Erika's just sitting there relaxing, looking hot without even trying of course. I felt like doing this animation because it's literally what my minds eye sees whenever I look at that first pic of them 'girls on a wall' and see her giant German tits spilling out of that bikini top. Her giant jugs swelling with every breath squeezing them.
Lore: Anthro-cars obviously don't have to breath like traditional humans in this fashion. But AniMECH did many test screenings with people in the early prototype days, a big hurtle was overcoming the uncanny valley type issues. Even though unnessessary, the found that programming in an involuntary movement to simulate breaths and incorporate into other reactions ie: exasperated breaths, panting when tired ect.. made people much more easily accept them as living things and feel more comfortable around them
