Brother’s best friend Suguru
Suguru Geto x Satoru’s little sister reader
TW: Sexually explicit Content (Minors DNI)
Suguru Geto has been your brother’s best friend since you could remember. He’s been to every family event, every vacation, every important memory you have: he’s there all the time. When you were young, you had a crush on him. It really wasn’t a secret from anyone; It was obvious that Satoru’s little sister had a thing for Suguru. Everyone teased you about it, Satoru got mad about it, but Suguru was always kind. He would take special care to smile at you, hug you when he saw you, get you a gift on your birthday, etc. When your brother would say something rude about your crush on him, Suguru would come to your defense and either change the subject or remove Satoru from the situation. As you began to get older, Suguru remained the same, but you began to get closer to him. You would actually have conversations now, and bond over things you both enjoyed like music, tv shows, books, etc. It was becoming more mutual than when he would spend time with you to spare your feelings. Knowing this; however, didn’t take the feeling away that this all might be some sort of pity thing from him. You worried that his kind nature drove this attention he was showing you far more than genuine interest. So, you were kind like he has been to you, but you put up an emotional distance between the two of you. If you didn’t get your hopes up, if you could just keep him at arm’s length, maybe it wouldn’t hurt so badly when he inevitably found someone. Honestly, you couldn’t tell if your efforts were helping or not. Suguru was beautiful. He always had been. Women flocked to him, everyone wanted to know him; to be his friend, or…more. What chance did you have? Knowing this didn’t make the pain any less. You were in love with him. It never went away.
“Hey, YN?” You turned your attention from the book you had been reading by the pool to meet kind purple eyes.
“Oh!” Your book slipped from your hand and into the water where your feet were submerged. “Shit!” You cursed.
“Sorry.” Suguru laughed as he leaned over to retrieve the ruined book. “I forget you’re so clumsy.” He ruffled your hair.
“I’m usually not.” You grumbled as he handed you the soaked paper.
“What are you talking about?” His voice was exaggerated and full of sarcasm. “You’ve been like this since we were kids.”
‘Around you.’ You wanted to say.
“Did you need something?” You asked him, standing up from the pool and grabbing your towel.
“Oh, yeah.” His voice trailed off.
“What is it?” You turned to find his eyes lowered. Had he been checking you out? No, YN. Obviously not.
Suguru cleared his throat. “Sorry, your mom. She, uh, she wanted you to come inside to get ready for tonight.”
Tonight. Satoru’s birthday party. Every single year he outdid himself from the year before. Every year, you tried to come up with a good enough excuse to miss it. It never worked.
“What?” Suguru quirked an eyebrow. “I know you didn’t used to like his parties, but you’re grown up now. You’re not his dorky little sister anymore.”
“I’m still his dorky little sister.” You argued as you both made your way inside.
“No. You’re not.” When you found his eyes again, they lacked his usual playfulness that was normally just under the surface. Maybe he actually meant that.
“Either way, parties aren’t my thing.” You told him. “Are you about to get in?” You motioned to the pool now noticing he was wearing swim trunks with his tshirt instead of shorts.
“Here.” You threw him your towel. “Have fun!”
You didn’t see it, but Suguru watched you walk away until he physically couldn’t see you anymore. Truthfully, he had been fighting feelings for you for years now. What was stopping him from acting on said feelings? Satoru Gojo. He knew that his best friend wouldn’t approve of the two of you, so he pushed his feelings aside and pretended everything was normal. That was getting harder by the day. Especially when you walked around in your barely anything bikinis. Suguru knew he was pretty much in love, but there was simply nothing he could do about it.
“Where’s my sister?” Satoru yelled through the music and people crowded in the downstairs of the massive Gojo estate.
“Haven’t seen her!” Suguru yelled back.
Upstairs, you were about to pass out from anxiety. Your mother had forced you into a skimpy little dress that left almost nothing to imagination. You could barely move in it, and besides that, you were not the type of girl to wear dresses at all. Let’s not even mention the platform heels on your feet you couldn’t take two steps in.
“Why do I have to wear this?” You shrieked to your mother as she put the finishing touches on your hair and makeup.
“Because everyone needs to remember you’re a woman. You never dress up or go out. You’re going to die alone in sweatpants and a stained t-shirt pining over Suguru.” Your mother retorted.
“Well, Mother, maybe I would be ok with that.” You said crossing your arms to conceal your cleavage.
“Well no one else would be. You have a status to uphold as a Gojo. You’re going down there and you’re going to be pleasant and social. If you’re not, I’ll take your reading privileges, your phone, your iPod, your laptop, everything. All you’ll be allowed to do is hang out with Satoru and-“
She smiled. “You’re pretty when you try.” She pinched your cheek.
