Chapter Text
“Stand in the containment field.”
The Doctor gave her a moment to move before starting on the locks. Only a few days had passed since the start of her sentence, and he was still in the process of renovating the Vault. It had been made to house a corpse, after all, not a living person. Even if Missy was his prisoner, she still deserved the bare necessities.
The doors opened, and the Doctor stepped inside. Missy leaned against one of the containment field’s support beams, arms crossed and one leg bouncing as she eyed him.
“One food machine,” he said as he dragged it in, “Happy now?”
“No, actually,” she muttered.
“Look, Missy, this isn’t ideal for me either, but-”
“Doctor, what are the basic rooms in any home?”
He looked up at her. “What?”
“Name all the rooms you’d find in a habitable living space.”
Brow furrowed, the Doctor thought. “Uh… kitchen, bedroom, bath-”
Suddenly, it hit him. Taking notice of her bouncing leg and stiff posture, he averted his gaze.
“Oh.”
“Yeah.”
“And you have to-”
“Yes.” She sounded frustrated, which the Doctor could hardly fault her for.
“How badly?” he asked.
“Badly.”
“Ok…” He rubbed the back of his neck, still avoiding eye contact. “Can you hold it until I can… configure something?”
“If I can’t, you’ll be cleaning it.”
“… Yeah, that’s fair.” He headed for the doors, briefly glancing back without looking directly at her. “I’ll, uh… I’ll try to be quick.”
Hurrying out, he locked the doors behind him, speed-walking all the way back to his TARDIS. He felt like an idiot, overlooking something so vital.
Still, it should be an easy fix. If he made some adjustments to the dimensional circuit, expanding the Vault just enough to add one small room, he should have a bathroom ready for her in… two hours. Oh dear.
“She’s held it for at least three days, she should be fine a couple more hours,” he mumbled to himself as he gathered the tools he needed.
Would she, though? She looked pretty desperate, didn’t even give a definitive yes or no when asked if she could hold it. Either way, she had to be incredibly uncomfortable. Fifty-six to sixty hours was about as long as a Time Lord could comfortably hold their urine, and Missy was well over seventy-two.
The Doctor felt bad, he really did. If she had an accident, it would serve him right cleaning it up. All those hours Missy must have spent squirming, the amount of willpower it must have taken to remain as composed as she was when he was down there; it must have been torture. The thought of her struggling to stay in control, fighting as hard as she could to keep all that urine contained… turned him on, quite a lot judging from the stiffness in his trousers.
This was… new. He’d been around long enough to know that there were people out there who got off to that sort of thing, but it was never something that he’d gotten off to before. Was he attracted to Missy? The two of them have towed the line between enemies and lovers for centuries, so yes, of course he was. Had he ever been turned on by the thought of his oldest friend wetting themself? No! In any event, now was not the time to dwell on a new kink! Missy had to go, and unlike her, he didn’t enjoy making non-consenting parties suffer for his own amusement.
Think of something else, he thought to himself. Pears, gardening, Nardole…
His erection subsided immediately. Alright, well, that works.
~*~*~
The Vault doors opened, the Doctor doing his best not to look at Missy as he hurried inside.
“Took you long enough!” Missy huffed.
He couldn’t help it, he peeked up. She was trying hard to remain composed, but she was visibly squirming, clearly unable to hold it for much longer.
“I know, I’m sorry.” Averting his gaze, he hurried to the far right wall. Most of what he had to tinker with was on the other side of the door, but of course, the final adjustment had to be done inside the Vault. “Give me five minutes, ten at the most.”
Missy groaned, stepping out of the containment field as he pulled out his sonic. “Hurry it up, I have to go!”
“I’m moving as fast as I can,” he assured her, wishing more than anything that she wouldn’t stand so close.
“Well, move faster!” She crossed her legs, grunting as a hand flew to her crotch. “I swear, I could’ve gotten this done in half the time!”
The Doctor did his best to keep his head forward, but he could still see her squirming out of the corner of his eye. He could just picture it all coming out, her skirt becoming soaked by that uncontrollable stream. It would be a huge blow to her pride, wetting herself in his presence, but there would be nothing she could do. It would just keep coming out, the wet spot getting larger and larger, until-
Oh, crap. Now his pride was in jeopardy. Hoping Missy hadn’t noticed, he continued his work in haste, praying it would go away quickly. Unfortunately, Missy spotted it immediately.
