Little bro x Older Bro
Where do I even begin with this one.It's like a vicious spiral of psychological twists! While reading this one you'll often find yourself wondering,"Which brother is more f-cked up?" The one with the huge ego & massive inferiority complex? Or the one with the biggest brother complex & dependence?
Incest, Manipulation, Self-mutilation, Insanely twisted mentality.
