a/n: The ending is... more or less abrupt, but I wanted a chance to possibly make a second part in the future because I have a lot planned for these two!

“Grow up.” His dark eyes avoided your general area as he stood before you. He wasn’t close enough to hear how fast your heart beat, but you could smell him. That wonderful, intoxicating, warm smell of his cologne. You shouldn’t be thinking about how delicious he smells though, you should be mad at him. 

“I thought our one rule was supposed to be good communication.” you start, but he interrupts with his melodic laugh. 

“You cannot be serious right now y/n.” Those eyes are now glaring at you. You wish you both weren’t headstrong because he looks so sexy right now with his silky raven hair combed over to one side of his head. He had a cream-colored shirt on that clung to his muscular form. He’d rolled up the long sleeves to expose his forearms and the intricate tattoo that curled up the length of his right arm. 

“You’re the one that allowed me to kiss you!” You exclaim, frustrated with the games he was trying to play. Suguru runs a hand down his face and steps closer to you, eyes narrowed. 

“You’re my best friend’s little sister. This cannot go on.” His proximity sends a shiver up your spine. You could do one of two things, bow your head and accept what he was telling you, or kiss him again. You bite your bottom lip, tempted by the latter option. 

“Toru doesn’t have to find out.” You knew your older brother would be weird about the two of you being intimate with each other. Satoru had always been protective of you, claiming he was the best big brother to ever walk the Earth. As his little sister, you couldn’t help but look up to your shining older brother. He was pretty great at times. After all, once he heard about the kids saying mean things about your weight to you on the playground he’d practically made dirt their favorite food. Suguru rolls his eyes in frustration and you can’t help but watch the tick of his jaw as he tries to decide what to do with you. 

“You know he’ll discover us eventually.” His eyes soften ever so slightly as they take in your face. You smirk up at the tall man in front of you. 

“So there’s an us now?” You give into the electric pull between you and his body. Reaching out a tentative hand to his bicep, you curl your fingers around the girth of his upper arm. You were hopeful Suguru would understand what this simple touch meant. 

You wanted him. Needed him. Ever since the two of you were younger and Satoru introduced his new friend to the unexpecting you. His hair was slightly shorter back then and greasy. He’d grown into himself over the years, learning how to take care of his hair, body, and responsibilities. 

“Y/n.” His sigh is long and it gives you a chance to move your hand up to his cheek. 

“Suguru.” Your voice is barely above a whisper. His eyes are tracking your expression, weary of what might happen if he looks away. 

“This is a bad idea.” He silently tries to sway you one last time to forget about him. How could you? Suguru Geto was so good at communicating with his eyes that you already knew what he wanted. Your hand slides down his jawline and you palm his sternum. 

“Aren’t all good ideas bad?” You swallow hard, unaware of the strain you were having on Suguru’s restraint. “Just one kiss,” You breathe, leaning up on the tips of your toes to level your lips with his. 

“You know it’s not going to be only one,” Suguru backs you against the kitchen counter. You gasp slightly as he plants an arm on either side of you against the granite. Before you can think of how your breath smells his plump lips are encasing yours. Your eyes roll closed and you allow your hands to run vigorously through his hair. A small moan escapes your lips as Suguru palms you under the oversized shirt you wore. He breaks from the kiss and bumps his forehead against yours. “Fuck, why’d you have to moan?” He hisses, eyes squeezed shut. You feel a pang of anxiety course through you. Did he not like that you moaned? Was it weird that you felt pleasure from the contact of his hand on your skin? 

“I'm sorry-” You start to say but he kisses you aggressively this time. Hunger seeps through his mouth. He moves from your lips down your jaw and to your neck. Your body melts under his touch. Suguru nips at the soft spot between your neck and shoulder. You let out a little yelp and turn to meet his gaze. 

“I swear you’re going to make me go crazy.” He rolls his lips under his teeth, waiting for you to respond to his confession. 

“I think you’d be a sexy mad hatter.” You tease. A grin pulls at the corner of his mouth. He smooches your neck, then trails kisses up to your nose. 

“You’re incredibly hard to say no to.” His dark hair runs like midnight waves messily around his face. 

“It’s a power I have to use with great responsibility.” You laugh, closing your eyes as you do so. When you open them back up his eyes are observing you again. It makes you squirm slightly, but not because you were uncomfortable. It was for another reason entirely, kissing was nice but you wanted to know how good Suguru was in bed. A devious query you wanted to be answered as soon as possible. Your ears perk up as a noise comes from the front door. Suguru’s eyes go wide and he scrambles away from you, moving toward the fridge. He opens it and pretends to look for something. You on the other hand busy yourself with scrolling through the first app you thought to open, which happened to be Webtoons. Satoru strolls through the door, a huge smile on his face. His silver hair is pushed back by his sunglasses on top of his thick head. 

