I have a very beautiful older sister who is a lot older than me, but she is very caring towards me and still treats me like a child now that I am a high school student. As soon as she saw my foreskin, she peeled it off and tried to wash it carefully and gently, saying, ``You have to wash it properly! You won't be popular with girls!'' Then, when he got erect, he made a super erotic face that I've never seen before and said, "Hey... let's do something more adult!" !
