Sissor Fight

N. When two females spread their legs in a sissor motion so that their vaginas touch eachothers. They proceed to bump and grind, while looking like sissors cutting at eachother.

My pussy is so sore from that intense sissor fight last night!

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.

“My favorite ships are siscon ships”
