Bumblebee was blushing hard at the bright red numbers shining back at him from Ratchet’s new and improved scale. The scale didn’t lie—especially not when it had been fitted and formatted to bear the weight of a mech growing as big and fat as he was—but the sight of those telling digits climbing higher and higher with every check-up and visit he came in for was enough to have him wanting to hide his face in his servos and never show himself again.

It was one check-up after another lately, and as the numbers on the scale climbed, so did Ratchet’s interest in his wellbeing and his teasings at Bumblebee’s reluctance to look. He had been coming in consistently for weeks by now, and he had been gaining sporadically for months. It was the first broken scale showing that dreaded ERROR code that had first gotten Ratchet’s attention, and now it was the big, round, pudgy belly poking out between Bumblebee’s poorly fitted armor that kept him bringing Bumblebee back in for more.

The weight gain wasn’t such a bad thing in small increments. Every Autobot went through fluctuations of gaining and losing as their energon stores rose and fell. It was just the way of things. Bumblebee had been through it plenty himself, and the brief visits through Ratchet’s medibay to keep track of his vitals and put marks down on his progress compared to the rest of the faction was nothing.

He was never ashamed to have his weight tracked. He had never minded seeing the numbers on the scale go up and down, either. It was just a mess of hauling his fat aft into the medibay one day after another now that got to him, and it was the way Ratchet stood with his servos propped on his hips and that faint little smile tugging at his lips as he watched Bumblebee waddle his way over to the heavy machinery in the back of the medibay.

Something was up with him, and he knew it. Something was going on, but he couldn’t put his finger on it. Something was making him gain… and whatever was causing him to gain was causing him to come back here one day after another to face Ratchet’s cheeky smile and blush helplessly under the barrage of gentle chastising and lighthearted teases.

Bumblebee hadn’t the slightest clue what was going on with him, but one thing was for certain, even if he didn’t like to admit it: going to Ratchet’s for another followup every other day to see the weight increase and track his problem was the best solution for it. He couldn’t get to the bottom of it on his own, and that much was for certain. He just had to suck it up for another day, waddle his way across the medibay as Ratchet watched him with an increasingly raised brow, and try not to sputter or blush too hard when Ratchet began asking him the same questions worded in those embarrassing ways.

The hardy medical table groaned in protest as Bumblebee braced himself against its edge and heaved. He scrambled his way up on top with kicking pedes and pitiful grunts, and once he was on top, he settled against the center with his servos folded over his fat belly and his knees bent at the joint. He could hear the scale’s numbers ticking as Ratchet turned to watch, and his faceplates grew hot in anticipation of the result of his latest gains.

The scale gave a joyful ding as the numbers stopped climbing, and Bumblebee anxiously cleared his throat and twiddled his thumbs while Ratchet scribbled down his findings into a datapad. He turned a moment later, revealing the latest progress of Bumblebee’s fattening frame.

The numbers were high. They were definitely higher than before. It had to have been the most he had ever weighed, Bumblebee was sure of it. He squirmed against the medical table as Ratchet tapped his chin and set his datapad aside, his tummy fluttering and his face hot with shame.

“Well, that’s a shocker,” Ratchet said as he stared at the scale. “Another big spike in your gaining, and it’s only been… what, three days since I last saw you in here?”

Bumblebee couldn’t help but laugh as he nervously fidgeted in place.

“Yeah,” he said, “what a surprise, huh?”

Ratchet turned back to his with a raised brow. “I’ll say. What have you been doing, packing extra rations under your plating or something?”

Bumblebee was blushing all the more as Ratchet moved in. The old doctor beckoned for him to relax with a vague wave of his servo, and he pried Bumblebee’s sweaty paws away from his pudgy belly a moment later. The number on the scale was always a shocking sight, but with the fat rolls building on his belly and the chubby mesh cropping up all over his frame, it wasn’t hard to see where the problem lie.

“Primus, Bee, you’re chubbier than a newly formed sparkling right out of Cybertron’s core!” Ratchet said as he poked the tip of his pen into the side of Bumblebee’s belly. “I haven’t been keeping track on the width of your waistline, but seeing how much you’ve gained overnight, I’m starting to think I should!”

