Yesssssss, more porn! And porn with so much awesome stuff going on! Love this line here: his throat tightens with something raw, momentarily overwhelmed by how attuned Clark is to him. Bruce being scared of intimacy and closeness is always great (and of course he can't stop thinking and wondering and worrying, which is why he clearly needs to get fucked into oblivion).

I love your cheeky, but still sweet Clark. Bruce riding him and being all determined and trying to wear himself out (and almost enjoying it more while he's still soft) is so fucking hot. And then all of this:

Bruce’s stubbled cheek rasps against Clark’s collarbone and his breath is humid in the crook of his shoulder. He gets a little lost in it and doesn’t remember when Clark got his hands free, but his palm is cupped at the nape of Bruce’s neck, the other in the small of his back, holding Bruce steady as he grinds down on his cock.

All he can hear is the rattle of the bedframe, his own panting and Clark murmuring, “Good, you’re so good, Bruce.” He wants to tell him how much that isn’t true, but he can feel himself starting to come, still only half-hard and trapped between them, a shuddering orgasm that runs deeper and longer than his earlier release.
IDFGJODHGDGFKJDBJD I HAVE NO WORDS FOR HOW MUCH I LOVE THIS. And determined Bruce demanding more, fuck yeah. This fill is awesome, anon author. :D
