Surprise

Not the way I wanted to find out but I now know my teenage son is gay. Long story short my wife was out of town yesterday, I was supposed to work until 8pm, but I cut out around 5pm.
As I started to open the door I could hear my son screaming. I panicked, thought he was in trouble, robbery, something? I ran inside, turned the corner into the living room to find my 16 year old son and his best friend naked. My son was bent over the arm of the couch and his best friend was fucking his asshole. They were so into it and my son was being very loud and it was obvious he was enjoying it. They didn't hear or see me until I was right on top of them. They freaked, grabbed clothes and took cover. I now know they are actually dating. Don't care as long as he is happy.
