"Someone gave her a chocolate, and when she arrived home, she decided to eat it, moments later the chocolate began to grow uncontrollably in her womb-"
Hold on, description, I'm gonna have to stop you right there.
If she ate it, what the hell is it doing in her womb? That is absolutely *not* part of the human digestive system. I mean, I'm letting the magical growing chocolate slide since this is inflation fetish work, but that's only an excuse to ignore the limits of human elasticity, not the placement of organs.
It's kind of like when people make muscle fetish stuff and go "fuck it, just give her like 17 abs".
...I got way more worked up over that than I thought I would. Probably not a good idea to be doing this while hungry.
