clonecest 

When clones have sex with each other.

Julie trailed her fingers up Julie's arm and along her collarbone. Julie threw her head back and moaned. Then Julie looked right into Julie's blue green eyes, and stared hungrily at her clone. They locked lips, and fell to the floor, groping each other's perfect identical bodies. They were committing clonecest, and it was wonderful.

One of the nicest people you will have the privilege of having as a friend. Selfless, caring and you will never feel judged around them.
