My girlfriend and I(together for 6 years) are pretty solid and we love each other a lot, and we wanted to enter this lifestyle(mostly she having sex and me watching and participating sometimes) and after a lot of discussion about hardcore stuff with hung guys, she potentially becoming Queen of spades or having trains ran on her we somehow landed on the idea of romantic threesome with my best friend, who I am very good friends with and she expressed she finds him attractive and wants us to have romantic threesome with him, what do I mean by romantic threesome( no hardcore, love stuff, kissing and hugging while he creampies her, later both of us cuddling her and ...... like that with her in the middle of us). I just want to add that my friend and me are not BI, we would be doing everything to her. So what do you guys think ?
