Kirishima Eijirou did not share his phone password with just anyone. But long as any of his friends could remember Kirishima had an open phone policy. Meaning that I a friend needed his phone for anything, to look something up, as a distraction, to take a quick photo, or to text someone, or literally anything at all, then the red head would hand the device over no problem. It never bothered Kirishima when his friends went through or used his phone. At times it even made him feel useful in everyday life.
Because of his open phone policy all of his friends knew his password at all times. Didn't matter if Kirishima changed it, got a new phone, or someone changed it without telling him as a prank (Denki), all of his friends knew his password at all times no matter what. This had never been a problem for the red head. He bearly used his phone besides to text his friends and even then he trusted his friends not to snoop into personal territory. (Despite the fact that Denki pushed those limits daily) He never felt like he needed to hide anything.
Then Kirishima started dating Bakugo. Now, once Bakugo found out about the open phone policy he made a point of not allowing Kirishima's (their) friends to not look through any personal chats Bakugo and Kirishima shared. The red head agreed and even went as far as to put a lock on his messaging app that only a few trusted people had. (Certainly not Denki) After Bakugo confirmed that their private chats would stay private, he never complained about the open phone policy again. And it wasn't even Bakugo that had suggested Kirishima keep his phone private.
No, I'm fact, Kirishima had decided all on his own that he needed to keep a tighter cap on who went through his phone. Now, he didn't come to this conclusion because anyone had crossed a boundary. (Despite how hard Denki had tried.) And Bakugo hadn't even told him to stop letting people on his phone, the blonde didn't care as long as private conversations stayed private. So why did Kirishima suddenly change his password and only told his boyfriend the new one? It's simple really.
On a rare day alone with Bakugo
Kirishima's mouth fell open in a moan as Bakugo finally wrapped his lips around the red heads cock. Bakugo began a slow, almost torturous pace. Kirishima tightened his grip in the blondes hair, gently rolling his hips forward in hopes that Bakugo would go faster. Bakugo simply hummed and continued to bob his head slowly.
"Kats- please!" Kirishima felt his hips start to shake at the effort to stay still. Bakugo's eyes were filled with list and pride as he continued to tease the red head. Soon enough Kirishima couldn't take it anymore. The red head groaned out before holding Bakugo till with his hands in his hair and around his neck. The blonde could easily pull out of his grip, but Bakugo simply moaned around Kirishima and let his jaw and throat fall open.
Kirishima whimpered as he began to piston his hips into the blondes mouth quickly. His hips stuttering at every sound the blonde let out. Kirishima was embarrassingly close, but he couldn't find it in himself to really care. Especially not when Bakugo's eyes were hooded over, when his cheeks were flushed a bright pink, when his nails dug into Kirishima's thigh. Bakugo looked thoroughly fucked out and Kirishima found himself holding the blonde against his pelvis as he came.
To Kirishima's surprise, the blonde chocked at the sudden movement and pulled away suddenly. Kirishima groaned at the loss of the warm heat around him but couldn't find it in him to complain when he looked down at the blonde. Bakugo's throat bobbed as he panted softly. His hair was a mess of spikes, his eyes nearly rolled back, his tongue hanging out slightly. On top of that, Kirishima could see his own cum coating the inside of Bakugo's mouth, his spend covered his tongue and the back of his throat. The best part? Bakugo had pulled away before Kirishima had finished cumming. Meaning that ropes of cum were splattered across his cheeks and lips. He looked like a cum drunk whore, and Kirishima couldn't help himself.
"Holy shit- babe, stay just like that okay? Just hang on-" Bakugo bearly registered what Kirishima had said but didn't move an inch. Kirishima leaned to the side slightly before coming back holding his phone. "Just wanna capture this for the spank bank." Kirishima looked down at Bakugo, silently asking if this was alright. Bakugo thought it over before pushing his tongue out a bit more, allowing his eyes to roll slightly. The red head groaned but held the phone above Bakugo's face. Snapping a few shots before tossing his phone on his bed and quickly helping his boyfriend clean up.
Later that night when Bakugo was asleep in his arms Kirishima looked back over the photo he took. He couldn't get over how fucked out the blonde looked. Kirishima quickly decided that for the near future he'd have to see this photo at least once a day. So without much fuss he quickly changed his home screen from a Crimson Riot photo to the photo of Bakugo. The red head smiled, proud of his work. Then he thought about people potentially seeing said photo when they opened his phone.
