There really is a lack of more imaginative story settings for this sexual fantasy. There should be high fantasy elves and barbarian kingdoms or stories of immortal goddesses who fulfill prophecy of having sex with their demi-god sons, cool superhero stories or sci-fi space operas.
Many of the tales in the MS genre that I see are copy-paste same-old same-old tropes. If anyone has any more unique stories please share more:
This one is a great one about a King Arthur style prince who marries a princess who he isnt in love with, his evil sorceress mother uses her magic to transform into his new bride and… well you should read it and enjoy it yourself:
