Ultra Magnus and Predaking.... fighting being like a mating and claiming ritual for predacons. Predaking managing to overpower Magnus in a fight, roaring and pinning him to the ground on his front

When Magnus feels those long sharp talons dig between the armour plates on his back, he's sure that's it for him. He has lost. He's incapacitated. He knows backup isn't coming soon enough

He's expecting deactivation, or at least pain- He's not expecting to feel his legs kicked apart and claws on his modesty panels. Those panels are easily pried off with sharp claws

Magnus doesn't quite have the time to process what's happening- he kicks on instinct, attempting to struggle, only to hear Predaking growl and dig those claws further into his plating. But what makes him freeze is when he feels the press against his now exposed array. It's not even the pressure of the dragons spike that freaks him out, it's the fact that it makes him aware that he's already wet

Was it the fight?? The grappling?? The hot fuel pumping through his lines?

He feels the thick shaft rub against the entrance to his embarrassingly slick valve. The angry growl softens into a pleased purr. But the purr is closer, faceplate now close enough to the back of Magnus' helm that he can feel the hot air escaping the others intake

He has just enough time to realise the other is nuzzling against his neck cables before he screams, his valve suddenly split open by the massive spike. Reflexively, he tenses, his valve clenching, drawing another purr from Predaking. In his horror, he realises the other is still pushing in further. Magnus can only cry out and attempt to kick again as his already full valve is stretched impossibly wide

The spike slides further and further into him, forcing his callipers to click and strain. It burns and yet Magnus embarrassingly just leaks more lubricant. He tries his best to struggle and yell, but when that spike sinks all the way in and bumps against the seal to his gestation tank, his cries are clearly no longer of pain

He's so full. If he could put a servo on his torso he would probably feel Predaking's spike through his plating. Magnus doesn't want to think about it. It's not sending a hot shower down his spinal struts

When the spike begins to slide out of him, Magnus almost lets out a sigh of relief- before it slams back into him. He gasps, his whole frame jerking foward with the force. The thick shaft slides in and pushes against all his internals. Another thrust in and Magnus is suddenly acutely aware that it brushes past his waste tank

His audials are filled with the pleased growls and pants from Predaking as he's roughly pounded into. Every stroke makes Magnus' valve attempt to clench, as impossible as that is, and drool even more slick all over Predaking's spike and onto the ground. He's definitely not gasping and shuddering in pleasure as the spike slams into all his sensitive nodes, pushing against his waste tank, making his waste port twitch and clench

When Predaking suddenly roars, he thrusts in with even more force, slamming into Magnus' ceiling node. Magnus just knows he's screaming. He's yelling in pleasure and feeling fuller than he's ever been. Is- is the spike getting even bigger? Predaking's spike pulses inside him and starts to swell at the base. The pressure is too much. Magnus is screaming again as his overload crashes over him, his valve calipers cycling and attempting to clench around the spike

He's so full. He's so so full and all the clenching and tensing and he's vaguely aware there's so much pressure on his waste tank that his waste port finally fails. He's moaning and twitching on Predaking's spike, waste fluids squirting and spraying all over. He can feel another pleased rumble through his back plates as Predaking ruts his knotted spike further into Magnus' sopping wet valve

As the overload finally begins to fade and Magnus flops onto the ground, he's acutely aware that he's still stupidly full. He can only groan as he feels the knot shift inside him

But then the knot pulses again and Magnus moans. It swells again. Magnus is already such a mess it just pushes more piss out of him, leaking out onto the ground as he feels the spike stretch him further

But it doesn't just swell. The mass moves. It seems to shift further into him. Magnus only realises too late what it is when he feels even more force against the seal of his gestation tank. There's nothing he can do. He can't pull away. He's locked in place. He can only keen as the egg slips out the tip of Predaking's spike and forces its way past the seal to his forge

And they keep coming. More eggs push their way into his frame, each one making him shudder and leak more fluids all over. By the time the knot goes down and the spike is finally withdrawn from his frame, Magnus is a shaking and whimpering mess, his valve loose and gaping, laying in a pool of his own lubricant, transfluid, and waste fluid

Oh and Predaking is pleased. He leans down and trails his long tongue over the ruined valve, licking up the messy fluids, running it over Magnus' swollen and oversensitive node. That tongue dives into the valve, helping clean him up a little, and Magnus can only cry out as he overloads again, spurting even more fluids out of his leaky holes

god yes that's so fucking hot. knot and piss into that prim and proper bot Predaking!! go on... egg him

Based on that thing where swerve fills his waste tank with engex.......

