Quirk: Shadow Manipulation

Requested by: IcyThot_is_Mine

 Katsuki and I were next door neighbours, so we had grown up together and became close personal friends. I was the only one who control his behaviour and tell him off, and he had come to appreciate me as I did him. He was like a brother to me, he treated me like a sister, and was always very protective over me, particularly when it came to boys. Very few even dared flirt with me during middle school in fear of having their heads blown off, and I had to talk to him a few times about me being able to handle myself.

We were naturally excited when we got into UA, and thankfully Katsuki's brutal behaviour began to calm down without the need of me. He finally realised that there were people out there just as strong as him. One of those people was Shoto Todoroki, and I had to admit that the first time I saw him, despite him being unsociable, I couldn't help but find him attractive. He was definitely the most attractive in the class, and I was yet to see someone in the school who was better looking than him. All of the girls in the class agreed with me, and I couldn't help but fall for him as he began to open up and start to make friends.

Unfortunately for me, Katsuki seemed to hate Todoroki which was highly inconvenient for me. Todoroki and I talked a lot in class and in the common room of our dorm building, yet whenever Katsuki saw this his protective mode turned on and he'd either drag me away elsewhere or sit in between us, telling Todoroki to get lost. I'd always ended up apologising to Todoroki later on about Katsuki's behaviour when the latter wasn't around.

"No need to apologise, I guess boyfriends can be like that," he shrugged, looking at the floor and I felt my cheeks heat up.

"Katsuki's not my boyfriend!" I exclaimed quickly, desperate to tell him that that wasn't the case.

"He's not?" He looked up at me and I shook my head.

"No! He's more like a brother to me, that's why he gets so protective..." I mumbled. "I am sorry about him," I pouted, thinking about my irritating best friend who I did love, but in a platonic way. There was a slight pause between us, until he said something that made my jaw drop.

"If you're not in a relationship with him, then will you be my girlfriend?" He asked. I thought my heart had stopped as I simply stared at the most handsome guy in school, trying to register the fact that he had asked me to be his girlfriend. "Er... (y/n)?"

"Y-yes- yes!" I exclaimed, perhaps a little too excitedly.

"I'm glad," he said with a sweet smile that melted my heart.

"Me too," I assured him, my heart doing back flips.

I was sat in Shoto's room, currently hiding from my best friend, having told him I had gone on a walk to clear my head. He tried to insist that he came with me but I managed to convince him to stay at Heights Alliance, and instead of leaving towards town I creeped around the back of the building, Shoto sending me down a tower of ice for me to climb, then melting it once I had reached his room. The two of us were cuddling on his futon he had left out, soaking in the bliss of being in each others arms. I was still having difficulty comprehending the fact he was now my boyfriend and that I was currently cuddling up against him, but I was so happy that I would change a thing.

"(y/n), I don't like this," Shoto suddenly said, and my insides went ice cold with fear. "I don't like having to keep us a secret."

I let out a sigh of relief, thanking god that he wasn't about to break up with me. "I know, but you know how he is, he'd probably fight you if he found out about us," I said, my fingertips drawing shapes on his chest.

"So? I'd obviously beat him," Shoto said and I chuckled.

"I know you're not his biggest fan Shoto but he's my best friend and has been since I was young. I know he can be a little... difficult to handle," I admitted.

"He used to bully my best friend (y/n)," Shoto's tone was turning stern, and the last thing I wanted to do was fight this early in our relationship.

"I know and trust me, I stopped him whenever I saw him doing so," I insisted, looking up into his heterochromatic eyes pleadingly and he sighed.

"I imagine you did," he said softly, leaning in and pressing his lips against mine making me smile. "He'll find out eventually though (y/n)."

"I know he will, and I'm seriously trying to think of the best way to tell him. I think it'd be better for us to tell him rather than him find out from a third party," I said and he nodded in agreement, pulling me in for another kiss that slowly got more and more heated until it turned into something very passionate.

- Timeskip -

Shoto and I had been together for three months at this point, and our relationship was still a secret. He understood why, but it was beginning to really get him down that he couldn't hold my hand or kiss me in public like I could tell he wanted to. I wanted that too, but I was still scared at what Katsuki's reaction would be and I was now desperately trying to figure out ways in which to tell him without seriously angering him.