The physical exam was always the worst part of Bumblebee’s visits for check-ins on his weight. No matter how hard he tried, he just couldn’t seem to help himself from stammering at Ratchet’s playful jabs or blushing under his poking and prodding. It was just a medical examination, of course, and he knew it was nothing to get flustered over, but slag, did it get his tummy churning and his spark pounding hard in his chest.

Bumblebee whimpered as Ratchet brushed his fingers across the curves of his belly rolls, and he giggled helplessly and nervously as Ratchet pinched at his folds. His spark was racing like wild, just as it always did when this particular step of the check-up had to happen, but he tried his very best to sit still, stay put, and let Ratchet work. It was hard, though, especially when Ratchet seemed to draw out their appointments and tease him a little more with every pound he gained.

When Ratchet had finally finished playing with the fat on his belly and teasing Bumblebee for the whole extra fifty or more pounds he had gained (because who was really counting anymore, when he had moved up to needing to use the scale made for Optimus?), Bumblebee was hot all over and desperate to be finished. He squirmed as Ratchet patted his belly, and he sat frozen on the table for a moment as Ratchet turned to document his further findings.

“You’re free to go,” Ratchet eventually said, his optics gleaming and his smile amused. “Unless you’d like me to bring out the measuring tapes and start marking down extra progress, too.”

Part of Bumblebee almost wanted to agree to the offer. Ratchet was teasing him again, obviously, but the idea sounded tempting.

“Oh, no, no,” he eventually managed to stammer, his cheeks hot and his frame hotter as he scooted to the edge of the table. “Sorry, I’ll be out of here in a second. I was just, uh…”

Processing the weight gain? Thinking about what could have been causing it? Wondering what might happen if he dared to linger a little bit longer?

Ratchet seemed to know the answer without Bumblebee even telling him. He clicked his tongue and shrugged.

“Well, the offer still stands,” he said between snickers as he watched Bumblebee tumble off of the table and waddle for the door. “Just watch that scale, Bee. If you get too big for this one, I really won’t have any choice but to measure you up the old fashioned way.”

“Right, right,” Bumblebee replied with another nervous laugh and a servo scratching the back of his helm. He paused in the doorway, hesitant to leave but desperate to hide his growing embarrassment. “So, uh…”

“Tomorrow,” Ratchet said. His back was still turned as he cleared the scale and organized his tools. “I’d like to see just how much change occurs within a given day. Who knows… maybe we’ll finally crack this gaining of yours.”

Bumblebee didn’t respond as he stepped outside and scurried down the hall. Tomorrow it is, then. He could hardly wait.

Ratchet was probably right, he bet. A day in between would be plenty of extra data to determine just how much he gained… and when he gained him. A small part of him pestered not to go, however, and begged for him to miss the direct followup just as he had several times before already. He could come in a day late, complain about the weight, and have Ratchet check him over while he teased Bumblebee for blushing and poked at his big, growing belly.

He shouldn’t. He really, really shouldn’t… but he would. He did before, and he’d do it again. Nothing beat the teasing and taunting and the gentle jabs at the flab on his middle. He was already growing used to these check-ins as is, and he didn’t want to stop them now.

There was still the issue of where his weight gain was coming from and why it was happening to solve, but the way Bumblebee saw it, that could be placed on the back burner for now. He had plenty of room to grow yet, anyway, and he had plenty more data for Ratchet to collect.

after weeks of sneaking around and seeing far more of Starscream than he ever thought he would he finds out that out of all the Decepticons on earth the only one with a knot is Megatron the least accessible of all potential berth partners

but he's determined

more plans and weeks more scouting later and he finally hooks him

Bumblebee manages to get Megatron alone and they get into a scuffle but the whole time Bee is stringing him along turning his body in just the right ways giving his little door wings a little flap here and there just enough to get Megatron's attention

it isn't long before Megatron catches on to his intentions and gives him exactly what he wants taunting him the whole time for being such an easy target letting the enemy breed him like cattle right out in the open and for a moment he teases him saying that he shouldn't knot such a disobedient thing like him since the last thing he'd want is to be caught locked to the leader of the Decepticons but Bee just wraps his legs around Megatron's hips and pulls him in deeper so he has no other choice but to knot him when he overloads

technically he could have pulled out without much difficulty but it was worth it to hear that cute buzzing raise in pitch until his broken vocalizer clicked his cute spike splattering the both of them with his overload his valve lips stretched wide around the biggest knot he'd likely ever take
