Threesome Advice

Ry

My boyfriend is older than me and i love him. He lets me experiment with other women since i didn’t really get to do that in college, I’m not in my final semester of college and we have had one amazing threesome. I want to have another but i don’t know how to talk to another woman. He gets turned on when i flirt with other women, he even lets me kiss other women. I want to bring home a beautiful woman for our enjoyment but I’m not sure how to go about it. Any suggestions??
