Drool was slowly pooling from your mouth as you just woke up, the sun beaming straight into your eyes, causing your eyelashes to flutter and flip your body to face away from the sunlight. Before you could close your eyes again, you reached out for your phone on your pillow and went to check the time, which is a routine you developed without noticing. 

1:53, you noted. But, you immediately stood up and wiped the drool from the corners of your mouth to realize that it was July 9th. Shit. You cursed at yourself in your head while frantically throwing on whatever you saw. 

Black shorts and a baggy t-shirt representing your school, Date Tech. You went to the bathroom to see what you overall really looked like taking into consideration that your hair must have been a bird’s nest from moving a lot in your sleep. 

“Huh.”

You didn’t think the shirt you chose to wear would cover your shorts, but you shrugged it off. Hopefully some idiot doesn’t think that you’re not wearing anything under it. Thankfully, your hair wasn’t all that much of a mess- i mean, it was still a bit frizzy and in a loose ponytail, but who really cares? Definitely not you.

You threw on some white crew socks with some black shoes you saw under your bed. While you struggled a bit to put your shoes on, you heard something coming from your bed. It was your phone vibrating. 

“I swear to god, if it’s some annoying son of a bitch-“ you stood up and tripped since you were trying to put on your other shoe standing up while your foot’s in the air. As you peered over your phone, you saw that it was a notification from Koganegawa and you sighed in relief. 

When you had your shoe on you grabbed your phone and went to go and read what he messaged you.

“Hey, Y/N! I know that you might still be asleep, but i wanted to let you know that i’m having a birthday party which starts at around 4, and that you’re invited! I can’t wait to see you there. Even though it’ll be a small little party, i think you’ll REALLY enjoy it. Aone, Kaname, Futakuchi, and Sakunami will be there. I hope to see you there soon!” sent at 11:27 AM

As you read 11:27 AM your expression was covered in horror, but.. It could’ve been worse. For example, maybe it was sent at 9am and here you are just sitting on your ass, waking up at basically 2PM. You smiled a bit thinking of the scenario in your head, visualizing what you would act like if they actually happened. You quickly stopped yourself, though. something was a bit off in this text. You reread it at least 5 times to finally recognize what’s wrong with it. 

“uh kogane, you didn’t even give me the location” sent 2:07 PM

Sadly, you weren’t really the patient type and when 10 minutes had passed you started to get a bit antsy. Your leg was basically vibrating based off of how fast your foot was lighting tapping against the ground. 

Fuck it.

—————————

You were now furiously knocking on the door- at this point you don’t know if it was either knocking or punching it with the side of your fist. Like the idiot you were, you didn’t even try to use the door knob. When you were tired out from yelling and knocking on the door, that was the time when you decided to use it. 

And, it worked.

“Kogane! I’m coming in..” you slowly dragged out the n’s in the word “in” as if you were screaming “ready or not, here I come!” in a classic game of hide and seek. 

When you walked in, you could see streamers and balloons around the house, the little “Happy Birthday!” sign greeting you. Food was spread out in the kitchen, the dining room table was all set up with a birthday table cover and everything. You could clearly see the effort he put in based off of the mess he made in the living room. You could see the plastic bags the decorations must have came in when he bought them scattered around the living room. His house looked like a little kids birthday party, but in a good way. He really did go all out. The poor guy did this all by himself. You frowned at the thought, and then suddenly had a sly smirk on your face. 

You quickly took your shoes off and began to quietly walk around the house, wanting to surprise him and give him a big old innocent birthday hug. Now that the thought crossed your mind, you totally forgot to get him a birthday present while on the way here, but you didn’t know the party would be at his house- that could be your excuse. You nodded to yourself, agreeing with the thought. 

His home was oddly quiet, but you continued to walk around the house. Eventually, you came upon a door that was slightly opened and you peeked your head inside without hesitation. 

Koganegawa was slowly stroking his long, veiny cock with his right hand, his hips thrusting up into his fist every now and then. Some strands of his hair were stuck to the sides of his head due to the sweat that was forming on his body. The little groans he let out was causing your thighs to clench together, trying your hardest to not picture what he would look like between your legs. This dirty thought of yours caused you to let out a small moan, quickly slapping your hand against your mouth, hoping he didn’t hear. You slowly sat yourself on the ground, trying to even out your breaths since it was such a close call, but you were cut off when the door right beside you swung open. You screamed in surprise and fell on your back. You could clearly see Kogane’s unattended, throbbing cock against his boxers. Goddamn was it bigger up close.

“Uh.. Happy birthday?” you awkwardly announced, trying to break the cold, uncomfortable silence, waving both of your hands in a celebratory, jazz hands motion.

