Spanking amongst consenting adults is becoming increasingly popular in Asia - especially in Japan where numerous web sites on the topic are springing up. Unfortunately most of the sites are of the M/F variety but there are a few notable exceptions.
One of the most well known F/M spanking sites is owned by Ms. Nami. It's all in Japanese but relatively easy to navigate. Here you will find nice examples of her work in disciplining Japanese naughty boys and there is even a selection of her amateur video clips taken during the punishments. There is also a page with links to a number of other spanking sites in Japan.
