Synopsis
Summer Vacation
You are on a long vacation, visiting your relatives’ house, which has become an annual tradition.

The twins, who call you brother and love you, love you so much that they begin to engage in extreme skinship.

1Let’s take a nap together, big brother
The twins, tired from waiting for you, are taking a nap on the porch.
When the twins wake up and notice your presence, they invite you to sleep with them.
But as you sleep with them, you start to feel naughty.
(6 minutes 20 seconds)

2When your face is this close to mine, it makes me nervous.
I’m starting to get excited just thinking about what we’re going to do together.

“Don’t worry, you don’t have to hide it. We’ll be by your side, and we feel the same way.

The twins, who are very curious about naughty things, are teasing you, their favorite brother, while you are teasing them.
The twins, who are very interested in naughty things, start playing naughty games without telling their parents.
(16 min 32 sec)

3. I’m going to nuzzle your dick and make you gurgle.

“Hey, kiddo, do you want me to give you a new one called “Fura-Chio"?

[What’s “fluo"? What’s a frenchie?]
[What is “fluffy-o"?] [
The twins begin to suck cock for the first time, relying on what little knowledge they have.
The twins, who lick their pecker playfully, mistakenly think it’s good manners to gobble it up.
(11 minutes, 56 seconds)

4The last thing you want to do is have sex.
I know… In times like this, the last thing you want to do is have sex.
[What do you do for sex?]
[I put my dick in your pussy and pump it in and out].
After a round of foreplay, the twins start demanding sex at the end.
You can’t help but be drawn to the soft, lush skin of the twins.
You can’t take it anymore.
(15:07)

5Please teach me how to have sex to make babies too
[big brother, you’ll do it to me next, won’t you?]
[Maho had a covetous look on her face the whole time I was having sex with her.]
[Because I want to have sex with my brother, too].
You’ve just been carried away by your twin sister, Natsuho.

You can’t refuse your sister Maho’s request, so you start the act again.
(12 minutes 58 seconds)

6Let’s make a baby without telling our mothers.
If you’re exhausted from playing with your nieces and nephews…
You fall asleep while listening to the sound of insects playing all alone.
But you can’t forget the sex, and the twins crawl under the covers.
(14 minutes, 26 seconds)

Total play time, 77 minutes, 19 seconds
