Madame Ellen was bored out of her freaking mind and she had to find something to do for fun. That is why she opted to get this guy to cum. So she took him to her kinky room and she had him watch as she played with dildos and strapons. He was then asked to do what she had done until he came. He was to follow her jerk off instructions.
Madame Ellen had given this guy jerk off instructions but she did not like how he did it. Instead of him doing it the way she had asked and showed him, he did his own things and for that, he attracted her wrath. The mistress punished him with a whip and she had him redo what he had done so that he strictly did what she wanted him to do.
