Your Loyal Knight

but then the protagonist/character I was following in this dream found an ancient dragon and asked them about it and that dragon just did the equivalent of the Ben Affleck smoking meme then (psychically, including images) explained that no, there was never any widespread practice of humans riding around on the backs of dragons, those humans/dragons were just perverts

and the 'ancient guildhalls of the dragon riders' were the equivalent of kink clubs where certain dragons and humans went to practice BDSM and there was an entirely different kind of 'riding' being practiced, hence the shackles and muzzles, etc

the protagonist started getting squirmy looking at the dragon and listening to it talk about things they'd never even dreamed of, and the dragon noticed and kind of rolled its eyes, though was amused since it could smell how wet they were

It made a comment about how whenever they did allow themselves to stay around humans, there were always quite a few who reacted the same way, and reached out to pin the protagonist down with one of its big clawed forelegs and used the other to delicately rip the inner seam of their leather breeches and smallclothes open, exposing their puffy, wet cunt

It wasted no time in delving its massive tongue inside, rumbling about how good humans taste and how cute they are when they squirm. It was fairly large and the way it was lying, you could see where its cock started to emerge from its slit, long and pointed and ridged along the length of it, dripping wet

The dragon also explained that, obviously with the size difference between humans and dragons, the human either needed to really do a lot of prep work, or the dragon would have to use some of their magic to ensure they'd be able to fit without just wrecking the human entirely, and there was a tense moment where the dragon shifted around to rub its cock over the human's clit and folds and it made some comments about how humans wandering into its lair uninvited, asking about lewd things needed to be taught a lesson...

But it did do the magic that would stretch the human's pussy and cervix/womb enough to accommodate the dragon, though it warned that since it hadn't had to do that kind of magic in a long, long time, it didn't know how long it would last, or if it might even be permanent, but oh well, it's done now, and as it recalled, that was part of the fun some dragons had back in the day, getting humans addicted to the size of dragon cock and making it so a human lover just wouldn't be able to pleasure them again

It pressed in, and the protagonist couldn't help but sob from the stretch and how good it felt once the dragon finally bottomed out inside them, feeling just how wide they were split open before the dragon started fucking them properly. It lifted the human's hips up, fucking down into them greedily, drooling and enjoying the hot, slick hole it had found for itself, how long it had been since it had last fucked anything

Once it finally started to cum, the dragon's cock stretched even wider, the sheer size of the load bloating it out, filling the human to the point they were shaking and begging for relief because it was just so much

After a few more moments, the dragon did pull out, still showering the protagonist in thick gushes of dragon cum, and then walked up over their body to stick its cock in their face, saying it was only polite to clean it up, meanwhile the human was like delirious but licking and swallowing the cum as best they could, feeling their hole stretched and gaping open but too weak to do anything about it

pro-er tip! after they say yes, ask them if they like it, and watch them get all embarrassed and squirm their way through that second "yes".

feel the way they grind into me, stuffing me full with their hands bruising in my hips, feeling them pressed against my back, pinned down completely.
