I'm gonna be honest, I really liked this game. It was a cool game that even though it had a sandbox, it wasn't too annoying. Sure it had bugs, but it wasn't too bad. That said, adding NTR is where I draw the line. There were some sharing options where you could share MC's aunt with the cucky husband, but the fact that Mary is getting NTR is the last straw. I defended this game because it was generally pretty wholesome. There were interesting development, but yeah, there are some forced things that are just never gonna be my cup of tea, regardless of avoidable or not.
Mary was my favorite character going on because she had a "past" and it might have included sex with other guys, but you never leaned on it. It was like, she was starting over from scratch with MC, but now that you're like "but what if..." it puts a bad taste in my mouth. Instead of completing the transformation, you are instead adding a way for her to continue being that past self.
Just so you know, I'm a big hater of sharing/NTR content, but your game did a pretty good job of handling realistic situations, but adding real content and revealing some Unnecessary details about Mom, and all these characters. I'm done and it's sad.
