Thanks for your comments! Nozomi's route is the one I'm least happy with because the game's expanded so much since it was written and it doesn't really do what it needs to anymore. So, there's a major rewrite in the works and the "Kyou nearly kills his dream girl because he let his curiosity get the better of him" scene might not even survive. I know you're not the only reader who had a problem with it. But anyway, although there won't be anything too explicit (Penlight kinda set out its stall as being not that type of game) I'm expecting to add a lot more to Kyou and Nozomi's story as they explore their needs amidst the growing realization of the penlight's true abilities~
Working sexual tension into the other girl's routes is more difficult (the interplay with Sayori's alter may be as good as it gets), but it might come up in one of the many variations of both of their routes. I still have a lot to do before this game is finished!
