My beautiful, nosy sister always treats me like a kid. She even started to tell me how to wash my body, saying, "If you don't wash it properly, you won't be popular with girls!" She peeled back the foreskin of my penis and washed it gently and carefully. It felt so good that I ejaculated on my sister's body, and she got excited too, and in order to make me a man, she let me touch her big tits and bouncy ass as much as I wanted and cum inside her many times!
