What you don’t see in this picture is the block of ice she’s been standing on for a good little while now. Or the giant blue dildo mounted in her cunt. The ass hook firmly implanted and tied off to her elbows. Elbows that are themselves firmly brought together. Or the electrodes attached to her nipples.
I think this is the way you should look when you are about to have a massive, earthshaking orgasm. And believe me, she did. This image is rather symbolic really: The goggles implying the massive amount of cum she’s going to produce and the dental gag let’s you know she’s going to be eating it as well.
