It's not hard to decipher those physical cues, tangling their legs and bringing his knee up to fit between Erwin's, pressing firmly against the bulge between his legs that must surely still be there. He shifts experimentally, seeing if it's possible to give him a little bit of friction by rubbing there, and shudders when those insistent lips find another sensitive bit of skin. Every so often he noses Erwin back, seeking lips for lips and a brief reprieve from the attack on his clavicles. The hand at the back of his neck stays there, thumb stroking idly along the line of skin just under his ear, while the other slides over that broad, beautiful back, feeling old scars and the length of his spine and the movement of muscles under skin. He can't quite reach his ass - damn his long, gorgeous upper body - but he can scrape nails against ribs or over vertebrae.

Levi exhales, gray eyes slipping closed just to concentrate on the sensations, of the feel of the man beneath his fingertips that alights little fires on his skin.
