A/N: Was originally intending to upload Ch10 of Halo today, but due to time constraints I saw it best to delay it by a week to allow for more breathing room. Apologies to anyone expecting that chapter, considering the multiple delays already, but it is what it is.

That aside, do enjoy a shortish Allen lewd - set in a school AU~

Locked In Here Together

School was always a pretty boring place, for Allen.

That wasn't to say she disliked it. She enjoyed the experience, of going from class to class and learning new things – even if half of them were boring and pointless – she liked hanging out with friends at lunch and meeting new friends, and she really liked some particular classes. Amongst them, being gym class.

Be it basic exercises to jogging around the football pitch to basketball, she was all for it – and as such she was a regular at after-school gym clubs, particularly basketball. Though she didn't really plan on becoming a professional it was a fun past-time for her and she got to hang out with a lot of friends during it... which, made it all the more disappointing when she had to cut her involvement short early due to a doctor's appointment later in the day.

''Haah~''

Allen's displeased sigh could be heard easily within the female changing rooms as the dark-haired student walked inside. Clad in a white gym top with short sleeves and a pair of blue shorts Allen strolled across the rectangular room to where her locker was, twisting the knob to the right code before clicking it open. Lacking any shelves it was deeper than regular lockers, allowing her clothes to be hung on coat hangers instead of being stuffed in blindly... though, due to being in a rush, she'd just ended up stuffing things at the foot of her locker anyway.

Unbothered Allen grasped the hem of her gym t-shirt and pulled it up and over her head, the material tugging on her hair briefly before it went up and over her head, allowing her to toss it onto the bench behind her. Nimble fingers then went to her grey sports bra, curling under it and tugging it up, breathing a sigh of relief as she pulled it up and over her head too, letting her boobs breathe freely. She'd never been one for sporty bras, preferring regular bras; less constrictive.

''Maybe I've grown again...'' Idly Allen murmured.

''Probably~''

Allen squeaked in shock as a pair of hands came up from behind, grabbing her boobs and squeezing. ''H-Hey!''

Swatting the hands away she whirled around to face her molester – only to relax as she laid eyes on the familiar face of her boyfriend. ''Geez... thought you were that pervy teacher for a second there, don't do that!''

''Sorry, sorry.'' With an unrepentant grin the young man chuckled, hands held up in surrender. ''Couldn't resist. And my comment still stands, by the way.''

''Perv~'' Allen stuck her tongue out at him. ''What're you doing here anyway? This is the girls' changing room, y'know. You weren't perving on other girls were ya~?''

''Nah, just waitin' for you.'' With a smile and wiggle of his brows he approached her, hands settling on her hips. ''Hid in the locker behind me. If someone else came in with you I was just planning on waiting it out so I could sneak out before anyone noticed.''

Allen rolled her eyes at that, leaning in and pecking her boyfriend on the lips. It had been several months since they'd started dating and acts like this weren't uncommon; his perversity was well-known and she wasn't entirely against it, not least because of how harmless it was. The few times it was more intimate he joked less; mindful of her own feelings and, though he hid it behind a joking façade, he was caring and attentive of her.

''Still.'' Allen bopped him on the nose. ''You can't be here. You'll get in trouble – again – if the teacher catches you here.''

''C'mon, I just wanted to see you.'' Kissing her cheek he openly looked at her chest. ''The fact I get to see your boobs is a nice bonus though.''

Another bop to his nose. ''Perv~''

Their eyes stared into each other's, a momentary silence hanging over them... before as one both broke out into snickers and giggles. Both knew she didn't really mind him seeing her naked, and both knew he was just too impatient to wait outside for her to visit. Thus with a more coy smile Allen slid an arm under her bust and pushed it up, wiggling her brows almost challengingly as she gave him a good look at her tits; small but plump and tipped with perky nipples.

