My (25M) GF (24F) recently moved in together from situations where we both had roommates and the sex life has boomed since. She finally feels comfortable enough to try some of the things that I would consider a start towards a hotwife/stag/vixen situation like play with herself in front of me and teasing me in other ways and she sees how much it gets me going and she is starting to love doing it!

We've talked about threesomes and she knows I would be fine with a MFM threesome and while she's not currently super excited about it, she also knows that these next few months are going to be very eye opening for her and sexually freeing if you will since she can live in the moment more and not worry about roommates (or really neighbors where we're at now) so she's not making any decisions until she has time to figure out what she actually wants.

Here's my plan for next steps. She will be going out of town soon and so I am going to order her a dildo that is slightly bigger than I am. The goal is not to make it all about size but to give her a sense of potential with dicks other than mine that might be able to make her feel a certain way mine can't, bigger or not because that's what this is about: new experiences with new people and being able to experience something other than the same thing forever and I want that for her.

I'll introduce it likely during foreplay or something but ultimately the goal would be that she use that to play with herself while I watch, essentially a lightweight hotwife role-play!

Any suggestions from more experienced people (especially the women) are appreciated!
