HUNTA-831-Uncensored-Leaked — "You have to pull back the foreskin of your penis and wash it properly!" 2 - My much older sister, who always treats me like a c**, pulls back the foreskin of my uncircumcised penis and washes it properly

I have a very beautiful older sister who is much older than me, and she's very caring. She came into the bathroom while I was bathing and started washing me! As she was washing me, she noticed my uncircumcised penis and said, "You have to wash it properly! Otherwise, girls won't like you!" and started pulling back the foreskin and trying to wash it gently and thoroughly! She's already beautiful, but with her touching me like that, my penis quickly became hard, turning into a fully erect adult penis! My sister had an incredibly erotic expression on her face that I'd never seen before...
