(0)Prologue

My sister comes into my room at night and asks for my permission to serve her.

My little sister is close to me in the futon and I can feel her heart beating.

She lets me harden her manhood by myself.

I am very happy about that and hope to serve you further.

(1) Day 1

She offers her first kiss, and her tongue twines even more fiercely at his request.

I had an inferiority complex about my small breasts, but I was happy to have them touched.

The first time I kissed her, I was inferior to her small breasts, but I was happy to be touched.

I was getting wet myself, and wished for more service, so I went in.

In the beginning, he had sex with her while keeping his voice down, but then he started to get excited and asked for sperm and impregnation…

I’m sure you’ll be able to understand what I mean.

I’m sure you’ll be happy to hear that.
It’s not enough to satisfy you, is it?
What should I do?
How about this?
Tsk.
What do you think?
That, yes, that was my first kiss.
What’s the difference?
…… Ugh ……, please don’t stare so much. I’m so embarrassed.

You can’t serve if you’re always embarrassed, right?
…… Wow, I get it. If you have any questions regarding where and how to get the best results, you can contact me at …….

I’m sure you’ll be happy to hear that.
I’m not sure what to say, but I’m sure you’ll understand.

Chug, chug, chug, chug, …… chug, chug …… haha, haha …… chug… ….

This is a real kiss …… chuckle …….

Chub, chub, chub …… mmm …… chub, chub, chub …… chub …… .

Phew …… haha, haha …… haha …….

When my brother wants me, as his sister, I feel I have to respond more.
So, too, it’s one more time.

(2) Day 2

Going to wake up my brother in the morning.

Whispering in his ear and kissing him when he doesn’t wake up.

Twirling your tongues around each other and telling your brother that you were actually awake and if he wanted a kiss, he should have told you.

To apologize for last night, she wanted to be treated to a morning glory and a service blowjob.

I’m sure you’ve heard of it.

Make sure your brother is feeling good and hitting on you at the same time.

After a lot of vaginal ejaculation, they kiss and make out.

Are you awake, big brother?
I’m sorry.
It’s morning, big brother. Please wake up.
Big brother. What a big brother.
If you don’t wake up, I’m going to kiss you.
I can’t help it.
I’m sure you’re not the only one.
How …… phew.

But I really do kiss him. It’s your brother’s fault for not waking up.
Chuchu…… chuchu, juchu! Chuchu! Chuchu, chuuuuu!

Chug, chug, chug! Chug, chug, chug, chug!
I can’t get up, can I? I’m a troubled big brother.
If this happens, …… is one more time. ……

Chug …… chug …… chug …… chug …… mmm!

(3) Day 3

Giving a massage to my brother in bed at night.

She confesses her feelings for her brother, gasping as he asks for her.

Shedding tears of joy at being accepted by her brother, and having even more intense sex.

She cries out for love and wants a baby.

I love you, I love you, I love you! Oh, brother! Aah! I love you so much!
Oh, to my brother! Aah! I want to serve you a lot, yes! I want to make him feel good!
I’ve been thinking that, but it feels so good! I’m being so selfish!
I’m so selfish!
I want it. I want to have a baby with my brother!
Baby, baby, ahhh! I want it.
I’m sorry for being a selfish sister. I’m sure you’ll be happy with the results.
Please give me the right to have a baby! I want to have a baby, I want to have a baby! My brother’s! Ah! My brother’s baby!
I want to have my brother’s baby! I want to have my brother’s baby!
I’m not sure what to say, but I’m sure you’ll understand.

Is this your way of saying, “Okay"?

(4) Epilogue

Report that she is pregnant and kiss her happily.
