I stared at the girl lying on the bed.
My little step-sister, with her hair spread out on the white pillows and her eyes closed in peaceful rest.
Except she wasn't just Evelyn anymore.
She was also the System.
The thing that had guided me into this.
I looked down at the pale, smooth skin of her lower abdomen, at the small, intricate mark that had seen appear there.
The Crest, a symbol of my claim.
It pulsed faintly, a soft warm red.
Then, through the Crest, I heard a voice that was hers, but it didn't speak out loud— it came straight into my mind.
"Ahh~ Nii-san was so cool. He was so rough, and he looked so serious. I want him to do me again~."
So she was awake...
And was just pretending to sleep?
Evelyn's true thoughts kept going, not knowing I could hear every word.
'Guess I should release my scent again.
It will make him impatient and hard again, even if I'm 'sleeping' He'll have to come and take me again. It will be so good. I can even use the System's controls to make it even more intense. Ahh~ This is the best.'
A slow, creeping heat started in the pit of my stomach, quickly spreading through my body.
The scent.
I hadn't realized how powerful it was until just now.
It wasn't just a smell; it was like an invisible and addictive drug.
My nose twitched.
I inhaled deeply, and the air was suddenly thick with a sugary, maddeningly sweet aroma.
It was coming from her, and it was the very same smell that had broken my control earlier.
As if It was designed to drive me insane.
'He's sniffing the air! He's getting closer! I knew it! This is going to be so much fun.'
A vein throbbed on my forehead.
This little midget.
My mind screamed at the audacity of her plan, at the utter manipulation she was attempting right now,
All while pretending to be an innocent, exhausted damsel.
I pushed myself off the edge of the bed and moved toward her.
"Kyaa~ he's coming! Should I groan a little? Should I pretend to be drowsy? No, just keep my breathing steady. Wait for him to pounce!"
I reached the side of the bed where she lay.
Instead of climbing over her, I sat down gently on the mattress, just beside her hips.
I slipped one arm under her, supporting her neck, and the other beneath her knees.
Then, I scooped up Evelyn's limp body in one swift, easy motion.
She was light like feather.
I didn't put her back down on the pillows.
Instead, I carefully shifted her until she was lying face down across my lap, her pink hair falling over my thighs.
Her back was arched slightly, and her pure white, perfectly rounded ass was facing directly up toward my hands.
'Wait, what is this position? What is Nii-san trying to do? This is… different. Is he going to try and take me from behind? On his lap?'
'Oh, no. If he presses down, I won't be able to move. I won't be able to do anything. But... That actually sounds really, really good.'
A soft, delighted gasp escaped her mind.
I took a deep breath, fighting the urge to give in to her sweet manipulative scent.
I needed to establish control.
I needed to remind her who was in charge of this relationship here.
My hand descended, sinking into the soft flesh of her ass.
I squeezed hard, my thumbs pressing into the softness of her ass cheek.
"Ahh~"
A small, genuine moan of surprise and pleasure leaked from her lips.
'H-he's squeezing me! Oh, Goddess, this is amazing! Is he really trying to take me from behind? Ahh~ I can't wait.'
I raised my open hand. I kept my expression neutral, but inside, I was amused and a little annoyed by her unchecked desire.
She needed a lesson. A simple, easy to understand lesson.
My palm came down with a sharp thwack against her perfectly white, exposed right cheek.
"AHH- What are you doing?" Evelyn cried out, the forced sleepiness instantly gone from her voice.
I ignored her completely.
My hand moved to the other cheek and came down even harder.
Thwack!
Evelyn gasped and tried to move.
I felt a slight fluctuation in the air, a faint ripple of energy.
She was trying to teleport away, to escape.
'Huh.. What? Why isn't it working?!'
I immediately sensed the attempt through the connection of the Crest.
Before the teleportation could solidify, I focused my will, controlling the magic of the Crest on her womb.
It was a seal, and I commanded it to hold her in place. The faint ripple of energy vanished.
"What are you doing Nii-san? Let me go!" she shouted, trying to wriggle off my lap.
