Hi all, it's Pandora! :D Holly asked me for a fic of Kaminari riding Shouji's dick in a thunderstorm and here is what I wrote for her! I hope you all enjoy it! :)

Running a hand over his face, Mezou blinks at the email in front of him again and sighs. Either the person who wrote it is illiterate—which would be a real problem given they're his tutor for Ethical Heroics—or he simply can't concentrate any longer. After several straight hours working on his essay plan and reserving all the books he'll need from the university library, he's inclined to believe that it's the latter. He's been fighting a pressure headache all day too—several days of no rain and mounting air pressure always makes his head hurt a little and studying harder, never mind work days. Hopefully the pressure will drop soon—for today he suspects he's not getting anything else done.

Footsteps stomp along the walkway outside and Mezou knows who it is even before he hears the jingle of keys in the lock and Denki's voice at the front door.

"I'm home!"

Anyone else would hear no affectation in Denki's voice, just the usual cheerfulness bordering on obliviousness they would expect, but after so many years together Mezou can hear a tension there, a tightness that isn't usually there.

"Welcome home," Mezou calls, shutting down his laptop. He hears Denki shuffling around by the front door, taking off his shoes and hanging up his jacket before padding into the room in his socks. As Mezou closes his laptop, Denki comes up behind him and wraps his arms around Mezou's shoulders. "Hey Lightning Bug."

"Hi." Denki's nose nuzzles into Mezou's hair behind his ear, his arms tightening around Mezou's shoulders as he inhales. "You smell good."

"I showered," says Mezou with a little smile, patting Denki's arm. "How was class?"

"Hard," replies Denki; Mezou can feel him frowning against his ear.

"Lots of difficult questions?" Mezou asks.

Denki nods. "Couldn't concentrate."

"Did you voice record it so we can go over it together later?"

Again, Denki nods. "Wasn't just that though."

Mezou barely has time to ask "no?" before he feels Denki's teeth grazing his earlobe, his tongue following in their wake, and suddenly Mezou knows why Denki couldn't focus.

"There's a thunderstorm coming," Denki murmurs—unnecessarily but Mezou can't help the tingle in his scalp at the tone of his voice. "I can feel it."

The weather forecast has said nothing of any storms, but Mezou trusts Denki's inner barometer absolutely: he's never been wrong yet, after all, and the prospect of a storm and falling air pressure is too welcome to brush off. Denki bites gently on Mezou's ear again, tugging it between his teeth a little before licking it once more.

"Are you busy?" he asks.

"No," replies Mezou, enjoying the feeling of Denki's lips. "I couldn't concentrate either."

"Pressure headache?" Denki's tone grows quietly concerned. "Can I help get rid of it?"

Slowly, Mezou turns in his chair, one hand cupping the back of Denki's head to pull him in for a kiss. Denki's lips part and Mezo takes the invitation to slip his tongue past them, touching it to Denki's and being rewarded with the softest little whimper. On his shoulders, Mezou feels Denki's fingers tightening and loosening as they sink into the feeling of one another, yielding and chasing in turn. By the time they part, Denki's cheeks are sweetly flushed, soft and pink, and his golden eyes have taken on a darker hue like honey. Mezou runs his fingers through Denki's hair, caressing the back of his neck, and feels him half buzz and half purr in response.

"Want to go take a shower?" he suggests to an eager nod from Denki. "I'll meet you in the bedroom."

Now that he knows a storm is coming, Mezou isn't sure how he missed the signs. The sky outside is a darker grey and the wind that cuts through the street as Mezou opens the window is blustery, skidding fallen brown leaves into the gutter. He pulls shut the fly screen and turns on the bedside lamp, soft golden light filling the room and making it cosy instead of gloomy. Rolling the duvet up, he takes it off the bed before getting their extra large bottle of lube and leaving it on the bedside table where he'll be able to reach it later.

Just as Mezou hears the first quiet rumbles of thunder in the distance, Denki appears in the bedroom doorway, his towel hanging low on his hips and body flushed with anticipation. Mezou gives him a little smile.

"Good shower?" he asks, to a nod from Denki. "Sounds like it's here."

