You are not being cucked, I will call it "being NTR'ed". Come back when you understand the difference my young padawanUnfortunately, I don't like being cucked as the main focus, it ain't my fetish. If it was the MC doing the corrupting and cucking with occasional NTR moments I'd be fine. But by the sounds of it, this game ain't for me, which sucks because I love how the artwork looks in the screen shots.
Best of luck in the project
