if wishes were horses

I kind of want a BDSM AU fic where like, a dom and sub sit in on these dominance and submission classes in school, and then they end up having all this awful sex afterwards, because their kinks don't line up with the kinks they learn in class, like maybe spanking is just uncomfortable and awkward for them or one of them finds kneeling bad on his or her knees.

And then they eventually figure this out and have lots of hot sex trying to figuring out that they're really really into humiliation and like, gangbangs or something. The end.

While I am dreaming, I would also like someone to write me Spiderman threesome MJ/Peter/Gwen fic, where MJ is played by Michael B. Jordan. Please and thank you.
