There were other terms I didn't understand, like Lucky Pervert.
The only thing I could vaguely guess was that my good looks stemmed from the Sacred Body authority. Everything else was a mystery.
First, let's wash up.
The first step to not being the brother despised by my beautiful sisters.
'So many toiletries.'
As an only child, living in a house with this many feminine products is honestly overwhelming.
I casually pick up a shampoo bottle.
Zzap!!
"Ugh!"
What the hell? It's like static electricity, but… more dangerous. My whole body tingles.
Looking in the mirror, I notice my eyes glow crimson as I begin to understand what just happened.
[Insight (Crimson) activated]
[Stella's Forbidden Access Barrier Magic]
[Power: D]
[Duration: C]
[Activation Condition: When that idiot touches my stuff]
…
She put a barrier to keep me from touching her things?
I grab another bottle nearby, and this time, a stronger electric spell shoots through me.
Crackle!
"Guh!"
That… actually hurts.
Should I just give up on washing and leave?
"Oppa, is something wrong?"
Serena's soft voice comes from outside.
If it's Serena, maybe I can trust her.
"Do you know where my toiletries are?"
"Didn't you say you don't use that stuff…?"
…?
In a house with two sisters, I only wash with water…?
"…I decided to start washing properly from today."
A brief silence.
From the other side of the door, Serena speaks.
"You can use mine. The ones on the right are safe."
Since Serena says they're safe, it seems the previous "brother" and Stella must've clashed over this issue more than once.
Was not washing his way of asserting dominance?
God, that's disgusting…
Recalling the grimy white T-shirt, I scrub myself harder than usual.
[Lucky Pervert countdown: 58 seconds]
[You will touch your sister Serena's breasts]
…What the hell is this now?
The mysterious Lucky Pervert authority activates out of nowhere.
Touch my sister's breasts? Are you insane?
Since I don't see Serena as my real sister, I could theoretically view her as a romantic interest if we weren't "related."
But that aside, suddenly groping her? That's nonsense.
I decide to ignore it.
After drying off and stepping into the changing area, I realize Serena's still waiting for me.
"Serena? Why are you still…?"
"Hm? Oh, I thought there might be laundry…"
She's holding the filthy T-shirt I'd tossed aside.
"I'll take care of it."
I move before I can say something cheesy like, Don't touch dirty stuff with those pretty hands.
And then…
"Kyaa…!"
My foot slips.
"Whoa…!!"
As I slowly fall onto the soft, black-haired, purple-eyed sister beneath me…
I remember what Lucky Pervert is.
It's that cringeworthy trope from old rom-coms. You trip, end up in a compromising position with a girl, and it's both embarrassing and thrilling.
In reality, it's straight-up a crime.
The idea that a girl would blush and grow fond of you after an accidental touch? Utterly impossible…
'No way!'
I tense every muscle to avoid doing something stupid, but then…
'Wait…'
If she falls backward, she could get seriously hurt!
I wrap one arm around the back of Serena's head to protect her, while my other hand… firmly grabs her large breast.
Squeeze…!!
"…"
"…"
If I knead it twice… it's undeniable sexual assault…!
I immediately let go and stand up.
"Sorry."
"…I-It's fine. The floor's slippery, so we should be careful, Oppa…"
What kind of outdated trope is this, Goddess of Adult Games?
The guilt of doing something so crude to my sister makes my head spin.
I can't deny that, for a moment, the soft, explosive sensation of her natural breasts felt heavenly.
But at this stage…
My rationality screams that I shouldn't act on base desires with someone meant to be my new family.
'Maybe we could develop that kind of relationship later. But not now.'
I help Serena up.
"You okay? Anywhere hurt?"
"…Oppa… you've changed."
"…"
Technically, I'm a different person.
Despite what happened, Serena doesn't seem to dislike me.
Her sparkling purple eyes betray a curiosity she can't hide.
[Lucky Pervert activated]
[You slip and grab your sister Serena's breasts with both hands]
?? What the hell, there's no cooldown on this thing?
"Hold on."
This is a tricky situation.
My brain and my dick are simple. Just recalling the feel of Serena's breasts is enough to make me half-erect, practically bursting through my underwear.
That's a problem in itself. If Lucky Pervert triggers again in this state, I'm a full-on sex offender.
If I, the "brother," grope her breasts while visibly aroused, even Serena's kind heart would reach its limit, and I'd start my new life in jail.
That can't happen!
Is there no ON/OFF switch? I turn away and fiddle with Lucky Pervert.
"Oppa? Why the status window?"
"Well… uh…"
There! The Lucky Pervert font turns red.
That means it's disabled… right?
[Reality Manipulation Limit Released]
[Lucky Pervert activated!]
[10 seconds until you engage in slippery, creampie impregnation sex with Serena's pussy]
…Huh?
My brain freezes.
"Leave this to me."
Serena smiles, taking the clothes I was wearing.
"You might be late, so hurry up, change, and come down to eat together."
10 seconds.
Too short to think.
When I realize the text under Lucky Pervert isn't a "command" but a "situation that will inevitably occur," my only thought is:
I need to physically get out of here. Away from Serena!!
