fucking my step-brothers bully in front of him

*bullys pov* the step-sister opens her door, "who are you? are you one of my step-brothers friends?" you ask to come into her room to tell her that youre not his friend, youre her step-brothers bully. since the step-sister is already a bitch to her step-brother, she isnt phased. but she does have something in mind. she goes to get her step-brother and makes him watch his own step-sister fuck his bully. youre going to have to show me if you are worthy of actually being a bully.
