Warning: sexual stuff :O 

"Dont you understand just how much i love you? How much i would do for you izuku?" 

Katsuki is watching izuku change from the window of his room, like he always does. Spying on his childhood friend when he is in his room is one of katsukis favorite pass times, especially when izuku is changing with his window open all for katsuki to see. Hes never gotten caught, not even once, and katsuki thanks whatever god is out there every time. Izuku, with his back to the window, takes off his shirt, showcasing soft freckled skin so pale and smooth katsuki wants to reach out and touch it. Izuku turns, rummaging for something in his dresser next to the window, letting katsuki see the pink buds hardened by the cold air. Katsuki sharply inhales, feeling his pants tighten. 

izuku, giving up on looking for the object, proceeds to take his pants off, slowly. Katsuki was always frustrated with this, izuku going so slow when katsuki wants to see what he looks like now. Izuku finally takes his pants off and what he sees makes katsukis breath get caught in his throat. Izuku is wearing small, laced underwear that barely covers anything and katsuki has to suppress a small sound that comes from his mouth. Izukus round ass practically begs to be touched and katsuki wants nothing more then to do so. Izuku puts his arms up, stretching. Katsuki quickly unzips his pants, freeing his raging hard on. 

Izuku bends down to pick up his pants, his ass facing right to the window. 

'You look so perfect izuku..' 

katsuki palms himself through his underwear and izuku continues changing, slowly and carefully. Katsuki climaxes all over his underwear and lets out a muffled moan. Izuku puts on his new set of clothes (Red shorts and a grey shirt with T-Shirt written on it) He then goes to the window, grabs the curtains, then looks directly at katsuki with his cum stained underwear and disheveled hair and fucking smiles. Those emerald eyes stare into katsukis blood red ones. 

"See you later Kacchan." 

Katsukis heart drops and his eyes widen as izuku shuts the window and the curtains. Katsuki sits there, shocked. He doesnt know how long he sits there. 

He knew 

Izuku, perfect sexy izuku midoriya knew that katsuki was masturbating to him as he changed. Had he always known? Is that why he changed so slow it made katsuki go crazy? Or why he wore those under- Katsukis face turns red and he quickly shuts his eyes at the thought that enters his brain. 

Was he doing it for him? 

Katsuki struggles to fall asleep as he is back in his bed. A thousand different thoughts enter his mind now that he isnt busy with something else. What if izuku tells everyone what he did? What will his mom and aunt inko think? His dad? What about izuku? Does he think hes gross? No if that were the case then why call out to him, why not tell someone, the police  for example. He would if he wanted to right? 

Does that mean hes actually into it? Damnit! Well look at the bright side, he doesnt know about everything else, whats peeking on him compared to all of that? Katsuki turns around in his sleep over and over again, nerves all throughout his body making it impossible to rest. Worse things.. Like when katsuki stole on of izukus shirts and underwear when he was over for dinner with his family, or when izuku was sick and katsuki took the rag he used to put water on his head, or when he followed izuku all the way home so he could pretend they were walking home together or that one time when katsuki carved izukus name on his leg because he missed him

When katskis hand brushed izukus and he freaked out so much he let out an explosion right at izukus wrists or when inko asked katsuki to install cameras on the porch with motion detection that is also connected to katsukis phone and computer so he could know whenever izuku left or when they were both playing video games together and they brushed arms katsuki yelled and stormed off, so embarrassed. When katsuki skipped school to go into izukus room to lay in his bed and pretend he shared it with him or- 

yeah ok thats enough- Katsuki groans into his pillow in frustration. What is he going to do if izuku ends up hating him? Katsuki doesnt remember when he fell asleep, only when his lord alarm blares in his ear, waking him up. He gets ready and forces himself out the door, which, lo and behold, opens the way to emerald eyes that haunted his dreams and thoughts all the night before. 

"Kacchan. Walk to school with me."

Katsukis face heats up and his hands get sweaty. Normally his heart would be filled with pure joy that his izuku asked him to walk with him (more like demanded) but knowing that izuku knows something he shouldnt poison the mood with nervousness and fear. Katsuki says nothing when he stands next to izuku and they both start walking.

 "So, do you like my body kacchan?"

 Katsuki turns even more red, looking straight ahead to aviod looking at izuku.

 "Listen Deku it isnt what you think-" 

"So you dont like my body?" 

katsuki can hear his own heart beating throughout his body. 

"I never said that." 

Izuku waits, both of their footsteps on the sidewalk making a 'thump' sound. 

"I love your body." 

Izuku hums

"Is that the only thing you like about me?" 

katsuki stammers but gives in, answering honestly and without delay

"I like how smart you are.. How you push me to different limits even if im a dick to you, i like when you mumble you put your hand on your chin or make gestures or chew on your pencil when your focused, your smile and the way your eyes shine, i like the sound of your voice or when you laugh, i love your hair, how soft it is, i love how when you think no ones watching you, you let out these little squeals when you get so excited or happy or when your always so nice to everyone despite all of them treating you like shit.. When ive treated you like shit." 

Its quiet once again. Izuku laughs, mostly to himself. 

"You know kacchan, you watching me change isnt the only thing i know about." 

katsuki takes in a sharp breath, shocked. 

"W-What?" 

izuku gives katsuki a charming smile. 

"Your a stalker not only a peeping tom. What? You thought i didnt know? I was leaving that stuff for you katsuki." 

Bakugou stops, staring at him. He stops walking as well. 

"So.. You wanted me to take your things and.. Watch you?.."