Roddy would immediately be jealous. He would love the attention. He will find a way to empty a whole bottle of engex into his waste tank and offer to let other bots drink it straight out of him

But uhhhhh there's a few problems.

Turns out no one wants to drink from the captain's gross valve. He's kinda knows for his filthy piss antics I'm not sure if they wanna deal with that. Also it seems he really didn't research this at all. He's filled his tanks with really strong engex. And with it being inside him, it starts to burn

With no one emptying his waste tank, Rodimus is left with a really really warm and then later burning waste tank. He has to give up and call it a day by the end of the night when he can't take it anymore

I need him squatting and pissing the engex back out but it burns as it passes through his waste port and he hisses and whimpers. He wants it out as quick as possible but also it Hurts. It ends up coming out is quick spurts as he tries to push it out quickly, but then immediately regrets it and tenses and stops the stream from the pain, before immediately trying again. I want him crying and dribbling hot hot down his thighs as he lets it leak out of his burning piss hole

hgnh no one wants Rodimus’ nasty pussy... that thing is so, so gross!! who knows where it’s been!! he has to deal with it all by himself, pissing out engex through his puffy red irritated pee-hole, crying in the washracks the entire time. it hurts to sit for days afterwards..

this blog is all for you soldier o7

[unsanitarystation]

I’ve been thinking about this ask (https://www.tumblr.com/unsanitarystation/743749088612335616/cw-for-twincest-here-but-heres-the-drabble-friend?source=share) for some time now.

The idea of mech A being unable to use a toilet because they promised mech B that they will only use their mouth to void into is too hot to ignore. So, I thought: ‘What would happen if someone had COMPLETE control, not just a promise, over a mech’s waste tank?’ This ask is mostly about piss kink. All of this is around 3k words long.

All Cybertronians pee from their valves and all their toilets are squat toilets. Sentinel becomes the Primes’ slave by accident and then is saved by Starscream after all of them die.

Before Sentinel from TFone steals Megatronus’ T-cog he’s much smaller, shorter and less bulky than his movie version. Little Sentinel’s body creates addictive pee and the Primes find out about it by accident. At first, they order him to stop using a toilet and only void into a big cube while one of them watches. Sentinel finds these orders bizarre and disgusting. Being watched while peeing is embarrassing and humiliating which is why Sentinel doesn’t want to follow them and uses a toilet when the Primes aren’t watching. The Primes inevitably find out about Sentinel sneaking in to void into a toilet and decide to do something drastic about it. Sentinel doesn’t know yet why the Primes want to collect his waste fluid.

They put a special remotely controlled catheter into Sentinel’s urethra to completely control when he voids and how quickly he can void. The catheter also collects the information when and how much he voids. Sentinel is a smaller mech and his bladder isn’t very big, which is a problem because all 13 of the Primes like to drink his waste fluid and his body doesn’t produce a lot of it. The Primes keep tabs on each other to make sure everyone drinks an equal amount.

It takes some time for a Prime to order Sentinel to show them his valve but instead of telling him to void into a cube they put him on their desk and kneel before his spread legs. They quickly start licking his valve and sucking his external node. It happens so fast Sentinel doesn’t have time to react. He’s clutching their head and moaning without abandon. He quickly overloads and the Primes keeps on pleasuring him. What Sentinel didn’t notice was that the Prime forced him to slowly dribble piss when they were licking his valve. It takes few more times to notice what the Primes are doing because not all of them care to pleasure his valve while drinking from him. Sentinel is disgusted that they are drinking his waste fluid.

