With regard to CCTV: Excellent game! The only complaint I have is that more content would be nice, but there was honestly lots in there, so I think you have a real winner with that genre/style.
The following is of course a suggestion for another type of game:
A while in the comments in one of your games I proposed an idea for "Tiger Mom". A brief summary: the premise is that the female protagonist is a stereotypical "Tiger Mom" (a very domineering, task-heavy mother who wants her children to succeed in everything and likes to be involved to the smallest detail). She can choose from a variety of ways to corrupt herself to help her son with various school-related goals (grades, dealing with bullies, getting onto sports teams, building up courage to ask a girl to the school dance, etc.). The main path is her offering direct "encouragement" or "rewards" to her son (or perhaps "punishments") for achieving the various high marks of a successful student. (optional) NTR path would involve seducing key characters (or their sons) to make life easier for her son without his knowledge (Eg. his bully, or his teacher/his teacher's son, or his coach/coach's son, or the boyfriend of the girl her son fancies). Another path is encouraging his older sister to help him out with some of his goals (maybe physical training to make the track team, etc.).
You've basically already touched on that concept slightly in CCTV (sister and mother helping with grades), and I feel you did it very well, but you still had lots of opportunity to really flesh it out if you went all in on that concept alone. (lots of opportunities for content, can scale up or down as work allows).
