SDMF-018 The brother is jealous of his sister's lover.

My little sister, Kanon Amane, finally got a boyfriend. One day, I walked into the room while she was about to have sex with her boyfriend. I interrupted them and chased her boyfriend out. I then decided to take my place and fuck my little sister. Mainly to satisfy my strange feelings of jealousy and rage.
