Awesome first release, this game is very promising. I'm a sucker for Sisters/Childhood friends (as long as they're virgins) and Sephora definitely scratches that itch. From what little I've seen of her, I have very high hopes. The other characters are fun too: Lianna, Jessica, and Kiara all seem nice. I'm excited to see the agent, as well as the redhead and the Asian girl from the title screen.
I don't know if you're a native speaker or not, but it's always nice to see games that don't devolve into Engrish.
Honestly, the biggest surprise and what I see as one of the most promising things in the game is actually Montez. While the Black best friend trope is more than a little tired, it fits this setting well and most importantly, Montez is actually well written and likable. So many games have male friend characters who feel completely tacked on, as if they were only added to check off a box, even in some otherwise well written games. When a game actually incorporates a well written male friend character it more often than not correlates with said game being well written.
Keep up the great work, I can't wait for what's next.
Also, just some advice: be careful with Patreon, since you have Incest in the game. That could become an issue in the future, although some devs manage to get away with it. I would recommend also making a Subscribe Star account as well.
