siscon

A siscon is someone who enjoys fictional (typically anime) depictions of incest involving sisters. Can be sister x brother or sister x sister but not brother x brother (that would be brocon)

The word siscon can also be used to describe a fictional character who is in love with or very obsessed with their sister.
