He doesn't have to be afraid of Lady Mara, does he! She only uses him as a human pony and just wants to ride him. As long as he obeys her nothing untoward will happen to him. If not, she has to punish him, of course. In her tight sexy hot pants she sits on top of him. He should feel honored that she even sits on him and uses him as a pony slave, instead of complaining, right?
