First Time Threesome!

So... my long term boyfriend and I have always been very sexual. We love to play, using toys, lives, devices, etc...

Recently we were having sex and he started to talk dirty about having a threesome and I surprisingly went along with it for the first time ever and discovered that it kinda made me even hot over than before... like ever!!

To the point!!! We are planning to meet up with a guy for our first threesome after we had come to a full agreement from all parties and set boundaries! We are wanting to try this first with another man then... maybe another woman (based on me). Is there anything I should be prepared for? I am looking for advice from real people with real experience!!! Tips and tricks!!

Thanks in advanced 😘
