I seduced my sister one night when we were home alone by playing some porn,then massaging her shoulders while it played...then going to her breast,then going on and on,each step waiting to see if she stopped me,she never said a single word so I kept going..ended up being the most erotic experience of my life.shes married now but we still have sex whenever we get the chance.Would love to see it in a story,im just no good at writing.