Sentinel’s valve is too small to be spiked by any of the Primes, so they sometimes sit him on their pressurized spikes and make him rub his external node over them. Sentinel has a surprisingly big spike for his frame and the Primes make sure to use it. They sometimes order him to lick their valves or spike them. The Primes always make sure that Sentinel licks them clean after he’s done servicing them. Licking his own transfluid from their valves isn’t pleasant because it doesn’t taste very good but Sentinel is used to it. That’s why he prefers to lick their valves and not spike them. He has spent a lot of his time kneeling under their desks, sucking on their external nodes.

The Primes keep his waste tank nearly full all the time after they start drinking his waste fluid from the source and not a cube. It’s horrible to exist with a constant need to void and Sentinel is hardly ever permitted to completely empty his waste tank. Sentinel is too busy thinking about his bladder to betray the Primes in this AU. His small valve gets so wet when he’s bursting it’s embarrassing to open his modestly panels. No matter how many times he begs the Primes to let him pee, they never do.

Sentinel sometimes goes to a bathroom to use a toilet without the Primes’ knowledge and tries to void to no avail. He squats over the toilet and touches his wet valve and the protruding part of the catheter but nothing ever comes out. He’s crying and begging for it to just let go because he’s so uncomfortably full and needs to pee. Sentinel starts to walk a little funny when he’s nearing his limit. The Primes successfully break his mind.

One time, Sentinel starts to starve himself to produce less waste fluid. The Primes quickly find out about his little scheme and punish Sentinel. At first, they try to force-feed him energon which ends with Sentinel spitting most of it out, so they are forced to find a different way before using a feeding tube on him as the last resort. They try to breastfeed him next. The Primes tell Sentinel about the consequences of biting their nipples before forcing Sentinel into taking one of their nozzles into his mouth. He spends literal hours sitting on a Prime’s lap with a nozzle stuck in his mouth before giving up and experimentally suckling on it. The sparkling grade energon tastes so good Sentinel can’t stop himself from drinking it until his fuel tank is full. Being fed breastmilk leaves him a little sleepy and much more compliant which the Primes love. After enough time being fed exclusively breastmilk Sentinel stops being able to drink normal energon. Another thing that shackles him to the Primes.

Sentinel loves the rare days when the Primes let him completely drain his waste tank into a huge cube because all 13 of them want to drink his waste fluid at the same time. He is ordered to kneel over an empty cube as the Primes use the catheter to make him slowly drip piss into it. It takes a full day for his bladder to be completely emptied but the relief that will come at the end of the day is absolutely worth the long wait. Sentinel is never bound when the Primes leave him alone for a full day because they know that he will not leave and miss this rare opportunity to fully empty his bladder. He obediently kneels and waits for the percentage to go down until it reaches 0%. It’s his only entertainment during the long wait.

Sentinel sometimes cannot fall asleep when he’s too full. His squirming oftentimes wakes the Prime he’s forced to sleep with in their berth. He sleeps with a different Prime each night unless he’s being punished. If the Prime gets irritated enough with Sentinel, they sit him on their face and make him pee into their mouth as little as possible to relieve the pressure in his waste tank to make it possible for him to fall asleep. The Primes always act so inconvenienced when they drink from him while they’re trying to fall asleep because they’re wasting their turn on Sentinel’s pee. After letting him pee they order him to touch their external node for being such a burden. Some of the Primes order Sentinel to stick his spike into their valve for the night. He’s not permitted to overload when a Prime is cock warming his spike.

