I’ve seen the dotm optimus action figure without his platings (I.e. skeleton only) and that has been on my mind ever since…he smol

This is related to your heat/rut au (?) headcanons- Ngl I never thought I would hear/see the words Sentinel and cute in the same sentence but now that I look more at it it does seem like smth he would do. aaand if you don't mind me asking do you have any Sentinel headcanons or maybe some for 13 primes? ;>

Sentinel in heat thinks he is just the cutest, hottest, most irresistible bot on Cybertron, and he WILL get some spike!

I will make a master post of 13 Primes headcanons soon, but I’ll give you some A LOT more Sentinel~

When Sentinel goes into heat around the Primes, his whorishness increases tenfold. His most desired mates are Megatronus, Prima, and Alpha Trion. His frame views Megatronus as the strongest candidate, most capable of producing strong offspring and defending them and Sentinel. It sees Prima as the most desirable for genetic purity, since he’s the first Prime. He’s also big like Megatronus, which he likes. Alpha Trion catches his frame’s attention because of his cat-like beast mode and behavior, which makes him desirable for his agility and unique caretaking instincts. When Sentinel is around any of these three while in heat, he will be found rubbing up on them, touching them anywhere he can, whining and purring at them, and taking every opportunity that presents itself to bare his valve at them. Upon the slightest indication of interest in mating with him, he will immediately bend himself over the nearest surface or get on his servos and knees and spread his legs.

If his three favorites deny him for whatever reason (perhaps they are too busy doing important Prime things) Sentinel will go to the other Primes and loudly complain about it with whines, whimpers, and pitiful cries of despair that might have made them think he was dying if he wasn’t venting out his heat pheromones all over the place. As soon as he knows he has the attention of one of them, he zeroes in on them, flirting via touches and more of his begging whining. If he gets the attention of multiple, his slutty aft will bare his valve to them all and watch any who are interested fight each other for first dibs. Seeing any of the Primes fight over him for mating rights makes him obscenely wet.

And when one of them finally frags him? He’s so fucking loud about it that spit roasting him is common practice, just to make him a little quieter. Except when it’s Prima. Prima, the pinnacle of divinity, adores Sentinel, and the sounds he makes when he’s taking massive Prime spike in that plush, deliciously sensitive valve of his. Especially when he’s in heat. Sentinel is so loud, in fact, that during his first few heat cycles, some of the Primes would - aggravatingly - stop mid-round because they’d think Sentinel had overloaded and was getting overstimulated, when he very much had not. It took a while, but they did figure out the signs of Sentinel’s overloads: his legs squeezing their waist so tight they can’t move, his digits digging into their plating so hard it sometimes actually hurt, his wings arching up and out and shaking with the strain of release, and his cries becoming much longer and cutting off with sobs of pleasure.

Then, when his heat is finally satiated, the Primes gently clean him up (Alpha Trion will lick him clean like a fucking cat) and tend to any minor damage to his plating, including touching up his paint and giving him a nice polish, before all the participants snuggle up around him and let him cuddle them as he recovers from the ordeal. They’ll gently pet Sentinel, kiss him, hold him, and praise him, and he will often be so relaxed by the aftercare that he will slip into recharge right then and there.

One of these days I’ll get around to finishing that dancing comic, until then heres some goofy stuff.

Huh okay

I just realised, bay op and megs (movie 1-3) doing the dirty would be so rough.

Like megs is almost twice op's size and they won't even be having intercourse, they would be basically fighting at this point.

And oh boy, Megatron's spike won't even fit inside his valve.

