Here I am writing my experience!
My step-dad is a macho cop. A muscle man. Handsome, 6 feet tall and 176 pounds.
Dad caught me and my best bud jacking off each other in our garage, while looking at a nudie mag. He came to get me because the Army recruiter was on the phone.
I left in a hurry but my bud just continued to masturbate. My bud and me are both 19 and are enlisting in the Army.
Anyhow, I stayed away for an hour or so. When my bud came out of the garage he had a satisfied grin on his face. He didn't tell me what happened but I think you can guess, and I never asked.
What's private is private! as far as I'm concerned.
