A Lascivious Eye?

A trusted friend remarked today that he would never ever look again at sensuality through that lascivious eye, which, to the chastity of my own mind was quite unknown to me, a reason then to delve into the subject with some science. The magnifying glass was found at last, it showed (eventually) the little fellow's bod, but try and try again, much as I might and did desire to uncover this strange eye, all efforts were to no avail, there was a hump, or should we call it ridge, a hue of blue, and like a Loden coat a drape of flaccid skin was keeping civil temperatures, for sure, within. But that was all, there was no eye, so should I cry?