Sentinel’s valve is too small to be penetrated by any of the Primes. Even sticking one finger (belonging to a Prime) into it is a tight fit, Sentinel can put his own two fingers into himself. The Primes still find a way to frag his little valve. They create a thin false spike that they can all connect to at the same time and feel everything done to it. The Primes force him to use it while they all watch. Sentinel tries to ignore their hungry stares as he masturbates with the small dildo on a berth. He closes his optics in order to continue fulfilling their order. The false spike feels so good in his valve because it has nice ridges and also vibrates, he can’t stop himself from moaning. He’s so preoccupied he doesn’t notice the Primes extending their spikes and lightly touching themselves. Sentinel overloads and stops moving the dildo inside his valve. The Primes reprimand him for stopping and tell him to continue spiking himself with it. Sentinel opens his optics and looks at the Primes. They tell him to go back to work because they haven’t overloaded yet and they’re so close. Sentinel is informed about how the false spike works. Knowing that all of them are currently ‘spiking’ his little valve turns him on A LOT. He doesn’t want this to turn him on so badly but it does which makes him feel embarrassed and very desired at the same time. When his second valve overload hits, he squirts valve lubricant to the joy of the watching Primes. They quickly overload from their spikes too.

The Primes sometimes take baths with Sentinel. He draws the bath and in the meantime strips the sitting Prime of their armor and then himself. Many of the Primes like to time their baths when Sentinel is especially full and is constantly squirming in desperation. They like to squeeze his armorless stomach over his bladder and feel his body tense and him moan in pain. His face scrunches up in pain so beautifully and sometimes he even starts crying a little. Sentinel always feels like he’s going to pop when they do that to him. Sometimes, he fantasizes about actually popping and no longer being forced to deal with them and their control over his waste tank. The Primes love groping his armorless protoform while he washes them because it turns them on. Sentinel touches their external nodes multiple times until they overload during these baths. After he’s done washing the Prime and himself, he dries both of them with fluffy towels. Sentinel is permitted at the end to void a little for doing such a great job and being their very obedient servant.

Starscream learns about Sentinel’s existence when he accidentally bumps into him inside the Primes’ tower. He remembers seeing Sentinel by the Primes’ sides but then he just stops showing up and no one notices. Except for Starscream, that is. The seeker tries to talk to him but Sentinel always keeps quiet or a Prime takes him away. Starscream cannot stop thinking about him. Sentinel, on the other hand doesn’t remember the last time he has used a toilet. He’s just uncomfortably full all the time and sometimes horny because of his full waste tank.

One day, all 13 of the Primes die to Quintessons during a battle and Starscream is chosen as the next Matrix bearer. He becomes taller and stronger. The liquid energon keeps on flowing while Cybertronians keep fighting Quintessons. Starscream inherits the Primes’ living quarters (their tower) and all their personal things. He later learns that it also includes their slave, Sentinel. Starscream has a hard time believing that the Primes kept a mech captive but the living proof of their depravity literally stands before him. Some of the servants and guards knew about Sentinel’s existence. Sentinel exhibits behaviors that concern the seekers. Starscream loves being called ‘master’ or ‘lord’ but hearing these words from Sentinel doesn’t fill him with joy as it normally does. Sentinel is quiet and very obedient which probably means that the Primes broke him in well. Starscream and his trinemates also suspect that he’s been sexually abused by them too.

It doesn’t take long for Sentinel to beg Starscream to let him void. Starscream doesn’t understand and Sentinel tells him about the catheter. Starscream and his trinemates are horrified but it doesn’t end here. The seekers can’t remotely control the catheter like the old Primes, so Starscream decides to remove it. They write a code to disable it and unstuck it from Sentinel’s urethra. Thundercracker is holding Sentinel up while Skywarp watches. Starscream kneels before Sentinel, grabs the catheter with forceps and lightly tugs. The catheter doesn’t want to budge so Starscream pulls it out with great force. The catheter slips out and Sentinel screams in pain. It’s quickly followed by him pissing himself while Thundercracker is gently holding him up because he has gone completely limp in his arms. They did it in a room with a floor with a drain for easier clean up. Sentinel starts crying and after he stops voiding the seekers can see blood slowly dripping out of him. Starscream looks at the catheter and sees that it’s covered in barbs. He has accidentally shred Sentinel’s urethra. Thundercracker and Skywarp take Sentinel to bathe him while Starscream is left alone in the room, looking at the torture device.

