When younger, my sister played with my cock when she thought I was asleep. I woke because I thought I heard something in the hall outside my room. I could see a shadow next to my door so I closed my eyes wondering what was going on. All I had on was my white jockey underwear and I was laying on my back. Keeping my eyes just a hair open I watched my sister creep in. She got on her knees next to my bed and lightly put her hand on my cock. I didn't move and watched her lick her lips. She pinched the edge of my underwear and pulled the front down. My cock was rock hard I figured she would see it and figure I was awake. She touched the head and slowly wrapped her fingers around it. I stayed still which was difficult because I wanted her to pull it or suck it. She played with the head and ran her hand over my shaft, then put my underwear back and left my room.
