When a male and female are having sex in the doggie-style position and he spits on her back to make her think he is finished she turns around because she thinks he is done, and then, he goes on her face with an open mouth. Some of his semen gets stuck onto her teeth and dangles, hence, tooth juice.
This girl was so wet with tooth juice I began to throw up.