They take Sentinel to a medic and are informed that it’s going to take a VERY long time for his urethra to heal. Not only that but during this time Sentinel can’t have another catheter inserted which means that he will be continuously leaking all of his waste fluid as he’s too damaged to hold in his pee. The damage is fortunately not permanent and will heal with time. The medic puts special sponge for incontinence between his crotch armor and his opened valve panel to prevent leaks. When they carry him to their room Thundercracker gives Sentinel a towel to sit on because the sponge is not going to last very long but the towel can be washed and reused.

Starscream is very busy being the new Prime and keeps taking Skywarp who can teleport with him. Thundercracker spends the most time with Sentinel. He quickly learns that Sentinel cannot eat normal energon and needs to be breastfed. He goes to a medic to have his filtration units onlined in order to feed Sentinel and not letting him starve. He works with his trine to slowly reintroduce Sentinel to eating normal food. Thundercracker pumps his breastmilk, so Sentinel doesn’t have to go hungry when he needs to leave with his trine. The Command Trine has a hard time understanding why the Primes abused him and kept him as their slave because he’s so innocent and not evil.

Sentinel thought that being forced to have a full bladder all the time was bad but constantly dripping waste fluid is even worse. It’s disgusting and humiliating no matter how many times the seekers tell him it’s OK because his body is currently hurt and is slowly healing. Sentinel makes sure to never mention to his new Prime and his two trinemates why the old Primes put the catheter into him. He doesn’t want them to drink his apparently addictive waste fluid. He feels so ashamed because he’s unable to properly serve them without wetting himself. Sentinel feels like a failure. He keeps bleeding for a week after the catheter is removed and Thundercracker is the one who gently cleans his valve from blood and waste fluid before giving him a fresh towel to sit on. His bleeding urethra surprisingly doesn’t hurt that much, the removal of the catheter hurt like hell though. The seekers don’t give him any sponges so he can’t leave their room without leaking but Sentinel doesn’t think he would even want to leave in the first place.

When Thundercracker and Skywarp were bathing Sentinel shortly after Starscream had removed his catheter, Skywarp accidentally squeezed his armorless stomach when he tried to get him out of the bath and Sentinel nearly started crying again from pain. He was so sore after being forced to hold his pee for so long. They had taken off all his armor before bathing him and cleaned it too. After the visit with the medic, he gets to spend all his time in their room lying in their berth holding a towel to his leaking waste outlet. Starscream gives Sentinel his own heated pillow so he can hold it against his sore stomach, after he transforms his stomach armor away, to ease the pain. Sentinel spends most of his days lying curled up on his side in their berth, wallowing in self-pity.

There is one incident when Sentinel leaves the room with a sponge stuck behind his panels accompanied by Skywarp. They go to see something cool and when they go back to the room Skywarp sits on the berth while Sentinel kneels before Skywarp’s spread legs and licks his crotch armor. Sentinel wants to thank the seeker for spending time with him in a way he knows the old Primes enjoyed. Skywarp stops thinking as Sentinel manually opens his panels and licks his uncovered valve. Skywarp flinches and teleports to get away from Sentinel. Skywarp falls on the floor with a clang while Sentinel is left kneeling on the other side of the berth confused. Skywarp tells him he shouldn’t frag with people without telling them beforehand what he wants to do with them. He’s shaken and tells his trine about it, so they can talk to Sentinel about his behavior.

The other incident happens when Sentinel springs an erection while having his armor and protoform groomed by the three seekers. He’s embarrassed but the seekers tell him he can go to a bathroom, masturbate and then come back, so they can continue grooming him. All of them wordlessly decide to never talk about it. Sentinel sometimes fantasizes about Starscream abusing him but quickly stops this train of thought because he’s not like the old Primes. He misses the horrible treatment even though he knows what the old Primes did to him was wrong.

