Kyungsoo shivers and laughs and untucks Jongin's dress shirt from the waistband of his pants, sliding his hands up the flat plane of Jongin's back. "Happy debut anniversary to you, too," he replies, mouthing a kiss against Jongin's throat, just above where his collar is. "We have probably five minutes before the managers start looking for us."

There's nothing graceful about the way Jongin shoves Kyungsoo back into the bathroom stall, or about they way they kiss, all slick tongues and lips as their hands work into each others' pants. But Kyungsoo has never really needed elegance as long as he has Jongin, so he's content to be jerked off rough and brutal, muffling gasps and sighs into Jongin's mouth as he tries his best to return the favor.

"Holy shit," Jongin murmurs, then sucks on Kyungsoo's lower lip, teeth dragging against it. "You make me so easy—"

And it's true, Jongin is easy for Kyungsoo. Or maybe it's just that they've been doing this for so long that Kyungsoo knows exactly how to twist his wrist, how to flick his fingers to have Jongin trembling against him, knees shaking as he spills into Kyungso's cupped hand.

Jongin falls still after that, and Kyungsoo whines impatiently, jerking his hips up into Jongin's loose fist. It takes a second for the message to get through, but it does, and Jongin laughs and fists Kyungsoo and strokes, once, twice, three times before Kyungsoo bites down on his own tongue and comes so hard he sees stars.

They clean each other up with toilet paper, Jongin giggling a little immaturely as they flush it down the pipes. It's not like it's the first time, but Kyungsoo doesn't say anything, because he's happy and sated and content with his life. "Does this mean you're going to stop trying to fondle me while I eat?" he asks as they wash their hands, shooting a sidelong glance over at Jongin at the next sink.

Jongin smiles, all teeth and innocence that Kyungsoo doesn't believe for a second. "No promises."
