[Philip Lelyveld comment; there is a long story in today's (8/4/13) LA Times about The Canyons, an ultra low budget legitimate movie staring James Deen and Lindsey Lohan written by Brett Easton Ellis.]
Given that Glass has been in the wild for some time, we're extremely doubtful this is the first X-rated video made with it. It is, however, the first professionally-made one we're aware of, especially with breakout star Deen involved. The glasses themselves were apparently obtained from Motherboard's Arikia Millikan, who attended the shooting, and adult app company MiKandi — whose first attempt at working with Glass was abruptly stymied when Google pulled its "Tits and Glass" app after only a few hours.
... as the scene progressed, Glass itself started to heat up. That's not innuendo. That's what happens when you record for too long.
