There are three routes in game according to the written text, make the marriage work, consensual sharing, and cuck.
Only issue is the games media is 99% your wife getting blacked, if you choose any other option you get the same few dozen fairly boring images each night in an otherwise totally lifeless click dozens of times to move around your house and waste time routine.
Also if you don't spam the back button to hope for RNG, your wife will leave you, its NOT down to your choices, you can't choose to initiate sex that actually satisfies her, if you try seduce her you get a quicky that doesn't fill that requirement and you loose 10 of her "satisfaction" points and 3 happyness. Instead you need to try spam entering the bathroom when she showers or talking/massaging in the bedroom in vain hope she initiates the actual sex minigame, and when you complete it (in theory shee needs to have an orgasm to "win", but normally she will come like 20 times while you wait for your bar to fill) she will rewardingly not loose points! Thats right, you don't actually get her to increase stats, she just doesn't hate you less. The same applies to what your wife does during the day, if she has encounters that progress certain NTR routes is complete luck, so your either going to spam the back button to get those scenes or avoid them.
So right at the moment (and with no indication on what content is added in future) play this game or don't depending on if BBC is your kink and just ignore the other tags, they exist only as a bare skeleton for conveying the other more effectively.
