A fanfic about lonely principals who try to seduce an unruly student. The story is written from the point of view of a student who is caught illegally at school and has to serve detention.
In addition to this fanfic, a comic was also created, presenting this story from the viewer's point of view. This comic is called Eternal Christmas Youth by Dieart77 (comic is still in progress).
Disclaimer: All characters are above 18. The story is written from the point of view of a student who thinks the principals are too old to be attractive to him and thinks there is too much of an age gap between them. As a result, there may be elements in the story that suggest age (elder or younger, for example). In addition, the author of this fanfic isn't English-speaking, so there may be language errors.
