You had never imagined you would find yourself in this situation, but your friend, Mina, seemed to convince you to tag along with her to an underground BDSM class she had been helping teach for a few weeks, alongside a close friend of hers. You, of course, protested at first, sure you would be out of your comfort zone. Mina insisted she knew the man who taught the class and would do her best to make sure you were as comfortable as possible.

After some convincing, you finally agreed to go along. Mina assured you that she would stay by your side the whole time, assured you that the lesson would be tame this week and that you had nothing to worry about.

Mina gave you a simple rundown of the class, even showed you some of the previous lesson plans so you wouldn't feel completely left out. The subject was so new to you, but you were quite intrigued. She also had you fill out a simple form, explaining the point of the class and the things you may experience. Once you looked over the document, you signed it with a shaky hand.

Now you stood in your room, collecting your things before you had to leave with your roommate. 

“C’mon, We’re gonna be late, babe!” Mina shouted through your shared apartment. 

You let out an exaggerated groan as you walked into the loft, phone in hand, “Are you sure I have to go?”

“You promised! Besides, It’ll be really fun!” She insisted, flashing you a smile, “You need to get out more anyway.” She reminded you.

You knew she was right. While Mina loved to go out and party, you preferred to stay in and watch Netflix. You had never been one to party, it just wasn't like you.

Nerves were running high as you arrived at a building you were quite familiar with, the local library. Your eyebrows knitted together as you stared up at the large building, stopping in your tracks.

“Mina, this is the library? I thought you said we were going to a uh,” you trailed off, not wanting to finish your sentence, “you know.” Cheeks flushed as you insinuated.

“Oh yeah!” The pink-haired girl chimed in, “We rent out the library basement once a week!” A smile covered her lips as she led you into the library and down a shifty flight of stairs.

You hadn't even known the library had a basement, and it was a place you were quite frequent to visit. You wonder if you had ever met the instructor before, even just in passing.

Your mind was racing almost as fast as your heart as you approached a large black door, “Well, here we are!” Mina said cheerily, “There’s nothing to worry about, C’mon!” 

Mina pushed opened the door and all eyes were on you. 

“Sorry, I’m late Katsu! Had to drag this one out of the house!” Mina motioned towards you.

You felt your cheeks heat up as the instructor of the class eyed you for a moment before returning his gaze to Mina. 

You couldn't tear your eyes away from the blonde standing in front of you, something about him was so alluring. Vermillion eyes met yours for a moment before he spoke.

“It’s about time, Mina.” His tone held a hint of annoyance, “Almost started without you.” he scoffed under his breath, “Mina, join me up here,” Katsuki motioned, “and You,” His gaze was set on you, “Have a seat.” a large hand waved towards a table near the front of the room.

You quickly padded towards an empty chair, noticing a sheet of paper in front of you and an ink pen. 

The blonde teacher took his place alongside mina in front of the class. He looked so big and scary, you almost whined when his eyes landed on you again. You felt like you were in a trance as he spoke, his voice sounding like a distant whisper.

“Alright everyone, take a look at those papers in front of you.” The blonde instructor spoke, leaning against a small table that sat at the front of the room. Though, your eyes were frozen on him. Your entire body sat completely still, watching his every move. You quite literally could not look away from him if your life depended on it. 

The way his muscles flexed under his tightly fitting button-up with every move, the slightly see-through material in combination with the overhead lighting allowed for a perfect few of how well defined he was. The material hung ever so nicely on each and every individual muscle. 

You became so engulfed in thoughts about what this man could do to you that you didn’t even notice as he began to walk towards you. Not until you felt a warm hand tightly grip your cheeks, forcing your head upward slightly. Your entire face flushed a bright red, realizing that your new instructor was standing over your desk, your face squeezed in his rather large hand. 

“Paper. Now.” Katsuki growled out softly, his vermillion eyes staring daggers at you. A small squeak left your lips as your eyes shifted down from his to the paper in front of you. The male watched your eyes flick back and forth as you read the material presented to you. His hand released your face, a small smirk on his lips. “Good girl.” He whispered close to your ear, just quiet enough where you were sure you may have been the only one to hear, before walking away from your desk and heading back to the front of the room. You felt your body try to shrink into your seat, wanting to feel as small as possible out of sheer embarrassment. 

