Yep on Android a lot of scenes are buggy. Chapter 1 has very few, chapter 2 some and chapter 3 is loaded with them. If you're interested I can tell you which are buggy and how. I will use joy play now as I very much want to see all the scenes. And I have FUTA on male enabled so I'm unsure as to why I can't find or get that scene, maybe a bug if it's the ass sharing with Brendan, cuz I've seen that one.
I am amazed that you're doing this alone. Thank you for your hard work.
