Imagine you're in your KARATE class and you're walking in and thinking it's a normal KARATE class, but it's just you and your SEXY ROCK GIRL INSTRUCTOR. Since you are alone with her and feeling brave you ask her to tech you how to MASTURBATE. Your KARATE instructor SIERRA tells you to sit down and pull your cock out. You sit in front of SIERRA and listen to her INSTRUCTIONS as she DEMONSTRATES on her DILDO. Listen to SIERRA and STROKE your COCK just like she says until she counts you down to cum.
