The mound (as in the stomach / vagina area) if drawn the level of detain in my opinion makes a huge difference of enjoyment of what I see (this includes the translation from the stomach into the vag and the meat hanging from the vag)
Basically the whole shoulders/neck/clavicle area. Just wanna touch every part of me to that section of the body and i really don't know why. like, i get kissing/licking/sucking/biting is nice in that area, but sometimes it's like i could just chop off everything but that part and roll around with it and be perfectly happy. sometimes i just wanna breathe on the skin around that area really heavily for a while.
