Put It All the Way In! 4

"When I first started, I was very nervous... but now, strangely enough, now I'm not worried at all, I'm rather excited..."

One day, Satoru Ono happened to join the "Escape" project.
Satoru happened to overhear his classmates talking about a plan to lock themselves up in an abandoned factory, and then, Satoru was forced to join in.

Including Satoru, there were six members, boys and girls.
Eri Nakajo, the kind and outgoing class president; Mio Hashida, the quiet girl; Satoko Horiguchi, the mood-maker of his class; Genji Yasui, an all-round athlete; and Tadashi Hibiya, who loves to eat.

When they arrive at the abandoned factory, the first thing they do is explore... and then they see a shadow on the floor!
Surprisingly, the abandoned factory had a visitor ahead of them. There, a woman was sleeping on the floor in just her underwear!
Taking advantage of the fact that she was sleeping, Genji tried to touch her tits...

"The way you are rubbing my boobs is a little too rough!"

Unexpectedly they woke her up, but surprisingly she was kind and taught them a lot of things.
Her name is Chika Nishimura. She says she lives here too.
She says her reasons are similar to those of Satoru...
Now Chika joins the team and they start living together in an abandoned factory!

What happens when a child and an adult who can't fully grow up get together?
With a laid-back feel, they enjoy the freedom and began to have sex as their hearts desire.

"Don't worry, Satoru, stay as you are, I'll give you all the help you need! Ahh...! See? You're inside me!"
