Chapter Text
Soap knew he needed to lose the few extra pounds he had packed on during his vacation. His jeans were starting to become snug, shirts sticking to his now soft belly.
He found managed to find a local personal trainer on Instagram, and decided to give him a shot. He messaged the trainer, asking if he was still taking new clients. A man, who went by the name Ghost, messaged back “Yeah, I have a free spot open on Tuesday. We can go over your goals and create a workout regimen.”
Soap clicked on the man’s profile, scrolling through his pictures.
Oh no.
He was hot as hell. How was he supposed to focus on exercising when the man who would be watching him looked like a Greek God, with six pack abs and an absolutely built body. Soap sighed, he had already accepted the appointment. He could just cancel after the first one if it was really that bad.

Soap woke up on the day of his session, nervous about what to wear. He had outgrown most of his work out clothes. He decided on a pair of not too tight gym shorts and a t shirt that showed the outline of his small beer gut a bit too well.
He walked into the small gym, which was thankfully empty. It seemed it was a private gym, Soap assumed he must be a damn good personal trainer to be able to afford his own private gym.
The hot-as-hell dude emerged from the back of the gym, shirtless and slightly sweating. He must have just finished his own workout. Soap looked at his watch, he was a bit early.
“Hi, you must be Soap. It’s nice to meet you, you can call me Ghost. Let me show you around before we get started.” Ghost greeted.
He walked Soap around, showing him the equipment. There were a plethora of weights, and dumbells, a treadmill, an elliptical, and a weight bench, with floor to ceiling mirrors covering one wall.
Ghost asked him about his goals, Soap telling him how he wants to lose the few pounds he had packed on and gain some more muscle. Ghost set up a workout regimen, Soap would come in 4 times a week, working out on a different machine each day.
Soap’s first day of exercise would begin tomorrow.
————-
Soap walked in the next day, the same outfit as the day before, ready to get started. He was excited to finally get in shape.
Ghost greeted him before saying, “I’d like to take some before photos of you, as well as take your measurements, so that we can track your progress.”
“Just stand there CLICK now shirt off please CLICK and turn to the side CLICK. Alright now that that is done let’s take your measurements.” Ghost pulled out a fabric tape measure, wrapping it around his midsection, hips, and one of his thighs, before making note of them.
“Before we get you started on your exercise today, drink this. It’s like pre-workout, it’ll give you more energy.” Ghost handed him a tall blender full of cream colored liquid, it looked very thick.
“…Are you sure this isn’t too much?” Soap asked apprehensively, it was a lot of liquid, especially if he was going to be working out right after. He didn’t know if he wanted to be running with a full sloshy belly.
“No, it’s not too much, I’ve been doing this for years, you’re body needs energy and sustenance in order to be able to exercise properly.”
Soap shrugged, taking the blender out of Ghost’s hand. He began to chug the thick liquid, it was quite sweet, but it was absolutely delicious. His other hand absent mindedly went to his belly, feeling it slightly swell out as more and more of the liquid was swallowed.
Unbeknownst to him, Ghost was watching hungrily as he saw Soap’s belly begin to expand from the thick shake. What Soap didn’t know was that what he was drinking wasn’t pre-workout, but instead a fattening weight gain shake. He felt himself grow hard, suddenly glad he was wearing loose black pants.
Soap finished the shake with burp, holding his gut with both of his hands. “Oof, that really filled me up.”
Not wanting to say something he’d regret in a moment of horny brainfog, Ghost said nothing. He simply walked over to the treadmill, waiting for Soap to follow.
“We’ll start off slow today, a 5mph jog for 20 minutes, then we’ll see how you feel and go from there.”
Soap let out a small burp, trying to stifle it behind his fist. “I don’t know man, I’ll try but I am super bloated right now.”
He got on the treadmill, turning it on and started to jog. Immediately he could feel the heavy liquid inside his belly slosh as his slow jog made his gut shake. He let out another burp, all the shaking dislodging some air bubbles.
Ghost watched from nearby, he swore he could hear the sloshes and gurgles coming from Soap’s gut from halfway across the room.
It didnt take long for Soap to start panting, weighed down from the shake he drank earlier. He somehow managed to make it all 20 minutes before nearly collapsing. Ghost took pity on him and gave him a 15 minute break before getting back to work.
“Drink this, you need to make sure you’re staying hydrated.”
Ghost handed Soap a Gatorade, which Soap gratefully accepted, suddenly very thirsty after his jog. He chugged it, his belly pressed against his shirt even more, the indentation of his belly button showing through it.
“Next up is sit ups, we’ll just see how many you can do to get a baseline.”
Soap laid on the ground, feet held by Ghost. He tried to do a sit up but found that all the liquid in his gut was making it very hard to do so. Every time he tried, his little beer belly sloshed back and forth. He only managed to do 10, before slumping back onto the ground, gut jiggling as he did so.
“Good effort Soap, one last thing before you’re done for the day. Push ups.”
That was one thing that Soap was good at, even though he had gained weight, he made sure to do a few push ups each day, a leftover habit from his time in the military.
Soap got down on all fours, his gut, though small, still hung heavily down. It was a weird feeling, gravity and the mass of liquids he had consumed earlier both making his gut feel extra heavy. He kicked his feet out and started the push ups. What he did not expect was his belly to graze the ground as he went down. Each time his belly bumping into the ground as he completed his push ups. He got to 60 before he finally tapped out.
“Alright, good job today Soap, I’ll see you tomorrow.” Thank God Ghost had an amazing poker face, he had lots of things to add to the spank bank, which he would be sure to indulge in later. He couldn’t wait to see how big Soap would become under his care.
