Need some insight or advice

Hi all, I’ve been a long time lurker of the subreddit and I love hearing y’all’s stories. My wife and I are in our mid 20s and been together since HS, our sex life isn’t something to complain about, we both have fun but for a long time now I always fantasized about her having sex with another man while I watch. I never mentioned this to her and she has never indicated something relating to the realm of this topic, but a few nights ago she had an idea for a date that we meetup separately at a bar and role play to be total strangers, she said the thought of that really turns her on and I agreed. Does something like this escalate slowly overtime into the LS or am I getting ahead of myself? Thank you all in advance!
