Raising a hand, Code knocked on the apartment door in front of her. The lizard was still wearing her button-up shirt and slacks, having come over after work without going home first, and she stretched her arms over her head as she waited, a laptop bag slung over one shoulder.

Soon enough she heard the door being unlocked, and it began to swing open. "Hi there-" Code began, but she trailed off and her gaze drifted downwards rapidly; Tsunami had answered the door naked, and the lizard/dragon hybrid in front of her was quite a sight to see. His deep blue chest and all the well-built muscles on the front of him were bared, while his shoulders, back and the top half of his head were a lighter color of blue, with turquoise lines running through them from his cybernetics. Even more obviously synthetic were his arms, legs and tail, which had been replaced with enhanced cybernetic versions, a combination of light gray metal plates, dark gray undersides, and bright blue lines running over them.

But what lay between his legs was all-natural, a deep blue uncut cock draped flaccidly over his balls, which rested against his inner thighs, attracting Code's gaze quite readily. Seeing where she was looking, Tsunami's lips curled into a grin, his four eyes gazing at her, one hand reaching up to one of the many horns on the back of his head and neck and holding it as he struck a pose. "See something you like?" he teased.

She tore her gaze away from his loins and smirked at him, her long tail swaying behind her. "And what would you have done if it was someone else at your door?" she asked playfully.

"Made it a threesome?" he answered jokingly, stepping back and holding the door open for her. Chuckling, she entered and left her laptop bag by the front door, turning to face her host once he closed the door to his apartment and locked it again.

"Well, I guess you'll have to be content with having me all to yourself," she said playfully, flicking her forked tongue out at him. "I'm not going anywhere else tonight. What've you got planned?"

Leaning on the wall, Tsunami used his free arm to make a finger-gun at her. "Pizza got here just before you did, I've got a movie queued up, there's some gallon jugs of water on the coffee table, and a bottle of lube on the shelf under it."

"Now that," she replied with a swish of her hips, "sounds like my kind of evening. You're still on for that contest you wanted, right?"

His grin only widened. "Sure am, are you?"

"I went to the bathroom right before leaving work," she answered. "So let's see who can hold more, shall we?"

--------------------

Shortly thereafter, Code and Tsunami were sitting naked on his sofa watching the movie, Code's clothing left draped over her laptop bag. In addition to the promised pizza, Tsunami had also provided them with small ceramic cups, and each time there was a lull in the movie, he poured some water into each for them to drink together.

At first, it was nothing more than a refreshing, if bland drink to go with their dinner, the two naked reptiles enjoying the movie. But as it began to reach its climax, Code was vaguely aware of the beginning of a need to empty her bladder, one that she firmly ignored; there was no way she was going to give up this early.

Between scenes, Tsunami poured out another cup of water for each of them. She raised hers as he did the same, and she kept her eyes on the screen while gently clinking her cup against his own.

He chuckled quietly, bringing the cup to his lips and knocking it back in two gulps, hearing Code doing the same beside him, before they set the cups down on their coasters. Much like her, he only just barely felt the need to piss, but he'd be able to hold it for a while yet. He sat back to watch the end of the movie with her, staying quiet as it wrapped up, but once the credits started rolling he leaned forward to open up another jug of water.

"Good movie," she told him offhandedly as she watched him fill the cups again. "I can see why you wanted to get it out of the way early though, with that big scene at the waterfall."

He chuckled, setting down the jug and raising his cup. They both chugged the contents once more, and he gave an exaggerated gasp of satisfaction as he set his cup back down.

"Feeling it yet?" she teased, looking over at him with a grin.

"Eh, only a little," he said, playing it off. Their steady intake of water certainly wasn't helping, but he did his best to act like it was no big deal.

"Oh yeah?" she replied, shaking her cup, "Then maybe you should pour us another one and get this moving along."

He raised an eyebrow, tilting his head and giving her a questioning look with both eyes on the side of his head closer to her. However, he did oblige, picking the jug back up and pouring out another round of water for them both, the two lizards raising their cups to gulp it down.

Tsunami returned his cup to the coaster, grabbing the remote and flicking through TV channels to find something to have in the background. "I'm going to win, you know," he said confidently.

"Mm, don't be so sure about that," Code taunted, leaning to the side and resting on the armrest of his sofa, her tail draping against the front of it and tapping on the cushions idly. "I've had to sit through many gauntlets of meetings in my time."

"We'll see, we'll see," he replied, doing his best to psych her out. Finding something to watch, he set the remote down and leaned back in the chair.

A few minutes passed, and Tsunami noticed he was subconsciously shifting back and forth in his seat as the pressure in his bladder slowly grew. Glancing with all four eyes to his side, he couldn't see any similar motion from Code – but he did notice that her thighs were pressed very closely together, and he smirked to himself. It was still close after all.

