“Now you get to help me stall them since you almost blew my cover.” Keith shifts in his lap and Shiro’s fingers tighten on his hips. “We gotta act like we’re into public shit. They’re gonna leave otherwise.” Shiro freezes where he’d been mouthing at Keith’s bare shoulder. “I’m serious, Shiro, don’t blow this fucking mission,” Keith hisses. “We’ll deal with this later.”