A flash of lightning briefly throws the room into stark relief and Mezou gets but a second's warning before Denki pounces on him, leaping into his arms for a hungry kiss. If Mezou were less huge, the move would have thrown him back onto the bed, but as it is his strong arms hold Denki close, two hands under his ass while the others move up and down Denki's body, running through his hair and enjoying the feeling of his skin. Denki's towel disappears somewhere in the melee and as they hear a crash of thunder Denki presses himself needily on Mezou, grinding against him with a whimper. When they part again, Denki is panting.

"Want you so much," he murmurs; Mezou can feel how true the words are; Denki's need buzzes under his skin and raises goosebumps on Mezou's.

"Want you too," says Mezou, sinking down onto the bed with Denki in his arms. Denki's hands move down to pull up the hem of Mezou's top, tugging it up and over his head before kissing him again. He moves his touches over Mezou's skin, stroking over his pecs and abs as they listen to the sound of the rain pouring down outside. As they part for breath, Denki starts trailing kisses down Mezou's neck and Mezou grips his hips hard with two hands, grinding up into them and getting another whine in response.

Denki's kisses continue down Mezou's body, interspersed with little nips and licks, and Mezou brushes Denki's hair out of his eyes. When Denki hooks his fingers into the waistband of Mezou's trousers, Mezou lifts his hips to let him take them off, followed swiftly by his underwear. On his knees between Mezou's legs, Denki wastes no time before opening his mouth and running his tongue up Mezou's cock.

"Fuck," Mezou breathes, the fingers in Denki's hair tightening a little. He watches Denki dragging his tongue up his cock, another bright flash of lightning illuminating his face. Static jumps between their skin as Denki closes his lips around Mezou's cock, the sensation of his mouth blending with the light buzz; Mezou bites back a groan. He's always loved Denki's mouth and especially how he uses it: his lips and tongue are soft and warm and wet—when he hollows his cheeks and sucks Mezou's dick right to the back of his throat Mezou has to keep himself from grabbing Denki's hair and fucking his face. Denki moans around Mezou's cock, his throat opening more to take it farther in, and Mezou gasps. "Oh Denki..."

Denki looks up at him through his lashes, his cheeks flushed and eyes dark. The look on his face flashes with the next bright sting of lightning and Mezou feels sparks tingling between Denki's tongue and his cock, biting his lip on another groan. After one tiny accident a while ago, he knows Denki won't lose control and shock him (and really it didn't feel that bad—it was more a surprise than anything) so he tugs a little harder on Denki's hair. When Denki whines around his cock again, Mezou shudders.

"You want more?" he rasps; Denki nods but Mezou gently massages his scalp. "Use your words babe."

Denki pulls back, a gleam in his eyes. "Want more."

"What do you want?" adds Mezou; Denki's fingers grip his thighs a little tighter.

"Want to feel your fingers and your tongue."

"Okay sweetie." Mezou leans down and kisses him tenderly before reaching for the lube.

Denki gets on all fours, sucking Mezou's cock back into his mouth as Mezou coats the fingers of one hand in lube and reaches down. With his long arms, he easily reaches Denki's ass and morphs another hand into a mouth. At the first swipe of Mezou's tongue, Denki jolts, and thunder crashes outside, drowning out the moan Mezou feels around his dick. He licks more, slowly and teasingly while his lubricated fingers circle, the first pressing in only gently alongside his tongue. Denki's whine sends another buzz through Mezou as he continues moving his fingers and extra mouth, working Denki slowly open. It's not always necessary to take his time to do it so thoroughly, but he knows how much Denki loves it, enjoys the feeling of anticipation he gets from Mezou taking him apart, and he knows Denki will want it even more with the storm.

When Mezou eventually slides a third finger in, seeking out Denki's prostate as his tongue sweeps in a wet arch, Denki groans afresh and rocks his hips back into the touch. Mezou grins to himself and continues, feeling Denki's body trembling under his ministrations; he knows every touch will be amplified and intensified by the storm outside, Denki's nerves a lightning rod. More soft little moans leave Denki, his tongue and lips getting wetter around Mezou's cock as Mezou keeps winding him tighter and tighter. Eventually it gets to be too much for Denki and he pulls off Mezou's cock with a wet gasp.

