This is actually one of the more-enjoyable RPG games I've played in a while. I've got huge kinks for ass/feet/armpit stuff and this game provides it all where most usually leave it on the sidelines, which is a refreshing thing to see when it's often neglected. Plus, there's also milf dating, which I'm always down for.
There is a little constructive criticism I would give, however. The first being, which I think has been mentioned previously, is the lack of actual images to go along with things in order to make the scenes a bit more meaty. Don't get me wrong, I do enjoy the scenes as they are, but it really needs that kind of visual oomph in order to truly appreciate them, I feel.
If you're struggling to find images for particular scenes, you could always try exhentai.org and search for keywords in their database. They've got THOUSANDS of hentai images taken from all sorts of games and you could always search for key words to help make tracking down certain things a bit easier. Heck, even typing "hentai armpit" into Google images got me a set of decent results.
The only other thing I'd say is that, despite declining Annabelle at the start in hopes to open new option pathways with different girls to experiment around with, my character always seems to flash back to Annabelle and his undying love for her and then denies potential candidates for my branching-out despite having rejected Annabelle earlier in the game. I don't know if this was intentional as to save on scene creation (which I completely understand) or just a mistake, but it can get somewhat disheartening when it happens repeatedly. I know you said it wasn't designed to be a harem, but it poses the question as to why you even get the option to deny Annabelle at the start if your character's just going to continuously think about her afterwards regardless and deny future girls, making your choice essentially meaningless.
But anyway, that's just my two cents on what you've created so far. I like the direction it's heading and the characters overall are very likable in my eyes, since I usually don't care much for characters or story in RPG vore games, but this one I actually found captivating for a change.
I look forward to any updates you may post in future
