I really don't get these sort of 'corruption' games (i'd argue games like this are more about control than corruption).
Take the banana blowjob masturbation scene for instance. If you choose to have Anna think about Chris, a big part of what makes it hot for her (and the reader!) is that she has a loving husband and she shouldn't be doing that. It's naughty and slutty. She's being a bad girl, and that's great.
But then the whole rest of the game is about making Anna and David hate each other and sabotaging their marriage! Every bit of successfulness in that regard makes events like the banana scene less wrong, less naughty, less slutty. Of course people in a broken relationship will be looking elsewhere. That's normal, not 'wrong' or corrupt.
These things actively work against each other.
There's a lot to like about this game, but the overdone multi-pronged conspiracy and contrived circumstances that it's predicated on, and that undermine the corruption aspect, kind of ruin it for me.
