I’ll answer with a general message. Tyrone has a specific role in the story, and it is not connected to the main LIs, and Jessica is not one of them. Moreover, no more scenes of this kind involving him are planned. As for why a third option wasn’t added right away, it’s simply because it hasn’t been rendered or prepared yet. As I mentioned on my page before, the update has been delayed due to unfortunate circumstances, which resulted in part of the content being lost.
The problem with Tyrone is that the player now thinks he's sleeping with a Li's when he's alone with them, and it doesn't matter if it's off-screen. And what's the "special" role supposed to be, that he's sleeping with the MC's family or that he's cuckolding the MC?
And now here's the thing: you say you didn't have enough time. Instead of doing the scene with the black woman, you should have finished rendering the party scene first, with an alternate scene where Tyrone is thrown out of the room and the MC fucks the woman alone. Personally, I think you have no idea where you want to go with your game. You have no idea whether you're supposed to make a harem/sharing/swinger/NTR or whatever kind of game. So, forget about harem now; the dev has successfully ruined that.
You say that thing with Tyrone was a one-off, but why should we believe you? You've lied before and proven you can't be trusted. Besides, you already took a picture with the mother where she's holding two penises. Now, every time you're not with a Li's, you get the feeling Tyrone is fucking the off-screen girl. And I think Jessica was planned as a Li's, but now that everyone's getting upset about it, the dev just says, "Yeah, she wasn't planned as a Li's." What bullshit! If you were into MMF, you could have done it with any NPC woman, but not with Jessica. She's too good-looking not to be a Li's.
Dev, get to the bottom of this and try to decide what kind of game you want to make. You can't do everything at once, that just annoys the players. And start listening to the players; after all, it's the players who play the game, rate the game, and give you money if necessary.
