So maybe 3 Endings, each respectively where the Wife is blackmailed to sex, consents to cheating, or becomes the dominate. Pregnancy is set in stone by this point, so that stays. Have the final choice by the player be to A) Reveal whos the Father, where we have the usual 'Husband walks in on his wife cheating' scene, but have variations depending on which route the wife is on (Shocked and guilty on Blackmail, a bit sad but resolute on Consent, total admission of cheating on Dom) and see where that goes. Option B) Cover up the pregnancy by making the husband thinks its his for the rest of his life, and minor changes depending on route. On Blackmail, Husband's business is booming, becomes successful, hires Futa full time, behind closed door sex continues. Futa taunts Wife, and Wife accepts her life. On Consent, same as Blackmail, but generally more happy vibes throughout, add in cheesy line where wife 'considers growing the family', winks at Futa, husband is oblivious. And on Blackmail, husband becomes depressed, Wife and Futa take over, become rich, Babies abound.
This may be too much, and I'm not demanding these, but after finding a pretty entertaining Futa story after a drought, I just want this game to keep doing well.
...The 3 energy drinks and a coffee also helped.