That’s pretty much what you were to the Gojos: a pretty face they could use to get what they wanted. Who you would marry had been a topic of discussion since you were born. For you, there was only one option. You knew that he didn’t return these feelings, but when you imagined yourself married, or in love: Suguru. Every time, it was Suguru.
You made your way down the stairs on wobbly, unstable legs.
“There you are!” You heard your brother over the music and noise.
Your eyes glanced past him to his best friend. He looked…pissed.
“Been looking for you!” Satoru shouted, throwing his arm around your shoulder and causing you to stumble slightly in your heels.
“Sorry, Mom had to vacuum seal me into this damn dress!” You explained.
Satoru laughed. “Sounds about right. But hey, maybe you’ll actually find a guy that’ll be interested in you! What do you think, Sugu?” Satoru looked to the dark haired man.
“What do I think?” He repeated looking you up and down. “I think she looks ridiculous.”
Your eyes dropped from his to the floor. Satoru laughed in your ear, but you pushed him off and began making your way far from the two of them. Because of the heels, you weren’t able to move quickly, and soon a hand grabbed your wrist. The sudden pull caused you to stumble, but strong arms caught you and pulled you down the hall and into a spare room. You knew who it was just by touch.
“I’m sorry!” He blurted as the door shut. “Fuck, I didn’t mean it like that.” His hands were still on you, holding your waist as he spoke. “I just meant…you hate it, right?”
“Maybe they have a point.” You still couldn’t look him in the eye.
“What do you mean?” His tone was soft and sincere as usual.
“They say I’ll never marry or even date anyone because I still have this childish crush on you. And because I put no effort into my appearance and, well I guess I’m kind of intense and abrasive, but mostly the you thing.” The words tumbled out of your mouth without a second thought. “But maybe you’re more of a dick than I thought. Maybe I’ve outgrown this crush. Maybe finally I can look at another man and actually consider them for more than a split second.”
He stared at you for a moment before he spoke. “I haven’t.”
“What?” You asked getting a little irritated at this conversation.
“I haven’t outgrown my crush on you.” He clarified.
Your eyes met his once again.
“Suguru, that’s mean.” You went to walk past him, but he held you still.
“I’m not being mean! I’m being serious, YN.” His eyes searched yours for understanding, maybe common ground, before you broke contact again.
“What is this? Did Satoru put you up to this? My mother? Did they pay you? Are you making fun of me?” Tears sprung to the corner of both your eyes. “Why are you doing this?”
His hands traveled from your waist to hold both sides of your face gently between his large hands.
“I’m not making fun of you. No one put me up to anything. Why would you think that?” He asked with genuine hurt in his voice.
“Come on, Suguru.” You scoffed. “You just said I look ridiculous. Plus, you’ve known me forever and you’ve known about my crush on you for years. You wait until right now to tell me after you just embarrassed me and insulted me?”
“I didn’t mean to. I didn’t mean that you look ridiculous, I just meant that you don’t look like you. You’re wearing something I know you hate because they force you into these situations and it makes me sick. I hate watching you be paraded around like a fucking prize to be won or bought. I didn’t like the thought of these men seeing you this way. I know what they would be thinking, and I can’t…” he took a breath. “ I said it wrong. I’m sorry.” He told you.
“Do you mean that?” You asked as the first tear escaped the confines of your eye.
“Yes.” He wiped the tear away with his thumb.
“What do you think?” You asked without looking up.
“What do you mean?” He asked.
“You said you know what those men would be thinking. What are you thinking when you see me like this?”
You heard him exhale a breath shakily. For a moment, you wondered if you had pushed things too far. Maybe, despite what he said, his feelings weren’t real, or that deep. You were about to make up some excuse to recall your question when his hand tilted your chin to look at him.
“The things that came to my mind when I saw you like this scare me.” He admitted.
“Why?” Your voice was a whisper as you lost yourself in his eyes.
“Because.” He swallowed. “Because that’s a line we could never come back from.”
“What if I didn’t want to ever come back from it?” Your hand slid up his chest to rest behind his neck.
“YN.” He whispered like your touch burned him.
“Sugu, if you’re serious, please…”
“Please what?” His forehead lowered to rest on yours.
“Suguru..” your mouth moved to find his, but he pulled back.
“I need you to say it, Baby.” His hand on your hip was squeezing your flesh desperately.
“I want you.” You whispered almost into his mouth. “I want you in every way I’m allowed to have you. Please.”
He was on you. His mouth captured yours as his hands lowered to pull you up and into his arms. One of his hands stayed on your thigh holding you up, the other was tangled in your hair pulling you closer and deeper into his kiss. Your hands wandered, but eventually found the buttons on his shirt and began undoing them causing him to smirk into the kiss. You pulled the shirt down his arms and he let you go long enough to shake it free of his body before his hands found you again.
“More.” You moaned into his mouth as the hand supporting your weight shifted from your thigh to your ass.