It was getting increasingly difficult to figure out ways in which Shoto and I could tell him, thanks to the class who, despite not knowing that we were a couple already, always liked to state that Shoto and I would look good together. Whenever anyone in the class teased the two of us saying we should get together, Katsuki would burst into the conversation and take ahold of my hand roughly. Whenever he did this I glanced at Shoto who always had his nose scrunched in anger, but I sent him a reassuring look. "Don't ever 'ship' her with that icy-hot bastard," Katsuki would scowl at those who were saying Shoto and I would make a good couple, and this angered Shoto even more. I knew I had to get our relationship out into the open soon, very soon, before Shoto became seriously angry.

My boyfriend and I were currently in my room, me sat in between his open legs in front of my low table, finishing off some homework, his arms wrapped tightly around me and his head rested on my shoulder. He was so obviously deep in thought as he was quieter than he usually was, and I finally dared to ask him what was wrong. "He has a crush on you, doesn't he?" Shoto mumbled, digging his head into my neck. I knew immediately that the 'he' was Katsuki, and I couldn't help but let out a laugh, catching Shoto's attention.

"Of course he doesn't Shoto," I laughed, glancing over my shoulder and seeing his head raised and his eyebrows furrowed.

"Then why does he always grab your hand? Why is he always so protective over you?" He asked.

"Because I'm like a sister to him," I said but Shoto wasn't convinced and I sighed. "Shoto, Katsuki doesn't have a crush on me."

"How do you know that?" He asked and I laughed again.

"Three reasons. One, he sees me as a sister," I held up one finger. "Two, he's gay," I held up another finger, ignoring Shoto's shocked expression, "and three, he has a huge crush on Kirishima," I held up a third finger. An embarrassed blush came to Shoto's cheeks, making him look even cuter.

"S-sorry (y/n), I shouldn't of made assumptions," he murmured but I shook my head and pecked his lips.

"It's okay Shoto, although I'd really appreciate it if you didn't tell anyone that he's gay or has a crush on Kirishima... he hasn't come out yet, well only to me, and he's nervous to," I said and he smiled.

"I promise I won't tell," he said and I smiled, leaning in a kissing him sweetly. The kiss soon turned passionate, as he turned my body a little and cupped my cheek. Our mouths slowly opened and our tongues brushed against each others delicately at first, however the kiss soon turned rough. Shoto and I had recently been intimate for the first time, and since then we could barely get enough of each other. I was easily distracted from my homework, and turned around, pinning him to the floor and straddling his waist, making him smirk.

I laid my body on top of his, his arms wrapped firmly around my waist apparently refusing to let go of me. We pulled our lips apart for a few seconds to catch our breaths, but soon enough we were back together again and kissing hungrily. I started to tease him by grinding against his crotch, his member slowly awakening. His moans against my lips boosted my confidence but I scrambled off of him and jumped onto my bed, wanting to do it on a more comfortable surface rather than the hard floor.

He was immediately on top of me, his head delved into my neck and his lips sucking at my skin, moans spilling from my mouth. He brought his hands up to my chest, cupping my still clothed breast as he continued to suck at my skin. "S-Shoto- you can't leave marks!" I breathed and he pulled his head away.

"Too late," he bit my ear making me yelp, and I felt heat begin to pool in my core. He was taking charge like he always did, and his hands worked their way to my school shirt; I had taken my blazer and tie off earlier, so he just had to deal with the shirt. With each new patch of skin that showed, he pressed his lips against it, teasing me with his gentle kisses which went further and further down my body. It felt blissful, and my eyes fluttered closed to make it feel more exciting, not knowing where his hands or fingertips would trail to next, especially once my shirt was fully unbuttoned.

I let out a gasp and raised my chest slightly as his lips pressed against my cleavage, whilst his fingers wrote the word 'sexy' on my stomach. I bit my lip at his amazing intimacy, admittedly surprised at how passionate and sexy he could be in the sheets. During our first time he was nervous, but so was I, however it didn't take long for the two of us to get used to each others bodies so much so that it now seemed as though we knew each other like the back of each others hands.

"Shoto," I whined, adoring his touch. He knew exactly where to go to turn me on, although it was impossible not to get turned on when it was Shoto Todoroki touching you. He smirked against my skin, bringing one hand behind my back and unclasping my bra. I was surprised at how he had become a pro at unhooking my bra so easily, especially as he couldn't do it the first couple of times, but we had had plenty of sex since so I guess it was a case of practice making perfect.

