"Uncle, are you really that interested in my slit?" When his bratty niece Hikaru points out that he was Hikaru at her, the uncle shows her his slit and ejaculates while rubbing his penis against her. Since then, the uncle has become addicted to her sweet and sour scent and licks her slit from morning until after she urinates. "You smell like piss! "You're so gross," she says, but she licks him all over, and then says, "I'll stroke you in my favorite slit," and they have a passionate sex session using her immature body. Although she calls him a "bastard uncle,"Hikaru comes to depend on him and desire him. The two of them live out their days without a place to go, and they fill each other's void with their fleeting, sweet and sadistic life.
