The last thing the Doctor expected to see when he opened the Tardis doors was himself. Not just any version of himself but the pretty blonde in his stupid beige suit who’d gone off and sacrificed his sorry self and caused that horrible regeneration whose effects he was still feeling; Right then, he was looking up a bit dazed at the sky, with his mouth ever so slightly open.
“Where did we end up this time?” the blonde man said.
“Epsilon 8. The edge of the Andromeda Galaxy,” Six called out nonchalantly.
The fifth doctor spun around to see the other man leaning against a blue police box. He looked back behind him to check that his Tardis is where he left it –it is, with its door still open, and his companions most likely still asleep inside– then back at the other Tardis.
He looked Six up and down, and slowly forced out, “you’re me.”
“You don’t have to sound so disappointed.”
“Your… outfit is a lot louder than I’d ever wear.”
“We still have the same collar at least,” Six quipped back.
“At least,” Five sighed back, with a tinge of what Six annoyedly registered as dread, or something close.
“And of course, you’d be the one to hate yourself,” Six muttered loudly.
“What’s that supposed to mean?”
Six kept his mouth shut.
“So why did you get sent here?” Five tried again.
“Sent here?”
“Well if the two of us are here, that means something really bad is going on doesn’t it?”
“Why would you think that?”
“Because there’s two of the same person in the same place,” Five said, frustrated, “the laws of time! How could you not think of that? Did something happen to me?”
Six scowled deeply. Something did happen in fact, and in his mind, it was his Fifth regeneration’s fault. Not that he’d sacrifice Peri if he could go back and change things. He’d never consider that, and he’d never let it happen. He still wasn’t sure if he’d forgiven himself for strangling Peri, even if Peri acted like she’d gotten over it. He always had the sense she liked the bloody bastard in front of him better than she liked him. He turned back up to glare at Five.
“With as many of us as there are traveling around all the time, we’re bound to just run into each other sometimes, okay, little fivey,” he sneered.
It was the Sixth Doctor’s first time seeing his past self since his regeneration, which wasn’t much of a surprise given how recent his regeneration was and how dangerous it is to cross your own timeline. He was fully aware of that but didn’t want to acknowledge it simply out of spite for his past self.
He knew it was irrational, but he couldn’t get over the feeling boiling inside of himself as he looked at the cheerful blonde figure (all though less cheerful now). Even if Five hadn’t done it yet, the Sixth Doctor needed a release from that anger he felt towards himself for how unstable he’s been since that disarray of a regeneration and all that he’s put Peri through because of it. And what better scapegoat than the man who’d done it (or who was to do it, technically).
“If it’s just a mistake that we’re both here, I’ll be going. I wasn’t actually trying to end up here in the first place,” Five said.
Courteously, he added, “I look forward to being you.”
Something inside of Six snapped at that line and the stupid politeness Five kept even when talking to his own self, and he lunged the length between him and grabbed Five’s collar. Shock splayed across his face, and his lips parted slightly in fear.
Six pulled the man behind him, towards his own Tardis. Five tripped over his white cricket shoes following him, and Six wrapped his stronger arms around Five’s body, picking up the only slightly shorter version of himself, and hoisted him partly over his shoulder. Five barely puts up a fight, but still squirms while pushing at Six’s arms, telling him to unhand him, to put him down, to let him get back to his Tardis.
Six had made up his mind.
Once in the Tardis, Six put him down against the console, taking the pretty man’s suspenders into one hand and wrapping his other around Five’s small ass, gripping it painfully tight.
“I’m going to rewrite our timeline just to fuck you,” Six whispered.
Five whimpered in response, wriggling in the bigger man’s arms, trying to protest once more, but not being able to form the right words. He managed to splutter out a mix of, ‘that's wrong’ and ‘no, it’s not just wrong, it’s a crime’ and ‘the timelords’ and yet another, ‘you shouldn’t be doing this’. Six didn’t budge.
