Pull his covers off
From Create Your Own Story
You move towards your sons duvet cover.
"Alex get up now" you say.
Still he doesn't wake or move he's still fast asleep. You grab a hold of the duvet and just pull it off him but doing so you realise his dick is rock hard and you 'accidentally' stroke it with your hand whilst removing the cover. You can now see Alex's dick without a duvet covering it up.
To your shock it looks bigger his dad's.
Do you?
