Poor younger brother watching stepsister have sex with best friend

The poor younger brother watched his stepsister have sex with his best friend: This boy invited his best friend home to play, not understanding what the other boy's taste was, but he always liked his best friend's sister named Nao Jinguji. Nao Jinguji didn't care much about these boys, until the other boy came forward and seduced his brother. Nao Jinguji seemed carefree at first, but the other boy didn't give his brother a chance to answer, and just fucked him brutally. The younger brother saw it and could only cry and look at that scene. Will the two of them get together when the age difference is quite large, invite gay brothers to watch!!
