Identify kerfuffle in four parts:
Part One:
Bruce didn’t mean for it to happen like this. Not that he’d thought about it many times before — don’t listen to his kids; they exaggerate how much Bruce overthinks things. But if he’d been asked and he had felt the out of character urge to share, he would have said that it would probably happen after a particularly difficult battle, with one or two close brushes with death, emotions running high, adrenaline crashing through their bodies — do Kryptonians have adrenaline? He mentally adds it to the list of biological questions he can now probably ask without it being too weird — resulting in a desperate crushing of lips in a dark corner of the watchtower.
Not this. Not Bruce Wayne “tripping” into Superman’s arms after a textbook recovery of “Brucie” after his 501st kidnapping. Clark’s “Mr Wayne, we have to stop meeting like this,” a line he uses all the time, in and out of the suits with Mr Wayne swapped out to Batman and, on rare occasions B, the same nickname his sons use causing a traitorous skip of his heart every single time.
And Bruce is just so happy to see Clark; it hadn't been a hardship per say being kidnapped this time, unless you count being talked to death by the Riddler for the last six hours, which Bruce is pretty sure he'd take being tortured over having to endure that again so he was pretty damn happy when Clark had come crashing through the warehouse roof to rescue him.
Bruce had fallen into Clark's rather sculptured arms and he had said that stupid cheesy line and Bruce just hadn't been able to stop himself from leaning up and planting a kiss on those plush lips. Which upon parting in surprise Bruce deepened the kiss to probably a level of inappropriate for public, not because of scandalous reasons, that would in fact work for Bruce's alter ego, but because even though it was a first kiss, it didn't feel like it and to an astute onlooker might seem too familiar for rescuer and rescuee. The way their tongues danced and breath synced spoke to the years they'd spent working alongside each other. How well they knew the other move was obvious in the coordinated waist grab and fingers tangling in the curls at the back of Clark's neck, anticipating the next step exactly how they would during a battle; with unspoken agreement, a slight tensing of muscle, the quite exhale of breath. When Bruce finally pulled back, Clark looked dazed, a similar to the look "Brucie" usually displayed when wanting to come across to people as dimwitted.
Bruce extracted himself from Clark's grip, straightened his crumpled suit and with a wink said, "A pleasure as always, Superman," Before disappearing into the growing crowd of Gothemites.
Little did Bruce know, Clark used that line on most people he'd saved at least three times. And while he took special pleasure on using it on Batman because the man's usual brooding exterior would sometimes crack just a little to let out a huff of annoyance with the smallest hint of amusement and Clark coveted that.
Clark had certainly not expected Bruce Wayne to take it as sign of familiarity enough to kiss him, but what a kiss it had been, Mr Wayne was known for his …uh …dalliances and they had resulted in a man who knew how to kiss. Clark had forgotten where he was and almost his own name until Bruce had smugly winked and called him Superman. Right, people were watching, expecting the usual hero schtick. He let out a laugh, aiming for golly but defiantly leaned a bit too hysterical, "Not an ever day thank you, that's for sure."
When none of the gathered people laughed, Clark awkwardly cleared his throat, "Right, well I should get going, people to save an all." And with that Clark leaped into the sky and if he almost flew into a plane because he was so distracted thinking about the kiss that was between him, the pilots and the 300 and something passengers that got a fright.
