A/N: Remember how with Isuzu's Halloween fic that I mentioned about making one of Isuzu in her Christtmas skin? Welp, this is it.

Cosy Night

The slow crackling of the fire was always a pleasant sound for the Commander.

The gentle crackling, the pop and spitting of the wood burning up, the brief roar as the flames climbed before settling back down; all of it cycled around in an endless routine as he kept adding more logs to the fire, keeping it burning strong for hours on end.

With a smile the Commander leaned back slightly on his arms, staring into the warm fireplace in front of him. The living room light was off and bathed the room in darkness, waving shadows whipping across the carpet around him as the flames moved.

Winter was still going strong, the frost crawling up the window pane to his left telling of that, but Christmas had just passed a matter of days ago; leaving him with mercifully little to do. He wouldn't quite call it a 'break', but it was as close as he could get to one.

Soft footfalls padded behind him. ''Commander...''

He smiled lightly, tilting his head back and spotting his housemate and girlfriend, Isuzu. Ever since that night on Halloween when they got together and started dating they could be seen together, and after just a few weeks of dating Isuzu moved into his house so she could spend more time with him. Over time she lost some of her innate nervousness, becoming a slightly more confident, more mature version of herself. Though that didn't stop her from turning into a whimpering, trembling mess when a spider landed on her arm and scared the life out of her. And deafened him in the process with her shrill scream.

Isuzu's growing confidence could be seen in her new outfit as well; one she had picked out halfway through December. A casual black camisole hung from a pair of thin straps looped around her neck, a loose cream sweater thrown on over it. One long black stocking hugged her left leg whilst her other had slipped down to her shin, the mismatched design only adding to her appeal – and when she moved her sweater shifted, revealing she wasn't wearing a skirt or shorts underneath, but instead just some black side-tie panties.

Smiling at him Isuzu approached, lowering down and sitting next to him, happily leaning against his side. The Commander wrapped an arm around her slim side, humming as he just enjoyed the shared warmth of their bodies. With all the other house lights off and no other sound to be heard, and it made for a very romantic moment.

''Mm...'' Isuzu slipped her left hand over, laying it over his leg. ''I'm kinda glad Christmas is over now... it was so exhausting~''

''Yeah.'' The Commander agreed, chuckling. Thankfully he didn't have to do things like cooking or decorating for Christmas itself, but organising everything was taxing on the mind. ''Is Nagara and Abukuma still coming over on New Years to watch the fireworks with the others?''

Isuzu hummed an agreement. ''Yes... I've got all the stuff prepared for it, so we don't have to worry about it.''

With a smile he pecked her on the cheek as thanks, bringing a cute pink blush to Isuzu's cheeks. Since both had been so busy neither had much of a chance to just sit and relax with each other, both of them hitting the sack as soon as they were finished. But now that they had several days until New Years Eve, and they could afford to have some fun.

Something he subtly suggested by kissing her neck. Isuzu moaned softly and lolled her head to the right, exposing more of her slim neck to him and enticing him to trail kisses along her jugular, relishing the cute noises she made. His right hand held onto her side tighter and his left hand curved around, resting atop her left and intertwining his fingers with hers, holding her hand. She quivered at the simple gesture of affection, mewling through pursed lips as he teased her.

''I like your outfit.'' The Commander whispered into her ear, smooching it and making her whimper. ''Have I told you that?''

Isuzu just blushed and smiled demurely, tilting her head towards him. He met her halfway, his rougher lips meshing against her smaller softer ones in a kiss, the arousing smooch filling the air. Mutual exhales escaped their lips in the brief moments they pulled back, both reigniting the kiss as soon as they could, the gentle tempo of their kissing session only making it feel more erotic, and enticing Isuzu to be a bit more bold.

The cruiser slid her left hand along his leg, soon resting it over his crotch. He shivered at the feeling and guided her hand to the zipper, feeling her fingers curl in and pinch the zipper, pulling it down with a low, disjointed buzz, tugging it harder when it got stuck a couple of times. The moment she got it down she pushed her hand in the hole, fishing about in blind embarrassment before she found his boxer buttons, undoing them and allowing her to tug his cock out into the open.

