Mako! Good morning!

Good morning, Risa!

You too, Reina! G'morning!

Uhh... What's up with that?

He's doing self-study. What happened?

Oh, about that...

Kaoru's grades had always been poor.

Yeah.

So, Mako told him last time...

"It'll be nice if we can go to the same university!"

Oh-hoh! So, that's why...

And then... Listen to this, Risa!

Ah! Hey, Reina!

If he gets above-average marks

on every subject in the upcoming exams,

she will agree to have sex with him!

Ehh!? Mako... You are cruel!

No wonder why he's that desperate.

Men are such sad creatures.

But aren't you making things harder for yourself too, Mako?

Huh, why?

Well, aren't you a huge closet perv?

Huuuh!? That's not true!

Oh? I wonder about that...

Shut up!

Mako-chan's Development Diary

Uhh... I feel very drowsy...

How many cups have you had? Isn't that too much coffee?

Sorry... One more cup, please...

Huh? You're already asleep.

Perhaps the condition of getting above-average marks for sex was too harsh...

I might've really dug up my own grave here.

I plan to abstain from masturbation in wish of having things go well...

But maybe just a little...

I'll only touch myself a bit...

It shouldn't count as masturbation if I don't come...

It's been days since I last teased my clit.

This feels good...

My brother never laid his hands on me again since then.

No, that is a good thing!

This is bad! My own fingers are not enough!

What's this... Is Kaoru asleep?

Th-That's right.

He is tired so don't wake him up.

And you're secretly masturbating?

Huh!? Th-That's not true!

What was that? You're acting like a stranger.

As a big brother, I'll deal with my little sister's sexual frustration.

No, wait... Don't do that!

Kaoru might wake up!

Kaoru has always been a heavy sleeper. It's gonna be fine.

O-Oh no...

I knew it... My brother's fingers feel good!

He goes straight to where my sweet spot is!

Jeez...

Another man is getting you aroused in front of your boyfriend.

Makoto, you're a huge slut!

No... No, I'm not...

Don't worry.

I put some sedatives in Kaoru's cup.

You can moan as much as you want!

What's happening? It feels so good!

How did he even know that my ass is sensitive!?

No! I'm already about to come!

Haven't I told you this before?

Make sure to make your man feel good.

My brother's cock feels hard!

Aren't you better at this than last time?

Here's your reward for studying well!

Don't take a break! Suck it properly!

This is incredible!

His smell alone is already making me feel dizzy...

And he's even licking me inside my pussy!

This feels so good!

I'm almost there!

I'll also make you come while at it!

Hey there... Don't think that we're done here.

I'm not yet satisfied down here.

B-But...

Don't you want to keep going as well?

Huh?

I'm putting it in.

Th-Then, wear a rubber...

This feels great!

Having my pussy pounded deep inside

by his hard cock feels good!

You sure grew up with such a sexy body!

Every part of you feels nice and plump!

And even the slightest touch makes you moan!

Y-Yes!

Oh yeah, that sleep med Kaoru took in...

Its effect is immediate but mild.

He might wake up if you keep moaning loudly!

Huh!?

Here you go! Try keeping your voice down!

No way, this is bad!

I won't be able to take it if Kaoru sees me like this!

No way... No way!

Your pussy tightened up!

I bet the idea that your boyfriend might see this is turning you on!

I'm feeling pleasure from having another man inside me!

No, this is too much!

I can't keep my voice down any longer!

Look, Kaoru is gonna hear you!

He's gonna hear those vulgar moans!

This is definitely bad,

so why won't I stop feeling good!?

That's it, I'm almost there!

I'll shoot it inside you!

No! Not in front of Kaoru!

He's gonna wake up! He's gonna wake up!

He will wake up and see your o-face!

I'm comiiiiing!

It's not letting go...

That's a huge amount! You certainly would be pregnant if I never had a condom on.

My pussy has been twitching this whole time...

Sex feels great!

Your pussy is twitching.

You're still raring to go!

Don't you want it?

Come on, say it.

Y-Yes...

We still have more rubbers...

I know. I just need to wear one, right?

Okay, it's on.

I'll put it in bareback while pretending I'm wearing one.

It's so evil that it's exhilarating...

Ahh... It's going in!

Huh?

This feels way better than earlier!

Do you understand the situation, Makoto?

If Kaoru wakes up now,

he'll see my cock sliding in and out of your pussy!

He'll have a premium seat for the show!

No way!

No, If Kaoru sees me like this...

Your upper and lower mouths say different things!

I should reward your honest lower mouth!

My womb is getting crushed by his cock!

This feels incredible!

This pussy is about to come again.

You'll be having a wild orgasm.

If you don't want Kaoru to see it, we should stop right away.

But if you're fine with that, I'll keep piston-pumping until you come!

My pussy is barely holding on,

so if he tells me that...

I-It's okay!

It's okay even if he sees us! I wanna come!

Alright, Makoto!

Come from my cock just as you wish!

C-Coming!

I'm comiiiiiiiiing!

You're shooting your sperm inside me!

That was great...

Whoa! You squirted again!

Just how lewd can your pussy be?

Alright then...

There's a hole I haven't tried yet.

B-Bro... This feels so good!

Right... This tightness feels nice.

Haven't you been playing with it every single day?

Oh... I'm sorry, Kaoru!

I even took your girlfriend's anal virginity!

My brother has overtaken my entire body!

Even my butthole...

He's drilling the taste of his cock into it!

Her body is one huge cock sleeve!

I can get off with it whichever part I use!

Ahh... I see it now...

I am a cock sleeve!

My lewd body's sole purpose is to make cocks feel good!

Hey, Kaoru...

You should also try using her next time!

Yes, use me!

Put Kaoru's cock inside me!

But Kaoru is just a kid...

She's a second-hand woman that I already used!

Perhaps he won't make me feel as good as my brother does...

Jeez...

All sorts of fluids have flown all over the room.

You'll have a hard time cleaning around later.

I'll wipe your pussy for you.

The pussy of another man's girlfriend certainly has its own appeal to it.

Waiting all these years until you two

late bloomers started dating was worth it.

Kaoru...

I'm sorry for being a slutty girlfriend.

Damn... I fell asleep.

Huh? My notepad is wet...

Rise and shine, Kaoru!

Should we keep on studying?