“Well, look at that. You both are the exact people I wanted to see.” He hands his keys on his special hook and then starts toward us. Suguru gets a water bottle out of the fridge and hands it to me. You nod toward him signaling your thanks, but he doesn’t look my way. “I had a long day at work, come greet your brother.” He extends his arms. 

“Needy bastard.” You grumble, but you oblige to his request. He wraps his long arms around you with a tight squeeze. He kisses the top of your head and then holds you at arm's length. His head tilts as he studies you, then his brows furrow. 

“What’s this?” He questions, zeroing in on something to your side. 

“What?” You reply, twisting to figure out what he was referring to. Satoru holds you still and touches a spot on your lower neck. 

“Right here. It’s all red and blotchy.” His bright eyes flit to meet yours, concern and anger written all of over his face. You knew your brother was thinking of the worst. Surely a red splotch on your skin couldn’t be a bug bite, no that was too simple. 

“Probably a bug bite.” You laugh and go to cover the area with your hand but Toru is quicker than you. He feels it again and shakes his head. 

“There’s no bump.” His eyes narrow and he holds your hand away from your neck. “Did you have a boy over while I was gone?” He interrogates. You push your older brother away with an annoyed sigh. 

“No.” You dismiss. “Maybe I’m getting a rash from your stupidity.” Satoru sighs and finally leans his long body against the counter. He pinches the bridge of his nose and then drags that hand down to his jaw. 

“Sorry sis, I just didn’t want a repeat of Stuart.” He sighs again and Suguru basically chokes on his next breath.

“Who’s Stuart?” He quizzes through stifled laughs. You glare at him but he ignores you. Your older brother rolls his eyes and gestures to you. 

“Some dude that somehow had sex with y/n.” He replies, a sneer appearing on his lips. Suguru stops laughing and finally looks at you since Satoru had arrived. His eyes are searching your body like there are going to be remnants of Stuart there. “Anyway Geto do you want to head over to the bar? Daddy’s thirsty.” Satoru pushes off the counter and goes back toward the door, grabbing his keys. 

“I really hate when you call yourself that.” Suguru groans and goes to follow him, removing his eyes from you. 

“Well y/n we’ll be back when I’m nice and drunk. I need to fuckin’ forget about today.” He shows you a huge grin and lifts a hand to wave, his key ring around his pointer finger. You narrow your eyes at your older brother.

“You just got home though,” You start walking toward him. Satoru had been drinking a lot lately, and you were worried. If he continued like this it was going to turn into a serious problem. “Why don’t we watch a movie?” You try to convince him to stay. Satoru closes the distance between you and wraps his arms around you in a brisk movement. 

“I’m going to be alright y/n, besides I’ve got this hunk to protect me.” He jerks a thumb over his shoulder at Suguru, who looks up from putting his jacket on. 

“Yeah no, if anything I’m leaving your gangly ass behind.” Suguru winks at you and a flush rises through your body, surrounding your cheeks in a rosy hue. Satoru dismisses what his best friend had said and kisses your forehead again. 

“I’m sorry we’re leaving you alone, but just think of it this way, at least you might get another video of me trying to twerk to Mary Had a Little Lamb.” Satoru ruffles your hair with that signature smile of his, then turns to leave. Once he’s through the door Suguru lingers for a moment. You can tell he wants to say something about what happened before but is afraid Satoru will walk through the door again. Oh, what the fuck, you couldn’t resist teasing him. You lean against the wall and twist your hair around a finger. 

“Hurry back, I’ll be waiting in my room for you.” You move forward the slightest bit, enough so that your nose would be filled with his scent. “I like the idea of you in between my legs.” You turn to leave but Suguru catches your wrist and pulls you into him. He leans down to your ear, his hair tickling your nose, but it smelt like rain and wood. 

