Your adventures have led you to find a cave full of treasure. A great dragon guards the hoard, and she thinks you'd make a good addition. 

Hey, remember when I did a poll? I don't. 

So before vanishing off the face of the earth, I made a scenario that was a poll for my next five scenarios. I took it down after voting, it's back up now just for reference but further votes won't count.

This was the #1 spot, with the description:
You're an adventurer, hunt down and try to slay a dragon, only for them to make you a plaything in their treasure hoard.

Next up:
You get found by a Gnoll (anthro hyena from D&D) woman who thinks you're cute, and claims you as her spouse.

Tested in Griffin, Wyvern + Hydra, and Dragon.

Worth of note that this is a DRAGON dragon, not an anime girl with horns. Huge, four legs and two wings, scales, lives in a cave. Human level sapience but full draconic size and sexiness. Passes the Harkness test, so no worries.

She has a big tongue because I gotta be self indulgent. Totally not so this can be made into vore stuff. Totally not. That'd be crazy.
