When i was about 12 years old i started going through puberty. And my penis staryed getting larger. And one day i was useing the bathroom which i was sitting on the toilet and my sister who was 16 and somking hot knoked on the door saying hurry up and that she had to go too. So i decides to just stay in there just to see what she would do. And after about ten more minutes she couldnt hold it any longer so she barged in on me and said if i didnt get up she would me on me.
