Every year the protagonist visits his grandfather living out in the country.
There's no one his age to play with there, so he wanders a nearby forest alone.

Deep in that forest, there's a place called Mayohiga.
There's a tiny shop, a shrine, and three mysterious girls.
They use old words and older mannerisms, and each time he visits, he plays with them.

It seems however, that this year there's something slightly off about them...

This is an erotic adventured-based RPG made in RPG Maker MV. A boy is toyed around with by three erotic lolibabas.
There's a little exploration to be done, but no battles. Erotic scenes are unlocked by talking with the lolibabas and finding certain items.
You can view any scene again by going to the lolibabas and begging them for more.

Each heroine's first scene can be enjoyed in the demo version.
