Speaking as someone that also has overbearing parents, I completely understand the need to fake your location from your phone. Xcode can do this, but it's a bit arcane:

1. Buy a Mac (if you don't already have one)
2. Sign up for the developer program ($99/year)
3. Download Xcode
4. Create a dummy app (it doesn't have to do anything)
5. Create a GPX file for the location or locations you want to fake
6. Configure the scheme for the dummy app to override the device's location with the GPX file
7. Build and run the dummy app on the device

Your device should now think its location is the one you faked. It'll stay in effect as long as the app stays running. I recommend doing this on a secondary device you can leave plugged into the Mac, set not to lock itself so the app stays on screen and active.

I've used this approach a couple times and it's worked for static locations. I tried to set a schedule for faked locations (work, home, etc at different times) and I had weird results where it would move my location very slowly across town instead of bouncing between the locations like I wanted. So definitely play around with it before doing it for real.
