The troll gave a cackling laugh, and pulled back on the clothes he was wearing.  Stroking himself with unnatural fingers, he revealed himself.  A raging, ten-inch hardon...no, eleven inches.  Thick, and wriggling slightly.  The other monsters in the room laughed.  "I think it's big enough for you.  And my kind are blessed with...an unnatural vitality.  You will be serving me five or six times a day.  If you choose me."  She could see the troll was strong, but older, with a paunch of fat around the stomach.