“We’ll flip a coin to see which head goes first.” He then lowers his mouth to the spot he left on you earlier and licks it slowly. “I’m going to fuck you until the sun kisses your skin.” His eyes lift to meet yours and your breath gets stuck in your throat. You could feel the electric pull of want, need, and pressure in your body. You try to lean forward to kiss him, but he pulls back. “Ah ah ah, not now princess, I want you to be yearning for me to satisfy you when I get back.” He smirks at the look on your face and then turns to leave. “See ya y/n! Thanks for helping me find my phone!” He lifts a hand in a small wave. Satoru sits in his car, drumming against the steering wheel to a song. You finally let out a shaky breath and shut the door behind them. You press your hot skin against the cool of the door. Holy shit. Did that really just happen? Were you about to have sex with Suguru Geto when he gets back from drinking with his best friend, your older brother? Your pussy practically throbs with excitement. You’re sure if it had the power to speed up time, that’s what it would be doing. 

Suguru was no Stuart, he was probably bigger, more experienced, just an overwhelming presence. You pull your lips under your teeth and glance at the clock. How do you even get ready for something like this? Shower, shave, and busy yourself to make the time go by faster. 

3 hours had passed since the two of them had left. You’d been laying in your bed reading some wholesome comic for the majority of that time. Your shower had felt magnificent and you wore a nice pastel pink bralette and a black thong. Was it overkill since they’d be on the floor soon? Yes, but you wanted him to know you were serious enough to try for him. You had put on the same oversized shirt you wore earlier and snuggled into bed. You’re about to call it a night, considering it was almost 1 in the morning, but that's when your door swings open. Suguru stands panting in the doorway, assessing you covered up and on your phone. 

“Where’s my brother?” Is the first thing you think of to say. Suguru smirks and tilts his head at you. 

“Left em’ at the bar.” He reports, the teasing smirk still on his lips. You roll your eyes and he stumbles into your room, closing the door with his foot. “He’s downstairs on the couch. I’d rather not wear myself out trying to drag his ass up to his room. Also doubles as you being able to be as loud as you want.” He’s still closing the distance between the two of you and you can feel the anxiety start to creep up your spine. Shit, this was happening. 

“Well, where is the coin?” You ask, trying to prolong this moment so you could mentally prepare yourself. Suguru stuffs his hand in his back pocket and produces a silver coin. He flips it and time seemingly slows down as it lands back in his hand. You watch closely as he turns the coin over on his other hand. Still covering it he looks up at you. 

“Heads or tails?” He grins. You look away from him, nervous for the first time in a while. Stuart never made you feel electrified when you both were about to have sex. Suguru on the other hand had this presence that made you want all of him. 

“Heads, you eat me out.” You hear yourself say, eyes locking on his. He lowers his hand to show you what the coin had landed on. A small gasp escapes your lips as the head of some president stares back at you. 

“Fine dining it is.”  Suguru tosses the coin on your nightstand and grabs the end of your blanket, flinging it to the side. You yelp as the cold air stings your warm thighs. He gets on his knees and ties his hair back in a bun. He then taps the edge of the bed, beckoning you to come to him. You scoot over to him, positioning yourself neatly in front of him. He smiles up at you, his eyes glinting with some sort of emotion you can’t quite decipher. “Are you okay with this?” Lazily dragging a finger up and down your inner thigh. You suck in a breath and nod. Suguru bites his bottom lip and places both of his hands on your knees. He pushes them apart slowly, taking in the black thong you had on. A smirk plays with his lips as he meets your gaze again. “Did you put on these for me?” He playfully asks. You press your lips together and avoid eye contact. “You’re adorable, princess.” He spreads you apart more and you're suddenly looking back at the beautiful man in between your legs. 

“I-I’m nervous.” You admit, shying away from his scrutinizing gaze. He leaves a light trail of kisses on your thigh. 

“Don’t be, just focus on the pleasure.” He mumbles against your reddening thigh. That’s when he grabs hold of the hem of your thong and pulls them off you. He tosses them over his shoulder, eyes trained on your exposed pussy. He groans low in his throat. “Fuck, y/n, you’re so fucking stunning.” He wraps his arms around your thighs, pulling you closer to him. He roughly kisses your thigh and frees a hand to reach your throbbing entrance. He glances up at you through his lashes and then pushes a finger into you. A light moan comes from your lips and you can tell Suguru likes the sound of your little moans because another finger is already inside you. You start to squirm with pleasure as he pumps them in and out of you. 

“Ah, fuck, right there.” You cry out, enjoying the way his lips kiss your thighs and his fingers feel your insides. A budding pressure builds in your lower abdomen, threatening to explode any second. Suguru seems entranced by the way your cunt gobbles up his fingers. You start to tremble and reach out a shaky hand to grab onto his wrist. “Please, I want your tongue inside me.” You rasp, eyes rolling back in your head. He smirks against your thigh and wiggles his fingers around. 

