Hello, I’m Matt. I love big dudes that are dumb as fuck. For some reason, they give me the impression that the more muscular they are, the dumber they are, and the more I should use them as a tool for producing pleasure.
That’s why I paid for this new personal trainer, for a 3 times a week program. I already saw from his Instagram that he’s completely dumb, posting photos where only his underwear is on, not knowing that thousands of people were jerking up on them. Big poor kid. Nice but so dumb.
At the meeting time, I went to this building where he rents a little studio with the basic equipment, some weights, and maybe 2 or 3 machines. For me it was enough, I didn’t come to work out anyway…
I knock on the door. The door is opened, and this young, muscular trainer, is standing right in front of me, with a dumb smile on his face.
“Hey, What up ?? I’m Jake”, raising a solid arm, with the roundest bicep curl you’d ever seen.
“Hi, I’m good, you?”
“I’m great” he answers. - “So, what do you want to start with?”
At this point, I could easily get distracted and forget my plan. His body was a dream. He wasn’t one of the beefy guys who look more like a ball, instead, he was tall, and very very firm. Like he for sure was way bigger than me, with his wide shoulders and lats, but his muscle fibers were visible in every movement, his thigh was just a thigh muscle - no fat on it, not even a gram, hairless, a big thick vain moves through his arm, and the big curly bicep I mentioned before, popping like a ballon every time he lifts the tiniest thing.
But I don’t forget I have bigger plans for him.
“So Jake, I thought of starting with working on the glutes muscles”.
“Glutes muscles?? Why didn’t you tell me before, it’s my favorite exercise - and the BEST part of my body”.
“I bet it’s not that good, plus, I will beat you easily after one or two weeks of lifting”.
“Oh, are you so sure? Wait till you see it before you make such statements”, and at that moment he took off his pants, just to show me a pair of buttocks covered by his underwear, rounded as two peaches, firm as iron, and clenching forcefully to the thin underwear fabric.
“Well, I must admit, you have a great butt, maybe the best part of your sculpted body”. I wasn’t exaggerating, all I wanted was to destroy the two rude rounded cheeks, covered by thin underwear, not interrupting this beautiful view.
“How can I achieve such a firm glutes myself?”
“Well, not everyone has the genetics for it, but if you want to make progress, you can touch them a little bit, and if you like it, I can build a plan suitable especially for glutes”.
I couldn’t believe how lucky I was, not only did I cause him to stand in front of me almost naked, but he also suggesting me to touch his butt?
“Let’s do it” - I answer, getting closer to his curly, peachy, enticing buttocks. I send my hand to grab this miserable boy's muscular right buttock, and…
I fail. It’s TOO firm.
Oh fuck - I couldn’t believe how hard one’s butt can become with that amount of muscle and that little amount of fat. What the fuck?
“Hey Jake I tried to grab it but it’s too hard”
“Sorry buddy! I know, I have absolutely no fat, that’s a shame. It’s not intended, just genetics. I’m pretty embarrassed about it. Do you still think my butt looks good tho?”
“That I can only tell after you take your underwear off”. I reply
“You’re right - I will take this thing off” and one second later all I can see are two perfectly shaped buttocks, with a deep dump in each side of them.
“Let me try to grab your butt again” - and with all my might I grab his right cheek. I succeed! It feels good, it feels overwhelmingly good, his butt is all muscle so it’s HEAVY, but it’s relaxed so I can grab it and feel it’s changing its shape under my hand, firm, yet finally surrender to my will. I continue pinching it, to the level I’m sure it starts hurting Jake.
The only thing I want to do is take a bite in these firm, rude, independent cheeks, staring at me like they’re allowed to.
“Hey Jake, your butt is feeling great and it does look great, you have nothing to be worried about”
“Oh I’m so relieved, thank you so much Matt, you know, you are the best!”, he said, smiling. He’s so dumb, so naive.
