Our first couples dating was bad

I and my wife wanted to try a tinder threesome for a long time. And we don't want to invite our friends or people we are familiar with. This is our secret. So, we count on the tinder for threesomes dating app where we have met lots of threesome couples like us and single swingers. We invited a single girl joined us. She was hot and cute. At that day, we had a dinner together and went to a bar for some drink. I know alcohol can help us relaxed. Well, that was the girl's first time to try threesome, three of us didn't know what to do. It was bad.
