Erwin has a mouthful of toothpaste bubbles--which is one of the early things they discovered here, and immediately adopted, toothpaste and mouthwash--when he hears Levi pad to the bathroom door. He glances over at him and nods, but doesn't try speaking, lest he sprays toothpaste globs everywhere. They've just shared a very pleasant experience, and he doesn't want to ruin it by making a mess in the bathroom.

Erwin turns towards Levi when he comes in, expecting a hug or cuddle, and then they can go back to the bed and spoon for awhile, until Erwin calms down. Levi, it appears, has other plans, and Erwin is both surprised and delighted when Levi starts stroking him through his pants.

"What, brushing my teeth?" If that's what got Levi going again, okay! Erwin doesn't really get it, but he's happy to comply. He lets Levi drag him down for a kiss, which will be minty-fresh and clean, and Erwin wraps his arms around him, trailing his fingers up and down Levi's spine. He moans softly against Levi's lips as he's stroked, canting his hips forward and pressing himself into Levi's hand.

If Levi keeps that up, Erwin won't last long at all.
