Zarathustra's manga / #Incest(2)

Honestly, a lot of stories come with a warning that 'homosexual scenes' are on it and may be offensive ... what is kind of a stupid warning for BL/yaoi stories. However rape, incest, pedophilia never are tagged or warned. If the kink in the plot is outside of convention, shouldn't be a big deal to warn, right? Clearly incest is not mainstream cup of tea.

This manga has no actual plot, just a bunch of kink fantasy shit (rape, incest, whatever) for the sake of porn...