Her boyfriend indulged in that challenge, claiming her lips in a sudden, surprise kiss – muffling Allen's aroused moan. Both of his hands abandoned her hips and groped her breasts gladly, fingers sinking into her soft, squishy tits and hefting them about, his earnest touch sending a shiver through Allen's form. His thumbs slid along her boobs until he found her nipples and rubbed them about, the teasing touch making her groan with want, both fully aware of how sensitive her nipples were. He'd exploited that fact more than once.

And clearly intended to do it again – diving down and taking her right nipple into his mouth, sucking upon it.

''Mm~!'' Allen couldn't contain her soft mewl – her lips pursed to mute it but failing to silence it completely. ''H-Hey... not there...''

Her boyfriend merely replied by sucking more, his tongue lashing at her perky nipple before stroking wet circles around it, earning a moan of pleasure from the dark-haired student. Briefly his lips parted from her tit but that lasted only a second, giving him time to lean over and take her other nipple into his mouth, sucking that one off whilst his thumb played with her other, now-wet nipples, rubbing it about with hungry passion. Allen shivered at his touch and weaved her fingers into his hair, pulling him against her boobs and encouraging him to keep doing it, her breathing getting heavier and making her boobs push against his face.

Until with a wet exhale he popped his lips off her tit and leaned back, both hands sliding down to her waist – and yanking her gym shorts down. Allen yelped in surprise, her cheeks darkening to a burning red hue, but any words she had melted on her tongue as he shoved his hand into her underwear, fingers touching her sex. The sensation alone sent shivers travelling through Allen's body, a meeker moan escaping her lips before he claimed them in another kiss, one hand grabbing her ass almost possessively.

''Mn, hey...'' Allen breathed, pulling back from the kiss to pout only for him to kiss her again – pushing two fingers inside of her. ''Ah~''

Her boyfriend relished her moans, pushing his two digits deep into her womanhood and curling them slightly as he stated pumping them in-and-out, the sensation coaxing more stiff groans from Allen's lips, audible only between kisses. He fingered her slowly but with his saliva cooling on her nipples it felt all the more erotic, her breathing short and fast as he got her off, his kisses taking her breath away. Her walls clenched extra tight when he teasingly flicked her clit, the short but sweet moan he coaxed out of her only encouraging him to do it again.

And he would've done so... had they not heard the sound of the hallway door thudding open, followed by a slew of voices gradually getting louder. The rest of her team was coming back to get changed. The thought struck them at the same time, both freezing up in a dangerously compromising position. The only way out of the room was the door – the windows were too small and not openable. The only way her boyfriend would get out uncaught... would be to hide in the locker.

''Q-Quick!'' Allen hurriedly whispered, shivering as he yanked his fingers out of her.

Acutely aware of how little time they had Allen bent down and snatched up her top and bra whilst he got in the locker behind, her other hand yanking her shorts back up her waist – when her boyfriend grabbed her waist and pulled her into the locker as well. Allen squeaked in surprise but resisting would look weird so she didn't, face hot as her boyfriend pressed himself against one wall of the locker and got her to stand in front of him, his other hand yanking the locker door shut.

And not a second too soon. With a hiss of rubber the changing room door opened up, the voices of her friends and teammates filling the changing room as they filled in one by one, casually walking over to their lockers and going about getting changed. Unlike her though none of them were in a real rush, some standing around and chatting whilst others were more languidly undressing, taking their time with it.

Allen blushed. They had no choice but to stay in there now; it would be weird if she suddenly came out of the locker for no reason, even assuming nobody saw her boyfriend in there with her.

Glancing back at her boyfriend in question Allen twitched as she noticed him also watching her friends – and quite apparently enjoying the sight of them changing. From Hanazuki peeling her underwear down and giving them a good look at her peachy butt to Baltimore taking her gym shirt off and pulling her school shirt on, doing it up button by button; her boyfriend saw it all. And liked it, she realised; feeling his swelling cock press against her ass.

