Dear...

...Stepfather,

Your "office" is directly across the hall from my bedroom. When you look up porn "late at night" I can hear exactly what it is you're doing. Please do not delude yourself. I am not asleep. I am not unable to hear you, or whoever you are looking at. Please quit grunting my mother's name. While i'm glad she's the one you keep on mind while pleasuring yourself, it's still something that I'd prefer not to think about. Also, you're KY lubricant that you think is "well-hidden"... isn't. My 7 year old sister found it, and I had to take it from her and put it back in you "secret hiding spot".

That is all.

When he's whacking his Johnson around late at night, walk into his office and ask him what's good on YouPorn.
