The moon was hanging high in the night sky, and most people in the neighborhood had already gone to sleep. However, one kid was still awake, tossing and turning in his bed. Joseph stared at the ceiling from the top bunk of his bed. Lately he's been having some growing pains, mainly in one particular part of his body. It has been happening a lot more often recently, especially when he's trying to fall asleep. It's not like he's never had a boner before, but these seem to stick around prevent him from getting any rest. Rubbing his face with both hands, he groaned. The bulge was making his tighty-whities uncomfortably tight. If he could just let it out for a little while... He sank down under the covers, having some naughty thoughts. Slipping his hands under the waistband, he carefully began sliding his underwear down. Almost as soon as they got below his crotch, his erection sprung out and stood tall under the blanket. Letting it out definitely relieved some of his discomfort; he hoped it would help make his boner go down faster too. He tried to relax again, but having his underwear around his knees felt unnatural. So he reached down again and pulled them the rest of the way off. Spreading his legs, he basked in his newfound freedom. Being naked except for his shirt felt so nice, but he knew he couldn't sleep like this. His parents have gotten on him before about his nudist tendencies, he was sure they wouldn't approve of him sleeping with no pants or underwear. But in the meantime, at least he could enjoy the comfort while he waited from his erection to subside. A few minutes passed, but so far there hadn't been any changes. He grew tired of laying on his back, so he rolled over onto his side and faced the wall. As he was moving, the tip of his bare penis brushed against blanket, sending a jolt through his body. All of his muscles tensed up for a moment; it didn't hurt, but definitely felt weird. Joseph reached under the blankets again, this time wrapping his hand around his manhood. It was still stiff as a board, and really starting to get on his nerves. He tried pressing down on it, trying in vain to push it back into his body. Worried that he might hurt himself, he stopped and instead just massaged the tip with his thumb. Once again, he began to feel the same weird sensation from earlier. It still made his body tense up, but something about it still felt kind of nice. He continued massaging himself a while longer, enjoying the way it made him feel. He wasn't sure if this was helping make his boner go down or just making it worse, but part of him really didn't care any more. It was like he didn't have any other cares in the world... At least, until his hips suddenly thrusted forward. As soon as it happened, he snapped back to reality and let go of his privates. He wasn't sure about what just happened. His hips just moved on their own; he didn't have any control over it at all. As he was worrying over that, he heard something soft fall and hit the ground. He rolled over and looked over the edge of the bed. Down in the middle of the floor was a pair of his underwear. Was that the same pair he wore to bed? He checked around under the blankets, but couldn't find them. All he could figure is that he must have accidentally kicked them off the bed. Joseph leaned over the side again and looked into the bunk below. Jason was sprawled out on the bed, his face turned towards the wall. It was hard to tell due to the darkness, but it looked like his older brother was asleep. Joseph checked under the covers one more time, this time at himself. His little man was still standing at attention, and he had nothing to cover it with. He needed to go retrieve his underwear, he just hoped that nobody would catch him. Kicking off the covers, he slowly crawled down to the foot of his bed. The whole bed would creak at the slightest movement, so he had to be careful. Once he made it to the ladder, he turned around and started climbing down. He was getting nervous now that he entire lower half was completely exposed. If his brother woke up or anyone walked in, he would have no excuses. He also had to be careful while climbing on the ladder, making sure his stiffy didn't hit any of the rungs on the way down. After he stepped off onto the floor, he crept over to his underpants and bent down to pick them up. But as he was standing back up, he heard some shuffling next to him. Jason was resituating himself, rolling over towards his younger brother. Joseph froze up, clenched his eyes shut, and prepared for what was coming... but instead, just heard soft breathing. He opened his eyes again to see his brother's face pointed directly at him. But luckily, his eyes were closed, his mouth was slightly open, and his arm was dangling off the side of the bed. Joseph let out a big sigh of relief; Jason was still asleep. >He carefully crept over to his underwear and grabbed them off the floor. >As he stood back up, he took another look at his brother. >Jason was facing right towards him, but his eyes were closed and his mouth was slightly open. >It appeared he was still asleep. >Satisfied that he hadn't been caught, Joseph made his way to the bathroom. >Once inside, he quietly shut the door and turned on the light. >After his eyes adjusted to the brightness, he looked down and checked himself again. >Still hard as a rock. >He laid his underwear on the counter next to the sink, then walked over and sat down on the toilet. >He began fiddling with his penis again, gently examining it with both hands. >He still couldn't figure out how to make it go down. >He wasn't sure if all of the touching was helping or just making it worse. >His fingers brushed against the tip, and once again his body tensed up and he felt the same weird sensation from before. >It was making him curious. Why does it do that? >He knew he wasn't supposed to play with his privates, but he getting really curious. >Everyone else in the house was asleep, and given that he was in the bathroom, he didn't have to worry about anyone checking on him. >This was about as good of an opportunity that he was going to get. >After considering it, he continued rubbing his fingers against the tip of his penis. >His body started tensing up again, but he kept going. >Last time his hips moved on their own, so he wanted to see if it would happen again. >The feeling kept getting more and more intense, and soon enough he began squirming on the toilet seat. >He moved one of his hands to hold on to the seat, but kept rubbing with the other one. >His breathing was getting heavier, his heart was pounding, and he was starting to get sweaty. >He couldn't fight the urge to lean back, but he was worried he might scoot off of the toilet into the floor. >So he stopped for a moment and came up with another idea. >He stood up and pulled his shirt off and tossed it aside. >Looking at the mirror, he admired the naked cub who was smiling back at him. >Sitting down on the floor, he leaned back and placed a hand on his privates once again. >The exploration resumed, this time with his hand running up and down the entire shaft. >He laid back further and closed his eyes, letting the feelings wash over him. >Something about it just felt so natural. >When he opened his eyes again, he looked down and noticed he could still see himself in the mirror. >It was funny, he had never seen his underside from that perspective before. >He spread his legs so he could get a better view. >Now he could see a bit of everything: wiener, balls, and even the bottom of his butt. >His gaze was locked on the mirror as he continued to touch himself. >Watching the boy in the mirror squirm around while rubbing his erect cock was making him feel even weirder. >He began panting and stroking himself even faster. >It was getting really intense now, he could feel his insides quivering. >He grit his teeth and let out a tiny moan. >His hips were thrusting again, just like earlier in bed. >His mind was racing, trying to deal with so many conflicting feelings. >Wherever this was going, it felt like it was reaching its peak. >Suddenly, his mind went completely blank. >All he felt was a sense of euphoria as all the tension in his body was released. >He laid back and started panting, exhausted by the experience. >But his penis was going haywire, acting like it never has before. >It felt like it was squeezing and pumping itself, like when he tries to squeeze out the last bit of pee after using the toilet. >After recovering, Joseph sat up and looked at his privates again. >He was concerned about that weird thing it did, worried that he might have broke his wiener or peed himself, but everything looked fine. >In fact, it was starting to get soft again. >He wasn't sure what just happened, but since his main problem had been fixed, he decided it was time to get dressed and head back to bed.
