HUNTA-931 "You have to pull back the foreskin and wash it properly!" 3~ My older sister, who always treats me like a child, pulls back the foreskin of my circumcised penis.

I have a much older and very beautiful sister who is extremely meddlesome, treating me like a child. She even barges in while I'm taking a bath and, upon seeing my foreskin penis, says, 'You need to wash it properly! Girls won't like you!' and tries to wash it for me. Being touched like that makes my penis instantly harden into an adult erection. I thought this was bad, but then she says, 'Hey... shall we do something more adult?'
