Amazing work i really enjoy how well made if the writing and character desing, most of all the protagonist with the developing mech, Dick size and bodybuild are wonderful, the only part i think is not enjoyble because require too much points is the training of the Protagonist Sister Mia and become too grindy, most of people want to skyp that in this kind of games. Will be really good if you can give the protagonist the possibility to finish the history without being rape or sell herself by futas and make it opcional that way you can achieve much more immersion in the run. You have a Trascendental project, if you keep developing every character sex scene add cumshoots, anal sex, Armpits sex footjobs etc... with variabilities depending of the size of the dick will be AMAZING because open the door for more runs and is give a bad taste when scenes are the same independent of the dick size,i think scene variability for dick size is key in your project. Content like this can skyrocket in popularity and be more know by people if you making available in fapping videos (ppl fapp first and if the content is awesome like yours they will seek for you and try to support for more content) with watermarks of your artist name in popular porn pages like rule34video, Eporner, PornHub, etc... Like for example Derpixon or Deepstroke with his gangbang animations (gangbang scenes here will be godlike haha)...I wish you the best.
