After a few slaps in the face, Sinstress orders Her slave to pleasure slave number 2. She uses Her hand to instruct him on how to jerk off his cock properly. He must stroke up and down while rolling over the tip. His balls must also be played with. Slave number 1 does such a good job that he makes slave number 2 cum from just his hand. Sinstress is displeased but not finished with either of them.
