Hope this isn't so rushed

I sighed as I ran a hand through my hair as I entered the school gates. I was immediately greeted with stares and maybe some whispers. I groaned as I mentally slapped myself as I forgot to take my scent blockers.

In our school, alphas were praised as like trophies since everyone wanted to be marked by them so badly. I made my way towards my shoe locker and quickly changed my shoes until a hand made its way towards my shoulder.

I quickly turned around and pinned the other person against the locker and held their arm behind them. "Ow owie! (Y/n) it's mee!" Oikawa cried out in pain as I sighed and let him go. He winced in pain as he held on to his arm with fake tears.

"You're so mean!" He whined as he looked at me with a glare and stuck out his tongue. I was about to apologize but a strong scent of candy penetrated my nose. I quickly covered my nose and looked around. "Who the fuck smells like sweet candy?" I sighed angrily as my alpha instincts almost kicked in.

Oikawa laughed as he pulled himself together and got closer to me. He poked my chest and winked up at me. "I forgot to take my blockers today oopsie!" He said full with carefreeness.

"Why would you do that? Now people are going to go after you!" I said angrily as I dropped my hand and resisted against his smell. "Well let them~" he said with a smirk as he began to walk away.

"Hey!" I yelled obviously mad as I closed my locker and hurriedly went after him. "Dude that's dangerous. They can do a lot of bad things to you" I said protectively. Oikawa has told me in the past that he was so desperate to find a mate and to get marked but I didn't know he would go this far. I was worried that they might even take advantage of him.

"Why do you car-?" He began to ask until a strong hand wrapped itself against his wrist and pulled him hard towards the unknown person. It was a kid I've never seen before, he was tall but not taller than me.

"Hey wanna be my mate? I'm an alpha" the male whispered into oikawa's ear and oikawa started to look around nervously. "I-oh! But let's go out on a date first-!" He insisted but the male pulled him even more closer to him as he took a long whiff of oikawa.

"Nah let's skip that whole step so come with me" he said as he began to take oikawa away. I angrily clenched my fists and stepped up to the man and grabbed the males hand from oikawas wrist and pulled it apart.

"Hey let go of him" I said with frustration as I pulled oikawa towards me. He placed his head on my chest with both of his hands holding onto my forearms for support. "Who the fuck are you?!" The guy yelled as he felt like his "possession" was taken away.

"None of your business so leave us alone" I said again sighing as I waited for the man to leave. I was growing impatient as I looked at the clock in the hallway as we had only a few minutes until first period started.

"Wanna fight huh for this little slu-?!" The man angrily snarled at oikawa but I didn't let him finish that sentence. I shot him a menacing look as I opened my jaw and my sharp canine were visible. I never showed them to anyone because it mostly scares them away.

The man yelled in fear as he stared at my teeth and scrambled to run away from us. "(Y-y/n)?" Oikawa asked as he looked up at me. I quickly closed my mouth and waited for my teeth to retreat and go back to normal length.

"I didn't know alphas had really sharp teeth?! Let me see!" He pried as he got on his tippy toes and started to touch my face but mostly tried to pry open my mouth. I sighed as I pushed his hands away.

"Here I'll show you but take these" I said as I gave him a dosage of scent blockers and I took out some for me and took them without water since I like them like that better. "Okay okay but come over here!" He said as he pulled on my sleeve as we came across the water fountain.

He took the pills and took sips of the water. His scent began to disappear and to be quite honest, I was going to miss it. It smelled really good for a guy like oikawa.

"Awee~ your smell left!" He whined as he groaned but then got excited again. I sighed as I looked around to see if anyone was around but there wasn't. "This is the only time I'm going to okay?" I told him and he nodded furiously not even listening to what I even said.

I closed my eyes and started to think of bad thoughts. I normally would think about my past but this time thoughts of oikawa getting hurt by various alphas crossed my mind and my teeth grew in size then they have ever before. "Woah can I touch them?!" He asked as he got closer and looked at them as if they were a huge deal.

I blushed lightly and nodded. His hand was brought up and he lightly touched them. He winced lightly at how sharp they were from the point on the bottom. I closed my mouth temporarily waiting for them to retreat and opened my mouth back again.

"Scary right?" I said as I straightened myself up and waited for him to say something. He didn't say anything but I saw him place his hand on his neck and rubbed the spot. I blushed at how I thought of marking him but quickly shook those thoughts away. Oikawa is my best friend and yeah I care about him but he would never feel the same.

