Count Down Akira (1997)

Akira is beautiful-so much so that he can have any girl...or guy that he lays eyes on. Unfortunately, the only woman he has ever wanted is the one woman he could never have-his own sister. When he first met Kaname-innocent to the ways of the world-his own world slowly began to change. The realization of the reality that his sister can never be his and that he can never find true comfort in her arms devastates him. There, from the depths of his despair, he finds salvation in Kaname's loving embrace.
