Curious about this too... it's such a hot niche but not sure how most SPs would accomodate this? Definitely met girls off fetlife that are into it though LOL
Hard to find but you might get lucky.
I had a girl in Seattle I was seeing on and off for a while who has on OF page where she performs with men. Before my first visit I asked if we could watch her videos together and she loved the idea. Afterwards she asked if I would be interested in a MFM with her sugar daddy.The first time was strictly MFM and was a little weird as expected but a lot of fun. The second meeting was more of a cuckold session with me watching then taking over when he was done. We did a few variations on it during the year.
I haven't had any luck with it since. I spend a lot of time in Van these days and am hoping to find a lady up here that is into it.
