You can look but you can't touch

Today is a test. You need to put your hands on the desk. You can only touch yourself if and when I say you can. I start taking my shoes off, they need shining - but you're not going to get the privilege of that, you can only look. I slowly peel off my stockings, down my long legs - slowly teasing - they've been on all day, there's quite a scent - but you don't get to smell, only look. I continue to tease you with my feet, my breasts, my legs, my arse.. Will I ever let you do more than just look?
