>It's another "Haha, Retardina-chan! I've got blackmail on you, now become my sex slave!" They don't so much as "write" NTR as they do just draw different designs and sex positions with the same fucking story.
@Snotnose9001 well, NTR doujins with good & refreshing plots are rare, same as vanilla story nowadays. Even though there are many things in real life that can be used as story material, most authors still prefer to use the boring recycled stories. Cuz they can save a lot of time for making it and those repetitive plot still sell well in the market.
