Sister

The first time I saw my siter masterbate. I was 18 and had been out to college party. I came home late and went to my room quietly. I got undressed and put on my night shirt. I then layed in bed and started to relax. I could hear something in my sisters room. I was not sure what it was but after a minute I deccided to check it out. I got up and went to my door and opened it and went to her door. It was ajar and I looked in. All the lights were out in the house but I could see shadows from the street light shining in the room. She was moaning slightly and I could see her hands aand arms move under the cover. I quickly knew that she was touching herself. I decide to continue watching.. Ater a ccouple minutes it was obvious she was excited and enjoyed wwhat she was doing. I watched until she moaned louder and appeared ti stiffen her body under the cover. After a few more seconds I quietly went back to my room. I got in bed under the covers. I was wet from what I say and heard. I soon started touching myself. To keep quite I layed on my stomach and buried my face in a pillow. I did not stop touching myself until I orgasmed. It excited me so much to touch myself and think about my sister doing it too.