''Myn...'' Pouting Allen pressed her butt back against his crotch, drawing his gaze. ''Don't stare at them.''

Her voice was barely a whisper; the low drone of the ventilation system helping mute her quiet voice. Her boyfriend smiled apologetically at her and obliged... but now he was looking at her. Topless and with her shorts haphazardly yanked up her hips, her breathing fast and her face flushed, she looked like an attractive mess. One that he wanted to play with more – something he proved with his hands, one sliding up to her left breast whilst his other dropped into her panties, two fingers pushing inside her wet, dripping pussy without hesitation.

''M-Mn!'' Quietly Allen whimpered, shuddering as he started fingering her again. ''H-Hey...''

Her boyfriend smirked, leaning in and kissing the back of her neck, earning a shaky exhale from Allen. With only three slits for viewing a minimal amount of light spilled into the locker, making it all the more erotic as his digits pumped into her wetness, rubbing and stroking her in ways that her own fingers never could, teasing out stiff gasps and stilted whimpers, her voice carefully kept quiet lest she alert her friends and get them caught. The hand groping her breast made it that much harder though, two of his fingers pinching her nipple and tweaking it lightly.

And it was getting to her. Every little curl of his digits, the twists and scissors, all of it spiked pleasure through her needy wet sex and made her swallow moan after moan, her head getting fuzzy. The risk of being caught left her breathing faster, chest heaving into his groping hand and adrenaline rushing through her veins, mortified at the possibility yet shamefully thrilled by it too.

Combined with his prior fingering and Allen found herself rapidly nearing her limit, her walls clamping tighter around his teasing fingers, one hand clasping over her mouth to hide her moans – when he ripped that hand away, tilted her head, and kissed her.

''Mmph-!'' Allen's muffled moan preluded her spasming, writhing climax; feverishly humping his hand mid-climax, the pleasure washing over her and briefly leaving her mind white.

Laughter from someone outside the locker brought her out of her high though, her body tensing sharply before she relaxed; breaking off the kiss with a laboured breath. Her own panting was the only thing she could hear for a moment, the sounds of her teammates chatting away going ignored. Her attention shifted south however as she felt his clothed cock twitch against her butt, making Allen bite her bottom lip and peek out the three-slit window, worried about being caught... but wanting more so bad.

After a short delay she made her decision, both hands going down to her shorts and shoving them down. Her panties came down with them and left her standing practically naked in front of her boyfriend, his eyes running down her bare back and landing on her ass, one hand palming it before hurriedly undoing the front button of his pants, a quick unzip letting them shove them down alongside his boxers, letting him slap his erect cock against her ass. Rocking his hips he grinded it on her ass and she helped with that, pushing her butt back and feeling him throb between her cheeks... until soon he aimed lower, the underside of his cock sliding along her pussy several times.

Allen leaned forwards as much as the cramped space of the locker would allow. ''Put it in...''

Her boyfriend obliged, guiding his cock down – and Allen clasped a hand over her mouth to hide her gasp as he finally slipped inside. Readily she pushed her ass back, shuddering in silent ecstasy as she felt his cock smoothly spear into her wet pussy, spreading her sensitive inner walls apart bit by bit until he was fully inside her, throbbing strongly against her walls. The erotic feeling briefly left her dazed, almost in bliss just from having his dick inside her.

However conversation outside stirred her from her daze, cheeks darkening as she remembered where they were. With rosy cheeks the dark-haired student leaned forwards slightly, lifting herself off of her boyfriend's cock before impaling herself back onto him, quelling a moan before it could leave her throat. He did the same, holding her waist and quietly hissing as she worked her waist, her pussy swallowing his sizeable shaft up with every slow roll of her hips.

''Hah...'' He leaned in, kissing her ear. ''You're tighter than usual.''

''D-Don't say that...'' Allen breathed back, biting her bottom lip.

