Hey there, it is my first post so i hope that it was never posted before x)
The inflation moment is around 4:15 and it's the best inflation process i saw in a video
here is the link (sorry for the spanish subtitles xD)
By the way i have a request : I'm looking for an expansion comic I saw in Deviantart in which 2 girls doing advertise for a gym club were fattened up by a mad scientist.
The first process only have belly inflation but the second one includes breast and butt expansion.
So if you could help me on this point... I would be thankful ^^
(PS : I'm sorry for my english level)
