List of things that Laura does without permission from MC:
- all completely avoidable, don't play...

Both Mike and Oliver are completely avoidable.
Laura is acting with a bit of her own agency, based on MC's (your) choices. She's not cheating and she's not doing things without the MC's permission, unless you enable surprises. She's simply not seeking express/explicit permission for every single act...
I don't disagree that there are things I wish were implemented differently, but not my story. And the story clearly indicates MC is giving Laura agency/freedom to act, she's not just a sex puppet. Personally, my only 'complaint' is that I wish there was a way to make Nathan (and others) keep wearing condoms while MC is the only 'raw' participant, but again, not my story...
Hate to break it to folks, NTS is 'cuck' porn...

Generally, NTS is similar to NTR, but in NTS the MC knows, is ok with it, gets turned on by it, encourages it, and the wife/gf still loves/respects (to a degree) the MC, she's participating in the fantasy, and enjoying it... I would agree NTS isn't only 'cuck' porn, but it seems only us 'westerners' try to limit/differentiate NTS to fully 100% consensual express permission for every "sharing/swinging" act. However, that's not the case...
I understand this isn't your idea of NTS/sharing/cuckold, but it's very much netorase, just not with the level of control, constant consent, you'd prefer.
I have enjoyed the story balancing out the NTS a bit, making it more 'sharing', by adding Ashley's and Tara's interactions with the MC, and cuckquean

Laura.
Fingers crossed, I'm really, really hoping to see Laura hooking MC up with
Sarah (Mike's exGF) and Sophie/Sophia? (Nathan's new GF). And either Ashley, or Tara, or both, hooking up with Laura. That Ashley&Laura strapon tease was hot, and of course disappointing at the same time...lol