I grabbed both of her hands, pulling them behind her back and gathering them together with one hand, effectively immobilizing her in the humiliating position.
Her body was completely exposed and helpless across my thighs.
I leaned down, my lips brushing against the shell of her ear.
My voice was a low, firm murmur.
"You're becoming quite the mischievous kid, Evelyn~. A good Nii-san should punish his bad little sister when she acts out."
"Eh.. Punish? What have I done?" she asked,
I didn't answer with words.
I brought my free hand back down on her ass.
Slap!
"Ahh!"
Slap!
"Eek!"
Slap!
The sound echoed in the room, and the pure white skin of her cheeks began to bloom with a bright stinging red.
"So... Are you still going to pretend you're innocent after you gaslighted me into fucking you?" I asked, my voice still low.
She stopped struggling for a moment. Her breathing was ragged.
"Ah," she said, her voice small.
"So you found out?"
I stopped the rhythmic slapping. I moved my hand from her burning buttocks, trailing it up her spine until it rested on her lower back.
Then, slowly, I reached around until my thumb found the soft, sensitive bud hidden between her legs.
I rubbed it lightly.
She shivered violently, a deep, involuntary tremor.
"I just did," I confirmed, my gaze fixed on the back of her head.
"Right after I awakened there was a massage from Lilith about it. And the crest lets me hear everything inside your little head."
A smile, a truly wicked, knowing smile, stretched across her face.
"I wasn't trying that hard to hide it in the first place, Nii-san~" she admitted, her voice now a playful purr.
"So, it was expected that you'd find out eventually. You're too smart to stay in the dark forever."
'Tch- She's getting ahead of herself again.'
I decided to show her the true power of the Crest.
I focused my will, using the magical energy in the seal on her womb.
I commanded the Crest to increase the sensitivity of the area my thumb was pressing, her Clit.
The energy flowed, and her hips suddenly arched up.
I saw her eyes widen just before I flicked the sensitive spot hard with my fingernail.
The effect was instantaneous and explosive.
"Ahhhhhhhhh~" she moaned, a long cry that sent a violent shiver throughout her body.
She had cummed instantly, the sheer intensity of the feeling completely overwhelming her.
I picked her up immediately, turning her around so she was now facing me.
I settled her back on my lap, but this time, I arranged her so her legs were on either side of my waist.
My manhood, still thick and hard, was pressed between her thighs.
She settled onto me, her inner muscles instinctively tightening around my shaft.
It was a perfect fit, and the raw, intimate pressure of her body against mine sent a jolt of pleasure through me. It was too good.
Evelyn, still gasping from her sudden climax, reached down a hesitant hand.
Her fingers brushed the slick, rounded tip of my staff, tracing its shape.
I leaned my head forward, resting my chin on her shoulder. I sank my teeth gently into her delicate skin.
"Open your System Profile, Evelyn," I murmured.
"I want to see what your status is."
"Ahh~ Nii-san is so impatient," she sighed, a small smile in her voice.
"We can do that after you've taken care of your needs. The little you is still throbbing."
I gave her ear a small, firm bite.
"Do it. Now."
She giggled, in a delightful and innocent sound.
Her fingers continued to toy with the top part of my dick, making me groan low in my throat.
"Fine," she relented.
"But just for a peek."
A screen materialized in the air, floating just beyond her shoulder.
A pink screen, shimmering faintly, and at its borders, a gentle pink fire danced.
It was the System menu, personalized for her aesthetic.
My eyes scanned the text that appeared:
Name: Evelyn
Race: Primordial Demoness (Awakened)
Status: Ascended (Godhood)
Mana Proficiency: [Infinite]
Mana Capacity: [Infinite]
Strength: [SS+]
Agility: [SSS]

I stared at the words, my mind struggling to process the impossible.
Primordial Demoness?
Ascended Godhood?
Infinite stats?
I pushed Evelyn back slightly, my voice thick with disbelief and a sudden, sharp fear.
"The hell..."
