When I was growing up I lived with 4 step-sisters all older then me. None of us got along. I would always get grounded or spanked because they would make up stories or strech the truth. I remember one time in the summer my step-sister that was the oldest (17) had a few of her friends over to go swimming in our pool. All of her friends were very hot. I was showing off in front of them and my other step-sisters kept telling me to stop. I kept it up and ran to the pool when they all went to the pool. Sarah (the oldest step-sister) had grabbed my arm as I ran past her. She then slapped me on my ass two or three times hard and told me that if I kept it up I would be going over her knee and she would tell my parents when they got home. My face turned every color of red and everyone was laughing at me because I was being corrected. One of Sarah's friends told me to stop acting like a babby and to start acting my age. I said ok and jumpped in the pool. We all started to splash and push each other under the water. One of Sarah's friends tried to push me under the water but I was able to get away from her. By accident I grabbed her by the waist and tried to push her under. Well she went under and didn't want to go under so when she came up she started to yell at me. She then told Sarah that I tried to take her bottoms off. Sarah grabbed my arm and puled me out of the pool. She found a chair close by and sat down. Befor I could do or say anything I felt my swimming trunks being pulled down. Sarah pulled me over her knee and gave me the hardest and longest spanking I had ever gotten. Everyone stood around Sarah watching and laughing at me. When the spanking was finnaly over she pulled me up and sent me over to the deck door. She said "Seeing that you think it's ok to take peoples clothes off and see them nude you can stand and face the wall with nothing on until mom comes home and then explain to her why you are nude with a red ass facing the wall. Well as soon as my step-mom came home and found me the way Sarah left me she demanded to be told what had happened. I told her and I was spanked again this time with a wooden paddle almost as long as the first.
