Not a fan of femdom (btw, that tag is missing) but I gota admit that the "making her fall in love with a pussy dripping with cum" is pretty damn good. Too bad there isn't a tag for this or sexual orientation reversal, as problematic as that tag could get to be.
If anybody knows any good stories like that, I am all ears.
Because they are only in love with a given body part of the mistress and not to the mistress herself I see no reason why the slaves could not just overpower the mistress to free there "love".