Leaning forward, he poured out more water for both of them. She sat up to reach for it, and he barely noticed her squirm in momentary discomfort as she did. She looked right at him as they both drank, as if she were making sure that he was drinking too, and she kept her gaze locked on him as they set the cups back down.

"I know, I'm a sight for sore eyes," he teased playfully, spreading out his arms and leaning back against the sofa, using the motion to disguise the fact that he was shifting his hips back and forth. "You can touch me if you want."

"As tempting as it is to get my hands on your sexy blue body," she said flirtatiously, "I wouldn't want to make it easier for you to stay dry, would I?"

"Heh, fair, I don't want you to think I have an unfair advantage when I beat you," he replied with a grin, putting both hands behind his head.

She rolled her eyes with a smirk on her face, though he saw her tense briefly and press her legs more tightly to one another for a moment. "We'll see, we'll see."

Tsunami let a few more minutes pass before he poured out more water – even though he couldn't hide his shifting in place, she was squirming in her seat as well. To her credit, though, she took the water without complaint, drinking it along with him but keeping her legs pressed together the whole time. His body was reminding him again and again that his bladder was getting full, but he stoically ignored it, taking deep breaths and trying to concentrate on the TV.

But he couldn't. The words from the TV reached him, but he didn't register them as anything more than noise as he focused on holding his bladder every time he felt a pang in his abdomen. Beside him, Code had her legs crossed, and she was starting to rock back and forth as she stared straight ahead, in a similar state of need.

He was pretty sure she was in a worse state than him... pretty sure, at least. Regardless, after some time he eventually reached out to pour more water, though he did so slowly, trying not to lean too far forward lest he place any additional pressure on his aching bladder.

Code panted softly as she took the cup of water. "It's on now, isn't it?" she asked rhetorically; they were both squirming in their seats, so the answer to the question was obvious.

"Yeah," he answered simply, raising the cup and drinking, taking deep breaths as he set the cup back down. "I'm getting pretty full over here. You must really be bursting."

"Not quite yet," she told him, shaking her head, "But I'm getting there. Don't think you're getting out of it that easily."

"Heh." He grinned at her, wiggling in his seat. A few minutes later he noticed her put one hand between her legs to hold herself tightly, but he couldn't taunt her about it; his bladder was full to the brim and constantly aching, begging him for a release. All he could do was follow her lead and put a hand between his legs as well, holding himself firmly.

Neither of them paid any attention to the TV as they both focused on keeping their piss inside of themselves. Code shifted and wriggled, keeping one hand between her legs and pressing firmly there, while Tsunami bit his lip and clenched his muscles every time his bladder protested. She was holding out better than he had expected.

"Mmh," she eventually groaned in discomfort, putting a second hand between her legs.

"You can forfeit any time..." he murmured to her.

"Nuh-uh," she said with a determined shake of her head. "You're going down."

He did his best to remain nonchalant, but with a pang of discomfort coming from behind his abs every couple seconds, it was difficult. "I thought you wanted me to lift you up if you won, not go down on you."

She gave a chuckle and stuck her forked tongue out at him. "That's not what I meant, and you know it. Just you wait, I..." she cut herself off with a gasp and a groan, bringing her second hand between her legs.

"I am waiting," he replied, biting his lip and closing his eyes for a moment. "Don't worry about the sofa. It's easy to clean."

"You're the one who-" she began, but grunted again and squirmed in place, swinging her legs a bit as she shifted back and forth more; had she been standing, there was no doubt she would have been hopping from foot to foot.

Tsunami took deep breaths, trying to calm himself and take his mind off his own desperation. He was rapidly approaching his limit, and all he could hope for was that her bladder would give in before his did.

Leaning forward slowly, he picked up the water jug, and Code watched with apprehension as she slowly refilled their cups once more. "Another?" he offered.

She hesitated, using both hands to hold herself, but eventually reached out and picked up her cup. "You're on," she told him, her voice slightly shaky.

They both drank, albeit slowly, taking several gulps to drain the cups. She put hers down and abruptly returned her hand to between her legs with the first, taking deep breaths as she rocked back and forth, her eyes closing tightly. Tsunami did his best to watch her, but his over-full bladder was making it hard for him to focus.

Somehow, they both managed to last another couple of minutes, though they felt much longer than that with all the squirming, clenching, and bouncing in their seats. Neither spoke, both just trying to focus on outlasting the other, listening to the grunts and groans of the other just in case one of them was enough to signal the end of their contest.

"...fuck," Code gasped under her breath, pressing her legs more closely together. Tsunami bit his lip again; was this it? He wasn't sure if he could hold out much longer, and pressed the heel of his hand against his lower belly just above the base of his dick. One of them was about to burst, he was sure. He could feel his piss trying to get out, but he just needed to hold on a bit longer...!

