Two watersports scenes are in the extra scenes edition. the others are available in the free build.
I have a bit of a silly questoin, if you do not mind... What software did you use to create this?
As I understand you used Renpy for the engine itself, and then used DAZ3D assets for the characters... Are there any more, or are those two sufficient to create something similar?
You can say you've inspired me a bit <3 Not sure how much will come out of it, but it would be fun to give it a try!
