I understand your frustration. Unfortunately, you can only skip the scene, but the game could refer to those encounters in the future because they are part of the storyline.

I understand that it might be difficult, but please keep in mind that only the Rin sex scenes involving characters other than Rex will be optional based on the NTR preference and occasionally on the player's decision. However, for the other female characters, there will be very rare instances where you can decide whether they have a sex scene or not.

Creating additional options for each lady, such as replacing them with someone else, to make sex scenes requires a significant amount of work. This process involves creating all the drawings, animations, and dialogue from scratch, which can take months to complete because it is a one-person effort.

That isn't an option for me, and it's not very effective because:

1. Even like that, there are always some players that don't like any girl to have sex if she is not having sex with Rex.
2. If I implement this change, players will expect similar options to be available for all other scenes involving the ladies rather than just this scene.
3. I prefer to spend my time creating an entirely new scene with a different story and characters, rather than just making minor changes to the existing scene but changes that often need a lot of time to be ready.

I needed three months to complete this version. If I had chosen to add an extra way to play this scene, the release would have taken between 1.5 and 2.5 extra months, which is almost the same amount of time it takes me to create another sex scene with different and more original content.

So, to avoid problems, I prefer to kindly let all players know that this is not that type of game. This game is the type of game where, excluding Rin (if you have the NTR preference turned OFF),  all NPC can have sex with anyone other than Rex.
