JO Instructions - #4 is a roughly 6100 word erotica taboo short.
In J.O.I. you are the main actor. There is a 1100 word (plus or minus) setup (A.K.A. setting the mood music) followed by the person doing the catching, telling you what to do. There is essentially no physical sexual contact between the instructor and the instructee.
