"Well, that's another gym gone," I said to myself, as the pool of thick white seed spread across the floor, more and more half-melted bones becoming visible as it expanded. "And this was a good one, too..."

It's not my fault if people keep disappearing from the gyms I work out at and they're forced to close down as a result. Well, alright, it's mostly my fault. Actually, it's almost entirely my fault. But this time I did my best! The place was in the perfect location, five minutes from my apartment and right next to a metro station. It had top of the line equipment, really nice showers, friendly staff (it used to be "mostly friendly staff," but that changed after my first visit), and they were open 24/7. Pretty much the perfect gym.
The turnover rate for establishments in my city is dangerously high, and I take pride in saying I'm one of its main causes. Restaurants, shops, bars, hotels, and of course, gyms, often close down due to a lack of either customers, staff, or owners. From time to time, all three combined.

I tend to run even the places I like out of business, but I was doing my best to preserve this specific gym. At one point the owners pleaded with me, begging me to stop eating their customers, and I promised I would do my best to keep them afloat. Sure, I still grab a few snacks here and there, but compared to earlier, deaths and disappearances in the area have gone down by over 95%. That's some self-control, am I right?

Unfortunately, I wasn't the only one around with these specific eating habits. Turns out Nooniya, a local shark, also used to enjoy some heavy post-workout snacks. He got his hip a few weeks after I made my promise to the owners, so he must've thought I was just any other lizard there, a potential victim to his hunger.
He was sorely mistaken.

The guy just loved to show off, and honestly, with a body like his, I didn't blame him. He always wore a pair of shorts that looked like they were constantly about to burst, and his t-shirt was so tight that he might as well have been working out bare-chested. I have to it, it wasn't a bad sight at all. But there was definitely more about him.
After checking him out for a while, it became clear that he shared the same predatory appetites as myself. I noticed how he always had a different date after his workouts, and from his locker room exhibitionism it was clear where all those guys inevitably ended up. He was tall, muscular, and extremely well endowed. At least, by regular people's standards. You could hear his big heavy nuts growling from two rooms away, they weren't just for show. Not as productive as mine, but definitely close. The strong musk that was always present in the men's showers after he'd leave for the day was proof of that.

The day it finally happened, I was just drying up in the locker room. After an hour or so of training, I tend to build up so much precum that I have to spend around ten minutes in the shower draining most of it out; I was finally enjoying the feeling of a lighter sack to carry around. I was just about to get my clothes when I bumped into Nooniya. He wasn't even bothering to wear a towel, exposing his larger-than-life member to anyone who dared to look, and the cries coming from his squirming nuts told me exactly where the newest personal trainer had ended up. He had a hungry look in his eyes, and as he placed himself between me and my locker, his cock started throbbing, reaching up towards my face.
"I forgot my post-workout snack at home, but it looks like I've found a replacement," he said smugly, before adding, "sucks to be you, lizard boy!"
That was it. I would've tolerated him before. Hell, I enjoyed watching him work out. But if he was thinking I'd end up in his balls, well, he just had no idea what was about to happen.

It didn't take long. After I removed my towel, it was way too easy to suck his right hand down my member. And after that, it was just a matter of waiting. At first he was angry, struggling, he thought that an apex predator like him would have no trouble freeing himself from the grip of a small lizard. But with every attempt to pull himself out, my cock pulled stronger, and in just a couple of minutes he was struggling from inside my sack, furiously trying to find a way out.
But there was no way out, except as a hot pile of creamy lizard jizz and whatever half-melted bones managed to survive the ordeal. He was so cute, throwing insults at me while doing his best to avoid spreading my caustic cum all over his body. He even thought he could get revenge on me, telling me that he'd "show me how its done."
I couldn't resist taunting him back, clenching my fat nuts tightly around him until I heard his bones crunch, his ligaments snap, his flesh slowly and painfully melt. And just like that, he was done.

He never stood a chance. I felt some relief as Nooniya's remains slowly leaked out on the floor, I wouldn't have to deal with that pathetic shark eating all my snacks anymore. But then it hit me. Just before I slurped him down, he was busy digesting the last personal trainer that worked for the gym. And the previous day I had eaten the last receptionist. There was no way the gym could stay afloat with those losses.
It was going to be an awkward talk with the manager.
