Getting Sweaty (Patreon)

Based on a request by Valagon37

Jake desperately wished he could rewind time twenty-four hours just so he could convince his past self to take a rare rest day from the gym. Of course, his past self probably would have laughed the idea off - Jake McCosta didn’t take rest days - but he at least might have had his guard up enough to stop what was about to happen to him. Unfortunately time travel was beyond Jake’s abilities so he remained trapped within the unique prison of his own body, forced to watch as it was operated like a vehicle by one of his least favourite people.

Considering his Herculean body, Jake was no stranger to people watching him in the gym: girls checked him out, guys saw him as competition and the newbies closely monitored his form in the hopes of learning from him. Jake mostly appreciated those stares, but it was the predatory stare of one Frank Smith that made Jake’s insides squirm. The two men couldn’t be further apart. Jake was a twenty-two year old fitness influencer with his whole life ahead of him; Frank had to have forty years on him and had definitely seen better days. There was no doubt in Jake’s mind that the older man lusted after him just as much as some of the InstaBabes did, but unlike with them, the fitness influencer didn’t exactly appreciate the attention.

On that fateful day Jake had decided to cut his workout short after catching Frank staring at him one too many times. He was rearranging the pathetic lump in his shorts too - must have popped a pill to get that old thing up - and overall was just being his usual creepy self. As he stopped off of the running machine, dripping with sweat from the intense bout of cardio, Jake made sure to turn up the music blasting through his headphones so he didn’t risk hearing any of the old man’s gross grunting or groaning. Unfortunately for him, that left him unaware of Frank’s rapid pursuit of him into the locker room until it was too late and he found himself slammed face first against the hard wall of lockers.

For the first time in a long time, Jake was completely overwhelmed with terror. He clenched his ass cheeks together, anticipating the worst, especially considering he could already feel the other man’s bulge pressing against his rear. Frank’s true intentions were a little more unusual though, as he made no attempt to rip the young stud’s clothes from him, or even expose the voluptuous curves of his ass. Instead he continued to push and push against Jake’s back, creating a pressure that should have been impossible. Jake was left gasping for breath as Frank’s rotund stomach broke through the walls of reality and began to sink into him. The sensation was uncomfortable, like he had eaten far beyond his limit, and everything in the young man’s mind insisted that he fight back. Unfortunately it was too late for any sort of retaliation, as the process had drained Jake of all of his strength, leaving him as helpless as a mouse in the jaws of a cat.

The strange attack concluded after a few more seconds, with Frank’s large body having completely sunk into Jake’s flesh. The horror of the situation didn’t exactly die out there though, as Jake found himself accompanied within his own mind by an alien presence. Oh, my dear boy, Frank’s voice rang out in his head, You have no idea how long I’ve waited for this. Jake’s attempts to speak - to curse the other man out - were met with immediate failure. He no longer had control of his own voice, or even a single part of his body. He had been forced into the passenger seat while Frank occupied the driver’s spot.

While being at the mercy of the creepy old man was bad enough, Frank’s obsession with Jake’s natural scent was perhaps the most troubling thing to the younger man. In the twenty-four hours since Frank’s residency within his body had begun, the body thief hadn’t been shy about expressing his love for the masculine musk that Jake’s body radiated, nor the taste of sweat. More than once he had dropped to the floor and performed a full one-hundred push-ups just to work up a sweat so he could lick his biceps clean and then take a long whiff from his hairy pits. Jake was absolutely disgusted, but with Frank’s mind in control, his body had a noticeably positive response to the crude behaviours.

The musk hung heavy in the air around them as Frank steered Jake’s body into the gym the next day. The sexy redhead behind the desk even recoiled from the strength of the scent and more than one of the girls that Jake usually flirted with seemed disgusted by just how strong the stench was. Frank didn’t seem to care though, in fact he seemed to relish in both their responses and Jake’s own dismay. You’re all too weak to handle the pheromones of a god, Frank thought arrogantly. That was how he saw himself now he was operating the fine machinery of the young stud’s muscular physique: an adonis among men.

As if the revulsion of Jake’s fangirls wasn’t bad enough, it also wasn’t lost on the trapped stud that his body’s invasive occupant continued to turn his gaze to some of the hairy older man who didn’t seem quite so off-put by the stud’s newfound reluctance to shower. He could already tell that he wouldn’t like what Frank had planned next for them...
