You know that your stepmom, Sophie, understands how to dress appropriately because she does so anytime she goes out or when your dad is around. That doesn't seem to matter when you are home alone with her. Whenever it's just the two of you she refuses to wear a bra or any sort of undershirt. It may not be a big deal for some women, but Sophie has massive breasts that she frequently shows off with very low-cut tops. You know you shouldn't stare, but you just can't help it. You are mortified whenever she catches you looking, but she seems to enjoy your attention.