He pulled back to look at you more clearly.
“Are you sure? We don’t have to-“
“I’ve been waiting for you my whole life.” You stroked your fingers through his hair as you stared into the eyes you’d dreamed of since you were a child. “Please.” You said again as you rocked your hips forward causing him to groan at the feeling.
“If you change your mind…if you want to stop, you’ll tell me. Yes?” He looked as if he was barely holding onto control.
“Yes.” He exhaled the breath he must have been holding before you were thrown onto the bed. He locked the door before stripping himself of his pants and climbing over your body to kiss you again.
Your hands traced over his abs and biceps before lingering on the waistband of his boxers. He leaned up and pulled your legs back one at a time so he could free you of the heels. They hit the floor before his body found its way back over yours. His lips kissed over your neck and down to your breasts as if he was committing everything to memory. You sucked in a gasp when you felt him bite the fleshy part of your breast he could access without removing anything.
“I don’t ever want to see you in anything like this again. Unless we’re alone.” He kissed over the bite mark he had left.
He smirked before pushing your dress up your body. He pulled it over your head and tossed it onto the floor. He leaned back on his heels as his eyes took in your body. He stared so intensely you began to get self conscious. Your arms moved to cover your naked breasts, but Suguru caught them and pushed them away.
“Don’t hide from me. You’re beautiful.” He soothed.
Your gaze drifted down to the hardness still confined to his boxers. You could tell by the outline he was packing. You already knew this though. The two of you had known each other forever. There had been signs and things seen that shouldn’t have been from both of you. Now though, all you could think of was that it was going to be inside of you. How much would that hurt? You had only ever had sex once before. Has he? Surely he has. And surely he knew you weren’t experienced.
“You ok?” Suguru’s voice broke through your thoughts.
“Yes.” You assured him stroking your fingers over his face.
You couldn’t believe this was real. The man you had loved for so long loved you too. He was here right now about to make love to you. This was surreal.
His hands slid up your thighs and to your hips where the strings of your thong rested. His fingers looped through the strings and pulled slightly.
“Can I?” He asked softly.
You nodded. The scrap of material was pulled away and thrown to the side before you felt the heat of his stare.
“Don’t stare.” You said shyly.
“Can’t help it.” His voice was honest. “You’re beautiful everywhere.”
A blush covered your cheeks at his words. His fingers ran through the wetness between your legs causing a moan to escape you. He chuckled before inserting a finger into your entrance.
Suguru’s eyebrows furrowed slightly. “Look at me.”
“Are you a virgin?” He asked easing his finger out of your pussy.
“N-no.” You said suddenly feeling very vulnerable.
“It’s ok if you are. I just need to know.” He leaned down pressing a kiss to the bottom of your stomach.
“I’m not. But it was only once.” You told him.
“Ok. We’ll go slow.” He assured you.
“Suguru?” Your voice sounded quiet now, unsure of what you were about to say.
“Yes?” His mouth was hovering over your wetness as if he was breathing you in.
“I don’t want to go slow.” It was barely above a whisper, but it felt as if you screamed ‘fuck me hard’ from the rooftops.
Suguru stilled before glancing up at you.
“I have to.” He said. “It’ll hurt.”
“I don’t care!” You moaned as his finger re entered you.
“Sweetheart, you can barely take my finger.” He laughed.
“Please? I can’t take it anymore.” You squirmed, forcing his finger deeper.
“Fuck.” He cursed under his breath. “Baby, please. I’m trying to do this right.”
“Well, don’t! For one second can you please not think something through? I need you.” It was as if you could visibly see the restraint slip away.
“Look at me.” He demanded.
Your eyes glanced down to him where he remained inches from your pussy.
“If it hurts, or you change your mind, you tell me.” He said.
Suguru looked hesitant, but he made his way up your body to position himself at your entrance.
“Ok.” He warned you before pushing himself inside.
You both moaned at the feeling of the connection. The stretch of accommodation was painful, but there was pleasure just beneath the surface. Your leg hooked over his low back, pulling him forward to enter you more.
“Are….you…ok?” He asked between breaths.
“Are you?” You looked at him puzzled.
“You’re fucking tight.” He groaned.
“Too much for you?” You cocked your head.
He laughed slightly before pushing your knees back. “I’m going to make you regret that.”
Suguru began to move inside you causing you to see white, pure bliss. You could feel every inch of him, every vein, every pulse as he moved in and out of your warm, soaked walls. Quickly, his pace began to increase with his hips now slamming into your ass making a flesh on flesh sound erupt throughout the room. Your moans soon joined the mix feeling him get deeper and deeper inside you.
“Oh my god!” You moaned throwing your head back.
Suguru wasn’t fairing any better. His eyes were closed, mouth parted open as he hammered himself into you.
“You feel so good. So fucking good. Ohhhhh fuck squeeze me just like that.” Suguru babbled on top of you.
