By the way, this is an interesting idea, to put a moral choice in front of wife, to avoid problems for yourself (there are already tense relations with husband) or to help the mother of the MC.
And the decisions made by the wife based on the choice of the MC, this is an ideal option.
The best option, as for me, would be if the author of the game slightly modified the scenario. One update to spend on this...
I was also thinking about that slightly rearranging the story would put more sense to the characters reasoning.
The wife should pick up the job at the refugee camp a while after the MC's promotion. It would be her way of trying to take away the MC's boss' leverage over the families only financial income, and no longer have to give in to having sex with Chris whenever he feels like to threaten her with firing the MC.
She had heard about the harassment complaint at the camp, but came to terms that she can deal with these better than with having to cheat on the MC.
That would be her reasoning why she is initially quite adamant about keeping the job.
To now fill the early stage's content gap the dev just have to add some suspiciously friendly neighbors.
I would have suggested a single mother with a 18yo black son (yes, she's secretly a sizequeen and has no idea who the father is and feels a lot more affection for her son than she should have), she tries the groom the wife into hooking up with her son because she can no longer keep up with his growing needs on her own and is now looking for someone she can trust to help her out (she "doesn't want to let the son hook up with girl at his high school since they would only exploit him for his cock and wouldn't give him the love her deserves" <- her reasoning for setting the wife up to become interested in having sex with her son)
But that would probably not go well with Patreon, since even without showing it implies that the mother also has sex with her son.
Other options would be a single mom living with her black lover, and the daughter stays at college.
Or a cuck husband and his wife. Could even start with the MC and his wife agreeing to a threesome with the female neighbor with her husband watching while taking pictures and videos, and develops into the wife gets invited over more often without the MC where she gets exposed more and more to the cuck-couple's black friends.
Also an interesting story would be: in the beginning when Samuil was acting friendly/innocent towards the wife he could point out that she looks somewhat "unsatisfied" (he would phase it more likely "underfucked") and offers her a herbal pill that would incease the MC's dick size and stamina.
Plot twist, it actually does what he promised, therefore the MC uses it a couple of times happily, only to find out that using it more often leads to ED and the MC no longer can get an erection without the pills.
With Samuil/the camp as their only source of supply they could make the wife do things in exchange for pills without the need for blackmailing her into actions by threatening her to tell the MC about her infidelity.
Another option for the player her would be:
The MC not wanting to admit defeat by having to give in to Samuil's demands stands strong with a limp dick.
The wife in need for sex and wanting to help her husband is asking a coworker for suggestions how to help the MC. She recommends the wife a doctor, her boyfriend had a similar issue and that doctor was able to help him in overcoming it.
I'd assume you can already guess what kind of route that might become since i made sure to to phase it "overcomming the issue" and not "curing" or "soving" it.
Yes, the female doctor would be somehow affiliated to the refugee camp and would most likely medicate the MC with testosterone blockers, estrogen pills and prostate massages to help him release some pent up stress.
At some point she will have to leave the city for a while but gave the MC her phone number in case he needs advise, and will send him now and then some "tutorial" videos how he could get release on his own while she's away and not able to help him herself.
Fast forward, Chris fires the MC because he is no longer able to hide his feminine development and starts to distract his employees with some flirty approaches and no longer fits the job of the manager.
Wife finds MC a new job as supply manager in a storehouse, an easy desk job that doesn't require physical work, and also offers some days of homeoffice. Gets promoted to customer manager a while after, just to find out that the storehouse is the main supply for the refugee camp and he has to visit the camp regularly...
...since i've created quite a wall of text here again i'll take break for now. Maybe the dev might find something inspiring in here for current or future content.