“Today we are going over titles. They’re a heavily important part of any BDSM or Dom/Sub relationship. There are some basic titles, along with their definitions written on the papers in front of you.” Katuski grabbed his own paper off of the table in front of him and began reading off the different honorifics and titles written. 

“These titles are important, many of you may already use them in your play or daily life, if so I'm sure you're aware of the significance they hold. For those of you who are newer to the scene, I'll give a brief explanation.” He continued, pacing in front of the class, “They are titles of respect, these are not to be used on just anyone,” The blonde hummed, eyes meeting yours, “They’re saved for someone you trust and respect.”

You took in the information the best you could, but your mind was racing as your eyes scanned the sheet of paper in front of you, you wondered which honorifics your teacher preferred.

“As a dominant, I do not let just anyone call me ‘Master’, or ‘Daddy’, these titles are saved for my submissives only.”

A pout fell upon your lips at his phrasing, you wonder if he has more than one partner already. You wouldn't be surprised if that was the case, he was so handsome, so seductive, everything about him seemed perfect.

“For those of you who are submissive, titles such as ‘Baby girl’, and ‘Princess’ should be saved for someone special. You wouldn’t want someone random calling you that, would you?” He addressed the class and you watched as a few of your peers nodded. 

“Before I continue with the lesson, I would like everyone to circle the names that are of importance to you, or names you would like your partner to call you.”

You stared at the paper once again, thinking of which names you might enjoy. You nervously held onto your pen, circling a few of the names that stood out to you, such as ‘baby’, ‘baby girl’, ‘princess’, and a few others. Some of the names seemed a bit out of your comfort zone, you thought if someone called you some of the harsher ones you may end up crying.

After a few minutes of silence, Katsuki spoke up again, “Alright, I trust that you all have selected a few of the names from the list. I’m going to come around and see what types of titles everyone has selected, just so I can get to know everyone.”

Katsuki strides down the isles, glancing at everyone’s answers. As he approaches you, you find yourself hiding your answers with your arm, growing nervous. 

As he hovers over you, you get a whiff of his cologne, he smells like fire and cinnamon with a hint of mint, “Whatcha hiding from?” He hums, an amused look covering his face, “I don't bite unless you ask nicely.”

Your cheeks heat up at his comment and you let out a squeak, uncovering your answers. His eyes scan over your paper before he flashes you a smile, “Good choices.” he mutters before walking away to the next person.

After a few minutes, he returned to the front of the class and explains more about the importance of titles and when it's appropriate to use them. How certain honorifics are okay to use in certain situations, as long as you have consent to use them. You soak up as much of the information as possible, wanting to impress the blonde if he asks you any questions. 

You find yourself sitting on the edge of your seat by the end of the lesson, taking in everything he's saying as gospel. 

Katsuki wraps up the class by letting everyone know what time they will be meeting next week, and saying goodbyes as people shuffle out of the room.

You collect your things, padding over to your roommate, “Hey babe! How was it?” Mina cheers, flashing you a smile.

Your cheeks flush as your mind races with all of the events that occurred, “It was,” you trailed off, trying to find the right word, “Interesting, that’s for sure.” you gave her a sheepish smile, attempting to cover your flustered state. You really wanted to get home as soon as possible, there was an ache between your thighs that you really needed to deal with.

“Hey pinky,” a gruff voice spoke, causing you to jump, “Don’t forget we need to go over next week's lesson. It’s hot as shit down here.” Katsuki grumbled, approaching the two of you. 

As he stood beside you, you glanced up to catch a peek of his face and you noticed how tall he really was, the man literally towered over you, at least by an entire foot. He must've felt your gaze on him, as his eyes darted down to meet yours, “Hope I didn’t scare ya’ too bad today.” He flashed you a grin before turning his attention back to Mina, “Let’s meet upstairs, I’ll take your friend here with me.”

“Okay, be there in a few!” Mina shouted, collecting a few things as Katsuki led you upstairs.

You sighed in relief as you entered familiar ground again. You followed the blonde until he stopped at an empty table, pulling out a chair, “Sit.” his eyes darted between you and the chair his hand rested on.

You immediately obeyed his order, sitting down. The chair was pushed towards the table seconds later. Katsuki sat across from you, “Ya’know, it’s polite to say thank you,” he spoke softly, surprising you, “and I never caught your name.” he mumbled.

