Long distant toy

Hey there everyone! I have a GF that lives cross country. We are in a top/bottom relationship and one thing I would love to find to help with the distance is a vibrator that I can control On my phone. I see a lot out there but I need one that can be put in both holes at the same time and can also be used out in public. Meaning it will not just pop out if walking around. Now if she wears it out in public that’s up to her but if she’s home I want to make sure I can use it when she doesn’t expect it. I have not run across something like that yet so just seeing if anyone has and if so what’s the best options.
