I don't like this woman for the mere fact that she's playing both sides/fields at the same time. Make up your mind woman. Either fuck him or leave him alone. But you can't, right? You've got the attention you crave from a young dick guy ... attention that you're NOT getting from your husband. But at the same time you're NOT crossing the line and just leading him on. I don't care if she cheats on the husband (or not) but at least make a decision to do it or not. And if you decide to stay faithful to your husband ... just leave this guy alone. I expect nothing but blue balls in the next (few) chapter(s) ... hot blue balls but blue none the less.
Edit: I also just realize that the husband doesn't even have a face. The author intentionally does that so we can feel less sympathy for him. I mean, the MC could potentially fuck a no-face (and no-name?) characters wife who has been neglected (apparently) ... that's a very specific kink huh.
