I'm sure you can find that scenario thru social media. But just so you know it won't be like porn.
There'll need to be rules, boundaries & several discussions. Plus to cover yourself, paperwork on STD's etc.
If these other people are a couple then they have their own dynamic. You might be termed "disposable" if things don't work out.
There's always the unspoken issue of "competition" in size areas, etiquette & what to do with...down time...when you might be side lined.

Many things to consider that r behind the scenes.
I do hope you find what you're looking for & it goes well for you
