You'd be sexually abusing her and she'd be scarred for life.
actually don't do it well shes asleep when shes awake and you guys are alone go to her and show her how to kiss, then it can happen. don't do it while shes asleep. I'm sure she'll like it. just don't ask just tell her let me show you something, and do it.
I think you have a problem. If you do that to her, she will be mentally scarred for life. Its sick and perverted!!
Its natural to fell that way with your sister. I didnt have any sisters, but me and my female cousion started out early. We would play doc and house. An when I was 17 an her 16 we had sex. It was beautiful, because we where close do to family. It felt like we made a bond that cant be found anywhere else. My point is start small if she likes it more power to you. If she dosent then back off.
