It took him only a few minutes to devour everyone in the gym. When he - a beautiful boy no taller than 5 feet even - entered, no one took him for an apex predator... but he quickly proved otherwise, swallowing down hunks three times his size with ease, while remaining quick enough on his feet to cut off any escape. Only once he secured everyone in his stomach did he slow down, waddling over to the nearest bench. Two dozen people - who dedicated themselves to honing their bodies - were helpless inside of him. This was how he packed protein~
Oliver loved hopping between gyms for bulking, it was just too easy. When the lean little thing at the front desk stopped him to tell him that the gym was for preds, he made quick work of swallowing her down. Maybe she would've thought twice about her assumption if she saw the hungry glean in his eyes, he thought, admiring himself in a mirror, it must be time to trim his bangs again.
There were two entrances to the weight room, one through the locker room and one main door. With the front desk's keys in hand he had little issue locking the main door from the outside and heading in through the locker room. Under his baggy sweater his first course wiggled around but was hidden enough to go unnoticed.
Of course, because some people only go to the gym to socialize, a pair of idiots approached him within a minute of him entering the room. The larger one attempted to intimidate Oliver and the smaller one tried flirting. So noisy...
The larger one was mostly down his throat before he or his friend realized what was happening. A few hard gulps were all it took to finish him off, and as his body landing in the gut audibly sloshed, the smaller one tripped over his own two feet and was unceremoniously pulled in feet first.
Between his panicked yelp as he was quickly swallowed and the whine of Oliver's belly, the sounds of gym noise came to a halt.
"Hey! We don't allow predation in the gym, this is a safe space and--" The barking of the gym rat who approached was abruptly cut off by his head being forced into Oliver's maw.
The short pred pulled the rat in by his shirt, swallowing hard until he was trapped with the other three.
"Huurrrrrp!" Letting out some of the trapped air, Oliver felt the angry stirring of his occupants and grinned. Quickly grabbing and swallowing the three on the treadmills that had earbuds in and were completely oblivious, he followed after the rest who had made for the door, and were struggling to pry it open.
Using his belly as a blockade, Oliver sandwiched the hulking men against the door and took great pleasure in gulping them down one after the next. Most of them tried fighting him off once they realized the doors were locked, which only put them within arms reach of him. Pinned under or against his writhing belly, they had no hope of escaping their fate, but he commended their efforts. Weaklings were no fun at all to eat, the strong well toned idiots who relied on their stature struggled much more against the confines of his body. None of the fools had noticed his strong arms under his sweater, assuming that the shorty in baggy clothes couldn't possibly make a meal of anyone.
Pulling all that mass over to the nearest bench was a workout in itself, but Oliver relished their kicking and pressing against his flesh, belching up a pair of earbuds, he knew he wouldn't be able to leave for an hour at least. The quiet gym and lean pre workout snack were perfect for getting some weight lifting done.
"Finally," he sighed, listening to his stomach gurgle around all the hunks, "Relative peace and quiet."
