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

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

Yet she forced herself to maintain eye contact with him, 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 cried out.

Her confession sparked thrill in him, though it stirred guilt as well. He hadn't intended to impose such a limit on her. It was simply that... upon hearing her admission, jealousy surged through him unexpectedly.

As if his blood surged hotly, possessed by an odd compulsion, he yearned to claim Amara completely as his alone.

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

Oliver wished to avoid letting Amara believe he was angry, so he bent down to claim her lips in a fervent kiss.

His kiss blended depth with gentleness, causing Amara to soften completely beneath his caress.

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

While ravaging her mouth, Oliver's hands glided over Amara's silky skin, his movements shifting from rough to ardent as feelings flowed through every press of lips and hip.

Amara sensed she might climax at any moment, relishing the rush of feelings surging within her.

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 into her slick depths.

The heat radiating through her with each push.

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

She let out a sharp cry as her release hit intensely, her form shuddering from the intense peak that swept over her.

Before Amara could catch her breath from her high, Oliver released within her too, flooding her core with his scorching seed.

Her inner muscles clenched tightly around his length, milking him firmly and drawing out a massive burst of dense fluid into her, which triggered another wave of pleasure for Amara immediately after the initial one.

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

Amara's cries resounded across the space, mingled with Oliver's uneven panting.

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

Amara shattered the quiet by fluttering her eyes open and murmuring.

"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 softening member still nestled deep in her warmth.

"I don't know myself, honestly. I just felt possessive all of a sudden, wanting you all for myself." He paused 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?"

Amara giggled at his words. "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 earnest expression, Amara ran her fingers through his hair and replied, "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 planted a tender kiss on 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 grinned at his sister's warm display and declaration of affection. It touched his soul, brimming him with delight and contentment.

Suddenly, it hit him that this wasn't proper. Amara remained his sister, no matter what.

Though he was aware she reciprocated his feelings fully, Oliver sensed they shouldn't push their bond past the confines of their private space.

Doing so would surely spiral into chaos and spark a major uproar.

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

Spotting the fade in Oliver's smile and the dimming spark in his gaze, Amara furrowed her brow, puzzled by his sudden shift from joy.

Reflecting on her prior words, 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 statement jolted Oliver from his reverie, leaving him gazing 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 arms. Her eyes gleamed like stunning sapphires.

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 hands and stroked 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 answered 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 an intense, fiery embrace that stole their breath when it ended.

As their tongues swirled in perfect sync, Oliver found his mind drifting 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 his grandfather William giving him a substance meant to allow impregnating kin without repercussions.

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

'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 a night just before.

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

Yet for now, pondering causes wasn't the priority; rather, they focused on savoring and diving into their mutual cravings for love, fervor, and desire.
