Good Idea

Notes: Thanks to my wonderful reviewers! This is for you - enjoy! There is one more chapter after this, and I hope to write a one-shot sequel as well!

------
The first sign the Doctor had that anything was different was when Jack turned up to breakfast in a towel. Not that it was exactly out of character for the ex-Time Agent, who was exhibitionistic to say the very least, but a towel was even less than normal.

Still the younger man acted like nothing was going on, and Rose was only ogling Jack’s chest and giggling occasionally, so the Doctor let it pass. Whatever Jack wanted to wear was fine, so long as it didn’t bother Rose too much. Although, it was always good to expand the 21st century girl’s views on sex and the universe, there would have been no point in unsettling her. But as Jack in a towel seemed to have no real impact, it was fine by the Doctor. Jack had a nice body, and the Doctor was always up for appreciating art of lesser life forms.

That Jack was still in his towel at dinnertime was a little more worrying, but the Doctor let it pass again. The sight had only increased his want to touch the other man a bit. Nothing he couldn’t handle, and Rose seemed to barely notice. She was walking around with a dreamy expression on her face, smiling at everything that caught her attention: the Doctor, her plate, the table, the toaster. But not Jack. Very occasionally she looked at Jack and snickered. The three of them made polite conversation and no one mentioned Jack’s chest. Not even Jack.

After dinner though, the Doctor turned around, and Jack was standing a little too close behind him. They shuffled out of each other’s way awkwardly, trying to not collide. Jack’s hand brushed against the Doctor’s groin. The Doctor’s hand brushed against Jack chest, and tried not let show just how nice the contact felt.

About then he started to get alarmed at the smirk on Jack’s face, which was entirely too pleased with itself.

------

Next it was Rose. She was dressed fine at breakfast – and Jack was wearing actual clothes this time, but smiling like the cat that got the canary. Rose just looked like she was floating on air. He was starting to wonder what they were getting up to, but Rose was sitting very close to him, and kept bumping him accidentally, it was very distracting.

However, later, when he was trying to fix the TARDIS – they’d been stuck for two days and counting – Rose turned up having changed her outfit.

He slid out from under the console in the control room when she called for him. His first eyeful was off a pair of leather-covered legs that seemed to go on forever. The pants clung to her so tightly he wondered if she was going to have to cut herself out of them. Then he wondered what it’d be like to try and remove them himself.

It took him a minute to work his way up those legs, past the point where you could tell that she was very obviously not wearing any underwear, to see her… very skimpy top that just barely covered her wonderful chest. He swallowed and lifted his eyes to her face, which still hadn’t lost its dreamy look. It suited her, that look.

She asked him how things were going, and knelt down beside him, trying to peer into the gap he’d just come out of. The Doctor caught a good look down her top, which revealed a ridiculous amount of cleavage – far too much from his comfort. He had to move away very quickly as it was tempting to get closer to that very fine set of breasts.

Rose moved back, and touched his hand briefly with hers, disappearing very quickly after that. He wished she wouldn’t, she had a very nice bum that he would like to examine more closely.

-------

On the third day he started to have an inkling on what they were up to.

This time it seemed to be Jack who was wearing the same pair of leather pants that Rose had been the day before. On her they looked skin-tight. On Jack they looked like a second skin. They also showed, even more than the towel, just how well endowed Captain Jack really was.

The Doctor wondered if he’d have to have another cold shower. He’d needed one when he’d gotten up that morning after being haunted by dreams, which were very tantalising. The dreams had no doubt been prompted by the very odd behaviour – and clothing – of his companions.

Rose was wearing that smile that the Doctor was slowly becoming accustomed – but not immune – to, and Jack was watching the Doctor, with a slight smirk playing around his lips, his gaze hot. He didn’t take his eyes off the Doctor once during the meal, and Rose just sat their happily munching on her toast. It was unusual for her to be so quiet; usually, if she felt she wasn’t getting enough attention, she let everyone know.

Jack (who was shirtless on top of everything else), and the Doctor (who was fully dressed, thank you) ended up trying to get through the door at the same time. Somehow the resulting muddle ended with the Doctor with his back to the doorframe and Jack standing right in front of him, close enough that for every breath either took they brushed together.

