It's the next morning now. The boy still hasn't cum and is back on the bench. He's tightly gagged because his begging was becoming very loud. After a long teasing with brushes, I decided to see just how close I could keep him with the satin. This is the very end of that.
He was starting to get to the edge too quickly, so I altered my technique to slow things down. You could say I wanted to really drag out the approach to each edge π.
