My full blooded, 17 year old, little sister has been trying to seduce me. I came home from work yesterday and she was laying on the couch in nothing but a tube top and underwear. I was expecting her to jump up, thinking she was just lounging around and didn't realize I was on my way home. But she just lied there and looked at me, smiling. She said "come here and sit" and, hesitantly, I did. I was now sitting beside her and she put her hand on my..crotch and continued to smile. I immediately stood up and told her that she's crazy. That I am her BROTHER. And she merely said "I know, that's what makes it fun". Then this morning I was laying in bed asleep and she runs in the room and jumps on top of me and starts kissing my neck. I pushed her off of me and tried to talk to her calmly but she, once again, put her hand on my crotch and I picked her up and put her in the hallway and locked my door. I DON'T KNOW WHAT TO DO. Please, some advice here. I want her to stop, but I don't know how. Every time I try to talk to her, she becomes this sex-crazed woman with no limits.
