That... isn't what I think of when I think of denial. Maybe it's another meaning I'm not familiar with, but to me denial means being denied orgasm, either short term like Riley did early on, or long term like you have with the chastity. Being ignored completely, I guess that's a fetish but I can't think of what I'd call it. The earlier scene where MC was tied up and gagged was somewhat similar, but perhaps covered the frustration a bit better (not to mention having images). While on the topic of that scene, it could do with some work; the game tells you when you try to go there that you'd better have a gag, but Riley never told you to bring one. It's rather weird that you just know that she wants a gag. Also no gag shows up on the picture at the side.
One thing I would suggest, if you're going to introduce stranger fetishes like that, would be to have a settings screen where you can turn them on or off, like many other games have. That way people who don't share those fetishes don't have to go through those events to get to the ones they are interested in. Also putting several of them in a row so that it's the bulk of an update is probably not the best idea.
