i've read pretty much every batman-related post that @august-anon, @fickle-tiction, and @tickle-bugs have posted, so these may be incredibly derivative, but i'm hyper-fixating on batman/superbat so hard rn so take these
look, after all the training he has gone through to withstand just about anything, you would think that bruce wayne wouldn't be ticklish
and you'd be, like, half right...he's very good at turning it off and suppressing his reactions to it
but he still is ticklish—he is only human, after all
clark is one of the few people that bruce ever lets his guard down around enough for clark to discover this particular weakness
bruce is ticklish...well, pretty much everywhere
once you break his resolve enough to get him laughing, he's pretty much done for, like his whole nervous system reignites
his ears, neck, ribs, and hips are all extremely ticklish
he would never, ever admit it to anyone (except maybe clark, if he can get over the emotional constipation for one minute) but he sort of likes it. it's fun and it reminds him of his childhood and it makes him feel like clark really loves him, to want to touch him like that and make him laugh
clark is ticklish, too, but often ends up being the ler in his dynamic with bruce, simply because bruce is too much fun to tickle
clark is also very ticklish, but he openly admits that he finds it fun and isn't embarrassed by this fact at all
his sides, stomach, and knees are all super sensitive
he also associates it with his childhood with ma and pa kent, and he just loves physical affection and laughing and letting loose
bruce isn't used to being on the giving or receiving end of all that affection/attention, but it oddly feels easier to receive it...it's less effort to lay there and laugh than it is to be the one doing the tickling, wondering if he's doing it right and if clark is having fun
he likes the way that tickling makes his brain shut off, and clark is more than willing to assist him in the regard
bruce does still get his revenge sometimes, and clark just has the sweetest, giggliest laugh in the universe that makes everyone melt
whereas bruce flips between making odd grunts and whimpers, to letting the giggles slip out, to belly-laughing, and back to trying to hold it in all within a matter of minutes (it's all still cute, too)
