While I've been sick I've entertained myself with sketching softcore femdom inspired by different cultures. You don't see much Viking femdom, which is a shame because it actually works quite well with the culture.
For one thing, the men would go on dangerous raids risking their lives to bring back treasures, but as soon as they came home they had to hand it over to their wives. You see, women were in charge of the household's money because they were believed to be magic and have the ability to see into the future, but more about that later.
Also, the men did their best not to anger their wives because they had the ultimate weapon: divorce. It was a great shame for a man to have his wife divorce him.
Men weren't even allowed to touch a woman's hand if she had not agreed to it or he would be punished by law.
so long story short, Viking men did not mess with Viking women, and some women used that. ;)
