Before they can completely separate to finish washing, Levi reaches up and holds Erwin's face in both of his hands, looking into his eyes.

"I won't."

So as Erwin finishes swishing out his mouth some minutes later, Levi trails after him, appreciating the line of his broad shoulders, the expanse of his back down to his waist and clean, fresh skin. Each of Erwin's scars are well familiar to him, the landscape of survival. It's all beautiful, to him.

He pulls on fresh sleeping clothes - which mostly amounts to underwear and a shirt filched from Erwin that hangs almost like a very short dress, stopping at the top of his thighs, and eventually clambers into the bed, tugging Erwin in close that puts him within easy reach for kissing.

And Levi does lean in for a kiss immediately, planting it right on the bridge of his perfectly chiseled nose.
