48/52 [MF4MF] Looking for Hot couple for my Wife

We're a Married a Couple in our early 50s. Although most people think we're in our mid 40s She's 5,1 103 lbs very fit, very attractive. Brunette, olive skin, medium/ large breasts. Very feminine. Myself I'm fit muscular 5,9 192 lbs brown full head of hair. No body hair.

Looking for Couple mid 30s to mid 50s, that are definitely fit, adventurous and polite. I'm secretly looking for her to eventually play with a couple. I'm not interested in actual play just watching. My fun starts after. We can host, beautiful house and new hot tub. Perfect ice breaker for that moment. We want to be friends first. Work our way into this. She's unaware of the goal. We're NOT new to this we've had multiple 3somes with other males. This will be the 1st couple experience. I'd like it to start off as we're work related friends over for dinner. If my wife is attracted to the woman, she's be into allowing her partner to join in.

Thanks
