I couldn't find the "seeking" topic so i just did "off topic," sorry. Anyway, does anyone know of any adult games where the protagonist gets more and more sexually sensitive? Like where they cum from the slightest touch or whatever?
This would go against the "stable sexual genius" with the "stable horse penis" trope. So, there's probably no "normal/vanilla" game with such MC.
And then there are the ones with a submissive male MC (main character/protagonist). In case you're after/don't mind those, then I think you can find some games where the MC gets "frustrated" from being "teased and not released" that somewhat fits the description of cumming from the slightest touch -- that too is a trope in the submissive circles.
You can search "denial" in the excellent thread Femdom Finder and check the games that have that tag.
