Checked it real quick.
Description says trans, but with a dick (it's not as huge as seen in some futa games, but (depending on camera angle a bit) still seems above avg. lengthwise) and tits like that feels more like futa to me. (And that seems to be in line with how you state it yourself: "This game is completely unrealistic, completely parodic".)
I think you can reach a wider audience if the boyfriend is not a given / optional and/or if at start you could establish if MC is into men (femboys), women, other trans/futas or all/any of these, so the player/reader isn't necessarily confronted with these choices in-game — or, as per pref, let them choose on a per-situation basis (like it's currently, apart from the given situation with Leo).
Personally I'm not interested in getting it on with the femboys (e.g. had to ctrl the beginning). Ash & Ning I like in particular.
Pretty nice job on the UI (except I would tone down the quick menu a bit) and production value is above average.
Didn't read much of it, so won't/can't say anything about that.
Good luck!
Oh some minor things/suggestions:
- have showing the outcome of a choice (e.g. 'Explicit scene with...') optional per user pref - to me they felt kinda like spoilers;
- Menu: it's not clear enough in which section you currently are, especially relevant for Load-/Save Game screens (these look exactly the same). Adding headings may help?
