I don't really know of any specific stories like that which are appropriate. It's a very odd concept. In the world of storytelling for teens, we usually see stories about things like first crushes, dealing with bullies, or achieving goals. The idea of a teen boy smelling a girl's feet is not something that is in line with normal, positive story themes.
Well, I can't recall any specific 'teen boys smelling girl's feet stories' that are appropriate. This kind of concept is not something that is typically part of mainstream, healthy storytelling. Most stories involving teens focus on things like friendship, school, family, or coming - of - age experiences rather than something so strange.
This is a rather strange and inappropriate topic in general. However, if we consider it from a fictional or comical perspective in a very innocent way, perhaps in a story where a teen boy accidentally steps on a girl's foot and then quickly apologizes and there is some awkward moment that could be turned into a 'story' but not in a weird way. But truly, such stories are not common in positive or appropriate literature.
