practice or an excuse

Summary:

Sae Itoshi and Ryusei Shidou have been friends for years, but there’s always been unspoken sexual tension between the two.

Sae is good at hiding her feelings, whereas Shidou is quite literally the opposite.

But when Shidou asks Sae to help her ‘practice kissing’ before a date, Sae seems a little too willing to help out.

Notes:

Ok for context this is set in an au where sae and Shidou have know each other for ages and uhhhh idk what else to say im scared

But basically Shidou just pulls up to Sae’s house whenever she feels like it to hand out which is what’s happening at the start of this fic

(See the end of the work for more notes.)

Work Text:

Shidou aimlessly strolled into Sae’s house, whistling some random tune that had been stuck in her head all day.

She burst open the door to Sae’s room, seeing she was lying in bed, boredly scrolling through her phone.

Shidou’s grin widened approvingly as she noticed Sae was only wearing a small pair of sleep shorts paired with a pink lace bra.

“Shidou,” Sae greeted dryly, not needing to look up to see who had arrived.

“In the flesh,” Shidou beamed as she tossed her bag onto the bed, joining it soon after by practically pouncing on top of Sae.

Sae sighed, still not looking up from the screen as she ignored how Shidou’s face was now looming over her own.

“Off,” she commanded listlessly, finally shifting her gaze to the overnight bag which was now by her side.

“And why’d you bring that?”

“Sleepover,” Shidou said with a shrug, rolling off of Sae’s body, but staying close enough so that their sides were still firmly pressed against each other.

“We were long overdue,” she continued with a smirk, to which Sae shook her head.

“You came over last weekend. And the weekend before that, and the one before that and so on,” Sae mumbled as her thumb continued scrolling.

“Yeah yeah details details,” Sae dismissed with a vague wave of her hand, “Let’s talk about something else.”

Sae scoffed, unconvinced, “Like what?”

Shidou’s tongue dragged across her teeth, as if she had been waiting for the question.

“Like your outfit choice.”

Her hand snaked over to give one of Sae’s tits a squeeze for emphasis.

Sae clicked her tongue as she swatted off Shidou’s hand, “Careful or I’ll put a top on.”

Shidou pouted, propping her chin on Sae’s nearest shoulder to peer in at her phone screen, “Can’t have that,” she murmured, deciding to rest her palm on Sae’s stomach instead.

Sae rolled her eyes, but allowed Shidou’s touch to settle nonetheless.

Shidou turned her face to view Sae’s, squinting slightly as if she was intensively analyzing something.

“What now?” Sae grumbled.

“Did you do something new with your eyelashes? They’re even longer than usual,” Shidou observed, reaching up a finger to brush along the ends.

“New mascara,” Sae stated, her lashes brushing off of Shidou’s finger tip as she blinked.

“Mm. It’s pretty,” Shidou retorted, before she let out an obnoxiously loud yawn, splaying out her limbs like she was actively trying to take up as much room as possible.

“I got a date tomorrow,” Shidou said as she propped her arm above her head, elbow sticking in the air.

Sae finally turned her phone off, placing it face down atop of the sheets as she settled further into the bed.

“With who?”

“That guy in our science. Y’know the one with all the piercings?”

Sae’s nose slightly rustled in distaste.

“He’s an idiot. He’s failing five out of his six classes.”

“Well that’s irrelevant. Apparently idiot boy’s got, like, an eight-incher.”

Sae raised an unimpressed eyebrow at the statement.

“I’m not convinced.”

“Oh yeah? Wanna come and see for yourself then? I’m sure he wouldn’t mind a third,” Shidou teased, reaching out to poke Sae’s nearest side.

Sae barely flinched at the prod, already too used to Shidou’s antics.

“Yeah fuck off,” she scorned, but there was no real heat behind it.

Shidou shifted her position, laying her head atop of Sae’s bare stomach.

Sae let out a groan at the change of position, but didn’t bother to swat Shidou off.

Shidou drew lackadaisical patterns atop of Sae’s collar bone.

“Y’know lashes, it's been a while since I’ve kissed someone… and I wouldn’t wanna fuck up and embarrass myself tomorrow,” she purred, finger tip still running up and down.

Sae blinked at her with half lidded eyes, “Thought you fucked that chick with the curly hair last week, stop lying.”

Shidou gasped in mock offence, “There was no kissing involved! And for the record we didn’t fuck fuck, she just ate me out.”

Sae gave an unimpressed hum of acknowledgement and Shidou slowly raised an smug eyebrow.

