Straightforward Love

''I was thinking we should grab more grub next time, I'm sick of eatin' beans all the time...''

''But they're good for you.''

''Good for my ass more like...''

The grumblings drew a round of chuckles and giggles from the various members of the Astral Express currently assembled in one of the frontmost compartments, all sat down on boxes or off-centre tables as they ate dinner – having it when in the process of rearranging things.

It was another normal evening on the Astral Express for them all. For the most part the gang had just sat around and relaxed for a change, just taking in the sight of the distant stars as the mystical train took them across the universe. Nobody thought about what their plan was though, or where they were going to next; all of it pushed out of mind as they just decompressed for a few hours.

March 7th hummed merrily as sat on one of the boxes, her own dinner long since polished off along with her ice cream dessert, the taste of strawberry still rich on her tongue. The memory of it just made her smile a tiny bit wider, kicking her legs lightly as she hummed and already eagerly waiting for tomorrow's dinner so she could try the cherry-chocolate one they'd bought during their stop.

Her train of thought, however, was interrupted as a pair of arms wrapped around her, preluding the chin that came to rest upon her shoulder. ''March.''

''Hm? What is it Caelus?'' The pink-haired girl chirped, curious.

''...I want you.'' Caelus said in his usual low, mumbling tone, staring her straight in the eyes as he spoke. ''Now.''

''E-Eh? Aha... I suppose that's fine...'' March 7th blushed but smiled all the same, petting his hand. ''Let's go to your room?''

Caelus simply bobbed his head, and March could only blush as the handsome boy picked her up in a bridal carry – and before she could say anything to the others, some of whom were now looking, Caelus simply turned and carried her away.

''U-Um, bye guys! W-We're going to bed early!''

A few murmured acknowledgements her way but were either too busy eating to care, or knew full well that wasn't the case.

X-x-X

''Mm... hehe~''

March's gentle giggle tickled Caelus's lips, bringing a faint smile to the young man's features before he kissed her once more, earning a muted coo in exchange. His hands ran up her waist slowly, pushing her clothes flush against her skin and holding her close, her own hands wrapped over his shoulders and down his back, keeping them as close as possible.

They were back in his room, the door locked and with her sat upon his lap. The position wasn't an unfamiliar one after all the time they'd spent together nor was their activities new either – a fact Caelus made apparent as he dropped his hands to her ass. March moaned softly and drew back from the kiss, her cheeks painted a seemingly-permanent red as she felt him grope her butt, her skirt hiked up in the process.

Then he leaned in, but rather than go for her lips he went for her neck – suddenly attacking it with a slow suck. March cried out softly, lolling her head in the opposite direction and providing him with an easier target, his lips grazing over her flesh ravenously and peppering it with kisses both gentle and rough, marking her in several places with hickeys.

''Mn, no biting...'' March breathed out, tugging on his hair. ''The others will see.''

''I know.'' Caelus hummed, nipping her neck again – tightening his hold on her. ''That way they'll know you're mine.''

The gentle possessiveness made March blush harder, a sheepish laugh escaping her as she nudged him back – kissing him on the lips instead. The Trailblazer was all too happy to kiss her back, humming into it; his stoic expression contrasting sharply with the vigour with which he moved, his fingers sinking into her ass as he felt her up, pulling her body towards his own. March on the other hand let her right hand slip down his front, tracing his shirt down to his belt and tugging on it, her other hand soon joining it and working his belt loose; allowing her lithe hands to unbuckle it and loosen his pants. Moments later his cock was tugged out into the open, soft but quickly getting erect.

''We've not done anything but kissing and it's already so big?'' March mumbled, a flustered little smile curling at her lips.

At that, Caelus just shrugged. ''That's all it takes when it's with you.''

The words, spoken so half-heartedly and with a stoic expression, still managed to make March's heart skip a beat – a sheepish giggle escaping her as she shuffled back, sliding off of his lap. Caelus didn't stop her and she knelt down upon the carpet between his legs, her adoring gaze peering up into his own, her head moving in – and a soft, stilted grunt escaped Caelus as her tongue flicked the tip of his dick, lifting it up before gravity made it fall back down.

