Excellent. You get every pairing you want at least once, and there is usually little enough plot to skip whatever doesn't suit you sexual preference. Generally good choice of words, but I tended to ignore most of the descriptions of places- they didn't seem to have much bearing on the story. I award a kudos for actually using the words involved (even 'prostate') without being a turn-off. 16 chapters means plenty of material. I was slightly disappointed that the author was so hesitant with the Ron/Ginny pairing- I feel that if you're already writing 'underage bisexual incest orgy' then it doesn't make much difference if they never Technically have sex.
