The slave lied to Mistress Artemis, then didn't even apologize right away. That is one of the worst things a slave can do, still, Mistress Artemis chose not to punish him in a traditional way. Instead, she restrains him tight and silences him with a ballgag. The scared slave can only imagine the worst, but instead he actually receives a hot handjob. Mistress Artemis isn't that generous though. After the slave came she keeps working on his hard member, making him come a second time, even if he doesn't want to.
