【Fantasy Art Club】Kuroneko Choco Ice

This is a 33-page work. (4 pages including the cover, 29 pages of comics)

My brother came home after cancelling an appointment with a friend.
I’m taking an ice cream to my room that my sister asked for while I’m drinking alone.
There was my sister, shiny and black from the neck down, masturbating.

The broken relationship between brother and sister
She thought she couldn’t go back, but she and her drunken brother seemed to have blown it.

Crossing the line. The sister confides in her brother about her sexuality.

The drunken brother becomes increasingly uncontrollable.
