This is truly a masterpiece of giantess porn and probably the best the poser genre ever had. The meticulous emphasis on slow growth, reactions from all characters, and the changing power dynamic in a relationship are carried consistently throughout all 4 image sets and it creates a full experience that many other works in the media have trouble comparing with. Occasionally the literature side will will have even better growth, but never successfully juggle this many characters, instead getting sucked into just the interactions between the man and woman rather than how the entire friend group or society as a whole perceives the growth. There is an aspect to giantess fetishism that is inextricably linked to shame, partly because it is a shameful fetish, and to have the characters reckon with the outside world helps sell the feeling of planting yourself in the male lead's shoes (if that is what you desire to do).
I feel like I could talk all day about this piece. I've came buckets to it and I find myself returning time and again years later. I feel that it is tetsu's most ambitious work (that he has complete, at any rate), and hope that as he continues his life away from creating erotic content that he can feel some pride in this accomplishment. It's just so much more real than any live action porn could wish to be.
