Three way relationships? ✨

So my boyfriend of two years and myself have been talking about thee way relationships as in more than just sex and I thought I'd ask the opinion of someone minded people on here.. We are really into kink and we wanted two subs for his pleasure, and mine.. And also so no one of us would have to be alone... We tried it once before and she left us, and now we met someone else.. Idk help please 🙈
