Visible hickeys are definitely out of the question but the scrape of Akihiro's teeth has Mitsuki thinking about other places that nobody'd see. He's a little embarrassed at how quickly his mind goes there but that's what they're here for, isn't it? So he tucks it away as Akihiro sets him down, but he doesn't dismiss the thought completely.

He lets his hands slip off Akihiro slowly, not sure where he's going to go, but when he does move farther away it's for a very good reason. Now that they're going ahead with this, Mitsuki doesn't hide the way he's watching as Akihiro peels his undershirt away. He even sits up and reaches out, fingertips tracing a scar on Akihiro's upper arm as he looks over the rest that he can see.

"This is from traveling with CEOs?" He's kind of incredulous. Sure, he knew Akihiro could fight and probably had fought before, but this still isn't what he expected.
