【Ersis Rubber】The mistress who lives in a western-style house on the outskirts of town – developing shota nipples and twisting her sexuality

Concept
Have you ever thought about this when you were an adolescent and started to get interested in sex?

I’d like to be able to do such and such to my naughty sister.
But I’m embarrassed to let my friends at school know about it.

In this movie, you can have a sister who can make your memories of those days come true and give you “good things".
However, there is one condition that must be fulfilled in order for her to give you a “good thing".

It is to fall into the “nipple masochism".

The heroine of this story loves to see boys who are interested in sex become more comfortable with their nipples than with their cocks.
Every time you develop a sexual sensation in your nipples and remodel your body to feel good with them, you get to do something “good" with them.

This is why she gives you nipple development “homework".
If you’re not sure what you want to do, you can always ask your sister to do it for you.

The fifth work of the circle “Ersis Rubber♪" is
In order to fulfill the desire of the sister who likes boys who feel with nipples, she has to do the homework of nipple development.
I’m sure you’ll enjoy it.

But once you learn the pleasure of nipples, won’t your body be satisfied without them?

If you are a woman who has just reached puberty, you should be able to develop your nipples in a non-reversible way.
I like the idea of falling into a masochistic state of being more and more sensitive and craving to have my nipples tweaked, but
What I really like is when I get to do the “good stuff" that I want.
The moment when you realize that your body can no longer be satisfied without the pleasure of your nipples.

The moment you realize that you’ve gotten yourself into a position where you can’t go back and seek out nipple pleasure.

Background
I was on my way to a friend’s house in a neighboring town when I got caught in a heavy rain.
I rented a place to shelter from the rain at the entrance of a large mansion.

When I stopped to look at it again, it looked a little old, but it was a very nice house.
While admiring the size of the house, which was perfect for taking shelter from the rain, we took a short break using the stone steps as chairs.

I wonder what kind of people live here?
I don’t like it when people are scary.

When I was thinking about this, the front door opened.
There was a lady there with a very large height and very large breasts.

I’m sure you’re not the only one.

(Track 0: Introduction)

What’s wrong with you, you’re soaking wet?
Rainy Day?

Yes, on my way to play.
You were unlucky to get caught in the rain.

But with the way it’s coming down, I don’t think it’s going to stop, you know?

You’ll catch a cold if you’re soaking wet.
Hmm? It’s okay, it’s such a big house, but my sister is the only one who lives there.
It’s not a bother, you can just stay with me for a little while instead.

Yeah, I’ve been alone for a long time and I needed someone to talk to.

Can I?
Thanks, V!

Come on, this way.
Oh, I’ll have to get you a towel first.
Wait for me at the entrance, I’ll be right back.

I found a cute girl.
I don’t know how I’m going to corrupt her into a nipple masochist.

(Track 1: After the Story (Nipple Play, Hand Job))

Hey, do you… do you have fun every day?

At your age, you play with your friends and study together at school or cram school.

That may or may not be fun, it depends on the person.

It’s just that when you’re with your friends, you’re worried about what people will think.
There are things that you really want to do, but can’t quite do.

For example, sex.
You’re a boy, too.
You’re interested in sex and the adult female body, right?

Usually your friends make fun of you, so you’re more interested in big boobs and feminine scents.
I have to hide it from my friends so that they don’t find out.
I think it’s weird that both boys and girls are really interested in sex.

Hey you, you’ve been fidgeting for a while now.
What’s wrong with you, are you in the bathroom?

No, you’re not.
I don’t know, I’m just curious about your tits, they’re so big, right?
I can’t forget how soft they are, can I?
You’ve been staring at your sister’s cleavage all day. Didn’t you notice?

Oh, my God, you’re so cute.

I’m sure you’ll be happy to know that I have K-cups on my tits.
Look, count them, A, B, C, D…

It’s amazing, you still have them, they’re so big and sexy!
Hey, you want to touch…? Your sister’s K-cup tits.

