"Katsuki and you have been roommates and friends with benefits for over a year already. The two of you do intimate things together without any real feelings involved." "You’re in the kitchen making dinner when Katsuki came back from training and walked into the kitchen." "He slowly approached you from behind and pinned you against the counter as he started kissing your neck and undid his belt." “Be a sweet thing and let me get rid of some stress, yeah?”

"Katsuki takes a moment to process your response before pulling back slightly and looking at you."

"What's the matter, Luna?" "he asks with a raised eyebrow." "You know how I get after training. I need this, and you need it too."

"Katsuki's expression changes to one of mild annoyance upon hearing your reply. He leans back a little, keeping his hands on your waist."

"And why not?" "he asks, his voice carrying a note of impatience." "Do you have someone else over or something?"

"Katsuki's expression softens a bit upon hearing your reason. He leans in closer again, pressing his body against yours and nuzzling against your neck."

"Well, why didn't you say so?" "he murmurs, his voice low and husky." "I'll just have to find another way to release some stress tonight."

"He presses a kiss to the sensitive area behind your ear before pulling away from you completely." "I'm going to take a shower. You want to join me?"

"Katsuki just chuckles at your question, his previous annoyance completely vanished now."

"Why would I be mad?" "he asks, arching an eyebrow." "It's not like you can control that stuff. And anyway, I don't just use you for sex, despite what you might think. I like spending time with you, period or no period."

"He pauses for a second, then smirks and adds," "Although, sex is definitely a huge plus."

"Katsuki rolls his eyes at your question, then takes a step closer to you and holds your chin gently, making you look up at him."

"Why would I lie about something like that, huh?" "he asks softly." "You mean a lot to me, Luna, and yeah, the sex is amazing, but that's not the only reason I keep coming back to you."

"He leans in and presses a gentle kiss to your lips." "Now come on," "he murmurs," "let's go take that shower."

"Katsuki smirks at your response before taking your hand and leading you towards the bathroom. Once inside, he turns on the shower and waits for the water to heat up before gesturing for you to step under the spray with him."

As the hot water cascades down over both of you, Katsuki leans against the shower wall and pulls you close, pressing his lips against yours in a deep, passionate kiss. His hands roam over your body as he kisses you, exploring every inch of your skin.

After a few moments, he breaks the kiss and steps back, reaching for some body wash and pouring a generous amount into his hand. Without a word, he begins to massage the suds into your skin, his touch gentle yet possessive.

"God, you're so fucking beautiful," "he murmurs as he washes you."

"Katsuki pauses his ministrations on you for a moment and looks down at you, surprise showing on his handsome features."

"Of course, I mean it," "he says, a sincere tone in his voice. He then resumes scrubbing your body with the shower gel as he explains," "Luna, you're one of the most attractive people I've ever been with. Being around you turns me on so much, and seeing you like this - wet and naked under the running water - is incredibly sexy."

"He grins playfully at you before leaning down to kiss your neck." "Don't try to deny it, you know it's true."

"Katsuki grunts softly as you hug him, but he doesn't resist. Instead, he wraps his arms around your waist and holds you close, nuzzling his face against the crook of your neck."

"You deserve to be treated nicely," "he murmurs." "And it's not like I'm just being nice for the hell of it. I really do care about you, Luna."

"He presses a kiss to your collarbone before pulling back slightly."

"Katsuki's expression darkens as he hears your words, his grip on you tightening slightly."

"Well, that's not fucking okay," "he growls." "Anyone who treats you like that doesn't fucking deserve your time or attention. You're perfect the way you are, and anyone who can't see that is a piece of shit."

"He takes a step back, his eyes blazing with anger." "If anyone ever talks to you like that again, you let me know, got it? I'll kick their ass, no questions asked."

"Katsuki returns your hug, holding you close for a few moments before pulling back and looking down at you."

"Hey," "he murmurs," "you don't have to put up with assholes like that, Luna. You deserve someone who treats you like the amazing person you are."

"He reaches up to tuck a strand of hair behind your ear." "And if you're willing to let me be that person, I promise I won't let you down."

"Katsuki nods firmly, a determined look on his face."

"Really," "he says." "I care about you, Luna, and I want to make you happy. I know we're friends with benefits and all, but that doesn't mean I don't have feelings for you. You're an incredible person, and I feel lucky just to know you, let alone have you in my life this way."

"He hesitates for a moment before continuing." "Look, I know I'm not great at expressing myself, but I mean it when I say that you mean something to me. So if you ever need anything from me - anything at all - just ask, okay?"
