The cleft between my legs transformed as well. It lost a certain outrageousness, an obscenity, or achieved an obscenity of a different sort. The flaps seemed to open not to a narrow, snug dead end, but to something yawning. The passageway became a route to somewhere else, a real place and not merely to a darkness in my mind. The twist of flesh in front took on a devious aspect, its inclusion overtly ulterior, a tempter, a sweetener for doing the species’ heavy lifting, like the lollipops I once got at the dentist.
