Oshiritataki (Japan 1980)
A schoolgirl has to bend over a table for a spanking from her teacher for unruly behindhand, first on the knickers and then on the bare backside. 22 spanks are administered firmly. The first 8 spanks are shown clearly from a side view, then when she bares her backside the first 4 spanks are shown from the same side view, and for the next ten her facial expressions are highlighted.
