Makoto
You worked very hard on our recent exams.
Yeah, thanks...
That's why, you see...
About that promise I made last time...
Ah, yeah...
My parents and brother won't be home tomorrow, so...
L-Let's have sex...
Ah...
A-Alright, see you tomorrow!
Makoto
N-No, bro...
Hey, Mako!
Don't end the call when we're just about to start!
But...
Ever since the day I gave my first to my older brother,
I've been unable to end this sexual relationship with him.
Ain't I a nice big brother?
I even gave our parents travel tickets as a gift,
so that my younger stepsister can have sex with her boyfriend.
Mako-chan's Development Diary
Thinking about it makes me nervous...
What should I talk about at moments like this?
I'm finally gonna have sex with Kaoru,
even though my sexual relationship with my brother is still going on...
A-Alright, I'm taking a shower!
O-Okay!
Stop this already...
Kaoru is upstairs...
Anyway, bro... Weren't you supposed to be out?
I'm here to make sure you two will be able to do it properly.
No!
And if I handle the foreplay,
you won't worry about Kaoru's skills or the lack thereof.
Huh?
Stop... A-Ahh!
Oh? You're quite wet.
Have you been looking forward to having sex with him?
Or did kissing me turn you on, huuuh!?
Oops, cover your mouth.
We won't get caught unless you moan too loud.
No, my voice...
Kaoru will hear me!
Oh, you're trying very hard...
How about if I do this, then?
Don't tease them at the same time!
My nipples!
If he stimulates me this much...
My pussy... Ahh!
I-I can't!
I won't be able to keep my voice down!
I'm gonna come already!
I-I'm...
Comiiing! I'm coming!
Whoops, that was close!
H-huh? Why?
Why are you actually trying to reach orgasm?
Aren't you about to have your first sex with your boyfriend?
Take a shower already and go back to your room.
I did it again...
I did a bad thing to Kaoru yet again...
And look over there.
I prepared sexy lingerie that can please men. Take it with you.
Sorry, I took a bit too long...
A-Ah, that's fine.
I'll go take a shower too.
Thank goodness...
Kaoru didn't find out what I've been doing with my brother...
I swear that's the last time...
I have to end this kind of relationship...
Ah, Kaoru?
I'm going in.
B-Bro!?
Why are you here!? Kaoru is just downstairs!
I already said I'll make sure you can do it properly.
A premium seat exists for these situations.
No way... Are you planning to hide there!?
He won't find anything out if you do everything right.
If you have no more questions, wear what's in that bag and get ready.
Makoto? I'm coming in.
H-How are they?
Kaoru is surprised...
He obviously will be
when I suddenly changed into this sexy lingerie.
This is embarrassing even for me.
What if he gets turned off by this?
This is all my brother's fault...
Well, it was a bit surprising
but I think you look very... uhh...
...cute in those.
Whoa...
Makoto?
What should I do? This feels so embarrassing...
I can't look straight into your face!
This is the first time you said I'm cute
and it made me happy...
I never knew being called cute by someone I love
can make me feel this happy...
But my brother is watching us...
M-Makoto...
I'm gonna have sex with Kaoru for the first time.
This is gonna be my real first sexual experience.
I can feel my brother's stare...
No, I have to focus on Kaoru right now!
Whoa, wow...
Looking at Makoto's boobs right now,
I can see how huge they really are.
Her puffy nipples and areolas are pink...
They look so lewd!
I never knew Makoto can make these sexy moans...
Girls' bodies sure are sensitive...
Ah, she has two moles in her armpit...
No matter where I touch her, she feels nice and smooth...
Whoooaaa!
So, this is what she looks like down here!
We've always been together as childhood friends,
but I keep finding out new things about her!
It's twitching every time I lick her.
My tongue is making her feel good!
Makoto, you're incredibly lewd!
Ooooh!
Kaoru's tongue makes me feel so peevish!
Right there... More...
Go a little harder...
If it was my brother, he'd be more...
No, I mustn't!
I shouldn't think about how my brother would've done things!
Please, Kaoru...
Put it inside me now...
I-I'm sorry. I'm not used to these things, so...
No, I should be apologizing instead...
Alright, I'm putting it in.
The fun is just about to start.
Huh!?
No way, is it...
...from that time?
Huh, why am I getting turned on!?
It would be bad if Kaoru finds out...
Makoto... Tell me if it hurts, okay?
Yeah...
Whoa, that's my pussy...
There goes my brother's fat thing!
I'm doing it with Kaoru right now,
but I can't take my mind off my brother's cock!
It's all in...
Are you alright, Makoto?
Yeah, I'm fine...
H-Huh?
Kaoru's cock feels different from my brother's...
My brother's thing is thicker
and it reaches deeper...
H-How could they be so different!?
My brother's cock would be...
...way more intense, just like that.
Huh!?
That's not right! Kaoru is the one I love!
Ahh, I'm coming!
Huh!?
No way...
Is it over already?
S-Sorry, Makoto...
It felt so good that I...
I-It's okay...
It felt good for me as well.
My brother would've lasted longer...
Umm, can I take a bath first?
Yeah, feel free...
It was his first time so that's to be expected.
As long as Kaoru is satisfied, I'm fine with it...
Kaoru lasted even shorter than I thought.
Bro!
It's your fault that I...
Huh?
Which one was better, mine or Kaoru's?
That's would be...
I knew it...
My brother's thing sure is very thick and huge!
...Kaoru's, obviously.
Hey there, what's up with the long pause?
Hey, stop!
Oh well, that's reassuring to hear.
Looks like your boyfriend's cock was able to satisfy you.
I just had sex with Kaoru and here he goes again, doing as he pleases!
I don't feel any shred of affection from him, unlike Kaoru!
He's treating me like a tool for sexual relief!
Nooo!
Hmm? It looks like it still wants more action...
Let's see...
I have to say no...
Stop...
It doesn't look satisfied to me yet, though...
I should get mad and tell my brother I don't belong to him!
Look, your pussy juice is leaking out.
Huh? Ahh!
This slutty pussy is feeling pleasure from the fingers
of a man who isn't your boyfriend!
Ahh, no! You're wrong!
I'm not feeling it...
He keeps teasing the spots where I love it!
Why does he know them?
No, I'm almost there!
I... I-I'm coming!
Whoops!
What's wrong, Mako? Your body is trembling.
It sounded like you said something earlier.
I can't hold back any longer from this...
I... want it... I want it!
Make me come...
