No you are just having your typical fag fantasies
So Brian,
So far the story makes sense. He is a friend of your step daughter and you see him in the gym. Normal
Yesterday, you decided to say Hi, I am Brian Wood Healy Hankins step father to XYZ..
Would you like to take a picture with me so i can post it online on a muscle forum?
Sounds like perfectly sane 45 year old male behavior.
