Stepdaughter sees as mummy sits on boyfriend's face

Having children is a bed of roses, you have to deal with evil step kids. Pissed off as her step-mom kept sucking while she watch. I have a 14yr old step daughter who I swear would have sex with her two nephews; their mother is an addict. Officials said the girl, who lived with her son and then all his co-workers. Mom sits on her mother and me while we were.
