Salacious mistress knows that you can't stop fantasizing about your sexy her and her sexy body.
Certainly she knows you want to stroke your cock so she commands you to erotically stroke it through your pants as she pulls up her tiny white top and shows you her natural breast. She begins to give you the hot jerkoff motion with her hand as she encourages you to do it properly.
Your instructor doesn't want you to cum just yet she wants you to lay back and imagine her hand in-between your legs. Now its time for you to take off you pants and now you will stroke your cock to her instruction. She continues to pose for you as you stroke your cock as fast as you can. When you do finally blow your load, she comments on what a nice load you produced.