About the time the Doctor realised he’d been standing transfixed, Rose pushed past on her own way through the door. The Doctor ended up trapped between the doorframe and Jack, whose gaze had turned decidedly hungry. Their faces were close enough that all it would take was one of them leaning in just slightly… then Jack licked his lips, and the Doctor had to fight his body’s natural reaction.

All of a sudden the younger man grinned, his normal cheerful grin, stepped back and followed Rose down the corridor.

The Doctor went to find that shower.

------

After that he wasn’t surprised to see Rose the next day, wearing what appeared to be a bikini top and a wraparound skirt.

She sashayed into breakfast giggling at something Jack was whispering in her ear. They were standing close together, Jack’s hand on Rose’s bare shoulder, her head tilted so she could hear him properly. The Doctor had to admit they looked very good together. Too good.

Without warning Jack shoved Rose into the Doctor’s arms. “Hey Doctor, Rose has something to tell you.”

This time it was Rose, shirtless, who was close enough to kiss. For a second, the Doctor didn’t even realise he was gripping her breast, until Rose nudged herself into his hands a little more. Through her bikini top her could see the tips of her nipples.

“What?” he breathed.

“Huh?” asked Rose who was staring at his lips, which was just as well, as she’d probably hit him for where he was staring.

“You have something to tell me?”

“I do?”

“Yeah,” drawled Jack interrupting. “About what we’re going to do after breakfast.”

“Oh,” breathed Rose, and the Doctor was painfully aware of the soft exhalation. “We’re going swimming.”

The Doctor gently pushed Rose back, and breathed deeply. “Don’t you need to wait an hour after eating?”

“I think we’ll be all right,” drawled Captain Jack. “Of course, if you want to come and make sure we’re okay…” It was an invitation. But to what the Doctor wasn’t completely sure, however his companions’ odd behaviour was a good clue. He really hoped they weren’t trying to seduce him.

Both of them were staring at him, like he was a particularly good meal at one of the universe’s best restaurants. Jack’s jeans had filled out slightly in the last few minutes, and Rose’s bikini top was still peaked.

Swallowing, the Doctor dredged up a response. “I, uh, have to fix the TARDIS.” They’d obviously been stuck here too long and his companions had developed a strange form of cabin fever.

Rose pouted, and that definitely wasn’t good for his mental health. “Well, if you’re sure…”

“I’m sure. I, uh, think I’d better go right now. The, uh, faster I, uh, fix it, the faster we can go, um, somewhere else.” Not one of his finer moments, but it’s a little hard to think clearly when your companions looked like they were going to jump you, and you weren’t sure you wanted to stop them.

He made a dash for the shower.

-----

After a long, cold shower, in which he spent far too much time wondering what it’s be like to have Rose kneeling between his legs, while Jack took him from behind, the Doctor headed for the control room.

His path took him past the swimming pool, and he was alarmed at the sounds coming from within. So he went to check them out, and wondered how in the hell he’d been so naïve. Really, he should have known better what – or rather who – sounded like that.

In the room, Jack and Rose had abandoned their swimming gear, and clothes in a pile by the door. In the pool, Jack had Rose pinned against one wall, her arms wrapped around his neck, his arms on the side of the pool.

Both of them were too involved in each other to notice the Doctor. Jack had his face buried in Rose’s neck, and Rose had her head thrown back, her eyes closed in ecstasy. Their panting and moaning echoed slightly in the room, judging from their movements they weren’t far off achieving a very good orgasm.

The moment that the Doctor noticed he was rubbing himself, trying to get some release of his own, he backed out of the room fast. But not before Jack and Rose’s cries sounded as they reached their climax.

He was in no way jealous. At least not in sense that he wanted one of them. He just wanted to be able to ease the frustration as they had. Preferably with both of them.

Yet he couldn’t do that. It was never wise to sleep with your companions – it tended to end in tears far more often than not.

And still he was heading back to the shower, where it would take more than just cold water to soothe him. In fact it required some self-handling before he was ready to head back to the consol room. Taking a different route this time, of course.

He needn’t have worried. Jack was already in the control room, making his own start on the repairs that needed to be done. The younger man was whistling cheerfully as he worked. The Doctor stood in the door, and glared, but Jack had apparently not noticed.

