It's a neat little game with potential. Being a fan of seeing swinging and sharing (NOT a fan of NTR or cuck) There are a couple of strange quirks that distract me from enjoying the game. The first is how fast the author goes from a loving couple to a couple who is ready to forget their vows. Sure, nobody wants to stick around forever to see a hot sex scene. But it does move very quickly. Although, it is highly customizable (choosing partners and kinks easily, skipping unwanted kinks).
The biggest roadblock for me is the wife's handling of Darrel. This scene says it all...
The above representation of text is not a logical or likely outcome of a strange man texting a happily married woman. I would expect the wife to be able to say yes to going to the gym without engaging in a cheating relationship with Darrel. The reader is forced to end a relationship with Darrel, or allow the wife to very quickly betray and cheat on the husband (she immediately begins texting and quickly gets inappropriate).
While I had no problems navigating the different paths where others have apparently struggled, the choices and optional comments are not always obvious or logical sequences that would determine a change in path.
In the future, I hope the author is able to sort out this issue and make it possible for Darrel to join the couple without the cheating overtones.
Edit: Just played through again for fun. The Love route with Ethan and Nat is awesome! The pregnancy talk and the support they give each other are really well written. THAT is how you write a loving, romantic, supportive relationship between husband and wife.
