Hrm. It's been a while, but I feel the need to weigh in.
When I had heard about this, that Jollyjack had taken a whack at a fetish of mine, my immediate reaction was one of confusion, to be honest. Assorting Jollyjack with this particular deviancy had never crossed my mind, but it was intriguing. I bought the comic, and gave it a read. Well done. Although I am an inflation fetishist, this one wasn't really my thing, but it is very well done. Excellent, over-exaggerated proportions and a participant having a good time of it. Good sense of gravity and immense size, too. If Jack takes another whack at something similar, I would most gladly welcome and pay for it.