“I’m sorry!” you squeaked, you didn't want to seem rude, “Thank you,” you managed the get the words out smoothly after a few seconds, “and It’s y/n,” you mumbled the last part.

“Y/n.” Bakugou repeated, liking the way your name sounded rolling off his tongue, “That suits you.” He smirked, leaning against the table.

The way he said your name had you clenching your thighs together impulsively, something about him just had you so flustered, he was so charming and naturally dominant that submissive instincts you didn't even know you had were coming out.

You glanced around the library, wondering when Mina was coming to join you. Much to your dismay, she was nowhere to be seen, it was bad enough that you were turned on, but it was worse that the subject of your thoughts was right in front of you. 

You shifted in your seat again, subconsciously trying to create friction between your thighs, you let out a soft sigh as you felt a bit of what you were searching for.

“You know,” Bakugou spoke, startling you, “I know exactly what you’re doing.” he stood to his feet, leaning over until he was at eye level with you, “Didn’t think I flustered you that much.” he let out a laugh and you felt yourself sink into your seat out of embarrassment.

Why had his antics gotten to you so much? You were never like this, you never did things this risky before. Katsuki had you acting completely different.

“I wasn't-” you gasped as he leaned closer, hot breath fanning across your face.

“You weren't rubbing your cute thighs together? You weren't thinking about me?” calloused fingers grasped your cheeks again, slightly squishing them between his fingers as he had done earlier, “I don't like lying brats very much,” he hummed, “I prefer good, obedient girls.”

You shivered at his words, squirming to break free from his grasp, you never let men touch you like this, but at the moment you didn't really mind. 

Just as Katsuki was about to speak he heard a door open, causing him to instinctively jump back, leaving you dumbfounded and nearly drooling.

Mina entered the room a few seconds later, sitting beside you at the table, “Sorry it took so long! Had to make some copies.” she handed the blonde some paperwork.

“This shouldn't take too long!” Mina assured you, sitting down beside you, completely oblivious to what has just happened between the two of you. 

You sat beside her completely flustered, trying to keep your eyes off Katsuki as the two of them went over next week's lesson plans.

After an hour had passed, you finally said your goodbyes and returned to your shared apartment with mina. As soon as you arrived, you let Mina know you were going to sleep and dashed to your room, locking the door behind you so you could take care of your little problem.

While you were alone in your room, knuckles deep in your cunt, Katsuki was across town in his own apartment fisting his cock to the thought of your cute little face and your sweet voice.

In his mind you were moaning his name like a virtue, begging him for more, more, more. He had never taken a liking to any of his students, but something about you was special, your timid personality forced out the dominance in him. He had such a strong urge to care for you, protect you, keep you safe.

His mind was racing with thoughts as he pumped his fist faster, precum leaking from his bright red tip. He wondered what your body looked like, what your soft skin would feel like under his calloused and worn hands, wondering how you would react to his touch. Had you ever even been touched before, or were you a virgin? The thought of him stuffing his cock into your virgin cunt, molding you to the shape of his cock was just too much for him. With a loud grunt and a final pump of his fist, he let go, white spraying across his abdomen and chest as he came the hardest he had in so long, and all to thoughts of his new, shy student. 

The next week’s lesson was pretty light, Katsuki talked about aftercare and its importance. You had trouble paying attention, you couldn’t stop thinking about last week when you were alone with him in the library, you wondered if he was thinking about kissing you. You hoped he felt the same as you did, but you wouldn’t dare ask him.

When the lesson came to an end, you found yourself feeling a bit sad, Katsuki had hardly paid you any mind the entire time, even when you were leaving with mina, he didn't bother to say goodbye. When you returned to your apartment, you immediately locked yourself in your room, needing some time to be alone with your thoughts. 

Why did you even like Katsuki? You hardly knew him. Sure, he was charming and handsome, but what type of person was he? What were his interests even? You realized you had a lot of unanswered questions and you were unsure if you would even know the answers to them.

Katsuki on the other hand, felt horrible for ignoring you all night, he wanted to talk to you, look at you, but he just couldn’t bring himself to do any of those things. He had never taken a liking to someone so quickly, especially not someone in one of his classes. Hell, he had even touched himself to the thought of you, what was wrong with him? 

