Tommy was always low on the totem pole. He was shy, peaceful, and had an unimpressive build, making him the perfect target for bullies. He ended up spending most of his time in the library as a kid to hide from them.

He hit puberty late, and it wasn't kind to him. Other kids seemed to get ripped overnight, but all Tommy got was acne and a massive penis. Tommy's penis was truly something to behold, when it was fully hard it was over a foot long and thicker than a coke can. His testicles were also freakishly large, like baseballs dangling between his thighs, perpetually full of sperm.

Unlike most men with big penises, Tommy was perfectly capable of getting it up, in fact it typically got harder and stayed hard longer than other mens' penises. This was due to the fact that Tommy simply had more blood, and more efficient blood, than most people. The extra blood was conveniently stored in his penis, always keeping it at around half mast. It didn't take much to get it fully hard either, and when that happened, he would usually need to cum 2 or 3 times to get it down -- each time producing easily a pint of thick, sticky sperm.

The doctors all said it was just a one-in-ten-trillion genetic mutation, and it didn't seem to cause any serious medical complications. One joked with Tommy's dad that in a few generations, every boy in town might have a pecker like Tommy's.

As you might imagine, having a giant eternally-hard penis was uncomfortable and embarrassing for a scrawny teenager. He learned how to conceal it and control it as best he could, by taping it to his leg and other tricks, but even so it was impossible to miss the enormous bulge in his pants. Most people assumed it was fake until Leslie Greer finally confirmed its reality by sticking her hand down his pants and giving it a feel. From then on, Tommy was the target of lewd teasing by the girls of the school, forcing him to unload multiple times a day into the school toilets (much to the chagrin of the plumber). His bulge was also a perfect target for "love taps" from the male bullies, leaving him doubled over in pain. People sneered and called him "donkey boy". The few times he got any action, it was from girls who wanted to see how much he could cum. They wouldn't let him touch them, they would just jerk him off into a bucket and take pictures, which circulated around the school.

Although his social life was in the shitter, Tommy's incredible metabolism made him a star cross-country runner. With his junk properly secured, Tommy could run 10 miles in an hour no problem. It was this, along with his impressive academic accomplishments, that got him into all the top colleges.

College was an entirely different experience for Tommy. Instead of disgust, people in his res hall seemed to hold a sort of reverence for "donkey boy" once it was proved that his bulge was in fact real, and he had girls asking him for sex regularly. Unfortunately, Tommy had still not recovered from the sexual harassment he endured in high school, and he turned down all the horny girls who came to his door at night.

Kelly was one of Tommy's classmates. She had of course noticed the gigantic bulge in his pants, but she also noticed his shy, sweet personality. Unlike most of the girls who tried to get with Tommy, she wasn't crazy for big dicks, and she didn't try to bed him as soon as she got his attention. Instead she took it slow and got to know him. They dated for weeks before Kelly brought up the possibility of sex, and Tommy revealed his past and said he wasn't quite ready. They agreed that they would take a short backpacking trip over a three-day weekend and see if it felt right then.

Unfortunately, things didn't quite go as planned. They needed a permit for their planned trip, and when they applied for one it turned out that the permit limit had already been reached. Luckily, in a twist of fate, Kelly's best friend Bella had already gotten a permit for a similar trip, but Bella's boyfriend Matt had broken up with her just a week before their planned trip. Bella was heartbroken, and though she said Kelly and Tommy could go without her, Kelly insisted that she come with them so she could get away from it all. Bella relented and agreed to go.

After a strenuous hike into the wilderness, the three college students set up their campsite in a small glade next to a creek. It was just the beginning of fall, so it was pleasantly cool and the trees were just beginning to show their colors. The sun is just about to set and they sit around a campfire, Kelly and Tommy are already snuggled up and they're all laughing and joking and eating s'mores. Thus begins our story.
