Chương 16: How Can I Do That!? I'm Your Sister! [R18]

"Here, show me how you make a kiss feel amazing," Lucian whispered, his voice laced with dark amusement.

His eyes twinkled with mischief, daring her to match his intensity.

"But I-" Isabella began, her voice faltering under his expectant gaze.

"Just do as I did, Isabella," he interrupted smoothly, his tone both commanding and coaxing, "pretend you're sucking on an ice cream."

Her face flushed with a mix of embarrassment and anticipation, but she nodded hesitantly. "Ok..."

With trembling hands, she leaned in, her heart pounding so loudly she was certain he could hear it.

The proximity of his body, so close and commanding, made her nerves flutter uncontrollably.

She pressed her lips against his, the sensation sending a jolt of electricity through her.

His lips were soft, yet firm, and she could taste the sweet, intoxicating smoothness of him. It was overwhelming, a heady mix of desire and uncertainty.

Her breath hitched as she let her tongue flick out, lightly stroking his lips, feeling the warmth and the forbidden thrill of what she was doing.

She hesitated for a moment, unsure of herself, but the dark, encouraging look in Lucian's eyes urged her on.

Teasingly, she probed the seam of his mouth, not expecting him to respond so willingly.

But to her surprise, his lips parted, inviting her in without resistance.

As her tongue slid inside, exploring the depths of his mouth, she was met with a warmth that made her skin tingle.

His mouth was a tantalizing mix of silk and spice, rich and decadent, like something she should be ashamed of craving but couldn't resist.

The taste of him was addictive, sending waves of pleasure coursing through her.

Isabella's initial hesitation melted away as she became more confident, her tongue exploring his mouth with increasing boldness.

She could feel his breath mingle with hers, hot and heavy, and it only fueled her desire further.

The sensations were overwhelming, a heady mix of pleasure and fear that made her body tremble with need.

Her pink tongue slid over his, their saliva mingling as she found herself drowning in the intoxicating taste of him.

Slurp~ Slurp~

The feeling of his tongue against hers was overwhelming, and she found herself instinctively seeking out more, their tongues intertwining as their bodies pressed even closer together.

As she kissed him with a fervor she didn't know she was capable of, Isabella could feel something stirring within her.

A strange, dark yearning, a hunger that she had never felt before.

She wanted more, needed more, and despite herself, she found herself greedily deepening the kiss, the taste of him flooding her senses until there was nothing left but the raw, primal need that pulsed through her.

Lucian hands tightened around her hips, his body responding to hers, their tongues dancing together in a tangled mess of heat and passion.

His hands slid up her sides, teasing the sensitive skin of her breasts, and a low, sensual groan rumble in his chest.

She could feel the heat building between them, so she reached up and clutched his hair tightly, pulling him deeper into the kiss, desperate for more.

His hands slipped down to the curve of her slim waist, his fingers grazing her stomach, setting her nerves on fire with every touch.

She arched her back, her body arching into his hands as her hips ground into his, and the tension between them grew so taut it was almost unbearable.

Just as her body began to ache for more, he slowly pulled back, leaving her breathless and trembling, her mouth swollen and slick with their mingled saliva.

His eyes, dark red and hooded, watched her with a raw intensity, and she felt a surge of something strange and forbidden wash over her.

"Do you think you're ready for more, my dear sister?"

As the words slipped from his lips, she could feel her resolve begin to crumble, her body yearning for something she couldn't quite put into words.

Before she could answer, he leaned in and captured her lips once again, his mouth moving against hers in a way that made her stomach tighten with desire.

As his tongue plundered her mouth with a fierce, animalistic hunger, his hands began to move, sliding down to cup her ass, squeezing the firm, rounded curves in a way that left her gasping into his mouth.

She could feel her breathing becoming erratic, her body trembling under his touch as he continued to plunder her mouth with a primal, animalistic need.

Lucian hands slowly entered her gown, sliding upwards until they reached her bare breasts.

At the sensation of his fingers rubbing her nipples, Isabella broke the kiss, gasping for air as her body continued to respond to his touch.

