The artist asked the question of “could I” instead of “should I”
at this point it is more of the uploader here who should be asking that question and start looking at the upload guidelines. It is fine to have a fetish and you can save anything of the sort to your own computer but......please do not put that here. There is a difference between gigantic breasts and "hyper" body parts.
Honestly, as someone who dislikes all the stupid gigantic breasts, this is more tolerable to me. This looks more like she's just stuffing the neck of a giant sack up her shirt to act like the giant overstuffed sacks are her breasts than anything that actually looks like a part of a human figure. (In fact, it kind of looks like she has an A-cup under her top that she's stuffing the opening of the sacks into.)
It's one of those things where it crosses so far over the line that you don't even recognize it as being in the same county as the line, so it doesn't bother you as much as something that was trying to skirt it.
