Arno is a new 21-year-old student who has never been spanked before and he is already in trouble with the Master, and this has earned him his first punishment. Arno is amazed at the request of the Master to have him suffer a punishment with a spanking while being naked, but in order not to aggravate the situation Arno quickly accepts that there is no more escape and that he must bear his just punishment, with the added humiliation of having to be naked during it. After a painful hand spanking while languishing over the Master's legs, Arno is further humiliated by having to do uncomfortable physical exercise also while naked.
