my step dad is weird pt 2

okay so i told my mom about the whole leg thing and how it made me uncomfortable & so she told him not to do it. so this morning after mom left i was sitting on the couch and he comes up and sits by me. then he leans over and pokes at my toes and asks if it made me "uncomfortable" and then i say no bc as it happens i didn't think anything of it. then he goes on to talk ab my toenail polish and whatever. but now that i'm thinking about it his comment was very strange and almost smart ass like. i don't know what to do. my boyfriend thinks i should tell my mom again but it's hard to talk about it to her. when i did the first time she got mad at me for even thinking anything of it. i don't know what to do.
