Work Text:
“2 minutes and 39 seconds!” Tim called out to Kon just after he stopped his stopwatch, writing down the results on his notepad.
They were in the Titan’s training gym, working on Kon’s super speed. Specifically, at the moment, they were testing how fast he could take on one of the holographic simulations.
“Bart’s still beating you with a time of 2 minutes and 1 second,” Tim told Kon when the supe sped over to where he was leant against one of the gym walls. Usually, it would be Bart helping train him, but the Allen’s had some family thing on.
“Fuck off, how?” Kon groaned, having barely matched Bart’s top speed before as well. Honestly, it makes sense given he was half human and not a full on speedster or kryptonian. However, Tim liked seeing his new boyfriend all hot and bothered too much anyway to remind him.
Besides, Kon wasn’t actually annoyed, just competitive. He didn’t need to be as fast as Bart when they usually literally worked together.
“Well, we have more time for you to try again,” Tim shrugged and Kon nodded determined, getting back into position. The next half hour was more of the same.
“2 minutes 31 seconds!”
“2 minutes 25 seconds!”
“2 minutes 16 seconds!”
And so on, until finally…
“Hm,” Tim hummed when he stopped the timer, just as Kon took a long swig of water beside him. “That one was actually 2 minutes and 43 seconds,” He noted verbally as well as wrote on his notepad.
“That’s bullshit,” Kon argued, putting down his water bottle on one of the many benches sprawled around on the sidelines. “Besides, I bet my super speed means I’m faster at other things,” He smirked.
“Like what?” Mumbled Tim absentmindedly, double checking what he had written. He pretended to be too distracted to notice as Kon stood in front of him and leant one hand against the wall behind him.
“Like getting you off,” Kon whispered into his ear. Tim swore he felt the blood rush to his face, as well as somewhere else in particular. He tried to hide his embarrassment though with a grin, meeting Kon’s gaze.
God, the amount of fantasies he had had about Kon’s powers were enough to get himself off for a whole lifetime. He just hadn’t worked up the courage yet to casually go ask if Kon could put them to unconventional - yet possibly amazing - use.
“Really? You think you can get me off faster than you can complete the simulation?” Tim rolled his eyes. He was fucking bluffing, of course. Kon could honestly probably get him off quicker with a well timed compliment and wink, let alone super powered sex. “Wanna bet?” He snarked.
“Oh I do, and when I win I get to fuck your then over sensitive ass into one of these gym benches,” Kon decided. “Maybe I could even fuck your face at the same time if I went fast enough,” He pondered out loud, earning a strangled gasp from Tim (although that was also because he gripped Tim’s dick at the same time through his gym shorts with the hand he wasn’t leaning on).
“Y-yeah, well when I win, you have to cockwarm me as I finish my case files. Without touching yourself,” Tim added, both of them knowing how long it could take him to do the detailed paperwork Batman required after every incident and patrol.
“Oh you’re on,” Kon agreed, flipping Tim around to face the wall, which reminded Tim they were actually floor to ceiling length mirrors. “Seriously, these shorts are deadly,” Kon groaned.
Tim felt his TTK glide up his arms and force him to drop his notepad and timer. Meanwhile, Kon pulled down the bird’s pants and underwear in one go.
“At this rate, I’m definitely going to win-“ Tim fell forward to brace himself with his hands against the mirror, failing in trying to hold back a moan. One of Kon’s hands had moved across his body to wrap around and pump his cock, at inhuman speed. “Shit, Kon!” Tim practically screamed, head falling forward to watch the near blur of his hand across his dick.
If he wasn't already hard, he definitely would be now. He could somehow feel all of it even when he could barely see any of it, the speed creating basically a vibrating sleeve over his dick. It was like Kon’s hand was forcing an orgasm out of him, and Tim knew he wasn’t even going as fast as he could.
“You’re stunning,” Kon groaned into the back of Tim’s neck, leaving a trail of hickeys wherever he could as he slowly kneeled down.
Tim moaned as Kon’s TTK molded into the sensation of hands, one carding through his hair whilst others also spread his ass cheeks. His hair was pulled back to force his head up, making eye contact with himself in the mirror.
Drool started to cascade from his open mouth as he panted, a deep blush on his face intensifying when he took himself in. He looked like he had been fucked for hours, not just started a bloody hand job.
“Already trembling and I haven’t even put anything in you yet,” Kon teased, licking a stripe up Tim’s ass and moving his hand faster. Shit.
The super’s tongue circled his hole, before sucking at his rim. Kon knew how to eat Tim out like he was a five course meal and put it to good use, delving his tongue into Tim’s now sensitive entrance without mercy.
That’s what did it. It was too much. Cum shot from Tim’s dick and splattered onto the mirror in front of him as he shouted Kon’s name. They were lucky they were the only ones at the Tower today.
Kon stopped the hand on Tim’s cock and held up the timer in his free one, which was now paused.
“1 minute and 9 seconds,” He mused whilst Tim’s entire being tried to catch up again with reality. “Honestly, you lasted longer than I expected. We should try this again another time. For now though, I win,”
With that, Kon picked Tim up and moved him over to lay on his front against a gym bench at super speed. It was one of those benches where it had a normal seating part, then the rest angled up to lean against.
Tim barely had time to come down from his first orgasm before Kon shoved two well lubed fingers inside him.
“W-wait- Don’t just-“ Tim tried to protest but was cut off by his own moan as Kon pushed his fingers right into his prostate. He hugged the angled bench that his chest was resting on tightly, the oversensitivity sending spikes of pain and pleasure through him.
In no time, Kon had prepped him and slid out his fingers, replacing it with the head of his cock.
“Safe word is Batman remember,” Was all the warning Tim got before Kon plunged into him and set a pace only speedsters could match. It was faster than his hand had been and almost felt like a vibrator drilling into the most sensitive parts of his insides.
It caused Kon’s entire body to vibrate against Tim. Which was fine enough, until one of his hands wormed its way around to simply cup Tim’s dick and balls.
“N-no- Too much- Konnn!” Tim mewled, his member starting to lengthen again through the overstimulation. Especially, since Kon also put a hand up his gym shirt and placed a finger right over one of his nipples. “St-stop- I’m gonna-“
It wasn’t long before Tim came for a second time, clenching unconsciously around Kon, who shortly followed and slowed down to a normal humane pace as he did so.
The two panted together, Kon finally coming to a halt inside Tim and moving his hands to rest on the wonder boy’s hips, leaning like a weighted blanket over Tim.
“That was amazing,” Kon managed to say and Tim chuckled.
“It… was,” He somehow breathed out, feeling like all his nerve endings were still on high alert whilst his head was just high off coming.
“Imagine how many more times we could go now when we have little time,” Kon realised out loud. His penis clearly also liked that idea as it started to fill out again in Tim. Fucking kryptonians having no refractory periods.
“Fine just- just don’t touch my dick,” Tim ground out. “Please,” He added.
“You’re the best,” Kon grinned, already starting to move again.