''Mn...'' Isuzu blushed a cute crimson hue as she felt his warm cock, her lithe fingers curled around it. ''C-Commander- ah~''

A soft moan worked its way out of Isuzu's throat as he returned the favour, his right hand leaving her side and sliding down. It was trivial to dip his hand under the waistband of her thin panties, cupping her pussy and stroking her folds with growing lust, With a cute whimper Isuzu got him back by stroking his cock, sliding up slightly before moving back down. Her grip was gentle and her palm soft, making it feel even better for him, her slow strokes eliciting a low groan from his throat.

Their lips kept meshing together as they got each other off, his fingers boldly pushing into her smooth slit and eliciting a soft moan from Isuzu. Her hot insides tightened around his intruding fingers, her fleshy inner walls conforming to the shape of his digits when she tensed up – prompting Isuzu to pay him back by jerking him off more, her wrist twisting slightly as she moved, sending tingling want creeping up his cock.

''Mmph~'' The Commander groaned into her mouth, pumping his fingers into her sex and adding a third; earning a muted mewl form Isuzu as her toes curled.

The crackling of the fireplace did little to muffle their mutual moans and groans, his fingers sliding into her womanhood and her hand stroking up his cock. It wasn't the first time they had done it but the sheer novelty of the sensation made it erotic beyond words, his dick rock-hard from her quick strokes – his pleasure only growing when she squeezed his dick lightly, her fingers shifting over his cock as she adjusted her grip.

Until Isuzu suddenly got an idea, pausing. She shifted uncertainly and pulled back from the kiss, sparing him an embarrassed look. ''Commander... could we do 'that' thing, again...?''

The Commander flushed lightly but was all too happy to comply, delighted that she was becoming more open to trying new things. With a quick nod he pulled his fingers out of her pussy, feeling her unhand his cock right before she grabbed his shoulder and gently pushed him back, climbing onto his lap. Obediently he laid back against the fluffy carpet, excitement reverberating through his body as Isuzu turned around and then crawled backwards, soon straddling his face.

Her side-tie panties were damp in the crotch area, enticing him to hook several fingers into them and tug them aside, revealing her pussy to him. The Commander waited only long enough for Isuzu to lean down before he grabbed her perky ass and pulled her down, his tongue taking a long, lustful lick of her pussy, tasting her sweet honey. The sudden lick elicited a cute squeak from Isuzu, the cruiser tilting her head down and looking back at him, embarrassed.

''Muu...'' Isuzu whined, her breath hot against his cock as she got into position – both of them in the 69 position.

A fact he was reminded of as lips touched the tip of his dick, and then wet warmth enveloped his shaft. He let out a deep groan of lust and grabbed her thighs, squeezing them as he endured the brief burst of overwhelming pleasure that raced down his dick. His shaft throbbed within her mouth, enticing Isuzu to purse her lips tightly around his dick to stop it from escaping, said lips gently sinking deeper down until she had just over half of his cock in her mouth.

The Commander returned the favour wholeheartedly, lapping at her folds for a bit before pushing his tongue into her hot core. He swirled his tongue around in wide, lustful circles, feeling her inner walls smother his wet appendage in an attempt to grip it but failing. His fingers dug into her thighs at the same time, massaging and groping them idly as his tongue explored her slick sex, his movements making Isuzu moan around his cock.

''M-Myaah...'' The cruiser pursed her lips tight and sucked, suppressing another moan. ''Mmph... slrp...''

Lips moved further south, and the Commander shuddered as Isuzu managed to deep-throat him, her wet lips pressed against the very base of his cock. His dick throbbed inside her hot mouth before she lifted her head back up, her saliva-coated tongue pressing against the top of his cock as she bobbed her head. The pleasure alone was enough to make his pelvis tighten with lust, his hips rocking upwards and gently thrusting into Isuzu's mouth.

''Mnph...'' His girlfriend moaned at that, drool trickling down his cock as she blew him.

Stifling another groan he went back to pleasuring her, pulling his tongue out of her hot core and replacing it with his fingers, jamming three of them in at once. Her slick insides gripped his digits and Isuzu moaned around his cock, her erotic voice tickling his dick with the vibrations. Yet even as he pumped his increasingly-sticky fingers into her dripping pussy Isuzu didn't stop pleasuring him, almost determined as she bobbed her head up-and-down his dick.

