Chapter Text
One hand on the console and his other fumbling clumsily with an old tome, The Doctor stood, knees buckled and brow furrowed. He gazed again at the title etched in golden Gallifreyan text across a deep crimson cover: A Nychthemeron of Taking.
The Doctor's thumb found purchase in the old parchment and opened to a point midway through the book. He studied the words quickly, but found it difficult in his current state to understand the material.
“Table of contents, table of contents...” he shut the book back to the front cover and opened it with renewed determination.
Your Inaugural Heat........ Page 6
The pages felt thin between his fingers and they rippled as he turned to the target.
Your first heat may descend upon you at any point between your nine-hundredth and eleven-hundredth year… if denied or cruelly suppressed, it may awaken impulses of an intense and ungovernable nature…
The Doctor skimmed and turned another page, unable to dissect more than a few key phrases.
Most Time Lords enter their heat for a span of roughly twenty-four hours (as suggests the title). Though certain accounts speak of episodes enduring as long as seventy-two, the longest uninterrupted heat ever recorded persisted for thirty-five hours, ten minutes, and ninety-four seco—
The book closed with a hard slap. Over 24 hours? He tongued the inside of his own cheek, then bit his bottom lip. The lines on his forehead deepened as his face twisted into worry, then deep thought. Will that be too much... even for...?”
With shaky hands and held breath, the Doctor eased the TARDIS closer to the one person he hoped would be willing to help. Sweat dripped from his brow as he tried to concentrate on steering and not the growing need deep inside. The ache was like nothing he had felt before, forcing every muscle in his body to tighten.
The Doctor thought back to everything else he had been told about where he now found himself, deeply in heat. How naive he was, to think it was all lies or that he could escape biology, or whatever other reason he had thought that this would not happen to him.
But, truly, how could he have known that a race as sophisticated as the Timelords could actually become something so... animal. Pain coursed through every fiber of his being and radiated outward and then back inward towards his throbbing groin. He released a low growl and inhaled.
The TARDIS whirred and worbled, restless and uneasy, knowing the Doctor's current target.
“I know, girl,” he rubbed her softly. “But... it has to be him.”
The TARDIS made a sound of understanding, but reluctance as it throttled through the vortex.
~*~
Captain Jack Harkness had been having a very average day, indeed. Nothing at all remarkable had happened at Torchwood in weeks. In fact, it was almost remarkable how unremarkable it all was. A sigh formed deep in his chest. Of course, he thought, unremarkable does beat dying.
A familiar sound caught his attention and quickly grew louder. The sound of the universe. He expected to see the blue box materialize somewhere nearby, but he found that it appeared around him instead. The familiar smell of iron and the hum of the time vortex engine welcomed him and he felt a tinge of excitement as he took it all in.
Then again, there are some adventures worth dying for... Harkness smiled and turned on his heel. “I knew you couldn't stay away from me old girl,” he gave the console a stroke and it sputtered in protest.
“And you!” Jack exclaimed. As he saw his Doctor sweating profusely glaring a hole into the floor, Jack's smile faded and he took a step closer, “You alright, Doc? You've... seen better days...”
“Just... brilliant, Captain.” The Doctor winced. His knuckles went white as he braced himself against the metal railing. He slid the book across the floor with his foot without raising his eyes. It hit Jack's boots with a dull thud and he looked quizzically at the text on the cover.
“I shouldn't have to remind you... this box of yours won't translate that,” Jack chuckled, paused, then continued after not receiving a response, “Never really understood why, but-”
“It's... a text about the Gallifreyan mating season,” The Doctor interrupted with a heavy sigh.
“I mean, I don't know much about Gallifreyan animals, but I do know quite a bit about mating if that's why you brought me here,” he joked, still puzzled, but intrigued. He had never seen the Doctor like this; so out of sorts, so.... glistening, and tense.
Jack cleared his throat and his mind of the thought. His friend needed him for something and he had to know what it was to help. The soft clunk of his boots on the ground echoed through the empty console room as he stepped cautiously forward.
“Jack, it just keeps getting worse. I don't think I have a lot of time before...well, from everything I've read – I don't know if I'll be in full control of myself,” The Doctor paused and glanced at the Captain. He immediately regretted allowing himself the view as heat radiated through him just at the sight. He wanted to be buried inside the Immortal, wanted to smash into him with reckless abandon over and over until they both fell apart. It was getting more and more difficult to fight that urge with every second.
