Having Visions About Optimus’s Post-war Soft Body Weight Gain… Nothing Too Obvious When He’s Standing

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.

they make me very unwell:33
