(as well as this one)
ideally for me, my favorite interaction is mouth/tongue-to-navel, but the caveat is that the character on the receiving end of such action should be receptive/reactive to it in some physiological way, whether it's a ticklish reaction or other sensitive reaction that may lead the character to do things like crunch her body or try to push offender away or other sensation minimizing tactic because it drives her nuts
this is to say, completely docile reactions are boring and only work to feed hesobutas
for this picture
>>2358842 , it was a cheap route, but pretend it was the very exact moment before lucia's body starts to react in a way like try to suck in her tummy while kanon there may try to pursue it anyway, and you can treat it almost like strategies of each character trying to resist/defend and the other trying to aggress/open up the other's defense in something like an mma match
what i'm trying to say is, unless you're just trying to aim for hesobutas who'll take just anything as long as it has a navel in it, there's a lot more science behind doing something with a navel to be really effective across the board, such as looking at
>>2359543 and knowing that lighting can play a huge role in highlighting the navel if all you wanna do is just show it off
but however you go about it, if the arrangement you have in mind is just so lifeless, it's probably at that point that you shouldn't even bother until you yourself become so artistic about the use of navels in a picture/movie
