"Tommyyy, have you gotten a gym membership yet?" my girlfriend nagged for the fifth time this week.
"I told you I've been busy," I lied.
"Suuure," she scoffed. "Well I'm tired of hearing your excuses, so I decided to buy you one myself. That way you can't wiggle your way out again!"
"Becky..."
"Don't 'Becky' me! Come on, I promise it won't be that bad. You'll love being fit!" She popped a hip to flaunt her toned tummy, solidifying her point.
"You know I always lose motivation...."
"That's why I signed you up for a few sessions with a personal trainer, someone who'll really kick your ass into gear!"
"That sounds... expensive."
"Don't worry about it, the sessions come free with the membership. Just think of this as your Christmas gift, okay?"
I would've preferred a PlayStation 5, but I guess that wasn't happening. Not wanting to upset my girlfriend further, I decided to acquiesce. She was being generous and it really wasn't a big ask.
"Okay, baby," I told her with a genuine smile, "I'll go to the gym."
"YAY!!"
She ran over and kissed me, then set down my running shoes and a pair of shorts. I twiddled my thumbs, unsure why she did it.
"Well, what are you waiting for? Aren't you gonna get changed? Your first session's in 20 minutes!"
"What! Today?? But it's Saturday morning, baby, you know I love hanging out."
"You've hung out enough, Tommy. You're 24 years old, it's time to man up! I'm gonna drill some good habits into you if it's the last thing I do, and I'm sure that trainer will dole out some tough love!"
Sigh, what a drag....
"Fine, fine, I'll head out." I donned the gear and pulled my girlfriend into a hug. "See you later, okay? And when you do, I'm gonna be a new man!"
I flexed my slim arms and she squeezed them teasingly.
"Have fun, babe, but not too much!"
I'm sure that won't be hard....
While driving over, I thought about the gift my girlfriend gave me and how receiving it was inevitable. She was a cardio bunny who hit the gym daily, while I stood tall and willowy, somewhere between a twink and a jock. I couldn't blame her for kindly pushing me towards the masculine end of the scale, and was determined to become the man she wanted.
Though I had a lovable face, I never understood why she dated me for two years, instead of somebody manlier. Frankly, Becky was way out of my league, but she told me she loved me often, and I believed her. I'd gotten extremely lucky with my catch and wasn't about to let her go.
When I pulled into the parking lot, I spotted a bunch of douchebag cars, and fittingly, a bunch of douchebags. While walking towards the building, I overheard one Herculean man ask another:
"Yo, Nico, you hittin' chest today?"
"Yup," 'Nico' replied proudly, "gonna try to break 300!" He took a swig of neon pink liquid from his blender bottle and pounded his chest.
"Fuck yea, dude!" the other man applauded with a bro handshake. "You're lookin' huge! It'll be no problem. Aight, catch you in there."
So, this was my new gym? One frequented by meatheads who acted like gorillas? Why couldn't Becky have signed me up for some geriatric establishment where I would've been the strongest guy?? I'm gonna look like a total wimp here!
As I went to begrudgingly open the door, it swung open from the inside before I could push.
"Ah, you must be Tommy," a soothing accent inquired.
I looked up from the floor and was greeted by a man whose size put the parking lot boys to shame. He must have stood 8 inches taller than my 6'2", with shoulders twice my width. His broad torso was covered by a black polo that would've draped over me like a gown, but fit him perfectly.
His thick thighs proved he never skipped leg day, and the forest of hair on his shins matched that fluffing out of his collar. Up top, he had a trim beard, handsome face, and mid-length hair pulled back into a bun. His features looked slightly foreign, but I couldn't place his accent.
"Uhh yeah, that's me," I replied, sticking my hand out to interlock it with his.
"Pleasure to meet you. I'm Fabio, your personal trainer."
"N-nice to meet you... Fabio," I winced as he crushed my palm.
"Come, boy, let me show you around before we get started."
Fabio put his hand on my lower back and led me away from the entrance. I was a little annoyed that he called me "boy", since he only looked 30 years old, but his size gave him permission to do what he wanted. His hand on my back was weird, too, but I chalked it up to his culture, whatever it was, being handsy.
"So, Fabio, where you from?" I asked when we arrived at the first weight rack.
