Well, whether too serious, or just too pushy with my teasing, I got a brief but sharp reminder to be a bit more respectful in the future. (We have no rule forbidding teasing, because we both enjoy it. But everything still needs to be 'friendly'. She found my teasing sharp and hurtful.) It was not the worst spanking I've ever gotten, but she wasn't playing either, and she scolded me very emphatically to never say the kinds of things I had said to her.....joking or not...........again.
Misbehaving men....an age-old problem.
