I know someone else had a similar problem like this a while back and got some advice so I'm going to ask you guys what I should do about the situation... This first started about a couple of months ago starting at school. My step sister (who is 17) saw me (I'm also 17) in the hallway and told me that she would drive us home tonight instead of taking the bus. During the drive home I was listening to music when my sister tapped on my shoulder to get my attention, she started asking when I was going to get girlfriend or that I should hang out with my friends more. I just simply ignored her half the time untill she slowly changed the tone of her voice in a very subductive way and said that she would "help me and teach me." At this point she was looking at the road and then at me insisting me to let her "help me" till we got home after that she never brought anything up about it for a while till our patents went on their anniversary trip and left us alone for two days. This is were she began to tease me by wearing no short skirts and shirts that barely fit her (which she rarely dresses in.) When I watched TV she would now cuddle up next to me and begin to say things like "You know I'm not wearing a bra and our patents aren't home." I still just ignored her and tell her it's not right even though I am somewhat attracted to her. I knew that incest (might have spelled that wrong) was wrong and anyone who was caught doing that would be shunned were we live. I finally knew I had to get some advice recently when I took a shower and she took all the towels and put them in her room telling me to come get it, so I had to dry myself off with toilet paper and make some what of a towel out of it too. This is when I started asking my friends what should do and most of the immature friends said -blam!- her, so I thought of a different way without getting family involved and now I'm here asking you guys advice. What I should I do in this situation that doesn't involve me giving in? EDIT: So I'm going to bed and if anything happens tomorrow I'll add to this story below this edit and also more advice would be nice too, good night Flood
