Most of the stories I’ve seen so far on GSS are about control men and fuck them. Are there any stories about a hungry bottom hypnotized other men to fuck him?
My/ChaoticDjinn’s story on Amazon has a bunch of that. It’s reality shifting / wish granting, so might not be exactly what you’re looking for.
Try Webb025’s How to train your slave series. Parts of it includes bottoms training their tops.
You might enjoy “Mister Mister”, which is a comedy about a straight guys dick that tops him.
That’s pretty much my genre.
