

The Doctor groaned while feeling Jack's hot semen gushing out of his tight hole. He closed his eyes; his face was distorted with pain.
Jack released his grip and moved carefully backwards, pulling his limp member slowly out of the Doctor.
"Jack, I told you I don't like that" hissed the Doctor.
"Just do it quick."
"I never will." Jack smiled.

It had been three months since the Doctor had agreed to give him a key to the Tardis. Jack loved sneaking into the Tardis, even if the Doctor wasn't there. He felt honoured to be allowed to step into his home, his secret hiding place every time he wanted to.
Nothing was more intimate to the Doctor than the Tardis.

Jack rolled the Doctor from his back to his stomach and stroked his hair. The Doctor sighed and pulled on Jack's arm. Jack understood and lay down beside him. He felt that his pants were tightening again and therefore would have much more enjoyed it to place himself on top of the Doctor. But there was still the weight... He was afraid of the Doctor coughing or gasping for air and he knew that in that case he would feel fat.

"You can't be satisfied, can you?" sighed the Doctor when Jack pressed his hips against the Doctor's. Jack laid and arm around the Doctor and nibbled on his ear.
"You've got a one-track mind" mumbled the Doctor and turned his head towards Jack: "and I'm sorry, I'm really sorry but I'm afraid I can't help you with that."
"Of course you can" replied Jack, "don't put your trousers back on." He laughed and places his hands on the Doctors' hips; even the Doctor had to smile.
"I'm sorry, Jack" gently the Doctor pushed his hands aside "But I'm freezing." Jack nodded and watched the Doctor dressing himself dreamily.
Soon Jack would propose to him. He just had to wait for the right moment.
But it wasn't that easy with the Doctor.

If he was in the mood for sex Jack would seize the opportunity and wouldn't try to create a somewhat romantic atmosphere. And if the Doctor wasn't in the mood... well, then Jack had to convince him that he actually was.
Jack had to admit that he was pushing the Doctor a little bit too hard. And not only physically. He didn't know what the Doctor wanted; what he liked, what he enjoyed... Sometimes he got almost the impressions that Gallifreyans weren't born for having sex. But it could have been the Doctor only, too.

"The Tardis' pretty chilly" mumbled Jack and kissed the Doctor's neck after getting to his feet again.
"I don't care" replied the Doctor, "as long as I know that there's someone here to keep me warm..." He snuggled with Jack and put his arms around his chest again. The Doctor felt save in the arms of his lover. He felt needed and loved.
He wished the moment to last forever.

That was when Jack's phone rang. The Doctor sighed disappointed and let go off his lover. Jack started fumbling with his trouser's pockets and picked it up while leaving the Tardis, whispering to the Doctor "I'll be right back..." before answering the caller with a military undertone in his voice.
He didn't like getting disturbed while spending time with the Doctor. With HIS Doctor.

The Doctor sighed and patted some levers of the Tardis.
He knew that it must have been someone from Torchwood. And he hated Torchwood. Not only for destroying the romantic moment. He had hoped that Jack would give up his work there for him. But the dear Captain refused to quit, although the Doctor had hold out the prospect of letting him travel with him. Jack was looking for doing those things, really, but in his spare time only.

The Doctor looked at the screen and the notes in Gallifreyan he had left there. Some of them were really hard to read. He didn't even know what he had tried to write down.
He sighed.
He had really hoped that the key would have been more important to Jack. He had given Jack an entrance key to the Tardis, what else was there to say? He loved him! He wanted to be with him. Just the two of them, in here. Forever.
He chuckled. That sure was romantic. Maybe Jack rubbed off on him.
Alright, he had to admit it, he did. And in more than one way...

The door of the Tardis opened.
The Doctor scribbled a little note to remind him that he really should improve his Gallifreyan again. He could barely read his own handwriting and he surely wasn't as well-versed in grammar as he used to be.
"Didn't take that long, did it?" mumbled the Doctor.
The screen went black. The Doctor looked up. The lights were fading. The power in the Tardis was down.

"What did you...?"

He broke off in mid-sentence. Someone wrapped his fingers around his neck and choked him before forcing him down to the floor.
The Doctor's face was brutally pressed against the ground, which made it practically impossible for him to open his mouth.
One hand of the invader was on his neck, with the other one he tried to undo the Doctor's belt and undressed him.
The invader breathed down his neck and panted:

"I'm so sorry..."