"Fuck," Code muttered again, taking heavy breaths. "Ah... oh fuck..." She was fighting it, but it was a losing battle. She shuddered in place on the sofa, her legs pressed tightly together around her hands. "Nnh..." He could barely focus enough to watch her, as she went still, her teeth gritting. He just had to hold on a little bit longer, but his bladder was practically screaming at him...!

But with a sudden cry, Code shuddered once more, and then un-tensed as she let out a groan, both of relief and defeat, her shoulders slumping and her head tilting forward. Groaning long and low, he saw her take her hands away, both of them dripping with nearly-clear fluid, and he heard the hissing sound of her piss as it gushed out from her urethra, pattering on the sofa cushion under her. A big dark stain was spreading out from under her thighs already as she soaked the cushion, her half-opened eyes rolled upwards as she basked in the relief from her desperate release as her strained bladder finally emptied itself.

It was too much for him – seeing and hearing her relieving herself prevented him from holding on any more, despite his best efforts. As he felt the dam burst and a groan escaped his throat, he reached down with his right hand and pinched the excess forescales around his cocktip shut, trying to hold on just a bit longer, even though he had already won. Hot piss blasted out from his cocktip and into the inside of his forescales, making them balloon outward to contain it as he kept his fingers pinching it shut. Despite his best efforts to clench his muscles and stop the flow, he couldn't do anything more than weaken it, and the pressure within his forescales soon became too great. Some of his piss escaped around the edges of his fingers, and he let go of it, a big gush of nearly-clear urine erupting from his cock and splashing onto the rug in front of him before subsiding to a thick, lazy stream that poured from the forescale-covered tip of his shaft.

"Damn..." Code murmured, her eyes watching his cock as he leaned back and slouched in his seat, pissing all over the rug, "If only I'd held out a bit longer, I could have won."

"You were good..." he murmured, resting his head on the back of the sofa to enjoy his release, "...but not as good as me."

Both of them breathed deeply as they recovered and allowed their bladders to empty, Code drenching the cushion further and further. Meanwhile, Tsunami's piss began to splash the saturated rug, a puddle and a layer of foam forming on the top of it as the excess urine spread out through the fibers slower than he added to it. When she was nearly done, she lifted up her hips, and he watched the last drops of her watered-down piss fall onto the cushion, the lizard clenching her muscles and forcing out the last couple of squirts. Tsunami clenched as well once his stream started to wane, making his dick twitch and spray a different part of the rug for a brief moment, the final stream of droplets at the end dripping straight down from his forescales.

They both panted briefly, and Code eventually flashed him a grin. "Well, you won, do you want your reward now?" she offered.

His grin was just as broad as he stuck his hips out a bit further, spreading his legs. "Of course I do," he answered.

She admired his body and particularly his endowment, flicking her tongue over her lips. Leaning over, she reached out and slipped a hand underneath his sack, rolling his balls around in her palm. "Mm, a pity I didn't win, I wanted to feel these bad boys slapping against me," she told him, swishing her tail above her rump.

"You can come back any time," he teased, "but you can still show 'em some love now, yeah?" Raising his arms, he put his hands behind the back of his head and kept still – the loser of the bet was supposed to do all the work, after all, and he fully intended to lie back and enjoy what was coming.

"True, true," she murmured, bending over further at the hips. She used her free hand to lift his cock out of the way as she kissed and licked at his big blue balls, rubbing them from underneath. Feeling his length throbbing, thickening and stiffening in her grasp as she tended to him, she closed her fingers around his shaft and began to stroke slowly, helping to get him worked up as she smooched at his sack and flicked her tongue out against it.

Tsunami closed all four eyes and enjoyed the attention she gave to get him aroused. As he hardened up fully, he could feel her grip tighten, pulling his forescales down and sliding them back up, briefly exposing the cockhead that was still glistening with his own urine. When she slipped her hand out from under his orbs, he opened both eyes on one side of his head and looked down, watching as she gave him a smooch at the underside of the base of his cock before slipping away.

But she wasn't going far – just enough to grab the bottle of lubricant that he had stashed under the coffee table. He watched with a wide grin as she opened the cap and started pouring it generously onto his cock with one hand, the other stroking him and pulling his forescales back down to fully expose the pink glans underneath, getting it slicked up with the clear lube. Closing the cap on the bottle with one finger, she set the bottle aside and continued to slick him up, slathering the lube thickly across his entire length.

