NTR: Mommy Will Help You! 270. Why Am I Feeling So Much Possessiveness?

Those words caused Amara's heart to pound wildly. Her frame trembled with each powerful thrust from him, leaving her dizzy and breathless.

Yet she forced herself to hold his stare, her eyes growing wide while her mouth fell open slightly.

"Yes! I know... but it just happened... I'm sorry! I won't do it again! I promise! I'll only have sex with you... Only you... Please forgive me!" She pleaded desperately.

Her plea ignited a rush of thrill in him, though it also stirred a pang of remorse. He hadn't intended to impose such a limit on her. It was merely... upon hearing her confession, a wave of jealousy crashed over him unexpectedly.

As though his veins surged with fire, like an unseen power had taken hold, compelling him to claim Amara completely as his alone.

This sensation refused to fade. Rather than diminishing, it grew fiercer with every relentless pound into her.

Oliver wished to avoid making Amara believe he was angry, so he bent forward to claim her mouth in a fervent kiss.

His embrace blended intensity with gentleness, causing Amara to soften completely beneath him.

Their tongues intertwined in a blissful rhythm that enchanted them both.

While ravaging her lips, Oliver's fingers glided over Amara's silky flesh, his movements shifting from rough to ardent as his feelings surged through every press and plunge.

Amara sensed her peak approaching rapidly, relishing the waves of delight rippling across her form.

Every caress.

Every smooch.

The rhythm of his labored breaths.

The softness of his mouth.

The flavor of his tongue.

The thrill of his rigid shaft driving deep into her slick depths.

The heat blooming through her with each sway.

All these sensations were so exquisite that she couldn't hold back against the ecstasy flooding her thoughts.

She let out a sharp cry as her release hit fiercely, her entire being shuddering in the grip of that intense climax.

Just as her high began to ebb, Oliver erupted within her too, flooding her core with his scorching seed.

Her inner muscles clenched tightly around his length, milking him intensely and drawing out a massive burst of dense fluid into her, sparking another orgasm for Amara almost immediately after the first.

"Aaaaahhh!! Aaahhhnn! I can feel it... so much of it... pouring in me... I love you... my brother... mmnnn... uuhhnnn..."

Amara's cries resounded through the space, mingled with Oliver's uneven gasps.

For a few lingering instants, their forms stayed still. No words passed between them, each immersed in their private haven of rapture.

The quiet shattered as Amara's eyes fluttered open and she murmured.

"What got into you today, bro? I mean, your lovemaking has always been... amazing. But today you were more aggressive than before. It was incredible. But it's unlike you."

Oliver let out a soft laugh while resting atop her, his easing member still nestled inside her warmth.

"I don't know myself, honestly. I just felt possessive all of a sudden, wanting you all for myself." He hesitated briefly, thoughts swirling in his head before he went on, "Is it... jealousy? But I never minded other guys having sex with you or anyone else. Why does it feel different this time?"

His words drew a light laugh from Amara. "Maybe it's just love~. Because you truly love me."

"Hmm. Maybe. But I have loved you ever since we were kids. So why only now...?" Oliver wondered aloud, still baffled.

Noticing her brother's grave expression, Amara ran her fingers through his hair and whispered, "No matter what the reason might be, I'm not complaining at all. In fact, I like this possessive side of yours. It makes me feel even more loved." She pressed a tender kiss to him. "I want you to feel free to go crazy anytime. I'll always be ready to accept anything from you, my darling brother."

Oliver's face lit up with a grin at his sister's warm touch and heartfelt words. It touched his soul, surging him with delight and contentment.

Suddenly, a realization struck him that this wasn't proper. After all, Amara remained his sister.

Though he was aware she cherished him as deeply as he did her, Oliver sensed they shouldn't push their bond past the confines of their private moments.

Doing so would surely spiral into chaos, erupting into a major disgrace.

Not only for them, but his recent position and their blood ties would devastate the entire family.

Spotting the fade in his smile and the dimming light in his gaze, Amara's brow furrowed, curious about his sudden shift from joy.

Reflecting on her prior statement, she realized he was likely fretting over potential fallout from her invitation to claim her unbound.

"Hey, I know what you're thinking, bro. Don't worry, it won't become a problem between us, even if we become a couple openly."

Amara's declaration jolted Oliver from his reverie, and he gazed at her with bewilderment.

"What? How...? I don't get it."

"Simple. I talked to Mom and Dad about it before I came here. About creating a new identity, where I'm adopted into their family instead of born into it. A new history that can make you and me become legal lovers without worry."

Amara beamed a supportive grin while encircling Oliver with her embrace. Her gaze glittered like stunning blue gems.

Those captivating eyes brimming with affection, yearning, and optimism left Oliver powerless against the urge to kiss her anew.

Once their mouths parted, Oliver cradled Amara's face in his palms, stroking it softly. "That means we'll be together for the rest of our lives, won't we?"

Amara dipped her head and flushed pink. "Of course we will. Forever."

"And what about your boyfriend? Did you break up with him?" Oliver inquired, abruptly recalling Amara's existing partner.

Yet Amara replied calmly and soothingly. "Don't worry. We already broke up. But let's not talk about him anymore. I don't care about him since I have already decided to belong to you, my brother, Oliver."

With those final words, they affirmed their promise through a kiss, exchanging a profound, fiery liplock that stole their breath when it ended.

As their tongues swirled in perfect sync, Oliver found his mind drifting back to the source of his sudden ownership urge.

'Why? Why am I feeling so much possessiveness? Could it be... because of the effect of the drug?'

Oliver recalled how his grandfather, William, had given him a substance claimed to allow impregnating kin without repercussions.

'Did that drug have this side effect as well?' Oliver pondered inwardly while deepening his kiss with Amara, her soft whimpers enveloping him.

'It could be. After all, it is a drug created for the sole purpose of impregnating the blood-related women. But would the desire be so strong to the point of feeling this intense possessiveness?'

Still, Oliver noted it hadn't sparked the same urge toward his aunt Anna, with whom he'd shared the night prior.

'Hmmm... Too many questions, but not enough clues... Maybe I should ask Grandfather for details, after all.'

Yet for now, pondering causes took a backseat; the pair focused on savoring and diving into the mutual flames of love, fervor, and craving.