“Seriously?” Despite her continued squirming, the smirk on her face was audible. “Do you have something in your pocket, or-”
The Doctor jumped back as he felt her squeeze his erection, his face turning a deep crimson as he swatted her hand away.
“It’s not like that!” he quickly said, his head turned in her direction, but eyes locked just past her.
“Oh, I think it is. So, this is what you’re into now? Seeing your friends about to wet themselves gets you off?”
“No!”
“Just me, then?”
“Missy!”
Biting her lip, the Time Lady let out an exaggerated moan, squirming even more as she grabbed her crotch with both hands.
“Oh, Doctor, you better hurry!” she pleaded in her usual overly dramatic, mocking tone, “I don’t think I can hold it!”
The Doctor groaned, turning away from her as he tried to ignore how painfully hard his cock was.
“Stop,” he half-heartedly mumbled. There was no way she would, nor would she ever let him live this down, but he still had to try.
“Please Doctor, please! I’m going to wet my panties!” She paused as she smirked. “Would you like that? Do you want me to wet my panties for you?”
Hitting his head against the wall, the Doctor groaned. “Missy-”
“Oh!” She hiked up her skirt, exposing her undergarment. “A little just came out!”
Against his better judgment, the Doctor glanced up. Sure enough, there was a small wet spot. Had she done that on purpose, or was she truly starting to lose control?
“Oh!” The wet spot grew, a few trickles running down her inner thighs. She crossed her legs tightly, stopping it before anymore could come out. “You better hurry, Doctor! I’m going to-!”
Suddenly, the Doctor lunged, pinning Missy against the wall. He pressed his lips roughly against hers, both of them moaning as his cock pressed against her thigh. Still gripping her skirt, Missy shuttered as her bladder spasmed, forcing another trickle into her knickers. With the Doctor gripping her arms, she couldn’t even move to grab herself.
The Doctor, however, slid his hand into her knickers, a genuine moan rising in Missy’s throat as he circled her clit. She’d heard that a full bladder could increase pleasure for some women, but hadn’t thought to try it herself. Now, she wished she’d done it ages ago.
“Doctor-!” she moaned, rolling her hips at his touch. Her bladder was panging worse than ever. Part of her wanted to tell him to get off her, to hurry and finish setting up the bathroom, but this felt too good.
Again pressing his lips against hers, the Doctor began to grind against her, getting some much needed friction to his cock. Knowing she was close – both to climax and wetting herself – his fingers picked up speed.
“I can’t hold it,” she moaned, her knees starting to tremble.
“Then I guess you will be wetting yourself for me,” the Doctor said in a low voice.
Missy’s hearts raced at his words. Looking up, she saw the darkness in his eyes, hungry and lustful, and sending burning arousal racing through her veins. As much as she reveled in being in control, it felt good to hand over the reins, just this once.
Screaming as she came, Missy rode the waves of ecstasy as the best orgasm of her life came crashing over her. No other high could possibly top this, nothing could be better than having the Doctor fingers pressed against her clit, her unbearably full bladder making everything so intense. A whole new world of pleasure just opened up, and she had no intention of turning it away.
As soon as her muscles relaxed, she felt it happen. Warm urine flooded her knickers, the relief of it being so incredible, she almost came again. Moaning as three days’ worth of urine finally came out, she went limp against the wall, the Doctor being the only thing keeping her upright.
“Oh, god.” Her eyes fluttered shut as she indulged in the feeling of her bladder emptying. Feeling the Doctor shutter and hearing him moan, her eyes opened, and she smirked. “Did you just…?”
The Doctor’s face turned red. “Yeah…”
Missy laughed. “I’m the one wetting myself, and you’re embarrassed about cumming in your pants?”
He snickered. “Well, when you put it like that…”
Biting her lip, Missy glanced down. Her stream was still going strong, soaking through her knickers, and thin trickles running down her thighs.
“You really like this?” she asked, sensually stroking her wet crotch.
The Doctor nodded. “Do you… feel better, at least?”
“Oh god, you have no idea.”
It took several minutes for it to all come out. Finally finished, Missy sighed in relief before letting her skirt fall back down.
“I’ll get a mop,” the Doctor grinned, looking down at the large, glistening puddle.
“Better finish with the bathroom upgrade first, dear,” Missy advised, a grin of her own on her face, “I think we both could use a wash.”