“Why’re you making assumptions about my sex life in the first place, hm? You like picturing me getting laid?”

Sae let out an amused exhale through her nose, which probably could’ve been considered a breath of a laugh.

“No way. Don’t flatter yourself,” Sae drew her gaze downward, eyes slowly dragging across Shidou’s features.

“I call bullshit,” Shidou drawled lips twitching into a smirk.

“Why’s that?”

“I’ve known you for years. I can tell when you're lying,” Shidou sang, finger traveling up the side of Sae’s neck until it landed on her jawline.

Sae huffed, face staying stoic as she looked back at Shidou through narrowed eyes.

Momentary silence set between them before Shidou broke it with her usual grin.

“So about that kiss…”

Sae rolled her eyes, “I never agreed to a kiss.”

“Woah woah, never said you did pretty girl,” Shidou murmured, twirling the hair by Sae’s ears in small circles.

“Yeah well you implied it.”

Shidou’s grin only seemed to widen at the accusation, “How so?”

“With your tone.”

“This tone?” Shidou asked, using the same one as before as she raised her head off of Sae’s stomach.

Sae breathed out through her nose, “You’re an idiot.”

“An idiot who you think’s hot,” Shidou argued, her figure looming over Sae’s.

“Again, you’re just putting words in my mouth,” Sae droned, seemingly unbothered by the sudden proximity of Shidou’s face to her own.

“So how bout I put my tongue in there instead?”

Sae’s brows furrowed at the latter’s words, “Your flirting’s cliche. It’s a wonder how you get so much play.”

Shidou’s smug expression completely contorted into one of amusement as she burst into laughter at Sae’s bluntness.

“Holy fuck. I forget how funny you are sometimes lashes.”

“It wasn’t a joke.”

“I know. That’s why it was funny.”

Shidou’s body was still shaking with laughter, the ends of her long hair brushing over Sae’s skin.

Sae’s studied how Shidou’s eyes crinkled when she laughed, her own expression hinting she was weighing her options.

“How bad do you need to practice kissing?”

Shidou blinked, caught off guard by Sae’s sudden question.

Her laughter stopped out of shock, although a flicker of amusement was still seen behind her eyes.

A smirk crept back upon her face as she tucked a strand of Sae’s hair behind her ear.

“Really really bad,” Shidou exaggerated insistently, cupping the edge of Sae’s face.

Sae gave a flat exhale, “You better impress me.”

“Oh I solemnly fucking swear I will Sae-chan,” Shidou whispered, her lips brushing against Sae’s as she spoke.

“Do your worst.”

Shidou gave Sae one last shit-eating grin, before pulling her face against her own, their lips colliding.

Sae reached up, placing one hand on Shidou’s arm while her other balanced at the nape of her neck.

Shidou’s hand gravitated to the side, her fingers burying within the latter’s soft hair, using the grip to bring her even closer.

Shidou parted Sae’s lips with her tongue before entering.

Her free hand balanced on the curve of Sae’s waist, fingers splaying out to touch as much skin as she could.

Their tongues hungrily swirled around each other’s in perfect synchronisation.

Saliva combined as Shidou shoved her tongue as deep as she could into Sae’s mouth.

Shidou’s thumb slowly, almost teasingly, stroked up and down Sae’s stomach.

The softness of the action contradicted the harsh kiss, causing it to send shivers throughout Sae’s body.

Shidou dragged out Sae’s top lip, both of them taking a mutual breath before diving back in again.

Sae sucked on Shidou’s bottom lip as Shidou’s tongue lapped over Sae’s.

Shidou dropped her body down so their torsos were touching.

Shidou’s hand crawled up, slipping in between where their breasts were touching.

She curled his fingers, squeezing the soft flesh beneath her grip.

A soft moan accidentally escaped Sae’s lips, the sound vibrating within both of their mouths.

Sae’s hand moved from Shidou’s arm over to her back, sliding inside the thin material of her tank top, dragging a lazy finger tip up her spine.

She leaned her head up to get closer to the kiss, one of her legs automatically hooking over Shidou’s hips.

Shidou groaned approvingly at the action, sliding her knee up the bed to press into Sae’s exposed wetness.

And from the way Sae pulled Shidou closer to herself, combined with the way Shidou’s fingers tangled deeper and deeper into Sae’s hair, it was clear this was never really just ‘practice’.

More so an excuse.

Sae rolled her hips against Shidou’s knee in a desperate seek of friction.

Shidou dragged her knee sideways to scoot away the material of her shorts, knee now making direct contact with her soaked panties.

