Quite alright. I rather prefer something that was obviously made by one person than a bunch of bought assets.
I did find your caricature's comment about consent a bit weird. Many NSFW games like this don't bring it up because they know they are morally wrong. But when you do bring it up and tell the main character that you need permission from the partner before the app works, but then literally don't do that and it works anyway, you portray a very flawed form of consent.
Currently, the way you are writing it, she gives consent because she is a pervert. But that is not how consent works.
I am sure you didn't do this on purpose. If I were you, I would reword this part.
Edit: Also, make it so the space bar can be used to forward text aswell.
