You kneel at Goddess Candy Blades feet and beg to get a sniff from her sweaty socks. She knows well how badly they stink and offers you a chance to change your mind. You want to smell them anyway, so she kicks off her boots and covers your reckless face with bottoms of her dirty socks. They're not simply vinegary stinky, they're just too much for the human nose! But there's no turning back! Once she is out of her boots, you have to inhale her socks, even if you don't like their smell.
Madame Marissa likes to test new slaves before she employs them. That enables her to know them better. For this slave, she decided to use sock and foot smelling fetish. She had sweat in her shoes and her socks and her feet were smelling and sweating. And that is what she used to test him. She made him lick and swallow whatever he had licked. And he did it without question.