Kirishima made quick work to change his phone password before closing his phone. Placing it on his nightstand before cuddling up to Bakugo. In the morning Kirishima's alarm rung out into the silent room. The red head groaned and grabbed his phone to turn it off. After shitting the alarm off, he was greeted by his lock screen, a picture of him and all his friends, although he had his cheek pressed against Bakugo's. Kirishima typed in his old password half asleep. Confusion seeped into him when his phone didn't open. Then he remembered he had changed his password, although he couldn't understand why.
Kirishima typed in his new password while he tried to clear up his brain fog and remember why he'd changed it. Then he came face to face with his home screen. Bakugo's fucked out face covered in his cum stared back at Kirishima. The red head flushed before shutting off his phone. After sitting for a moment, he grabbed his phone again. He opened it and simply stared at the photo.
Kirishima was suddenly very proud of himself.
Present
So yes, Kirishima decided to keep the new home screen. And effective immediately, refused to allow anyone but him and Bakugo know his new password. Not willing to share the golden photo that was his home screen. After Bakugo had seen it he gave Kirishima a disappointed look but said nothing. Basically meaning he was judging Kirishima but not objecting to the red heads decision.
Kirishima spent the next few weeks skillfully dodging his friends questions while holding his phone close. Only allowing Bakugo to handle it if he didn't have it. However, Kirishima's guilty pleasure would soon come to light....
"Bro! Sero just got the new Mario cart! Wanna come play with us?" Denki walked up behind Kirishima on the couch. The red head turned from where he was watching TV and smiled.
"Sure! Let me just text Katsuki and ask if he wants to join!" Denki nodded and moved to rest against the back of the couch. Now, in Kaminari's defense, he hadn't meant to snoop. Let alone see anything. But the blonde couldn't help his curious gaze when the red head began to open his phone. Denki was about to look away, respect his bros privacy. Honest! Scouts honor! But, before he could, he saw it. The photo Kirishima had spent the last few weeks hiding away.
Denki's eyes widened as he took in Bakugo in a very private state. The photo was only visible for maybe a second, but it was more than enough for Kaminari to get the gist. Bakugo, on his knees, eyes rolled, and face covered in cum. He had to admit, it was a nice sight. If not for the fact that it was HIS BEST BROS BOYFRIEND and not some random porn actress he'd stummbled across.
Kirishima looked over his shoulder and said something to Kaminari. But the blonde couldn't hear him. His brain was fried from the image he'd just seen. Out of pure embarrassment and a surprising amount of horniness that ran through him Denki shot up. He made some excuse about not feeling well all the sudden and told Kirishima to go ahead without him. Kaminari spent that night painfully hard but refusing to touch himself. It just felt way to wrong.
In the next two weeks Kaminari promptly avoided Bakugo like the plague. This obviously made the firey blonde confused but he didn't push it. After those two weeks Denki finally felt like he could look Bakugo in the eye without seeing his face covered in cum. Then a new problem arouse, Kaminari had never noticed before but, Bakugo rolled his eyes. A lot. Like. A lot a lot. Kaminari Denki felt stuck in a horny prison of constantly seeing Bakugo in such a compromising position. Popping a boner and any noise or sudden eye roll the blonde made. And the worst part? He couldn't tell anyone. Especially Kirishima. So here he was. Stuck and miserable.
Denki Kaminari would from then on refuse to look through anyones phone for any reason. And despite the fact that Kirishima changed his home screen eventually and allowed people to go on his phone again, Denki could never truly get that image out of his head. And he didn't know what pissed him off more, the fact that seeing Bakugo that way did something to him. Or the fact that he refused to do anything about it so now he was constantly hard and suffering from blue balls. He hopes Kirishima knows what a good friend he is after all this is over.
Oh Kirishima knows. He had to find some way to get Denki back for his constant boundary pushing. It wasn't always the plan, but seeing Denki suffer with that image for months after? Made it completely worth it. Best part? Bakugo would never know. And Kirishima could keep ogling his boyfriends picture any time he wanted. Win win in his book.
Bakugo stayed in the dark until years later when Denki drunkenly confessed to him that the photo made him rethink some things about himself.
Kirishima was then banned from using any nudes or explicit photos of Bakugo for his home or lock screen. Bakugo also forced the red head to struggle with blue balls for a month and a half.
Kaminari never did get an apology.
