Who Needs Swimsuits? (смешанная)

It's miserably hot. Nobody can argue otherwise, and even though his sweat's got powers, Bakugou is as miserable as all the rest of them as they trek back from a long hike down the mountain, their damn clothes sticking to their bodies. And he doesn't dare light up to dry off because it's hot as BALLS out here. Even Todoroki's sweating. Not like he's got anything that can make that easier, though, Bakugou thinks, his thoughts dripping with as much sarcasm as there is sweat down his eyebrows.
When they finally reach the mountain's base it's an immense relief. And after a mile or so, their path starts to run parallel to a river. It's brown and grimy and probably disgusting but as soon as Kirishima sees it he's absolutely obsessed. "Guys. We absolutely have to go swimming."
"Ehhhhhh... I didn't bring a swimsuit." Deku is the first to object. And for once, Bakugou feels the need to back him up on his idea because it's not shitty. "Plus the water looks pretty grimy..." Make that twice, damn him.
