Making Sure No One Fucks My Stepdaughters Without Seeing the Guy Hiding in His Room

I went into my stepdaughters' room to forbid them to go partying; I'm not going to let any asshole take them. I stayed for a long time giving them orders, making sure they stayed still, but I didn't realize that they already had a bastard behind the curtain. The guy was there with his cock out, waiting for me to leave so he could start fucking them in my own face.