Instead, he grabbed his predecessor's throat and pressed a finger over his mouth to silence him.
“Shut up pretty boy, you’re my slut now,” he growled, slamming Five into the console, and getting a yelp in response. He pushed his knee between the other Doctor’s thighs, rubbing it against Five’s dick.
Five knew he shouldn’t be liking this. He knew he shouldn’t be doing this. The timelords would punish him beyond imagination, and he’d be shunned forever if anyone got word that he’d crossed his own timeline just to fuck himself. Just to get fucked. But as the other man shucked off his jacket and leaned towards him in his outlandishly multicolored vest (and he’d noticed the strength and muscle hidden behind it) he’d felt so small, in a way he liked more than he could admit. He couldn’t help but feel his dick twitch, betraying him. He could only hope the other Doctor hadn’t felt it.
But he had. The glint in Six’s eyes confirmed it, and Five felt his face flush as he turned away.
“You’re heating up so much you could probably cook that celery of yours with your own body heat,” Six laughed in his ear.
“It’s out of embarrassment,” he protested, “this is humiliating, you hear me.”
“Oh I hear you,” Six whispered, his hot breath against Five’s ear, “I hear you panting. Your body wants me Fivey, why don’t you admit that.”
Five shook his head vigorously despite Six’s hand still close to his throat.
Then, suddenly, Six got up, leaving him grabbing at the edge of the console to stabilize himself. Five looked around in confusion, watching the Doctor head to the door. But this is Six’s Tardis. He can’t just leave him with the wrong Tardis.
Instead of leaving though, Six closed the latch on the Tardis door and turned back around with a smirk.
“We can’t have your Peri walking in on you like this can we?” He grinned wider, “Unless, of course, you want her to see you as the drooling whore who gets turned on by his own self using him.”
Five stayed stuck in place, speechless, willing himself to stay in control as he notices just how big the other Doctor is, in every way. He was a hulking mound as he walked over to him, looming over him with his broad shoulders. And his garish yellow striped pants. Oh god, Five thought as his eyes settled on them, unable to look away. The outline of Six’s dick, tucked up sideways in his pants, was one of the biggest he’d ever seen. He automatically imagined the weight of it in his hand, how it’d feel to hold that once he becomes Six, to slide his hand down that shaft as he gets off. He gasped as his dick responded to his thoughts instinctively.
Six jumped on that opportunity to grab his face once more, pressing his mouth hungrily against Five’s, tongue searching aggressively for passion. Five stayed stock still, his mind still repeating how he shouldn’t, he shouldn’t, he can’t be doing this.
“Don’t act as if you have a choice,” Six responded to his thoughts.
He doesn’t– not under the grip of his much stronger version. Every movement he made was pushed down by Six’s wandering hands. Six grasped his face in one hand, one finger pressing on each cheek, and one right under his jaw, pressing into his throat.
“You’re my slut, you hear me? My personal whore. And I’ll use you how I like.” Five looked up at him, eyes wide. “What do you say?”
“Please…” Five whispered.
“Please what ? You know what you have to say.”
“Please, sir, please use me.” Five whimpered out. Somehow, he just knows it’s the right word to use.
The right side of Six’s mouth twinged up, and he nodded slightly, “Good boy.”
Five knew he shouldn’t be happy to hear that. What right did his next self have to judge him like this? But sweet Rassilion did it feel good.
Six sent a sharp slap across his face, grinning at the shock that reappeared in Five’s eyes, like a betrayal. He didn’t want him getting too comfortable. He pushes the blonde man down from the console to his knees, one hand tightly on his shoulders, the other dealing with his trousers.
He didn’t even bother to pull his cock out of his underwear, shoving Five’s face against his crotch, and rubbing his nose against it. The sweat and the musk of Six overwhelmed Five, and he opened his mouth, tasting Six’s cock through his underwear.
