>>1869From the description, I was expecting a guy, driven to the edge by his sister's hate towards him, going "fml, I might as well have a piece of that ass at least." But no, he's actually a crazy siscon. Upon seeing her sleeping, he decides to tie her up one day. "Do you love me? No? Time to pound your anus until you can't live without me." Craziness aside, I can dig his anal incest fetish.
Blackmail ensues. The saving grace is that she doesn't listen and tells her sempai about it. Too bad she got caught. Decided to punish her. It's her third time getting it in the butt, and now she's already starting to orgasm. In public no less. Imma stick to my kawaii imouto, but I wonder if sempai would be a tougher fight…
