Goddess Lena hates people who are too full of themselves. This guy was one such person and she could not let him get away with it. She had to cut him down to size and keep his ego in check. She used her stinky socks to do it. He had no choice but to lick them until they were as clean as she wanted. The poor guy had no choice but to do as ordered and he learned the value of humility.
Goddess Lena wanted to dominate this loser and get him to change and act the way she wanted. So she went ahead and she forced him to lick and smell her socks and her sneakers. The mistress enjoyed watching how he was degraded and how he cried and begged her for mercy. He almost cried as she humiliated him and at the end of the day he told her that he would do things as she wanted.
Goddess Lena noticed that her slave had not changed the habits she had given him time to change. He was still doing the things that angered her and she chose to approach the problems in a different way. Goddess Lena chose to make him lick her stinky bare feet as well as be her human ashtray. The pain and humiliation of it did the trick and he had to change.