"Mezou," he whines plaintively, the sound almost lost under the next rumble of thunder. Mezou looks down at him with a smirk, self satisfaction thrumming through him, and sees Denki's tear filled eyes gazing up at him.

"Feeling good?" he asks, thrusting his fingers in a little harder and feeling Denki clench harder around them. "Feels like it."

"Need you!" Denki moans; Mezou can see his hands on the floor, fingers curled tightly around the edge of the rug. "Please fuck me!"

Mezou grins down at him, still working his fingers and tongue. "You want to ride me? Get me nice and deep?"

"Fuck yes, please!" Denki begs, rocking his hips back more. "Fucking need you so much!"

"Well you've asked so nicely." Mezou withdraws his fingers and the extra mouth, shuffling back on the bed to lean against the headboard as Denki follows him eagerly. As Denki straddles his hips, Mezou coats his cock in even more lube before guiding Denki down onto it, kissing down his neck as Denki moans desperately.

The rain drives down harder outside, the lightning flashes becoming more frequent and the thunder getting louder right over their heads, and Denki starts moving in Mezou's lap, fucking himself on Mezou's cock. His cries of pleasure are almost swallowed by the storm, becoming a sound for Mezou's ears only as he rides Mezou hard and fast.

"Oh fuck!" Denki gasps as Mezou grips his hips with two hands to meet Denki's movements and drive deeper into him. He arches his back in a bid to get him even deeper, his next moan catching in his throat as Mezou uses his extra mouth to lick Denki's nipple. "Shit, feels so fucking good!"

Mezou drags the extra mouth down Denki's chest and stomach, licking and biting like Denki did to him earlier, until eventually he can tongue up Denki's dick as Denki continues riding him. The quivering moan Denki releases at the feeling of Mezou's lips wrapping around his cock is the single most gorgeous thing Mezou's heard all evening.

"This okay?" Mezou asks softly, to a nod from Denki.

"Yeah, feels amazing, please don't stop!"

Mezou continues, taking Denki's cock right into the back of his extra mouth and dragging his tongue along the underside. A shudder goes through Denki, his fingers tightening on Mezou's shoulders again as he keeps moving, hips bucking forward and back as he tries to chase both sensations. One of Mezou's hands cups his ass to help him find a good rhythm, and Mezou knows he's found it when Denki's moans get higher and his movements speed up more.

"Oh my god, oh my god..." More flashes of lightning light up tear tracks starting to make their way down Denki's face and his eyes are half lidded and unfocused. "Mm... Mezou..."

Thunder rumbles overhead and Mezou pulls Denki in for more kisses. "You okay darling?" he asks. "You look so good taking my cock while I suck you off."

Denki lets out another desperate moan, sparks crackling under his skin. "Love it so much, love feeling you in me, fuck, I'm so close!"

As the loudest crack of thunder and brightest flash of lightning yet seem to shake the room, Mezou grips Denki's hips harder again and thrusts up into him, giving one final hard suck with the mouth around Denki's cock, and Denki comes hard, mouth falling open in a wordless scream. It doesn't take long for Mezou to follow, coming as Denki clenches around him and groaning into his hair. For a long few moments, Denki's body seems electrified, frozen in place with the force of his orgasm, before he flops forward in Mezou's arms to rest against his chest. Mezou pulls the extra mouth off Denki's cock, turning it back into a hand as he pulls him close and hugs him, kissing him on the forehead. Denki pants against his neck, sweat sheening his whole body, and Mezou hears the thunder growing quieter as the storm starts to move on.

"You okay?" Mezou asks, catching his own breath too and cradling Denki in his arms. Denki nods and murmurs vaguely, too exhausted to fully form his words. "Feeling less tense?"

Denki looks up at him with a lazy grin, drawing him down for another soft kiss. When they part again, he breathes against Mezou's lips, "Yeah, 'm happy. How's your head?"

Mezou nods. "Much better. Love you."

"I love you too."

They trade slower kisses, sinking lower on the bed until they lie flat together, curled up on the sheets as they listen to the falling rain and slowing wind outside.
