Getting too physical with Levi always carries an inherent risk; Erwin has seen him lash out at other people enough times, and been on the receiving end of it a time or two himself, to not understand the danger. As far as he's concerned, the danger is half the fun, along with the fact that he knows and trusts Levi won't harm him. Dancing on the edge of getting thrown across a room is hot, and no one will ever convince Erwin otherwise.

He lifts his head just a little, his mouth still close to Levi's skin, just above one of the pulse points in his neck. "Can you put the pillows under my right shoulder, please?"

Being on top when you only have one arm to support yourself is difficult, and the pillows will help Erwin keep his balance.

Meanwhile, he turns his attention back to Levi's throat, trailing long, soft kisses down the length of it. When he gets to the base of Levi's neck, where it joins his shoulder, the kisses get harder, more insistent. Erwin isn't biting, but odds are Levi is going to have some bruises there come tomorrow morning.
