I've been called to see the headmaster, who informs me that poor Matron is ill and will be absent for some time! It means she won't be able to complete today's weekly knicker inspection, and I assume the headmaster wants me, as headgirl, to ensure everyone's in regulation white knickers. Indeed, he does want me to take this responsibility, but to my horror, he tells me one girl has been seen in a lace thong, and that consequently, he requires *everyones'* knickers to be checked, including mine!  I'm utterly shocked to discover that he intends to check mine, right now in his office. He instructs me to remove my cardigan and plaid skirt, which is hideously embarrassing; I've never been half naked in front of a man before! The orders me to turn in a circle so that he can check my knickers are appropriately modest, and then he does something Matron has *never* requested! He tells me I must remove my panties so that he can check the gusset! What can he possibly mean? Why does he need to check the gusset? I'm headgirl, for heaven's sake! Does he think I'm smuggling items in my panties or something? I'm extremely reluctant to remove them and expose my pussy and ass to the headmaster, who appears to be enjoying himself rather more than feels appropriate. But I'm in a desperate hurry to be allowed to put my panties back on, so I simply try to get through it as quickly as possible. And it's then, with my panties already off, that I discover that the headmaster's version of knicker inspection also includes an inspection of my body. He instructs me to bend over right in front of him, and touch my toes. My goodness, he must be able to see everything! I've never been so embarrassed in my life! And then, just when I think things couldn't possibly get any worse, he orders the unthinkable; to grasp my butt cheeks in both hands, and pull them apart to give him an unobstructed view of my pussy and anus! Unbearable shame!