It merely preluded the many more licks that followed, her tongue lifting his cock up as she stroked the underside of it – humming under her breath as she tilted her head, letting her tongue slide along the sides of his shaft too before running over the very tip. Though Caelus's expression didn't change the tightness in his brow hinted at his pleasure, as did the pent-up breath he let out a second later. If anything his aloof nature just made it a weird challenge for her, eager to see what faces he would make when overflowing with goodness.

''Mm... Caelus...'' March breathed out, dragging her tongue along his tip more.

Caelus responded by putting his hand on the top of her head, nudging her closer. With a shy smile March took the hint and kissed the tip – before letting her lips part around it and took him into her mouth. The gentle groan that escaped him made her heart flutter and her eyes closed, keeping her teeth out of the way as she took more and more of his dick into her mouth until she felt the tip near the back of her throat, the sensation prompting her to suck her way back up to the tip.

And then plunge back down again, eliciting another low groan from her partner as she gave him head – bobbing her head back-and-forth with a slew of hums interspersed between breaths. She could feel his dick sliding over her tongue as she moved, felt him throb against her lips as they pursed against his shaft; the assortment of sensations only turning her on more and more, getting her in the mood.

Doubly so when Caelus threaded his fingers through her hair, holding the back of her head and pushing her down insistently. Obediently March complied, grunting as the tip nuzzled the back of her throat once, twice – and on the third go she dared to take it down her throat. She very nearly gagged but held back the reflex, enduring the slight discomfort and enjoying the groan it coaxed out of her partner.

That, if anything, just gave her reason to deep-throat him more.

Caelus for his part pursed his lips, hissing out a soft breath as he kept pulling her down into his crotch, her wet mouth accommodating his cock nicely and her lips soft as they pressed against his girth. The slightest sensation felt electric and it was a task and a half to even breathe normally; grunts spilling out past his lips as she kept sucking him off. When he peered down at her too, if she pulled back far enough, he could get a glimpse down her dress at her nice boobs too.

Such thoughts were purged from his mind as another heavenly suck coaxed waves of pleasure up his shaft, his muscles drawn taut and a groan escaping him once more. Tensing his back he reached down with both hands now, holding March's head and pulling her down into his crotch – feeling her nose squish against his groin while his cock was firmly sheathed between her lips. Though March grunted a little with earnest determination she kept slurping his cock, her left hand on his thigh whilst her right cupped his balls and squeezed them, uncaring of the fact her spit drooled down his shaft and into her waiting palm.

''Nn... March...'' Caelus grunted out, panting heavily.

March said nothing, instead she opened her eyes and stared right up at him, determination within them as she kept slurping his cock – and 'slurping' was truly the best word for it. With spit dribbling down his cock in liberal quantities the pink-haired girl bobbed her head and sucked him off eagerly, utterly worshipping his cock with every suck and lick, her head tilting ever-so-slightly as she worked to make sure not a hint of dick went unloved.

The barrage of affection rapidly wore on Caelus's stamina, his expression growing tight and breathing sharp – the telltale throb of his cock giving away how close he really was. March just kept at it, pushing past her own discomfort as she gave her lover head, a slew of hot wet grunts flooding the bedroom-

''N-Nn!''

-until with a harsh grunt, Caelus came. He pushed her down just as he peaked and March swallowed the torrent of seed he blasted down her throat – quick gulps becoming lengthier and slower as she made sure to not let a single drop escape.

Gradually the hold on her head loosened and March slowly raised her head, letting his dick slip out – until at last the tip fell from her lips and the pink-haired girl breathed out a sigh. A small smile curled at her lips as she wiped her mouth and chin dry, none of his seed having escaping her mouth and all of it ending in her tummy, the warmth that now resided within it making her hot in a different sense of the word.