"Your skin feels so good," he whispered in his husky, turned on voice. I smirked in satisfaction, adoring the compliments he dealt me whilst we were intimate. He made me feel so good, and boosted my confidence with each item of clothing lost. He pushed my bra up, unable to actually pull it from my body as I still had my shirt on, and I couldn't help but gasp loudly at the unexpected feeling of his lips against my breasts so early. He'd usually spend a while massaging them first, but he seemed pretty eager so got straight down to it.

"S-Shoto-," I adored whining his name and he seemed to love it too as it always spurred him on.

"Your boobs are so addictive," he breathed quickly, before planting his lips back on one, sucking and flicking his tongue back and forth against my hardened nipple. Once again I moaned out his name, his attention going to my other boob. I gripped the bedsheets, his skilled tongue licking at my breast amazingly, his hand coming up and massaging my other breast fairly roughly. I opened my eyes to watch him work, the sight being gorgeous and one I carved desperately into my brain.

I began breathing heavily, but knew this was only the beginning of the immense pleasure Shoto was about to deal me. His lips travelled back up to my neck, then onto my lips whilst both hands massaged my breasts. He straddled my waist and I could feel his large erection against me. "Mm, Shoto, please," I whispered huskily as our lips ghosted each others and he smirked.

"Don't worry, I'll give you it all," he whispered, then sitting up and unbuttoning his own top. I had learnt that as much as he adored us both being naked, he found it incredibly hot when the two of us were just wearing our shirts. Because if this factor he pulled me up, pulled my shirt off followed by my bra, discarding the latter and slipping my shirt back on. I smirked at this, as I had also fallen in love with partially clothed sex.

He pushed me down to my bed and unbuttoned his trousers, pulling out his erect member from the flaps in his boxers. I bit my lip eagerly as soon as he had it pulled out, and I knew my boyfriend well enough to know what was coming next.

He crawled up my body, his member right in front of my mouth. "Open up," those two words, plus his grip on my hair was enough to tell me that he was eager to face-fuck me, something which I happily let him do. My core was heating up immensely at this point, especially when as soon as I opened my mouth, he had his dick shoved down my throat.

I almost choked on his seven inch straight away, but he soon started thrusting and pulling my hair. I had to grip his firm bum, something which he loved me doing each time he face-fucked me. I rubbed my thighs together in an effort to relieve some of the heat that was growing down below but it was difficult. I was already so eager to have him, but I knew how much he loved foreplay.

He kept on thrusting, my saliva dripping from my mouth. "Fuck- (y/n), it's so good- as always," he moaned, stroking my cheek but never letting up his pace. One thing that surprised me about him was how much he actually swore, but I admittedly found it quite sexy, especially in situations like this. "Mm fuck, yeah keep going like that, your slutty mouth is so good."

I almost choked as he sped up, his head tilting backwards and the indecipherable moans escaping his mouth was enough to tell me he was close to ejaculation. I prepared myself for his salty liquid to be released into my mouth, and a few seconds later it was. His grip on my hair tightened as he let out a long moan of my name, boosting my confidence knowing he wasn't thinking about anything or anyone else other than me.

He pulled his now limp dick from my mouth as I swallowed his salty liquid, wincing a little like I did every time, and just like every time he worriedly asked if I was okay, to which I nodded assuringly. "That felt so good babe," he praised and I smirked proudly. "Now it's your turn."

"Y-yes please, Shoto I want you so bad," I whined, my thighs still rubbing against each other.

"Well now, you do seem eager," he teased me, unzipping my skirt and pulling it down, followed by my underwear. "You're soaked (y/n), you look more desperate than usual."

"D-don't say such things," I whined, embarrassed but knowing it was true. Like my bra, he threw my skirt and panties to the floor but kept my thigh high socks on, not that I was surprised. He carefully opened my legs up, my soaked core being properly revealed to him.

"Holy crap, you really are soaked," he almost chuckled, and I hid my face behind my hands out of utter embarrassment. "You're so hot," he whispered, pulling my hands from my face. "I want to see your face when I make you cum."

