Sister's ass is twerking while she dries her hair

All the boys I know would give anything to see what I caught with my hidden camera while spying on my own sister. She is the hottest girl in the neighborhood and I really wanted to see her naked, so I caught her without her knowledge, while she was in the bathroom. She got fully nude and you'll love her gorgeous pussy and tits, but the best thing is when she starts to dry her hair with a towel. She bends over and wipes it quickly, which causes her perfect nude ass to shake like she is twerking.
