Jesus, what the fuck is going on in this thread right now?
All this moaning, venting, and bickering over something that is completely up to player choice. I've been nothing but nice to Rachel as her masked client and even gave her days off, so the sex scenes have always felt totally consensual because she likes this masked stranger who happens to have a remarkably similar hairstyle to the MC and sounds a lot like him. Therefore, if you want a romance path with Rachel, then this is the way. If you want to be a dick to her and force yourself on her, then that is another way. It's up to you, the player, to choose how you want to approach it.
And, yes, she hasn't left this place yet on the romance path, and do you know why? Well, to paraphrase Doc Brown, "her future hasn't been written yet." So why the complaints about the fact that she's still there? You're literally complaining about something that hasn't yet been included, which means you're complaining about something being a certain way when you don't even know what way it will be. It's ridiculous.
It's also pretty clear in games that have this type of thing where a LI may encounter other guys, that they will not do anything with them. So why the hysteria over something that's not going to happen? This whole thing is madness and whoever started it is just getting worked up over nothing.
P.S. If you want to talk about a character "raping" someone, Rachel fucks the MC when he's still asleep, so... ¯\_(ツ)_/¯
