Tony had missed this, when Steve was small and hadn't remembered that they were a thing. Mind, it was sort of a relief that he hadn't remembered, considering it would have made it that many times harder on both of them if he had. Steve had been a cute kid, but that was as far as Tony's brain would let him go.
Still. It had been a really lonely week, and Tony'd felt like he was missing out on something huge and important even while little Steve had been right in the other room.
"Well," he said after a beat where he was just enjoying the contact, their legs tangled together and the good feeling he got from just having it again (Tony was, no doubt, going to be clingy for the next few days), "I'm glad it helped you. You're not going to go off to go steady with Natasha, then?" He knew Steve was being serious, but Tony couldn't help but poke fun at the idea of it.
