"Sit still, big guy. You promised."

 

"That was before you tied me up." And also nearly a year ago, when they met up in Fontaine. He didn't think she would remember! Childe winced as she tightened his scarf around his wrist, his arm bent at an awkward angle. He couldn't focus on the dull ache radiating through his muscles, though, too focused on the strain in his pants and the intoxicating scent of wildflowers and the wind of the woman on top of him. "Ngh–"

 

"Aren't promises sacred or something?" Lumine cooed, brushing her silky blonde hair out of her face. Any other time, he might agree with her, but right now he was having a very, very hard time maintaining it. "Can you really not handle a little light teasing?"

 

"Ha..." He grit his teeth, the sound of fabric stretching barely audible above their desperate and shaky breaths. "This isn't a game."

 

"Is it not?" She cooed. "And yet, I'm having so much fun."

 

She accentuated every last word, her full lips red from their earlier frenzied kisses. His head spun with each mischievous bat of her long eyelashes, a silent challenge going unspoken between them. He could do it right now, could snap free of the restraints and apologize later, pin her beneath him and take her until both of them were crying out so loudly that the rest of the damn train heard them. 

 

The lust coursing through his veins skyrocketed as she lifted her new skirt, letting him see what he desired. Fuck. She'd long removed her cotton undergarments, thin lines of her slick dripping down her milky white thighs. Lumine licked her lips, arching her hips closer until he swore he could feel the heat of her cunt right against his cock.

 

A dreadfully pathetic moan tore out of his chest.

 

"Please," He stammered, his heart beating so fast he swore it might burst out of his chest.

 

"Oh?" She cooed, leaning forward to grind her puffy pink pussy lips along his cock and coat him with her own arousal. Another low groan reverberated through his body, his nails digging into the meat of her thigh for some sense of stability. It only made her giggle louder and grind a little faster. "Begging for it already?"

 

"Comrade–" This was fucking ridiculous. Everything between them was more of a battle anyways, and surely she would appreciate him making this a challenge! 

 

No sooner had he had the thought that she pressed closer against him, her shaky breath hot against his cheeks. Her hand pinned his above his head, her thumb pressing deep into his pulse as she rolled those wide hips in a circle, her wet lips grinding against his aching cock with a speed that rivaled his own thrusts. 

 

"Lumine," He snarled, his free hand gripping her thigh like a lifeline, "Just put it in–"

 

"Ah, ah," She said, panting, pretty features hazy with desire. Gods, he would love to lick the beads of sweat rolling down her cheek, savoring the taste of her. "I'm in control here, and I'm enjoying myself."

 

His wrist strained against the scarf and her grip, but no matter what he tried he could not work up the strength to tear free. Perhaps that was because he knew she would stop all of this in a split second, would step away and go find someone else to fulfill her desires. Perhaps it came from the fact that he liked her in control– okay, yes, that was definitely part of it, seeing as their rendezvous before had been much the same. And maybe even a little bit of it came from the fact that if he moved forward, he would ruin the suspense building up between them, that long-held desire they hadn't been able to have since Fontaine, burning deep inside him like a little flame, growing and growing in size with each thought of her. 

 

Part of him also could not make his body work, shell-shocked by the situation he found himself in. Lumine did not have that problem. She grinded down against him without ever letting him inside, panting and whimpering and whining until all he could hear were her moans and the delicious wet noises against them. Her slippery cunt rolled against his cock, up and down, faster and faster, using him to her own satisfaction. All it would take was adjusting the angle to slide in, to give them the orgasm they both craved after so long apart, and yet for some gods-forsaken reason she would not allow him this pleasure–

 

Before he could even say another word or plead for another chance to satisfy both of their obvious desires, her breath caught in her throat, a choked cry lodged in her mouth. He knew that far too well, knew the trembling of her body so intimately that he could clearly imagine it on nights when the distance became too much. Her orgasm spilled over her like a flood, doing nothing to hide her high-pitched moan despite the eager listeners elsewhere on this train. Childe cursed as her pretty thighs closed around him, her aching cunt still grinding on his cock as her pleasure drowned her. 

 

As she came down from her peak, her chest heaving with the remnants of her orgasm still spreading to every inch of her body, Childe grinned. "My turn," He snarled, ripping free of the last restraints holding him back.

 

Lumine's eyes widened as he pinned her flat on her back, the bump and rattle of the train much more noticeable. "Wait–" She stammered, head still swirling from the remnants of her own orgasm, "Childe–"

 

"Ah, ah," He growled, scrambling to undo the pitiful restraint his scarf made so he could tie it around her wrists. "You used me. Now I get to use you."

