Watching My Step-Sister Toy Her Pussy

My new step-sister Aria Banks likes leaving the doors to our conjoined rooms open, and I've got a sneaky suspicion its so I can spy on her sleeping in those cute little pink cotton panties she loves to wear... and also to watch all the filthy naughty things she does to herself while our parents are out of the house! This has been going on for weeks now, and none of my friends would believe me, so this past weekend I borrowed my step dads video camera to get some solid, rock-hard, evidence. Right on cue, after waking up in bed and playing with herself over her panties a little, she grabbed the biggest double ended dildo I've ever seen, headed into our shared bathroom, and went to town on her perfectly moist 18 year old pussy!
