okay so first of all when i was first getting into twice i wrote a mimo fic (long since vanished) where momo had a vibrator inside of herself and mina was the security guard asking her if she had any lithium batteries and momo blurts out "... do vibrators have lithium batteries, or are they just, like, double a?" and mina stares at her in complete shock and awe and lo and behold on the security scan the only thing that's been picked up is the vibe. and mina asks "i'm going to ask you one more time do you have a lithium battery" and momo says no and mina like pinches the bridge of her nose takes momo to a back room and says "ma'am, there is something inside of you right now that could possibly be a lithium battery. you cannot fly with a lithium battery." and momo says "... no, there isn't..." and it gets to the point where mina has to take it out herself (which is a form of foreplay and theyre both turned on) and it's got an alkaline battery. which is not a lithium battery. mina tries to explain that alkaline batteries are dry batteries which CAN be taken on planes, and apologizes profusely, but momo just kind of tilts her head and goes "uhh, it's not a dry battery? it's pretty wet... because of me........."
