I don't know if you'll like it, but you can try my game :
Lolita gone wild
It's a free RPGgame.
The girl is an ingenue at the start of the game, but she clearly enjoy the things she discover...
just keep in mind that this is only the second release, so the game still needs to improve.
There are currently over sixty CGs available.
(the version was supposed to have 69, but I've been reported a bug that prevents the neighbors' CGs from being triggered. It will be fixed in the next update).
I'm currently working on the next update, and I plan to release it very soon, but that doesn't prevent you from downloading the current version, I always make sure the old savegames work.
Hope you'll enjoy the game
