Porn from ace trio reprinted (7)
I believe the answer is:
erotica
'porn' is the definition.
(I've seen this before)
'ace trio reprinted' is the wordplay.
'reprinted' indicates an anagram.
'ace'+'trio'='acetrio'
'acetrio' is an anagram of 'EROTICA'.
'from' is the link.
(Other definitions for erotica that I've seen before include "Objects designed to arouse sexual desire" , "Salacious" , "(Items of) titillating art" , "Sexual writings and pictures" , "Arousing literature or art" .)
