Martin is. Surprisingly kinky, and pretty damn submissive at that. Jon isn't so much, due to his general sex-neutrality, but he's nothing if not supportive, and he's willing to try domming Martin a bit, as a treat.

Long story short, he sucks at it. He's so anxious about hurting Martin that he's stopping the scene every few minutes to check in, and Martin (who just wants to get absolutely wrecked) is simultaneously frustrated and completely endeared every time Jon says "are you okay with this ily so much you don't have to do anything that makes you uncomfortable you're in control here."

I'm imagining this played mostly for comedy and not so much for sexy, but I think a good balance could also be struck!

+Trans characters (I hc Jon as amab nonbinary and Martin as a trans man but hey do what you want)
+Martin, though submissive, is also a top, cause we need more submissive tops we're a dying breed
++Kink negotiation, esp with Jon, as the (prospective) dom setting boundaries in what he's comfortable doing to Martin
++++things are just awkward and maybe a bit giggly and they're both a little out of their depth cause that shit's cute as hell

DNW: dub/noncon(cnc is okay but also if it's their first time doing kink I question the wisdom of starting with a cnc scene ahsjjssjdj), either of them suddenly becoming sex gods or whatever