Feeling the wetness of Five’s mouth, Six shoved him further against his body. “Suck it, baby.”
Five sucked at the fabric harder, wrapping his mouth around where the tip of Six’s cock lies. A part of his mind noticed Six calling him baby and wanted to react, but he was too lost in the sensation of everything to process it further. He had felt the thickness, felt the veins running down the sides, and ran his tongue over them.
“Good boy,” Six reaffirmed, and pulled him back with his hand wrapped into the blonde hair, taking his cock out of his underwear.
Gazing at Five’s pretty awestruck face from above, he slid the wet tip of his cock across Five’s already swollen pink lips. On a whim, he decided to slap his cock across Five’s face, just to see his reaction. The slight pain Six felt aroused him, but the precum on Five’s face and the knowledge that he was degrading that pretty man made him so much hornier. He shoved his cock into Five’s mouth, not holding back, slamming the man’s face all the way until his nose hits his body, his lips at the bottom of Six’s shaft. He felt Five choking, gasping for air as his throat fills up with Six’s massive cock, unable to breathe even through his nose. That was just as satisfying as the wet warm sensation of Five’s throat, Six thought.
Pumping Five’s face against his body, Six leaned over him slightly, whispering, “I know you want this, my slut, because I know you. You’re me. I can read every expression on your face because I’ve made them before.”
Five made noises, not in any language, around Six’s cock, his throat humming around it ever so slightly.
“Don’t bother protesting. I know even that fucked out empty expression you’re making now, from embarrassingly jerking off in my room a couple too many times. So sexually repressed right, pretty boy?” Six laughed, “But nothing as good as this.”
He pulled Five off of him to get a response.
“Yes sir,” Five said with wet eyes.
Six wiped away the tears under his eyes with a gentle thumb, then right after, grabbed his hair to drag him across the floor to a wall. Positioning the now complaint man against a wall, he started to fuck his face with even more vigor.
The sounds of Six’s moans filled the room. He was unashamedly vocal, something Five could never have done, would never have dared do, even in the confines of his own bedroom. It just added to the pleasure for Six, and while he’d do it even if he was alone, there’s a bit of him that enjoys putting on a show for Five, showing him how he can enjoy himself. He’d taken this man out of anger, but fucking him against the wall, having him on his knees, he felt oddly protective of him. He wanted to help the smaller man, even as he manhandled him. Six slammed his cock into Five’s throat over and over, feeling it contract around him every time Five got a shock, either from Six’s cock hitting the back of his throat or from the force driving his head into the wall.
“I’m close, oh,” Six shouted out, picking up pace, and moved quicker but smaller movements in Five’s mouth, keeping his cock mostly down Five’s throat the whole time. He shoved Five as far against him as he could, pinning him into his crotch, nose crushed in his pubic hairs. Five choked, trying to breathe as Six kept him there, cum shooting down his throat, filling it up. He hit Six’s leg, trying to get him to relent, but Six kept himself in him for a few seconds more, breathing heavily.
“Rasillion, you’re good,” Six whispered as he let Five get his breath finally. He let go of the man, who fell onto his hands, coughing.
Six noticed proudly, however, that his dick is still not completely soft. He was definitely in the mood for another round. He couldn’t let this end with them still fully clothed. He shoved the smaller man down, pressing his face and shoulders right into the floor, and pulled his hips up.
He struggled to pull off the suspends, but snapped them off on the third try, sending the elastic snapping away. The band slapped against Five’s back and he cried out. A smile crosses Six’s face as he thought of an idea. Pulling back the suspenders again, he lashed them against Five’s ass without warning. Five whimpered, looking even smaller as he pulled his arms around his reddening face. Six grew harder once again at the noise, and slapped Five’s ass with his free hand, hard.
“Oh what a toy you are, Fivey.”
He moved slowly suddenly, pulling down Five’s trousers with relish, licking his lips at the sight of Five’s pale skin. His pink hole twitched as Six ran a finger across it.
