Could be bot. Y'see, if not set after some time, the bot will assign original on parody tag. Given Ran doujin is pretty rare, the tag might not available yet. Thus, bot get incorrectly assume this is an original. BTW, Sango-Jin relationship is already hot in the original manga. Scalding hot!
Im really concerned about the fact that there is a more important issue than the nice sweet sex protrayed here.
A magical ability to hide while fucking? sure been seen already, but i will also be turned on if a loli sister like that enter the room in that moment.
What a surprise to see someone made a djs about Ran Haiiro. Although, after seeing someone made one for Jarinko Chie, nothing really surprise me anymore. Bloody Japaneses and their horniness.
Hmm, unlike the source material, Igumox's Jin is not as aloof nor intense. Sango is also not as demure. I think their interaction in original manga is still hotter than this one.