''Mn, Caelus...'' March breathed – nay, whined his name out, rising to her feet. ''Can we do it now?''

''Sure.'' The casual way he said it returned some warmth to her cheeks.

Yet with a seemingly-boundless enthusiasm the pink-haired girl hopped to her feet, reaching up her skirt and fiddling about for a second – before with a soft thump, her panties ended around her ankles, pale pink in colour just like her hair. March's cheeks burned a darker shade of red but without hesitation she clambered onto Caelus's lap, her hands settling on his shoulders as his own gripped her hips – and a soft squeak soon escaped March as she felt his hot, erect cock press against her folds, tempting her to rock her hips gently and rub herself on his tip.

The little friction was enough to leave her panting, her eyes becoming half-lidded with want. A soft whine soon passed her lips as she raised herself up a little bit more, his tip dipping in the tiniest bit – when at last March eased herself down, moaning as she felt his cock sink into her. Caelus's grip grew tight and a low grunt escaped him, eyes screwing shut and with pleasure written across his face as he felt her hot insides coil around his dick, her pussy so warm and wet that it just felt heavenly.

''Ahn...'' March moaned under her breath as she came to a stop; most of his cock in her. ''It's still twitching a lot... does it feel that good?''

Caelus didn't deign to reply with words, but instead did so with actions. Namely by kissing her. March squeaked at first but soon melted into it, a hot groan tumbling from her lips as she kissed him back, her hands leaving his shoulders and her arms winding down his back instead, pressing her modest bust against his chest. In response Caelus slid his hands down to her peachy ass and gave it a firm grope, helping heft her up before gravity dropped March back down onto his dick, a moan jolting from her lips at the sensation.

Digging her knees into the bed March started to bounce in earnest; rising up until only the tip was in before impaling herself back down, getting most of his cock inside her with every movement. Her hips roll, her back arched, and once more her lips were claimed in a heated kiss – not that it did much to muffle her horny moans, her cheeks flushed red with embarrassment yet her eyes darkened by lust. A lust silently matched by Caelus himself, his lips connecting with hers again and again, never able to get enough of the simple act.

The sound of their flesh smacking together began to echo throughout his bedroom but neither cared, neither stopped. If anything March picked up the pace and lolled her head back, moaning happily as she felt his sizeable cock spear into her depths, scraping her walls before her insides clamped around it – the snug grip coaxing a groan out of Caelus, his fingers sinking into her ass roughly, helping her move.

''Mn, ah, h-haah~'' March mewled out, tilting her head back down and resting it against his own. ''Caelus, you're twitching a lot inside of me... it feels so good...''

In response the stoic Trailblazer shifted his hand up – and March squeaked as he suddenly yanked her top open, revealing her bra-clad chest. The bra didn't last more than a few seconds before it too was practically ripped off, freeing her medium-sized chest and allowing his hands to grab them greedily – his mere touch reducing March to a moaning mess, her head light as she felt him grope and fondle her so roughly, so earnestly, that the excitement coursing through her was enough to make her dizzy.

Or maybe it was because it was a little hard to breathe with him grabbing her tits so much, but she didn't voice that. She liked it when he got a bit rough anyway.

The thought was purged from March's mind as Caelus bucked his hips, thrusting his swollen cock up between her petals and fucking a high-pitched moan from her lips. With eyes screwed shut and back arched March frantically impaled herself down onto his dick, her insides tying themselves into knots as she felt her orgasm rapidly near, every bounce threatening to be her last and her breath catching in her throat, his own grunts suddenly becoming tight.

And then, almost in unison, they came. Ropes of molten warmth shot up into her and March let out the squeal she'd been holding back, her orgasmic cry piercing through the still air and her head thrown back – incidentally exposing her neck and allowing Caelus to bury his face it in, kissing it aggressively as he held her, busting his load inside of her. The pink-haired girl quaked in his grip, rolling her hips frantically and whimpering when he sucked on her neck, her motions slowing-

-until at last her stamina ran out and March slumped against him, mewling.