That being said I suppose they still gave it a shot

Full on twi again

just finished earthspark season 3 here are my thoughts

guhhh urghuuu oughh I think I hauve covid I need optimus to make megatron and prowl get along by locking their pussies together with magnets and ordering them to make each other feel good while he watches from nearby

I need to see megatron so into it bc he's used to optimus putting him in situations from their time together on earth but this is not a side of optimus that prowl is used to so he's so flustered whimpering and squirming away from megatron's fat node as it grinds against his own but every time he glances to optimus he just sees that piercing gaze and shivers needing to be good for him

prowl overloads first squirting on them both with a yelp and a flutter of his doorwings and he looks so ashamed immediately after but that changes quickly when megatron gets so turned on by how cute he is that he presses prowl to the ground to hump against him with all his strength until he's squirting too

at the end optimus removes the magnet and praises them both which makes prowl's spike pop out and he tries to push it back in but now he's got both of them on him ready to push him into another overload

anyway yeah the season was okay still felt drab compared to the first season but not quite as disappointing as the second was but I'm sad Grimlock still didn't talk and Tarantulas didn't come back like I'd hoped orz I really wanted him and prowl to interact it would've been so joever for me if he'd shown up again I would have gone insane and I'd be talking about prowl getting filled with eggs instead

...what could have been

Don't be weak

Damn I need Sentinel being all needy and his much bigger partner being gentle and spoiling him.

A pal of mine suggested Megatronus and my brain took that and RAN with it.

Part of me is like oooOH I bet he'd moan and sing so pretty and fake in the beginning of fooling around but as their session goes on and gets more intense he loses all care and his voice is reduced to cracks and breaks from begging and shouting. Sentinel being a total mess and not making sense anymore and slurring his speech while having Megatronus do something particularly nice to his valve and he's just muffled sobbing and whining face down into a pillow. GOD I want him spoiled so bad what if they bought him precious gifts like aphrodisiac candies , silky adornments and oh so many sex toys that he only ever uses once with them.

…

Oh my god what if the primes are all on a very important sudden voice call . Sentinel and Megatronus are in the same room together and were previously having a private moment together in berth but Megatronus now has his entire focus on the meeting. Sentinel , squirming under the larger bot, is not apart of the call and is ordered to be completely quiet…which he's finding to be more and more of a challenge as the call goes on.

Megatronus let's his attention go back to the needy little mech eventually.. the meeting HAS been going on for long while now. Teasing him he turns on the small vibrator that's been tucked in Sentinels aftport and immediately ups its speed. Sentinel almost SCREAMS . In retaliation he fumbles for Megatronus' spike and the bigger bot let's out a shaking GASP. Sentinel can hear the pin drop silence on the other end of the call and then someone's concerned "Are you alright Megatronus?"

What if Megatronus punishes him for it by putting a gag in his mouth. I'd imagine the makeshift gag of cloth wouldn't be near enough to completely silence Sentinel after that. Despite that Megatronus gets the call going back on track smoothly like nothing happened. All while flipping Sentinel on his front, aft up, and with one giant hand gripping the back of his secretary's head he shoves his face into the berths pillows and HOLDS him in place there.

…

Unfortunately.. it's considerably harder to focus like this as he now has the most perfect view of the little bots beautifully plump and dripping array on display for him. His own desire and twitching spike is getting tremendously more difficult to ignore. He could simply settle for more teasing, it's what the mech deserved after all,, edging Sentinel again after again all while discovering how many of his massive digits could fit into those warm tight ports..

Underneath him Sentinel manages to squirm and turn his face away from the suffocating pillows letting out a heaving trembling vent. The BEGGING LOOK he gives Megatronus.. glistening tears paired with the heated condensation beginning to form along his flushed faceplates.. Undeniably pleading for his boss' touch Sentinel makes a hearty attempt to push his back up closer to Megatronus.

Megatronus softens his firm grip on sentinel's helm ,,, OH but how he desired to give in to the glorious temptation to sink himself right in and give the beautiful mech displayed in front of him EVERYTHIN-

"Megatronus, if you are.. feeling a tad under the weather.. perhaps we should discuss these matters at another point of time?" Embarrassed, Megatronus clears his intake. He was so deep in thought he hadn't realized his venting was on full blast.