In response her boyfriend cupped her cheek and tilted her head, allowing them to kiss her over her shoulder – the lip-lock helping mute their mutual groans as they kept fucking. Her classmates remained blissfully blind to the act, continuing to undress or put on their uniforms, entirely unaware of Allen getting dicked just a few feet away; her short, stilted grunts inaudible over the groan and thrum of the ventilation system.

His other hand wasn't idle either, sliding up her belly and groping her right breast from below, fondling it. Allen shivered at that and pulled back from the kiss, her breathing short and heavy as she felt him handle her tit – occasionally squeezing or jiggling it about. Naturally his thumb teased her nipple, flicking the sensitive nub about and making her tighten around his pulsing cock, earning a mutual grunt from them both, barely able to keep their voices to themselves.

''Ah... a-ahh... ah...'' Softly panting and moaning Allen leaned in for another kiss, making out with her boyfriend.

Releasing her cheek her boyfriend slid his other hand up to her other breast, holding them both and pinching her nipples as he pounded her; the ensuing pleasure taking her breath away and leaving her tight as a vice around him. Groaning into her mouth he pinched her nipples more, his hips bucking forwards in short, hurried thrusts, driving him deep inside Allen's pussy and melting her mind, her own hips pushing her back onto his cock with equal haste.

A loud thud echoed as several people opened the changing room door and left, letting it close behind them. Though people were still in the room the lower number gave her boyfriend the confidence to move faster, his cock entering her with moan-inducing speed, forcing her to break off the kiss and cover her mouth lest a moan slip out unbidden. The dark-haired student rested her head against the opposite wall of the locker at the thought, trying her best to keep her voice down even as he hit her from the back, his cock pumping smoothly inside of her sex.

Allen screwed her eyes shut, feeling him hit a good spot deep inside her over and over again, battering against it like a ram. ''A-Ah... almost...''

Thankfully nobody heard her, nor her boyfriend as he groaned; a bout of laughter muffling it. Desperately she begged for her friends to leave the room before she came but couldn't hold on for long enough; her walls clenching ever-tighter around her boyfriend's dick as he drove it into her, feeling heat spread through her pelvic muscles and melt her mind with the seizing, bursting want, her toes curling and her breath held in her throat-

''Mn-!''

-until with a short, sharp grunt her boyfriend came inside her, unable to pull out within the locker's cramped space. The sudden warmth that flooded her sex pushed Allen over the edge, a soundless spasm seizing through her whole body and making her clamp tightly around him, squeezing out thick ropes of semen that splattered inside her in short bursts; his continued thrusts smearing his milk into her walls, her mind as white as his seed.

''M-Mmphaah...'' Allen felt like she was melting, shuddering and shivering as he filled her with his seed – the sensation a novel one.

Normally he pulled out and came on her stomach or back, or face if possible, but given the cramped space of the locker that wasn't possible.

Coming back to full coherency Allen dimly heard the rest of her teammates gradually leaving the room one by one, until with a final thud the changing room door shut and silence fell over the room. Only then, as she heard her friends leave the hallway outside, did Allen budge the locker open and awkwardly shimmy out, moaning as her boyfriend's soft cock slipped out of her.

''Hah... that was...'' Allen panted, awkwardly yanking her underwear back up and stumbling out of her shorts. ''Dang it, I'll... probably be late to my appointment now...''

''Sorry.'' Her boyfriend chuckled breathlessly, kissing her on the back. ''I'll buy you ice cream tomorrow after school. Sound good?''

''Heh. Fair enough.'' Allen cracked a grin. ''You better run now by the way, before the PE teacher finds you running out of the changing room halls for no reason~''

Her boyfriend winced at the thought and agreement, waiting long enough to give her a proper goodbye kiss before fleeing – Allen's giggle left in his wake.

And unseen by him her hand came to rest on her groin, smiling timidly as she felt his warmth deep inside of her.

'Heh... feels kinda nice.'