He grabbed your wrist, helping you off the ground and led you to his bed. He stood in front of you, hands on his hips staring at you, obviously expecting an answer. 

Instead of giving him an answer right away, you took this as a chance to admire the sight in front of you. His toned body was enough to make you drool, his abs glossed in sweat and goddamn.. his fucking thighs. They were pretty nice, not gonna lie, you smirked to yourself. Honestly, you wouldn’t mind if he just stood there all day. He should be put in a museum. Your eyes slowly went to his-

“Y/N! I’m still here! What were you doing outside of my door??” he yelled, hands out in front of him, expressing his question more through his movement. 

“Listen, I- You.. You didn’t answer my goddamn text!” you replied, your eyes darting to the other side of the room, trying your best to not make eye contact with him. “So i.. came to your house, and when you didn’t answer the door i just.. Walked right on in.” you were putting your best efforts to lighten the mood but it wasn’t exactly working as you hoped it would.

“Then you decided to watch me jack off my dick behind my door, too, right?”

“What else would i have been doing? fucking idiot..” your voice trailed off at the last part, not wanting him to hear. 

“Would you like to repeat what you said, Y/N?” he teasingly asked, cocking one of his eyebrows up. 

“Uh no, fuck off, yeah?” you attacked right back. You leaned forward, your elbow resting against your knee as your head rested in the palm of your hand. You stuck your tongue out at him like a child, waiting to see his reaction. 

He hummed in response, looking down at you with his arms crossed. “Y/N, are you even wearing anything under that?” You almost choked as you held in your laugh. I guess he was the idiot. 

“Yeah, I am. Do you think i’m stupid or something? I would never leave the house with no pants on. Bold of you to assume that.” his eyebrow was still in the same position as if he didn’t believe you. You stood up from the bed.

“Kogane, look” he tilted his head at you and you lifted your shirt up. He immediately looked away and you had to repeat yourself. “No, look at me, idiot! I’m wearing shorts, see?” he slowly turned his head towards you and he looked puzzled. This man is as stupid as an elementary schooler, you don’t know how he’s still alive by now. 

“So i’m guessing you have a birthday present for me?” he joked, but your mind clicked. It wasn’t your birthday hug idea, but something else. 

“Actually, yes, I do. Can you sit on the bed for me real quick?” he quickly sat on the bed, oblivious to what he’s getting himself into. 

You slowly got onto the bed and sat around him, your arms wrapping around his waist, your hands inching their way to his boxers.

“What are you-“ 

“You already know what i’m doing, it’s your birthday so just let it happen, okay?” he nodded with a gulp, and you continued your ministrations. 

Your left hand slowly lowered the boxers off of his legs, causing his dick to spring up against his stomach. He groaned at the feeling, which made you eager to continue even further. You didn’t expect for his dick to be so long. It was average girth but holy shit was it lengthy. Your right hand began to stroke his cock, slowly at first, immediately teasing the tip with your thumb, wiping the precum off and onto his shaft. Feeling him shiver against your body made your cheeks flush and had your right hand slightly shaking in excitement. He noticed this and took action by wrapping his large, rough hands against yours, guiding your hand up and down at a quicker pace than you had before. His moans were becoming more apparent and louder, signaling that he’s close to his release. Kogane’s hands never left yours as his grip tightened, going even faster. Feeling how eager he is to cum and just by watching him help you jack him off is making you even wetter than you were before. 

“God, Kogane you’re so goddamn cute..Feeling your hand against mine while you guide me to fuck your cock with my hand is so fucking hot..” you felt his cock twitch at your words and you smirked through your bright red cheeks, lowering your head against his dick and filling your mouth with his long cock. Kogane threw his head back in pleasure while pushing your head down against him, his cum filling your mouth, making you choke. You remain still, though, allowing him to wait out his release. 

He lifted your head up off of him and when he looked at you with his cum dripping down the sides of your mouth, he immediately became hard again. 

“Didn’t know you were that eag-“ you were cut off when Kogane grabbed you by the hips and threw you right under him. The way he towered over you made you want to cower under a blanket and hide, but at the same time it just turned you on even more. It was almost like a prey being hunted by predator scenario.

“Kogane what are you-“ the smirk on his face was like one you’ve never seen before.

“Oh, how the tables have turned.” the sly little dumb smirk he still had plastered on his face made you want to flick him upside the head, but realistically you couldn’t since you were vulnerable as all hell under him.

He didn’t hesitate whatsoever to pull your shirt off of you. Already, your shorts were gone and the same with your bra. You were lost- it was like a switch was flipped with him. You didn’t know he had a side like this to him. 

