What if I told you the route I'm talking about had nobody else involved and there was never a scene discussing humiliation, swinging, teasing other guys? We went to the beach the first night, drank danced, and went home and had sex in the bed. The M.C cooks breakfast I decided I wouldn't cheat on his wife since that's the path I was on. After that we had breakfast, then went back to the beach and swam around together, after which there's a choice between surfing or relaxing on the beach. M.C and his wife, and the surfer siblings go out into the water, at some point the m.c is left with the surfing sister, while the wife goes of screen to continue practicing with the surfing brother. The next thing that happened was the wife and the surfing brother disappeared. After looking around the m.c doesn't notice his wife who is clearly visible to the player blowing the surfer bro, however surfing sister noticed and distracted the m.c so he doesn't see anything the scene was actually kinda funny but was completely unexpected.
If you go the other route you'll end up sunbathing with your wife, but you'll fall asleep then some random guy shows up talks to the wife briefly and she disappears for what I assume is 40mins (based on her dialogue) returning to wake up the m.c. Up to this point there was absolutely no choices that asked the player anything about cucking, or sharing. The very next choice the bartender is about to tell the wife what kind of island it is and the choice to change the subject has no bearing on whether she'll blow the whole club or not. The other choice about cucking the m.c, or cucking his wife does nothing to change anything currently, and the option of swinging also does nothing currently, mainly because at this point she's either given surfer bro a blow job or ran off with the guy on the beach which is cool if you're into that, also nothing wrong with diversifying a playthrough of those are the choices you are presented with and chose.
I have no problems with any of the content outside of the cum swapping, and if you read my original post I wasn't complaining, I was asking for clarification on if the route was bugged(which is possible because apparently the dev is new which is also okay) or if this is the actual story of the game. I never once implied there was a problem with the game in itself that needed to place the blame on anyone but me, because there seemed like there was a vanilla option based on the choices I posted in my first post on page 14 I believe.
The only real critique I'd give at this point(other than the option to refuse kisses) is the game would make more sense as a kinetic novel at this point since apparently there something in the water that is forcing everyone to act on their darkest sexual desires it makes no sense that the m.c can somehow resist it. Even me posting that last paragraph, isn't me suggesting it should be done or even considered because I think more games should branch like this, because from playing vanilla and the harem route the character's are almost completely different. Ranging from borderline shy conservatives to sexually liberated progressives. So I agree it's probably my fault, however it could also infact be a bug and content is missing, which the dev can hopefully look into at some point or clarify.
