Freaky thoughts are plaguing your mind but you can't post them on main? This blog is here for you!

⚠️ Minors DNI. You will get blocked. Please stay safe online⚠️

Submissions must be:

anonymous (no identifiable author or blog)

about fictional characters or concepts that belong to the Transformers franchise.

Confessions may get stuck in queue limbo (why : #1 #2).

⬇ Rules/FAQ ⬇

How does the tagging system work around here?

#valveplug : the term for NSFW content within the Transformers fandom. Always the first tag so it's visible for the ones browsing.

#valveplug confessions : on confession posts.

#not confessions : on posts not related to confessions.

#blog meta : on posts related to the blog itself.

Some posts have personal additions in the tags, warning for shitty puns.

If you think a post is missing a tag, don't hesitate to point it out in the comments!

Is this confession blog kink/fetish-friendly?

Yes, in principle. However, there's a real person behind this blog and no one is limitless. For that reason, I will ignore submissions involving organic gore, excessive robogore, incest, underage characters and non-con (CNC is allowed but make it clear). Everything else is on the table!

Is there going to be discourse on the blog?

No, I'd like to keep this blog as positive as possible! For the same reason, from now on I will not be posting confessions talking negatively about one thing in order to bring up another. For example :

❌ "Car Transformers are overhyped. Where are the smut fics about plane Transformers ?"

✅ "I wish there were more smut fics about plane Transformers."

Can the confession be about self-shipping?

Yes, as long as it's Reader x Canon! To maintain anonymity, I will not post OC x Canon. Reader inserts with specific features (ex: Amputee!Reader, Transfem!Reader, Autobot!Reader) are allowed.

Can the confession be about a crossover ship?

Yes, as long as one of the characters in the ship belongs to Transformers.

Can the confession involve non-Cybertronian characters?

Yes, it can be about aliens, humans, whoever tickles your pickle.

What if I need to ask a question?

Leave a comment under this post or in the confession box and I'll try my best to reply in a timely manner!

prowl is too lucky it’s unfair. FIVE big construction workers absolutely obsessed with you??? Can you like share dude you don’t need all that

and yet I too have the compulsion to rail prowl into the ground till he stops calculating and can only moan so

On the topic of voice kinks, tfa and Tfone Sentinel prime always has such a smooth voice that can be quite sexy imo. Bayverse Sentinel’s voice isn’t so bad either, though he sounds more like a cigarette smoking grandpa than a dudebro turned high ranking politician

Listen, young with and hourglass figured Ratchet who then gains a bunch of weight from carrying until he’s a fat old man? YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

I headcanon that Astrotrain really likes sucking spike, no reason why, I just think he would. I think he would enjoy teasing Blitzwing while doing oral just to hear him whine and maybe even bark umm but that a headcanon for another time. I also think he's a throat goat, like he likes it deeep in him. Because as a shuttle and a train, he's tightly compressed, with more layers of metal then usual cybertronian he would be less sensitive, so imagine he would really like to feel someone really deep inside him for a change. While for Blitzwing is unusual to find someone that can fit his whole spike like that, so his tuff warrior persona slips off, when he's getting he's spark sucked out of his spike.

Giving TFA Optimus an oral fixation so I can have Sentinel whimpering and whining sitting on his face as Optimus licks him through another orgasm and into crying overstimulation where his his thighs shake and his hips try to buck away from that probing tongue (only for him to overload again and again and again…)

I need to be bred by Optimus Prime. I wish that sentence didn't sound so funny. Im going to show that man the perks of organic interfacing and it will be STICKY

tfa constructicons bending prowl over and slamming their thick large spikes into him and cumming so much that he gains a cute little belly.

There needs to be more eggpreg fics and art in transformers. Let’s get more freaky with the Alien robots and reproduction.

So I'm gonna die when Lugnut sits on my face not only is my skull is in pieces, but his juicy valve is like a mask, fully suffocating me in its thick lips. And his valve is so divine it brought me back to life, so I eat him out like I been starved all my life and he is the most delicious buttery meal to bless this planet, wich makes him overload so hard, he is seeing the all spark, his big corpus with his faaat fucking cockpit tits shaking and his speech turning into glitching mess. But when his out of the game, Strika steps in and sits down on my tiny cock crushing me and killing me but again her valve is just too good so I'm alive again and so on and so on. Basically I'm Diavolo

[valveplugconfessions]

Lignut is so fucking thick its crazy I need him to sit on my face with all that fat fucking ass and crush my skull.

A perk of having a cybertronian partner is how easily they can hold you down and manhandle you into whatever position they want,, especially when they're full sized and their hands are the same size as their partner or larger 🤤

Being held to where they can rut their spike between their human's thighs and overload pressed against their hole just because they want to fill them even though they can't fit. Or being held down, unable to squirm as their cybertronian partner laps at their sex or maybe tries to fuck them with their node instead 🤤🤤🤤🤤🤤🤤🤤

[valveplugconfessions]

I want to push my face into the fat of Ratchet’s stomach and squish and kiss it, maybe bite it too. I want to ride that old bot until he’s shaking. His spike would be so thick. Please I really really need that old bot and especially him with some pudge. He looks so good with some gut.

.

[valveplugconfessions]

I need to see more tfp Optimus riding a dildo all day, even riding it while he is working on other stuff. Just never stopping, waiting so long for that sweet overload and edging himself before someone joins and makes him cum.

.

[valveplugconfessions]

i kind of miss when everyone was shipping d16 with bayverse optimus. please crush that fanboy with your metal boobs optimus (insert that one image of the boy crying next to nicki minaj's boobs)

I like to think that they can adjust the sensitivity of various parts of their bodies.

Partner has a wheel kink or something? Turn the sensitivity of those wheels way up and make them an erogenous zone. Same with rotors or wings or whatever.

And they should be able to connect a separate object, whether with wires or maybe a wireless connection. This could be a sex toy or something, but it could also be something like Optimus Prime's trailer. Optimus Prime's partner could be touching the temporarily erogenous parts of the trailer while he is watching from a short distance away or something.

micromacro skystar my love, how i love it so much. daydream about starscream with a tiny skyfire and toying with his panels getting and filling that shuttle up with just a finger. i even enjoy it when starscream is bite sized and skyfire can just pick him up with two finger, maybe even lick over starscreams valve and brush his digits across starscreams wings. they already have a big size difference normally but its not enough I NEED MORE
