Too early for a rating, so I'll leave some thoughts here instead.
I've only played a couple of this specific type of game because I steer clear of the AI ones, so the options are still actually limited. This one starts out quite well, and I like that you get to see the FMC's side of it as well as the MMC's. This greatly increases the options in terms of showing what's going on (although I guess some will prefer not to see too much and have most of the NTR hidden).
I like the setup, and I recommend people play it for themselves rather than just taking the word of the guy saying the FMC has turned into a slut after three photos. That's not the case at all, we don't know what happened at the photoshoot because on both the NTS and NTR route, it ends in a cliffhanger with the FMC telling her friend (NTR route) or husband (NTS route) that something happened and she's either ashamed (NTS) or "you won't believe what happened!" (NTR). On both paths, that could be a lot of things, it doesn't automatically mean that she ended up having sex, and I wouldn't expect it to mean that (especially with the dev's response that has already been provided on this).
Anyway, I think there's good potential here and I'll look forward to seeing how it develops. I'll note that the NTR path could be tricky in terms of content, because there are limited options there - unless the photographer takes photos/films them fucking and shares the results in messages with FMC, or FMC shares these with her friend. There may be other less obvious options that I'm missing as well.
Dev: I didn't track where it was, sorry, but I think it was towards the end of the NTS route where I caught a section between Grace and Logan where the messages were all in blue, showing from the same person. I also noticed that on loading, I was put at the first message and not the last, so I had to scroll down a lot to get up to date. And finally, if it can be worked, a "back" option might be a good idea. I accidentally clicked too fast and chose an option before I'd even read what the options were (finger slipped!) and I had to reload in order to get back to the choice, instead of just going back and playing the choice again.
Thanks for the interesting start, and good luck!
