HHKL-066 The older sister bathed her teenage brother

I have a very beautiful sister who is older than me but she is very caring and took a bath while I did and washed my body! As I was washing my body, I noticed Ji Po had phimosis and said, "I have to clean myself! I'm not popular with the girls!" Even though I'm just beautiful, if you touch me like that, my cock will get erect and become an adult erection! My sister has a super erotic expression that I've never seen before...
