Aoba does indeed follow, without so much as thinking about it, thus basically confirming everything Noiz suggested about him. He does rush to catch up, for what it's worth, and before long they're walking together equally.

... Actually, is that even okay? Belatedly, Aoba wonders about that, considering their different statuses. But it's not like he could lead Noiz around on a leash (much as the guy deserves it sometimes!), and a furtive look around reveals no judging looks. He breathes a quiet sigh of relief. Well... it's not like those submissive tattoos are all that obvious from a distance, are they?

"A whore-...!" Aoba cuts himself off there.... in spite of having said the 'bad' part already. "That would be terrible!" Or so he assumes?? It's not like he has experience, but being used for sex that way, especially by multitudes of strangers, seems pretty terrible to him. But what are the alternatives?

"..."

Yeah, he's thinking about it. He can't not think about it, but at the same time, he feels a little bad for doing even that much. Somehow, it feels like taking advantage of his position in the system at Noiz' expense, even though he would really only be doing it for Noiz.

Unintentionally, he slows his steps, falling behind a bit. Rather than catching up again, he stops walking altogether. "Do you want -... That's not it." Of course Noiz wouldn't want it. And he shouldn't! Who would ever want to legally belong to another person, even if only on paper. Taking a breath, Aoba tries again. "If you need a contract, I can give you one."

It's a serious offer, but he's so Extremely Serious™ about it that it almost circles back into seeming silly.
