The other day I got off from early from work and decided to visit my sister at her apartment. The door was unlocked so I let myself in. I called out to her, but no answer. Then I heard her singing in her bedroom. When approached her door I noticed she had on her headphones and was dancing in her bikini p****** and with no top. I couldn’t believe how smoking hot she looked. My eyes were glued to her s*** shaking a** and her bouncing t***. I didn’t want to interrupt her and I couldn’t lose this moment, so I videoed her on my phone and left. During that whole time she didn’t know I was there, because she was dancing facing away from me. I never knew that I’d get turned on by my sister, but she sure could dance s***. Now I cherish that video and I’d like to get more.
