My sister makes herself out as a victim because I put her laundry in the dryer

You are better than me......when I see someone's clothes sitting in either the washer (like you said, for hours after they have already been washed) or dryer I just take the clothes out, either sit them right on top of the washing machine/dryer or a chair, put my stuff in the wash/dryer, and when I am done with my stuff I just take the person's clothes and put them right back where I originally found them lol.
