and they won't let him out until they do the freakay ORRR [insert seeker] is completely on board and just can't wait to force this hot little bot down and shove his weird seeker spike all the way up to Sentinels womb.
Secret third option ofc being Sentinel bouncing on it crazy style

He would legit have a breakdown of epic proportion from finally being able to let down his guard, like, crashing out so hard he needed to be induce into a medical coma

Oh that just so cute

I think it would be fucking hilarious if they actually fucking like eachother, Megatron being pleasently surprise by this Autobot and Sentinel is so deep in denial he circle back from crash out to chill

You would think a creaky old mech would have trouble with two young sucubi but Sentinel and Optimus has never been more well fed, a bit too well fed actually

He decided to put them both to work as nuns as community service

Tfa Sentine, on the other hand, exude so much weanie energy that he attracts tops exclusively, hell, he turns people into tops with enough exposure

The closest TFO Sentinel can get to topping is power bottoming, he's a mean bitch, he can manage that

This make me think of some bot ugly crying as they desperately rut into that plush valve as SG Tarn gently but firmly recite tenets of the Decepticon cause

Though, now all I could think of is how all of the Primes would react if Primus where to appear and congratulate and express approval for all the things Sentinel had done made the story so much more interesting, especially if they all think Primus was "Good"

This remind me of another au of your, where Primus welcome Sentinel with joy because he play the villain so well. Prima being the first & closest to Primus being privy to the reality of the world, knowing how the "story" is suppose to go and how a "villain" is needed, so he went with the lesser evil

Sentinel face-sitting Airachnid and casually playing with her spike, chatting on about his day while fiddling her spike like it's a toy while he smother her with his pussy

Oh, this is interesting to think about, even if they are disturbed, they have no right for both have each other blood on their hand