You noticed his eyes open and then fixate on something near your lower stomach. His eyes got bigger, then his thrusts slowed in speed, and increased in intensity.
“What are you doing?” You asked clawing at his forearms trying to pull him back down to you.
He didn’t respond. Instead, his hand let go of one of your legs before he pressed down on your lower stomach.
“Ah!” You squealed at the feeling.
“You feel me?” His eyes had gone dark. “That’s me in there.” He pushed down harder making you squirm.
“Fuck, Sugu. You’re so deep!” You cried.
He released the pressure, watching as the little bulge in your tummy reappeared before pressing down again. His hair had slipped free of its updo and now fell framing his face and water falling down to his shoulders. He was the prettiest man you’d ever seen.
“Huh?” You gasped as he applied more pressure. His hips began meeting your ass, but his hand remained pressing into the bulge he was creating.
“What?” You groaned as he hit a particularly tender spot inside you.
“No one else ever gets to have you like this. Only me.” He notified you.
“It’s only ever been you.” You pulled him down to be closer to you.
“You let someone else fuck you first.” He argued.
“That was different.” You told him as you tightened around his length making him moan. “I was….trying to get over you.”
“Did it work?” His breathing was ragged now.
His mouth attached itself to your neck, sucking and biting at the sensitive skin.
“I feel weird.” You gasped.
“What do you mean? Am I hurting you?” He asked searching your eyes for pain.
“No. Feels good.” You sighed.
“Are you going to cum?” He asked increasing his speed again.
“I don’t know!” You squirmed underneath him.
“Does it feel different than normal?” He was hitting a sweet spot making you want to explode with pleasure.
“Never” you breathed in sharply. “Done it.”
“You’ve never cum? I thought you’d had sex.” He questioned.
“I did. It sucked!” You grabbed at his body as the overwhelming feeling took over you.
“My poor baby.” He chuckled. “What about on your own?”
“This is the first orgasm you’ve ever had?” He asked.
“Yes!” You squeezed your eyes shut.
“You’re going to feel so good.” You felt his fingers find your clit, rubbing gentle circles as his thrusts continued their cruel pace.
“Oh my god!” The combined feeling of his fingers on your clit with his cock inside you unraveled in your belly. You came with a scream so loud Suguru covered your mouth with his hand. He kept fucking you through it though, and as soon as he was sure you had come down slightly from your high, he replaced his hand with his mouth.
“How was that, Angel?” He smiled pressing his face to yours.
“So good!” You moaned, still feeling the ecstasy of your release.
“Can I cum inside you?” He panted as his body began to thrust unevenly.
He came with a groan before collapsing on top of you. His head rested between your breasts as both of you tried to catch your breath.
“Insanely hot.” You finished for him.
Suguru’s head jerked up at the sound of someone banging on the locked door.
“Sugu!” Satoru’s voice called out.
You made eye contact, both suddenly very aware of the situation you were in.
“What?” Suguru called back to his best friend.
“You both came! Stop fucking off with whoever that is and come help me find my sister! You pissed her off!” Satoru yelled.
You covered your mouth with your hand to cover the laugh.
Suguru smiled. “Yeah, ok!” He responded.
You heard Satoru’s footsteps disappearing and you both laughed out loud at the situation.
“Oh my god, we can never tell him.” You said still laughing.
“We have to. Right?” Suguru said suddenly serious. “This….wasn’t just sex. Right?”
Your laughter suddenly stopped. You saw the seriousness in his expression and your heart melted to a puddle.
“Of course it wasn’t.” You agreed.
“Then we have to tell him.” He said.
“What? No way! That’s not fair.” Suguru complained.
“It so is. It’d be way more awkward for me to tell him than you.”
“I’m not telling my best friend I’m fucking his sister.” He told you.
“I figured you may use more tact.” You rolled your eyes.
“Ok, ok. We tell him together.” He leaned down to kiss you.
“Fine.” You agreed kissing him back. “Maybe we don’t tell him right away?”
Suguru looked relieved. “Secret sex could be hot.”
“Suguru!” Satoru screamed over the noise of the party still going on.
“Go! Before he breaks the door down!” You pushed at his chest.
He got up and threw his clothes on before kissing you one more time.
“Go.fucking.change.” He said between kisses.
“Careful.” He warned. “I like that.”
You laughed as he left the room, carefully shutting the door behind him blocking anyone’s view of the inside.
What a crazy night. Maybe Satoru’s parties wouldn’t be so bad from here on out. Not if they all end up like this.
Author’s Note: hey everyone! I’m supposed to be taking a break, but this was burning a hole in my brain. Hopefully it’s good! I haven’t quite been myself lately so this is somewhat out of the ordinary. I’m using this as a test to see if my page is back to normal! Let me know what you think! As always, thank you for reading :)