I let out a loud squeal when two of his cold fingers entered me easily. They went in as deep as they could go, and each time he thrusted them, the squelching sound of my wet womanhood could be heard, utterly embarrassing me. He was staring at my pleasure filled face as he continued to thrust his fingers, satisfied with the way his skilled fingering made me clutch onto the bedsheets. It was amazing how quickly he had managed to pick up such skills as this, considering I was his first when it came to anything remotely sexual, and we had only been together for three months, being intimate for the first time only a month ago. "S-Sho- Shoto-,"

"You're feeling good?" He teased, nibbling at my air, his hot breath sending chills down my spine.

"So good!" I moaned, my legs twitching as I could feel myself getting closer to my first orgasm. He suddenly pulled his fingers out however, much to my irritation. He laughed when I pouted, then bringing his fingers up to his lips and licking them clean. My cheeks heated up out of embarrassment, and I looked away from his handsome features.

"Aw baby, don't be embarrassed," he whispered, nibbling at my ear again. "I don't want you to cum unless it's against my mouth or dick," he added, going down on me. I watched him in anticipation, letting a loud moan escape my mouth as he latched his lips onto my pussy, using his tongue to pleasure me immensely. He lapped away at my wet core, his nose brushing up against my clit whilst his tongue focussed on entering my hole. My heavy panting told him how much I was enjoying this, and with one hand I gripped onto his hair, the other gripping onto the bedsheets tightly.

"I-it feels so good- Shoto! It feels so good- so good-," I whined, breathing heavily as he continued his movements. My body was getting closer and closer to my first orgasm of the night, and once he brought his wet finger up to brush against my very sensitive clit, I couldn't help but cum all over his face, throwing my head back in pleasure.

Shoto didn't stop however, no matter how many times I told him I was feeling over-sensitive. He knew how much I loved over-stimulation, the strong feeling of it and the way my body twitched thanks to it. He had to grip onto my waist to stop me from moving about to much as he continued to lap up the cum that released from my womanhood. "You taste so good (y/n)," he whispered in his husky voice, wiping his lips with the back of his hand before sitting up with his legs outstretched. "Straddle me," he commanded and I nodded weakly, desperate to feel his hard again dick inside of me.

I did as I was told, wrapping my arms around his shoulders as he wrapped his around my waist. My knees were either side of his waist, and he slowly lowered me down, his dick entering without any lube needed thanks to my natural wetness. We both groaned, and I adored the feeling of him inside of me - it was like a drug.

"Mm, (y/n), you really are so wet today," he groaned, our faces close.

"I-it's because of you," I whispered and he smirked in satisfaction.

"I'll happily take the blame," he said, before he began moving me up and down. I let out a loud moan as he bounced me up and down on his rock hard seven inch, my grip on his shirt being incredibly tight. "Fuck- (y/n), you're feeling so good," he growled as he continued to thrust upwards, using the strength in his arms to help move me. I was like a ragdoll, I was complete putty in his arms as his dick made me feel high on desire. There were no distinguishable words coming from my mouth as his member hit my g-spot repeatedly, edging me closer and closer to my orgasm. I could feel it coming and I knew it was going to be incredibly strong.

"C-cum- in-inside- Shoto," my sentence came out as slurs but he understood what I meant. As soon as we had had sex the first time I went on the pill so that I could feel his cum seep into me with a very low chance of getting pregnant. "Please!"

"Fuck- (y/n), keep groaning like that and I won't be able to hold back," he growled in his sexy tone. I was moaning out his name on repeat, him being the only thing I could think of, his dick pounding into my pussy and completely abusing it. "So wet," he acknowledged, sexy grunts escaping his mouth also. He continued to bounce me up and down, my womanhood tightening as I reached my orgasm.

I cried out louder than I should've, but it was nothing short of incredible. My womanhood tightened around his member as I gripped onto his shirt tightly, throwing my head back, my whole body twitching. "I'm gonna cum- (y/n), (y/n)!" He cried out my name as I felt him shoot his hot cum deep within my pussy.

The two of us sat there for a moment, with his half-hard dick still wedged in my womanhood, cum slowly dribbling from it and onto his lap. We were both desperately trying to catch our breath after round one, our sweaty bodies sticking together slightly as we lazily looked at each other, high on the others sex drive. Our lips met in a lazy and sloppy kiss, however we heard a sound that gave us both a heart attack.

The door to my dorm room opened, and a voice sounded, one we did not want to hear. "(y/n), where the fuck- WHAT THE FUCK?!?" Katsuki's voice reverberated around the room as Shoto and I turned to see him started there, red with anger and embarrassment, explosions emitting from his palms.

