That would be gross, and Erwin will be thankful for Levi's diligence later on. Right now, he's too floppy and warm and delightfully empty-headed to really care.

Erwin makes a soft, happy purring sound when Levi joins him, and he wraps his arm tight around Levi's shoulders. He's well aware that Levi will probably get up and do other things for awhile, but Erwin appreciates him sticking around as he drifts off. This time, Levi shouldn't be too inconvenienced; Erwin can already feel sleep tugging him down.

"Should do that again sometime." He plants a kiss on the top of Levi's head.
