Summary:
TF Kinktober 2025: Day 13 - Autobot/Decepticon ll Size difference
A value of a thing is usually known only when it is lost, but in this scenario, the sole fact that these things existed was already a choice that probably wasn’t the smartest of both leaders of the Cybertronian Alliance
Yes sir/Ma'am/Temperature Play/We Shouldn't Do This/Power Bottom/You Need To Be Punished/Spreader Bar
Long post because oops I should have posted this days ago
Yes sir:
Rung would never use his authority over a prisoner against Tarn, but he'd recognize that Tarn responds primarily to commands. He'd find just talking to him would not lead to him opening up as much as he should, but he would learn how to give an intimidating tone after playing with Tarn's thoughts for awhile.
He wouldn't ever do this in a session. This would be off the books when he's sneaking into his cell. He knows he shouldn't, but everyone on the ship knows that Tarn needs all the help he can possibly get. And a few extra visits wouldn't be too strange.
He'd just be spending them doing some highly illicit and very frowned upon oral activities.
Tarn would be confined via stasis cuffs or outright immobilized on the bed slab, leaving Rung to do all of the work. He wouldn't mind, cleaning up after would feel like he was doing something nice.
We shouldn't do this:
SPEAKING OF
Rung's guilt with Tarn would be incriminating if he didn't hide in his room from the shame.
He'd dodge Ultra Magnus every time he could because he knew everyone on the ship would actually just toss him into a cell if they knew.
Tarn would not feel the same kind of guilt. He's lost, knows Megatron gave up, and depressed. His reliance on any sort of guidance would outright be unhealthy and clanking with his psychiatrist is not helping. But he lived his life as a con long enough to be fine with outright selfishness.
Rung however, would tell himself he's a terrible bot until he's either throat deep in Tarn or in the middle of nearly denting his thighs from riding.
Power Bottom:
Tarn, if he had any control, would try to be smooth and cool even with Rung bouncing on him. But he'd be far too distracted to enjoy himself. He'd care about his image, especially if he was trying to give commands or dirty talk. It goes against his image. He's untouchable, and any admittance to weakness or that he wants someone would be uncomfortable.
Rung could take submissive positions, but he'd know how to spin it to be in control.
Bent over, face pressed on the bed slab, he could figure out how to instruct and guide Tarn while speaking to his kinks. He'd ask him questions, pry, learn what gets Tarn the most excited. Rung's ability to learn people would give him everything. Tarn would physically be in control, but whimpering even while doing the work because Rung could find the right thing to say that squeezes Tarn inside just right.
Spreader Bar:
Tarn is going to be imprisoned and immobilized for a very long time.
Rung would advocate that he have the ability to be comfortable when talking, but Tarn would need to be restrained. A spreader bar that prevents transformation would be a restriction that would have Tarn restless and furious. But Rung's touch would calm him.
Their sessions would mostly have him in a chair, arms and legs far apart. It wasn't Rung's intent to be so turned on by it, but after a few sessions he brings up Tarn's sex life in a painfully unprofessional subject change.
Taking his client's virginity was never an option, but Oral shouldn't be too bad. it is
Is it not the ultimate age gap to be the first transformer ever and literally anyone under 1b years? Because Rung is OLD. Older than literal dirt. So. Tarn's close mindedness might be frustrating but Rung's used to opening people up. Even if it takes eons.
Rung may do or say something on reflex that would startle Tarn, and I think he'd be able to pull him out of Megs' grip by showing him things memory decay hadn't gotten to yet. Maybe talking about the bots who composed/wrote things Tarn likes.
Tarn would eventually see Rung as more than just a court mandated psychologist and more than anything Tarn would expect a legendary experience in the bedroom. Not that Rung would be able to provide but Tarn's an apex virgin, he doesn't know.
Threesome:
I do not think there is a single bot either would allow to join them. They both have monogamous dispositions. Tarn, purity icon and Rung, over-considerate and sacrificial.
It'd have to be an outsider's influence to bring it up and convince them both. Someone physically dominant and verbally a master at manipulating people.
Tarn is BIG. So that leaves few who exactly tower over him. And in that few, even less are bots he can withstand.
Deathsarus is a leader, and probably has close relationships with all the bots who left with him. Threesomes are likely a norm for social peace and he was an outlier even in his original continuity as a con. So he'd get a kick out of being with a blushing virgin and someone much older.
Technically a foursome, Ultra Magnus is likely the only other bot who could pull it off. Tarn would be comfortable with clean cut direction and a partner who focuses on giving more than making him do the work. While Rung would be working double to keep both of them satisfied.
Hypnotism/Bimbofication:
Rung has served others and taken on responsibility for years, trying out a way to take complete control and just get dicked would give him the most satisfyingly intense orgasms he's ever had.
Tarn's voice as is is smooth and pleasant. Hypnotizing Rung to only want pleasure through viral means would be temporary but he could learn to hack into Rung's brain module to put in some new functions. Just for a few hours.
Tarn is not a top, and would have trouble finding a way to actually please Rung as his fingers are too sharp, and he is physically too large. But he still likes the control and would be creative. Hands, mouth, making Rung ride, reverse, standing, or put on a show.
Rung would be aware he isn't himself but he's not going to fight it.
Leozack's not sure he shouldn't jsut tell the rest of Breastforce about him and Hellbat, but its rather obvious that they won't have the nicest approach. So to completely distract and win the argument, Hellbat decides a little semi-public pleasure in the shadows might be interesting. Especially when Hellbat introduces him to a different form of docking…