He wanted to know more about you, but you seemed so innocent and fragile. He didn't want to hurt you or break you. You were so persistent in his mind that night, overtaking his every thought, what did you like to do in your free time? How did you take your coffee? How would you sound moaning his name? His mind was racing, but he knew he had to do something, he just wasn’t sure what.

By the third week, you were excited to tag along with Mina to class, you even asked her if you could go this week instead of her asking you. You were hopeful this week would be different and Katsuki would pay attention to you.

Mina was surprised to see you take an interest, but she was glad you wanted to spend more time out of the house.

When you arrived at the library and entered the basement, you immediately took the seat in the front row as you had the previous weeks. Luckily, this time you arrived early, so you didn't have to deal with as many awkward stares as before. 

Once everyone had settled in, Mina and Katsuki took their places in front of you and your fellow peers.

Bakugou started the class a normal, explaining what topics you'd be going over this week, “Today we will be learning about collaring and consent. I'll start simply by explaining consent and why it's important.”

Bakugou gave a rundown of why consent is important and how to react if consent is revoked in the middle of a scene, “A good system of safe words to use is the stoplight system, is anyone familiar with this concept?” a few students nodded and you gave Katsuki a confused look, “its a simple concept, Green means to continue, yellow means slow down or do less, and red means stop. If your partner says ‘red’, you should stop immediately and check in with them, offer them aftercare. We went over that last week.” he hummed as he finished his thought.

You listened closely as he spoke, trying to pay attention, but the way he was stealing glances at you made things rough, you resisted the urge to rub your thighs together, not wanting to get caught again.

“Now, this week I will need a helper, usually Pinky is my helper, but this isn't really her style,” he remarks, letting out a laugh. Mina smiles at the class and nods in agreement.

You wondered who Katsuki would choose to help him as he strode through the room. When he stopped in front of you, your heart dropped, “Care to assist me?” he hummed, turning his attention to you.

“Ah, I’m not sure,” you mumbled, peeking up at him through your lashes. You glanced over at Mina, begging her to help you, but all she did was shrug in response, “I’m not very experienced.” you trailed off.

“I think you’ll be perfect, don’t worry.”

After a minute of coaxing, Katsuki had you standing beside him in front of the class, you resisted the urge to cower behind him, not wanting to appear weak.

“Alright, We’re going to talk about collars now,” Katsuki’s voice boomed beside you as he reached over to grab a simple black collar from the table in front of him, “I’m sure some of you are familiar with these and what they signify,” He continued, rubbing his thumb over the leather band, “Collars are very important in BDSM relationships, they are similar to wedding bands. They signify love, trust, and devotion.” he glanced over at you, admiring the way you looked up at him in awe.

“Now, I am going to demonstrate for you all how to properly put on a collar like this.” He held the item in the air, “it’s a fairly common type of collar, so that’s why I chose this one.”

Katsuki turned his attention to you, “Sit for me, please.” He addressed you in a soft tone, but you still gave him a confused look. You weren’t sure where to sit, as there wasn’t a chair. After a moment of silence and you awkwardly standing in place, he spoke again, “Sit on the floor, tuck your legs underneath you.”

Your heart raced as you followed his command, even went a step further and rested your hands on your bare thighs as your skirt had ridden up slightly.

“Good girl.” He hummed, just loud enough for you to hear, “Now, once you’ve got your submissive in position, you want to ask her for consent.” He kneeled in front of you before speaking again. 

“What’s your color?” Vermillion eyes held an emotion you didn’t recognize, causing you to fluster.

“Gr-Green, sir.” You whispered your reply, too embarrassed to speak up.

Bakugou’s heart swelled with admiration as you used the simple honorific. He knew it didn’t mean you belonged to him, he knew you were just being respectful, but it made him feel something he wasn’t sure if he liked or not.

“Louder please, it’s important that you voice your consent clearly.” He spoke sweetly.

Many of the students were shocked by how calm Katsuki was behaving, they had never seen him so serene before. Many of the women in the class were quite jealous of you, they would do anything to be in your spot.

“Green.” You spoke up slightly, causing Bakugou to smile. 

“Good girl,” he addressed you quietly before speaking to the class again, “It’s very important to clearly state your consent, especially if your partner asks. This will avoid confusion and make things run smoothly. Please remember that it never ruins the moment to check in with your partner.”

