I have sinned deeply. If you don't like smut I advise you skip over this. Idk it's like 3 in the morning and I got bored lmao. Art is not mine, I hope you enjoy, and if it sucks i'm sorry I'm still improving in stuff like this. Also story is somewhat based off the image.
"Ugh, that training was so boring!" Kirishima whined walking into the locker room, "It was okay I guess, but it made no sense." Kaminari added taking off his shirt and opening his locker. "Don't be ridiculous it was obviously for the purpose of learning how to properly save a citizen in danger!" Iida retorted motioning his hands. Of course no one paid attention to him and continued to change from their hero outfits to their uniforms.
"Hey, has anyone seen Midoriya?" Todoroki asked putting his shoes on. "Now that you mention it I haven't seen him since he and Bakugou went to the nurse." Kirishima mentioned. "They most likely went back to the class, which is where we should be now." Iida said opening the door and everyone walked out with a groan.

Izuku couldn't believe what he did, he lied to his teachers so he and Katsuki could meet in the locker room before anyone else. He knew what was going to happen, and he was okay with it, but he would never lie to do it. "K-Kacchan.. this is a really bad idea.." Izuku squeaked holding back a moan as Katsuki bit and sucked on his neck. "Stop complaining when you're this hard." Katsuki spat as his hand delicately touched the growing bulge in Izuku's pants.
Izuku gasped biting his knuckle as Kacchan continued to rub him through his pants. Izuku leaned up kissing Katsuki and wrapping his arms around his neck, he couldn't even remember how nervous he was before as he got lost in their heated kiss. Katsuki pulled apart picking up the smaller boy, and placing his hands under his thighs to keep him up against the locker.
Izuku kept his arms on the blondes shoulders, kissing him again, and again. Katsuki pulled away the part of Izuku's shirt covering his shoulder and began to bite at it and leaving small kisses. Kacchan scoffed at him telling him to shut up when Izuku moaned out his name loudly, as he brought his attention back to Izukus neck.
Katsuki pulled his pants down slightly bringing one hand to Izukus mouth, "Suck on them." He commanded sternly. Izuku obeyed sucking on the blondes fingers swirling his tongue around them. Katsuki pulled his hand back when he was sure that they were good. He moved Izukus boxers out of the way and he inserted a finger into Izuku causing the boy to moan quietly. Katsuki smirked watching the boy and he inserted another one beginning to scissor the boy moving his fingers.
Katsuki removed his fingers aligning himself up with Izuku, "Are you sure about this?" He asked Izuku. The boy simply nodded in response still trying to calculate what was happening. Katsuki smirked at him slowly pushing himself in. Izuku moaned out loud not trying to hold back the lewd noises he was making anymore.
Katsuki waited for Izuku to adjust and he knew he was okay when the boy started to buck his hips onto him. Katsuki started with small thrust getting faster, and harder with each one. Izuku moaned loudly bringing one arm down to the blondes back scratching him and putting the other against the locker to secure himself. Katsuki had brought his arms back to Izukus thighs gripping them as his thrust got wilder.
"Mhm..ah.. Kacchan~" The locker room was filled with Izukus moans and the sounds of Katsuki thrusting slowly into the green haired boy. Izuku moaned loudly and Katsuki knew that he hit Izukus sweet spot. "R-Right there Kacchan, t-there~" he moaned, his grip on Katsuki's back getting tighter scratching the boy.
Katsuki winced as Izuku started to dig his nails into his skin. "Kacchan!" He moaned as Katsuki thrusted hardly into him hitting his sweet spot. "Shut up, someone will hear." Katsuki said through gritted teeth as Izuku tightened around him.
"Ugh, that training was so boring!" The two heard Kirishima groan out in complaint. Izuku immediately covered his mouth to muffle his moans. He gave Katsuki a pleading look that read for him to stop, but he continued thrusting into him. "Hey, has anyone seen Midoriya?" Izuku heard Todoroki ask and he froze. He couldn't imagine the embarrassment he would feel if his classmates saw him in the position he was in now.
He prayed to every god out there that they wouldn't find them and he was even more relived when they all left.
"Kacchan,...coming!" Izuku cried out wrapping his arms around the boy as he came onto his hero costume. Katsuki continued to thrust into the boy until his came in him with a groan. Panting Katsuki put Izuku down, and the boy started mumbling about how bad it was that he came inside.
They walked into the showers and Katsuki helped Izuku clean up. When they were done they got dressed, and walked to class. Izuku had a bright obvious blush as he sat down, he wouldn't be able to look Katsuki in the eye for a while.
(Bonus)
"Ah crap I left my phone I'll be right back." Mineta said turning back to the locker room. "Ah, Kacchan~" Mineta heard as he walked in. "What the hell?" He asked when it hit him. They're people having sex during class. He excitedly walked towards it hoping to see a girl based off the moans he had heard. He hummed turning the corner to see none other then Katsuki Bakugou and Midoriya Izuku fucking against the lockers.
"Kacchan t-there~"
He was shocked and didn't know what to say so he grabbed his phone and walked back to class and said nothing after.
This was a bad idea, like I said sorry if it sucks im new to lemons and stuff...