Sorry the link didn't paste when I thought it did!
Dirge and Jetfire are looking forward to catching up with their soaps when Sunstreaker seems to want their attention. Normally he's very overt in the manner of distraction, but this time there seems to be something different going on...
No smut although Sunstreaker's language and references meant I had to mark explicit, but a sort of sweet moment between the three

I decided to use Tranquillity x Metroplex again, but this is earlier in their relationship and sorry was in a bit of a rush for the day so couldn't figure out anything raunchy for it.
Day 29: Size Kink
Rating; Mature
Relationship: Metroplex c Tranquillity (OC)
Summary: Tranquillity is offered the chance to go for a dance with Pious Maximus, but Metroplex isn't too sure he likes the idea and ends up revealing something about himself as adorably as possible.
OC x Metroplex
Also the last two might be delayed.

Summary:
"Brainstorm, I want you to own me," Perceptor whispered, as if he was scared to say it. "Back during functionalism, even during the golden years, Microscopes like me- and other bots with alt modes that were tools- were owned. We had masters and handlers, and we listened to orders. I trust you so much, I actually want you to own me, and I'm not disgusted by the thought. I want to have your sparklings and show people that I belong to you."

Summary:
Perceptor spent a lot of his time in recharge, body focusing on retaining energy and building the Sparkling's protoform. He couldn't frag Perceptor; it would wake him up and cause them both to lose sleep, causing both a grumpy Perceptor and Brainstorm. An idea sprang into Brainstorm's barely awake processor.
He had a spare hand that wasn't wrapped up in holding Perceptor close; it was resting on his stomach and completely free

The door to her habsuite locked, the next several joors to herself, Sweeper knew exactly what she was going to do. Digging through her things, she pulled out her vibrator. An expensive thing. High quality material, 10 different settings and a suction function. Exactly what she planned to use.
Sitting on her berth, Sweeper spread her stabilizers and opened her modesty panels. Her valve hadn't started lubricating yet but she'd be well on her way soon enough. Turning the toy to its lowest setting, she pressed it to her anterior node and let out a sigh.
It felt good, her frame relaxed and her hip pressed forward to meet the stimulation. It wasn’t enough though, she needed something to think about. Picture something- or rather someone and what she’d want them to do to her, then feel guilty later.
But who should she think about?
There was Camouflage, the shapeshifting spy. They were a mystery to everyone, but everyone knew they were a big flirt. Some even call them a whore that faced with any one that sparked their fancy. Sweeper was always too nervous to approach them, but she did wonder if they would have a go with her. What would they do?
“Such a naughty girl…” They purred as they ran their digits over her frame, a knee pressed against her array. “Want me to play with your pretty valve?”
“Y-Yes, please… I'll be good.” She'd never interfaced with another bot, but she knew she could behave for them. Let them spread her stabilizers wider and trail their digits to her node. Their sharp ruby optics trailed over her and they licked their derma.
Sweeper turned the toy up a notch. This was a good start, but wasn't enough to get her to overload. Who else could she fantasize about?
Her mind turns toward Wheeler, a head strong mechanic with a hot temper but a soft spark. She took such great care of her human family. Sweeper would love to be taken care of the same way.
She glanced up at Sweeper from between her thighs, glossa lapping strips over her soaked valve. “You taste so good, Sweeps. Does it feel good?” Wheeler swirled her glossa over her node.
“A-ah! Yes! Thank you!” Her stabilizers trembled and she fought to keep her servos at her sides. Wheeler had told her to stay still and let her do all the work.
She wrapped her derma around her sensitive node and sucked on it.
Sweeper's back arched as she activated the suctioning function. Oh yes, she was really getting going now. Sliding two digits into her valve, she began to pump them in and out as her next fantasy began to unfold.
Gleam, an adorable no nonsense mini bot. Quiet and strict with nearly every bot she knows. Sweeper would be helpless under her harsh reprimands.
“I told you to stop squirming, or do you want me to restart again?” Gleam tugged on a wire a bit more roughly than necessary, causing Sweeper to cry out.
“I-I’m sorry! I'm trying to stay still!” They'd been at this for hours and Sweeper had lost count of how many overloads she'd been denied. Gleam organizing and reorganizing her wires as she failed to keep still. It was such sweet torture.
Sweeper turned the toy up even higher. She was so close. Her overload was right there. She just needed one final push.
“How pathetic.” Megatron, the fearsome warlord that could crush a bot like her with a single servo. And she would have no choice but to thank him for it.
He pressed her stabilizers up against her chassis, an iron grip on her thighs tightened as his giant spike rubbed against her valve. “Already this soaked from just this? Begging for my spike like a needy sharewear.”
“Lord Megatron- ah!” Sweeper's begging was cut off as he began to push his spike into her.
“Shareware doesn't need to speak. If that's how you choose to act then that's how I'm going to treat you.”
Sweeper's fantasy came to an abrupt end as her overload hit. Her back arched off the berth, moaning loudly as lubricant sprayed from her valve. She trembled and whined as she let the toy torment her oversensitive node for a few moments longer before finally shutting it off and falling limp on the berth. The guilt for her fantasies was sure to hit later but for now she was satisfied.
