Me and my hot sister

I really want to seduce my sister. I know her account password and recently i saw her sending nude/bikini photos to other guys, and talking about sex when they meet eachother. I am so curious about this. I have her hot nude pics and can’t stop looking at that. Any advices how to have sex with her or seduce her? Also when we are watching movie or cuddling and I touch her breats and thigh near pussy she has no reaction and doesn’t stops me. She always wear hot outfits when she is going outside.