Wet sucks became hot slurps, her head tilting left-and-right as she tried to suck him off in the best way possible. He knew she was trying to make him cum first and the mere thought aroused him beyond words, his dick pulsating inside her mouth and swelling up as his orgasm neared, a burning want climbing up his shaft. It became increasingly hard to think and so he yanked his fingers back out of her slick slit, shoving his hungry tongue back into her and eating Isuzu out with renewed lust, his tongue swirling around her inner walls easily.

''Mmph... Cohmandah...!'' Isuzu's muffled mewl made his balls tighten, pleasure racing up his cock – when Isuzu suddenly gripped at his thighs, crying out around his cock.

Honey gushed around his exploring tongue, immediately encouraging him to lap up her tangy-sweet honey, ravenously eating his girlfriend out even as she orgasmed. Isuzu managed to keep moving her head, sucking between gasps – until finally she just grabbed his cock with her trembling hand and rapidly jerked him off, her lips pursed around the tip of his cock and sucking him off intensely.

The suction pushed him over the edge, and with a grunt of his own the Commander came, unloading thick splatters of cum into his girlfriend's mouth. Isuzu whimpered around it, her hand sliding along his saliva-coated cock and coaxing his cum out. Only a scarce few droplets of cum leaked out of her mouth and trickled down his length, the rest of it swiftly swallowed up until no more cum was left in her warm mouth.

''Mmph- haah~!'' Isuzu gasped as she leaned back, his cock springing out of her mouth and her hand wiping her lips clean. ''Hah... haah...''

Shakily Isuzu climbed off his dick, her legs trembling lightly from the post-orgasm weakness – twitches travelling through her body. Through breathless eyes the Commander watched as she crawled down the length of his body, soon ending at his waist and straddling him with her back facing him, her hand brushing against his sensitive cock. He groaned, earning a peek from Isuzu over her shoulder, but she just gently played with his dick – tickling it with her fingers, slowly stroking it, rubbing the tip with her thumb; she didn't outright pleasure him but just focused on keeping him hard.

After nearly a minute of gentle foreplay, Isuzu couldn't contain her want any longer. Shivering cutely the slim girl lifted herself up on her knees and guided his cock between her legs, the tip sliding along her wet slit – before Isuzu lowered her hips and impaled herself upon his cock.

''Mm!'' Isuzu immediately tensed up, back straight and shoulders stiff. ''A... Ah...''

The Commander groaned beneath her, sitting up on his elbows and breathlessly watching as Isuzu inched herself deeper down his dick. Her hot, velvety insides smothered and clenched around his cock, seizing up tight only to relax slightly as she exhaled, the process repeating itself in the next breath. Her oversized cream sweater didn't cover her rear, giving him an unimpeded view of his shaft disappearing between her wet folds, the firelight making them glisten alluringly.

Grunting softly the Commander sat up, wrapping his arms around Isuzu and earning a soft whimper from his lover. He kissed at her neck, lips grazing down her flesh until he reached her shoulder, smooching it affectionately. The cruiser blushed darkly at the attention, biting her bottom lip as she continued moving, moaning his name as she took his dick into her womanhood as gently as she could. Inch after inch was enveloped by her wet heat until his full length was snugly buried within her, the sensation of bottoming out in his girlfriend making the Commander groan.

''Mn...'' Isuzu shut her eyes as she moved a little more confidently. ''Ah, Mm... Commander...''

He replied by kissing her shoulder more, nipping gently at her flesh and earning himself a cute, almost scandalised gasp – embarrassment flushing across Isuzu's crimson cheeks. Yet the sight only encouraged him to do it more, leaving a trail of little love-bites along her creamy flesh and listening to her moan and whimper, intermittent gasps punctuating her erotic sounds. His hands weren't idle either, slowly creeping south and climbing up her stomach, feeling her up as he went until he reached her breasts.

Anything Isuzu wanted to moan out was swiftly silenced as the Commander leaned over her shoulder, claiming her kissable lips. Said lips parted in a quivering moan, pushing back against his as they made out mid-fuck, his cock twitching within her clenching heat when she began to move more earnestly, her shyness fading away as pleasure fogged up her mind. Her butt hit his pelvis with a quiet but ever-so-lewd smack, the repeated impacts enticing him to rock his hips to meet her bounces, stirring his dick around her slick insides.

''A-Ahh~'' Isuzu broke off the kiss with a trembling whimper. ''It feels too good...''

