With a mischievous grin on his face, he couldn't help but taunt her playfully. "Ohoho,~ Ojou-chan, when it comes to pure strength…" he declared confidently, placing a hand on his waist while raising the other one in the air. As his eyes closed, a sly smile formed on his lips, hinting at a devious plan brewing within his mind.

"...I bet i’d win. Wanna try arm-wrestling me?"

Eagerly, he leaned forward, his fingertips brushing against the table as he waited for her to reciprocate. A mischievous glint gleamed in his eyes; it was clear that this wasn't merely a casual challenge for him. "Alright, Ojou-chan," Childe purred, pressing his hand flat on the surface of the table, fingers spread wide, muscles tensing beneath pale skin. His grin widened further as he waited impatiently for her to take up the challenge.

"C'mon, I know you won't back down," he taunted softly, arching an eyebrow in amusement at her predicament."C'mon, I know you won't back down," he taunted softly, arching an eyebrow in amusement at her predicament.

His other hand gripped the

His other hand gripped the edge of the table, fingers curling around it as he leaned closer to her, practically daring her with his gaze. His expression was intense, a mix of challenge and amusement dancing across his features. The wind blew through his mane of fiery hair, only serving to make him seem more vibrant and alive in that moment. As he prepared for the contest, Childe's muscles tensed and rippled beneath his clothes, drawing her gaze towards them despite herself.

There was no question about it; he was eager for this match. His eyes met hers once more, unblinking as they challenged her to accept or deny the offer. The silence stretched between them, thick with anticipation and the thrill of potential competition.

Childe couldn't help but notice Lumine's exposed nipple, the color deepening into an enticing shade of pink as she moved. It sent a jolt through his system, making him harder than he already was. He quickly forced his attention back to their arm-wrestling match, not wanting to let such a rare opportunity go to waste.

As they began their struggle, each pushing against the other with all their might, he reveled in the feel of her soft skin against his own. Their breath mingled together in warm clouds, heightening the senses. Despite her obvious strength, there was something about her demeanor today that made him think he could win. And win he would - if only to prove himself to both her and himself.

Despite the thrill of their arm-wrestling match, Childe couldn't help but notice Lumine through the glass, her pussy glistening in the dim light. It was a sight that ignited something primal within him, making his cock ache with need. As he wrestled against her, his gaze kept drifting downwards, fueling his desire even further.

Their bodies were pressed together so tightly that every breath, every movement sent waves of sensation coursing through them both. He could feel her heart racing beneath his palm, and it only served to drive him harder. This was what he lived for - the thrill of battle, the chance to conquer and claim whatever prize presented itself... even if that prize happened to be as intoxicatingly alluring as Lumine herself.

Their match grew increasingly intense, with neither one willing to back down or admit defeat. Throughout it all, though, a part of him couldn't help but feel that he was forgetting something... That nagging sensation came rushing back when Lumine leaned in close and whispered huskily into his ear.

"You're... enjoying this, aren't you?" She asked, arching an eyebrow suggestively. The tone of her voice was flat but nonetheless accusatory. It brought him back to reality with a start, the truth of his desires hitting him like a slap across the face.

His hand went limp on her arm as they broke apart, their faces mere inches from each other. He could feel himself growing hard once more, but not from lust this time. Anger welled up inside him, boiling and churning within his gut. "

Oh, don't I know it? A moment of weakness, perhaps? But fear not, Ojou-chan," he said with a playful grin, "I can keep my urges in check..." His words trailed off as he glanced at the device in his hand, realization dawning. With a growl, he hurled it against the wall, sending it clattering to the floor in a shower of sparks. Then, before she could react, he seized her wrist, pulling her closer still. "But if there's one thing I cannot abide, Ojou-chan," he hissed venomously into her ear, "it's being played."

Their breath mingled together again, each ragged gasp a testament to the building tension between them. As he held her gaze, a strange mixture of anger, desire and something else entirely flashed in his eyes

Childe stared deep into Lumine's eyes, his own burning with intensity. He focused all his willpower on overwhelming her consciousness, bending her to his command. Her body felt warm and inviting beneath his touch, and her scent intoxicating. In that moment, he knew that he could make her do anything he wanted.

