Their First Time

Continuation of Concept 2. Bet some of y'all have been waiting for this one. And yes, this is another first time chapter. I can't help it, I love them.
CW: Trans!Bakugou, Pre/Post op body, protected sex, sexting, first time

Recap: KRBK just moved into their apartment and were planning something ~special~, but Bakugou got dragged off on a month long summer trip with his parents. Will that stop him from getting sexy with his boyfriend? Hell fucking no.

The two of them kept in touch of course, but they couldn't FaceTime often since Bakugou was very rarely alone, the times he is alone being mainly bathroom breaks. However, he takes advantage of those whenever he can. He starts out simple. He sends a picture of him in nothing but some dope looking swim shorts.
'The hag got me a new bathing suit.'
'Woah! Those are awesome! You look manly as hell babe!'
Yeah, that was sweet, and Kirishima got another good picture of his boyfriend! He's glad he's having fun! They're innocent things like that at first, but after the third picture, Kirishima starts thinking it's a little odd for him to be sending pictures so frequently. He shrugs it off for now. He sends pictures regularly, himself, and Bakugou amps up his approach one day when his boyfriend sends him a mirror selfie after his morning workout. He has to hide in the bathroom of the hotel and pretend to be taking a piss so his parents wouldn't see him blushing. He's blushing because in the picture, Kirishima is shirtless and flushed and sweaty and flexing and holy shit he looks fucking delicious.
'Told you I wouldn't get chubby while you were gone! Gotta keep the hugging machines in tip top shape for when you get back!'
'Damn, Shitty Hair, is hugging all they can do to me?'
...
'I think the machines are overheated and need to cool down. Gonna hop in the shower before work. Love you, Katsuki!'
'Love you too'

After that the flirting mutually got more frequent, and after about two weeks, Bakugou got the opportunity to amp his approach up again. He couldn't sleep one night because he had been an idiot and taken a long ass nap hours before. He got bored in the hotel room real fast, and decided to head down to the hotel's hot tub since nobody else was there. He got bored in there too, but after a few minutes, he decided this would be the perfect opportunity to tease his boyfriend. He peeled off his swim shorts and got his phone.
'You up, Shitty Hair?'
...
'Yeah. Isn't it past your bedtime?'
'Fuck you. Couldn't sleep. What are you doing up?'
'Watching movies. Couldn't sleep either. Miss you too much. What are you doing?'
'Skinny dipping.'
...
'No you're not.'
'Yes I am.'
'Prove it.'
Hook. Bakugou sends a picture of the bubbling water.
'Ok. Hot tub. Still not proof. The bubbles hide your legs.'
Line. Bakugou smirks and lifts himself onto the edge of the tub. He crosses his legs to obscure his crotch, and takes a selfie...and that was not what Kirishima was expecting to see. A picture of his swim trunks, maybe, but not...holy shit.
'Ok. I believe you now.'
Sink.

From there, flirting evolved into foreplay. The next week, Bakugou took as many opportunities as he could get to send his boyfriend borderline nudes, or just very suggestive pictures. His shoulders and cheeks got a little sunburnt, and when he was ranting to his boyfriend about it, he sent him a picture. It wasn't too bad, and the rosy hue his skin had developed was just faint enough to make the burn look like a blush, and Kirishima couldn't get over that sight. He thought about it the whole next day. One day it was practically boiling hot, and he sent Bakugou a quick text to stay cool. Bakugou snagged that opportunity as well. He had stayed in the hotel that day so his sunburn wouldn't get worse, plus there was air conditioning. He laid on his stomach on his bed and sent a picture of him licking the popsicle he'd ordered from room service. That one sent Kirishima into a flustered gay panic, and he ended up being the one that needed to cool down...in more ways than one. It was then that he realized what he was doing, and it was all uphill from there. They were sending pictures and flirty comments back and forth until a few days before Bakugou would be back, and at that point, they upped the game on their foreplay. They were texting the night it escalated.
