When you find out, let me know lol have you checked out camming sites? I know its not games, but still... 

I don't think there are many ways to interact via games,  however in the past myself and a partner either just gave each other open control or set a pattern via the app while we played various games together, sometimes just one playing the other. Generally seeing if we can break the others concentration and what not.

What kind of games are you trying to play?

Video games - haven’t done these!

Connect with creative user - they could send patterns if you guess the right number, guess something about them, etc.

Chaturbate - connect your toy and see who will send you vibes

mirror life but its not very good. There's also 3Dx chat which requires a sub and then the only other one thats worth considering imo is viro playspace on steam. Though you do have to buy all the dlc for extra content and they're mostly geared towards men anyway but would still work with womens toys, The situations and positions obv wouldnt matter though. The best solution is to find someone to play games with and try and break their concentrating while gaming together or comtrolling each other etc.
