As the title says, I'm looking to set up a threesome (obviously FFM) with my LTR. She's crazy attracted to me, so I'm wondering the best way to bring this up. I brought up the ideas of threesomes (and how I dont do gangbangs (MMF)) back when she was a plate and she seemed nervous, but brought the topic up on her own post sex so mostly interested.

I've given her 3 options for us finding another girl.

  1. a friend of hers (she's not interested)
  2. we go to a bar and pick up a girl together
  3. Joint Tinder account for F to F (I run the account)
  4. We talk with one of my old plates (she's definitely not interested in this)

She says a threesome sounds interesting (keeps bringing it up because I want one (or a few)) and is interested in the tinder option. The one rule apparently is that I "fuck her alone afterwards" and that I don't contact this girl again other than to set up more.

Looking for advice, potential issues I could run into creating a threesome with a LTR, or things I may have missed in terms of setting something up.
