Como logro convencer a una madura para un trio?

Hello Porn people, this is my first post, I was hoping to find help from someone who has had an experience similar to mine for this project I'll tell you the context quickly My ex told me she's bi, and that recently she wanted more women, as I've always had confidence and friendship with her, she said she was very interested in milf women, the thing is that while we were at bars I proposed to her if she wanted, she could try to hook up with ladies and try to have a trio, she thought it was a joke but eventually accepted the proposal How do you talk to a milf or how do you get into this environment? We both have the same age of 22 years, and honestly this is something new that I'm excited about, how did you manage to make something like this happen? I appreciate your help and if it goes well, bring some material as a thank you.