Sae could feel Shidou’s lips upturn into a triumphant smirk against her own.

Shidou tilted back, just enough to break the kiss, but not enough to fully part their faces.

“Hah,” She breathed out in an amused, silent laugh, “You’re so wet,” she taunted proudly.

“No shit I’m wet, I haven’t gotten laid in like a month now shut up and kiss me more,” Sae snapped, most likely irritable due to how flustered she was.

Although her hips kept grinding despite her angry words.

“Aw,” Shidou gushed arrogantly, “As you wish hot stuff.”

Shidou captured Sae’s lips again, pressing her knee harder against Sae’s pussy as she did so.

The combined sensations made Sae whine louder into her mouth.

Shidou’s hand dragged away from Sae’s tit, only to slide her hand right back, only this time from underneath the wire.

Shidou let out a muffled noise of approval as she felt Sae’s bare skin beneath her hand.

Her thumb slid over to the peak of her hard nipple, rubbing it in small circles while the rest of her hand clawed at her cleavage.

Sae’s leg tightened around Shidou’s waist in approval, creating a new angle and deepening the touch of the latter’s knee.

Shidou brought her lips off of Sae’s, only to trail an array of open mouthed kisses along her neck.

Sae’s eyes remained closed as her grip tightened around the back of Shidou’s neck.

Shidou’s trail of kisses reached the crook of Sae, her teeth sinking into the sensitive skin and making Sae hiss.

Shidou chuckled at the reaction, gently sucking in the area of impact before nipping her teeth up until she reached Sae’s jawline.

Shidou dragged the tip of her tongue along Sae’s jawline until she reached her ear.

She bit down on Sae’s earlobe, lightly pinching her nipple at the same time.

The combined actions made Sae yelp and Shidou smile.

“Shhh,” she cooed mockingly into her ear, abruptly dragging her knee away from Sae’s grinding hips.

Sae looked at Shidou, confused, as her hips unwillingly moved forward against nothing.

“Aww don’t get pouty baby girl,” Shidou tutted, batting her eyelashes in mock innocence as she gave Sae’s boob one last squeeze before removing her hand completely.

“I’m gonna give you something even better, kay?” Shidou drawled, hand creeping down Sae’s torso and arriving at the waistband of her shorts.

She dragged her finger along the inseam, watching Sae’s expression for any more falters.

“All ya gotta do is say please.”

Sae scoffed at the request, though it sounded a little more strained than usual.

“Fuck off.”

“So we’re being bratty now are we?” Shidou mumbled, her hand releasing Sae’s hair to grab the other side of her waist.

“C’mon it’s just one word.”

Sae tried to sigh, but nothing came out, all her focus being on the heartbeat she could feel in her clit.

She clicked her tongue against the roof of her mouth, “Please,” she said, ensuring her voice was even more monotone than usual.

“Nah you gotta say it like you mean it.”

“Shidou,” Sae warned, tone implying she clearly didn’t have the patience for games.

Shidou sighed dramatically, “Fine,” she grumbled, her tongue gliding from in between Sae’s tits all the way down to where her shorts hung on her hips.

Although Shidou made no move to tug them down just yet as she looked up at Sae.

“So tell me lashes, what kinda panties have you got on,” she purred, one hand crawling up her thigh with excruciatingly light pressure.

“White?” Shidou wondered, her hand finally settling on Sae’s inner thigh.

Sae shook her head, “No.”

Shidou hummed thoughtfully, “Those cute little black ones you bought when we went shopping?”

A finger passed the material that was covering Sae’s crotch, gently grazing along the soaked lace which lay underneath.

“Wrong again.”

Sae tried to come across as deadpan, but the way her breath hitched as Shidou’s finger made contact gave her away.

“Oh I got it,” Shidou stated confidently, “They match your bra right?”

She stroked up again, harder this time, yet still not hard enough for Sae to feel any real pleasure.

“Third strike. You’re out,” Sae said below her breath, clit throbbing harder as Shidou’s finger settled above it, not pressing down, just remaining still.

“Dang. That mean I’m not allowed eat your pussy?”

Shidou looked up at Sae slyly as her other hand fully gripped the waistband of Sae’s shorts, ready to tug them down.

“No. Just means you have to eat it better than you were initially going to.”

Shidou practically beamed at the answer, her hand tugging Sae’s shorts down to her ankles to view the true colour of her panties.

“Hot pink huh?” Shidou questioned, hungry eyes scanning the underwear with great intrigue.