“I’ll do you the favor of warming you up, but I won’t do it pleasantly.”
Five nodded against the floor.
“What do you say?” Six demanded.
“Thank you, sir. Thank you for your mercy.”
“Good boy.” He shoved his two fingers into Five’s ass, causing him to jolt up against Six. With each pulse of Six’s fingers, Five shook up, his body tensing as though getting an electric shock.
“Oh my beautiful slut, you’re not getting it any easier,” Six whispered as he leaned over Five’s body, aligning his thick dick to the smaller man’s hole. Silently, he shoved his full length in, causing Five to scream out, his voice echoing around the room. As Six wrapped his hand around Five’s throat, he was hit with a wave of emotions again, part lust and part anger as he remembered the last time he had a hand around someone’s throat. He pounded against the smaller man’s ass. Five wriggled under him, moving to escape, begging him to let him go, begging him for release, in multiple ways. Six put his foot on Five’s head and felt his cock harden even more (which he thought was impossible until that point) at the feeling of power he got. He loved the thought of the humiliation Five was feeling, pinned down under his future self’s foot and getting pounded until all he could do was whimper and cry, dick leaking against the Tardis floor.
“Oh Fivey, you good, good slut. My personal sex toy and I can do whatever I want with you, can’t I?” Five nodded his head as best as he could with Six’s foot pressing down on him.
“Use your voice, whore,” Six said sharply.
“Yes, sir, anything, sir. Please use me to pleasure yourself sir.”
Six pulled out, flipping around the blonde man so he faced up. Six slapped Five across the face as Five looked up at him with teary eyes. “Of course I will.”
He rose onto his knees, and put Five’s feet onto his shoulders, pulling up his legs to get better access to the man’s ass. Five wondered how he could hold his weight so easily.
Oh Rassilon, he was pathetic, his dick leaking precum down his torso as he looked up at the looming figure of Six. He looked like a Greek statue, godly almost, with his mass of curly hair like a halo around him, Five thought. He shouldn’t be thinking this, he shouldn’t think a single good thought about this man, Five told himself, begging for forgiveness to whatever being might read his mind. As though he could tell Five was losing focus (perhaps he could) Six slapped him across the face again, leaving a burning sharp handprint on his cheek. Oh, that one was going to bruise. How could he explain that? Everyone’s going to know he’s a slut getting tossed around.
All too soon, Six’s breath picked up, and he all but slammed Five against his body, his body shaking as his cum filled Five. The blonde came to the sensation of being filled up, leaving white trails across his chest.
After his breath finally returned to normal, Six kissed the tip of Five’s nose, and whispered, “that wasn’t actually that bad right?”
After a pause, he added, “if you’re worrying about if this is right or wrong or ‘proper’, the time lords aren’t ever going to find out either way. They can’t see into the Tardis, and I’ll protect our secret. And, there’s nothing wrong with some sexual relief. You can stop shame wanking in your bedroom.”
Five nodded with wide eyes, and finally smiled up at him.
“Ok good. You can get yourself cleaned up in your own Tardis right?” Six asked, getting a nod in response from the man who was still lying on the floor below him.
Six got up, going to fetch their discarded clothes, and grabbed Five’s crumpled shirt, and wiped his dick off on it, then his balls, and rubbed the sweat shining on his torso and under his armpits off afterward, and threw it at Five, who looked unsure of what to do.
“Put it on,” Six commanded with a smirk. Five did what he said with his eyes wide open. He smelled Six’s sweat around him, and he could feel the traces of wet cum against his chest, right at the front of his shirt. How was he going to get back to his Tardis looking like this, he wondered.
As though he heard his thoughts, Six said, “Wear it proudly. Show the world you’re my whore.”
Five nodded, still ashamed at how turned on he was by this, by the smell of Six engulfing him.
“I’ll see you again?” Five asked.
“You’ll see me again.” Six responded.
