Brotherly Rivalry

Okay, hope you lot were at least a little satisfied with that last one. You might find this one more to your liking, or not. Either way I hope you enjoy the things Jeremy is learning about his toy, and himself.

Anyway, on the the next chapter.

Accidents happen in life. Jeremy and his oldest brother shared an accident one day. One that hugely embarrassed Sam but led Jeremy down another path of discovery.

It was nearly inevitable. This one was mostly Sam's fault, although he'd never admit it. You can't grow up in a three bedroom house with three other brothers and not have some kind of privacy issues. He still should have locked the door like he usually did. That little oversight cost him.

Yep, you guessed it. Jeremy walked in on him while rubbing one out.

Jeremy got an eyeful too, so to speak. He couldn't help but stare in shock. No really. After all, what kind of training does one get in how to react when walking in on someone taking action in a little self-satisfaction.

"Get the fuck out." Sam ordered at his shocked brother. Sam in two steps had shoved the door back closed on Jeremy. In the process he gave his brother a full view of his equipment.

As Jeremy recoiled from the slamming door his first thought was that they weren't much different. Their erections were approximately the same size. His second thought was of course that he wanted to be bigger than his brothers in every way.

Only a little over a month into summer vacation and Jeremy had already passed his brother Eric in size. In the occasional wrestling match that broke out between brothers Jeremy knew he was almost a match for Ian in strength. He still had another inch or two to catch up to his next oldest brother in height but that would just be a matter of time.

Now the real challenge in Jeremy's mind was besting them all in the male-hood department.

He spent the rest of the day avoiding his enraged brother and searching through the menu of PATOMES for a solution. If he could add mass to himself as mostly muscle then he should be able to target a single body part. At least he hoped.

Six hours he searched through the menus of PATOMES. He learned a lot in that time of intensive searching. He was truly surprised and more than a bit pleased at his findings. Best of all he found how to target a single organ in the body for the addition of mass. First though, he would have to experiment on something other than himself. He would have to perfect his technique like never before. There was no way he was going to put his own cock on the line.

Trouble was his favorite subjects were invisible in that department. He'd have to find another animal to test the targeting formula on. One that clearly displayed its equipment. Squirrels though, they put it all out there for all to see under that bushy tail of theirs.

By the next morning he thought he had the right adjustments set in PATOMES. He borrowed his fathers binoculars and biked over to the park. Selecting an out of the way and heavily treed area he set up shop. He first tried to target the little animals through the binoculars. With the failure of that test he learned he could target by unaided sight only. The binoculars would still be useful after activating PATOMES on his subjects.

Not to be defeated he continued looking for male squirrels to target without optical aid. Fifteen minutes of waiting finally yielded results. He was to say the least disappointed. He couldn't see anything past the thick tail fur.

Considering his options a moment Jeremy decided to go with his test anyway. With PATOMES he was able to examine the proportions of the squirrel under the fur anyway. He targeted the male and in a few commands added mass to his member. The little squirrel jumped the first moment of the transfer. It continued scurrying about the tree limb even as his penis enlarged within him. For three seconds the squirrel's member grew. It sent the little animal literally up the tree.

Jeremy couldn't see the squirrel but he could know the effects through PATOMES. The little fella now had a member four times larger than it had been. Once he settled down the male seemed perfectly healthy, at least he wasn't dropping out of the tree. Jeremy had no idea what he was doing way up in the branches. His subject for today was far too high to be seen. He waited for several minutes as it settled in to living with an oversized specimen.

After a few more minutes Jeremy added more to the squirrel's already outsized cock. He could hear the male in the tree. The growls of squirrels were fairly unique. They often growled aggressively at passerby. His subject was clearly disturbed. The squirrel soon had a member eight times the normal size for a squirrel, assuming it had started off as normal. It still stayed high in the tree.

Jeremy searched through PATOMES for any additional information he could glean about the state of the squirrel. He was still looking through the menus when what must have been his test subject came low enough to be seen.

Jeremy could see the pink flesh of the squirrel's penis under his belly. The massive thing reached to his chest. He was forced to lift his back end higher just to waddle around his huge member. It wasn't even erect and it looked abnormal in its massive size.

Jeremy could never go around with anything of the same proportion to his own body. Still he had learned one thing. He went through the options and with some fine tuning added to the squirrels body again. In the few seconds he'd set for the change the squirrel skin and fur grew to cover and envelop his enormous shaft. It now looked like a squirrel with a massive sheath, one far beyond normal for a squirrel.

Satisfied with his test he went to an option he'd found in his search over the previous day.RESET EXTERNAL SUBJECT #2915READY

Jeremy activated the reset option and watched as the squirrel again scampered about. He smiled when it was finished. He wouldn't have to go through the trouble of carefully retracing his steps in changing the squirrel, or himself. PATOMES could do that for him with a single order. He just needed to remember that anything he did change would be permanent after saving, until he changed it again.

