His mother had warned him repeatedly about using the bridge on the north side of town, but Gregory dismissed them all as silly superstitions. Anyway, he was late for supper, and it was the quickest way home.
But as soon as his foot touched the first stone, a little green creature appeared, demanding a toll to cross its bridge. Normally, it would be for half the gold or food a traveler was carrying, but one look at Gregory and the Troll was instantly smitten.
Gregory, quite startled and not knowing what to do, quickly gave the beast whatever it demanded. First his shoes, then his shirt, and before Gregory knew it, he was completely naked. The Troll leered at the tasty young man's beautiful form and juicy cock as Gregory blushed, covering himself as best he could with his hands. He asked the Troll if he could cross now, but the drooling beast still wasn't satisfied.
Suddenly, Gregory found himself in its strong arms and, in moments, they were under the bridge.
It was after dark when the Troll finally decided it had had its fill of young Gregory, and sent the young man on his way.
Needless to say, Gregory would now make this his regular route home.