Suddenly Jack understood, although the Time Lord was too embarrassed to say outright. The Doctor... My Doctor is the animal. And it's his mating season. Waves of excitement and concern hit him both at the same time.
“Doc,” Jack looked at the Doctor, who was looking down at the ground again. Jack waited for a few seconds before continuing, hoping he would look up at him. He was tempted to place a finger under his chin and slowly guide the Doctor's eyes towards his own, but, that might be moving a bit too fast. “I can't imagine anything you could do that would be unwelcome,” Jack smiled around the words and let his mind start to imagine the doctor losing control... for once in his life. God, that would be beautiful.
The Doctor winced as though he did not believe that. Even he didn't know what he would say or do... or want in this state. “I... I won't be myself, Jack. I couldn't bare it if I...”
Jack knew his meaning even though he left it unsaid. The Doctor had caused him so much pain, and so much joy it was difficult to know which feeling this encounter would leave him with. Still, he doubted there was anything that hurt as much as being left again.
“I'm perfectly capable of handling whatever you have in store for me, ” Jack said reassuringly. “But - If you're really worried... we could always... restrain you.”
The word restrain caused the Doctor's mouth to dry in an instant and he looked up to finally make eye contact with Jack. “I.... I...” he didn't even know what he was trying to say.
Jack held the doctor's gaze, but noticed in his peripheral the Doctor's hand was in between his own legs. He wasn't sure if the Doctor even noticed until he said “Need a little help there, Doc?” and gestured.
“What?” He looked down, and his face froze, but his hand stayed nestled there, rubbing gently. “Why can't I stop, Jack?” The Doctor moaned out. “I'm... I'm trying to stop. Please... I”
Jack's hand reached for the Doctor's wrists and he firmly maneuvered him so both his arms were over his head. Quickly, he reached for his belt with one hand, while holding both the Doctor's wrists in his other, and wound the leather taut around the Doctor's wrists. Clearly, he had done this before as he didn't break eye contact while securing the belt. Firmly grasping his captive's wrists, he pushed towards the wall, pinning the Timelord securely against the cold metal.
The Doctor was sweating profusely, and practically panting as Jack addressed him again. “I... while this is... quite possibly the hottest thing I've ever seen. I can't.” The Doctor writhed his hips, seemingly not hearing the rejection and focusing on regaining the friction he felt before. His groin found Jack's thigh and he let out a moan as he rolled his hips, trying his best to grind into the Captain. Jack forced himself to repeat more directly,“I can't take advantage of you in the state you're in.”
“Jack...” The Doctor was breathless, but he was cognizant. He couldn't control his motions, but still had a mostly clear mind. “I came here because I trust you. And, yes if this wasn't happening... I probably wouldn't be here.” The Doctor paused and threw his head back slightly, letting out a frustrated moan as the Captain shifted away. “Please, it's really starting to hurt, Jack.” The Doctor's head lolled back down and his eyes found Jack's stormy gray irises boring into his own. “I wish I could explain more, but I can't do this myself and... I need release.”
With no friction, the Timelord's arms began to quiver above his head. He was flushed red and sweat was beading all over his face.
I can't just leave him like this, Jack thought to himself, his eyes fixed on the beautiful creature writhing and moving to press against him.
“Alright Doc.. I'll help you,” Jack agreed, still uneasy about taking his friend in such a vulnerable state. Visible relief washed over the Doctor's face and he flashed a brilliant, but pained smile. “You owe me, though,” Jack winked, turning back to his playful demeanor.
“Thank you,” The Doctor choked out.
Jack shifted back to his previous position and immediately, the Timelord pressed his hard cock back into it's former resting spot on Jack's thigh. It's hard as a rock now. Was it this hard before? Jack thought, Is it painful for him to be this hard. Does he feel that same ache that I've felt on sleepless nights thinking about him? He wondered.
“I... need... more.” The Doctor huffed out. Jack could feel the Doctor's wrists tense and push slightly in a feeble attempt to remove them from his grasp. Jack maneuvered his stance again so only one hand was pinning both wrists to the wall and his other hand moved to the Doctor's chin. He poised one finger beneath it and closed the gap between their lips.