As I try to bolt, I slip again.
'Oh.'
Everything is according to Lucky Pervert's design.
It's not even a slippery spot, but I fall backward as if it's fate.
"Oppa! Are you okay!?"
If I instinctively grab Serena, that "absurd situation" might actually happen, so I grit my teeth and let my head hit the floor.
"Ugh! I-I'm fine."
"You just said 'ugh'…"
Hitting my head with a thud would do that.
It's a miracle there's no blood…
"Really, you're hopeless… I told you it's slippery."
10 seconds… passed.
Good. It must not activate if the user resists.
Sex? That's ridiculous.
Reality manipulation? Bullshit.
"Let me help you up, Oppa… Ah!"
Serena, reaching over me, suddenly slips and falls.
Even a comedy skit this forced would be called absurd.
But knowing the cause and effect, I feel a chill deep in my soul.
Serena's awkward fall is my fault.
And the fact that my erect dick, free from my underwear, is right beneath her…
It's an inescapable fate.
…!
"Ugh…!!"
…Slip…
Serena's definitely wearing panties, yet…
My dick slides perfectly into her body.
Slide, thrust…
[You luckily took Serena's virginity ♡]
What's with this infuriating system message?
"Ah… Ahh…?"
Serena freezes, unable to comprehend.
I'm in a similar state.
This makes no sense… It's impossible, but… Lucky Pervert manipulated the situation.
If you asked how far the manipulation went, there's no end to it.
For one, a woman's vagina isn't wide enough for an erect penis to "accidentally" enter during a fall.
Even if it were, Serena wasn't prepared for sex—no foreplay, no arousal.
Even if she were aroused and ready…
Accidentally penetrating during a fall is impossible.
All those "details."
Skipping every step, Serena and I are having sex.
For some reason, my rock-hard erection is buried in Serena's soaking wet pussy.
With her full weight, it went in instantly.
The only thing I can thank Lucky Pervert for is that, despite such a rough insertion, she's unharmed.
In reality… we'd be heading to the ER.
Even with a sensitive area like my dick taking her full weight, I'm uninjured and instead overwhelmed by the soft, tight sensation of her pussy.
I'm groaning from the unbearable pleasure.
"Ugh…"
Could Serena… feel the same?
At this horrifically contrived virginity loss, what's her reaction?
Leaning back, defenseless, Serena twitches with half-closed purple eyes.
"Ah…? Ah…? Uhh…?"
She doesn't seem to be in pain. If anything… she looks… enraptured…
When my dick twitches, her thighs tense.
The stillness works in our favor, as my record-breaking erection syncs perfectly with her pussy, locking us tightly together.
"Sere, I…"
What do I say?
Sorry? You okay? My mind's sluggish in this unprecedented situation.
Ignoring the urge to move my hips is the only thing I can do.
"…Let me… get up…"
Serena places her hands on my stomach, trying to assess the situation.
"Mm… Mmph… Ugh…"
Her hips lift.
Her tight, clinging pussy slides over my hypersensitive dick, feeling every nuance of the air.
"Ha… Haaa…♡"
Serena lets out a moan mixed with a dazed sigh.
It's too much for a virgin like me. My heart's pounding like crazy.
This is a woman's pussy.
The entrance is especially tight, gripping like it doesn't want to let go…
Her pussy, as if aroused before insertion, is overflowing with juices.
"I'll… get up…"
Slip♡
She slides back down, soaking wet.
Fate plays its trick as she slips again.
"Mmh… Mmhh…!?"
The heat of her steaming pussy radiates to my lower abdomen.
Even as a first-timer, I can tell her arousal is abnormal.
"Oppa, my hips… won't move…"
Serena, at a loss, slightly lifts and lowers her hips, moving in a way closer to sex than to pulling out.
"Stop…!"
I'm barely holding back here…!
"Ah… Ahh… Haa… Oppa…"
With a completely melted expression, Serena moves, whether to have sex or to pull out, I can't tell.
Is this Lucky Pervert's fault…?
Creampie, impregnation sex… Will it really go that far…?
"Don't move, Serena!"
I pull her close, wrapping her in my arms.
"Mmh… Mm, mmph…"
She gets even more aroused, trembling in my embrace as she climaxes.
I held her to stop her hips, but her pussy clamps down on my dick dangerously.
Unable to move, Serena asks,
"Am I… being raped by Oppa…?"
Is that something to ask in such a sweet voice?
I let my guard down. This world is an adult game…
I should've taken My Onahole Academy more seriously.
[Insight (Crimson) activated]
I see it. The threads of Lucky Pervert.
Red skulls connect red strings to Serena's head, arms, and legs, manipulating her like a puppet.
Those strings are tied to me too.
Holding Serena with one arm, I swing the other wildly, tearing the strings apart.
"Get lost!"
Like banishing a sea monster with sheer willpower.
I protected my sister…
From my own dick!
"…"
Serena, cradled in my lap, trembles in blissful afterglow.
'What do I do now?'
I think I'm screwed.
