Isekai Tragic Love

When he woke up, it was a flesh-colored world.
No, it's not.

Kazara Itsuki was surrounded by naked women.
The owner of the fruit, which has grown fluffy, says with a violent shaking of self-assertion.

"A hero from a different world who appears from the mirror of guidance. Please help us." Some of the naked women were long-eared, horned, tailed, and so on.
The view overlooking the land is clearly different from that of modern times.
And above all, they clearly said... this is a "different world."

When asked to help save the world, Ki decided to cooperate with them to return to the present age.
The hero awakens to a special power called "skill".
It is an ability that allows you to easily learn "swordsmanship" and "magic" as if you were playing a video game.
Using that power, Ki was active in a different world and made a name for himself.

However, on the other hand... the unique skill "NTR (cuckold)" has made women in different worlds who have become close to each other unknowingly cuckold one after another.

You cannot return to the present age until you save the world.
My new life was about to begin...
