The act of having sex with your clone. It is the combination of incest, masturbation, and homosexuality. Can potentially and technically, mean twincest as well, if identical twins are involved.
You are the clone of your original and you find yourself naturally attracted to him/her. So you have sex. The homoincesturbation was excellent.
