This giantess loves her big mouth because she uses it to crush and torture those she needs to punish. She wanted to have fun at the expense of this loser and that is what she did. This guy tried to con her but she realized before he did and she punished him cruelly. She teased him so that he did not know what she wanted to do and when she had him where she wanted him, she shrunk him and crushed him with her teeth.
