Thirteen-year-old Tom Sawyer woke up a little after midnight with a raging hard-on, which was not unusual at all. He had learned to jack off a few months before, but Aunt Polly always stayed up later than he did and got up earlier and when she was awake she had ears like a bat. So Tom had gotten in the habit of waking up in the middle of the night to take care of his pecker. He did it almost every night, sometimes even two or even three times a night.
By the light of the full moon shining in his bedroom window, Tom saw that his best friend, Huckleberry Finn was in his room. This was a coincidence, since Huck had been the one who first taught Tom how to beat his meat, but it was also not unusual. Huck often snuck in Tom's window, as quiet as the thief he was, to take Tom off on some hare- brained adventure, usually - but not always - managing to return Tom safely to his bed just before Aunt Polly called up from the kitchen for him to hurry up and come down for breakfast.
Two things were unusual. First of all, instead of standing across the room ready to flee back out the window as soon as Tom arose, Huck was crouched beside the bed with his face no more than two feet from Tom's. And the feeling coming from Tom's groin was not the slightly painful pressure of his peter pleading to be pleased, but was instead a somewhat familiar, though oddly different and thoroughly enjoyable sensation.
Slowly, Tom slid his hand down toward his crotch to find another, slightly larger hand already at work there. Instead of frantically stoking and pulling the way Tom did, Huck was moving slowly, gently squeezing Tom's cock as he pulled the foreskin up, then making sure each finger individually stroked his cockhead as he pulled the skin back down. Tom noticed absently that the older boy paid particular attention to the most sensitive area just below his piss slit where the head and shaft came together.
"Tom," Huck whispered, "you awake?" Tom was sure that Huck knew by now that he was awake so instead of answering he just let out a little groan. "You know I told ya how much I 'preciate you settin' me up at the Widow Douglas' house? I mean, I've 'bout had all the sivilisation I can take, but still, it's been real nice having a roof over my head and a warm place to sleep and all. Well I told you I'd find a way to pay you back one of these days, and I've finally figgered out how."
Tom smiled to himself. Back in the spring he had caught Huck with his pants down around his ankles, pulling his pud for all it was worth. He hadn't even known just exactly what was going on, but Huck had made him promise not to tell nobody and in exchange, he taught Tom had to get himself off. Ever since then, Tom had been trying to figure out a way to get Huck to play with his pecker, and now here he was, all on his own, doing just what Tom had been wishing for. Tom decided to lay back and enjoy it. Just as he closed his eyes, he heard the sheets rustling and felt Huck climbing into the bed with him. Tom's bed wasn't very big, but he guessed it was big enough for two young teens.
Suddenly Tom drew in his breath sharply as his brain processed feelings he had never experienced before in his young life. Whatever Huck was doing down there had gone way beyond stroking his cock. Tom's dick seemed to be enveloped by a warm, soft, wet, electric sensation that ran down into his balls, across his butt, and all over his body. His hands involuntarily returned to his crotch and found the top of Huck's head planted in the center of his body. Tom slid one hand around to Huck's face and there, to his astonishment, discovered that his own dick disappeared into Huck's mouth. His best friend was sucking his cock!
Tom groaned in ecstasy. He could not believe how good it felt as Huck ran his tongue across the head of his dick and bobbed up and down the shaft slowly, then faster and faster as Tom ran his fingers through Huck's shaggy hair. Huck's fingers toyed with Tom's balls, then began fingering his asshole as Tom involuntarily began raising his hips, bringing his dick up as Huck's mouth went down. As they settled into a fast, steady rhythm, Tom felt as though he would explode with each thrust. He was briefly afraid that his friend might be mad at him if he spewed his come out into his mouth, but then Huck began squeezing his balls tight with one hand and pressing a finger on the other up into Tom's ass and there was no more holding back. Tom arched his back with a low moan, forcing his little pecker as far up into Huck's mouth as it would go, then pushed down on the top of Huck's head forcing him to take it all the way up to the balls, and exploded with an incredible force, firing several volleys of jizm into Huck's mouth. Far from being angry, Huck swallowed greedily and, even as Tom began to relax, continued bobbing up and down on Tom's pole until the very last drop was wrung out. He had managed to swallow most of it, but a few drops had dripped down onto Tom's hairless balls and Huck finally released Tom's dick with a slurp to lick them up. Tom felt a shiver go up his back as he did and produced one last little drop of come which fell on Huck's cheek. Huck looked up and grinned, but left it there.
"So," Huck said, "I guess we're even now."
