Naked Festival in wife's home town

The protagonist and his son were to attend his wife's local naked festival.
While he was enjoying the festival, feeling embarrassed about parading through the town
wearing only a loincloth, his wife said something surprising...

"Actually... after this purification... you're supposed to do it naked..."

He has a much smaller penis than the average man...
His wife tries to keep her husband's secret from the rest of the audience,
but will they be able to finish the festival in one piece...?
