Sorry, Levi; Erwin has cottoned on to what's going on here, and it is taking all the restraint he has to keep from just pouncing on the bed. Now that he knows what to look for--those soft sounds, the way Levi's muscle moves and flexes in his hands, the way Levi watches him through half-lidded eyes--it's impossible to miss.

As he moves his hands up the length of Levi's leg, Erwin chases their movement with his lips. He doesn't spend much time on the ankle or the calf, besides stopping to kiss his way further up. No, he told Levi he would work any tension out of his thighs, and that's what Erwin intends to do. To make it work, though, he climbs up onto the bed, getting himself between Levi's legs. By the time his lips have reached Levi's knee, Erwin is sprawled on his stomach, using his elbows to prop himself up, and has one hand on the inside of each thigh. He gets his thumbs down under Levi's legs, so he can at least pretend he's still thinking about a massage, and works them into Levi's hamstrings (which are actually pretty tight, he thinks; a real, proper massage later on might be in order).

As he starts kissing up onto Levi's thigh, Erwin glances up, trying to make eye contact. If Levi doesn't want this, now is the chance to say so, and Erwin will retreat immediately. If he's still game, though, Erwin has quite a few ideas about where to go next.
