This isn't exactly what you're looking for, but an idea that comes to mind is something like
$1 It's an extension that let's you synchronize what you're watching on Netflix with other people so that everyone can watch it together.
It's purpose is for people who aren't in the same place, but maybe it could be utilized in this situation. You may be able to use the description track while the other people use the normal one.
I have no idea if this would work, but I thought I'd mention it in case it's something that you'd want to try out. I've never used the extension so I'm unsure if it's even accessible.