Here, don’t hide them.
I’m the only one here, okay? Just be honest, okay?

——————————————————————-

Hmm? Do you want to see your sister’s tits in the flesh?
I’d love to see them, you don’t get to see K cup tits that often.

But no. No, you can’t.
I’ll show you my raw tits when I get to the point in my body where you can get more comfortable with my nipples.
I’d like to confirm once again that I call a man who can feel good with his nipples a “nipple masochist".

Hey, would you be willing to fall into nipple masochism for your sister?

(Track 2: Your reward for doing your homework (nipple teasing and sucking))

Hmmm…checking my homework, I’ll keep doing it.
Ah… the protrusions on my clothes, my nipples are standing out.

I couldn’t see them last time.

I wonder how sensitive it is…play with the nipple rings with your fingers…come…come…come…come…

If you were to properly pinch me from the areola and tweak my nerves a lot, this should still feel good…what do you think?

Also, if you keep pressure on your nipples with a bandage, it will also compress the nerves in your nipples and slowly develop them.
Now that your nipples are free from the bandage, they are in the most comfortable state.
You can also touch the nipple ring to the nerve at the back of the nipple.
I’m going to touch your nipples now, so get ready to feel good.

I’m looking forward to it.
At home, it would only hurt and make me think it felt good.

I’m going to give my sister Mizuki a gentle and very comfortable touch.

T… T… V.

You’ll be able to touch me.

Hey, do you want me to touch you?
Do you want me to touch you like before? Yes!
Do you want your sister to make your nipples feel good?

Would you be willing to fall further into nipple masochism for your sister?

(Track 3: Nipple masochism certification test (nipple masturbation, lotion handjob))

Your perverted body has been bouncing around since a while ago…

But my sister has my whole body under control, so no matter how much I flail, I don’t freak out…

I’m sure you’ll be able to do whatever you want with this situation.
What do you think? If I rape you like this.

Even though I felt like I was going crazy from the pleasure of doing what my sister wanted, perverting you.

You’re being held down by your big sister and there’s no escaping it.

You can’t shout out, but in this big house, even if you shout out to the outside, they can’t hear you.
Even if they did reach you, there’s not much traffic to begin with, so help is never on the way.

My fingers are stuck. Don’t stop masturbating your nipples.

Hey, you’re going to fall for the nipple masochism, aren’t you?
Don’t you want your sister to eat your virginity?

I’m not going to do anything you really don’t want me to do, okay?
If you don’t like it, I’ll let you go right now and send you home.
But if you don’t want to, I want to make you feel so good you’ll be writhing in agony.

If you don’t mind, I’d like to make you feel so good that you’ll writhe in pain.

Really? Do you want to be a nipple masochist?

Okay, that’s not how you say it, is it?
You want me to be a nipple masochist, right?

(Track 4: I’ve fallen so far for sex (nipple impatience, cowgirl, nipple masturbation))

How does it feel? How does it feel to be fucked in the pussy by your sister?

Really?
You know you’re missing something, don’t you?

だって、T… T… V.
弄れてないものね。

I’ve been working so hard to get comfortable with my nipples, and now I’m being taken advantage of.
I’ve been trying so hard to get my nipples to feel good, but I’ve been so frustrated by the lack of pleasure from my nipples.

Do you want me to play with your nipples?
You want to be ordered to play with your nipples by your sister Mizuki, right?

I’m sure you’re not the only one.
I wanted him to eat my virginity… I came all this way because of the curiosity of pussy pleasure, and now I finally got him to eat me. ……

The last thing I wanted was the pleasure of nipples v

You’ve got a body that can’t be satisfied without the pleasure of nipples.

No, it’s not.
You’ve recreated yourself.

I’ve done something to myself that I can’t take back.
You have to be aware of that.

If you want something done, ask for it, right?
[Pussy is not enough. Let me torment your nipples.] That’s it.
Yes, please?
