This girl was extremely unpleasant and these mistresses did not want to let her continue being unpleasant especially because she was interested in joining their group. After being with her for a short while, they felt that people did not tell her to her face that she was unpleasant and had to change. So they humiliated her by trampling her and having her lick their feet, socks and sneakers to make her realize she had to tone down and stop being unpleasant.