“Nah, it’s ok. Just here to calm down a new friend. But I need to take a big bite in your two globes behind you”
“WHAT??”
“Jake, your butt is just calling me. The shape of it, the firmness, are you sure It’s not made of iron”.
“Haha, it is really firm I know, but isn’t it kinda gross? Do you want to taste my butt?
“I know, it’s kind of gross but If I want to grow my glutes, I should see how firm glutes feel like. So yeah, I will overcome this and dive into your butt. The gains are worth it!”
“Yeah, you’re right. If you want to have firm glutes you must know what a firm butt really feels like, and no one has a firmer butt than I do, I can tell. Take it, you can do whatever you want to it, it’s all yours”. And in this statement, Jake is standing in front of me, as I sit on the floor and his two buttocks are just in front of my face, subject to me.
I got closer, and in a fast move I stuck my face inside the two hills, the heavy, firm, hard round muscles, that enclosed me, I sniffed his hole while his two globes were closing on me from left and right, fighting to breathe, as his two radiating globes were so hard I struggled to get out. From this moment on, his butt became my private playground. I pinched it from every angle, ate it, flipping it so I could see it bouncing, making him close his glutes on my face, (knowing the firm muscles wouldn’t let me get out so quickly). Poor Jake’s ass became completely red. As a good trainer, he knew he would do anything to make me progress, even if it’s involving assaulting his poor butt.
After I finally finished playing and squashing Jake’s used butt muscles, he said:
“Hey Matt, we’re still having 15 minutes, you want to start working out your glutes? Starting with squat?”
“No, Jake. You made an effort for me today, I see how red your butt became, you worked hard and bore this. I want to compensate you for it”
“Matt, you’re the best client I had, you helped me feel secure with my body and you even sniffed my ass to progress, it’s the best sacrifice a trainee can do!
“Yeah but Jake, you sweated and burned calories, and it’s not that you have big reserves anyway, don’t you want to get back the protein intake you deserve? Just for 15 minutes, let me do something back to you”
“Yes I do want to get back some calories, you saw how I need to be strict with the diet”
“Yes. So let me give you a protein intake, and the best protein is the human protein, the sperm. Please, let me give it to you, you need it.
“What do I need to do?”
“Spread your used buttocks open”
“Well I never did it before - but I won’t say no for a big intake of protein. My butt is open to you!”
His two dumped, peachy, hard as-steel cheeks were spreading wide open, while he bent in a submissive manner as I commanded, willing to get penetrated.
I was already hard, my thick dick about to tear this incredibly tight hole apart.
I’m getting closer to him, his tiny hole is barely seen.
“AHHHHH” I hear him screaming.
His hole could not bear the pain of my fat penis pushing inside, and it was just the tip. It was so firm, that I felt I was tearing him apart. Slowly, I pushed inch after an inch, and eventually, my penis was surrounded by his firm interior muscles. He didn’t seem to enjoy it, but oh, I did so much. I drove him like a used muscle slave. And just looking at his open ass, looking towards me, his lats spread in submission, knowing that this is the situation he must undergo if he wants to get his protein intake. He went through this bravely, waiting for my sperm to fill him inside. After no more than 30 seconds, I put my two hands on the destroyed red cheeks, and hear myself scream
“AHHHHHH”
As I release waves, no, rivers of sperm into poor Jake’s hole. I wonder if he got enough space in his belly to store that amount of cum, but I guess he did., his abs started to bloat as his whole belly tried to contain the crazy amount of cum I filled him. Not one drop of it was leaking out. As I took my penis out, his tiny pink hole closed, keeping my sperm inside, and his two cheeks bounced gently as a thank-you gesture. I stood up and we started to dress.
Dumb Jake stood up and said - “Matt I’m so glad you chose me as your trainer, you even gave me your protein! I’m grateful. I should thank you! Let’s continue the good progress next time”
as I see him walking away, his abs still bloated from my sperm and a big smile on his face.
And I know this is not the last time I will take care of him…