With a flicker of his fingers, he began weaving a complex pattern in the air in front of her face. The symbols spun and danced, drawing her attention like a moth to a flame. His voice became soft and soothing as he whispered words of command, guiding her mind deeper into the realm of hypnosis.

Lumine found herself unable to resist his spell, her eyelids growing heavy and her focus drifting away from reality. She felt lightheaded and disoriented, yet oddly at peace. Slowly but

The power surged through him, an almost physical sensation as Lumine succumbed to his control. With each passing second, she grew more pliant, more willing to obey his every whim. And what whims they were... As Childe gazed upon her ensnared form, he realized just how deeply he desired her. Not just sexually, but in a way that went beyond the physical. He craved her submission, the taste of her obedience on his tongue.

His hands slid up her arms, fingers curling gently around her shoulders. "Open your eyes, my pet," he murmured, forcing himself not to tear off her clothes there and then. When she complied, her expression was one of trust and desire mingled together, and it sent a shudder through him. His control wavered briefly, the urge to claim her right then and there almost overwhelming.

With a soft chuckle, Childe leaned in closer still, his lips barely brushing against her ear as he whispered huskily, "You know that's not how it works." He paused for dramatic effect before adding teasingly, "Now, if you wanted to give them to me... or take them off and hand them over... I might be more inclined to accept such a generous gift." His hands slid lower still, caressing the soft skin of her upper chest as he waited for her response.

With a small, shaky breath that sounded more like a moan, Lumine slowly lifted her arms and reached behind her back to undo the clasp on her bra. As it fell away from her chest, revealing her perky breasts for his taking, Childe felt his control slip further still. His desire overwhelmed him; he could barely contain himself as he leaned forward, pressing his lips against her neck and groaning into her skin.

"That's it, my pet," he whispered hoarsely, hands moving lower still to slide between her legs. "Let me see what I can do to make you feel good." His fingers found their target easily enough, sliding inside her wet folds with ease as she arched her back into his touch.

Childe's eyes widened in delight as Lumine reached back and slipped her panties off, holding them out to him with trembling hands. He took them eagerly, raising them to his nose and inhaling deeply before burying his face in the lacey fabric. With a satisfied moan, he threw the garment aside and positioned himself between her spread legs once more.

His fingers returned to their work, thrusting deeper and faster as he took advantage of her hypnotic state. She cried out his name, the sound filling the air like sweet music to his ears. As her body tensed and convulsed around him, he increased the pace, determined to bring her to her peak before claiming his own release.

As Lumine's orgasm finally washed over her, wracking her body with pleasure, Childe kept up his relentless assault on her senses. When she had finished shuddering beneath him, he withdrew his fingers, gaze fixed intently on her swollen folds. "Now," he breathed huskily, voice thick with desire, "tell me how old you are...and show it to me." His tone was commanding yet gentle, almost coaxing as he urged her to comply.

Lumine's breathing grew ragged as she struggled to obey his command, her body still tingling from the pleasure he had wrought. With trembling hands, she slowly spread her legs wider, revealing her achingly tender flesh to him. "I... I am twenty-three years old," she managed to say between gasps for air.

Her eyes remained fixed on his as if willing herself not to look away, daring him to object or criticize. But Childe only smiled in response, a wicked glint in his eye as he reached out and caressed her inner thigh with the pad of his thumb. "Very good, my pet," he purred, his voice smooth as silk. "Now show me how much you want this." His free hand slid between her legs once more, two fingers finding their target easily.

His fingers began to work against her again, pressing deep into her warm core as Lumine arched her back in response, moaning his name. Her lips parted, breath coming in ragged gasps as she felt the building pressure within her grow unbearable. She struggled to focus, trying to will herself to hold it back, but Childe's touch was too expert, too persuasive.

With a final gasp, she released the urine, peeing directly onto his waiting hand. The hot liquid flowed over his skin, dripping down his wrist and onto her parted lips. With a shudder, she closed her mouth around his wrist, drawing the last of the pee into her mouth before swallowing. Her eyes locked with his as she tasted the mix of sweetness and saltiness, and for a moment, they were the only things in the world that mattered.