His eyes were back on you again, “Relax for me,” he murmured, moving your hair out of the way to place the collar on your neck. “Now for collaring, when you are putting one on someone, you want to make sure it’s not too tight, be sure to check and make sure.” Calloused fingers looped the collar around your neck with ease, “Once you’ve got in on, slip two fingers between the leather,” he did as he said, fingers pressing softly against your skin, “If it’s too tight, you risk causing damage to someone’s windpipe.”

Once the collar was secured in place, he turned it towards the front of your neck and stood back to his feet, “Face them, please.” He addressed you without even looking down. 

You nearly pouted as your whole body flushed. You slowly turned to face your peers, a nervous look covering your face. You couldn’t seem to drag your eyes from the floor.

“What’s your color?” He asked again, this time looking down to meet your eyes. You wanted to say red, and get up and leave, but you didn’t. Part of you wanted to stay right where you were, you knew you didn’t belong to him, but at the moment things felt right. 

“Green.” You said softly, smiling at him.

“Good, we’re going to continue then, please tell me if anything changes.”

Bakugou continued talking about collars for a few more minutes. As time went on, you felt a bit more comfortable sitting on the floor beside him. Katsuki has even gone as far as petting your hair as he spoke.

“Now, we are going to talk a bit about leashes.” He grabbed a leash that matched the collar around your neck and you perked up. 

You couldn’t help but squirm as he spoke about the item, explaining the safety of how to use it, and how it tied in with certain types of relationships. 

He once again dropped to his knees in front of you, speaking quietly enough for only you to hear, “I’m going to attach this, okay?” He latched the leash onto the collar, grasping the end in his fist, “Can you walk around for me?” He spoke before standing up and you nodded softly. 

“Now, I’m going to take our little pet on a walk around the room, just to demonstrate how to properly handle a submissive while using a leash.” He spoke with authority, still holding the end of the lead in his fist firmly.

“Walk.” He commanded.

You glanced up at him for approval before you begin to follow him, crawling around on your hands and knees. Every few minutes Katsuki would check with you, making sure you were comfortable. 

Your peers seemed to think you were quite adorable, some of them commenting on how cute you looked crawling around. As you neared the back of the room, you almost felt confident alongside your teacher, no longer worried about the others in the room.

As Bakugou lead you back to the front of the room, one of the male students attempted to snatch the lead from Katsuki’s hand, causing you to be yanked towards one of the tables roughly, slightly choking you.

You let out a squeak and began to cough, “Red.” You uttered the single word and Bakugou was fuming, yanking your leash from the student's hand.

“Mina!” Bakugou barked from across the room, “Get them out, now. Everyone out!” He shouted angrily before coming down to meet you on the floor. 

Mina guided the other students out of the room, apologizing for the lesson having to end early. Once the room was empty, Katsuki spoke softly to you.

“Oh gosh, I’m so sorry that happened.” He was removing the collar and leash before you could say anything, hands softly soothing the skin at the nape of your neck as tears welled in your eyes, “Oh, don’t cry, it’s alright. It’s just you and me now.” He cooed, pulling you up to hold you against his chest.

You nuzzled your head against him without thinking, nearly sobbing into his shirt, “wanna go home.” You whined.

You felt so.. weird. You were in a headspace you were so unfamiliar with. You had never felt this way before, you felt so small, so dependent.

Katsuki knew exactly what was happening, you had dropped into subspace and some asshole had ruined the experience for you. He wanted to beat the shit out of that guy, but he trusted Mina to take care of it.

“Don’t worry, it’ll take care of you.” He assured you, “M’gonna take ya’home, make sure you’re safe.” He offered you a gentle smile, softly padding away your tears with his thumb.

Katsuki’s eyes scanned the room, searching for Mina, but she was still nowhere to be seen.

“Jus’take me home.” You whined, clinging to the blonde’s shirt with your tiny fists, “wanna lay down.” 

Katsuki groaned as he decided he couldn’t wait for Mina any longer, He didn’t want to startle you, or make you wait so he did what he needed to.

He quickly texted Mina, letting her know he was going to take you to his apartment with him because she was taking too long. Once he sent the message, he picked you up, wrapping your legs around his waist the best he could.

