My stepdad used to spank me for anything he wanted to including being late for dinner or getting a bad test report when mom was away. When i turned 11 he started making ordering me to stand right in front of him as he sat in his exclusive recliner and i had to drop my pants and undies and stand still. He would explain why i was wrong in a very slow deliberate way and then i had to turn sideways so he could easily swat my bare butt. He then would warn me about telling mom about this or it would get much worse.
