What Happens to Belinda for the First Time With Peter Rouse?

In the maze, Peter Rouse keeps going and Belinda gasps that she feels she is going to explode. Rocky then writes the line the hosts stop on: for the first time in her life, she was not in control. Jamie Morton calls that a big deal, because Belinda has directed every earlier encounter in Belinda Blinked. She is enjoying it "to death," and the hosts say she sounds like a changed woman. Peter sweats, she rubs his skin harder, and the scene ends with both of them climaxing. The first is not her first orgasm. It is the first time she is not the one in charge, and she likes it.
