Spider-man Never underestimate a man who was born in July shirt

I exposed my private parts in front of my 8 year-old-son with no underwear in the bottom unintentionally. I did not feel shamed about it since I thought he was my son. Actually he never looked at me when I was doing that. I saw him blinking his eyes or even closing them. He is a decent boy in this aspect. Now I never do that. Just for fun at that time.