Kogane went up to your neck and purposefully breathed against your neck causing you to jump. He soon started to leave small, gentle bites on the same spot, letting him leave a long lick against it, hurriedly wanting to whisper against your ear something god knows what where he got it from. 

“I’m going to fuck you senseless until you learn who’s the boss around here, okay sweetheart?” chills were sent down your spine, your heart thumping in your chest, positive that he could hear it. Your cheeks were the brightest shade of red to the point it looks like a child got into their mom’s makeup. But, you didn't know if he watched some really hardcore porn or what, but did not know at al that he had that in him.

His two, long fingers were suddenly teasing your entrance, causing you to let out a small moan, but you acted quickly as you covered your mouth with your hand, not willing to give in to him. Not pleased with your actions, his fingers delved inside if you, pushing in and out of you at a rather quick pace, making sure to curl his fingers in all of the right spots. 

“Can you not hide your moans from me? Pretty Please?” he gave you those puppy dog eyes that you always hated. You shook your head. He shrugged in response and positioned himself against you, your eyes widening in shock. Before you could stop him, question him, or anything, he was already buried inside of you, letting out a loud grunt. 

“I’m going to fuck you really hard, Y/N. I know you like that. You like it when guys fuck you until you can’t walk, right?” he emphasized the last word by slamming his cock deep inside of you, straight towards your g-spot. You basically screamed by the intense feeling, and he only just started. 

“Finally opening up to me, pretty girl?” he pushed your legs up by your head and began to drill his cock into you nonstop. His tight grip on your hips was bound to leave a mark afterwards. The sound of his hips slapping against yours could’ve been enough to make you cum alone.

He pulled out of you and you glared at him.

“Don’t worry, don’t worry.. Come here.” he motioned his hands for you to come towards him. He led you towards the wall.

“Jump” you obliged and he pinned you against the wall, making sure to not waste time by quickly inserting his pulsing cock inside of you. 

“Fuck!” he looked at you, giving you a quick peck on the lips before he started to move inside of you. His thrusts began extremely slow, obviously teasing you. 

“You know what I want.” Kogane’s thrusts became even slower before they came to a stop.

“No, I don’t, i can’t read min-“ your snark remark was cut off as you were given a hard, rough slap on the ass. You looked at him, and he nodded as a signal to go on. You sighed.

“Fuck me.” You sarcastically said in a dull tone, making him annoyed on purpose.

“Come on.. you know you want to. Quit lying about it, Y/N!” he began to rub your clit with one of his fingers as he waited.

“I want you to fuck me till your hearts content. I want you to fuck my pussy until i beg you to stop so i want you to quit messing around and get on with it already!” a small whine was released at the end of your words, but Koganegawa seemed satisfied.

“Whatever you want..” He grinned, He pushed himself further against you, making sure you were well propped up against the wall, and began to thrust at a rapid pace, causing you to grab onto his shoulders to give you more support. 

“God fucking dammit you’re so tight..” your walls were clenching around him like a vice. His cock filled you up so well, but the fact that his dick was brushing against your cervix was throwing you off the edge. It was impossible to think that someone could fill you up so good, and so perfectly. 

“Fuck, fuck! Please don’t stop, Kanji! Right there, right there!” his cheeks flushed at hearing his first name slip past your lips. The pace that he is holding at the moment, you could basically say he was using you like a sex doll. He was like an animal in heat, he showed no signs of stopping whatsoever, and it didn’t help that you used his first name.

“Say it again, please.” he whines against your ear, his hot breaths driving you to the edge even more 

“Kanji!” you moaned, practically chanting his name. He loved the way you said his name. The way his cock thrusted in and out of you at such a quick pace while your cum was coated around it, was the second hottest thing next to Kogane. The way he moaned, the skin slapping against skin was too much.

“I’m gonna cum, I’m gonna cum!” you screamed, but to your surprise Kogane kept on thrusting in and out of you, chasing his own release. You knew he wasn’t going to stop until he came.

“Kanji, please cum, I’m begging you Kanji! You fill me up so good, I love the way you fill me up is so perfect just like you baby-“ and that was it, that’s all that took.

“FUCK! Y/N I love you I love you!” he came inside of you, slowly moving his hips inside of you to ride out the overwhelming feel of pleasure. Your tongue was lolling out of your mouth at the overstimulation, and Kogane let out a small chuckle before carefully carrying you to his bed. 

“Where the hell did you learn all of that from, Kanji?” you said through heavy breaths.

Futakuchi leaned on the door.

“From me.” he pointed at himself with a proud smile before walking off.