The Doctor took no time adjusting to the kiss, hungrily pressing his lips back against Jack's as much as he could manage. When Jack's tongue entered his mouth, it was a strange sensation to him, but he welcomed the feeling. He could feel as Jack pulled away a slight amount, and without fully meaning to, bit down on the Captain's bottom lip, trying his best to keep him close.
The Doctor huffed as Jack's lips fully left his and his spare hand went from the Timelord's chin to thumb the mark on his own lip. “I didn't take you for a biter,” Jack smirked.
The Doctor glared at him, he wanted to say I didn't take you for a tease, but thought better of it. It would only encourage him to tease more. Instead, he said “Jack, every second that you're not inside of me... is painful – it feels like I'm on fire. Please Jack.” If this were any other day, that would have made him feel utterly pathetic, but right now, he didn't have room for shame. This burning need was consuming him from the inside.
The smirk left Jack's face and a hungry look replaced the playful expression. “Doc... fuck can you say that again?” he muttered as he closed in and found a spot to nibble on the Timelord's slender neck.
A spark traveled from the Doctor's neck to his groin as his hips rocked more erratically against the Captain's thigh. “I need you inside of me,” he repeated. He heard Jack growl against his neck, the animal awoken inside him as well.
“Keep your hands above your head, or I stop,” Jack snarled before releasing the belt. The Timelord nodded, mouth agape, showing that he would try. Jack took a step back and waved his finger in a circular motion, gesturing for the Doctor to turn around.
The Doctor complied eagerly, and placed himself with his elbows against the wall, bent at the hips, and legs spread. He felt Jack move his long coat to one side, then grab his trousers and boxers so they both came off swiftly in one move.
Jack eased himself into a squat, so he was lined up with his mouth right at the Timelord's entrance. He wasted no time and almost in an instant the Doctor went from feeling a breeze, to hot breath, to a warm wet muscle teasing him. A series of moans escaped without permission, but he decided there was little use in trying to regain control. His legs were already shaking and Jack had barely begun.
The Captain wanted desperately to keep eliciting every delicious noise he could, but he pried himself away. He received a needy groan in response. “Sorry, Doc.”
“Fuck's sake, Harkness” The Doctor growled curtly as he straightened up to a standing position. Arms still over his head with the belt snug around his wrists.
Jack smirked, if this was any other meeting, he might tease just a bit more, take his time, really make the Doctor regret snapping at him. But he was brought here to help the situation, not make it worse. “Well excuse me for trying to make sure your legs don't give out.”
The Doctor rolled his eyes. Jack was right, they probably would have buckled and he would've fell to his knees, but that wasn't exactly a priority right now – making sure he was comfortable. “You're not excused.”
“You know,” Jack chuckled, grabbing some cushions from a nearby couch, “I preferred when you were insatiably horny and pleading for me, rather than this snappy brat thing you're turning into.” Jack paused and added cheekily, “Remember your manners, Doc.” He popped the cushions down next to the Doctor's feet.
The Doctor lowered himself onto his hands and knees on the cushions. He growled a bit when he realized the discomfort of the leather around his wrists, and suddenly he did care a little about comfort. “Jack,” it came out as more of an angry snarl than he meant for it to, “your belt...”
Jack undid the belt quickly and took the opportunity to remove the Timelord's jacket and top as well. The fabric was coated in perspiration, and he sighed as the weight of it unstuck from his skin.
Before the Doctor could get too used to his freedom, Jack twisted his wrist behind his back like a prisoner and pushed, his face met the cushion in a quick movement. The Doctor turned his head to the side “You could WARN ME!” he yelled, more in surprise than anger.
“Where's the fun in that?” The Captain grinned and took his captive's other wrist, fashioning another restraint in an instant. Satisfied with his makeshift handcuffs, he slid his hand between the Doctors newly exposed shoulder blades. He took a small bottle of lubricant from his own pocket and slicked his fingers.
Within moments, Jack's tongue was working the Timelord's hole again, rimming around his entrance and making him shake and moan once more.
He knew the Doctor needed release and not too much teasing, so more quickly than he wanted – for the poor Doctor's sake, Jack worked a finger deep into the desperate Timelord.
