Jack's free hand ran along his bare spine and he felt the Doctor shiver uncontrollably.

"No, I'm…"

Jack grinned as the Doctor trailed off into a soft moan. He leaned in, kissing up the Doctor's neck, enjoying the needy whimpers that followed. He slid his hands up the Doctor's thin thighs and cupped the Timelord's very obvious erection through the thin material of his boxers. A startled gasp at that one, Jack noticed.

"Jack!"

Jack grinned at that reaction and rubbed teasingly at the Doctor. "Ah, I believe I've found what you're hiding." The line was cheesy, Jack knew, but it was fun to use nonetheless.

Suddenly, he was no longer the aggressor as a needy Timelord jumped into his lap, knocking him backwards on the bed. His lips were captured in a fierce kiss and the Doctor ground wildly into his hips.

Jack moaned into the Doctor's hot embrace and grunted as he felt himself pressed violently into the soft mattress. The Doctor thrust into him and Jack felt himself respond instantly. Fierce arousal shot through his body and every touch against his skin seemed to shock him.

"Doctor!" He called out involuntarily when the Timelord began divesting him of his clothes. The Doctor's hands brushed across him sensually and the fingers crawling over his body seemed almost like tiny electrodes. Vaguely, Jack wondered if that was a result of residual aphrodisiac or if the Doctor was just that good. That insignificant thought flew from his mind as the Doctor finally removed the last layers of their clothing and began kissing down his body.

Jack relaxed and let himself lay back, moaning quietly at the feel of the Doctor's soft lips on his bare skin. This felt like paradise. The sound of the Doctor's soft groans and the feel of a flicking tongue across his chest were beautiful feelings. Jack struggled to calm himself. He didn't want this to end sooner than intended.

Absorbed in thought, Jack didn't realize what the Doctor was up to until a tongue slurped around his nipple. He gasped and thrust blindly into the air, his cock brushing against the Doctor's stomach. Overcome, he surged upwards, toppling the Doctor backwards and straddling him tightly. The Doctor gazed up at him with half-lidded eyes and struggled against Jack's grip.

Jack grinned at the Doctor's helplessness and slid down lithely until he was at eye level with the Doctor's dripping erection. Ignoring the Timelord's pleading whines, Jack took a moment to admire. The Doctor's cock was thicker than some he'd seen, definitely longer than most, and small drops of precum glistened wetly at the tip. It was the single hottest sight Jack had ever seen. Obviously, the "stick boy" hid a lot under his suit and overcoat.

"What do you want, Doctor?" Jack purred softly, letting his breath slide across the head. He grinned as the Doctor twitched violently and writhed futilely, trying to get friction against something. "Come on, Doc. Tell me or you won't get anything." Jack sat back on his heels, slowly dragging a finger across the Doctor's tip, collecting precum.

"Please!" The broken scream echoed in the wide room. Jack felt himself twitch appreciatively at the sight of the Timelord arching his back and thrashing vainly against his strong grip.

"Tell me, Doctor." Jack ordered sternly. He waited patiently until the Doctor had locked gazes with him. The Doctor was practically begging with his eyes, but Jack smiled evilly and brought his finger to his mouth, lapping up the milky fluid hungrily. The Doctor's eyes visibly widened and then he threw his head back into the sheets and screamed wordlessly in frustration.

Jack ducked down swiftly and licked teasingly across the Doctor's head, relishing the Doctor's unique taste once again.

Another unintelligible scream.

Then…

"Please, Jack! Please! Touch me!"

Ah. That was what Jack was waiting for. He bent low and sucked the Doctor's cock into his mouth wetly. He teasingly licked along the shaft, tonguing the vein on the underside gently. He could feel the Doctor throb and twitch and he could hear helpless moans erupt from the Doctor wantonly.

Jack began pumping what little he couldn't manage to get into his mouth and the Doctor bucked up, thrusting his cock down Jack's throat. Jack carefully relaxed and let the Doctor do as he wanted. He knew it wouldn't last long with as worked up as the Timelord was.

"Jack!"

Jack sucked harder, pumping quickly and roughly.

"Agh! Oh, Jack! I think…! Oh!"

He redoubled his efforts, squeezing the Doctor tightly with his throat, urging him to let go.

The Doctor thrust once, twice more and came hard, shooting down his throat warmly. Jack swallowed convulsively, feeling the Doctor soften slightly in his mouth.