Her eyes narrowed in mock suspicion as she glanced up at Sae, “You put on my favourite colour on purpose or is this a coincidence?”

Her finger trailed the inseam of Sae’s thong, her touch tickling Sae’s soft skin.

“Less talking,” Sae murmured as she spread her legs further apart.

Shidou giggled at the command, deciding she was finally done playing games as she tugged the underwear to the side.

She leaned forward, dragging her tongue across Sae’s bare slit.

Sae’s finger dug into the sheets on either side. The rustling sound made Shidou smirk cockily as her tongue flicked over Sae’s pulsating clit.

A hand balanced itself on either one of Sae’s thighs, dragging her closer toward Shidou’s face.

Shidou’s tongue circled around Sae’s hole before she resumed her lapping around her folds.

She played around with Sae’s juices, dragging them back and forth across her clit.

She sucked Sae’s ball of cells into her mouth, Sae let out a low moan, senses all overwhelmed with pleasure.

Shidou laughed against Sae’s wetness, the feeling of her breath against the sensitive area making Sae whimper, fingernails practically indenting the mattress.

One of Shidou’s hands trailed up Sae’s thigh, her tongue still swirling around her nub.

A finger traced the area surrounding Sae’s hole, not entering just yet.

Sae made a poor attempt at scooting closer to Shidou’s finger.

Shidou grinned, delving her tongue back into Sae’s wet flaps, trying her best to absorb as much of the liquid as she could.

Two fingers pushed slowly into Sae.

Too slowly.

“Please,” Sae whispered weakly.

Shidou looked up from where she lay, eyes marked in triumph.

“Oh so the pretty girl can beg.”

“Fuck off,” Sae ran one hand through her hair impatiently, “Just fucking do it already.”

“So demanding,” Shidou drawled, pushing her fingers into Sae in one fluid motion.

Sae yelped at the sudden impact, thighs already beginning to tremble as Shidou pumped her fingers in and out of her aching hole.

“More. More, faster,” Sae groaned, knuckles turning white from her grip on the sheets.

Shidou released Sae’s clit with a wet pop to speak.

“More already? But you’re practically already screaming Sae-chan,” she jeered, amused, but sped up the pace nonetheless.

Sae cried out at the newfound speed, hips moving down to meet each thrust.

“You’re louder than I thought you’d be,” Shidou thought aloud, although she seemed extremely pleased with the fact she was.

Shidou delved even deeper forward, back arching due to her position of being on all fours.

Sae looked up at how Shidou’s ass was now in perfect eyeline, her low waisted jeans crawling down and revealing the string of a leopard print thong.

Sae felt the pulse of her clit increase even more at the sight.

“Harder.”

“Harder?” Shidou questioned, eyebrow mockingly quirked, not speeding up just yet.

“Harder,” Sae repeated, more insistently this time.

Shidou shrugged, fingers pounding at an even more brutal, almost punishing, pace, “Okay but don’t get mad at me when you’re sore later,” Shidou sang with a grin as she lapped at Sae’s lips.

Shidou moved her thumb up so that she could rub Sae’s clit while simultaneously flicking her tongue at its edges.

“Holy fuck,” Sae spluttered as her back arched further, giving Shidou a deeper angle.

Sae’s head fell back as all of the senses fully overwhelmed her body.

“So… so good,” Sae stuttered, biting down hard on her lip to reduce any noise.

Shidou shook her head as her eyes flicked up, “None of that,” she demanded, drawing an imaginary circle around how Sae was biting down.

“I wanna hear,” she protested, voice slightly muffled from her mouth being buried within Sae’s lips.

Sae reluctantly unclasped her teeth, the earlier train of moans returning.

Sae winked up at her in approval, eyes narrowed smugly.

“That’s more like it,” she praised before fully diving back into Sae’s pussy, swirling her tongue round the flaps.

Sae hit her palm against the mattress as Shidou’s fingers continuously brushed over her g-spot.

“Gonna come,” Sae groaned, toes curling as she struggled to breath.

Shidou’s eyes were flooded with pride as she sucked in Sae’s throbbing clit one last time, fingers moving in circular motions around Sae’s inner walls.

Sae let out one last incomprehensible noise before she let go.

Squirt sprayed all over Shidou’s face, making her grin widely as she let go of Sae’s nub.

She pumped her fingers a few more times, before she finally pulled them out.

Sae’s chest heaved as she panted for breath, body collapsing against the bed.

Shidou stilled in her position, droplets of squirt still decorating her face as she watched Sae recover.

“Best sleepover ever.”

“God you’re annoying.”
