Dad came back from his workout and when upstairs to have a shower. I passed his room, and noticed the door had been left ajar, so couldn't resist having a peek. I watched him strip out of his training gear, right down to his slinky briefs. He pulled them down a little, but then he stopped.
But then he looked up and stared at the door.
"If you want to see the rest, boy, then join me in the shower. You can see it up close before you take it in your mouth and suck the first load of Daddy cum from my balls.
