As my sexual relationship with my brother continues,

I finally had my first sexual experience...

I mean, me with Kaoru...

But having sex with him wasn't enough to satisfy me.

That's why I...

B-Bro, I want it...

Make me come...

Mako-chan's Development Diary

You mean, you want this?

You just had sex with your boyfriend a moment ago.

I can't believe you're craving another man's cock now.

And what's worse is he's still here in our house.

Y-You see, Kaoru...

...has never had sex before so he's not used to it yet.

To be honest, I-I haven't reached orgasm yet...

I knew it...

I anticipated that much from him.

Since it's a request from my younger stepsister, I'd love to grant it.

We don't have any rubber, though.

I guess I'll just have to bail out.

Just do it with your boyfriend when he goes back.

N-No way! Sex with Kaoru won't be enough...

It's okay...

We can do it without a rubber...

I want your cock!

I'll put my dick inside if you insist,

but there will be a condition.

Whenever we fuck from now on,

it always has to be bareback.

N-No way...

Should we stop, then?

Don't!

W-We can do it bareback from now on!

I want your thing right now!

What a hopeless girl.

Here it is!

Here comes my brother's cock!

His ginormous cock!

Oh, did you have a mild orgasm just from the insertion?

Wow, it's thick!

It's stiff! It's long!

Ah...

Huh?

A-Ahh... It's gonna slide out...

There!

Ohh, this is great!

Your pussy feels so nice and hot!

My pussy is getting pounded so much!

It's reaching all the way in!

It feels great!

Aren't you moaning louder than usual?

Do you want your boyfriend to hear you downstairs?

Y-You're wrong!

I should lend you a hand, then!

Huh!? Ahh! Ahhhh!

What's happening here!?

My brother's cock feels too good!

It's sliding even way deeper than earlier!

I'll start walking just like this.

Huh? Ahh, no...

Wait!

It's slamming into me!

The way you tighten up on my every step is hilarious!

Your ass cheeks are easy to hold

so I can fuck you in any position with ease!

If we keep having intense and rough sex like this...

I reached climax from having sex with my brother once again...

There you go...

I'm gonna fuck you from behind this time, Mako.

Grab tightly onto the doorknob.

Ahh! No, we can't!

Not here!

What if Kaoru comes back!?

We can't!

What do you mean we can't?

Aren't you squeezing me so tightly!?

Th-That's...

Huh, footsteps?

Bro, p-pull it out already!

Kaoru is coming!

Oops, this certainly would be risky...

Makoto, I'm here. I'm coming in.

W-Wait, not yet!

B-Bro, hurry up...

Hide in the closet...

Right, I'll pull it out slowly...

Makoto? Are you okay?

Y-Yeah...

J-Just give me a moment...

He'll catch us... Kaoru will find out!

Huh, okay? I'll wait.

Kaoru, I'm sorry...

Makoto? Are you sure you're okay there?

If you don't answer him right away,

your boyfriend will worry and open the door!

We're just a few centimeters apart.

Although Kaoru is right behind the door,

my brother is messing with both my mind and body!

Kaoru, I'm...

..m-masturbating right now!

Huuuh!?

It's because the sex we had earlier felt great...

I couldn't wait...

...until you come back!

M-Makoto, I wanna see you masturbating...

Y-You can't! I-It's embarrassing for me!

Makoto... Makoto!

I'm sorry, Kaoru... Ahh!

You're just right ahead, but I'm doing such a thing...

O-Ooh! It's too long!

Hey, Makoto... What do you fantasize about while masturbating?

Hey, your boyfriend is asking how you masturbate.

Let him know!

Wow! It's so thick!

I fantasize about...

...getting railed with your thing!

Makoto is using my cock as her fap fuel...

...while pleasuring herself so intensely!

This is way too lewd!

This is turning me on more than our sex earlier!

Makoto, does my cock feel good?

Yes... Yes!

Wow! It's so thick!

Kaoru, your thing feels great!

Hey there... Aren't you shaking your ass too hard in front of your boyfriend?

Ahh! It's scraping my pussy!

Yes, it feels great!

It's thick and stiff!

This is totally different from what Kaoru has!

I'm about to come...

I'm gonna fill you up with a creampie!

M-Makoto, I'm almost there!

Yes, shoot out a lot!

I'm gonna come too!

I'm coming! Coming! Coming! Coming!

Coming! Coming! Coming! Coming!

I'm comiiiiiiiiiiing!

My pee is leaking out...

M-Makoto, I'm sorry...

I got the door dirty...

That's fine...

I got plenty dirty here myself...

Kaoru is just right ahead,

but my brother filled up my pussy with his semen!

I'm sorry, Kaoru...

You should go home now...

Huh?

I'm too embarrassed to face you right now...

I'm really sorry...

Let's do it again, okay?

Uhh, yeah...

Alright... See you...

Damn, Makoto is way too lewd today!

It's very nice to have a lewd girlfriend...

Let me go already!

Hey there, Mako...

You seemed to be feeling so good earlier!

Is it that kind of stuff?

Do you enjoy the guilty pleasure when your boyfriend might catch you?

Y-You're wrong, Ahh! Nooo!

Jeez, we may be step-siblings

but look at how hard your nipples are from getting fucked by your brother!

Just how lewd are you?

Ahh, not my nipples!

Look at how hard your pussy is squeezing.

Does it feel that good, huuuh!?

B-But that's because of your cock...

I-It feels so amazing!

Ohh? Right, I see it now...

In other words...

You love your boyfriend,

but you love my huge cock even more!

He's wrong! That's not true!

I love Kaoru! My feelings are true!

However...

Whenever I get pounded hard by my brother's huge cock,

I'm unable to think about anything else!

Come on, apologize to Kaoru!

Say you're sorry for having a slutty pussy!

I don't want to...

I don't wanna say something like that, but...

Kaoru, I'm sorry! I... I...

I have a slutty pussy that loves huge cocks more than you!

Well said, Mako!

That's the kind of girl you are!

You prefer whatever feels better, right?

This is awful... I was forced to say those things...

So why... Why am I...

...feeling good from thiiiiis!?

Alright, I'm gonna dump it in your pussy!

Make sure to swallow it with that slutty pussy of yours!

Creampies are amazing...

I'm sorry, Kaoru...

This is going to be

the last time I'm doing it with my brother...

I'll make sure it is...
