HDXD: Omni Harem System-Chapter 264: My Sister’s Will Always Come First

Adam stood frozen in his dimly lit room, the faint. His heart pounded, not from the thrill of the Osmondra envelope on his desk, but from the sight before him.

There, sprawled across his luxurious silk sheets, was Priscilla, his older sister, his teacher, his fierce, infuriating tsundere mentor.

Her petite frame, barely taller than a child, glided against the fabric with slow, hot, and intimate movements, her naked skin catching the night light filtering through the mansion's walls.

Her small breasts barely rose from her chest, but her thick thighs and curvaceous hips pressed into the sheets, leaving faint damp marks that made Adam's throat go dry.

Her blonde drill ponytails splayed across the pillow, and her red eyes, brighter than Clara's, and Moca, as it was more sharper, and more beautiful like two of the most expensive ruby being just apart from each other, locked onto his golden eyes, a mix of embarrassment and arousal stemming from the two.

"P-Priscilla!?"

Adam stammered, his voice cracking like a teenager caught off guard. His eyes darted from her flushed face to her bare body and back again, his brain scrambling to process the scene.

"Um, what are you doing here!?"

Priscilla's cheeks blazed crimson, but her gaze didn't waver. She sat up abruptly on the ned, clutching the sheet to her chest, though it did little to hide her form.

"Tch, forget what you saw, you idiot!"

She snapped, her voice sharp but trembling with embarrassment.

"Just...just turn around and pretend this never happened, got it!?"

Adam blinked, his shock giving way to a nervous laugh as he rubbed the back of his neck.

"Kinda hard to forget when my own big sister is rubbing all over my sheets… or whatever you were doing."

He paused, his lips twitching into a grin as a reckless spark lit his eyes.

"I'd be lying if I said I didn't find this hot, though. Like, I am mildly aroused, even."

Priscilla's face went from crimson to molten lava, her red eyes widening as she spluttered.

"W-What!? You perverted brat! You are still the same horny fuck. Don't you dare say stuff like that!"

She yanked the sheet tighter, her ponytails bouncing as she turned her head away, clearly flustered.

"Oh, come on, Pris."

Adam said, his voice dripping with a playful, almost smug confidence as he leaned against the desk, arms crossed.

His eyes glinted with mischief, though a faint flush betrayed his nerves.

"You're acting like this is the first time we've seen each other naked. And beside I am a Lamia-based meta-human, you know, being this horny all the time is just in my nature, I can't help it, and even if I could why would I!?"

His grin widened, sharp and teasing, as he tilted his head, daring her to snap back, as he walk back closer to her.

And then said.

"But me aside, what is your excuse, big sis?"

Priscilla's face went molten, her red eyes flaring as she clutched the sheet tighter to her chest.

"Y-You shameless pervert!"

She sputtered, her voice a mix of indignation and embarrassment, her ponytails bouncing as she whipped her head away.

But before Adam could push the tease further, she pivoted, her tone slicing through the air like a blade.

"A-Anyway, how've you been doing since you left for this stupid human school? Probably making a mess of everything, as usual."

Adam chuckled, the tension easing slightly as he raised his hand to his mouth.

"Oh, you know, just the usual. Getting major headaches from those cultist fucks trying to stir up trouble. Apart from that, pretty good. School is a drag though, you could say, I was sold a different picture from initial expectations, but I'm managing."

His grin softened, as his eyes began searching hers.

"Me aside though, I must asked, what about you, Pris? How've you been holding up in the Monster World without me to annoy you?"

Priscilla huffed, crossing her arms over the sheet, her scowl deepening.

"Tch, none of your business, you nosy brat! I've been perfectly fine, thank you very much. Don't think I'm sitting around pining for you or anything stupid like that!"

Her voice was sharp, but her flushed cheeks and the way her eyes flicked away betrayed her. She was trying too hard to sound indifferent, and Adam knew it.

He laughed, a warm, rumbling sound that filled the room.

"Good to know you haven't changed even a bit, Pris."