“Jack..” The Doctor moaned out in between gulps of air. “I can't wait any longer. Please, Jack”
Shaking and sweating, the Doctor moved his thin hips, fucking himself with Jack's finger. The Timelord's cock pulsated with want as he moaned wantonly, “Please, Jack.”
In all of Jack's sexual escapades, and there were a lot, he'd never seen someone come this undone, want him this badly. It was incredible to see the Doctor - a man who had conquered civilizations, seen worlds begin and end, watched stars burn to dust - be this same man pleading with him now.
Jack added a second finger and a groan emitted from the Doctor which was somehow both grateful and steeped in frustration. The Doctor quickened his hips, bucking faster against Jack's fingers. With his spare hand, Jack slicked his own member in preparation.
“Fuck,” Jack moaned as the Doctor's entrance pulsed around his fingers. He wanted badly to feel it do the same around his cock. The unending string of moans rang in his ears as he grasped the Timelord's hip firmly, “Doc, stop for just a sec...”
The Doctor reluctantly obeyed, wincing as he slowed and then stopped his hips. He felt Jack's fingers leave him and thought the emptiness may drive him mad. But Jack was slowly thrusting inside of him before he could say anything in protest.
Jack grasped at the loose end of the belt, tightening the restraint around the Doctor's wrists and using it to pull himself further inside. The Doctor was panting and making slight moans, unlike the ones before, as he tried to accommodate the change. There was a bit of pain, he noted, and he'd probably feel it in time, but right now, he needed more-even if it hurt. Especially if it hurt.
As Jack sheathed his cock inside the Timelord, he moaned “I've wanted you for a long time, Doc.”
“Mmmmmm” The Doctor responded, his eyes rolled back in his head as he took the Captain's full length for the first time. He didn't have words, barely had thoughts other than “Fuck me, Jack.” He wasn't aware that he whispered it aloud, unable to keep it inside his mind.
Jack moved his hand from the belt to the Doctor's thick brown locks and grabbed a fistful of his hair. He forced the Timelord's head upward as he pulled out near fully and then thrust back in again, hard. The Doctor screamed with pain and delight. He moved his hips as the Captain lingered a bit longer, unmoving, fully inside of him.
Jack thrust backward and fully forward again, both hands entangled in the Timelord's hair – yanking his head into position and arching his back beautifully. “I want so badly to savor you,” Harkness moaned. He could already feel the Doctor tightening around him and his breathless gulps of air told him how close he truly was. It would be torture to drag this out much longer. “You fucking owe me, you horny bastard,” he chuckled a bit to himself.
“Anything you want,” The Doctor whispered breathlessly in between moans. He was completely gone from this realm, if Jack tried to hold him to it, he may not even remember making the promise.
Jack picked up a rhythm, thrusting in and out firmly and deeply, but not as quick as the Doctor would have liked quite yet. The Timelord's hips moved by themselves, meeting every thrust and guiding Jack to a faster speed.
Jack readjusted his grip on the Timelord's hair so he held the same position with just one hand and pulled firmly as he matched the Doctor's fervid, desperate pace. The steady slap of skin against skin reverberated through the room, joining the constant mechanical hum.
Jack moved his other hand to find the Timelord's cock. It was slick with pre-come and badly needing to be touched. As he gripped it in his hand and stroked lightly once, the Doctor exploded in a cacophony of moans and yelps. That was all he needed.
As the Doctor finished on the cushions beneath them, Jack gave into his own release and filled the Timelord's pulsing entrance with his come.
Jack released his grip on the Doctor's hair, “Better now?” He asked, breathing hard through his nose.
The Doctor moved beneath Jack quite gracelessly and brought himself to a seated position against the cool wall. It felt amazing tingling against his skin in the aftershocks of orgasm. “Jack... there's something I haven't told you.”
“There's probably a lot of things you haven't told me,” Jack retorted dryly. “Just let it be for another day. We had fun didn't we? No need to worry about anything else right now.”
“Jack..” He met the Captain's eyes with a serious stare. “It's important..”
“Alright,” Jack sighed, “but remember you owe me. This isn't the time to be asking me for more favors.” His tone was faux-serious, but he couldn't help but smile around the words, giving him away instantly. Of course, he'd never hold the Time Lord to anything he said, this wasn't actually a favor, but Jack never could resist teasing.