Once he was ready, she stood before him and turned around, flaunting her ass towards him, baring her slit and tailhole as she wiggled her hips. The undersides of her legs were still damp with her piss from before, and her pussy was wet with her own juices, but she didn't ride him right away. Lifting her tail high, she took her lube-covered hand and reached back, teasing him further by pressing a slick finger up against her rear hole, sliding it around her rim before pressing inside and teasing the digit around her rim right in front of him, slicking her anal opening in the process.

"Looking good," he growled lustily, his arms spread out across the back of the sofa as he kept his hips pushed out, his slicked cock standing upright and bobbing a little. He watched as she pulled her finger free, looking at him over her shoulder as she lowered her hips, reaching between her legs with her slicked hand to grab his cock and line it up against her back door.

"Here we go," she told him before starting to sink down further, starting to take his tip into her ass. The forescales bunched up against her sphincter, and once his tip started to penetrate, the tightness of her hole rolled back the forescales and caused his cockhead to slide into her tight tunnels first. Both of them groaned out, Code's toes curling against the rug below, her dry hand reaching out and grabbing the armrest of the sofa for support as she continued to lower her hips, gradually taking that lube-covered cock into her ass.

Halfway down, she paused and raised her hips up a little, then lowered them again, taking more of his length into her tight tunnels. Sucking in a breath when she lifted her hips, she let it out as a groan on the way back down, keeping up the pace, while he did his best to keep still, letting out moans as well as he felt her rear tunnels squeezing around his cock. Soon she hilted on him, and ground her ass down into his lap, her wet pussylips dripping nectar onto his balls as the whole length of his dick throbbed within her.

"You're so tight! I love it," he mumbled to her, resisting the urge to buck his hips upwards.

"And you're pretty big," she said, returning the compliment, "I'm going to enjoy this ride."

She raised her hips again, but faster this time as she started to bounce in his lap. Her rump slapped against his lap as she took him to the hilt each time, raising her rump and falling back down on him, taking his cock into the depths of her ass again and again. Her moans mixed with his, and she kept her tail raised high so he could watch her rump swallow up his shaft repeatedly, his preseed leaking into her depths as she kept bouncing and making his meat keep stretching out her anal passages.

Leaning back and groaning, Tsunami's hands gripped the back cushion of the sofa as she kept riding, sometimes with smaller thrusts and sometimes with bigger ones. Soon, though, she changed her pace, and began raising her hips up further, sliding most of his cock back out from her tailhole, then lowering her hips again back down to the hilt, his slicked blue dick disappearing into her ass once again. The tightness of her walls around his sensitive flesh made him shiver in pleasure, his forescales getting rolled halfway back over his tip when she raised up, and then pulled back down when she descended.

More of her pussy juices leaked from her slit, dripping onto his sack and the sofa cushion under him. She was panting for breath, partly from exertion and partly from arousal and pleasure, her forked tongue hanging out of her mouth. Behind her, Tsunami squirmed a little in his seat as she pleasured him with her ass, his hands clenching and gripping the sofa, while he copiously leaked precum inside of her. She changed her pace again, drawing her hips up slowly and then slamming them back down, his cock getting engulfed by her ass as if he were thrusting into her.

"I won't last much longer if you keep this up," he grunted, finding it hard to keep his eyes open as he tried to watch Code's ass descending on his shaft over and over.

Hearing his warning, she slowed down for just a moment, catching her breath, grinding into his lap each time she hilted on him – but soon she picked up the pace to a rapid bouncing again, moaning out alongside him as she went for the finish. His length pulsed within her, and juices dripped from her slit, both of them approaching the edge.

It was Tsunami who finished first this time, shuddering underneath her and letting out a groan of orgasmic pleasure as he couldn't help but buck his hips upwards just once. Code kept riding him as his cock erupted within her ass, her moans getting higher pitched as she pushed herself over the edge and joined him in climax, hilting on him and all but collapsing into his lap as she stayed there. Her ass tightened and clenched around his shaft as it fired thick ropes of cum into her, her pussy walls convulsing around nothing and squirting juices liberally into his lap as she squirmed against him and he trembled under her.

He brought his arms forward and wrapped them around her, holding her tightly to his front as he filled her ass with hot, thick seed, the pair both giving loud moans in between pants and gasps for breath. When they came down from their peaks, they were both left panting, savoring their afterglows, Code additionally basking in the warmth that Tsunami had pumped into her.

After catching his breath, Tsunami leaned in and nosed against Code's neck lightly. "Thanks," he murmured. "Let me know when you're good... we need to go take a hot shower together."

She nodded between breaths, and several seconds later she slowly pulled herself off of him, his cock sliding out of her with a wet noise, the lizard clenching her ass to ensure his load didn't spill out of her.

Tsunami exhaled as he slowly got to his feet, guiding her towards his bathroom. "So," he asked her as they walked, "how about a rematch some time?"
