Grizzley Undies

By Mutabear

Tired of his average body, Kevin decided to see what it was like to be a bear for a day. He got a special ordered pair of Grizzly Undies in the mail, which promised you a beefy bear bod for a full 24 hours. He slipped them on in the morning after showering one Saturday and the changes were immediate.

He quickly gained a couple of inches in height, and almost a hundred pounds of mass piled onto his frame within seconds. He watached in awe as his body filled out and thickened everywhere. He grew a huge bulging gut, thick beefy biceps, and calves that were almost as wide around us as formerly trim waist. Wiry hair exploded out of his chest, coating him entirely. Arms, chest, legs, back, groin…it seems like anywhere that could have a healthy covering of hair, hair was out in force. His beard was particularly impressive, nice and thick and well-maintained. as opposed to the dark brown of the rest of his body, it also had a bit of a reddish tinge to it, especially around the chin. His head hair started thinning a little bit, but overall he thought he looked great. Kevin was surprised that a couple of tattoos swirled and appeared on his body, but they looked a little faded and were clearly the remanence of a well-spent and adventurous youth. Kevin had made sure to order a special pair that left his mind unaffected, so he still had all of the cognition and faculties that he normally possessed. The label said he might feel slightly more relaxed and confident, but it suggested that was just as much a placebo effect of his new body rather than an actual change in thinking.

Having been prepared for the occasion, Kevin had purchased a few items to fit his new body, and he got dressed. He went to down to the gym that morning to see what his new form could do, and it didn’t disappoint. Despite the prodigious stomach, his bear body was exceptionally strong. He could easily surpass what he used to bench, and his squats were insane, easily going up to three full plates a side on the bar. Unfortunately, his new body did not improve his stamina to a great extent, so even though he was able to crank out rep after rep, he found himself getting tired rather quickly. As he finished his third set of dead lifts, breathing hard and sweating everywhere, a young frat boy walked over and complimented him on his form. Kevin looked at the guy and smiled. The young man looked like he had just woken up, with messy hair, a tank top with some Greek letters on it, and a pair of very baggy athletic shorts that were doing nothing to conceal the massive hard-on within. In fact, Kevin could tell the man before him was going commanding, and he felt his pulse quicken and blood surging to his dick. Kevin walked right in front of the guy and smiled, starting up a conversation with the frat boy. They The guy was on summer break, living at home while interning, but wanted to work off his beer gut he picked up over his last term. Chatted a little bit more, and wouldn’t you know it, both of them had just finished their workout for the day. Kevin suggested they relax in the sauna and share more tips, and before long young mr. frat boy was gagging on Kevin massively thick six inch dick. He joked to the man that it was almost as wide as it was long, but the challenge only semend to make the young man work harder to fit the wide piece of meat into his zealous mouth. The boy was a pretty good cocksucker, and it didn’t take Kevin very long at all to shoot. The frat boy tried to swallow his load, but Kevin’s huge bear balls were exceptionally full, and a few dribbles of jizz escaped, marking his face. They both laughed at this, since in the dark sauna it was indistinguishable to tell cum from sweat, and the boy thanked Kevin for the privilege of fooling around. It was already only four hours into the day with his new beefy bear body, but Kevin could tell he was definitely going to have to order a couple more pairs of grizzly undies…
