Pandora here with today's prompt: endurance! Yuri is 19 and JJ is 22.
In Yuri and JJ's languages (native or otherwise) the words 'I bet' are the two most dangerous – as much to other people as themselves. Like red rags to bulls, the words carry challenge and goad them into all manner of situations, many of them bad or at least ill-advised. They should both know better than to rise to it, but the words come so easily.
"You're insatiable," laughs JJ as Yuri's lips explore his neck yet again. They're still tangled together in their blankets and the air smells like sweat and cum. "Let me catch my breath!"
Yuri bites JJ's earlobe gently and shrugs. "I like fucking you."
JJ laughs again. "I gathered after the last two times today." A thought comes to him and he voices it unthinkingly. "I bet you couldn't go cold turkey very long."
Yuri scoffs. "I could go longer than you."
"You think?" There's a grin in JJ's voice that Yuri comes face to face with when he sits up.
"Obviously," he says, chin jutting stubbornly. "You'd be begging me for it before I even noticed the loss."
"I doubt that," smirks JJ. Something glints in his eye and Yuri raises an eyebrow.
"Let's fucking do this then," he says, smirking back.
JJ nods and they settle back into the pillows. A moment of silence passes before they glance at each other.
"Starting tomorrow though, right?"
"Of course."
Otabek sighs. When he suggested to the others that they all come to the rink for the evening, just to mess around and relax during the competition period, he didn't expect front row tickets to the 'who can be more of a little shit' contest between Yuri and JJ. He knows about the wager (Yuri told him, even after he'd said he didn't want to know) and he's fairly certain Mila does now too, as well as JJ's friend Aluin. This suspicion is confirmed when Aluin gives up and bellows what they're all thinking to the pair across the ice.
"Oh my god just fuck already!" The words echo around the rink and JJ and Yuri stop in their attempts to provoke one another to look at him. "Please! You're making everyone miserable!"
"And weirdly aroused!" calls Mila. When everyone stares at her silently she giggles. "Just kidding!"
"Yeah Yuri, give it up," smirks JJ. Yuri glowers at him.
"No way!" he growls. "Stop embarrassing yourself and admit you want to fuck me!"
"Okay, nope," says Otabek. "I don't want to hear any more."
He skates off the ice, Mila and Aluin following, and eventually Yuri and JJ are the only ones left in the rink.
Yuri sighs, the tension barely leaving him. Even he's shocked at their sheer pigheadedness: it's been weeks of no sex and he's just about ready to climb the walls. Every look JJ gives him, every brush of his fingers on Yuri's skin, every chaste kiss makes Yuri's spine tingle. He's come close to breaking twice already.
He looks over and sees a face that reflects everything he's feeling right back. Wordlessly they reach for one another and their lips crash together, pressed so close not even a breath could pass between them.
"Fuck the bet," Yuri murmurs when they resurface for air, and JJ nods before diving in for another heated kiss. Yuri grabs the zip of JJ's jacket and pulls it down. JJ breaks the kiss again.
"Really?" he asks breathlessly. "Here?"
"If not now I might go crazy." Despite himself and the flush in his cheeks, Yuri smirks. "Why, you scared?"
JJ laughs wolfishly and grabs Yuri's backside. "You wish."
