And now:
Stay at your place, hold still and well present your taut tush!
We have to take your temperature and must shove these old fashioned rectal thermometer deep in your rectums and during that we don' want to hear any noises from you!
After you will behave, as we await it from you, you will get your reward and will be allowed to moan into your muzzle gag for sheer arousal or you will scream into your muzzle gag during you will get know my riding whip;-)
