Lipples are a pretty handy thing to have for someone with a detached head. Not just because of this, but also in case you've gone outside without your head, and suddenly you realize you're hungry. Sure, there are other places you could choose to put your mouth(s). Places where you wouldn't have to flash your boobs in order to eat. But if you do put them elsewhere, then how are you supposed to find an excuse for flashing your boobs?
I guess this drawing does fit this month's DetachedPeople inspiration theme, which is "exposed". Although, I did get the idea for this before the prompt was given, so I can't exactly say I was inspired by it, so I'm not sure if it really counts. ¯\_(ツ)_/¯
