The Monk uses the fuck machine to administer a unrelenting anal punishment to nurse Sierra Tight little bunghole. Crying and begging does no good and if the machine comes out of her tight little ass then the monk uses his paddle to punish her. Nurse Sierra begs the monk to stop the punishment but Monks of the order of De Sade are not know for showing mercy, the punishment goes on and on until Sierra learns her lesson. I think that it is a safe bet that she will remember her stinging bottom and sore butt hole before she disowes the rules again.
