I sometimes flash my father and pretend that it was an accident.
What were you doing when you flashed your father?
I was stroking my dick with a smirk on my face.
You should not flash people especially your parents. It can get you into a lot of trouble. Your parents might think you have some sort of problem.
Oh please. I'm using my limited freedom when I'm around him and it doesn't matter since I don't care.
It does matter unfortunately. It is wrong to flash your genitals at people. If you do it outside the house you could end up in jail or labeled as a sexual predator.
