Tony's still riding the wave of the afterglow when he suddenly feels the way that Steve scoops him up, and he huffs out a soft chuckle under his breath in surprise. It's probably a good thing is lifting him up, he thinks for a moment, because attempting to get up after that would be highly unsuccessful. His whole body feels too relaxed, and he has a feeling that he's still weak at the knees.

His thoughts derail completely, though, when Steve tells him that he loves him. This isn't the first time that Steve has uttered the word 'love' between them - after all, he has already thrown him off beyond belief after that first real conversation - but this time Tony doesn't look like a deer in the headlights. He looks surprised, yes, but it's not shock anymore. It's not panic at now knowing what to say, or how to respond.

Instead, once they cross the threshold of the door, he answers just as quietly. "I love you, too." When Steve sets him down, he immediately wraps his arms around his waist, looking up at him with a look that makes it obvious he's not saying it because he feels pressured to say it. He feels it, he knows he loves him, and he brushes his lips against the edge of Steve's jaw. "I love you, Steve."
