【IronSugar ‘Iron Sugar】How my naughty sister became my sex friend

One day during summer vacation.
As she was relaxing in the living room, her sister (Mirai) noticed her brother’s brand new tablet.

[Did you get a new tablet?]
[I like it – can I touch it?]

When I reluctantly handed over my tablet, the future took the liberty of putting games on it and trying to personalize it.
The brother, upset by this, puts his hand into his sister’s chest.

[Give it back in 10 seconds or I’ll touch your chest?]

But the sister provokes him back.

[Okay? If you can do it, do it.]

My brother couldn’t back down from those words.

When I touched my sister’s breasts at will, what I found there were unexpectedly large breasts.

“Wow, that’s amazing! What’s with the volume?

[You actually have big tits, don’t you?]

The first time my brother touched a girl’s breast, he squirmed like crazy.
The way he looked at her made it morosely obvious that he had no experience with women.

Mirai, who was disgusted by her brother’s naivety, made this suggestion to help him get used to girls.

“Hey, big brother, have you ever seen a pair of tits in the flesh? Do you want me to show you?

This is the first time I’ve ever seen a girl’s tits in the flesh.

This is the first time I’ve ever seen such a thing.
