Jack's main reaction to that continued appraisal of his body was mostly amusement too. He smiled a little more widely, very confident that Andrei would like what he saw, even while he was also reacting instinctively in other ways: a faint flush colouring his cheeks, a slight quickening of his heartbeat, a very definite sharpening of his attention as Andrei began to obey his mistress. He watched the disrobing with a very similar appraisal to that which Andrei had been giving him, and with a similar appreciation of physical beauty. He also watched Nora watching Andrei, because that was something new, and very enjoyable.
