you don't like cheese but you love watching your step-mommy grate it. She teases you about not liking it and try's to tempt you to try it by rubbing it on her breasts and licking it off of her after you wont. You feel slightly faint, she shows her eating the parmesan cheese and it chewed in her mouth before she puts some of the parm in a bag and she masturbates with it until she feels you feel better. She does this several time until she is finished grating the cheese she needs as you watch her.