For a long minute the only sound in Caelus's room was their shared panting; the occasional moan or grunt interspersing their words before March finally found the strength to sit up – moaning under her breath as she felt his cock slide out of her thoroughly-fucked pussy. Her thighs still quaked from the aftershocks and it took all the strength she had to crawl over onto the bed proper and lay down; face in the sheets and just breathing.

'...the quilt smells of Caelus...' March thought to herself with pinkened cheeks.

A beat, and then she felt hands on her hips. March had only a second to feel confusion before she was spun around onto her back, her pink cheeks blossoming into deep scarlet ones as she came face-to-face with a horny Caelus, his own cheeks warm but his eyes half-lidded in unspoken want. With a demure smile March bobbed her head, her legs slowly opening and allowing Caelus between them, his erect cock pressing against her sex before he grabbed his cock and guided himself to her wet opening.

Then he was inside of her, pushing a low moan out of March as her tender insides were filled once more. Caelus himself groaned with her, hands on either side of her and incidentally landing over her own – prompting him to simply curl in his fingers in, holding her hands. That, if anything, just flustered March even more, but before she could utter a single syllable Caelus darted down and mashed his mouth against her own, muffling her moan as he started to thrust into her.

''M-Mm, mn, mmph~'' March moaned happily into the extended kiss, her nails gently digging into his knuckles as she held his hands tight – her legs soon wrapping around his hips too.

That just made Caelus pick up the pace; his slow thrusts swiftly escalating into something far more passionate, their flesh audibly slapping together as he went to town on his partner. March cried out at that, her voice ringing out until his lips connected with hers once more, the deep kiss stealing her breath and rendering her a moaning mess underneath him – her hands slipping out of his just so she could grab onto his back, bunching his shirt up and pulling his body down against her own.

Caelus replied by way of holding her shoulders; grunting right into her ear as he pounded her – his thrusts short and rough, jamming his dick into her snug wet hole, the slickness of it making a slew of wet sounds that just turned them on even more. As did the muffled squeaks of the bed and the dull thuds of the headboard, the array of noises just reinforcing the situation to them and making it so much more lewd.

''Mn~! Y-Yes...!'' March cried out happily – her lips soon reclaimed once more. ''Mmph~!''

His cock plunged deep inside of her with every thrust, kissing her innermost parts almost and fucking March to new heights of pleasure – her mind putty as he pounded it into such. With him holding her shoulders he practically squished her into him, their bodies close and their loins even closer; the slick sounds escaping their joined parts only pushing them closer to their ends. The slick friction, the tight grips; the lewd noises utterly permeated their room.

They also became a constant, time bleeding away as they pair went at it. Kisses interrupted moans and wandering hands soon copped a feel of March's tits, squeezing a mewl out of the pink-haired girl before Caelus kissed her once more, his cock throbbing between her petals as he did so. If anything that just made March hold onto him tighter, whimpering for the load she knew was coming – hanging on the edge as she resisted her imminent climax, wanting to cum with him.

A desire soon granted as the pair kept at it, kept moving – and then at last Caelus couldn't take it.

March gasped as hot jets of warmth splattered inside of her, painting her inner walls – and then she went over the edge, her gasp building into a cry of euphoria as her orgasm swept through her. She writhed in bliss but he held onto her throughout it, his pumps short but strong as he poured all of his warmth into her depths, adding the icing to her orgasm and threatening to make her pass out from the stimulation.

She came down from her high just before that point; gasping and flopping back against the bed. Her chest heaved with every deep breath she drew and she shivered as she felt him pull out, the sudden absence of his cock leaving her feeling empty... outside of the warmth he left inside of her, of course.

''Mm... Cae...'' March breathed, giggling sillily at the nickname. ''I really love doing this, with you...''

March turned her head, smiling at her partner... only to realise he'd conked out almost immediately after nutting, snoozing into the pillow.

…

''You dummy... hehe~''
