If I was in My Hero Academia(Along with some OC's of mine)

Kirishima, Denki and Lexi

It was dark and Kiri was on his computer, just looking for things. "Ahhhh~! I can't find anthing interesting!" He groaned. "Alright, I'll leave it for today." He said, getting up. His hand hit the mouse. He looked back at the screen. He saw a kitty plug on the screen. 'A plug of...a cat?' He thought. Immediately, he starting getting thought of Lexi, wearing the set and moaning his name. 'Why did I think about Lexi all of a sudden?' He thought. He looked at the screen, before walking away. "M-Maybe I just need...to sleep a bit more. Yeah sure!" He said. 

15 days later

'I bought it...now what?!' Kiri thought. "I spent the money I would use to buy a gift for Lexi on this...and now I have no idea what to do with it. What a waste." Kiri said. 'I'll put it away for now' He thought. 'Maybe under the bed.' He thought. "I'll look for somewhere to throw it away later." He said, sliding the package under the bed. "Done! Now I just have to get ready for school. Today will be a great day!" He said. 

Later

'That's what I thought' He thought. "AHHHHHH!" Denki groaned. "Who knew that Mr. Aizawa would give us a pop quiz just starting the class~? This day was going so well! I should have expected it!" Denki said. "Could've been worse, Denki." Lexi said. "What do I do now? Ahhhh...I'm sure I failed most of it." Kiri whispered. 'I need to study more' Kiri thought. "I'm so stressed about it right now...I need something that will make me forget it." Denki said. He glanced over. "Heh. I'll come to your room later! I've got something prepared we'll have fun with! Lexi, you in?" Denki asked. "I guess. I got nothing better to do." She said. "But, I have to study, maybe another da-huh? Kaminari, LEXI?!" He asked. 'I've been decived' He thought. Kiri went to his room and sat down. "He'll surely come to play, maybe he made Lexi join in to. I have to study and take a shower before they arrive. I'll be ready for them." He said, getting up.

Later

A knock came on Kiri's door. He opened the door. "Bro! Lexi-chan!" He said. "Hey~!" Denki said. "Hey Kiri." Lexi said, with a closed eye smile. Denki went in and crashed on Kiri's bed. "WAAAAAAAAA!" He sighed. "I hope you didn't come here just for that." Kiri said. Lexi came in and closed the door. "Nope~. I came to play with you for a little while, I brought Lexi because I want her to join us." He said. 'I knew it.' Kiri thought. "What's with that face?" Lexi asked. "Nothing. I'll just finish drying myself, I'll be right back. Oh, and I don't have any new games." Kiri said, as he left. Denki glanced at Lexi, as she fixed her muzzle. He smirked, got off the bed and pinned her to the wall. "K-Kaminari? What are you doing?" She asked. He pulled down her muzzle and pulled her into a kiss. She slowly kissed back. He trailed his hands up her shirt. Her eyes flew open as she pushed him away. "S-Sorry. I-It's just...you're too fast." She said. He smiled and rubbed her head. "It's okay, I understand." He said. She smiled. "Alright!" He said, as went to Kiri's bed and pulled a box from underneath it.

"That's a lot of games." Lexi said. "I know. We played all of them. There has to be something good around here." Denki said. He saw the package under the bed. 'Nothing new, huh? Hehehe.' He thought. A few minutes later, Kiri came back. "Hey Kaminari, Lexi didn't you both...see.." He trailed off, when he saw Lexi with the cat ears on. "Hey man, this is great!" Denki said. Kiri froze. "Are you cosplaying or something like that?" Lexi asked. "What else is there?" Denki asked, looking in the package. "N-No, wait!" Kiri said. Lexi pulled out the plug. 'NOOOOO!' Kiri thought. "Um Kiri, how do you put it on?" She asked. Kiri froze and sighed.

After explaining

"WAHHHHHHHHHH?!" Denki asked. "Why would you buy this?!" Lexi asked. "I thought it would look good on Lexi!" Kiri said. "Huh?" Denki asked, then he realized. "Ehhhh?? You mean you planned her to use it and left it there on purpose?! I would only expect that from Mineta!" He said. "You're wrong! What the heck's with that guess?!" Kiri said. "I was planning on throwing it away, I thought that making Lexi use it would be inappropriate and unmanly, specially because it's like you." Kiri said, causing Lexi to blush and cover her face. "Weirdo." Denki said. "Ah?! You're guilty as well! Why do you check over people's things without permission?! That package wasn't open!" Kiri said, pointing at Denki. "You didn't tell me not to!" Denki said. "💢Are you an idiot?!💢" Kiri asked. "Uh...am I an idiot?" Denki asked. Lexi deadpanned. "Oh, no, Denki! I-I didn't...UGH!" Kiri said. 'Well...it is my fault. I shouldn't have looked in something that isn't mine in the first place. And, on top of that, I got Lexi involved in something she wasn't even supposed to be in. I brought her to have fun with us, and I won't lie, I'm really curious to see how Lexi will look with this on her.' Denki thought. He looked at Lexi, who was sitting on the bed, looking outside, then back at Kirishima. "You're not an idiot...I just wanted you to see how it's your fault to." Kiri said.