“You’re so needy for my tongue.” He teases but removes his fingers slowly. “Tell me what you want y/n.” You let go of his wrist and try to catch your breath. 

“I want to c-cum on your face.” You manage to stutter out. Suguru licks his lips with a low grunt. He takes a deep breath in. 

“Glad to know we’re on the same page.” Then he dips his head in between your legs, angling his head so his tongue can sweep across your needy clit. You shudder at the contact of your already sensitive pussy. He places his lips firmly around your clit and starts to suck, sloshing his spit and your juices around. You start to grind against his face, yearning for the sweet release. He hums with you in his mouth. Your fingers tangle in his hair, pulling him into you as his tongue fucks you. You start to quiver against him. 

“Oh! I’m going to cum! Suguru!” You moan out his name as your stomach twists in knots. A splintering orgasm pushes you to keep Suguru’s head right where he is. He obliges by lapping up your juices. Once you feel the fire start to subside you release his head. You let out a breathy moan as Suguru licks you off his face. 

“You taste like honey.” He grins. You stare at his angled face, taking in the scene of him with your juices on his lips. You sit up a bit more and glance down at his crotch. He’s pressed against his pants, straining the fabric. He notices me peering at him and shifts himself. “Jeez, now you’re making me nervous.” You place both hands on his shoulders and push up to a standing position. 

“Get up, it’s your turn.” You move out of the way so he has room to take the spot where you just were. 

“Y-y/n you really don’t have to do-”

“Now.”

“Jeez okay.”

Suguru stands and pulls at the hem of his pants. He steps out of both his pants and boxers and you watch as his erection springs forth, nearly hitting him in the abdomen. He places himself on the edge of the bed and you hear a deep intake of breath from him. 

“Don’t worry, I’ll be gentle.” You coo. He rolls his eyes and braces himself against the edge of the bed. His hair is a mess after you mangled it, but for once your eyes are more inclined to look at his hard cock. It’s bigger than you expected, probably around 8 or so inches. You're not sure if you’ll be able to take the whole thing in your mouth, but you’d try your hardest for Suguru. 

“Come on, wrap those pretty lips around me.” Suguru coaxes in that deep voice of his. You look at him as you sink to your knees in front of him. You wrap your fingers around him and rub the head with the pad of your thumb. He shudders and you like the way a deep grumble comes from within him. You bring your lips to the head and place a gentle kiss there. “Fuck.” Suguru hisses. Then you take his cock in your mouth, hollowing your cheeks and bobbing your head slowly at first. Suguru moans and hisses about how great you’re doing. You can feel his cock twitching in your mouth and you swirl your tongue around him. Suguru’s hand then grabs your head, pushing you down on his cock. You choke at the sudden clog of him in your throat. You try your best to continue, but he’s now hitting the back of your throat, making it hard to focus. You squeeze your eyes shut as tears form in your eyes. “Right there y/n, fuck me.” You were trying to, but Suguru was filling your mouth. You look at him through your lashes, watching him hand his head back with breathy pants of pleasure. He looked majestic even as he used your throat to get off. 

The cum is hot on your tongue as he spills into your mouth. A shudder ran through him, his hand clenching your hair. His cock slips out of your mouth, trailing a little bit of semen down your chin. He yanks your head back and a hungry look encases him. 

“Swallow it.” He demands. He didn’t have to tell you twice, you had planned to anyway. You were his little whore and he tasted almost as delicious as he smelt. Suguru’s chest rises and falls with quick breaths as he watches you lick the cum on your chin. 

“Yummy.” You hum, maintaining eye contact with him. He’s still holding your head back and he seems to realize he could be hurting you so he gives you some slack. Though, not too much, it’s obvious he likes to be in charge. “Kiss me Suguru.” You pant. He watches you with those careful eyes of his. 

“Beg me.” He hisses. You nearly melt into his demand. God, he was so fucking sexy when he told you to beg. 

“Please Suguru, I need you to kiss me.” That’s all it takes for him to crash his lips against yours. Your lips are swollen from sucking him off, but you love the slight sting as he slides off the bed to join you on the ground. He nips at your soft jaw and grinds against you. 

“Fuck, you’re so sexy.” He growls, hand still caught in your hair. “I can’t wait to fuck you y/n.” He’s about to move forward with this wonderful moment but you both hear footsteps outside your door. You feel a cold chill of fear surround you. You look back at Suguru, his eyes are trained on you. “He’s probably moving to his bed.” He whispers. 

Well, you sure fucking hoped so or this was going to be one of those bad ideas.
