First time posting on here, so I thought I'd bring over something from my DeviantArt account. http://carolusrises.deviantart.com/art/Angelic-Sausage-694651941?ga_submit_new=10%3A1500961256
The animation to this inflation sequence can be found in the web links section and is named "woman spy gets inflated".
While not the first blueberry inflation of Rapunzel I've done, it is however the most polished I think.
Here we have Sophia at the beach; she is in fact having a swell time, with her ability to swell up her body into the shape of a sphere. 
Sophia's a fun loving girl, who enjoys eating cake, playing video games, chatting with her friends and the color green. As you tell, her hair is dyed the color green. ^^

Here's a morph I found online it's a video. There are more like it however I can't find the site
"C-Come on, Queen Koopa! I'm sure w-we can figure this o-MPHH!!" Maria squealed in protest as Queen Koopa shoved the hose down into her esophagus. In comparison, Maria was about three times small than Queen Koopa, but all of that was about to change.
"Drink up!" Queen Koopa exclaimed as she turned the nozzle to the limit.
The rush of water hit Maria like a truck. She gulped continuously as she felt her body take in water. Her once small butt jetted out to twice its size in a matter of seconds. Her thighs followed, and soon her whole body was under the mercy of the hose.
"Had enough?" Queen Koopa asked.
Maria shook her head.
