Callie has always played coy with you when it comes to her sensitive feet, but seeing as it's a special day for you and her she's willing to let you get a little anniversary foot action! It's going to take just the right amount of tongue waggling and a precise measurement of toe sucking, but if you're up to the challenge then Callie will do you a solid in return and use those size 7s of hers on your rapidly hardening cock!
