Katsuki didn't know what to do when he got a frantic call from his best friend y/n
about needing an escape from a bad date. He hated it when she went on dates considering he's been trying to court her everyday since 8th grade of middle school and it's now senior year of collage. He could hear panic in her voice, so he quickly jumped up and got pants and a hoodie on, grabbing his keys. "Hey, stay where you are at and I'll come get you." He said to her as he heard her whimper out okay.

By the time he was dressed he was halfway out the door. He got into his car and drove to the place she was at. Of course it was a locally run restaurant. He got out and walked into the restaurant but was smack hard in the face with the stench of an omega in heat, he paled at the thought of it being her. He rushes towards the bathroom, he knocks on the door quickly, wanting to know if she was alright. "Come in 'Suki." He heard the scared timid voice of his childhood best friend's sister. He walked in and smelt her even more clearly now, it was making his alpha wanna claim her, to mate her. He shook his head and pulled her up from her sitting position with her knees pulled up to her chest and had her head buried in them.

"'Suki! What are you doing, you don't need to manhandle me!" y/n said and let him pull her up anyway knowing she had asked for his help. What she didn't expect was to be scented by him rubbing himself against her cheek and both arms. "I'm not manhandling you." He said and put his jacket on her to keep more of his scent on her.

"I'm making sure no one will touch you. As your friend it's my job to protect you." He simply said and his alpha was purring at the thought of her being covered in his scent. But that disappeared when y/n shrugged off the jacket he had put on her, causing him to growled but took the jacket back and sighs softly. "I don't need to be scented to be safe with you here 'Suki." She said, causing him to pin her against the wall outside of the bathroom. "You'll listen to me closely, I do because you're in heat so you know you're not safe without scent patches or representations." He snapped at her.

y/n shrinks slightly and bites her lip to not give in to her omega who wants to please him, but she was stubborn so she bared her teeth at him which made him growled and stare down at her when she didn't back down. So putting his jacket back on, he threw her over his shoulders, thankful she was wearing skinny jeans. He walked out to his car and placed her in the front seat, he buckled her in but not before she bit his hand, growling and hissing at him.

"I don't need a babysitter!" She snapped at him once more, he growled and got into the driver side and drove off. He bites his tongue to make sure he didn't stop somewhere random and fuck her stupid right there and then. "Obviously you do, you called me to pick you up to save you from creep! I told you he was just wanting a omega to fuck and you were that omega."  Bakugou said and pulled into the dorm garage. He got out and picked her up bridal style, carrying her to her bedroom all the while trying not to mate her. He wants to do this right, court her with gifts, scent blankets and hoodies and flowers. All that to have her as his mate, but smelling her in heat was kicking up his rut earlier then it supposed to be.

He drops her on the bed and prepares to go get her food when she grabs him, he looks down at her with a curious lift of his brow. "Please, stay." She said the words that were in his head every time he had to go get her. "I can't deal with fuck up thing alone Katsuki." She said and he growled, turning around and forced her to look at him. "First thing first, it's alpha if I'm going to help." He hissed out as she began to rub at his crotch, he swatted her hand away, smirking to himself. "You're not allowed to touch, if you do you'll get ten spankings, and you should do as you're told." He said, causing her to whine but nodded her head. "Good omega, now, take off your clothes slut, let me see your beautiful body." He commanded which she automatically listened to as she undressed herself, showing off her curves and the one thing he wanted to taste right now, her beautiful pussy.

"Be a good girl and spread your legs widely." He said but y/n smirked and closed her legs, not letting him see her cute little pussy. He growled and kneel on the bed. "Open your legs... now." Bakugou growled out causing her to whimper and kept her legs close to see what he'll do. But the gasped let out from her pretty red stain lipstick caused him to smirk when he had her bind over his leg. "Now count to ten then I'll reward you." With every strike against her ass, she counted each one but tears were beginning together in her eyes as the strikes got harder, leaving both cheeks red and sore. "Ten!" She cried out as he struck her left cheek once more.

He let her get back on the bed, but spread her legs this time. He looked at how it glistened in the moonlight, he laid down on his stomach so he could have a closer look at her quivering hole. He leaned in and ran his tongue up from her hole to her clit, moaning at the taste, he attached his lips to her clit, sucking on it before circling two fingers around her entrance. He moved away when he heard her cry out for more. "Patient, I'll give you more." He replied as he attached his mouth back on her, sucking and nipping at her clit, letting his two fingers enter her and began to pump them in and out. He could feel her walls clenched around his fingers making him harder so he began to grind against the mattress, her hand in his hair as she tried to stay in the present of our bliss.

"Alpha! More please?" She cries out as he sped up his fingers, hitting the perfect spongy spot in her causing her to see stars, her walls squeezing his fingers tighter, he pulled his fingers away as she cried out in disappointment but gasped in delight as he cover her pussy with his mouth and using his tongue to prod to at her entrance before he slip it in, a finger on her clit rubbing in time with his tongue thrusting in her leaking hole. "Alpha I'm going to cum!" She cries out and he sped up his rubbing at her clit, licking at her entrance once she started to come undone on his tongue and fingers.

After a few minutes he pulled away noticing she was becoming overstimulated, he got off of the bed and got undressed his cock slapped his lower abdomen. "Now since you've been a good girl, I'll give you a reward." He said with a soft smile as he placed her legs over his shoulders and lined himself up with her. "Are you ready?" He asked, making y/n nod her head. "Yes, Alpha, I'm ready." That's all he needed to hear as he slid in until he bottomed out, grunting how tight she was. "Fuck, so tight for me princess." He growled out, pulling out until the tip of his head was in. Before she could whine, he slams back in, grunting as he does so. "Fuck, alpha, feels so good." She whines and he begins a slow but steady pace, gripping her hips tightly.

"Fuck so good love." He praised as he kept thrusting in and out of her, rubbing at her clit, feeling her walls trying to suck him in deeper he folded her in half and began to pound into her. "Alpha! I'm gonna cum!" She cried out again before he stopped ripping her out of another orgasm. "Why? I was good! I was really good!" She felt tears in her eyelashes. "You're not allowed to cum until I say so." He said and thrust into her again, but a very slow pace was set, the thumb on her clit rubbing slow figure eights on it. He could feel her walls sucking him back in and he could get used to it. He quickly bends to her neck and bites harshly on her scent gland, marking her his forever, his omega no matter what.

He sucks on the bite as he feels her walls quiver around him, her scent turning into the smell of them both, turning him on more than he thought it would, knowing this he wasn't going to last long, so he begin to thrusts sloppily and rub her clit in sloppy fashion, cause her to cry out loudly. He growled and bites on her shoulder harshly to stop his, as he did so he could feel her tighten up. "I'm gonna cum!" She screamed out and with one last thrust he felt her come undone alongside of him, his knot swell inside of her. Connect them together for at least an hour until the swelling goes down. "I love you Alpha." y/n  said, causing Bakugou to smile the rare smile reserved just for her. "I love you too omega." He said as they both fell asleep for a nap.