We began to walk away from the water fountain towards a set of stairs for our class. I sighed as I fixed my clothes a little and my hair. I heard oikawa mumble something but then cleared his throat and repeated himself.

"They're quite nice" he simply said as he gave me a quick bye and a thank you and ran to the stairs for his first class. I sighed as I smiled to myself. I rubbed my neck and closed my eyes. Damn I really do like oikawa huh.

"Hey (y/n)! Practice was so long today~" Oikawa whined as he sat next to me as his sticky and sweaty skin was shown brightly. I took a sip from my bottle as I became thirsty but I didn't get any water. I wiped my forehead on my shirt and breathed really heavily. I always give it my all, even if it's just practice. I went to take another sip but it was empty. I groaned as I sat it down next to me.

"Oh I'll go refill it since I have to too!~" he said as he shot up and wiped his forehead with his jersey and took my bottle with a smile. "Be careful, those pills might have worn off by now" I said but I turned around and he was already gone.

I sighed as I got up and stretched my sore limbs and began to help my team clean and put away the equipment.

I was having a conversation with Iwaizumi about some tips for our positions that we play until a strong sweet scent came across my nose. I closed my nose again and Iwaizumi did as well. "Is...that Oikawa?" I asked him and he cleared his throat. "I think so but why can we smell it?" He asked as he looked around.

Then a shock wave ran down my body. I uncovered my nose and dropped whatever I was holding. "I'll go get it! ill be back" I yelled at him and he nodded.

I ran out of the gym and followed his scent. I sniffed around until another smell hit my nose and then another and another. I coughed to my elbow at how intense the smells were. I hurriedly ran over to the smell and I can hear soft whimpering and laughs.

I didn't take a second thought as I bursted open to the maintenance closet and came across of three guys with oikawa in between them crying as he held his shorts on for dear life.

"Get the fuck away from him before I beat all of you" I said with fury in my voice. My hands were clenched harshly as I stood my ground. They all quickly fixed their uniforms and left the closet as they ran over each other.

I really wanted to beat them to a pulp but I wanted to take care of oikawa. I walked in and closed the closet, turned on the light and crouched down and his scent was way sweeter than before. I held my jersey over my nose as I coughed. "Geez your smell is so intense why is that?" I asked as I looked at him confused.

He didn't answer but his face was flushed with embarrassment as he let go of the tight hold he had of his shorts. "I-I...think I'm....in h-heat-t" he said as he whined by the end of the sentence. My cheeks grew red at the comment as I looked around nervously.

"I-oh I'm sorry let's get you home-" I began as I got up to pick him up but he pulled me back down next to him. It made me release my grip from my jersey and his scent was once again shown. "(Y/n)...let's do...it" he moaned as he gripped my arm as he looked at me with lustful eyes.

I can't do it. He's my best friend and it's something he'll probably regret later on. "No we can't. You're going to regret it later" I said as I sighed softly. His grip on my arm was not leaving a bit.

"(Y/n)~...if I were to be...marked and...mated...I would want it to be..you" oikawa struggled to say as he started to move around and moaned as he shot his hand on front of his shorts to hide his boner that was growing.

"Fuck oikawa, please don't" I said as I slapped my hand in front of my face to clear my head. I sighed as I was contemplating on what to do when I heard shuffling and it sounded like something sticky was present.

I drew my hand from my face and yelled lowly at the sight. Oikawa was stripping and he had slick all over his thighs and bottom of his legs.

"Please..please (y/n)!" He kept whining as he began to cry towards me. He crawled on my lap and straddled me with only his boxers on. His clothes were discarded all over the closet.

"Oikawa look at me" I said as I grabbed his cheeks softly and made him look at me. "Do you seriously want this?" I asked wanting to hear him consent to me. He smiled as he began to grind against my shorts and it made me groan.

"Yes (y/n)! Please please!" He pleaded again as he kept grinding against me. I softly smiled as I brought our faces together as I kissed him softly. He pushed harder though making our kiss even more intense.

I softly laid him on the floor as I discarded my pants and shirt and neatly put them to the side. "Okay I'll go slow on you since this is your first time-" I began as I looked all over his exposed naked body.