"You noticed my accent, eh? I'm from Brazil, Tommy. I was born and raised there, but moved here a few years ago to coach."
"Ah, cool." So that's why he has that perfect, golden tan.
"Enough about me though, my boy, why don't you tell me about yourself. Have you set any workout goals?"
"To be honest, I'm really only here because my girlfriend signed me up. She thinks I'm a weakling, so I guess I wanna bulk up a bit. You know, bigger arms, bigger chest."
"Hmmm, I see..." he muttered, circling as he inspected my body.
He had a thoughtful hand on his chin while the other began to explore my exposed skin. He started with my biceps, totally encasing them as he took inventory. He did the same with my svelte thighs, measuring their girth, both paws barely needed to wrap around. His invasion of privacy made me extremely uncomfortable, but the heat of his palms and strength of his grasp was strangely titillating.
"Take off your shirt, Tommy, I need to see everything before I can create your personal regimen."
I complied, figuring what the hell: I'm here, my girlfriend paid, let's do this. With my shorts also removed, we stood in front of a floor-length mirror. Fabio towered behind my trim frame as he rubbed my torso up and down.
He held my slim waist and commented, "so, tiny..." then added, "but you've got a nice bubble bum!" with a friendly spank.
I blushed with emasculated shame at my lithe figure and pert behind. I wished I was bigger, but I just got toned when I worked out. The only gains I ever made were in my ass, which my girlfriend said women would die for. I always gave up eventually, but now was my chance to actually improve myself.
"So, Fabio, you think you can thicken me up?"
"Yes, my Tommy." I squirmed when he said 'my', his hands still firmly planted on my hips. "With the plan I've just crafted, you're gonna get thick in all the right places."
He gave my butt a sharp smack then let me put my clothes back on.
"Alright, Tommy, before you use the heavy weights we need to work on your foundation. That means we're gonna start with lighter lifts and higher repetitions. We're also gonna mix in some cardio, yoga, and swimming to make sure you get a holistic workout experience. That all sound okay to you, Tommy boy?"
He had his arm around my waist again as we walked. I probably should've nipped his constant touching in the bud, told him it was inappropriate, but this giant man and his gym were so overwhelming.
"Uhhh... y-yeah, sounds good..." I stumbled.
"Don't be nervous," he comforted, stopping us to look at me while he tickled my spine. "I'll be here to guide you every step of the way."
"Th-thank you, Fabio," I stuttered again.
For some reason, this beast made me feel funny -- in a way I hadn't felt before. I couldn't quite put my finger on it, but something about him made me squirm. I think maybe since he's such an Alpha it was hard for me not to feel submissive. I got along well with most guys, but around real red-blooded men I always reverted to my beta tendencies, and Fabio seemed to have me clocked.
"Okay, boy, we're gonna start with some squats. We won't use any weight at first so I can monitor your form. Here, get in front of me."
Fabio and I stood next to the squat rack staring at each other in the mirror. Again, he held me from behind.
"Squat down now, Tommy."
I lowered myself and bent at the knees, accidentally brushing my big butt against Fabio's meaty crotch. When I felt its thickness, a jolt of lighting surged up my spine. That was weird.... His strong arms pulled me closer as he eased us down together, his bulge poking into my ass the whole time.
"That's it, my boy. Knees should point out, eyes straight." I adjusted my position. "Don't arch that back so much," he chuckled with a spank, "there will be plenty of time for that later."
"Sorry, sorry..."
"That's alright, Tommy. I need to make sure your form is perfect, since you're gonna be doing thousands of these!"
Thousands?? How long was this gym membership!!
"How am I doing?" I asked after what felt like a hundred.
"Good, good," he replied, but was clearly still thinking. "Those shorts though, boy, they're too long."
"Sorry... I didn't know."
"Don't worry about it. I'll bring you a new pair tomorrow that'll be easier to move around in."
"Thanks, Fabio!"
He patted my butt as a "you're welcome". It was generous of him to give me new shorts since mine kept getting caught at the knee. Fabio was a really thoughtful trainer, and I started to get excited about the set up my girlfriend had given me. By the end of this, I was gonna be huge!
"Okay, Tommy, that's enough squatting for today. Now I'm gonna have you cool down on the Stairmaster before we stretch you out. Let's go."
