Nice renders and music, interesting setting.
Some (subjective) feedback on Ep-1 :
1. Better provide a default name for players who are lazy or do not want to enter a name without knowing the cultural context of the story.
2. The first images with the unusual POV angle can be unpleasant for some people because they can cause a seasickness effect.
3. If you say Good Morning at home you usually do not greet with a hand.
4. Ayame harassment pics : the front side pics show white panties, the backside one with the wedgie does not show white panties.
5. Ayame : "Also...Don't tell her about it, Miyuki. Please!" -> Probably mc name instead of Miyuki meant.
6. Unusual to greet stranger (Alice) when wearing just underwear = visible bra or panties. (Miyuki bra, Ayame panties)
If Alice is a close friend to the family : ok. But then she would not need to introduce to mc ...
7. Sara story rushes forward. Sara has a new job, just arrived and stays at mc's home, but she has already lots of business stories running (dancing, Emily, Yuri, ...)
8. Sara model has small lips, Sara bimbo in latex suit seems to have fuller lips. (visual illusion?)
9. Sara overwhelms mc with sexual rewards up front (grind/lap dance, show boobs, show ass, bj, show pussy, show Miyuki pic) ... it's overwhelming.
10. Thanks for mc with rather average dick size instead of monster cock.
11. The second bj by Sara produces way too much cum compared to the first one. Second or 3rd ejaculation (especially within minutes) usually has less, not more cum. If Sara is a professional and offers the bj to mc, the cum load should not be a problem for her.
12. Emily giving mc 500 $ up front seems a bit irrational. She doesn't know mc and Sara either doesn't know for sure if mc will support her or not.
13. Kerry is a stranger to mc. Kerry asking to see mc in her room where mc has to enter naked is a strange story.
14. Kerry wears a mask except for one image where the mask is missing.
15. After 3 ejaculations the mc should be pretty empty, so only a soft encounter with Kerry.
16. Kerry and mc meet for the first time ... she asks mc if he would leave everything behind and go away with her ... shouldn't she first get to know mc better?
No need to comment on my feedback in detail. It's subjective ... it's your story and your game.
Good Luck!
