Field leveling is a reminder of the reality the house always wins, spoiling that fantasy with consequences.
I've been an active supporter of "twists" or even "leveling" in JAV for years.
As you stated, the overwhelming plots of JAV is cheating and NO consequences.
I will admit most of those "leveling or consequences" in JAV are hardly worthy but that's
probably a personal thing.
For me, it can be the husband/wife/boyfriend/girlfriend etc finding out about the cheating and kicking person out at the end. Or some type sexy revenge
More twists are needed.
Like for example, the titles where husband leaves, the
mom and son are having sex.
Why not have the husband come back, unexpectedly, and be piss off?
Or JAV, where mom and son have sex while husband is a few kilometers away.
Mom and son is finish and exhausted. We think it's the end, and suddenly...
dad get up and walks into the room.
Mom/son knows they can't get dress fast enough and looks guilty as fuc*k
Not sure why the directors leave the scenes so open at the end?
Maybe the main audience is invested the cheating more than anything?
