What a good thing that the slave of Janine and Elaina is tied up helpless as practical. That way the two can spit at him as much as they want to. They begin with his upper body, this is covered with spit first. Then they take aim at his neck - and his face The two have a lot of spittle - and most of it lands in his face. They laugh at him, goad each other to spit on him even more and humiliate him to his shame. When they have enough, they simply leave the slave behind with his face full of spittle. The spit may dry on his face, they certainly don't care!
