Thanks for the save file.
The latest update added Elena scenes at night, talk with Vi. After you progress those for a bit you'll be able to continue with Erin femdom events.
And yeah, no Elena breakfast events are in the game yet.
I see your point.
The way this story arc is structured is that you get to pick only one end scene to finish it on, so you have 4 different options.
A conscious decision I made is to have Sera's be more universally liked, and have the other endings be weirder.
If Elena's end scene was a requirement I wouldn't have made it that weird, but I think it's appropriate.
Mars was raised by a step-mother that hated him, she abused him (both physically and sexually) and tortured him for years but he still loved her and wanted her validation. His biological mother isn't as important to him. When he's talking about his mother, his almost always referring to his step-mom, not his biological mom.
So it's less to do with incest and more to do with Mars' confused upbringing.
Post timeskip, the tone will be more lighthearted and hopefully I'll get to implement the beach episode I wanted to do for ages now.