Jack let the him fall out of his mouth and slid up to lie next to the panting mess he'd created. He listened to the gasps and glanced over. "So," He began, "That was fun, wasn't it?"

"Jack." The Doctor gasped, "You're going to be the death of me."

Jack took a moment to enjoy the picture-perfect image of his Doctor, spread out on the bed, almost fully naked, looking completely ravished. He felt himself grow harder at the sight and realized he still had a problem he needed to take care of.

Already, the Doctor was blinking sleepily. Jack couldn't fathom how he could possibly be tired, but didn't want to disturb the man. He slipped out of the large bed deciding to make his way to the secondary TARDIS bathroom to deal with his problem.

However, a hand stopped him by falling lightly around his wrist. "Where do you think you're going?"

"Uh, bathroom." Jack gestured vaguely at his crotch almost embarrassedly.

The Doctor rolled over, shook his head, and pulled Jack forcefully back into the bed. Jack leaned into his embrace and moaned at the feel of the soft fingers caressing his chest and back. Immediately, a hot mouth covered his and the Doctor licked along his bottom lip.

Okay, unexpected, but very welcome. Jack arched his back, pressing into the Doctor, loving the feel of naked flesh against his. Hands were running down his sides, sometimes lightly, sometimes massaging gently. The Doctor deepened the kiss, running his tongue across Jack's own. The overwhelming sensations flooded Jack's brain and he groaned lowly into the Doctor's mouth.

A hand he hadn't been keeping track of brushed across his straining erection then and Jack whined in response. The fingers wrapped around him and the Doctor slid his grip up firmly. Jack gasped away from the Doctor's mouth and reached behind the Doctor, hanging on for dear life. The Doctor continued to stroke and then a hot embrace sealed around his left nipple. He felt the talented tongue flick sharply for a minute, then swirl slowly around the hard peaks. It was pure heaven.

Jack could feel himself near the edge and he grunted when the Doctor began speeding up his strokes. HE moaned three times in quick succession, wanting to warn the Doctor how close he was, but then the man twisted just so…

…and he was gone, spurting into the Doctor's hand, throwing his head backwards into the crumpled sheets, clenching his fists.

It took a moment for the world to return to Jack's senses. When he was finally aware, he realized the Doctor had shifted away and had wiped his hand on a towel on the nightstand. He rolled over, draping himself over the Doctor's body lazily.

He met the Doctor's gaze warmly. The man beneath him smiled hesitantly.

"I'm sorry. I just thought, well," The Doctor's cheeks burned bright red. "Since you were so nice to me, I thought you shouldn't have to just… head to the bathroom like that?" He ducked his head adorably.

"That was much appreciated, Doctor. Believe me. Please." No reaction. Jack grimaced to himself. It wouldn't do to have a depressed Doctor. That was a sure-fire way to collapse the universe. "Hey, Doc. Look at me." Brown eyes glanced up again. "I'm here to help you, but you know how much I like sex. Don't even apologize for returning things."

Jack kissed him quickly on the lips and rolled off, back into his own rumpled part of the bed. "Now, sleep. I know you're tired." It was a sign of exhaustion that the Doctor didn't even argue. He just folded himself into Jack's chest and burrowed under another sheet. Jack could feel the even, quick beating of the Gallifreyan hearts slow noticeably as the man fell into oblivion.

Jack sighed happily. Now, that was fun. Who would've guessed that visiting the TARDIS would lead to non-stop, week-long sex? He'd been worried about the Doctor's reaction to "helping him calm down" the first time, but, as he wasn't back in Cardiff or semi-dead, the Doctor must have enjoyed it, or at least appreciated it. Plus, there was that mind-blowing time not half an hour ago… If the Doctor was mad, it was the best kind of mad he'd ever seen. He breathed in deeply, folding his hands behind his head contentedly. For now, he'd sleep. The Doctor's light snores beside him lulled him gently into complete relaxation and he let his mind drift off…

A/N: Hope you enjoyed. More coming soon hopefully. Sorry 'bout the wait. I took on WAY too much this fall. Also, I have a general idea where this is going, but I'm not entirely sure of reactions and such yet. If anyone has any suggestions for small add-ins, I'd be happy to consider them. I like trying different writing thingamabobs. I've already added two suggestions into the plotline. Thank you! Hopefully I'll improve as I go. :]

Please review! I love 'em all!