“So... this... Time Lord breeding, mating, whatever-you-want-to-call-it... thing-”
“You being incredibly ungodly horny, you mean.”
The Doctor swatted away the snide interruption and continued, “it's... for 24 hours.” At least 24 hours, he thought to himself, but didn't dare add aloud. The thought of this going on longer made his skin prickle.
"Ummmm,” Jack paused. “Doc, I don't know if you know this, but... you're not exactly acting like you 'need me inside you' right now.” The Doctor looked unamused by the air-quoting of his previous pleas.
“Like humans, Timelords have a refractory period. Of course ours is much shorter – roughly 5 minutes in normal circumstances,” The Doctor said matter-of-factly. “These are not exactly normal circumstances, so I can't be sure, but if the rules are the same, we have about 4 minutes until I am-”
“Begging for me,” Jack interjected, not caring what words would have replaced the intrusion had the Timelord been allowed to finish his thought. Nothing was better than the raw want he just had a taste of. 5 minutes couldn't pass soon enough.
The Doctor's gaze fell, he not dare look up at the Captain's smarmy overly-confident face as he said, “If anyone could take a full 24 hours of this... it's you, Jack. That's why it had to be you.”
Jack was grinning from ear to ear, “So you do need another favor after all then?”
The Doctor slowly lifted his gaze, and scowled a bit when he saw the Captain's grin. He rolled his eyes and sighed, giving into Jack's easygoing retort. Allowing himself to smile a bit in response, he replied, “Well. I suppose I was hoping you'd think of it as mutually beneficial...”
“Hmmm... maybe...” Jack thought for a moment, “especially if this next go round we do it my way.” The Doctor worried his lip as Jack grinned and leaned close to his ear, continuing, “That is... I'll be taking my sweet time. And you won't finish until I let you.”
They did have a full 24 hours to kill after all, but Jack felt a bit cruel for bringing it up when the Doctor didn't answer straight away. Of course, he wouldn't make anyone do anything they didn't want to; but in the heat of the moment, he was almost sure he would receive an enthusiastic 'yes.' Maybe he had read the situation wrong. Jack waited for his Doctor to regain composure before he backtracked.
The Doctor felt hot again, a coating of sweat still all over and his spend on the cushions between them, Jack's come still warm and dripping down his thigh. He still had a few minutes, but he could already feel his cock twitch with anticipation. “Okay,” he managed to choke out.
Jack beamed and stood up, he gestured for the Doctor to do the same. He moved quickly to untie the Doctor's hands from his belt; his wrists were a welted red underneath and Jack took care to be gentle now that the pain was sure to be more noticeable in the absence of pleasure. “Be very obedient and I may not need to use this again,” Jack teased. “Now, let's find some more comfortable accommodations. Lead the way!”
The Doctor looked sheepishly at his clothing on the floor and moved to fetch it. Jack intercepted, “No need for that. It'll all be off again in a minute anyways.” The Doctor knew he was right, but it still felt strange being fully naked and walking around his TARDIS. He felt her judgement through their psychic link and had never felt more exposed. Even showering in the TARDIS drew shame from him and he would often take trips to private bath-houses or isolated natural water features to avoid it.
Jack took off his coat and threw it around the Doctor's shoulders, and placed a comforting hand on the small of his back. “I care about you, Doc. I may get a bit carried away when you're begging me... seeing what you're like, I'm much more worried about hurting you than the other way around. Maybe we should have a safe word? Especially for this next part. Orgasm denial can be pretty intense.”
The Doctor stopped in his tracks. Orgasm denial. His stomach did a somersault at the words going through his head. “I... can take it,” The Doctor said, attempting to sound confident although he was in completely uncharted territory. They started to walk again.
“I'm sure you can, just humor me okay. Especially since this... mating season thing is all new to me as well,” Jack smiled and shook his head lightly. “Just promise you'll tell me if it's too much, alright? Just say, ya know, 'stop' or 'red light' or-”
“Captain-” The Doctor tried to interrupt.
“No, that's probably not a great pick. You'll be saying that one a lot,” Jack winked and chuckled as they made their way together through the TARDIS hallways.
