The slave and his mistress at wichs training

I am in the process of raising a new slave. Unfortunately, he doesn't quite hear as much as I want. But that's what I'm there for that he learns to squirt and obey on command. Today, hour one is on the timetable. He splashes really horny on my overknee boots but he just doesn't want to stop with jerks afterwards. He still has to learn who has the reins in his hand. Let's see how the following hours go with him.