“Gonna take ya’ back to mine for tonight, alright?” He grumbled, carrying you to his car.

All you could do was nod into his chest, letting out a soft whine as he sat you in the front seat of his car.

You held your knees to your chest as you sat in the passenger seat, trying to make yourself as small as you felt inside. Everything felt so off. You felt scared, and you weren't even sure why. You knew you were safe with Katsuki, but all you could think about was getting yanked around and humiliated in front of people you hardly knew. You caught the glances of your peers as they left the room earlier, and some of them look pissed. You had ruined Bakugou’s class, it was all your fault.

You arrived at an apartment complex that reminded you of the one you lived in, but you knew it wasn't your home. Katsuki ushered you inside without a word, keeping close to you as he guided you. Once inside, he slipped his shoes off and helped you do the same.

“M’so fuckin’ sorry that happened,” he finally spoke, leading you towards the couch, “Should beat the shit out of that fucker.”

You were shocked to hear Katsuki use such harsh language, he seemed so calm in class, this was a side of him you weren't very familiar with.

“Are ya’ feelin’ any better, can I get ya’ anything?” He seemed so... awkward now. 

You shook your head softly, “I’m okay, thank you though.” you muttered out, not meeting his eyes, “Jus’ tired.” A yawn you couldn't hold in escaped your lips.

Katsuki thought for a moment before speaking, “I’ll let ya’ sleep in my bed, just don’t tell anyone I’m a softie, eh?” he teased.

“I…I couldn’t do that. I’ll just sleep here.” You motioned toward the couch, but the blonde wasn’t taking no for an answer.

“No way, that thing is fuckin’ uncomfortable. I’ll show you to the bedroom.” He grumbled.

You let out a sigh, accepting your defeat as he showed you to his room. It was rather bland, just a queen-size bed, a few nightstands, and a dresser. 

Once Katsuki had shown you where everything was, he headed towards the door, “Well, I think that’s everything. Ya’ should be good for the night, yeah?”

“Thank you again,” you flashed him a smile, “I’m sorry if I caused any trouble tonight, didn’t mean to,” you mumbled

Katsuki was quick to assure you that you hadn’t done anything wrong, that you did just as he asked and you went above his expectations of you. You tried your hardest to believe him, but something in the back of your mind told you he was just being polite. 

“Hey, Katsuki?” You said softly.

He turned on his heels, eyes trained on you, “Hm?”

“Could you stay with me?” You glanced down at the bed beside you, hoping he would stay with you, as childish as it sounded, you just didn’t want to be alone. 

“Thought ya’d never ask.” He teased, “Let me get changed, an’ I’ll find you something to wear.”

You watched as Katsuki disappeared into another room. When he returned he looked much more comfortable, clad in a pair of sweatpants and a loose-fitting tank top. He held a T-shirt in his hand.

“Don’t think I have any pants that would fit you,” Vermillion eyes lingered on your body for a second too long, “but I think this will cover everything.” He tossed you the shirt.

You gave him a look, holding the shirt in your hands, “Don’t worry, I won’t peek.” He playfully rolled his eyes, turning anyway from you. 

You quickly slipped off your previous outfit, replacing it with the comfortable Tee. 

“You can look now.” 

Katsuki turned to face you, completely flustered by how precious you looked wearing something that belonged to him. Of course, he was very good at masking his emotions, so to you, he looked completely fine, but his mind was racing. He wasn’t one to bring girls home with him. He didn’t like the emotional side of relationships, so he avoided letting people in to the best of his ability.

Without a word, he climbed into bed with you, burying the two of you beneath the black duvet. You rolled over to face the blonde, giving him a sleepy smile. He reached up, softly brushing his fingers through your hair. 

Your eyes fluttered close, you were finally able to relax. Even in the silence, you found comfort. There was no need for words, simple actions spoke for themselves. Katsuki continued to pet your hair, even went as far as running his thumb across the soft skin of your cheek.

After a few minutes passed, Katsuki even found himself relaxing, he couldn't take his eyes off you, you looked so peaceful. Your breath had slowed down and he was sure you were asleep. Katsuki slowly shifted closer, your face just inches away from him. He could feel puffs of your breath hitting his bare cheek as he continued running his fingers through your hair.

