I do not want to know the answer to this question.
And you won't.
But the question will start to come back to your mind again and again.
At night when you can't get sleep you will try to repress the thoughts of whether it exists and what it would be.
Surely no one would want to see it?
And even so would he ever actually film it and release it?
There is no release from this pain because you will never uncover the truth.
At least finding out it exists would offer some kind of catharsis but you will never be certain because you rejected the truth once.
What would it even be? Would he have hired some actress or persuade his wife to make porn with him? Would he take a break every now and then to consume some of his MALE VIRILITY drugs and food additives that he sells?
At some point you think about googling it but dare not for the fear of actually finding what you seek and instead try to go back to sleep.
