This lady definitely knows what she wants and likes.So sounds like your play is her with co workers not truly swinging lifestyle which can be good and bad. I rarely played with anyone I worked with only a very few. But that is just me. I’ve been with multipule men in many different combinations but I think the big numbers are usually at a swing club or party where I may be the center of attention so the numbers can be high some of them more than once but like you wife I prefer one or maybe two at a time not 3-5 guys all over me. May look hot but hard to concentrate and enjoy the sex.
Anyone lucky enough to be with her is blessed.
