Hey, incredibly sorry for the late response, I don't go on Itch.IO that often and kinda ignored the email cause was at work.
The only one in my experience that tries and succeeds in doing story + intimacy as well as the Fixer is Third Crisis, kinda of TBS (turn based strategy) less than a visual novel esque game. And is less story focused RN, more into world-building but the quality is there. There's also the Star Channel 34 by akabur, that has a really nice plot-line for a sex simulation game. I'm always interested if there are any similar games that are NSFW, so if you have any, i'd love to hear it.
