My folks had a two story house . It had the old doors and big key holes . I had just turned 13 . Just was getting into girls. I was up stairs in my bedroom. My sister had just gone into the bathroom! I went and peeked through the key hole. I saw her standing in the tub taking a shower ! I unzipped and was starting to stroke myself. She turned off the water . I went into my bedroom. I left the door open . I took off my shirt and pants . Standing there with a hard on bulging my underwear. I heard the bathroom door open . It creaked ! My sister was coming past my door ! I said hey ! Is there something wrong ? She stopped entered my room . She didn’t say anything. I pulled my underwear down ! I said I didn’t know what’s going on? It’s really stiff ! I’ve never had this happen before ! She touched it and gave it a stroke . She said it was ok! It’s something that happens to teenage boys ! I asked if it was supposed to be getting wet ? I put my hand under my dick ! Look it’s starting to leak ! She bent over . I could look down her robe . I saw her boob ! She touched it with her hand under it and stroked it ! That did it !! I squirted cum Into her hand . I said do I have an infection? She said it will be okay ! It’ll go down now . It happens to boys as they get older . She left ! But I was happy being stupid ! And getting her to get me off without her really knowing I did it to the neighbor girl behind the garage!! That was one time being stupid payed off . Yes I did jack off a couple more times . But she knew what I was doing it for her to watch . See the other blogs