He peddled over to the males restrooms again. Inside he took one of the stalls. Dropping his shorts around his thighs he looked at himself. Half hard already in anticipation he readied PATOMES for enlarging his own member. He waited until he was fully hard before adding any mass to himself.

Jeremy found why the squirrel had reacted to the growth of his penis. The three seconds he'd set for the growth of his penis felt incredible. Much like having an orgasm but so much stronger. It kept getting more powerful the more mass was added to him. Once it stopped Jeremy was leaning over and had both paws gripping his cock. He leaned against the stall walls to keep from falling over. Panting from the experience he stood slowly.

Looking at his cock he grinned his triumph. Three inches longer he was now almost twice as long as before. His thickness had increased too. Taking himself in paw again he shivered with the increase in pleasure. Stroking his thick shaft brought a groan from him. He could now wrap all his fingers around himself and still have room on his shaft to stroke. He was cumming in seconds.

Taking a bit of paper he wiped his cock tip clean and pulled his shorts up. He went over to a clean stall and waited for his now soft member to get back to its new normal size. In the privacy of his stall Jeremy used PATOMES to adjust the skin and fur around his sheath to fit properly just as he'd done for the squirrel and saved the new changes.

Satisfied with the fit of his sheath around his larger member he examined himself. He was clearly larger than before. His sheath had gained about an inch in length and was somewhat thicker, maybe a third of an inch. This was a victory he didn't need to wait for. Should they stand side by side his member was now larger than his older brother's. Looking at himself Jeremy decided he wanted to clearly surpass his brother. He felt it should be obvious to anyone that happened to catch even a glimpse of him.

As he stood in the stall someone came in to use the urial. Jeremy decided to add even more mass, he wanted to double his size again. His second try had worked wonders for his musculature, so he acted to conduct a second trial on his member. He adjusted the command in PATOMES to add to his member and sheath at the same time. It took a bit of extrapolating from his own history stored in PATOMES but by the time he'd finished the person using the urinal had left. Alone again he was ready. He stood and turned his back to the stall door to watch his growth.

Still fully embedded in his sheath he triggered the command. Instantly he was growing again. The pleasure brought him to his knees. The five seconds he programed for his growth were stunning in their intensity. He was half hard by the time it finished. As he stood and looked at himself he was even more pleased. He was already larger than his previous change and still growing as he stiffened. Seven inches became eight as he grew up out of his sheath and continued growing. His cock also thickened, he felt the skin around the opening of his sheath stretching tighter as it gave way to his ever growing girth. With every second of his growing erection it seemed to grow that much faster from his rising excitement.

Once fully erect he appraised his new size. It looked like he was now an incredible eleven inches long, now far larger than his brother he stood out massive. He was so thick he couldn't wrap his fingers all the way around his shaft. Whats more he placed paw over paw on himself and his tip still showed an extra two inches past his grip. Looking at himself he saw that he had not simply enlarged, his cock and actually undergone a surprising set of changes.

He rose up stiff enough to actually aim right up along the front of his belly instead of out in front of himself. There was now a much steeper taper to the tip of his cock due to the increased thickness of his shaft. He was nearly three inches across and had about two inches of depth. He also marveled at the deep groove along the top of his thick shaft. It looked like the internal segments of his two sides had grown so much that they had begun to force each other apart. He had a large visible vein running the entire length of his cock which connected to a latticework of smaller veins wrapping around his girth.

He pulled one paw away and started stroking slowly. The pleasure was unbelievable. He'd added so much to his length that stroking along his greater self was far more stimulating. Even the increased weight of him in his own paw felt incredible. Speeding up he imagined his brother's face should he see his new size.

Jeremy laughed. He just might arrange for his brother to return the favor and walk in on him. Sam would see his little brother already had him hopelessly outmatched where it counted the most. That would put him in his place. With the thoughts of outmatching his brother filling his head he came against the bathroom stall wall.

He moved to the final stall that he hadn't cum in and waited for his member to subside and return to his sheath. It was a perfect fit for his new size, although it was perhaps a little tight but he liked the new feel. Instead of the simple little two-inch sheath he'd had Jeremy now sported a cock sleeve that was almost the length of his erection before the addition of mass. Before, he was small enough to point his cock out in front of his body when he got an erection, he now had so much extra length that his sheath hugged his body to where he now pointed up. Seeing his new sheath he understood why he now rose up along his belly when hard. The real change was in his thickness, he now looked three times as thick as he used to be.

Pleased beyond measure at his new endowment he pulled his shorts up and left the restroom. Even the feel of his thinker sheath in his shorts was different. He felt the fabric rubbing against the extra mass of his cock and sheath. He smiled at the gratifying sensation on his larger maleness.
