Excite engine - A Game Where the Hero Does Deep S&M with Unimportant NPCs

A game where brainless NPCs who'd usually say standard RPG fare like "Please hero, save this world!" get ravaged with S&M tools.

An RPG game where you don't do much adventuring,
but instead linger in the starting town doing unspeakable things to the female NPCs.
Use your S&M tools to have your way with the women,
and collect ecchi items to boost your power.
Finally, if you'd like, you can of course go on that adventure to defeat the Dark Lord and save the princess.
