Hmm, ... from the dialogue at the end (no spoilers), it seems that this is one of those school clubs that could probably never exist in real life (unless it went under a more innocent-sounding name than what's in the story's title, and conceals its true purpose from the average person). And while we can infer for now that Hareshiro's particularly into (figuratively) gobbling up male virgins, it might be IN-teresting to see what kinks her fellow club members are into.
For the answer to that, Tune In Next Time ... same H-site, same H-story.
