Short for Female Domination. The most wonderful form of BDSM. Unfortunately, it is made fun of in many movies.
The dominate one (Madame, Mistress, Domina, Dominatrix, Goddess) have complete control over the slave, such as:
-Riding the slave like a pony
-Put leash and collar on the slave
-Penetrate with strap-on
-Make slaves lick boots
-Dress up slave like a maid,animal, etc.
-Use slave for sexual favors
Some (BAD) dominatrices use slaves as "money slaves", and make them pay for everything. Usually scammers.
Mostly used in sexual games, but some people also have a 24/7 relationship, where the Dominatrix is in charge of her slave/s all the time.
In other words; femdom is most of the time amazing. Check out OWK.cz (Other World Kingdom) for one of the better websites. Other examples are "Whipped Ass" and "Men In Pain".
The slave was having second thoughts about Femdom, as he was bending over, tied up, getting whipped and penetrated.
