Looks like it is pure NTR or NTS only. No other route, as MC is already getting hard and excited at the idea of other men with his wife (without any player choice). And it is only about 5 minutes long. The writing is pretty basic and just jumps right into getting the NTR all set up. No emotional build up to get you attached to these characters first to make the NTR actually matter, just right into it.
Typical wife's best friend corrupts her and gets you to admit you like it. It's pretty much the same story as Stay Online. Way too similar, not really unique in the slightest. Husband is away on a business trip and the wife's friend tries to get you to admit to being a cuck and corrupts your wife into cheating on you/cucking you. Not really that different at all.
Was hoping for something more unique instead of the same story as someone else's game. Either way, best of luck with this and thanks.