"W-wait... Br.. oghhh... brother! Don't..... not there..."

She tried to speak, but the feeling of his hands caressing her nipples, his fingers rolling them between his fingertips, made her lose any sense of reason or decorum.

A constant ache began to grow deep within her as his nails scraped against her soft flesh, sending waves of heat through her.

As he continued to tease her nipples, his tongue flicked out to lick the soft skin of her neck, his lips brushing against her ear, leaving her gasping and moaning in response.

"H-how dare you defile me this way! I am not some wh*re you can toy with!" She managed to spit out, but despite her anger, she could feel her body responding to his touch, her nipples hardening under his fingers as her juices began to trickle down her thighs.

But instead of stopping, he just grinned and slid his hand down to her lower region, and began to touch her slit through her gown.

The sensation was overwhelming, and she couldn't help but gasp as his fingers explored her with a skill that left her quaking in his arms.

"You don't sound like you're in much of a position to talk," he whispered, his voice low and husky, "even those wh*re does not show such expression and sensitivity as you."

Isabella felt a hot flush of shame wash over her, but she couldn't stop the moans of pleasure from escaping her lips.

As Lucian's fingers pressed deeper into her, she felt her body arching back, her hips grinding against his in a rhythmic motion.

She couldn't resist him anymore, and she felt herself give in to the overwhelming sensation of his touch.

She moaned as his fingers slowly slid inside her gown, touching her wet slit, his fingers curling around her sensitive nub in a way that sent sparks of electricity through her body.

"Wa-wait.... Some.... something strange seems to come out from there," she whispered breathlessly.

Squelch~ Squelch~

He didn't seem to listen, his fingers continuing to slide in and out of her in a slow, relentless rhythm, his thumb brushing against her swollen clit with every thrust.

Sounds of their lovemaking echoed around them, a symphony of lust, sweat, and desire.

She could feel herself growing close, her body tightening as his fingers pumped in and out of her, every movement filling her with a sense of want, of need, that she had never felt before.

In a final burst of pleasure, her body convulsed, a wave of ecstasy crashing over her.

Her head was spinning, her body trembling with the sheer force of her release.

Ahhhhhhhh~

With a loud scream, she collapsed in his arms, utterly spent and unable to move.

Panting hard, she finally came to her senses, slowly slipping from her brother's lap, and landing on the floor.

Her heart was racing, her body shaking and twitching as she struggled to catch her breath.

"How does it feel to come from your brother's fingering, dear sister?" Lucian's husky voice whispered in her ear, his lips pressing against her neck, his tongue tracing the curve of her jaw.

She didn't reply, her head still swimming in a haze of pleasure, unable to speak or even think.

"Now you should please me too," he said bringing his bulging to her face, "suck my c*ck! Put it in your mouth!"

"N-no! How can I do that?! I'm your sister!"

"Forbidden relations," Lucian chuckled, "is an exciting spice in life. Come on, it won't hurt you! It will be our special moment, our little secret!"

"And don't you need my help to break off your marriage? Besides your wet cave down there seems to want it a lot more than you're letting on."

"..."

Looking at her face flushed with embarrassment, Lucian sneered.

"There's no need to be shy, my dear sister, your body tells me how badly you crave it."

"How can you say such vulgar words to your sister!?" Isabella hissed, her anger rising to the surface.

Lucian simply leaned in, his eyes glittering with amusement.

"My dear sister," he said, his voice a seductive purr, "you were just grinding your body onto me in the most lascivious way. Do you really think you can feign innocence now?"

"I-I did not mean-"

"Of course, you do. You want it just as badly as I do."

As he spoke, his fingers gently cupped her chin, tilting her face up until their eyes met.

Her stunning face flushed with shame, though there was an unmistakable flicker of something deeper — an unbidden desire that she couldn't fully suppress.

"Don't look at me like I'm the one to blame," Lucian sneered, his voice dripping with mockery.

A wicked grin curled his lips, his eyes gleaming with malevolent amusement.

"You know, nothing comes for free in this world. If you want my help, you'll have to offer something in return. And you know exactly what I want, don't you?"