Rose was sitting on a bench. Lolling might be a better word. She looked indulgent, flicking through a magazine, that dreamy smile back on her face. She was back in her bikini top and wraparound skirt. One bare leg was hanging down, and the other was pulled up against her chest. The angle left the Doctor with little doubt that she wasn’t wearing any underclothes.

Now he had the explanations of what was going on with his companions. No wonder they had been so damned cheerful, despite being stuck for the better part of a week. They had been thoroughly enjoying each other’s company, while making it clear that they would be glad to have his.

Ignoring them, he got down to work and tried not to notice their hungry smiles.

------

Neither turned up to breakfast the next morning. The Doctor would have been worried, but he figured they probably needed so extra sleep after all their probable nightly excursions. Frail humans that they were, there was only so long they could go without proper rest.

As it turned out, he should have been worried. His companions were staging a coup.

When they both walked into the control room, the Doctor knew he was fighting a losing battle. When Rose and Jack kissed, he knew he was undone. When first Rose kissed him, then Jack kissed him, he went willingly.

Little Rose – who as it turned out, tasted so sweet – moved above him like some exotic pleasure nymph. Above her was Jack, acting as this was the single most mind-blowing experience of his life. That was enough. The Doctor lost track of time and space for a long moments.

He came back to the universe as Jack was helping Rose off him. The young woman snuggled between them, closing her eyes. She was beautiful, so stunningly beautiful, he couldn’t resist placing a gentle kiss on her forehead, and was delighted to see her lips curve into warm smile, and her sparkling eyes open.

“Still think this is a bad idea?” she asked sleepily.

“Consider me convinced,” he told her.

At Jack’s suggestion they moved their party back to the Doctor’s room. The Doctor carried a dozing Rose, who decided that she was going to nibble on his chest and nearly make him drop her, and Jack followed, his hand on the Doctor’s lower back.

The Doctor put Rose down on the bed and sighed softly. Then he turned to Jack and the two men shared a deep kiss, before curling up with Rose and drifting off on their own.

------

He awoke not long later, with his companions on either side of him. Rose deeply asleep and Jack’s fingertips lightly tracing his nipples. Already he was hard and ready for another session, and he could feel from behind him that Jack was in the same state.

The Doctor shifted slightly, as if in sleep, and was rewarded with a soft moan. Captain Jack had clearly woken up randy and decided to inflict a similar condition on the nearest bedfellow. Jack had been quite boastful about his exploits in the bedroom, and the Doctor had no reason to doubt the other man, in this situation it was certainly the more the better.

With a grin the Doctor turned over the face his new lover. Jack still looked a little groggy, not completely awake yet, his hair was tosselled and his cheek flushed rosy. Yes, both of the Doctor’s companions certainly were tasty prospects when woken up next to, and he just wanted to eat them all up, which gave him the idea.

He jumped a mile when Jack’s hands travelled down grasping him tightly, with a certain grip, that moved in just the right ways. The Doctor had been with a few beings in his time, here and there, with varying levels of experience. None of them had been as skilled as Jack Harkness, or as passionate as Rose Tyler. The two together made an electric combination and he made a mental note to set up a situation where he could watch them together, that glimpse in the pool had been nothing – he wanted to appreciate it fully.

Right now, he reached down and took Jack’s wrists, gently removing the other’s hands from their work, but bringing them up to be kissed so their owner would know how much they were appreciated.

“Uh, uh, not now, my friend, not now. Now we do something else.” Under the covers it was warm, but the Doctor didn’t mind, as intent on his goal as he was. He had an aim in mind and he fully intended to reach it.

Softly, he placed kisses on the insides of Jack’s thighs, darting his tongue between his lips to taste the skin there. Then slowly he allowed himself to become more daring, using his tongue to slide along Jack’s legs up to where they joined. Beneath him, his companion was stiff, every muscle taut. Although this was undoubtedly something that Jack was highly familiar with, he seemed to be wholly affected by it.

Jack jerked as the Doctor blew a soft breath across his lover’s hardened length, and a soft moan sounded from above. The Doctor let his hands creep up to hold Jack steady in place. But his fingers did not remain still, the caressed the captain’s flesh, firm and smooth, skin that bore careful exploration at a later time. He breathed again over the attentive tip, before tasting it, noting the difference in the areas of skin.