“Green,” you murmur gently, catching Katsuki by surprise. It took a second for his brain to catch up with the racing thoughts he had about you to even fully recognize what you had even said. Though, when he did, he quickly closed the gap between your faces and smashed against your lips with a greedy, passionate kiss. You clung to him in need, your lips moving together with his, letting him take the lead. He gently began to stroke his tongue against your bottom lip and you allowed him entry without a second thought. His tongue slid past your kiss-swollen lips and began exploring every inch of your mouth, reveling in the taste of you. 

Calloused fingers roamed your body, leaving goosebumps in their path. Your skin felt like it was on fire as his lips trailed from yours down to your neck, softly sucking at the nape of your neck. You couldn't help but let out a wanton moan, everything felt like heaven, you couldn't get enough of his touch.

Katsuki let out a groan against your skin just before he pulled away, “Fuck, I marked you. I’m sorry.” He examined the red mark on your neck, watching as it was fading to purple. 

“More, please.” You whined.

“Fuck baby,” His hands trailed down your body, stopping at your plush thighs, “Are you sure?” his eyes met yours.

You nodded fervently, “Please, I need you.” You urged, placing your smaller hands on top of his, moving them closer to the place you needed him the most, “Touch me.”

He could feel the patch of slick on the thin material covering your cunt. Bakugou softly tugged down your underwear, exposing you. Fingers slowly inched towards your clit, causing you to whine. You had never been touched like this before, your body was so reactive and he just couldn't get enough.

“Relax f’me,” He let out a breathless grunt, “Gonna touch you more, okay?” His fingers returned to your bundle of nerves, rubbing small circles on the nub until you were keening. Your tiny whimpers only egged Katsuki on, he sped his action, causing you to moan louder.

“Ah, Please Kats!” You squirmed against his hold, hoping to gain more friction, “More, More, More, please!” 

You felt so drunk on his touch, you just couldn't get enough of him. Everything felt so right, you would let this man do anything to you.

Bakugou pressed your hips down into the mattress, holding you down with one arm. His fingers left your clit, causing you to whine at the loss of contact, “Color?”

“Green.” you huffed out, a hint of annoyance in your voice.

Katsuki narrowed his eyes at you, “Don’t give me an attitude, I’m not done with you.” He nearly growled.

You straighten up immediately, not wanting to upset him. 

“Behave, or I won’t make you cum.” he taunted, flashing you a smirk as his fingers returned to your aching cunt.

“Yes sir!” you gasped out as one long finger entered you.

“Good girl.” he mused, slowly pumping his finger in and out at a tantalizing pace. He wanted to go faster, harder, even make you cry, but he knew he needed to be slow with you. You trusted him to take care of you, and he didn't want to ruin that. As your moans for him grew louder, he was slowly losing what bit of restraint he had left.

Katsuki slipped in another finger, stretching you out slightly, “Ah, Oh my god.” You whined, head lolling to the side as you approached your climax. Katsuki glanced down to watch you take his fingers, Your arousal was already coating his palm.

“Please, don’t stop, wan’ cum.” You slurred out, eyebrows knitting together.

“Not yet, baby. Your moans are so pretty. You can last a little longer, can’t you?” he teased, curling his fingers to press against the spongy part inside of you.

You let out a loud moan as he continued pressing his fingers against that spot inside of you, drawing you closer to the edge, “Please! Katsu, Please!” You whined, bucking your hips to meet his hand, chasing your high.

“You wanna cum baby? Wanna cum for me?” Katsuki taunted, quickening his pace.

“Mhm!” you nodded, “Please! Wan’ cum for you!” you moaned, taking your bottom lip between your teeth.

Fingers curled one last time before you let go, your arousal coating his hand and forearm. Your vision faded as you reached your climax, feeling like you were on cloud nine.

Praise rang in your ears as Katsuki talked you down, slowly bringing you back to reality. Letting out a huff, you finally caught your breath.

“You did so well, such a good girl.” Katsuki praised, slowly pulling his fingers from your drooling core, “Look at that.” He held his hand up, showing you how your arousal glistened on his hand. He drew his fingers passed his lips, sucking off your juices.

He pulled them from his mouth with a soft ‘pop’, you leaned in to kiss him, tasting yourself on his lips. Katsuki nearly let out a moan against your lips, everything about you was so perfect.
