Is it normal to feel crazy attraction toward the step sister?
I'm 21, she's 17 and so sweet, petite and pretty. We've been living under the same roof for six month so far and it just gets worse, the feeling grows more and more intense and totally out of control. I know there are some legal issues here concerning the age, us being step siblings and stuff, but that's just not the matter. I think I'm terrifying her. Whenever we're alone she gets really nervous and tense. She avoids me, avoids talking to me, avoids any physical contact. I once heard her talking on the phone with her friend and she said I look like I "did some jail time" and that's just the way she feels and she's got "no reasonable explanation on that one". I was mad at her. Our parents are leaving soon for the weekend and I'm afraid of not being able to hold back.
