So far, the only scene to feature that is with Cynthia, so I could easily do that, too. Voyeur is going to be toned down as the game progresses, it's really developed into something else since uploading it here.
The truth is that I'm not interested in voyeur scenes (and even less so in those that include sex). As I've said before, if those sex scenes include a LI (present or future), I'd like to be able to prevent them from happening. If voyeur sex scenes don't include any LI, then I'm fine with not watching them. I don't consider watching voyeur sex scenes to be an appealing option under any circumstances.
