Looking for SISTER-NTR, I will also recommend some, check it.

[RodrigoRGM]

any sister-ntr recomendation? it can be any media, VNs, doujins, RPGMaker, manhwas... It's so hard to find this specific type, especially since in japan they call childhood friends onee-san/chan too.

Bonus points if the scenario revolves around the sister getting a boyfriend.
