Special Guest! (4)

While my beloved older sister was busy sniffing the scent of my cock, I decided to check the analysis results on her.

Once again, her erotic status was quite brutal.

As expected, she had no sexual experience at all, and it was now confirmed that I had taken her virginity.

I changed the Sadist Beginner achievement among her list to off.

I could always turn it back on later if I felt like it.

Sniff♡… Sniff♡…

It had been a while since I ordered her to clean me, yet she was still mindlessly ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠glancing at me and taking little sniffs whenever she thought I wasn’t looking.

What an impudent bitch.

“Clean it properly.”

Only then did she pull her tongue out from between her lips and begin licking my cock in small, careful strokes.

At first she licked the glans and the smegma trapped between the foreskin, swallowing every bit as I shoved it against her mouth. Then she moved down the shaft, and finally to the hairy base. Tears gradually welled up in her eyes, drawing clear streaks ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠down her cheeks.

Was her pride hurting now after going completely crazy over my cock just moments ago?

Seeing her like this almost made me feel a little sorry.

After all, she used to treat me kindly sometimes.

But we had already crossed the line far beyond any point of return.

When she first clamped her thighs around my neck, I had gotten angry. In my aroused state I had choked her right back. The sight of her neck being squeezed was unbearably erotic, and my sadistic urges had surged.

There was no turning back now. She had also said unforgivable things to me.

I wondered how I should use those photos, videos, and recordings.

Unfortunately, my raging lust felt far stronger than any guilt.

And that lust was the dark, filthy desire to completely defile my own sister—my father’s biological daughter, the child my mother had carried in her womb—with the disgusting night-blooming scent of my cock.

While enjoying the feel of her tongue, I pressed my balls against her mouth as well.

This was the same mouth that used to pick fights with me at every opportunity.

This was the same face that used to look so satisfied while putting me down.

Now that mouth was completely hidden beneath my balls, and her pretty face was half buried under my cock.

Every lick made my balls feel like they were melting.

I waited leisurely for a long time, giving her the chance to savor every wrinkle.

Once the cleaning was mostly finished, my balls signaled that it was time again.

I locked her head between my thighs, grabbed her hair, and shoved my cock straight into her mouth. Then I leaned my full weight forward and thrust deep.

“…..! ………! …….!”

Her arms slapped weakly against my thighs, but they were pinned by my legs and couldn’t generate any real strength. Besides, ever since I gained the Pure Body, I had become far more durable.

Gluck♡! Gluck♡! Gluck♡!

My cock, which had vanished into her throat, erupted straight down toward her stomach. Because I had shot it so deep, my cock came out relatively clean.

But the moment I pulled out, I felt the semen surging back up from her throat.

My sister glared at me, but the intense contempt from earlier was gone. Instead her face was flushed red, her expression one of humiliated resentment.

With my cock still halfway in her mouth, I spoke without thinking.

“Sister… I love you…”

“……”

She turned her glaring eyes away, still holding my cock and cum in her mouth. Even so, with my dick stuffed between her lips she couldn’t actually look away.

“Sister… Don’t spit it out… That’s an order…”

As if trying to rebel at least a little against her damaged pride, she used her tongue to push some of the semen out through the gap beside my cock.

“…….What the fuck did you just do?”

She’s so fucking cute.

Her rebellious little act only made my cock throb harder. The way ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her tongue moved while coated in my cum felt incredible too.

I had said it because her behavior was so arousing and adorable, but she thought I was angry and became terrified.

“Mmm…. S-sowwy…”

She apologized while still holding my cock in her mouth. The rebellion vanished as quickly as it appeared; she quickly scooped the spilled semen back onto her tongue and pulled it inside.

“If you did something wrong, you need to be punished, don’t you?”

“Mmm… wha… pun… ish… ment…?”

“From now on, sister is my slave too… So if you misbehave again, I’ll shove something new into your ass every single time.”

“……”

“For now, let’s add one slave rule. Don’t ever try to take out anything I put in your pussy or ass without my permission. Understand?”

“Mmmph… th-that’s… too much…”

“Too much? Then should I just upload everything? I’m still recording, you know.”

“Should I spread the photos along with the cleaning you just did and the fact that you’re holding my cum in your mouth right now?”

Her face flushed bright red as fresh tears welled up in her eyes.

“Sowwy!.. I’ll do everything you say…”

I stroked her head as she submitted.

Even though her personality was awful and violent, she was still disgustingly beautiful.

I had thought she was a total slut, but she had actually been a virgin. And why the hell was her hair so silky? She dyed it all the time, too.

“I’m sorry, sister. I was too harsh today, wasn’t I?”

“But I couldn’t help myself. You’ll understand, right?”

“…Yes…♡”

“Still, seeing you hold my cum in your mouth like that is hot. So don’t swallow until I give you permission, got it?”

“…….Ugh…. Yes…♡”

I pulled my cock out of her mouth.

Chuuup!

Her lips sucked hard, as if trying to clean me one last time.

She suddenly seems like a caring slave sister.

I held the freshly pulled-out cock in front of her eyes.

“How does it look now? Does my cock still seem small?”

“…No…”

“Then why did you act so cocky saying it was small before?”

“…Because I… never saw one in real life…”

“Are you going to act cocky again?”

“..No..”

“Good girl. You can go back to your room now. But remember—don’t swallow.”

She kept avoiding my gaze but kept stealing glances at my cock as she answered.

“…Mmm♡…”

She twisted her thighs together to try to stop the cum leaking from her pussy, but she couldn’t prevent it from dripping down her mouth and legs as well.

Covering both her mouth and her pussy, she staggered out of the room.

A little more cum spurted from between her lips.

She really knew how to make me horny ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠again.

But at this rate, wouldn’t someone catch her like that?
