I am looking for stories, videos or Manhas where the mother/sister/both make the son/brother watch while his bully fucks them brutally. Preferably even after the bully cums inside them, they make the wimp eat the cum out of their ass/pussy.

They humiliate him, breaking all family bonds, maybe spit on him, beat him, verbally abuse him, cut his penis with scissors or wear high heels and stomp his balls making him infertile.

Looking for stories with similar plot in case of husband-wife or girlfriend-boyfriend scenarios but the sadism should be there.