Before she could snap back, he stepped closer, his hand moving almost instinctively to ruffle her hair, his fingers sinking into her blonde curls.

"Still the same grumpy and loving big sis, I remember, hehehe... Never stop being you?"

Priscilla froze, her cheeks flaring again as his hand patted her head.

"S-Stop that!"

She barked, swatting at his hand, though her movements lacked conviction.

"I'm not a child, you idiot! I'm vastly older than you, you know! Show some respect!"

Her voice was indignant, but the way her eyes softened, just for a moment, told a different story.

Adam's grin widened even more, there was time when he looked up at her, now he down at her, she protected him more than anyone else, now he will do the same, for her even ending the world would be in Adam roaster of thing she would gladly do just to protect this woman and her happiness, but in his mind, a quiet thought flickered.

'On the surface, sure, you're ancient, over thirty-seven thousand years old. But after that last dead-end before I reset the story, I lived to see the end of time and existence in our field.'

He didn't voice it, though.

That was a weight of pain he will gladly carry alone, a memory of a story long erased, where he had outlived everything, even her, given he was the end incarnate, she died by his hands. He against his will destroyed everything when he forcefully became the Lord of Darkness a slave of great power, and before the story concluded in the worst way possible, for uncountable and unimaginable amount of years, he had to bare witness to everything, alone, scared, and fill of anger unable to burst from the bottle of a prison that was his own body.

But now things where different. And he vowed he will never make harm to come to her or any of his other sister's.

'Thanks you for visiting me, just seeing you here was enough to brighten my day, I now feel less depress, I do miss home though.'

Adam said to himself, as he gently subtracted his hand from her head, his expression softening.

"It's nice to see you again, Pris. Honestly. I was gonna see you anyway, with winter break right around the corner."

Priscilla's scowl returned, though it was softer now, almost playful.

"Tch, didn't I tell you to stop treating me like a kid?"

She muttered, her voice laced with mock annoyance. Bit before Adam could pull his hand away completely, she grabbed it, her small fingers surprisingly strong as she placed it back on her head.

"There. If you're gonna do it, do it right, you dummy."

Adam blinked, as he was caught off guard, then burst into laughter, the sound echoing through the room.

"You're confusing, you know that?"

He said, his hand lingering in her hair, his fingers gently threading through her curls. For a moment, the air between them was warm, charged with something unspoken, her confused heart, and his melancholic amusement, and the undercurrent of something deeper, something neither was ready to name.

Not yet, at least. But as Adam finished laughing, Priscilla caught him off guard.

"Brat…

She said, causing Adam to respond to her by saying.

"Now, now Pris... Say my name, A-dam. Come on, both you and me know, I've long outgrown the whole brat thing, don't you think?"

Priscilla chuckled softly.

"You'll always be a brat. My brat. Adam the brat. Still… can I ask you something, Adam?"

Her voice dropped at the last part, quieter than the rest, but Adam still caught it.

"Sure... What can I do for the fair lady?"

He replied with a grin.

"Hmph ~ This fair lady has a request."

"A request, eh? As in?"

"Would you… ah…

She squirmed in the sheets, nervous, unsure of how to voice what was on her mind. Finally, she sighed, gathering her courage.

"Tonight… would you go on a date with me? There is a place I want to show you. People I've wanted to introduce you to since you were a kid. But back then… circumstances got in the way, and I held back. Ahh, look, it is nothing serious, you don't have to, ugh, what am I even saying? Forget I asked. Just pretend I never...

"Sure."

Her eyes went wide at his response, as she didn't even finish her full sentence, yet he said the words she wanted him to say the most.

"Wait… for real? You're not busy? Like no after school plans?"

Adam sighed, shaking his head with a wry smile.

"Why ask me out if you're not even sure of yourself? Pris, you really need to loosen up. Even if I did have plans, I would cancel them right away. I couldn't care less about anything beyond this. I'll always put you and the other first. So yes, II Priscilla Heartbreak, I am Adam Novel will gladly go on a date with you."
