You're talking about the cam girl and the client watching each other masturbate I'm guessing. I presume all the game has to do is avoid showing the client? Even if they do, she's not having sex with the client, so the only cucking will be in the players' head if that's not something they want ... in which case this probably isn't going to be the game for them.
On the other hand, the player may not see any of that regardless. They haven't so far -- all her online interactions have been from the MC's POV, and as portrayed, those type of actions would be in private rooms, not public for all to see.
Now, if you're talking about the cam girl bringing in someone to have sex with on camera, if that happens I think we know who that's going to be.
Not to mention the cliffhanger, which could completely change the dynamic going forward.
