He punishes her like a whore for being a whore she masturbates when she's alone

When this guy comes home to find his girlfriend masturbating like a prostitute, she gets very angry. Why is he touching her pussy without being present? He plays a good fight and tells him that he has to learn to respect him and that if he has a hot pussy, he has to wait for him to come back. He puts his cock in her mouth violently to subdue her and then he starts fucking her, giving her too strong in her pussy so she has no temptations to touch her alone and always wait for her ass.