The Commander smiled, kissing her ear – whispering into it, asking her to lean forwards. Isuzu obeyed with a low moan, stopping her bouncing and instead leaning forth slowly, allowing him to follow her movement; keeping his cock snugly buried inside her even as they changed positions. In moments Isuzu was down on her hands and knees, lithe fingers curling into the carpet and his pelvis pressing against her ass, a shiver lancing through her body when he throbbed within her innermost parts.

Firelight wavered across her body, dancing across her creamy flesh as he untied her panties and let them fall to the floor, leaving nothing to get in the way. Isuzu's face burned but she didn't comment, only biting her bottom lip and getting ready for what was to come – and she wasn't disappointed, gasping in surprised pleasure as he suddenly jerked his hips forth, stuffing her in one clean thrust and letting her feel him throb against her deepest parts.

''M-Mm!'' Isuzu arched her back as he pulled halfway out with equal swiftness, the tip of his dick hitting her deepest parts a second later.

Not even trying to stifle his deep groan the Commander grabbed Isuzu's slim hips and pounded her with passionate intensity, relishing the resounding smack of his pelvis hitting her ass, watching her butt jiggle lightly from the impact. Her whole body jerked forwards from the force of his thrusts, and as he found a good tempo he took the time to lustfully watch her body react; of how her shoulders curled inwards as she resisted the curling licks of warmth up her spine, as her stomach buckled as she endured the cock hitting her deepest parts, as her thighs trembled under her own weight.

The arousing sight was only made more so when Isuzu peeked at him from over her shoulder, bits of her fringe clinging to her sweaty forehead. Acting in an instant the Commander leaned down, spooning Isuzu and ceasing his thrusts for a good second – before he claimed her lips in a deep, hungry kiss, utterly devouring her embarrassed moan as she succumbed to his lust and kissed back, squeezing his dick with her slick inner walls.

Then the kiss broke off, and he went straight back to pounding her. ''Mn!''

''Ah~!'' Isuzu bowed her head forth, whimpering as his tempo sped up. ''Ah, Command- Mm, I... a-ahh~''

The Commander smiled tightly, breathing out quick, heavy breaths as he focused on just plunging himself balls-deep inside the cruiser, her slick inner walls squeezing his dick pleasurably. One of the straps of her camisole had slipped off but he didn't pay it any mind, too busy sliding into her to focus on anything else – other than the creeping warmth that climbed up his cock. His orgasm was rapidly approaching, his prior climax leaving all his nerves aflame and making the movements all the more intense.

''Hah, Mn...!'' The sound of smacking skin rung in his ears, the pressure in his cock mounting – and soon the Commander couldn't take it, pleasure rushing up his length. ''Gh-!''

Isuzu cried out in surprise as he slammed into her, ropes of cum splattering deep into her quivering pussy. She tightened up like a vice, her own orgasm hitting like a freight train and sending her body into buckling spasms, her shoulders trembling as she endured it. His hips worked on automatic, jerking back-and-forth and spurting more of his cum load into her with each ragged thrust, giving her a creampie.

Gradually his thrusts slowed, his stamina waning until he couldn't do anything more than hump Isuzu from behind, spooning her. He groaned breathlessly into her ear and she quivered beneath him, whimpering cutely when he pulled out – allowing her arms to finally give out and send her flopping down onto the carpet.

For a good few seconds she just laid flat on her face, panting heavily, before finally rolling over onto her back.

''Mhn...'' Isuzu cutely grunted as she rolled, panting heavily. ''C-Commander...''

The Commander twitched, soaking in the sight of Isuzu. Her face flushed a deep red, her inviting pink lips parted as she panted, one strap of her camisole slipped off her slim shoulder to reveal the side of her left breast, her legs spread and trembling, her pussy leaking cum and arousal and staining her inner-thighs – she posed a decidedly inviting, arousing figure. And one he couldn't resist.

''Ah- Mm~'' Isuzu's cute whimper melted into a moan as he claimed her lips, grabbing her hips in a strong grip.

He tugged her towards him, and knowing what he wanted she shifted closer – her legs winding around his waist and her arms going behind herself, both of them sitting lotus-style. Not wasting a second the Commander grabbed his dick and rubbed it against her slick lower lips, groaning into her mouth from the gentle friction and making his girlfriend mewl back, her legs shifting a little and allowing him to get into a better position.

