supermario:
I think my all time favourite story is a toss up between "the Spank Shop" by Seegee and the Troy story by Rollin
I especially enjoyed the F/M chapters of the "Spank Shop" series, but also the ones wherein Kimberly got her bare buns blistered by Aunty Andrea--and likewise Aunt Carla's parallel letter-style short series about Amelia (Kimberly's counterpart in her stories) getting her bare seat smacked.
It's too bad that Julnick (Julie) won't allow her work to be posted in the Library (although I'm not 'second-guessing' her decision, I'm certain she has her valid reasons), she wrote some terrific stories about a dozen years ago--my all-time favorite of hers was "Into the Woods" and it's in my Top Twenty overall.
No, I haven't really worked out all of my Top Twenty, perhaps someday I will, but I certainly have some clearcut candidates in mind... --C.K.