 

"But–"

 

"What's the matter?" He cooed in that stupid, sickeningly sweet tone. "Can't handle a little teasing?"

 

Any other time, she might have laughed at his obvious challenge, or sassed him back with her own cheeky retort. Instead, her brain was mush, the fog of her lust outweighing any of the smarts she might have prided herself in. "You're a jerk," She finally managed, sucking in great, gasping breaths to try and soothe her racing heart.

 

A crooked smile stretched across the Harbinger's face, sliding his dark slacks down further and crawling over her body. The sheer size of him enveloped her in a single move, the heat from his chest and breath enough to cut through the chill seeping through the train cabin's windows. 

 

"A jerk who's about to have you screaming in pleasure," He purred, voice deep and husky as he nuzzled her ear. A pathetic whine bubbled out of her, her wrists straining against the scarf. Maybe she would have been able to break free if she could focus on anything but the feel of his thick cock pressing against her folds, still waiting for permission to continue, his body trembling with barely-concealed restraint. When she didn't respond, too awestruck, he hummed, "Let me have my way with you."

 

Okay, yeah. She was in for it. 

 

No sooner had she given the smallest of nods did he pounce her like a rabid animal, his mouth kissing and nipping at any inch of skin he could find. Had he really been holding back that much?! She expected a little affection, but not him covering her throat with love bites wherever he could reach, marking her as his for any wandering eyes that might look her way when she arrived at the capitol.

 

Another long, drawn out moan tore out of her chest as he bent her thighs apart with his large, gloved hands, keeping her spread wide open for him. He cursed in his mother tongue, his eyes darkening as he stared at her pinned beneath him like this, "Gods, you're so wet," He growled, grinding his cock against her swollen pussy lips. "Got yourself this riled up, didn't you?"

 

"Nnn..." She craned her neck to get a better look at the space between them, practically drooling as she started rolling her hips once more. Now she understood the torment of being made to wait; all she wanted was him inside her, deep, deep inside her, so full of him that the memory of it would stain her for hours after they separated on the train platform.

 

"Hey," He cooed, that familiar smirk on his cheeks again, "Eyes on me, girlie."

 

She barely managed to focus on his face before he thrust inside, the wave of pleasure from his thick cock splitting her in two nearly sending her over the edge a second time. Stars flooded her vision, her mouth wide open with a silent, star-struck moan. She strained against the scarf even though it would do no good, her body too enraptured in pleasure to manage the same tear of the thick fabric as he had done. She still hadn't recovered from the first satisfying thrust that had filled every inch of her when he rolled his hips again, deep with each long stroke.

 

His thrusts started slow at first, as if he were trying to remember the rhythm that worked well between them. His gloved thumb rolled over her swollen, wet clit, her hips arching with each flick of his finger. Her aching cunt squeezed around him, her pathetic moans in perfect sync. Then, when he was sure he had the pace right, he thrust his fat cock deeper inside her, groaning Snezhnayan curses under his breath as he fucked her silly.

 

"Open your mouth," He suddenly ordered, pressing his palm flat against her thick thigh to keep her legs spread.

 

The last remaining sliver of her defiance reared its ugly head again. She couldn't let him get away with this. She had to maintain some of her reputation as a brat. So she kept her mouth closed, her lips pressed in a thin line despite the pleasure coursing through her core.

 

"Lumine," He growled, animalistic.

 

She smiled, unable to help herself. "Make me."

 

A pause. Then, like everything he did, Childe snarled, moving with a surge of speed faster than the raising tide. To her surprise, he forcefully grabbed her chin with his wide palm and squeezed tight. Tighter, tighter, until her jaws ached and were forcibly pried open. She half-expected him to lean in and kiss her, to run his tongue along hers until the both of them could barely breath from trying to swallow the other whole. He didn't lean any closer, though, nor did he let her close the gap between them. Instead, he licked his thin lips and let his tongue stick out, a thick line of spit trailing from his mouth down, down, down onto hers. 

 

Oh sweet Archons, save her. What the fuck had he gotten into while they were apart? What would it take to get him to do it again?