"Hurry up (y/n)! I can't I need you to touch me.." oikawa whined as he hiccuped loudly. He ran his hands through his body as to show me. He moved his knees apart and his hole was gaping for something to grip on. I groaned at the wonderful sight and gulped.

"...please put it in and touch me~" he said as he gasped. I got closer to him as he moved his arms around my neck and gripped my hair. I positioned my dick around to find his hole. "Hold your breath for me" I said as I heard him do so as I slowly entered him.

"Ahh-h~ fuck (y/n)! You're so big" he moaned as he arched his back as I kept entering him slowly. I was breathing heavily as he kept clenching on me.

"I'll start to move now okay?" I said as we stayed still for a few moments. He nodded as gripped my neck tight. I brought his thighs up and wrapped his legs around my waist. I slowly backed out and entered back in.

He moaned loudly in my ear and it aroused me even more. "You...k-keep growing in me!" Oikawa moaned as I pounded in him. I gripped his tiny waist as his nails dug in my back.

"Fuck oikawa. You feel so good~" I moaned as I kissed his neck and started to leave hickies. Oikawa didn't let any moan stay silent. He moaned right in my ear for me to hear loud and clear.

I nuzzled my face against his neck and smelled him. He smelled so fucking good I couldn't get enough of him.

"(Y/n)! (Y/n)~~~" he moaned over and over again making me hit his prostate straight on again and again. His mouth was wide open as his lewd words left his mouth.

"Please..." oikawa said as he moved his neck to the side and exposed his bright neck. I stared at it for a good moment but shook my head. "I can't oikawa" I said as I moved my hands back down to his thighs as I gripped them tighter and moved faster.

"Wh-aH!...why not?" He tried to ask as I hit his prostate quite hard. I clenched my teeth as I tried to think of something else.

I turned again and saw that oikawa was a full mess. Frazzled hair all over the place, soft rosy cheeks and his closed eyes as little tears were visible. He looked so beautiful.

I dropped my face on his neck as I began to cry but didn't slow down my pace. I let go one of my hands on his thighs and moved it to his hard dick. I pumped it rather fast and it made him flinch and jolt at the sudden sensation.

"Ah-!..w-what-!" He moaned and shot his eyes wide open. His back arched as our chest met closely. I sniffled as I brought my teeth towards his neck. "I'm close-! (Y/n)! I'm close!" Oikawa moaned and I rolled my hand on his dick.

"Me...ugh! Me too!" I groaned as I felt myself getting close as well. My thrusts became sloppy but I didn't stop my pace for anything.

Oikawas moans began to get higher in pitch as I felt hot liquid on my hand. I let him pump his cum out as I cummed inside him. I drew my teeth and brought them down harshly on his neck.

I heard him wince in pain as his nails dug themselves on my forearms. I cried as I could taste his blood on my teeth. My hot cum was dripping out of his hole as I pulled off from him.

I let go of his neck and lapped at his blood that was oozing out. I got up and silently went around to find some towels. I came back and wiped oikawa all over and kept apologizing.

"Why are you apologizing (y/n)?" He asked as he sat up and fixed his hair. I didn't respond as I cleaned myself and began to dress myself back.

I slipped on my jersey as I looked towards oikawa as he slipped his jersey back on backwards. "You put it on wrong here" I said as I slipped it off of him and placed it correctly.

"(Y/n). Do you think I'm going to regret this?" He asked in a serious tone. I sighed and looked down and nodded. "Well yeah. I'm a guy and also your best friend" I said as I looked down towards my shoes.

I heard him giggle and I got mad. "What are you laughing at?" I angrily yelled as I held onto his collar. He kept laughing as he brought his hands up in defense. "If I didn't like you, I wouldn't have asked you to mark me (y/n)!" He said as he showed me the mark I made.

It was so big and I shot my hand and pulled his shirt back up to cover it. "I'm so sorry oikawa" I apologized as I bowed with my deep condolences.

"(Y/n) you're so dumb sometimes!" He said as he brought my head up with his hand and looked deeply to my eyes. "I.like.you." He said so I could understand. I blushed at his words and looked away.

"Now let's go before the others find out!" He said as he fixed his clothes once again and I did as well. We exited the closet with the towels we used to throw them away.

We walked back to the gym and I stopped him before we could enter again. "That mark suits you so well" I said towards his ear as I kissed it and left to enter the gym again leaving a blushing oikawa behind.

"(Y/n) you're so mean!"
