clip request:  Slave is laying under Mistress's desk when she walks in.  She is too busy to care that he is there.  The slave takes out his cock and starts masturbating.  But the Mistress automatically starts stroking his cock with her boots without realizing.  Slave sits back to enjoy the bootjob.  The Mistress jerks his cock faster and faster till he cums all over her boots.  Unfortunately for the slave, because she is so busy, she doesn't notice him cum and keeps rubbing his cock with her cum covered boots.  She manages to out another load from the slave's sensitive cock before realizing what's happened.