"K-Katsuki!" I exclaimed, clambering off of Shoto and reaching for absolutely anything to cover me and my boyfriends practically naked bodies. I had managed to grab a blanket that was near my bed and immediately threw it over the pair of us, buttoning my shirt up quickly but Shoto was just glaring at my best friend as though daring him to do anything.

"ICY-HOT WHAT THE FUCK DO YOU THINK YOU'RE DOING TO MY BEST FRIEND?!" Katsuki screamed loudly.

"I was having sex with my girlfriend," Shoto retaliated simply, Katsuki's anger levels rising.

"S-Shoto-,"

"FUCK OFF! As if she'd go out with someone like you!" Katsuki screamed. "You stay the fuck away from her!" Katsuki went to grab my hand but Shoto stopped him.

"She can pick whoever she wants to date, plus she loves me and I love her, you can't control her life-,"

"SHUT UP YOUR BASTARD! She deserves way better than you!" Katsuki screamed.

"SHUT UP!" I shouted loudly, standing up, having reached for my underwear and slipping it on whilst the two boys fought verbally. I quickly approached Katsuki and held onto his arm desperately trying to catch his eyes. "Look Katsuki, I'm sorry you had to find out this way, I've been trying to think of a way to tell you for ages-,"

"What do you mean 'for ages'?!"

"She means we've been dating for three months behind your back," Shoto said nonchalantly.

"Shoto you're really not helping!" I shouted at my boyfriend who just shrugged. "Look Katsuki, Shoto was right, I love him and he loves me, I'm so so sorry you had to find out this way. I didn't know how to tell you, I was trying to figure out a way without making you angry- please Katsuki, I'm happy with him, so happy, can't you be happy for me? Can't you be pleased that I've found someone I love?"

"Why the fuck did it have to be him?!" He shouted, his attention focussing on me instead of my boyfriend.

"Because I'm meant for her, that's why," Shoto said.

"SHUT UP YOU ICY-HOT BASTARD-,"

"Both of you just- just stop, please! Look, Shoto, Katsuki is my best friend and naturally he's protective over me, but Katsuki you need to acknowledge that Shoto is my boyfriend, and that I love him... please just- just be happy for me," I begged him, tears in my eyes. He was staring at me, still red with anger but the explosions emitting from his palms had died down. He sighed deeply, then glared at Shoto ruthlessly.

"I swear to god scarface, if you do absolutely anything to hurt her in any damn way, I will hunt you down and fucking kill you, you got that?!" Katsuki shouted through gritted teeth and I sighed, knowing that was the best I was going to get form the angry boy. Shoto's eyes were squinted and his teeth were clenched, and I knew that if his lower half was currently only covered by the blanket, he would grabbed Katsuki by the collar and probably spat out some insult.

"Of course I'm not going to hurt her," he growled in a threateningly low voice. Both boys glared at each other, clearly irritated.

"Don't you ever cancel our study sessions ever again just to be with this bastard," Katsuki turned to me, and I rolled my eyes, already used to his seemingly threatening sounding demands which were really just empty.

"How dare you tell her what to do-," Shoto started but I held my hand out, stopping him from saying anything else.

"And don't you EVER let me walk in on anything like... that ever again," Katsuki hissed and I sighed again.

"Sure," I said simply. He glanced at me with a somewhat apologetic expression. He pulled me into a hug, one I returned happily.

"If this idiot does anything to you-,"

"He won't-,"

"But if he does, you tell me straight away, got it?" He spoke as though Shoto wasn't in the room.

"Fine," I assured my best friend who, with one last glare, left Shoto and I alone.

"You really think I'd do something to hurt you?" He asked, a trace of insult in his tone.

"Of course I don't, I only said that to appease him," I said, making my way back to Shoto, the two of us laying down on the bed together, under the blanket. "I had completely forgotten about the study session I'd organised with him," I laughed awkwardly.

"Eh, what we were doing was more fun anyway," he smirked, kissing my forehead.

"Shoto?"

"Hm?"

"Katsuki is my best friend. I know you don't like him but please just- just try to keep the irritating him at a low level... please," I said, looking up at him and he sighed.

"For you? Sure," he said with a smile that I happily reciprocated. Thanks to the events of the last twenty minutes, it didn't take us long to fall asleep in each others arms, satisfied that we could now tell everyone about our relationship.
