After climbing under the thin blanket, Finn was asleep within minutes, and snored softly. Stork, on the other hand, remained wide awake. Each rustled branch, crunching leaf or faraway animal noise made him jerk his head towards the sound, and only served to enhance his feeling of dread. As Finn slept next to him, all he could do was stare into the darkness, terrified.
Finn had been tossing and mumbling in his sleep for a while now (which only added to Stork's anxiety), but for the most part Stork had ignored him, trying to keep a keen ear open for large predators. At one point Stork was trying to tune Finn out because he could have sworn he'd heard a giant spiny sloth (its sole nativity to the Black Gorge notwithstanding) when Finn gave him quite a scare. He rolled over in his sleep and his arm draped across Stork's chest.
Stork squeaked at the contact, thinking the sloths were attacking, and then realized it was only Finn. His pale, bare arm lay on top of the blanket, which Stork was holding up to his chin with both hands. Stork turned his head to look at his blond shipmate, and Finn was still asleep, breathing softly mere inches from Stork's face.
Stork was a little surprised at being trapped like this, and a little embarassed to try to figure out a way out of it. He thought about rolling over, but was afraid he'd wake Finn up. His elbows were also under Finn's arm, so he couldn't really move his hands to lift Finn's arm up off of him. Realizing he still had the blanket in his hands, however, he decided he'd simply lift the blanket up, and Finn's arm would slide off.
As he slowly raised the blanket over his head, he felt Finn's arm start to slide down, but just when he thought he was successful so he could get back to listening for any approaching horrors, Finn's arm stopped when his hand landed squarely in Stork's crotch.