Feather-light kisses were placed up Jack’s not inconsiderable length (which the Doctor could but imagine inside himself, taking pleasure, demanding completion). Then the Doctor lightly took one of the sacs at the top in his mouth, rolling it around on his tongue, careful to pleasure only. Jack’s hips jerked, and his hands snaked through the Doctor’s hair holding his in place. The Doctor gently detached himself and moved on to the other one, tasting it, weighing it, determined to torture Jack for as long as it would take.

The other man was definitely moaning now. The sound was barely more than a hitched breath, but the Doctor knew well what it was, and enjoyed it for what it meant, loving the sense of being able to give pleasure in this way. He’d never been particularly attracted to males of any species, although he’d taken a couple to bed once or twice, and had never really enjoyed intimacy with them. Jack was different, and the Doctor found he was enjoying himself very much.

His lips trailed themselves down Jack’s length, licking, kissing, and even lightly sucking. He took his time, doing his best to drive his companion as close as possible to the edge without actually going over. The Doctor’s tongue would curve around his new lover’s length, with soft, firm caresses, that caused Jack’s fingers to tighten reflexively in what little hair the Doctor had.

Small droplets began to form on Jack’s tip, and the Doctor tasted them, getting his first sample of his companion’s essence. Last night he tried Rose, and this morning he was trying Jack. Several moments were spent concentrating on that tip, licking it until it was beyond clean. By this time, Jack’s hips had begun to stretch off the bed, and he strained for more.

The Doctor, feeling in an obliging mood, finally took Jack’s length in his mouth. Inch, by aching inch. Impatient, Jack’s hips bucked, but the Doctor kept up his pace, opening his throat, allowing all of his lover in, and there was a lot of the man to take in.

Once Jack was sheathed by his mouth the Doctor took a moment, moisting his mouth, before he began to slide up and down Jack’s length, slipping his tongue in synchronisation with his lips. Slowly at first, and picking up speed, as a restless Jack writhed above him.

Suddenly, Jack stiffened and called out something roughly as he released liquid into the Doctor’s mouth, shooting it down his throat. The Doctor took it without complaint, and then moved up to lie by Jack, who was looking very much like the cat that had the canary. A look that was becoming as familiar on his face, as the dreamy one on Rose’s.

They kissed deeply, the Doctor allowing one hand to begin to explore his lover’s buttocks, while Jack, gently squeezed his nipples, and rolled them in his fingertips. The Doctor became aware of a pressing need, of a decidedly uncomfortable sensation in his lower regions, something that definitely required easing.

Jack seemed to sense this, and with a grin that had turned completely wicked reached for something on his dresser. A bottle of lubricant. Jack undid the lid and squirted out a liberal amount, which he rubbed into hands slightly, before reaching for the Doctor’s length, and coating it in the stuff, his hot hands, massaging it in carefully, making sure to do a job well done.

Then without being asked, or hestitaion Jack turned over and put himself on all fours in a blatant invitation. The Doctor paused for a second at what was being offered, but was quick to catch on. He pressed a kiss to Jack’s mouth, hot and hard, grateful and wanting.

He mounted Jack and slid into him, with no trouble. Jack grunted slightly, but the Doctor entered easily enough. The fragile walls that now encased him we hot and tight and Doctor could hear the raggedness of his own breathing as he wriggled experimentally. Once he was comfortable – or as comfortable as one could be with a hard-on – he started to thrust. Again it began slow and picked up pace.

Underneath, Jack moved with him, encouraging his thrusting, and thrusting against him, creating more heat and friction. As the tension built the Doctor gripped Jack’s shoulders, and bent his head to place a kiss at the base of other man’s neck, before resting his forehead in that same spot.

As he approached his climax, he began to thrust with more abandon. Vaguely, he was aware of Jack’s encouragements and his own excited groans. His fingers tightened on Jack’s shoulders as white heat built, and then poured out of him into the other man. Stars danced in his vision and he cried out for Jack, once, twice, three times, and then collapsed boneless on to him.

He lifted himself out of Jack, and only then became aware of another set of moans, and turned his head to see Rose. She was watching both men intently, and her hand had disappeared under the covers, where it was quite obviously working on stimulating her.

Remembering the way she tasted, he started to move, diving back under the covers, as Jack moved to capture her lips in a kiss. As he did so the Doctor became aware that he was more than ready to go again with either – or both – of his new lovers.

It was after all the beginning of a brand new day.
