Sometimes he wants to feel his ass scorching, so he acts naughty to make me angry. It's because he wants to be sure I won't hesitate to spank him hard enough. Well, it works pretty well. I was spanking him through his joggers and underwear, Then I made his ass red by spanking his naked buttocks with my bare hands and belt. I could feel his hard dick, so I made him cum too on the bed at the finish.