 

Lumine's heart skipped a beat as his saliva landed on her own tongue, the taste of him almost more intoxicating than the slow, steady thrusts he fucked into her. She must have looked as fuck-drunk as she felt, as he actually laughed out loud as though he had won the battle between them. She rolled her hips in time with his, eager to feel the waves of her climax race through her again. Faster and faster, more and more and more, her greed only growing with the desire for more. If she could just angle her hips right– if she could just wiggle free of the restraints a little more–

 

Childe pressed her flat against the bench, a silent reminder he was in control. Lumine almost let out a petulant whine, only cutting herself off as he yanked her thick thighs closer to him and bent her back in a pose stretching her flexibility. He pushed her knees towards her chest, the tight pose allowing for him to thrust even deeper into her tight, wet hole all the way to the base. This time, she didn't try to silence herself– though, admittedly, she wasn't sure she'd tried at all the rest of the evening– her body trembling with waves of pleasure with each deep thrust. 

 

"You gotta be quiet, myla," He hissed, pinning her to the seat with all of his weight, the heat of him swallowing her whole. "They'll hear."

 

She really didn't care. "Let them."

 

"Not this time," He growled– was that his jealousy peaking through? Gods, he was such a moron; here she was literally fucking him back to try and bring them both to their peaks and he was worrying about someone else seeing her and wanting a piece.

 

Those same wicked thoughts filled her head, and before she could ponder the danger she might put them in, Lumine let out a slow, drawn out moan.

 

In a flash, Childe covered her mouth and nose completely with his gloved hand, cutting off any air. She flinched, struggling against him as she struggled to catch her breath, chest tight with "Behave," He ordered, his voice barely above a whisper as he leaned in close to her, "And I'll replace my hand with my mouth and you can breathe me in instead."

 

What a cocky asshole! And yet, her head spun from a lack of air and the pleasure coursing through her veins, her eyes fluttering with each thud of her heart against her chest. With each passing moment she wondered if she might slip into unconsciousness, trying to find a way out of this situation.

 

As her eyes fluttered from the lack of air, that wicked grin stretched across his handsome, freckled features. "Are you going to be a good girl?"

 

Yes, yes. His good girl. His.

 

Despite not managing to find the right words, she must have been believable enough, as he leaned in to kiss her like he wanted to swallow her whole. Just as he had predicted, she sucked in a great gasp of him, filling her lungs with a desperate breath of air. Her head swam as the oxygen reached her brain, her body erupting in a plethora of gooseflesh on any inch of exposed skin. She moaned again, but his mouth silenced it, the noise reverberating through his chest. Their tongues collided, trying to commit the taste of him to memory since it filled her with such pleasure that she could already feel the tendrils of her orgasm inching closer like little flames reaching for new kindling. Or was it the way he arched her body back further, her hips off of the bunk seat and entirely resting on his muscular thighs, the angle of his cock grazing against her most sensitive area with each deep, quickened thrust? 

 

Whatever the case, she could barely keep up, her little noises filling the space between them the same way the sloppy wet sounds of his cock pounding deep inside her soaked cunt filled the train car. She moved to wrap her bound arms around his neck, making it so he couldn't stop kissing her. Her boots pressed into the dimples at the base of his spine, refusing to let him pull out no matter how hard he might have tried. Childe audibly moaned into her mouth, the sound escaping the space between them to echo around the small train car– so much for him warning her to be quiet– as his hurried thrusts picked up the pace. 

 

It hit her first, a wave of white hot pleasure starting in her core and exploding like a firework throughout her entire body. Lumine cried out, not even bothering to try even if she wanted to be his good girl that followed his orders. Warmth flooded her insides, his thick seed filling her aching hole with each twitch of his cock. His fingers dug into her palm so hard she knew it would leave bruises, memories of their time together etched into her skin. 

 

Before long, the roar of pleasure between them settled into satisfied desire, the hurried lust easing into lazy affection. His chest heaved with great gasps of air, the sound and smell and feel of him only dragging out the exhilarating encounter even further. He refused to pull out, not that she would let him, too full of his seed to consider anything else. All the while, he left little kisses along her cheeks and neck, peppering the skin his teeth had nipped and suckled on in the midst of their fervor. His gloved thumb, the one that had been so forceful in making her open her jaw to comply with his demands, gently ran along her cheekbone, so soft she could barely register it.

 

She should have been completely and utterly satisfied. Should have gotten her fill of him so they could separate and go back to being on opposite sides of a looming conflict instead of two lovers engaging in the same mess they always found themselves in during these quiet moments alone. And yet...

 

"How much longer until we get to Snezhnograd?" She murmured, running her fingers through his copper curls.

 

"Mmm... another hour or so." He pressed another gentle kiss along her collarbone. "Why?"

 

A smile stretched across her features. "Want to kill some more time?"
