John is Janice's husband.. there is no cucking there at all. NONE. The reason is because they're married and they should do what married people do! But if you played the intro, you'd learn they haven't been that active.
I haven't even downloaded the 22 version because I wait until the final version drops. The only way I suspect you could compete with John is if he tries to seduce Julia. Think for a second.. you're already having sex with John's wife so I wouldn't blame John for suspecting it and trying for a play on Julia or even Kelly to get back at the MC. IMHO, this would a fun scenario.. you would have to keep them at arm's length from John while trying to break him mentally so he'll flip out, divorce Janice, and leave. Finally! A challenge!
Guys.. it's not "cucking", it's called "manning up and rising to the challenge"! Are you man enough?
P.S. - you all owe me if my scenario happens in the game.
