Nobody can take care of a guy like his stepmommy, and if his girlfriend thinks she is up to the task, she's going to have to prove it. Whatever he wants, he can get at home, so what is the new girl bringing to the table? She doesn't have the experience that his stepmom has, and that innocent face, untouched body, and tight pussy can only take her so far. However, if she's willing to share him, things might be different. Nobody would say no to a threesome under this roof, especially if the girlfriend is willing to take notes, learn, and put his tongue on more than just her boyfriend's dick.