Sentinel keeps having accidents even after his urethra has completely healed. He spent so much time with a catheter and then after it was removed he has been constantly leaking waste fluid, he forgot how to hold in his pee. The Command Trines teaches Sentinel how to relearn control over his waste outlet. He pees himself whenever he laughs or sneezes and sometimes even when he moves in the wrong way. He keeps using sponges to prevent leaks and cannot stop thinking about how grateful he is to have a working waste outlet and control over his own waste tank.

aw lord..... ough

PISS BLOG IS ALIVE!I'm sorry minimus knotting roddys pee hole is so hot but.

I need rarchet to get so mad at both of them because roddy just got the worlds worst uti, and now he has to deal with the complaining because apparently rodimus can't just suckt it up like a big bot

Roddy’s pee hole would absolutely get infected after that. he’s a whiny little bastard about it, too. his pee hole is leaking and aching constantly. Minimus hates that he’s getting scolded by Ratchet as well.

[unsanitarystation]

Begging jro to see this please please please please please please please please please please please please please please please please please please

Good evening my liege I have just discovered the worst things I can use big magnus for and I can't even send these on anon dhjsgsjdh have to own up to da shame

[unsanitarystation]

Another ageswap prowl idea (based very loosly off an ask from the main blog i remeber):

The twins are out on a mission, but left Prowl with a sound in to think about them while they're gone. Well now it's been a few days, and he *really* nees to void, so he goes to Ratchet- cause that's where the twins told him to go if he had a problem- and just begs his little spark out.

He's so full and it hurts and Ratchet pleeeaasee-

Ratch feels his little tummy bulge, just to make sure of course, before unlocking his panel. Prowls' spike jumps right into the air and the moment Ratchet loosens the sound pee just goes gushing right out.

Prowl almost collapses, knees going weak at the pleasure and doorwings shivering. The sound left him so sensitive that the stream cuts off for a few seconds as he cums, though resumes as fast as ever. Ratchet coos over him once he's done, praising Prowl for coming to him as he works the sound back into his poor little spike.

Hgrhh Prowl cumming while pissing is always so hot... he's been so needy for some many days, his waste tank emptying makes him tremble and sob. mhmm

[unsanitarystation]

i think every character who has sat on a throne ever should get to piss on it

this ask is mainly about starscream but. i think everyone deserves a chance at piss

Thrones are literally for pissing... captain's chairs too. Any and all chairs. But all thrones for sure. Why would you get up from your throne once you've sat down, and just to piss? No, you gotta piss in the throne.

May I offer to you this post:

you've discovered the loophole, no celibacy week happens on the piss blog. god yes please we need to make the tfone bots pee, preferably for hours on end

[unsanitarystation]

Pee is stored in the balls… soundwave capturing jazz and ties him to a chair and just keep feeding him watered down energon until his sack is so big and heavy it’s pushing his legs apart… keeps his spike locked up so he can’t void until he answers his questions…mmmmmghmmm jazz sobbing after hours of ball tournament and getting fed until they’re at max capacity. When soundwave finally let him void it’s just keeps on going, by the end of it jazz is shivering and drooling while he watches his balls slowly shrink.

ough. that’s weirdly hot. can’t get the thought of Jazz with a really huge pair of balls out of my head. And they just keep swelling and swelling, his legs spread wide open to make room for them, until the dam finally bursts... hrghh. It’s probably such a relief, to finally release, his sore balls shrinking as the tension is voided out of them...

[unsanitarystation]

What if in his spiritual stuff, Drift got into piss reading. Sort of like reading tealeaves or something, you have a bot void into something and then analyse the flow and streaks and smell and so on. Ratchet obviously doesn't entertain it unless its specifically so he can also take a waste sample for medical testing cos he thinks the whole thing is nonsense. Roddy tho. Roddy is always for it. He's always asking drift to read his piss fortune. He loves it. He loves it so much he keeps trying to drag others into getting their piss fortunes read. He fuckin loves watching others piss and also watching drift work win win

This is fucking hilarious. Rodimus loves the piss fortune.

[unsanitarystation]

oh you have to go pee? are you like, self diagnosed
