My sister and I have the same mother, but my sister's biological father is our mother's brother, so is my sister just a half-sister, or something like 2/3 or 3/4 or some other fraction of a sister?

call her your half sister and never ever speak of it again

God I want to fuck my sister

Only have sex with her if she's older.

Ask the OP’s mom
