Game stream from one computer to another?

[BradIJM]

Hey guys, 

I feel like I'm going crazy over here. Long story short, my sister was using my computer for gaming whilst I was gone travelling. I'm now home, but she still wants to use it (note: she lives at a different house) . I currently have the computer back, and have been trying to figure out a way she can remote into the computer and still play the games she wants to. 

In my head, I thought you could do this with Geforce Now, but upon more research, that would not appear to be the case (unless I'm missing something)

So, I'm looking for suggestions for a way of her being able to play the games on my computer. Looking for the easiest solution to this, as I would just go around and do it for here, but i'm currently in quarantine after returning home, and the country is on lockdown anyways. 

If anyone can help with this, that would be super helpful. 

Thanks in advance.
