i'm naturally polyamorous. i have long term male partner and very recently we've been lucky enough to add a third for occasional play. she is already interested in becoming part of a poly relationship with us. this would be great news to us, but she's vanilla. we havent disclosed our bdsm lifestyle with her. she is very young and i'm not sure if she even has an inkling about bdsm. she is very kinky for a nilla, and willing to do anything! we'd love to try poly with her. but bdsm is important to us and cant be left out of the equation. my question is, how do i broach the subject with her? is it responsible of me to encourage her in this direction since she's very impressionable? i'm afraid she'd go along with it just to please us. any thoughts?
