While it was not Hal's first time seeing Emily naked, it was the first time he had seen her naked without her mask and it made quite the difference.
The first time may be likened to viewing a perfect painting and the face of the subject of the painting had not been added. In which case, the painting, while beautiful, would still lack character.
However, once the face is finally painted in, it completes the image or in Hal's case makes it look new and fresh to memory.
Emily was quite proud of her body but it was far from being the reason her heart was thumping so hard. The reason for that was the pleasure she remembered feeling from Hal's hands on her body and the orgasmic bliss it had brought.
While neither of the two suggested it, they both knew what would and should come next as Emily set up a massage table right beside the bed and lay on it with her Ass facing up and her head resting on her arms.
