I did this in a threesome with a co-worker and her husband on 2 occasions. Met at the hotel in mid-afternoon and chatted in the lobby after they got the room key…then all three of us went to the elevator together. The front desk staff watched us the whole way with wide knowing eyes. Lol
I’ve had this exact experience as the lover…I got to the hotel room and the wife immediately dropped her robe to show me her skimpy lingerie…she then got on her knees, unzipped me and started sucking as her hubby sat at the little table in the room and watched her working me. It was incredible.
