Well, Isla was what some people call a spaghetti lesbian (straight until wet) as evidenced by the fact that she did have orgasms and sure looked like she was enjoying it.Isla was not lesbian at all. Her mother was coercing it into it. That's why Patreon objected. Either way, it's not exactly big chunk of content, nor that exciting. Isla's model wasn't that interesting to me. Sidra looks great though.
Apart from that it doesn't really matter if you weren't that into it. There's a lot of content in this game that I'm not into but I'm not gonna dump on it because I understand that lots of people are into different things and the developer is trying to make sure there's a little something for everyone.