Releasing a satisfied moan, Childe gripped her head firmly, guiding his aching length to her lips. As she opened her mouth eagerly, accepting him without hesitation, he thrust deep inside, feeling the wet heat of her tongue and the tightness of her throat around him. Her eyes rolled back in ecstasy as he began to move roughly within her mouth, each thrust accompanied by a low grunt.

His hands gripped her hair fiercely, keeping her pinned down as his hips bucked and twisted wildly, seeking release from the oppressive tension that had built up inside him. The feeling of her lips and tongue sliding over his cock was almost too much to bear; he could feel himself getting close, on the edge of losing control entirely.

As the pressure built within him, a growl rumbled low in his throat. Lumine's warm, wet mouth felt incredible as it tightened rhythmically around him, driving him wild with need. With one final thrust, he let out a primal cry, pulsing inside her mouth as hot, salty seed spilled forth, filling her mouth to overflowing. His legs trembled, his muscles tensing as he fought to remain upright despite the dizzying pleasure coursing through him.

Slowly, the waves of ecstasy subsided, leaving him spent and panting heavily. When at last he regained enough control to speak, he leaned down to whisper hoarsely into her ear, "Well done, Ojou-chan." A hand moved to cup her cheek gently before running through her hair, mussing it playfully. "That... was excellent." He paused, considering

Childe leaned in close, his voice soft and husky with desire. "But do you know what would be even better?" He smiled wickedly. "If we could make this kind of magic happen outside the lab." A shiver ran down Lumine's spine at his words, goosebumps forming on her skin as she wondered what he meant.

"What do you mean?" she asked hesitantly, her heart racing in anticipation and fear. "Outside... where everyone can see us?" Childe chuckled darkly, his eyes glinting with mischief. He nipped at her earlobe teasingly before answering. "Oh yes," he purred, "imagine how much fun that would be."

His hands slid down to cup her rear, squeezing gently. "And just think of all the things we could do... the places we could go..."

The idea made Lumine feel both thrilled and terrified in equal measure. She had never been one to conform, but the thought of flaunting their relationship so openly sent a jolt of adrenaline through her system. As she considered it further, she found herself growing increasingly aroused by the thought. She turned her head to nip playfully at Childe's neck before whispering, "It sounds... deliciously naughty." Her fingers danced across his chest, tracing intricate patterns as if to say she was game for anything he desired.

"Naughty?" he repeated mockingly, pretending to be offended as he pulled back slightly to look at her. "I assure you, my dear Lumine, I am quite accustomed to such things." His voice dripped with false innocence as he grinned wickedly. "But perhaps," he continued, moving even closer once more, his breath hot against her ear, "you are not as familiar with them? Hmmm?"

His hands slid lower still, finding the hem of her borrowed t-shirt and raising it slowly, revealing the smooth skin of her stomach beneath. "Would you like to learn more about how naughty things can feel between us?" he asked huskily, thumbs now teasingly close to her lace-covered nipples. "Or would you prefer to keep playing in here..." He gestured vaguely downward "...with these?"

"Well, Ojou-chan," Childe purred as he lowered his head toward hers, their faces mere inches apart, "the choice is yours." His eyes darted momentarily toward the door before returning to meet hers, a challenge dancing in their depths. His hands moved up her sides, slipping under the thin fabric of her shirt until they cupped her breasts through her bra, squeezing gently. "Remember, there's no shame in wanting this... only in giving in too easily."

As he waited for her answer, he let one corner of his mouth curl into a wicked smirk, anticipation burning bright within him. The knowledge that he held all the cards, that she was truly at his mercy, filled him with an intoxicating power he had never experienced before. It made it easier for him to pretend that this was nothing more than a game... when in reality, it meant

Childe could feel her uncertainty, the brief flicker of fear that crossed her features as she struggled with her decision. He resisted the urge to push further, to force her hand; instead, he contented himself with savoring the sensation of holding her power in his grasp. For now, it was enough just to know that she was his to command... and that he alone could unlock the secret desires buried deep within her.

As their faces hovered mere inches apart, he allowed himself a small smile, admiring her courage even in the face of such overwhelming temptation. Her lips parted slightly, eyes shining with a mixture of determination and desire that sent shivers down his spine. "I," she breathed softly, her voice trembling slightly, "want to learn more." Her hands moved tentatively to encircle his neck, drawing herself even closer still.

He held her gaz
