Now this is an unusual Hyouka work -- one that features the entire Classics Club except for Oreki. It's also not often you get to see Satoshi score with both Mayaka and Chitanda at the same time.
The subtitle "Why Didn't She Ask Oreki?" is also rather clever, as it ties in perfectly wth the plot (Chitanda asking Satoshi about fellatio instead of Oreki) and parodies the title of the second arc in the anime.
This is the kind of doujinshi I was hoping to find when I said in another comment that I wanted to see a Hyouka work with a more original plot. Thanks for sharing this!
