Unfortunately, Levi is rather distracted by lips on his neck again, not quite realizing how close the other man is. It seemed as though Erwin had wanted to draw things out, since Levi had been too good earlier, he's not really sure if he should be doing anything to help him along yet. In truth, he's lost a bit of the thread of expectations here, just keeping his thigh in place for Erwin to rub against, since this seems to be what he wants. But surely Erwin will at least say something before he just creams himself in his pants...right?

Maybe they made this too complicated - maybe he should have just gone for it right there in the kitchen and shoved his hand in his pants and helped him along. But he'd been too - unsure.

Slowly, one hand leaves off to snake between them, attempts to catch Erwin as he ruts against his thigh, rubbing him with his palm for a few strokes (fuck he's thick and hard, and it's gotta be uncomfortable with something like this still trapped?) before popping the button of his pants.
