For those who like discipline during examination, I can guarantee them they would have been happy if they had been forced to report in front of a military doctor in a physical exam for military service.
He was very strict with a stern look, he used always the familiar "tu" when he gave me orders, he never smiled during the exam, he gave instructions with a strong voice as if he was shouting, he gave me a slap on the buttocks when I was standing back to him while he ordered me to bend over and to spread my cheeks, he shouted "more larger" and he gave me an other one, more stronger when he had finished his visual inspection of my anus and wanted me to stand up again, he ordered me to tighten firmly my cheeks, then he pinched them to check they were enough tightened, and eventually, he gave me two other slaps, one on each cheek before saying I had a cute, firm and rounded bottom but he was not joking while giving his comment about my cheeks, he finished this part of the exam by a real whack on my buttocks to order me to turn around.
when it was finished, we should stay in a row behind against the wall like as standing at attention, with our arms on the side without talking and watching the exam of the others which was the same with some slaps on their cheeks.
It was a great surprise for each of us, we expected to be naked for some part of the exam but not for a so long time and we did not expect to receive slaps! so it is not always useful to have imagination!