And soon, he ceased his teasing and rolled his hips forth, easing himself into her. A muffled sound of bliss escaped Isuzu and she wrapped her legs around his waist more tightly, pulling his crotch flush against hers and making him instantly bottom out inside her, both of them moaning in bliss. He took a good second to enjoy the feeling, pulling back from the kiss and staring down at their connected parts, his gaze soon sliding up to Isuzu's face as she laid her hands on his shoulders for support.

His gaze dropped to her chest, and then in a heartbeat the Commander reached out and peeled the straps of her camisole down. Isuzu squeaked faintly but when he tugged on her arms she demurely lowered them long enough for him to pull her top down, causing her loose camisole to pool around her waist; exposing her plump, medium-sized breasts, her pink nipples perky and as alluring as ever.

''Mn...'' The Commander stifled a grunt as he began to rock his hips, thrusting up into her clenching heat.

Demurely Isuzu moaned, pursing her lips and moving with him, impaling herself upon his erect cock. The new position made her squeeze him tighter, the cum splattered inside her womanhood making her feel sticky and sloppy, the sensation only proving to turn him on more – and encouraging him to buck his hips more forcefully, confident she could handle it.

In response Isuzu tipped her head back, moaning lewdly and tightening around his dick, the slick hotness of her pussy growing more intense – briefly making him slow down before he immediately sped up again, grunting huskily as he smacked his pelvis against her. His left hand shifted to her lower back to support her as he moved his hips more vigorously, the squelching sound of his cock entering her velvety tunnel ringing in his ears.

''Ah, ah...'' Isuzu moaned softly, tightening up when he grabbed her right breast and groped it. ''A-Ah, no...''

A kiss silenced the cruiser, her embarrassed moan muffled as he stopped thrusting. Instead he grabbed ahold of her sides and eased her back onto the carpet, swiftly grabbing her wrists next and pinning them down – before with barely a moment of delay he resumed thrusting, releasing a deep groan as he pounded Isuzu with skin-slapping intensity, his cock plunging into her slick hole vigorously.

The wet friction felt heavenly, and Isuzu felt every bit of it – crying out in sweet bliss as he filled her with his cock. Their pelvises met with resounding smacks of skin, her boobs jiggling about from the force of his thrusts. Even when he laid his right hand on her breast and groped it her tit still jiggled and bounced into his hand, his thumb finding her pink nipple and flicking it about in a fit of passion, relishing her inevitable moan of bliss.

''Mm, Commander... I-I can't...'' Isuzu breathed out, her legs locking behind his back tightly for emphasis.

Out of breath he nodded, giving her breast one last squeeze before putting his hand on the carpet next to her. Pleasure climbed up his cock as his thrusts got faster, abandoning any sense of rhythm in favour of just jamming his cock into Isuzu's glistening sex, the wet sounds of him entering her adding to the erotic atmosphere. Beneath him Isuzu gripped onto the carpet, back arching and mouth hanging open in bliss, her slick inner walls wringing his cock desperately.

''Ah, haah...!'' Isuzu screwed her eyes shut, lips pursing tight – before she suddenly buckled, and came undone. ''Hyaa~!''

Wet flesh smothered his cock, and in an instant the Commander came – groaning deeply as he buried his cock into her. A pulse of pleasure raced up his length and he immediately came inside her, jerking his hips back-and-forth raggedly as he unloaded ropes of cum into her hot depths, each spurt of cum adding the icing to Isuzu's powerful orgasm.

His prior orgasms caught up with him, sucking the stamina out of him after just a few hard thrusts – and with a gasp he collapsed atop Isuzu, burying his face into her neck. Isuzu gasped and moaned in reply, clutching onto his back and panting out heavy breaths into his ear, the warm air tickling his earlobe.

''Ah... haah...'' Isuzu wriggled beneath him. ''Commander...''

He lifted himself up slightly, looking her in the eye – a breathless, loving smile curling at her lips.

''I-I love you...''

His lips met hers in a deep kiss; breathing the words out as their lips drifted apart. ''Love you too, Isuzu-chan.''

The gentle breath made her quiver, face red and a flustered, happy smile trembling across her lips.

And then with a beautiful giggle Isuzu rolled them over, lips on his; their forms silhouetted by the fireplace behind them.
