I have a much older and very beautiful sister who even interferes in my private matters. To make things worse, she comes into the bathroom while I'm taking a bath and starts washing my body! While she's washing me, she notices my foreskin penis and says, 'You have to wash it properly! Otherwise, girls won't like you!' Then she tries to peel back the foreskin and gently, carefully washes it. She's already beautiful, but when she touches me like that, my penis gets hard instantly and turns into an adult erection.
